Customer Reviews

We had great service from start to finish. The salesman visited our home for the initial quote. He was very informative and we understood the quality of the products and the process to install, but none of the hard sell, which I really liked. We accepted the quote. The guys who installed did a professional job, worked cleanly and took all their mess away. They even did the hoovering when they were finished! The products speak for themselves, they are such good quality. We feel like we have got much more for our money by choosing 5 Star. All staff who we have dealt with have been professional and super friendly. We have no complaints. 100% recommend to anyone. Good job 5 Star, thank you.

From start to finish the service has been amazing. We used the website to organise a meeting for a quote. Luke came out to us he was very knowledgeable and helpful! The installation team were great too, very professional and quick. Would definitely use 5 star again and recommend to anyone interested. 

We recently (April 2025) had a new front door and four windows installed in our house in Fortrose, Highland Region and are delighted with the high quality of the products and the skilled workmanship of the installers. The composite door is of the high quality we were looking for since our house faces the sea (about 150 metres away) and the prevailing wind. Despite several days of severe gales and driving rain, it has already proved its worth - an enormous improvement on our previous door which although double glazed allowed the wind to penetrate round its edges. The four PVC windows we had fitted on the north facing side of the house are also impressive. As well as having a high standard of insulation, they are also very attractive to look at, as has been commented on by several visitors. The whole process from the first survey through to final installation was first class, especially the efficiency and friendliness of the staff from salesman, surveyor, receptionist and installers. We should add, that we had a conservatory and garage conversion carried out by ERG Scotland about five years ago and were also very impressed by them.

This is the second time we have used 5 star windows. First time we had all our windows changed which have exceeded expectations and they look fantastic. Most recently we have had a set of bi-folds doors to replace a window. I am absolutely over the moon with them, they look amazing, the quality is second to none and the service has been outstanding. They have given our living room a new modern looking twist whilst creating a great connection with the outside. I would highly recommend this company. I cannot thank them enough!

As above. Stronly recommend.

Installation crew (3 guys) were punctual, polite, very hard working, very helpful & nothing was too much trouble. Each evening they left our house very clean & tidy. We are very impressed with the products, which replaced 23 year old Trademark doors & windows. The latest products are a great improvement. Thank you very much to everyone involved. Best wishes, Angela & Colin.

Recently had a new back door installed by 5 Star. Great job. Totally satisfied.

We've had Premier Windows and Conservatories previously to fit new windows, doors and conservatory roof to our house at different times over the last 25 years, always with brilliant service. We now needed 2 new windows in the garage to replace old rotten wooden ones and to replace an old sash window which hadn't been done previously as it is internal to the house due to the conservatory. We didn't even look elsewhere as we have had such good service in the past. The quoting process was excellent with really good advice about the best way to replace the sash window. The wait time for fitting was not too long (and was even sooner than quoted). On the day of fitting, the guys arrived on the dot and got cracking straight away. Dust sheets were put down to protect carpets (and even a dust sheet at the back of the garage). The job was completed to a very high standard and everything cleaned up and all rubbish taken away. The result was better than expected - especially the sash window replacement which we weren't even sure about having done. Cannot recommend this company enough.

We had a traditionally built garden room attached to the back of our bungalow. The workmanship of all the tradesmen was exceptional and of a high standard. Everyone, including suppliers of equipment and materials, were extremely considerate and polite. We cannot praise this company enough as they had very limited access in which to achieve such a lovely spacious room. From initial enquiry to end of contract, administration was of a high standard. We can't thank them enough for our beautiful room.

New windows in cloakroom and attic fitted in an old farmhouse.. Very pleased with result. 5 Star were a pleasure to deal with in all aspects from start to finish. Very polite and professional staff. Prompt and clear communication at all times. Would definitely recommend and use again.

We approached 5 Star Windows to get some ideas for replacing an existing,slightly leaking, twenty five year old roof.We were very impressed with the choice offered and,although not the cheapest quote, we decided to proceed as we had heard some good reports about the company. We were very impressed with the service, the staff and most importantly the finished product. All completed within the given timeframe and to a high standard. We will certainly use the company again when their services are required.

Had my conservatory roof changed from all glass to tiled roof .The workmen turned up on time, produced a high standard of workmanship and left clean and tidy each day It has made a difference in the hot weather and is far more bearable with the heat

Very pleased with the way the whole process from planning to installation went. No pressure to purchase from the showroom staff just helping us to find suitable products to suit our needs. The work was carried out over two days and work areas were were left clean and tidy at the end of each day. The fitters arrived at the planned times and discussed what they were doing as the work progressed. Very pleased with finished product and would certainly recommend Premier to others.

The men from ERG windows Invergordon were very nice. They got on with the work and the job looks great ...I'm very pleased with the results 😊

Easy, no stress and good communication, all round great company.

Really human interaction with the firm. First the salesman was polite and considerate, second the office were really good to deal with and lastly the fitter worked hard, was professional and good humoured. The door is great and looks just how we wanted.

We engaged ERG to replace our old windows and install new patio sliding doors onto a new decking area. The ERG team were responsive to our requirements, completed the installation quickly and efficiently and left the site perfectly tidy. The work was completed in 2022, and I have delayed this review for 2.5 years in case there were any subsequent problems - there have not been, and we are delighted with the work. We have no hesitation in recommending ERG.

Ordered 2 composite doors front & back of home address. Impressed by ERG price and payment options initially so ordered products through them. Very professional fitting of doors and delighted with communication and after sales service. Excellent guarantee so peace of mind for the future. Would certainly recommend them for this type of work.

Excellent work from staff today. Arrived on time , gave me good detail of how the day would proceed. Carried out the work with minimal impact or myself. Following the work everywhere was left clean and tidy. I will certainly use them for future work.

3 x Windows and a door installed . Installed with no problems by Dan & Honda pleasant lads many thanks

Kieran was brilliant, polite friendly and efficient, he did a great job we are very pleased with his work. Happily use ERG again and would recommend them. Thanks ian

Easy,fast installation, no mess, lovely door,istaller good with my dog! Would recommend company

From first meeting with the sales team and subsequently to installation, the whole process was very good. Meeting the installation team was first class and they did an excellent job. Interaction with the showroom was also excellent. Would have no hesitation in recommending TradeMark to others.

We live on Skye and had our conservatory rebuilt by ERG Scotland last August (2024) as our old one was leaking and was too hot in summer and too cold in winter. ERG replaced all the windows and doors and put on a fantastic new "Ultraroof". I decided to delay writing a review until after it had endured its first Skye winter and everything the elements could throw at it over the recent months including some severe hurricane force storms. I am thrilled to say the new conservatory has passed its initial test with flying colours. We now have a wonderful room which we can get much more use from throughout the year. Add to that the friendliness and helpfulness of the team that installed it with minimum fuss and exactly when they said they would and I really can't praise and recommend ERG Scotland enough.

We heard great things about ERG, their service, quality and customer care - so having checked around with other companies ERG came out tops! We had a tremendous service from Colin in Sales, David the surveyor and finally the most important part the installation by James, who did an outstanding job in fitting our new windows - absolutely faultless! We highly recommend ERG for their quality and customer service which was outstanding and WOW a 20 year guarantee! Hunters, Wick

Brilliant service

We went with Eden windows as recommended by the company installing a new kitchen for us and are so glad we did. The whole team were great start to finish from Graham in sales who made sure we understood our choices and the safety implications, the surveyor (I think called Steve) who had a look and measured up etc, Dan at the Gillingham site who quickly dealt with some paperwork issues and Ryan and Lee who installed both sets of doors. They worked efficiently together and were very clear about what to expect and great at cleaning up after, they also ensured we knew about door/ lock care for our new doors. When we get to the point of needing to replace windows we will not hesitate to contact Eden.

I recently had 7 windows and a patio door fitted by 5 star. The whole experience from quotes to fitting was excellent. No pushy sales, people always available to talk to on the telephone, fitters were very thorough, helpful and tidy, would definitely recommend this service to anyone looking for new doors and windows.

We had a great experience with 5 star windows. Right from the initial consultation, the gentleman called Patrick who came to give us some quotes and show us some ideas was friendly, professional and informative. The instillation day of our new door went smoothly and the installer came on time, worked efficiently and we were so pleased the the results. We have even noticed our home is so much warmer now with our new door. Thank you so much to the team at 5 star windows. ⭐️⭐️⭐️⭐️⭐️

I recently had a new front door. Apart from a few small blips along the way I am pleased with the final outcome and service I received from 5 star. The office staff were readily available on the phone and the fitters were all very professional and friendly during their time here.They left everything clean and tidy after they finished their work.

Excellent service from start to finish, no hard sell, wonderful advice, no pressure, fixed price given no haggling or offering to drop price pressure. Fitters were really good no mess (10 windows) & done in under 2days. Would recommend.

I have nothing but praise for this company. Friendly and efficient service throughout with no pushy sales speak. The showroom is great to look around, and get ideas about what you want or don’t want. The price was fantastic for the quality products provided. The survey at our property was thorough with great communication, pointing out every last detail that we needed to be aware of. The fitters were friendly and efficient and tidied up extremely well as they went along, both indoors and out. From walking into the showroom in about mid Jan to have the windows and door fitted this week (end Feb), everything was just spot on, I cannot find fault with anything. Highly recommended.

This is the third time we have used Premier windows and we always find them to be excellent. They discuss thoroughly the type of window you want before placing the order; give you an agreed approximate date of fitting well in advance and then when they start the job they arrive on time, explain what they are going to do and get on with it in a tidy way with minimal disruption.  The quality of the windows is excellent and we no longer have draughts around the frames. The price always seems to be good for the quality you get. We would thoroughly recommend them. They also sorted out our front and back doors which haven’t fitted properly since before we moved into the house. They now shut easily and open smoothly.

From discussing what we needed to measuring and to hardworking fitting staff, the whole thing was excellent. We were very well satisfied with the result.

Great service from start to finish, Valuable advice from sales team on deciding requirements & brilliant fitters who worked tirelessly & left no mess. All at a reasonable price ( no dropping price when talking to manager back at showroom, reasonable price From beginning which was fixed). Have already recommended to rest of family.

Excellent service and a quality job. Competitively priced and didn't have to wait too long to be fitted

Chose 5 Star windows for our conservatory as there was no pressure selling or any annoying sales patter. Ben the salesman changed our design a few times until we were happy with the final design. The fitting crew and other trades were great. Really happy with the finished conservatory.

My experience with 5 Star Windows has been all positive. Communication has been excellent and the fitting of my bathroom window was done efficiently by a pleasant fitter named Tim. I have already recommended friends and family to 5 Star and I personally won't hesitate to use them again.

Thoroughly professional company providing a quality product at reasonable prices. A glazing company I can heartily recommend. I will use them again. From deciding on product to installation I can't fault any of the team. Every one who I had dealings with was polite and efficient

There are many glazing companies out there so it is often difficult to find one which actually lives up to its advertising blurb. ERG were recommended to us by friends and local tradesmen who had used them in the past. I have to say, we weren't disappointed. From start to finish the people we dealt with were thoroughly professional, courteous and efficient. The products are of an excellent quality at competitive prices and were installed with care and respect for our property by a team of two who completed the work in a morning. I wouldn't hesitate to recommend ERG to friends and neighbours and look forward to having further work done by them in the future.

I have recently had 2 external doors, patio doors and 12 windows installed.  I found all staff throughout the process professional and efficient and the process of ordering the windows and doors worked incredibly smoothly. The engineers performing the installation were considerate,  efficient and very helpful.  The new windows and doors were well installed with minimal disruption and inconvenience 

I don't normally do reviews but I felt I had to this time, What a Great Company to deal with from start to finish all of the tradesman were excellence in their work and we are so pleased . The pricing was great compared to some quotes we had . If you are thinking of having work done please use Amber Home improvements , you will not be disappointed. Thank you Amber

An excellent service provided by Premier Windows, right through from viewing options in the show room, to survey staff to the super fitters. A professional job carried out and we are delighted with the finished article. Would definitely recommend.

What pleasure to find a company where great customer service values still exist. We have been given wonderful service from the start of our interactions with 5 Star and the fitting was fast, efficient and very tidy and clean. The fitter explained everything and ensured that we were happy prior to leaving. The office staff are also a pleasure to deal with and I have no hesitation in recommending 5 Star for door installation. Our next projects will see them first in line for our business. 

Really pleased with our replacement doors and windows, staff were polite & really good workers. tidied up all the mess.

The actual windows installed were of a higher quality than I expected. The fitting team did an exceptional quality installation and left the rooms immaculate. I was so happy with the work to replace my front windows that I have requested a quote for the back windows to be replaced. The quote was acceptable and I have ordered this extra work. Kevin Carroll

This is the second time we have used ERG. Last year we had windows installed and were delighted with the work. This time it was roof line and gutters. Everything was done to a very high standard, both the fittings and the two boys that did the work. The whole look of the house has been transformed, so very happy with everything. Even had a gentleman at the door asking who did the work and would we recommend them. Of course we definitely could. Thanks to everyone

High quality work. Superb fit and finish. So very happy with the end result. Totally transformed our home. Can’t recommend enough! We’ll always come to Trademark first when we need any new home improvements!

Top company, great work, great price, great after sales support and really pleased with the results! Highly recommend if you’re in the Reading/Berkshire area.

Really happy with the job Trademark did for my parents house. New UPVC front and back door. Good price, good installers and a great 20 year warranty. Highly recommend!

Having been scammed by a builder a few years ago, I was very cautious about choosing a company to replace my front windows. After doing my research, I contacted several companies for quotes and eventually engaged 5 Star after a very satisfactory consultation /planning meeting whereby I was price matched to a previous quote I was thinking of accepting. The surveyor's visit went without any issues and I was initially given a rough installation date of after Christmas 2024. However, I was contacted by the appointments team to say they could install on 16th and 17th December. The whole installation process went well, with the exception of time keeping on the part of the fitters. I had to call the head office each morning because of them being over 1 hour late. Both times there were acceptable reasons why they were late, but it would have helped this review if this could have been communicated to me in real time - via head office if they didn't have my number, maybe. 5 Star have said they were going to follow this up. Having said that, the installations went well on both days. The Fitters were very friendly and helpful, and worked well to get the job done. Trickle vents needed to be ordered to finish the job , which arrived after Christmas and fitted on time by another team. All admin and office staff have been very supportive throughout. Will recommend his company to friends and family Would definitely have them to do more work here too.

After putting up with a cold, old fashioned and draughty front door for many years, we decided to update our door and chose 5* as we had used them in the past. From the moment that we met the salesman through to the fitting of our door, we were treated with respect and received exceptional service, professionalism and an amazing quality product. The fitter was thorough and professional and left the house in an immaculate condition. The installation was superb in every way and we are more than satisfied with 5* and our new front door.

A very efficient surveying and ordering process with clear paperwork and guidance throughout the experience. All employees arrived at the specified times and carried out their work efficiently. We had a minor problem with the lock which was quickly and efficiently sorted. The employees obviously knew their job and were very thorough in their execution resulting in a pleasing end product.

Great service from start to finish. No pressure selling, just facts and advice. Schedule of works stuck to. Turned up on time and got on with the work. Left the conservatory tidy at the end of the day. Plasterers and electrician provided same service. Good quality work, and we're more than happy with the end product. Would highly recommend this company. Thank you

Well fitted, very little to tidy afterwards, fitters just get in with their work Lovely windows we have purchased two separate lots over two years.

We have just had the best experience with the young man (Ciaran) from ERG windows. What a fantastic job he has done on the new windows and door installation. Cannot praise him enough for his workmanship. He worked like a trooper from beginning to end, turning up early and finishing late. Excellent quality of materials, finished to a very high standard. Bornisketaig, Isle of Skye

Excellent customer service from initial sales contact and survey to installation. All the ERG staff we had contact with seemed to understand the needs of the customer which made everything straightforward and a pleasant experience. In particular, Neil, the installer, is commended for his attitude, his quick and efficient completion of the job, his attention to detail and his pleasant and friendly way of dealing with his customers. We felt that he went the extra mile to ensure that he left no mess and even helped to replace blinds that we had taken down. Although still very new, the windows appear to be very good quality and we look forward to many years of trouble free glazing. We would certainly recommend ERG to others.

Great service from beginning to end & beyond.  Efficient, polite and professional employee’s throughout the Trademark Windows company.  For all appointments everyone arrived on time from the measuring up, to the installation. Excellent quality and installed extremely well.  Careful parking and care of property was second to none, with the home and garden being left spotless, and I’ve been given a 20 year guarantee.  Highly recommended.

Whole experience, from initial survey to installation, was professionally deliver. Our new windows are very well made, highly recommend 5 Star. ⭐⭐⭐️⭐️⭐️

5 Star fitted all my doors, windows and veranda panels and did a fantastic job, all mess cleaned up and removed, absolutely no disruption and finished on time as promised. Worth every one of the 5 stars.

This is the most professional company we've dealt with, every step of the way we were informed of what the next steps were and when they were likely to happen. When it came to installation time we were given timetable of works and they tradespeople stuck to the dates without fail. All the trades involved were efficient and courteous. The final result way exceeds our expectations and would not hesitate to recommend this company.

Great price, good quality windows & door , fitted expertly & quickly. Fitter noticed a fault that I hadn't & faulty part was replaced soon after. I'm well impressed

We ordered an external double glazed rear door ,the service was very good ,firstly with the Senior Designer ,who discussed the request and finally with the installer ,who completed the installation with great ease and professionalism ,the order to completion was very well organised and on time

This is not our first installation from 5 Star. We were thoroughly impressed with the service we received. Although our fitting was delayed due to bad weather we were updated at every point. The fitters arrived on time, were polite, worked well and made very little mess installing the window. Very well pleased.

Really pleased with my new conservatory and porch replacements. Its always a bit worrying when having work done on your property by a company you haven't dealt with before, as you never quite know what you are going to get. But I have to say everyone I met from Eden were just really nice people, and a pleasure to have working on the house, from the surveyors, electrician, plasterer, etc, and particularly the main two fitters who took extra trouble to do a quality job. On some days extra hands were drafted in as required, and everything seemed well organised by the installation team. I even needed to do some work on the house myself while the work was going on, of which they were very accommodating and helpful. All in all a really good experience. Thank you Eden Windows.

From design to installation the experience of using Bon Accord Kitchens was first class. Throughout the design sessions, Danielle's guidance and input made sure we ended up with the dream kitchen we had hoped for. Installation team too couldn't do enough to make sure the end product was 100% delivered to our satisfaction. We are more than delighted with the end product and would thoroughly recommend the Bon Accord Kitchens team.

the service has been excellent from the initial contact through quoting and arriving for the installation. following the installation the clean up left no evidence they had been on site.

I would like to say a big thankyou to all the people involved with my ordering right down to the installation of my windows,the men that came to put my windows in were very friendly and they made the minimum of mess to wich they cleaned up after.the windows look great snd I am so happy I chose 5star.

Quality windows installed by highly competent and friendly staff. Reduction in noise from surrounding area notable. Mechanisms smooth to operate and feel solid. Windows look good and have improved the overall look of the house.  Excellent communication from 5 star throughout. Good customer service. We were kept up to date, details confirmed at each stage throughout. All staff were punctual. Installation team were neat and methodical.  Would definitely use this company again. 

What can l say, it was a pleasure dealing with the very knowlegable members of the team. The showroom is amazing, l did not realise there are so many styles of window to chose from. We made our choice, a day or two later a gentleman came to go through exactly what we wanted, a few days after that another gentleman came to measure up precisely every window. Three/four weeks after our initial visit to the showroom the guys came to change the windows, very pleasent chaps confirmed with us what was the best order to fit the windows. They worked like trojans, first day main bedroom, on suite shower room and bathroom. Second day, both front bedrooms, kitchen 2x windows, Third day lounge window, sun room, and replaced patio doors. The guys made good all around inside and outside the windows/doors. After each day you would not know they had been, got to say these chaps knew there stuff, the original windows were thrown in, the new ones were professionally fitted and adjusted. From the fourth day the difference in the house was noticeable, any wind and the heat used to be sucked out of the windows in no time, not any more. Great job everybody at Premier.

A great experience from start to finish. The salesman came,measured and sent a quote. No pressure, no follow-up calls and hassle. Very competitively priced. Very polite, clean and tidy workmen. A slight issue with the incorrect glass but was very quickly rectified. Overall, completely satisfied. Would highly recommend.

From start to finish the staff at Trademark have been highly professional. Great communication with timings of installation and repeat quotations, when we couldn't make up our minds on which style of window to go for. All elements of the service were well explained. Would definitely use them again.

We originally had our windows done in March and decided to have our patio doors done by Trademark after the good job. Great communication throughout and very happy with the end product. Would recommend!

Professional service on our installation. Very pleased with the result on French doors and window.

We love our new kitchen. The design is beautiful, following our brief perfectly. The installation was most professionally delivered by skilled tradesmen.. My favourite thing, however, is that everything is in just the right place - so well thought out. A dream in which to cook and eat!
