Customer Reviews

Everything went smoothly and very quickly. Clear up of the rooms and outside area the end of the installation was super.

This was the second batch of windows we have had done and as with the first the service was excelent. From the initial sales person through the survey contacts from the officde and finally the install. The first batch were fitted over 15 years ago and are still working perfectly. We would recomend to all.

Very professional, the measurement, what I wanted, the price agreed, and deposit and final price. The installation was clean and easy.

The salesman was not pushy went through the details of the doors etc and gave us a price and said he would leave it with us to decide when ever we wanted. ( I've sold Double glazing products, so I know my stuff about doors and windows etc. and good quality of products) The surveyor came and measured more accurately, which gave us an even better option for one of the doors. The fitter arrived and politely introduced himself as Neil, he made a start getting all fours doors fitted then went round stating the trims etc , he made sure there was dust sheets down where he was working and gave great detail to the finishing touches ( In total it was 1.5 days to fit the four doors)

The men came promptly at the time specified, were polite and answered my questions. They did the work expertly and swiftly and did a great job of clearing up afterwards. They also took time to explain the window fastening. The windows look amazing, such a great improvement and I am very pleased with the result. I would recommend ERG anytime.

From start to finish, the engagement and communication, in person visits/meetings, installation and aftercare has been brilliant. ERG are an organisation that I trust and would recommend to anyone.

Thank you for your kind feedback! We're really pleased to hear you were happy with the efficiency of the service and that everything was resolved quickly under warranty. If you ever need anything else, don’t hesitate to get in touch we are always happy to help.

So delighted with ERG Scotland. Went on holiday and left a key for the installers. They came in and fitted all new windows throughout the house so when we came home, all completed to a fantastic finish. I would never have known they had been there. Thank you to all the staff for a brilliant job. Cannot thank you all enough. 😊😊

We ordered through 5-Star knowing they were local & knowing Ross who works there. Ross helped us tremendously throughout our purchase alongside the installation crew at the time of install. The process took longer than expected but we did order a door to be designed & built & then found it was being built over in Ireland. The wait was, now we have it, well worth it!  Thanks Ross & the whole team.  Always on hand now for any aftercare we may need. 

The team were fantastic and everyone was very helpful. Highly recommend erg the windows looked fantastic and I’m so happy with them. Everyone I spoke to were lovely and never once did I feel pressured into buying anything. The guys who came to fit them did a fantastic job

The work was carried out over five days in March 2026. The first three days was spent removing the existing polycarbonate roof and replacing it with a Livin Roof Utech Panels Aqua Glazing. The next two days involved boarding and plastering the ceiling. The quality of the work and materials used was outstanding and beautifully finished. The fitting team and plasterer were pleasant to have in our home and showed a genuine keenness and concern to get the best result. They are true professionals, very 5 Star quality and value for money.

I can’t praise the window fitters enough very clean workers and appreciate that they considered that I have breathing difficulties and tried to keep doors close as much as possible. Very impressed by how they cleaned up afterwards and never left a mess.

From start to finish 5* windows have been very good, the process could not have gone better. From our first interaction with Mick, who couldn’t have been more helpful to the installation by Lee who was brilliant. I would 100% recommend this company.

Great experience from start to finish. I was kept informed all the way through the process from the initial Sales enquiry to the installation. Installation team was brilliant, exceptional attention to detail. The finish product exceeded our expectations.

From start to finish a first class service

From first going in to the showroom to have a look round to the final installation the service has been excellent. Thanks a lot. Gordon and Alice.

Excellent service from start to finish. From the initial call, quote, survey and installation. Installers were very efficient and tidy. Delighted with the end result.

This is my second time using ERG Scotland. Yesterday the team fitted a new front door and three new windows, to add to my patio door and back door that ERG did a couple of years back. From the initial appointment to completion everything went smoothly. Great workmanship and were noticing the lack of draughts already. Would highly recommend ERG to anyone looking to replace doors and windows. Thanks guys.

Have had windows, doors and roofline all supplied and fitted by ERG. Great service, no hard sales pitch and good communication throughout!

We were very pleased with how the windows looked when the job was completed. Initially after the windows were installed there was a few things that required tidying up but 5 Star soon organised someone to come out and make a snagging list followed by the fitter visiting to sort out the issues and rectify them to our satisfaction.

We had Bi-fold doors supplied and fitted in October 2025 and have to say we are very pleased, they are absolutely stunning. From the initial relaxed chat with Dean in the showroom there is no sales pressure and he was happy to answer any questions we had. The two fitters Dave & Martin were very professional and helpful and a credit to Eden. We have no hesitation in having Eden again for our next project. Thank you Mr Stuart J King

Everything from the initial appointment and quote to completion was faultless. Every email was replied to promptly, the installers were pleasant, tidy and went out of their way to provide the service expected.

Efficient; excellent product; high quality workmanship; good communication re work schedule; friendly service from installers and associates and office staff

The company from start to finish was excellent 👌 the boy that fitted the windows was excellent

Excellent service from placing the order to completion

Great service from start to finish. High quality products. I would highly recommend 5star.

I found ERG very efficient from Quote to fitting. When looking for a new front door ERG were the best value for money, the rep went through the options on what was the best door for our house and was very knowledgeable about all the doors in the catalogue. The engineer who fitted the door was very thorough and made very little mess and made a neat job of fitting the door. The new door has made a big difference to the warmth to the house but not only that the look of the front of the house. ERG have given me a great service and a good quality door at a very reasonable price.

We chose 5 Star as they had carried out work on another property for us. From start to finish the service we received was excellent. From the sales staff to the fitters, our jobs were stress-free. Sales team explained what was available and the cost (No hidden extras). We were given dates for the fitting of the products ( 11 windows followed at a later date by patio doors). The fitters arrived on time on the specified dates, and worker efficiently and professionally with brilliant attention to detail. At the end of each day the site was left clean and tidy. The reason that we mention "Jobs" is because we were so impressed with the initial installation of the windows that we elected to have our patio door replaced at a later date. We have been so impressed by both the service we received and the quality of the products, we would recommend 5 Star to anyone considering replacement windows and doors

The quality of the windows and door is excellent. The process from quotation by Colin to survey by David and support from Caitlin was clear, straightforward and helpful by all involved. Kieran the fitter was polite and helpful and the internal finish he completed was excellent.

From beginning to end all trades were excellent and couldn’t fault them. However what let the Company down was the administration! Booked dates then confirmed different dates. Booking electrician same time as clean down. Clean down only thought they had doors left to clean when in actual fact whole project,  so delayed. If they sort the admin out would be 5*

Very pleased with our new patio doors. They look great, and are exactly what we wanted. Seamless process, from measuring up and quoting to final installation. Lee, the fitter was extremely professional, tidy, efficient has made an excellent job of fitting them for us.

We are in the process of renovation our home in Totalnd and started what I thought would be the dreaded process of finding a com many to do provide a quotation to replace all the doors and windows with new powder coated flush casement aluminium joinery. We ended up nailing it down to two companies, both local and with good reputations, and after meeting both, settled up Jordan to carry out the work. We went to their show room in Newport and were immediately impressed by the friendly reception (Abbie?). We then met Callum, one of the sales chaps who was a total delight and not at all your archetypal double glazing salesman. He was very knowledgeable, gave all the time we needed and took care look to show us all the options in the show room which was hugely helpful as we could see exactly what would be getting. Callum then came out to the house to do a comprehensive survey, again, taking time to answer any questions, put forward suggestions that might help and then went away to work out the quotation. Again, no pressure selling at any point.  We awarded Jordan the contract feeling confident that we would be getting great quality windows and just as importantly, service. This was quickly confirmed when Steve came to do the surveying and has been back a couple of times since to make absolutely sure he was happy with what was being made. We are now very excited about seeing the new doors and windows starting to go in as of the 1st December. Great products, excellent service so far and fair pricing. Oh yes, that reminds me; their price includes the removal and disposal of all the old joinery and doors which is great. Many thanks Callum, Steve, Abie and all at Joedan - we can't wait to see the new joinery going in!

Fantastic service and workmanship from First quote to fitting great price and the work men left the place spotless 

Professional and friendly from start to finish. Our new doors look beautiful and won't hesitate to have you back for the windows.

Everything from the planning to the build and completion has been straightforward and professional. We kept informed about the timings and processes involved at each stage. The finished extension is perfect and the finish immaculate, we are delighted with it!

Very happy with windows first class service from start to finish. The fitter was really good very tidy at his job a asset to your firm. Would recommend ERG to anyone planing new windows.

From initial enquiry, through to survey and installation, we found everyone involved efficient, helpful and professional. We're very pleased with our new back door - no more draughts or struggles opening and closing. We wouldn't hesitate to recommend.

Very high quality doors, workmanship and friendly before and after care! We would definitely recommend them for anyone looking for either doors or windows!

We are just delighted with our conservatory ! All the tradespeople were very professional and the finish is top quality. The time line to completion was well managed by the ERG team and any communication with the company gave quick and helpful responses. Thank you !

Swift work done, staff on site were courteous and efficient. Home is now warmer and more secure following installation of 2 composite doors and 1 patio door.

From the first enquiry. The service from ERG was fast and efficient. I am delighted with my new windows and doors and I recommend ERG to everyone!

From the initial meeting with Bryan to discuss our needs to the follow up calls to ensure we were happy with the products after installation, everything has been seamless and very friendly and professional. I have no hesitation at recommending this company.

We tried several firms in our search for some replacement windows and in the end we liked the approach of Trademark and their products, as seen in their showroom. Not pushy but just a polite, gentle explanation of their products, an approach which went a long way to our decision to go Trademark. In addition, they were very accommodating to our request for different colours internally and externally. The fitters were very efficient, polite and left a very clean site afterwards. After one month, everything is still wprking and looking fine. Very pleased to have chosen Trademark

We absolutely love our new windows and doors. We can already feel the extra warmth and light they bring to our home. The fitters were very professional and considerate. We would definitely recommend Trademark Windows !

What an AAAAmazing job. Oh my word your company products and the team there are truly customer and service driven. First class. First prize. And we are so happy.

Company very helpful helping me to choose which windows, and what type, to be fitted. Kept me informed of the progress of the window production and proposed fitting dates. Fitters were very tidy, efficient and courteous at all times. Would highly recommend ERG.

TradeMark Windows installed a bay window for us, replacing the rotting, single-paned window we had before. The service was quick, the old window was taken away and the area was left tidy. We are happy to use a local provider too.

We approached TradeMark Windows because our nextdoor neighbour had used them and the windows looked amazing on her period property. The service we received from the original quote to instillation, which was less than a month in total, was top notch. My only slight grumble was the amount of broken glass from our old windows that was left in our flower boarders.  Overall though, I would have no reservations with recommending TradeMark Windows and I will use them again for a couple of smaller windows at the back of the property in the future. 

We needed a new window to help accommodate a downstairs toilet and study plus a very small one in our cupboard. When the Surveyor attended he suggested the best approach to make the most of light in the toilet and in my smaller study. The windows were fitted very professionally and with care and we are delighted with the results. We would recommend Trademark and will definitely come back to them when we need more work in the future.

The process was very easy and they were quick to complete the work. There was a small mishap where a bit of the door wasn't attached properly but once we called it was very quickly sorted, so really appreciated that service! Only reason not giving 5 stars was because it had been missed in first instance but as said very quickly rectified and everything else went smoothly keeping 4 stars!

Efficient service from start to finish. Excellent product, very good quality. Fitters quick and hassle free installation.

We had a small issue with a new door that had slipped. I telephoned at 9.00 am and it was fixed the same day! Who could ask for more! Ann Manning

I would definitely recommend Trademark Windows following the installation of our door. Throughout the process we were kept up to date, able to make changes where necessary and now have a modern, stylish front door which has greatly helped with thermal efficiency.

All done in a day without a hitch. The installers were very professional. Couldn't have gone better.

They listened to some specific requirements and met the brief. Adam even sourced a new locking mechanism, which is appreciated. The replacement door look great, I am very pleased. Only minor whinge is the delay on installation, but only a minor moan.

An excellent installation by Amir and Theo. Amir is a true craftsman and ensured that I was happy with every aspect of his work before leaving my house. 

We used ERG to fit new windows and front door. All the workmen from salesperson to fitters were extremely polite, professional and very tidy, would highly recommend this company.

ERG fitted new half glazed back door and 2 new kitchen windows. Great job, completed in 1 day, Looks great, very tidy worker.

Apart from a few initial design issues and subsequent communication issues, the whole process was completed in a generally professional, clean and tidy manner. The tradesman employed were of a high standard with the exception of the electrician who made promises he never kept and appeared unhappy to be working on the project. Initial builder and Plasterer were excellent in their attention to detail and the 5 Star build team were similarly excellent. A clean and tidy work ethic from all.

Amazing service from to finish. Brilliant company and installed by a lovely person,and compliments coming in fast from people walking passed my home

Had a follow up visit to adjust our bifold doors. Very happy with the job. Big compliment to the staff who came 40 miles to do the job. Quick, neat, tidy. Great ambassadors for the company.

We recently had a new patio door fitted by ERG Scotland, and we couldn’t be happier with the result. From start to finish, the service was professional and stress-free. A special mention to Keiran, our fitter, who did an outstanding job — he was punctual, polite, and his attention to detail was excellent. The finish is perfect, and everything was left clean and tidy. Highly recommend ERG for anyone looking for quality workmanship and great customer care.

We initially contacted a few companies to come and quote to replace all of the windows and doors at our property but went with 5 star because the sales approach approach was one of honesty, transparency and zero pressure - some of the other companies who visited tried to put tremendous pressure on us to sign on the dotted line immediately and used all kinds of tactics to try and make the sale. Although the quote was slightly higher, we opted for 5 star because we felt like we could trust them. The scheduling team were professional and helpful and the installation team were great - prompt, tidy and efficient. We’ve only had the windows and doors in for a week, so have not encountered any post installation issues, but I feel confident that if we did or do in the future, they would be handled promptly and efficiently. 

Had 2 new bedroom windows fitted 23rd September, fitter arrived on time, workmanship and finish was excellent. he kept the work area clean throughout and when he left you wouldn't have known he had been, had it not been for 2 new windows. Must apologies for not taking his name else I would have commended him by name, highly recommendable.

Thank you Mick, professional & hassle free from quote, ordering to installation. Previously had extreme issues with another company so was very pleased to have a company with no stress.. 5 * have many options to chose from with great advice and payments options. I'm back again for a new bathroom window due to the satisfaction of my new front door. Would highly recommend 5 * !

A kitchen window was required to replace an earlier installer's 3-pane window, now damaged. An additional opening panel was requested. The agreed price was very reasonable, installation was extremely prompt, courteous and efficient. After a wait for the arrival of a replacement for a faulty window handle the company was totally content to wait for my 'time-away' holiday arrangements. Replacement handle was installed and the engineer took care to adjust the friction within the mechanism to accommodate my wife's now, sadly, limited abilities. A very positive experience.

Initial sales pitch was excellent, helped us design what we could afford , not pushy. Fitters were excellent couldn't fault, minimal disruption and cleared up, good product will be back to add more when we can. Only downside was visit on the installation day from client liason officer who was far too pushy and aggressive and upset some neighbours , apart from that couldnt fault and will use again

I now look at the excellent doors which make me feel more secure, they were also expertly fitted.

Brilliant service from quote to installation and everything between. Quick efficient and no mess. Would use again in a flash if the need arises. Good looking product too. Nothing too much even when it comes to maintenance of products they didn't supply and fit

Very pleased with the whole service from start to finish. We had two excellent fitters who turned up pretty much to the minute and worked closely as a team. We had a new kitchen window, sliding patio doors and a new front door. All work was completed, everything cleaned up and the old items removed by lunch time!!!

I have used ERG twice recently for my properties and on both occasions the service they have given me has been first class. Their quotations have been very competitive, communications have been swift and efficient. And the work was completed on time with no fuss. The staff are very friendly and very knowledgeable and I won't hesitate to use them again.

Couldn’t be happier, the service the quality of the windows, would recommend to others, tied up offer themselves, I recommend 5stars 

All aspects of the job were carried out to a high standard including initial quote, survey and specification, installation and customer service contact. The installation team were very professional,communicated well with us and carried out the job perfectly to meet our requirements and in good time.

From initial enquiry, right up to completion, we found the service first class. All employees were polite, helpful and totally professional. There was straight forward pricing with no pressure. The fitter arrived promptly and worked non stop throughout the 2 days it took to complete the work. Our property was left immaculately tidy both inside and out. Would highly recommend.

Great experience working with Trademark. Salesman was knowledgeable, helpful and offered a lot of advice on our new door. Door delivered and fitted on time. Would highly recommend
