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.

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.

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.
