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.

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.
