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!

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.
