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.

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.

⭐⭐⭐️⭐️⭐️

My mouth has dropped reading these reviews because this is not my experience with this company.
And almost all these reviews were done while I was being told by them that they couldn't attend their start dates of the job due to staff illness for over 6 weeks. Something fishy with reviews or companies truthfulness.
Anyway after having 4 months they finally showed up staff reported to me that they had no communication from boss. Boss had no communication with customer me. It's no wonder they fitted the wrong size door even the brothers don't appear to communicate. It was hot and miss that a simple balcony door and 3 cladding boards took over 2 months to finish because they didn't even charge their tools or kept having to leave complete joke no wonder the end result was wrong.

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
