As soon as I rang Welsh Windows, they were very helpful. Someone came out very quickly to inspect and order parts - gave me a price soon after and came today as promised. Can't fault anything!

Thankyou for your feedback Margaret. Much appreciated taking the time to leave a review.
Excellent job
Customer Service
Very pleased with Welsh Windows. When the fitters arrived they were very polite. They explained the fitting process and laid down dust sheets. The job was carried out quickly and with no mess. When there was an issue with one of the parts, the boss came to explain the problem and told us what he was going to do to solve it. The company had to replace a bespoke piece of framework with no extra cost to us. Excellent service, quality products, good value for money.

Good work, done fast
Customer Service
The fault that was causing the doors to stick were readily identified and the doors were repacked and adjusted. Both doors now open and close properly.

Great job

Polite, clean and tidy plus great windows and doors fitted. Cavan gave us really good advice before hand and we took on board all his suggestions which we are extremely pleased with. Now going back to Cavan to replace all the Fascia's and soffits. A great company..

Fantastic - New Lightweight Tiled Conservatory Roof.
Customer Service
Having used Welsh Window Systems a number of times in the past, they were our first choice when it came to replacing our polycarbonate conservatory roof with one of the new lightweight tiled varieties. The whole project was professionally handled from start to finish by Cavan and his team of fitters, who were friendly, efficient and well mannered. The price was competitive and Cavan's extensive knowledge of the product was reassuring when making our choices. The end result has transformed our conservatory into a living space that can be used all year round, as well as looking amazing! We cannot believe the difference the roof has made to the warmth of the house and for the first time we have been able to spend the whole winter in our conservatory....previously a no-go area at this time of the year! I would totally recommend Welsh Window Systems, their products and their team for any future works. Many thanks to Cavan and the team for a job well done.

Efficient service
Customer Service
This was a small job, but it was treated with as much care as if it had been a large order. Initial contact was made promptly and the work was done a week later. Andrew the fitter did a clean and tidy job and we are delighted with the results.
