Maintained work undertaken by Andrew and Kieron. Very professional and to a high standard. Definitely have them again. Value for money as well.

Great to hear you're pleased with Andrew and Kieron's work - I'll be sure to pass on your feedback! Thanks for taking the time to leave us a review.
So customer focused.
Customer Service
I needed two sets of handles for my French doors. I telephoned the number of the company at 11.00 am and spoke to Mr Cavan Williams. He contacted Andrew one of his fitters whom was out doing some work for a customer. Andrew called to my property on the way back to measure the size of the handles. The handles were not in stock but the company sourced the required handles in Cardiff, collected them, and fitted them by 2.30pm. The point I would like to make is that the company treated me as though I was giving them a big money job, but of course it was a small job to them. They were very courteous, and nothing was too much trouble for them. This is great to see in a very well respected Welsh company.

Very satisfied customer
Customer Service
We had a new front door fitted. From first contact to job completion we had no problem and had some very helpful advice from Caven the company rep on security and fittings. Nathan the installer did a great job and cleaned up well when finished.

New door
Customer Service
Andy and Kieron did an excellent job of fitting the new door. They were efficient and got to with the job in spite of appalling weather conditions. They cleaned up before leaving. Explained the workings of the new locks. A good job done as always with Welsh Window Systems. Recommend!
