Fabulous job
Customer Service
I have used Welsh Window Systems in the past and not been disappointed. Today, Nathan and Jacob arrived on time to fit my new tilt and turn window which features an internal blind. They were done in a morning and left the place shipshape when finished. The new window was installed in my study and they covered my computer/printers/scanners to protect from dust. To say I’m delighted with the job is an understatement - it is fabulous. Cavan Sullivan your boys did you proud. Thanks so much.

Thankyou so much for leaving a detailed review for us. I've passed on your feedback to both Nathan and Jacob. The internal blinds are a popular choice nowadays. Thankyou again for taking the time to leave feedback
Did exactly what they promised when they promised. Result!
Customer Service
Andrew and Jacob fitted a new downstairs window for me. The time from ordering to fitting was about five weeks as advised which was much quicker than some of the other quotes I had and was very pleased with the finished result. The were very friendly, worked efficiently and went the extra mile making sure the window was gleaming when they finished and even cleaning the window next to it which looked filthy in comparison. Great customer service and they seemed to be experienced and hard working. Would definitely use them again, not the cheapest quote I had but far from the most expensive but they were able to do the job relatively quickly and made everything straightforward.

Thankyou very much for taking the time to leave us such a detailed review Janice! I've passed your feedback on to both Andrew and Jacob :) . We pride ourselves on the high standard of work and I am very glad you're pleased with the whole experience, we always try to go the extra mile where possible. We may not be the cheapest, but as you said we are far from the most expensive - we refuse to use any products that aren't up to our high standard expectations and this obviously comes with a cost. Thankyou again for your feedback :)
Excellent work
Customer Service
Andrew and Jacob finished fitting the last of 3 windows for me today. They were prompt, efficient, very polite and tidied up afterwards. I am really pleased with the windows and would recommend Welsh Windows. I will definitely use them again.

Excellent fast work
Customer Service
One of my windows was broken and needed to be replaced. After some unavoidable delays caused by the lockdown, Cavan replied to me as soon as possible, and came around either later that same day or the day after (I can't remember which). He quoted a very reasonable price, and made no attempt to pressure me into replacing another window which, though fine and unbroken, doesn't match the others around it. His men came to replace it as soon as the glass came in. They arrived, I showed them in, and then sat down briefly to finish an email I'd been writing when they came, while they got straight on with the job. I still hadn't finished the email by the time they'd completed the job. Splendid work, and I'll definitely come back to them if ever I need more glazing work.

Replace window insets
Customer Service
I neede the double glazing replaced in several windows that had gone cloudy. The price was good. No attempt was made to push me beyond what I wanted. No tedious sales spiel. The fitters arrived slightly early, got on with the work, which was done quickly and tidily. No mess, no damage. The whole process was quick and painless. People friendly and efficient.

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.
