Fantastic service and products from Welsh Window Systems. We had patio doors removed and fitted, front door bricked up and a new door put in a different position. They did it all on time and to agreed budgets. Infact they exceeded our expectations in their approach, care and workmanship. They were so tidy and when it was all done everything was left immaculate. I can't recommend them enough. Cavan did our original quotation and Nathan, Kieran, Jacob and Andrew came to do the work. All were so friendly and their attention to detail amazed us. Thank you.

After reading their reviews here on Which trusted traders we contacted WWS to get a quote for 6 windows plus a new front door. Cavan called to our home and we explained what we were after. We found what we wanted and Nathan called and took all the measurements etc. Andrew and Jacob were responsible for the fitting. These guys were all punctual, polite and respectfully of both property and possessions. During the removal of the old and then the fitting of the new every care was taken to ensure that mess etc was kept to a minimum. Dust sheets covered all our floors/carpets and what little mess they did make was quickly cleaned. Any fittings such as blinds were removed and replaced with care and attention and the guys were courteous and polite throughout. My wife and I are both delighted with our new windows and door and likewise with the service we received from Welsh Window Systems and have no hesitation in recommending them to anyone looking to get new windows or doors.

This is the second time we have used Cavan and his team and once again are delighted. No job is too small for them and we were quoted the lowest price available but chose a higher specification of glass. Andrew and Kieran arrived within an hour of the quoted start time and were quick, professional and friendly. We were particularly impressed by how much they tidied up as the job proceeded. We are very happy with the result.

Cavan and Nathan run a very tight ship, from the scaffolders, fitters, electrician, plasterer and delivery of timber roof structure and upvc, right through to completion. The boys are prompt, courteous and experts in their fields. Each stage was co-ordinated to ensure the smooth running of the jobs to be completed ie: Roof and walls prepared...electrician arrived, electrics completed, plasterer arrived and everyone observed Covid regulations at all times. Cavan is extremely knowledgeable in his field and gave us excellent advice throughout. The boys work in harmony and cleaned up every night in preparation for the next day. There were no hidden costs or glitches and the roof has transformed our home - not only does it look amazing but has warmed up the house and created an all year round. living space. Thank you Cavan, Nathan, Jacob and Andrew.

Conservatory roof replacement

This is the second time I have used Welsh Windows. Last year I had some bedroom windows replaced. They did such a great job, I had them here again to replace my polycarbonate conservatory roof. They have done a brilliant job! The roof is now a solid tiled one with glass panels down each side. The difference inside and out is superb. It is now, not a conservatory, but an extension to our home. The ceiling is plastered and has lights inset and also around the edge in the soffit detail around the top of the windows. Which is lovely. As usual the guys were great, especially with the Covid issue etc. Cleaning up after themselves and I have no qualms about recommending Welsh Windows. I will certainly be using them again in the future to replace other windows too. The price was very fair, and they always go the extra mile to make sure everything is completed to the best of their ability, like for instance, adding insulation where none was present in the existing structure. Nothing is too much trouble. Which is very reassuring indeed.

I had a few quotes for replacing three windows and a set of french doors in my barn conversion. Cavan was not the cheapest quote, but he went the extra mile in attending the home and explaining the type of windows he recommended and was totally upfront about the difficulties the firm was having sourcing their windows due to Covid19. As soon as the windows were available an appointment was made to fit them. The receptionist on the phone was very friendly. The fitter, Nathan I believe, was cheerful and friendly and protected everything with sheets and cleaned up afterwards. The windows look great and work really well and I am so pleased with them. Nathan demonstrated the clever mechanism which makes cleaning the windows upstairs possible. Great company, great windows, great workmanship. Well done!

Thoroughly good company, good customer service, competitive quote. This is the second time I have used this company, they turned up on time, completed the job with minimum fuss and cleaned as they worked, showed me how to use the mechanisms and added a final clean before they went. Excellent workmanship. Well done Nathan, Jacob, Kieran and Andrew and of course Cavan and Gaynor.

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.
