Highlights
“Had a couple of different issues with 2 windows, the guys came out and had a look. Was then provided with a quote to fit new hinges and locking mechanism aswell as reseal the outside. They then came out and completed the work when they said they would and everything works great now. Couldn't say anything bad at all, I appreciate the work completed”
“Excellent service from first contact to completion of work. I would highly recommend. We were having some issues with our existing door. On the same day I submitted a enquiry the team were at my house, assessing the door. It became clear that the door needed replaced but more than that the team took the time to make a temporary repair to ensure we could use and securely lock the existing door in the meantime. I received electronic links to brochures later the same day. My wife and I reviewed and made a couple of preferred choices. We received quotes for these promptly, enabling us to place an order within days of the initial visit. The team arrived promptly at the arranged time to fit the door. They were very thorough and ensured the perfect fit and that we could operate easily. We are delighted with the final product and service received. Wilz Windows will be our go to supplier for any future window or door needs.”
Detailed reviews
I have used this company a few times and always found them to provide excellent service. 100% recommend them.
Very efficient and quick service to replace a broken pane. Good price too.
We had a broken window in out flat in Glasgow. As it was an unusual design and had to fit with the colour scheme of the flat it would have cost us a fortune to replace it but Wilz Windows managed to repair it for us for a fraction of the cost. They put a temporary repair in which worked well u til they could source a part ( not easy as the windows were old and of German manufacture). They came when they said they would, repaired the window and it all works well. Totally recommend them!
Really impressed from start to finish. The initial quote process and measurements were quick and easy. We'd never had windows fitted before, so we had questions and things we weren't sure about, but Will gave us excellent advice and made sure we felt comfortable with all the decisions throughout. Everyone was friendly, professional and obviously cared about doing a great job. We had 9 windows fitted and it's made a massive difference in terms of noise reduction and keeping the heat in. Excellent value and would highly recommend!
The guys had a bit of bother refitting the windows after repair, but they are quite old windows though. Got everything done in the end, so great job.

From start to finish this company was great! The windows they fitted are fabulous and they were so helpful and friendly. No mess left behind and I got a follow up call checking that I was pleased with their work. 5 star service!
I have used this company because of it excellent work done on time well mannered staff so helpful with advice customers always come first so friendly when arranging appointments always works with their customers l be using this company again on my next home improvement
The Wilz team came round to reseal and refit my windows and balcony doors in my flat. They identified the issues, explained what it was and how to resolve, and then proved their success. Two brilliant tradesmen, very glad I reached out.
We had all the windows replaced at our home. The windows are excellent as we're the fitters. Punctual, worked non stop and left the house in a very clean condition once they were finished. We're delighted with the results and the cost and would definitely recommend to friends and family. Delighted
I am a returning customer and have used Wilz for a few times. Always fast to resolve problem. will definitely return. thanks again.
Absolutly delighted with the prompt service from Wilz Windows. Helped us out during the recent storm by facetiming us and came and repaired our window to make it safe and secure. Definitely recommend them.
Amazing work - would fully recommend. The team were in and out in less than a day and were very polite. Did a great job on the windows on the third floor tenement. Thank you!
Contacted Wilz Windows and Doors for a quote on a new living room window. The whole service start to finish was very efficient and professional. The window was installed today and looks amazing! Definitely recommend Wilz Windows and Doors.

Your own checks
What to check before you hire
Worth checking yourself
Always confirm credentials and quotes with the business directly before hiring.
Be wary of high-pressure 'today-only' discounts and a salesperson who won't leave. A reputable window or door firm gives you a written, itemised quote you can take away and compare against others.
Never pay the full price up front; a modest deposit with the balance on completion is normal. Ask what deposit protection or insurance-backed guarantee you get if the firm stops trading before fitting.
Get the specification in writing (frame material, the glazing units and their energy rating, and any trickle vents) so you can check you got what you paid for.
