Great product and very keenly priced
Great product and very keenly priced. Fitters turned up on time and did a very professional job. A bit untidy but given all windows and doors were being replaced, a minor issue. Brilliant service all round, from sales to fitting, and I would highly recommend them.
Excellent work all round
Excellent price, local company to us in the Milton Keynes area and the quality of products and installation was excellent. I would highly commend the company if you're looking for double glazing.
New Roof fitted to our Conservatory…
We recently had a new roof fitted to our conservatory by Win-dor. The two men, turned up as promised, with all the necessary materials to complete the job. They were both excellent workers, very pleasant, very skilled, very tidy and very energetic. They completed the job in less than the advised timescale, leaving my wife and I more than totally satisfied with the experience and really pleased with the result
Fantastic service and products with prices that are right!
This review is written by a very happy and highly satisfied customer!
Where do I start?…There was so much attention to detail from everyone who helped us to fit our new front door, French door and kitchen window; even to the aftercare where we had some permanent ink marked on the door frame, which was removed quickly.
Michael, our trusted fitter worked conscientiously, professionally and patiently despite being constantly distracted by my 4 yr old nephew who kept questioning him ‘what are you doing?😂
The products are excellent. Very sturdy and very well made and perfectly fitted. I can’t fault it.
Bobby was also amazing! She contacted me immediately when the supplier couldn’t provide our chosen glass panels for our front door. Instead, she patiently and reassuringly that if we didn’t like our second/reselected choice then they would come and change it further down the line. Plus, they gave us a goodwill voucher of £50; fab to help reduce our final bill!
If you are looking for a trusted double glazing company with an excellent choice of well made products, that are reliable and has outstanding customer support and care then choose Win-dor!
Solid roof on conservatory
We first used Astraseal/Win-Dor 1990. Since then we have used them many times the last to put a solid roof on the conservatory. The tradesmen all worked to a very high standard. The were very tidy and kept us informed of everything.

Had a new front door and our conservatory converted to become a room! Really pleased with end results and would use win-dor again!
Good service, speedy installation
We were very impressed with the speed at which a surveyor attended and the fairly short wait for installation. Windows are very nice looking and effective.

They were excellent at there job they were prompt and I would recommend you to friends and family they were polite and they got on with their job money well spent if there were any problems they would come out straight away.
We love our new conservatory
We love our new conservatory. After replacing all our windows and doors a few years ago Win-Dor was our go to, to replace the old conservatory. A great job once more, many thanks. Geoff & Maria Matthews Aylesbury.
Can’t be trusted to honour their guarantee
Can’t be trusted to honour their guarantee. Conservatories need blinds, they’re far too cold without them quite contrary to the sales pitch about the latest glass.
Apparently, in spite of repeated requests to provide evidence in the contract, fitting blinds will invalidate your guarantee.
Quite unrelated to the conservatory (and hence any issues around blinds) the front door that was fitted at the same time has white patches in the brown facing. The MD refuses to engage to resolve the cause. So the rot starts at the top.
Really pleased with the service we…
Really pleased with the service we received when replacing all the windows and doors when renovating our house.
From the excellent pre instalment survey to the installation (and follow up to do a a little bit of snagging) the service was superb. Really good. thank you
Highly recommended
I would highly recommend Windor. The whole process was smooth from choosing the windows to the final product installed. I was kept up to date throughout and all timescales were kept to. The fitters were extremely professional and did a superb job installing the windows and doors. I am very happy with the end result. Very competitive price too 🙂

My apologies this is the correct
Company:
Win Dor 450 Delta Avenue
Brea, CA 92821
If it was possible this company would get ZERO! In 2014 our Association hired Win Dor to install windows and sliding doors in 25 units. Homeowners after about 2 years started experiencing water intrusion and other issues with their windows and doors. Trying to get Win Dor to resolve the issue is still an ongoing battle. After the recent deluge homeowners are experiencing more water intrusion. Emailed and left messages and am still waiting for a response! Their “Warranty” is a joke.
Also they had to come back and redo all the interior windows in our complex because they did not follow the existing city codes when they installed the windows! DO NOT HIRE THIS COMPANY!!!!!!

Excellent work
We had all our windows replaced in March 23 from wooden windows to PVC.
The 2 men that replaced our windows were excellent, very quick and efficient with no mess to tidy up. Customer service very helpful and easy to contact. We would Highly recommend this company, excellent work. A big thankyou to Phil and his colleague for excellent work.
Hid shoddy work then unwilling to correct it
Windows were replaced successfully. Some time later, the curtain rail fell off, so we tried to re-fix it. It became clear there was nothing to fix it to, because there was a very large void over the top of the new windows, big enough for more than 5 bricks, the full thickness of the external wall. This allows cold air and sound to come in and is, we understand, quite unprofessional and contrary to Building Regulations.
The managing director confirmed the company's view that they ‘had not made anything worse’ and that a large void over the top of a window is quite acceptable. He said it would be the same with the other windows in the house. Other employees of WIN-DOR said they thought this an unreasonable view but were overruled and unable to help us.
The company was completely disinterested in sorting out the problem, sadly.

Reply from Win-Dor
Don't bother, they didn't
The rep (and I use that term very loosely) attended as arranged, but couldn't/wouldn't answer questions about the products, saying repeatedly "it'll all be in the email". He then patronised my wife by telling her to "sit and read the catalogue, whilst we go around the house" (her house too chap!), then after writing down the measurements, departed promising we'd receive his quote by email by the weekend (2 days). That was 9 days ago and clearly he has no intention of supplying the quote. Consequently we've taken our rather sizeable order elsewhere to a company with a professional outlook, rather than a 70's approach. Based on this dour experience of Win-Dor my advice is don't waste your time on these time-wasters.
UPDATE: Instead of replying to my review like most decent companies would, Win-Dor reinforced their appalling lack of customer care by griping about me using an abbreviated first name of the dinosaur who visited us. They are more concerned about a slight transgression on my part regarding Trustpilot's terms of use than providing an explanation or, heaven forbid, apology for his behaviour.
Very friendly staff and fitters
Very friendly staff and fitters. My windows were rather complex which they didn't realise until they had taken the old ones out. They came back and resolved all the issues promptly. I can highly recommend. The windows are lovely. Will be getting my doors done soon through them too! :)
Highly recommend
We’ve been a satisfied customer of Windor for over 10 years, initially having a conservatory fitted and most recently a composite door, French doors and windows in my new home.
The service from start to finish is always excellent. Andrew in the showroom is great, knowledgable on products and provides a good value quote from the outset. Ian the surveyor knows his stuff and the fitters take pride in their work, are efficient and tidy. The communication from office staff is great in keeping you up to date with timelines.
The measure of a good company is their aftersales service once they’ve got your money! Win-dor have always been great in resolving the minor issues I’ve experienced. Within a couple of days my composite door needed a slight adjustment and a fitter arrived the same day to resolve, which was beyond my expectations.
I highly recommend and personally wouldn’t go anywhere else.
New Windows and Door
The whole process has been very professional and personal, from picking our Windows and Door with Andrew in Sales, to the surveyor measuring up, to the installation team. The products are of a high quality. We would definitely recommend or use Win-Dor again
New Windows and Conservatory.
Had all windows done and new conservatory fitted on our new property. After a great job done on our conservatory on our last house by Windor. Andrew the salesman is great and not pushy at all. No issues to date and very happy with the quality of the product again. Would recommend this company and will use them again if we ever move again.
