"We've used Win-Dor to replace almost every window and door in our house over two separate jobs, and we've been completely happy with them. The price whilst not the absolute cheapest we were quoted, was however competitive, and given that their products appeared to be of a higher quality, we went with them.

The windows and doors were all delivered very quickly given the size of the job, and the teams of installers were courteous, clean and efficient. We had an extremely small number of minor (really minor!) snags to put right at the end of the job, which were sorted out in no time.

A few months after the initial job, a couple of the doors began to rub very slightly. One quick call to our sales rep later, and an installer was back within a couple of days to make minor adjustments to correct them.

It's been around 3 years since the initial part of the job was completed, and over a year since the second phase was also done, and we couldn't be happier with our doors and windows. We'd highly recommend Win-Dor to anyone, and have already given them at least three further jobs through word-of-mouth recommendation."

"The whole installation of our conservatory was handled professionally from the order to the final product. The order and any questions we had in the beginning were all answered reassuringly. The men who did the base for the conservatory were punctual and worked very hard all week. The rest of the installation followed for the majority smoothly. We encountered one problem during the final building of the top, but it was quickly corrected only causing a weeks delay. All the men working at our property were courteous and helpful including the follow on jobs after it was built like the electrics, floor tiles etc. The ladies in the office were very helpful when I needed any assistance and everyone was flexible with dates to fit in with us. I did spend quite a bit of time at the property whilst the conservatory was being built, which did assist if there were any questions during the build. I had previously had windows and doors installed by Astraseal and my Parents had done the same, so we were familiar with the company as had previously done our homework and read reviews."

"If you are unsure about exactly what you want - then visit the showroom where really sound advice is provided. Often you will consider a product that you may not have first thought was suitable. Nice, friendly, customer focused service with a product that perfectly fits the bill. Two years after my conservatory was built - I knew the best place to go when deciding on some new doors. Highly recommended for overall service and price."

19th February 2015

"After looking around the market for all new windows and doors, we found win-dor offered exactly the products we wanted at a very competitive price, the sales man was very helpful in finding information out for us and coming back to us quickly.

The Install was easy with minimal fuss and disruption, we had a slight delay on part of the install due to a member of the team being off ill, this was sorted within a day. The only time we had to call customer service was when a lock failed on the front door so we couldn’t unlock from the outside. This was quickly fixed and switched out by the warranty works team.

Would Happily recommend Win-dor to anybody looking for replacement windows and doors."

"The window fitters who installed our new windows, French doors and front door were polite, courteous and punctual and worked extremely hard – the old windows did not want to come out – it was very cold weather – it was not an easy job. Their work was at the highest standard. They tidied up all the mess and didn’t cause any damage to the walls, tiles or anywhere!

Please say a huge thank you to the guys for us and tell them they were a real credit to the company and the most professional team of window and door fitters we could have wished for."
