"Win-Dor , in addition to offering a very competitive price, were prompt and efficient throughout the quotation and survey processes. The windows were available within a few weeks and were a perfect fit. The installers arrived on time and well prepared; they completed their work quickly, cleanly and with attention to detail. They were happy to carry out minor adjustments and maintenance to windows previously installed by Win-Dor 9 years ago. This is the second we time I have used the company and again I would not hesitate to recommend them."

"'Last week twelve of our windows were replaced over three days by Rob and Nick. We would like you to know from a customer perspective how fabulous these two men were. They arrived on time and worked well together fitting the windows calmly and professionally. At all times they were polite, well-mannered and respected the fact they were working in a customer’s home."

"As you are aware the quality of any product can be overlooked if a customer has a bad experience. We will happily recommend your installation team and we hope the windows meet the same high standard. Please pass on our thanks"

"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."

"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."

...The windows had been replaced and there was no mess and the job had been completed excellently. We had two of your building workers. Both were friendly, polite and very professional.
The plasterer was in freezing conditions but worked hard all day and did an excellent job.

...We have had an excellent service from you."

"I am writing to thank you all at Astraseal/Win-dor for a job very well done. We are pleased we can be out and about in our conservatory – it is everything we had hoped for and it will make a great difference to our retirement years. The design is ideal. The builders, fitters and tradesmen were all hardworking, expert, friendly and considerate and a pleasure to have around. Your attention to detail and finishing touches went beyond what the call of duty and showed a perfectionist attitude."

Thank you Win-Dor for making the proceedings painless and stress free. I will be recommending your company to my friends etc."
