What Our Customers Have Been Saying

Two story house in Northampton. One French door and nine windows including one bay window fitted in 28mm dg uPVC. All done within agreed schedule and budget. We were and continue to be impressed with the professionalism shown from initial quote to installation to follow-up to rectifying any problems arising, which were very minor, indeed. Exceptionally helpful from beginning to date. We were kept informed throughout. All enquiries were dealt with promptly, with courtesy and consideration. No waiting on the line “because all our representatives are busy…” as is only too common these days. Altogether we found Windsor Windows a pleasure to deal with and look forward to place further orders with them. Highly recommended.

Customer in Northamptonshire

We had ten windows, patio doors and a back door fitted in a very cold week in December. From Lee Cross visiting and delivering our quote to the fittings themselves, everything was handled in a helpful, friendly and professional way. The actual fitters kept us informed of what was happening and were cheerful and hardworking. Very little mess was left at the end of each day. We were recommended to Windsor by a friend but did have other quotes which were more expensive and delivered in a far less professional manner than Lee’s. We would have no hesitation in recommending Windsor Windows to anyone.

Customer in Northamptonshire

Windsor have recently completed replacement windows and a conservatory for me and I have been very pleased with the results of both. They were efficient, tidy and excellent value for money. When minor snags developed – as they always do – during the works they offered me options and then got on with resolving the issues quickly. I was kept informed at all stages and all the different tradesmen (electrician, plasterer, groundworks crew etc etc) turned up when they said they would. Even my neighbours have said how respectful they were of the driveway that I share with them as this could have caused problems.

Customer in Northamptonshire

We had a replacement conservatory fitted in May and the work was done by 2 capable and experienced fitters without mess or inconvenience. They met their promised delivery date and the time on site. In September we had Windsor fit a bi-fold door. Again they met their delivery and fitting promises and did an excellent job. We have been very pleased with their work

Customer in Northamptonshire

Had a large patio door fitted by Windsor. After contacting the company Lee Cross visited to measure up and take down our requirements. Within days he hand-delivered a detailed quote which we were very happy to accept – the price was excellent and also the cheapest we had been quoted. The installation team did an excellent job and we couldn’t be happier with the service from start to finish. We highly recommend Windsor Windows.

Roy in Northamptonshire

I cannot fault Windsor windows in any aspect of their work. Of particular note was their conscientious attitude. They were competent, polite and reliable. I would recommend them in all confidence.
