Customer in Northamptonshire

We recently had a door, window, fascia boards and guttering replaced on our garage and 4 windows (including a bay window) on our house. Lee, Diane and the fitters were both friendly and professional. The fitters arrived on time and all work was completed in 2 days. All the scrap was taken away and everything left very tidy both outside and inside of our house. Very pleased with the service we received and the product and would highly recommend this company.

Customer in Northamptonshire

Windsor’s replaced all our windows and 2 external doors 5 years ago. We were more than happy with the quality and workmanship. So we decided to use them again to replace our fascias guttering and soffits. The fitters were very professional and worked during the hottest week in July. They tided up after themselves. We would recommend Windsor Windows to anyone.

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.

So good we choose them a second time. 6 windows initially on property of non-standard construction – unfazed! professional from survey to completion, efficient courteous, communicative, true to costing, clean and tidy, smart appearance, cannot speak highly enough and will use them ongoing on our renovation. Outstanding.
