After having recommendation from our next door neighbours we went with Durham Window & Door Centre to have our front and back doors replaced. I could not have been happier with the quality of work and the finished results

I am more than happy with the quality of work and product. Friendly and helpful gent - no issues with workmanship. I am tough to please and expect high standards of workmanship but I give credit where credit is due.

I've just had a new double glazed window unit fitted. Mark couldn't have been more helpful. He did a great job, very quick with no mess and really pleasant. Would highly recommend

We had a lot of silly quotes from various conservatory companies then I finally came across Durham Window and Doors, they came up with the lowest prices and I must say I am over the moon with my new conservatory. I will certainly use them again for future work
