 Trustindex verifies that the original source of the review is Google. We recently had our shopfront replaced by Doors Windows London Ltd  which included bespoke hardwood windows and two external doors.
The project was quite specific and involved overseas manufacturing, so a few initial adjustments were expected with such custom work. He addressed every concern promptly and genuinely went above and beyond to ensure everything was finished to the right standard
Thomas the owner Communication throughout is good and we were always kept informed of stages of work.
The finished result looks fantastic the hardwood detailing is beautiful and the doors feel solid and high quality.

Thank you to Thomas and the team for delivering a shopfront that we and our customers absolutely love!

 Trustindex verifies that the original source of the review is Google. I could not recommend Doors Windows more highly. Our two new windows were installed by a very helpful, quick and efficient team, who were immaculate in their friendliness, preparation, execution and especially tidying up. The windows look very good quality and we are extremely pleased. Ten stars.
