Just had a number of doors and windows replaced by Square Deals and would highly recommend. From the original quotation they were informative and polite, with no hard-selling. They came back to me with a decent price (not the cheapest quote I had but you get what you pay for imo). Come installation the team were polite, kept me informed and when a couple of issues came up with a missing lintel they were quick to get a plan in place for the brickwork and lintel replacement.

At handback I've been given all my guarantee paperwork and was talked through all the features and given advice on how to look after everything. Overall a very positive experience and would use them again.

I had all new windows and doors fitted in the house. The while process from ordering to fitting was smooth and communication was great. The fitters were very friendly, efficient and accommodating. Perfect job. I would definitely recommend.

We had all of our windows replaced, and our front and back doors - it has transformed the house and we are so pleased! Square Deals were very accommodating of our requests, and happy to advise on things we weren't sure about such as opting for sash windows to stay in keeping with the traditional look of the house (definitely the right choice!). The team were friendly, polite, tidied up after themselves and most importantly did a great job. All the work was completed in good time and at the agreed price - we'd definitely recommend Square Deals.

Just had new windows and a door fitted and we are so pleased with them. The fitters were wonderful. Wouldn't hesitate to recommend square deals for a first class service from start to finish.
