Report
We've had Alan round to do numerous jobs on our current property and also on our previous one. We've had windows, doors, a conservatory and also soffits and fascias done over the years. I can't recommend Alan Maris Windows enough and a number of our neighbours have also had work done too. Alan is professional, knows his stuff and guides you through the entire process with ease. His team, Dean & Dan, are both hard working and leave things clean and tidy. I wouldn't hesitate contacting Alan for any future jobs.

Report
I can't recommend these guys highly enough. Excellent quality products, workmanship and customer service from start to finish. I had a complete fit out done - doors, windows, French doors and a conservatory and it was all superb. They'll be the first and only firm I call in the future.

Report
Just had 10 windows, 2 composite doors and a sliding patio door. Excellent service from the quote right through to the finished product. The fitters were here early everyday, worked hard all day not even pausing for lunch. Price wise, excellent. Cheaper than at least three other local firms. All in all a very friendly and trust worthy firm that I would highly recommend and would use again. Many thanks to Alan, Dean and Dan.
