What our customers think...

We recently got new PVC windows from Stephen at Crescent Windows. From initial quote stage right through to fitting, he was so reliable and true to his word. Very clean worker, no mess left, such a great guy to deal with. Would highly recommend. We shopped around, Crescent Windows were by far the best service & best price. We are delighted with them, thanks again.
