 Trustindex verifies that the original source of the review is Google. These guys reviewed all the sash windows in our town house, and were really honest in repairing what ones could be saved (to a very high standard), and only replacing what was absolutely necessary, with bespoke windows they make themselves. The replacement windows were also extremely good quality and fitted with no fuss or mess once they had left. All this at significantly less cost than every other quote we'd had, from companies who all flatly refused to do any repairs and would only replace. Great service and fantastic craftmanship, at a very decent price.

 Trustindex verifies that the original source of the review is Google. A family member recommended Simon at Sash Works to make and install new sash windows in a flat in a conservation area in Muswell Hill. Simon was efficient and realistic in all the dealings I had with him and totally reliable from first assessments to final installation. He did what he said he'd do, was accurate with his advice and timings, and always picked up the phone. The price was cost effective and on a par with other quotes and the finished windows are beautiful. He also helped source scaffolding for the installation. Very good service.
