Highlights
"Nice work. Dulwich Sash discussed what we wanted and talked through options until the brief was clear. Then they took measurements, made the doors and surround offsite, removed the old material and fitted the new. The fit is good, the colour right, and the work neat and tidy. Communication was good, with post-installation questions satisfactorily answered. Some snagging was needed, including adjusting hinges for a less clunky close; this was done promptly. A 10-year guarantee, including paintwork, is very welcome. We feel we've got what we paid for - and neighbours are impressed!"
"Great work, windows draught-proofed to high standard. Eight large sash windows completed within a week."

Official checkOn the public register
Why this helps you judge trust: this trader is linked to a registered company with named people who are legally accountable for it, on an official register anyone can check — a layer of accountability an unregistered trader doesn't offer. Around 9 years on the register also points to an established business rather than a brand-new one.
