Timber glazing upgrades in Hackney
The Retrofit Double Glazing we make for Hackney is set out from a survey, not a size chart. You will find mostly Victorian and Edwardian terraces, mansion blocks and post-war infill in this area, and it moves as it ages. The other factor is high pollution load and sheltered urban humidity, which is why paint failure on south-facing sashes and rot at the bottom rail is the most common reason people call us. The value is in reworking the rebate so a sealed unit fits without bulking the section, not in the timber bill.
Manufacture only starts once the survey figures are agreed with you in writing. Rough dimensions and a couple of photographs are enough for us to price it properly.
A detail specific to this area: large numbers of properties sit in conservation areas with like-for-like replacement conditions.

“The survey showed most of the loss was around the frames, not through the glass at all.”
Verified client, Greater London“Half the cost of replacement and the rooms hold heat noticeably better.”

Is the timber certified?
All our stock is FSC certified and chain-of-custody documentation is supplied with the order, which most main contractors and specifiers now require for their records.
What guarantee do you provide?
Ten years on workmanship, covering manufacture and the factory-applied finish. Where we install, the installation is covered too. It is issued in writing with the handover paperwork.
Can you work on a listed building?
Yes, and a significant share of our work is listed or conservation area. We can supply drawings and section details to support a listed building consent or planning application, though the consent itself remains the owner's responsibility.
Will the finish need maintaining?
A factory-applied microporous finish typically needs inspection every three to five years, sooner on exposed coastal elevations. Maintaining it is far cheaper than letting a coating fail and the timber take up water.
Can you price from drawings?
Yes. Send a drawing set or a schedule and we will price against it. If anything is ambiguous we will query it before quoting rather than assume and reprice later.
