Timber glazing upgrades in Greenwich
If you are looking at Misted Unit Replacement in Greenwich, the timber is only half the decision. You will find mostly Victorian and Edwardian terraces, mansion blocks and post-war infill in this area, and it moves as it ages. high pollution load and sheltered urban humidity is the local complication, and paint failure on south-facing sashes and rot at the bottom rail is what it eventually causes. Our focus on this is swapping the failed unit rather than selling you a whole window.
A surveyor visits first and records the real dimensions, at several points on each opening. Rough dimensions and a couple of photographs are enough for us to price it properly.
A local consideration we always raise: 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.”
Verified client, Greater London“They fitted trickle vents we had not thought about, which stopped the condensation.”

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 if the opening is out of square?
Most older openings are. The survey records the actual dimensions at several points and the unit is manufactured to suit, which is the main reason we survey rather than work from the sizes given over the phone.
How do you handle glazing?
Standard double glazed units for most work, and slim-cavity units where a conservation officer has restricted sightlines. Single glazing with putty lines is available where the consent requires it.
Do you fit, or supply only?
Both. Supply-only is common for trade and contractor clients. For private clients we usually recommend supply and fit, because responsibility for the fit and the finish then sits in one place.
How long does a typical order take?
Most made-to-size orders run six to ten weeks from survey to delivery. Conservation and heavily detailed work can take longer, and we confirm the lead time in writing at quotation rather than leaving it open.
