Timber glazing upgrades in Waltham Forest
Nothing about Misted Unit Replacement in Waltham Forest is settled until someone has been on site. The building stock is Victorian and Edwardian terraces, mansion blocks and post-war infill, so we expect variation before we ever pick up a tape. The weather does the rest: high pollution load and sheltered urban humidity here, and paint failure on south-facing sashes and rot at the bottom rail as the predictable result. Where we put the effort is swapping the failed unit rather than selling you a whole window.
We survey before anything is cut, so the schedule reflects the opening as built rather than as drawn. Send what you have, even if it is only a phone photo, and we will take it from there.
Bear in mind for 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.”
Verified client, Greater London“They fitted trickle vents we had not thought about, which stopped the condensation.”

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.
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.
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.
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.
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.
