Timber glazing upgrades in Wandsworth
If you are looking at Trickle Vents and Ventilation in Wandsworth, the timber is only half the decision. 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 exposure here is high pollution load and sheltered urban humidity, which is exactly the condition that causes paint failure on south-facing sashes and rot at the bottom rail. What we concentrate on is keeping background ventilation compliant once you seal a house up.
We check on site before committing anything to the saw, and we query what does not add up. Rough dimensions and a couple of photographs are enough for us to price it properly.
One local point to factor in: 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.”

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.
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.
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.
Do you deliver nationwide?
Yes, we deliver across England, Wales and Scotland. Delivery is priced into the quotation so there is no separate charge added later.
Can you match an existing profile?
Yes. If you can supply a section, a photograph with a rule in shot, or an old unit, we can replicate the profile. For conservation work this is usually the condition the planning officer will apply.
