Timber glazing upgrades in Hounslow
What makes Thermal Survey work in Hounslow is usually invisible once it is finished. Given the Victorian and Edwardian terraces, mansion blocks and post-war infill that dominates locally, standard sizes are the exception not the rule. What accelerates it is high pollution load and sheltered urban humidity, and paint failure on south-facing sashes and rot at the bottom rail follows sooner than owners expect. The value is in measuring where heat is going before anyone recommends a spend, not in the timber bill.
A surveyor visits first and records the real dimensions, at several points on each opening. Photographs and approximate sizes are all we need to start.
Local factor worth flagging early: 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.”

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.
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.
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.
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.
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.
