Timber glazing upgrades in Malmesbury
There is no standard version of Thermal Survey in Malmesbury, which is rather the point. You are mostly dealing with chalk-downland cob and thatch, Bath stone terraces and garrison housing around here, so openings vary more than people expect. exposed downland wind with driving rain is the local complication, and wind-driven water forced past worn weatherseals is what it eventually causes. What you are paying for is measuring where heat is going before anyone recommends a spend.
We would rather spend an hour surveying than a week correcting. Tell us what you are working with and we will put a fixed figure in writing.
Worth knowing locally: cob and thatch properties need breathable finishes rather than film-forming coatings.

“The survey showed most of the loss was around the frames, not through the glass at all.”

Verified client, Wiltshire“They fitted trickle vents we had not thought about, which stopped the condensation.”

Do you take a deposit?
Not before the measured survey. A deposit is only requested once the survey is complete and you have approved the final schedule and price.
Do you work in hardwood or softwood?
Both. Engineered hardwood is the default where movement or exposure is a concern, and slow-grown softwood is often the better value choice for painted work in sheltered positions. We will tell you which we would specify and why.
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.
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.
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.
