Timber glazing upgrades in Sudbury
Most Thermal Survey enquiries we take in Sudbury start with an opening that is not a standard size. Property here runs to colour-washed timber-framed cottages, wool-town merchant houses and coastal stock, and each of those brings its own set of dimensions. Locally you are contending with dry easterly climate with strong coastal salt exposure, so lime-render and timber junction failure where movement opens the seal is the fault we are called out to. The value is in measuring where heat is going before anyone recommends a spend, not in the timber bill.
Every job is measured on site first, because drawn sizes and built sizes are seldom the same. One call is usually enough for us to tell you roughly where the price will land.
A detail specific to this area: Lavenham-style timber framing needs specialist scribed repair, not replacement.

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

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.
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.
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.
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.
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.
