Timber glazing upgrades in Marlborough
If you are looking at Retrofit Double Glazing in Marlborough, the timber is only half the decision. Property here runs to chalk-downland cob and thatch, Bath stone terraces and garrison housing, and each of those brings its own set of dimensions. With exposed downland wind with driving rain in the mix, wind-driven water forced past worn weatherseals is a question of when rather than whether. The part that matters is reworking the rebate so a sealed unit fits without bulking the section.
Nothing goes into manufacture until a surveyor has checked each opening on site. Tell us the problem rather than the solution and we will advise on both.
Something particular to this area: 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.”

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.
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.
