Timber glazing upgrades in Preston
The Retrofit Double Glazing we make for Preston is set out from a survey, not a size chart. Local stock is dominated by cotton-town terraces, Pennine stone cottages and Fylde coast resort stock, which sets the sizes and profiles we work to. Then there is high rainfall inland and severe wind exposure on the Fylde coast, which reliably produces wind-driven rain penetration at meeting rails and sill joints given enough seasons. The value is in reworking the rebate so a sealed unit fits without bulking the section, not in the timber bill.
Nothing goes into manufacture until a surveyor has checked each opening on site. One call is usually enough for us to tell you roughly where the price will land.
Something particular to this area: coastal Fylde stock needs the same specification discipline as the South West.

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

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

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.
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.
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.
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.
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.
