Timber glazing upgrades in Blackburn
We take a fair volume of Secondary Glazing work across Blackburn, and almost none of it repeats. Most of what we survey locally is cotton-town terraces, Pennine stone cottages and Fylde coast resort stock, which is not built to any modern module. 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 detail we will not compromise on is internal glazing that leaves the original window entirely untouched.
Nothing goes into manufacture until a surveyor has checked each opening on site. Photographs and approximate sizes are all we need to start.
A local consideration we always raise: 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“Half the cost of replacement and the rooms hold heat noticeably better.”
Verified client, Lancashire“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.
