Timber glazing upgrades in St Helens
What makes Secondary Glazing work in St Helens is usually invisible once it is finished. The building stock is Georgian merchant housing, dockland terraces and Victorian resort villas, so we expect variation before we ever pick up a tape. With Irish Sea exposure with salt-laden prevailing wind in the mix, salt-accelerated finish breakdown on west-facing elevations is a question of when rather than whether. What we concentrate on is internal glazing that leaves the original window entirely untouched.
We check on site before committing anything to the saw, and we query what does not add up. One call is usually enough for us to tell you roughly where the price will land.
Something particular to this area: Liverpool's Georgian quarter carries strict conservation-area window controls.

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

Do you deliver nationwide?
Yes, we deliver across England, Wales and Scotland. Delivery is priced into the quotation so there is no separate charge added later.
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.
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.
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.
How long does a typical order take?
Most made-to-size orders run six to ten weeks from survey to delivery. Conservation and heavily detailed work can take longer, and we confirm the lead time in writing at quotation rather than leaving it open.
