Timber glazing upgrades in Truro
The Retrofit Double Glazing we make for Truro is set out from a survey, not a size chart. With granite fishermen's cottages, slate-hung terraces and modern coastal builds making up much of the area, off-the-shelf sizes rarely line up. What accelerates it is the most severe salt and wind exposure in England, and accelerated coating failure and salt crystallisation damage at glazing lines follows sooner than owners expect. The value is in reworking the rebate so a sealed unit fits without bulking the section, not in the timber bill.
Each opening is recorded individually, since a terrace of identical houses rarely is. We will price it properly in writing, and we will tell you if it is not worth doing.
A local consideration we always raise: Cornish exposure grades mean specification should assume worst-case wind-driven rain.

“The survey showed most of the loss was around the frames, not through the glass at all.”
Verified client, Cornwall“Half the cost of replacement and the rooms hold heat noticeably better.”
Verified client, Cornwall“They fitted trickle vents we had not thought about, which stopped the condensation.”

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 do you handle glazing?
Standard double glazed units for most work, and slim-cavity units where a conservation officer has restricted sightlines. Single glazing with putty lines is available where the consent requires it.
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.
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.
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.
