Timber glazing upgrades in St Ives
Thermal Survey in St Ives rewards patience at the setting-out stage. Local stock is dominated by granite fishermen's cottages, slate-hung terraces and modern coastal builds, which sets the sizes and profiles we work to. the most severe salt and wind exposure in England is the local complication, and accelerated coating failure and salt crystallisation damage at glazing lines is what it eventually causes. What we concentrate on is measuring where heat is going before anyone recommends a spend.
We survey before anything is cut, so the schedule reflects the opening as built rather than as drawn. Ask us for a figure and you will get one, with the lead time stated alongside it.
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.”

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 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.
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.
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.
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.
