Timber glazing upgrades in Farnham
What makes Thermal Survey work in Farnham is usually invisible once it is finished. Because the area is mainly interwar detached stock, Arts and Crafts houses and 1930s semis, no two openings measure quite the same. The other factor is mild but damp, with heavy tree cover holding moisture against elevations, which is why sap staining and green growth on north elevations followed by joint opening is the most common reason people call us. What you are paying for is measuring where heat is going before anyone recommends a spend.
Nothing is ordered until someone has stood in front of the opening with a tape. Rough dimensions and a couple of photographs are enough for us to price it properly.
Local factor worth flagging early: high-value stock where owners specify hardwood over softwood as standard.

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

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 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 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.
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.
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.
