What we do and how we do it
The hard part of Thermal Survey in the UK is not the making, it is the measuring. Most of what we survey locally is a mix of period and modern stock, which is not built to any modern module. Because of the full range of UK exposure conditions, we see coating failure followed by rot at the joints more often here than in most of the country. Everything we do here comes back to measuring where heat is going before anyone recommends a spend.
Every job is measured on site first, because drawn sizes and built sizes are seldom the same. One call is usually enough for us to tell you roughly where the price will land.
Something particular to this area: specification should always be matched to local exposure.
Specification
- Engineered hardwood or slow-grown softwood, FSC certified
- Factory-applied microporous finish in any RAL or heritage colour
- Sealed units, slim-cavity units or single glazing with putty line
- Manufactured to survey dimensions, not to a stock size chart
- Delivered UK-wide with chain-of-custody paperwork
Keep the joinery you have
Upgrade performance without throwing away sound timber windows.
Cheaper than replacement
Typically a fraction of the cost of new units, with much of the benefit.
Measured before recommended
We find where the heat is actually going before suggesting a spend.
Ventilation kept compliant
Sealing a house up without creating a condensation problem.
What clients tell us
Feedback collected directly from completed projects. Full written references are available on request before you commit.
“The survey showed most of the loss was around the frames, not through the glass at all.”
Verified client, UK-wide“Half the cost of replacement and the rooms hold heat noticeably better.”
Verified client, UK-wide“They fitted trickle vents we had not thought about, which stopped the condensation.”

Frequently asked questions
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 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.
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.
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.
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.
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.
Can you price from drawings?
Yes. Send a drawing set or a schedule and we will price against it. If anything is ambiguous we will query it before quoting rather than assume and reprice later.
