Timber glazing upgrades in Leatherhead
If Slim Cavity Units in Leatherhead were straightforward, there would be a stock size for it. The housing here is largely interwar detached stock, Arts and Crafts houses and 1930s semis, and that shapes what will actually fit. Locally you are contending with mild but damp, with heavy tree cover holding moisture against elevations, so sap staining and green growth on north elevations followed by joint opening is the fault we are called out to. Where we put the effort is narrow cavities that perform while keeping the sightline historic.
A surveyor visits first and records the real dimensions, at several points on each opening. Get in touch and we will be straight with you about cost and timescale.
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.”

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.
Do you fit, or supply only?
Both. Supply-only is common for trade and contractor clients. For private clients we usually recommend supply and fit, because responsibility for the fit and the finish then sits in one place.
