Timber glazing upgrades in Sunningdale
Nothing about Slim Cavity Units in Sunningdale is settled until someone has been on site. With Thames-side villas, Victorian terraces and dense 1980s commercial fit-out stock making up much of the area, off-the-shelf sizes rarely line up. river humidity and localised flood exposure is the local complication, and swelling and binding on ground-floor doors after flood or high water table events is what it eventually causes. In practice that means narrow cavities that perform while keeping the sightline historic.
A surveyor visits first and records the real dimensions, at several points on each opening. We will price it properly in writing, and we will tell you if it is not worth doing.
Something particular to this area: flood-zone properties benefit from raised thresholds and marine-grade fixings.

“The survey showed most of the loss was around the frames, not through the glass at all.”
Verified client, Berkshire“Half the cost of replacement and the rooms hold heat noticeably better.”
Verified client, Berkshire“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.
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.
Can you match an existing profile?
Yes. If you can supply a section, a photograph with a rule in shot, or an old unit, we can replicate the profile. For conservation work this is usually the condition the planning officer will apply.
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.
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.
