Slim Cavity Units across West Sussex
What makes Slim Cavity Units work in West Sussex is usually invisible once it is finished. The housing here is largely Sussex flint cottages, Regency seafront terraces and postwar new town housing, and that shapes what will actually fit. Because of strong coastal exposure with salt spray inland of the shoreline, we see finish erosion on seaward elevations within a few years of coating more often here than in most of the country. What we concentrate on 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. Tell us the problem rather than the solution and we will advise on both.
Local factor worth flagging early: seafront properties need a shorter recoating cycle than inland equivalents.

Frequently asked questions
Do you cover West Sussex?
Yes. We cover the whole of West Sussex including Crawley, Worthing, Horsham, Bognor Regis and the surrounding villages. Seafront properties need a shorter recoating cycle than inland equivalents. Because strong coastal exposure with salt spray inland of the shoreline, we allow for it at survey stage rather than discovering it on the day.
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.
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.
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.
