Slim Cavity Units for Swanage properties

Half the Slim Cavity Units problems we fix in Swanage started as a sizing assumption. You are mostly dealing with Purbeck stone cottages, Victorian resort villas and thatched inland villages around here, so openings vary more than people expect. exposed Channel coast with intense salt and UV load sets the pace of decay, and rapid finish failure and fixings corrosion within a few seasons on seafront stock is how it shows up first. The part that matters is narrow cavities that perform while keeping the sightline historic.

The survey happens before manufacture, which is why our units fit without packing or trimming. Give us the basics and you will have a written figure, not a range that moves later.

A local consideration we always raise: Jurassic Coast properties need stainless fixings as standard, not an upgrade.
