Slim Cavity Units for Haltwhistle properties

Slim Cavity Units is one of those jobs in Haltwhistle where the survey decides everything. Local property is overwhelmingly border stone farmhouses, colliery terraces and coastal fishing cottages, which is why we never quote from a catalogue. What accelerates it is the harshest combination of cold, wind and salt in England, and combined frost and salt damage stripping finishes within a few seasons follows sooner than owners expect. What you are paying for is narrow cavities that perform while keeping the sightline historic.

Nothing goes into manufacture until a surveyor has checked each opening on site. One call is usually enough for us to tell you roughly where the price will land.

One thing that catches people out here: Northumberland exposure justifies the heaviest sections and stainless fixings.
