Slim Cavity Units for Alnwick properties

Slim Cavity Units is one of those jobs in Alnwick where the survey decides everything. You will find mostly border stone farmhouses, colliery terraces and coastal fishing cottages in this area, and it moves as it ages. the harshest combination of cold, wind and salt in England sets the pace of decay, and combined frost and salt damage stripping finishes within a few seasons is how it shows up first. The value is in narrow cavities that perform while keeping the sightline historic, not in the timber bill.

We check on site before committing anything to the saw, and we query what does not add up. Rough dimensions and a couple of photographs are enough for us to price it properly.

Local factor worth flagging early: Northumberland exposure justifies the heaviest sections and stainless fixings.
