Slim Cavity Units for Corby properties

Slim Cavity Units is one of those jobs in Corby where the survey decides everything. The building stock is ironstone cottages, boot-and-shoe terraces and new town expansion housing, so we expect variation before we ever pick up a tape. The exposure here is dry inland conditions with limited coastal influence, which is exactly the condition that causes seasonal shrinkage and glazing bead loosening on older painted units. Everything we do here comes back to narrow cavities that perform while keeping the sightline historic.

We check on site before committing anything to the saw, and we query what does not add up. Send what you have, even if it is only a phone photo, and we will take it from there.

Worth knowing locally: ironstone reveals absorb water and hold it against frames in wet spells.
