Slim Cavity Units for Leiston properties
Slim Cavity Units is one of those jobs in Leiston where the survey decides everything. The building stock is colour-washed timber-framed cottages, wool-town merchant houses and coastal stock, so we expect variation before we ever pick up a tape. The weather does the rest: dry easterly climate with strong coastal salt exposure here, and lime-render and timber junction failure where movement opens the seal as the predictable result. Everything we do here comes back to 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.
A local consideration we always raise: Lavenham-style timber framing needs specialist scribed repair, not replacement.
