Slim Cavity Units for Darlington properties
If Slim Cavity Units in Darlington were straightforward, there would be a stock size for it. The building stock is colliery terraces, Georgian Durham city stock and Pennine stone housing, so we expect variation before we ever pick up a tape. Set against cold upland winters with heavy rainfall, most joinery here eventually shows frost and saturation damage on unmaintained painted softwood. The detail we will not compromise on is narrow cavities that perform while keeping the sightline historic.
Nothing goes into manufacture until a surveyor has checked each opening on site. Send what you have, even if it is only a phone photo, and we will take it from there.
One local point to factor in: Durham's cathedral setting carries World Heritage-level design scrutiny.
