Slim Cavity Units for Spennymoor properties
People come to us about Slim Cavity Units in Spennymoor once the cheap option has already failed. With colliery terraces, Georgian Durham city stock and Pennine stone housing making up much of the area, off-the-shelf sizes rarely line up. Because of cold upland winters with heavy rainfall, we see frost and saturation damage on unmaintained painted softwood more often here than in most of the country. What you are paying for is narrow cavities that perform while keeping the sightline historic.
We would rather spend an hour surveying than a week correcting. Ask us for a figure and you will get one, with the lead time stated alongside it.
Something particular to this area: Durham's cathedral setting carries World Heritage-level design scrutiny.
