Slim Cavity Units for Chesterfield properties
What makes Slim Cavity Units work in Chesterfield is usually invisible once it is finished. The building stock is Peak District gritstone cottages, mill housing and Georgian spa stock, so we expect variation before we ever pick up a tape. The other factor is upland cold with heavy snow loading and hard frost, which is why frost heave damage and swelling on unbalanced-finish joinery is the most common reason people call us. The part that matters is narrow cavities that perform while keeping the sightline historic.
Manufacture only starts once the survey figures are agreed with you in writing. A quick call or a photograph of the opening is usually enough to get you a price.
One thing that catches people out here: Peak Park properties face some of the tightest external alteration controls in England.
