Slim Cavity Units for Belper properties
What makes Slim Cavity Units work in Belper is usually invisible once it is finished. You are mostly dealing with Peak District gritstone cottages, mill housing and Georgian spa stock around here, so openings vary more than people expect. Because of upland cold with heavy snow loading and hard frost, we see frost heave damage and swelling on unbalanced-finish joinery more often here than in most of the country. What you are paying for is narrow cavities that perform while keeping the sightline historic.
Nothing is ordered until someone has stood in front of the opening with a tape. Get in touch and we will be straight with you about cost and timescale.
One local point to factor in: Peak Park properties face some of the tightest external alteration controls in England.
