Slim Cavity Units for Derby properties
Half the Slim Cavity Units problems we fix in Derby started as a sizing assumption. Given the Peak District gritstone cottages, mill housing and Georgian spa stock that dominates locally, standard sizes are the exception not the rule. 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. Our focus on this is narrow cavities that perform while keeping the sightline historic.
Every job is measured on site first, because drawn sizes and built sizes are seldom the same. One call is usually enough for us to tell you roughly where the price will land.
Bear in mind for this area: Peak Park properties face some of the tightest external alteration controls in England.
