Slim Cavity Units for High Wycombe properties
The hard part of Slim Cavity Units in High Wycombe is not the making, it is the measuring. Given the Chiltern brick-and-flint cottages alongside large modern estates that dominates locally, standard sizes are the exception not the rule. With chalk-valley damp with cold air pooling overnight in the mix, persistent condensation staining and cill rot on older single-glazed units is a question of when rather than whether. Where we put the effort 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. Send what you have, even if it is only a phone photo, and we will take it from there.
Local factor worth flagging early: AONB designation across much of the county tightens external alteration consent.
