Slim Cavity Units for Colchester properties
Slim Cavity Units is one of those jobs in Colchester where the survey decides everything. Given the estuary bungalows, 1930s ribbon development and timber-framed village stock that dominates locally, standard sizes are the exception not the rule. The weather does the rest: the driest climate in the UK with sharp summer heat here, and shrinkage cracking and glazing bead failure from repeated drying cycles as the predictable result. In practice that means narrow cavities that perform while keeping the sightline historic.
Nothing is ordered until someone has stood in front of the opening with a tape. Tell us what you are working with and we will put a fixed figure in writing.
A detail specific to this area: low rainfall shifts the risk from rot toward movement and seal failure.
