Slim Cavity Units for Haverhill properties
Slim Cavity Units is one of those jobs in Haverhill where the survey decides everything. Given the colour-washed timber-framed cottages, wool-town merchant houses and coastal stock that dominates locally, standard sizes are the exception not the rule. With dry easterly climate with strong coastal salt exposure in the mix, lime-render and timber junction failure where movement opens the seal is a question of when rather than whether. Where we put the effort is narrow cavities that perform while keeping the sightline historic.
A surveyor visits first and records the real dimensions, at several points on each opening. We will price it properly in writing, and we will tell you if it is not worth doing.
Local factor worth flagging early: Lavenham-style timber framing needs specialist scribed repair, not replacement.
