Slim Cavity Units for Witham properties
We take a fair volume of Slim Cavity Units work across Witham, and almost none of it repeats. With estuary bungalows, 1930s ribbon development and timber-framed village stock making up much of the area, off-the-shelf sizes rarely line up. The other factor is the driest climate in the UK with sharp summer heat, which is why shrinkage cracking and glazing bead failure from repeated drying cycles is the most common reason people call us. The part that matters is narrow cavities that perform while keeping the sightline historic.
We survey before anything is cut, so the schedule reflects the opening as built rather than as drawn. Ask us for a figure and you will get one, with the lead time stated alongside it.
Local factor worth flagging early: low rainfall shifts the risk from rot toward movement and seal failure.
