Slim Cavity Units for Hackney properties
Slim Cavity Units across Hackney tends to be driven by the condition of what is already there. Because the area is mainly Victorian and Edwardian terraces, mansion blocks and post-war infill, no two openings measure quite the same. The other factor is high pollution load and sheltered urban humidity, which is why paint failure on south-facing sashes and rot at the bottom rail is the most common reason people call us. Our focus on this 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. Give us the basics and you will have a written figure, not a range that moves later.
One thing that catches people out here: large numbers of properties sit in conservation areas with like-for-like replacement conditions.
