Slim Cavity Units for Sheffield properties

What makes Slim Cavity Units work in Sheffield is usually invisible once it is finished. Local stock is dominated by steel-era terraces, interwar council stock and stone village housing, which sets the sizes and profiles we work to. What accelerates it is cold inland winters with prolonged damp, and condensation-driven decay on single-glazed units in unheated rooms follows sooner than owners expect. Our focus on this is narrow cavities that perform while keeping the sightline historic.

Nothing goes into manufacture until a surveyor has checked each opening on site. One call is usually enough for us to tell you roughly where the price will land.

Bear in mind for this area: large volumes of pre-1919 stock make sash repair the dominant enquiry.
