Finchley's N3 and N12 streets are full of 1930s semis and Edwardian houses — a housing stock where solid-wall construction is common and cavity insulation often isn't an option.
Where there's no cavity, the heat escapes through the brick itself. External wall insulation is the right answer for these Finchley homes: an insulating layer fixed to the outside and finished in render, keeping rooms warmer for longer and lifting the appearance of an older property.
EWI is a continuous insulating layer fixed to the outside of your home, finished with a weatherproof render. Because it sits outside, your rooms keep their floor space, and the masonry stays warmer.
We don't quote specific savings figures — your surveyor explains what results are realistic for your property.
A real surveyor visits, measures up and checks wall build-up, damp risks, access and planning context. You receive an itemised written quote covering the system, render type, detailing and scaffolding. We install boards, reinforcing mesh and render with a daily clean-down, then finish with inspection, sign-off and warranty paperwork.
We serve Church End, North Finchley, East Finchley and the surrounding N2, N3 and N12 postcodes, specialising in older solid-wall homes.
Usually, yes. Internal insulation eats into room space and is disruptive inside; external insulation keeps your floor area and treats the whole wall — but the survey confirms what suits your property.
