Barnet's housing runs from Victorian and Edwardian terraces in New Barnet and Chipping Barnet to the broad 1930s semis that line much of the borough — a large share built before cavity walls became standard.
Solid-wall homes in Barnet are among the harder properties to keep warm, because the brick has no cavity to trap heat. External wall insulation tackles that directly, adding an insulating render system to the outside that warms the walls, cuts heat loss and updates the look of the house.
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 cover Chipping Barnet, New Barnet, High Barnet, Whetstone, Totteridge and nearby EN and N postcodes, specialising in older solid-wall and period homes.
Yes — for the better. You choose the render colour and texture, and we detail the windows, sills and eaves so the finish looks deliberate and well-kept, not bolted on.
