Insulation installers in Walthamstow
Walthamstow's Warner estates and Victorian terraces are much loved and much renovated — and almost all solid-walled. Internal wall insulation suits the conservation streets where the brick frontage should not change, and it can be phased room by room around family life, which is how most E17 owners approach it.
What we install
Four measures, matched to Walthamstow's homes
External wall insulation
Insulated boards and a fresh render finish around the whole house — the strongest upgrade for solid-wall homes where the exterior can change.
Internal wall insulation
Warm boards fitted room by room on the inside of external walls — the answer for terraces, flats and streets where the brick front should stay.
Loft insulation
Top-ups to current standards with the roof ventilation kept clear — usually the cheapest measure with the fastest payback.
Floor insulation
Insulation between the joists of suspended timber floors — ends the draught rising through ground-floor boards.
