Insulation installers in Dartford
Dartford mixes Victorian terraces near the town centre with large post-war estates and plenty of recent new-build. The older terraces are solid-walled; the mid-century homes usually have cavities and lofts that were insulated to standards far below today's — topping up is cheap and quick.
What we install
Four measures, matched to Dartford'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.
