External Insulation & Rendering in Hanwell
External wall insulation and through-coloured render on solid-wall properties — warmer house, lower bills, and a facade that is not cracking in two winters.
Solid-walled West London stock loses a great deal of heat through the walls, and external insulation is usually the single most effective fix. The work lives and dies on the details: beads at every opening, correct depth at the base, reveals and sills extended so water throws clear, and the roof verge adjusted for the new wall thickness. Skip those and you get cracking and damp, which is why cheap render jobs fail.
External Insulation & Rendering in Hanwell: what to know locally
Victorian and Edwardian terraces and semis, with 1930s housing towards Boston Manor and larger properties near Churchfields.
Hanwell sits on relatively generous plots for the price point, which makes it good ground for rear extensions and loft conversions on properties where the budget would not stretch in Ealing or Chiswick. Older stock often has solid walls and benefits from external insulation.
Planning authority: Ealing Council. Parts of Hanwell including the Golden Manor and Churchfields areas carry conservation designation. The Victorian stock frequently has solid walls, making external wall insulation worth considering alongside other work.

External Insulation & Rendering in Hanwell — questions
Do you cover Hanwell?
Yes — Hanwell and the W7 postcodes are part of our core working area, along with Ealing, Greenford, Acton. Being local means a site visit within days rather than weeks.
Which council handles planning for Hanwell?
Ealing Council. Parts of Hanwell including the Golden Manor and Churchfields areas carry conservation designation. The Victorian stock frequently has solid walls, making external wall insulation worth considering alongside other work.
Will external insulation stop condensation and damp?
It usually helps a great deal, because it lifts the internal wall surface temperature above the dew point, which is where surface condensation and mould start. It does not fix penetrating or rising damp — those need dealing with first.
Do I need planning permission for external render?
On most houses, cladding or rendering is permitted development, but not in conservation areas, on listed buildings, or where an Article 4 direction applies. We check the property before quoting.
How much will it cut my heating bills?
On an uninsulated solid-wall house it is a substantial reduction, but the honest answer is that it depends on your existing heating, glazing and how you use the house. We will not quote you a percentage we cannot stand behind.
