We design and install full EWI systems across Chorley — insulation board, adhesive, mechanical fixings, base coat with mesh, then a through-coloured silicone topcoat.
Why EWI in Chorley?
Because the insulation sits outside the structure, the wall stays warm — eliminating cold-bridging and internal condensation.
Local context: Chorley, Lancashire
Strong belt of 1980s–2000s new-build estates plus older brick terraces; thin-coat silicone is widely specified on the newer stock. West-Lancashire wet climate makes water-repellence the headline requirement. We cover the full Lancashire area from PR6 outwards, including Adlington, Eccleston, Euxton, Coppull, Whittle-le-Woods and the wider postcodes (PR6, PR7). Most Chorley jobs are surveyed within 48 hours — we know the streets, parking constraints around landmarks like Astley Hall, and the typical substrates we'll find on the wall.
Benefits
- Brand-new render façade included.
- Significant EPC uplift.
- Improves acoustic performance.
- No loss of internal floor space.
- Refurbishes tired solid-wall properties to modern standards.
- Long-life system when detailed properly.
Local considerations
- EWI changes the external footprint of the building by 100–200mm — windows, sills, rainwater goods and roof overhang all need designing in.
- Get the breathability right — for older solid-wall properties in Chorley, mineral wool with a silicone topcoat is usually safer than EPS.
- Reveals, sills and drip beads are where EWI fails. We detail these properly; many cheap installers don't.
- Plan for moved rainwater goods, soil stacks and meter boxes — the project is more than just 'boards and render'.
- EWI on a damp wall just traps the damp. Cure the damp problem first.

Frequently asked questions
Does EWI need planning permission in Chorley?
Usually no for like-for-like exteriors on standard housing, but conservation areas and listed properties need checking. We'll advise on survey.
Can EWI fix damp?
EWI eliminates cold-bridging condensation — the most common cause of 'damp' patches on solid walls. It doesn't fix rising or penetrating damp, which need addressing separately.
What's the typical job duration?
Most semis in Chorley: 2–3 weeks on site including scaffold. Larger detached: 3–5 weeks.
Do you cover Adlington, Eccleston, Euxton, Coppull?
Yes — we install EWI across Chorley and the surrounding areas.
Will EWI affect my windows?
Window reveals will need re-detailing. We design new reveal beads and trims into the quote — it's not a hidden extra.
Are there grants available?
Grant schemes change. Ask on enquiry — if there's an active scheme that fits your Chorley property, we'll point you to it.
Send us a few photos on WhatsApp and we'll come back with an indicative price the same day.
