We design and install full EWI systems across Wigan — insulation board, adhesive, mechanical fixings, base coat with mesh, then a through-coloured silicone topcoat.
Why EWI in Wigan?
Because the insulation sits outside the structure, the wall stays warm — eliminating cold-bridging and internal condensation.
Local context: Wigan, Greater Manchester
Former mining stock and large postwar semi-detached estates; significant pebbledash and rough-cast render in need of refresh. West-Lancashire rainfall and damp clay soils put a premium on properly prepared substrates. We cover the full Greater Manchester area from WN1 outwards, including Standish, Aspull, Orrell, Pemberton, Shevington and the wider postcodes (WN1, WN2, WN3, WN5, WN6). Most Wigan jobs are surveyed within 48 hours — we know the streets, parking constraints around landmarks like Wigan Pier, and the typical substrates we'll find on the wall.
Benefits
- Major reduction in heating bills.
- Eliminates cold bridging and most internal condensation.
- Brand-new render façade included.
- Significant EPC uplift.
- Improves acoustic performance.
- No loss of internal floor space.
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 Wigan, 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.
Our process in Wigan
- Free survey, written quote with U-value information.
- Confirm board type, finish, colour.
- Scaffold; protect everything not being treated.
- Bond and fix insulation boards.
- Apply base coat + mesh; detail reveals, sills, drip beads.
- Topcoat in chosen finish.
- Walk-round, sign-off, scaffold down.

Frequently asked questions
How much can EWI save on bills in Wigan?
Typically 25–35% off heating demand for solid-wall properties. The exact figure depends on current insulation, heating system, and how the house is used.
What thickness of insulation do you use?
Most Wigan projects sit between 90mm and 150mm, depending on the U-value target and existing detailing. We size it on survey.
Does EWI need planning permission in Wigan?
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 Wigan: 2–3 weeks on site including scaffold. Larger detached: 3–5 weeks.
Do you cover Standish, Aspull, Orrell, Pemberton?
Yes — we install EWI across Wigan and the surrounding areas.

EWI is a serious project — done well it transforms the house; done badly it traps damp. We do it properly. Get in touch.
