If your Manchester property was built before about 1930, it almost certainly has solid walls — no cavity to fill. EWI is the only way to properly insulate it without losing internal space.
Why EWI in Manchester?
Significantly improves EPC rating, which matters increasingly for Manchester rental and resale value.
Local context: Manchester, Greater Manchester
A mix of Victorian red-brick terraces, 1930s semis in the south, and a growing stock of high-spec new-builds across the M20 and M21 corridors. Persistent west-coast rainfall and high humidity make breathable silicone finishes a strong fit over older solid-wall stock. We cover the full Greater Manchester area from M1 outwards, including Didsbury, Chorlton, Withington, Fallowfield, Levenshulme and the wider postcodes (M1, M14, M19, M20, M21, M23). Most Manchester jobs are surveyed within 48 hours — we know the streets, parking constraints around landmarks like Manchester Town Hall, 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
- 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.
- 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 Manchester, 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.
Our process in Manchester
- 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 Manchester?
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 Manchester 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 Manchester?
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 Manchester: 2–3 weeks on site including scaffold. Larger detached: 3–5 weeks.
Do you cover Didsbury, Chorlton, Withington, Fallowfield?
Yes — we install EWI across Manchester 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.
