If your Hull 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 Hull?
Significantly improves EPC rating, which matters increasingly for Hull rental and resale value.
Local context: Hull, East Yorkshire
Long runs of Edwardian terraces in the city, plus large 1950s and 60s estates with rendered concrete-frame stock ideal for full-system upgrade. Flat, exposed coastal-estuary location means wind-driven rain on east elevations — silicone with high water repellence is the safe choice. We cover the full East Yorkshire area from HU1 outwards, including Cottingham, Anlaby, Willerby, Hessle, Sutton and the wider postcodes (HU1, HU3, HU5, HU6, HU7, HU8, HU16). Most Hull jobs are surveyed within 48 hours — we know the streets, parking constraints around landmarks like The Deep, and the typical substrates we'll find on the wall.
Benefits
- No loss of internal floor space.
- Refurbishes tired solid-wall properties to modern standards.
- Long-life system when detailed properly.
- Major reduction in heating bills.
- Eliminates cold bridging and most internal condensation.
- Brand-new render façade included.
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 Hull, 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 Hull
- Survey + thermal performance calc.
- Scaffold + access design (especially important on tight {town} streets).
- Substrate prep — make good, reposition rainwater goods.
- Fix EWI boards; cut around openings; detail reveals.
- Mesh-reinforced base coat.
- Through-coloured silicone TC topcoat.
- Final inspection + handover paperwork.

Frequently asked questions
Do you cover Cottingham, Anlaby, Willerby, Hessle?
Yes — we install EWI across Hull 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 Hull property, we'll point you to it.
How much can EWI save on bills in Hull?
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 Hull 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 Hull?
Usually no for like-for-like exteriors on standard housing, but conservation areas and listed properties need checking. We'll advise on survey.

We design EWI from the substrate up — board type, fixings, mesh, beads, finish — to match your specific Hull property. No off-the-shelf specs.
