We design and install full EWI systems across Sunderland — insulation board, adhesive, mechanical fixings, base coat with mesh, then a through-coloured silicone topcoat.
Why EWI in Sunderland?
Because the insulation sits outside the structure, the wall stays warm — eliminating cold-bridging and internal condensation.
Local context: Sunderland, Tyne and Wear
Large interwar and postwar estates with original cement render and pebbledash; coastal-facing properties take the brunt of North Sea weather. Salt spray and easterly gales degrade non-flexible renders quickly — modern silicone systems extend coastal lifespan dramatically. We cover the full Tyne and Wear area from SR1 outwards, including Roker, Seaburn, Fulwell, Ashbrooke, Tunstall and the wider postcodes (SR1, SR2, SR3, SR4, SR5, SR6). Most Sunderland jobs are surveyed within 48 hours — we know the streets, parking constraints around landmarks like Stadium of Light, and the typical substrates we'll find on the wall.
Benefits
- 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.
- Significant EPC uplift.
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 Sunderland, 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 Sunderland
- Survey, design, and itemised quote.
- Scaffold + project plan.
- Strip rainwater goods; prep substrate.
- Fix boards (typically 90–150mm depending on target U-value).
- Detail all reveals, drip beads, expansion joints.
- Base coat + mesh.
- Through-coloured topcoat + handover.

Frequently asked questions
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 Sunderland property, we'll point you to it.
How much can EWI save on bills in Sunderland?
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 Sunderland 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 Sunderland?
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.
