What we look for in Hertfordshire
The East of England has a mix of post-war estates, inter-war semis and older solid brick and flint cottages, with some system-built council homes on post-war estates.
Much of Hertfordshire sits in the lower wind-driven rain exposure bands, which keeps the choice of finishes wide — though hilltop, coastal and exposed gable walls can still need a tougher specification, so we check the actual site.

Approvals in England
Repairs, cleaning and like-for-like patching don't usually need planning permission or building control. If repairs grow into re-rendering more than half of a wall, Building Regulations energy rules can apply.
Listed buildings are the exception: even small external repairs can need listed building consent, so tell us if your property is listed.
What causes EWI to fail?
Most problems start at details: cills that are too short or not sealed, unsealed pipe penetrations, missing drip beads, ground levels too close to the base track, or impact at low level. Where a defect is widespread, we report the likely cause before quoting.

EWI repairs in Hertfordshire: questions
Can damaged EWI be patched?
Yes, provided the board behind is dry and sound. Wet or crushed board is cut out and replaced.
Why is my EWI cracking?
Common causes are missing movement joints, poor mesh overlap, fixing problems or movement in the wall. We look for the cause rather than filling the crack.
Will the repair be visible?
Usually slightly, because the existing finish has weathered. A recoat of the elevation evens it out.
Do you cover all of Hertfordshire?
Yes. We survey and quote EWI repairs across Hertfordshire, including Watford, Stevenage, Hemel Hempstead, St Albans, Welwyn Garden City.
Do I need planning permission in England?
For houses, external wall insulation and render are often permitted development where the finish looks similar to the existing walls. We check your address before quoting.
