What we look for in Hertford
As well as Hertford itself, we quote in Hoddesdon, Welwyn Garden City and Hatfield. Hertford is about 17 miles from Watford. 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.
Low-level impact damage near drives and bins is a typical EWI repair, and we fix it in Hertford with compatible materials.

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.
How is damaged EWI repaired?
The damaged area is cut back to sound render and board. Wet or crushed insulation is replaced, a new base coat with overlapping mesh is applied, then primer and a matching finish. The repair overlaps the existing mesh so it's reinforced like the original.

EWI repairs in Hertford: 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.
My EWI was installed under a grant — who repairs it?
First check the guarantee paperwork and contact the original installer or guarantee provider. If that route isn't available, we can quote.
