What we look for in Dereham
We cover Dereham and nearby Norwich, Thetford and King's Lynn. Dereham sits around 16 miles from Norwich. 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 Norfolk 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.
For concrete houses in Dereham, we report any visible spalling or cracking before quoting the insulation, not after.

Planning and building control in England
Before quoting in Dereham, we check whether the property is in a conservation area, under an Article 4 direction or listed, because that decides whether changing the outside needs planning permission.
Building control applies once more than half of a wall is insulated or re-rendered, or more than a quarter of the whole building envelope, and your written quote says how that's handled.
What does the work involve?
After checking the wall condition, any spalling concrete or corroded steel is reported before boards go on. Fixings are chosen for the substrate — concrete, steel-framed panels or mixed constructions — and the system is detailed around eaves, cills and the junction with neighbouring properties, which may not be insulated.

Non-traditional houses in Dereham: questions
Can you insulate a Wimpey no-fines house?
Yes. No-fines houses have solid poured-concrete walls with no cavity, so EWI is the usual route. The survey checks the concrete condition first.
Will EWI make my house mortgageable?
It can make a house more attractive and better insulated, but it does not replace a certified structural repair where a lender requires one. Ask your lender before relying on it.
Can you put EWI on a BISF house?
Yes, with care. The steel frame and upper-storey cladding need a system and fixing method designed for that construction, and the condition of the frame should be understood first.
Do you cover Dereham?
Yes — we survey and quote non-traditional house insulation in Dereham (NR19) and nearby Norwich, Thetford and King's Lynn, with a fixed written price before any work starts.
