What we look for in Gravesend
As well as Gravesend itself, we quote in Grays, Strood and Stanford-le-Hope. It's roughly 14 miles from Gravesend to Maidstone, the largest town in Kent. Homes across the South East range from inter-war semis and post-war estates, which are mostly cavity-walled, to older solid-walled cottages and Victorian town terraces.
Much of Kent 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.
Where one half of a pair in Gravesend is insulated and the other isn't, we detail the boundary so the neighbour can join later.

England: planning and regulations
Before quoting in Gravesend, 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.
Insulating or re-rendering more than half of a wall's area brings in Part L of the Building Regulations, so building control is notified and the wall is upgraded to about 0.30 W/m²K where practical.
Does EWI fix mortgage problems with PRC houses?
Not on its own. Some precast reinforced concrete (PRC) house types were designated defective, and many lenders want a certified structural repair before they will lend. Insulation and render over the outside is not that repair. Other types, such as Wimpey no-fines, are generally treated differently. If mortgageability matters, speak to your lender or a surveyor before booking any work.

Non-traditional houses in Gravesend: questions
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 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.
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 Gravesend?
Yes — we survey and quote non-traditional house insulation in Gravesend (DA12) and nearby Grays, Strood and Stanford-le-Hope, with a fixed written price before any work starts.
