Homes and walls in Folkestone
Surveys in Folkestone also cover the surrounding CT19 district and towns such as Dover and Ashford (Kent). It's roughly 31 miles from Folkestone 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 a property in Folkestone is in a conservation area or the front elevation must stay unchanged, internal insulation is often the practical route.

Planning and building control in England
Planning isn't usually involved with internal insulation. Building control is, once more than half of a wall is treated, and listed buildings need listed building consent.
What are the risks with internal insulation?
Insulating inside makes the masonry colder, so moisture risk rises. Weak points are where floor joists bear into the wall, window reveals and corners. A condensation risk check for the build-up, a continuous vapour control layer where specified, and returning insulation into reveals deal with most of it.

Internal wall insulation in Folkestone: questions
Is internal insulation cheaper than external?
Per m² usually yes, but the cost of moving fittings and redecorating narrows the gap on whole-house jobs.
What happens to my radiators and sockets?
They're taken off and refitted on the new wall face. Electrical work is done by a qualified electrician.
Can I stay in the house?
Yes, but each room is out of use while it's worked on, typically 3–5 days.
Do you cover Folkestone?
Yes — we survey and quote internal wall insulation in Folkestone (CT19) and nearby Dover, Ashford (Kent) and Deal, with a fixed written price before any work starts.
