Part of every quote

Homes and walls in Dartford
We also cover Bexley and Swanley, close to Dartford. It's roughly 18 miles from Dartford 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 Dartford is insulated and the other isn't, we detail the boundary so the neighbour can join later.

England: planning and regulations
Planning in Dartford follows England's national rules: similar-looking finishes on houses are usually permitted, while flats, commercial premises, conservation areas and streets under an Article 4 direction need an application.
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 Dartford: 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 Dartford?
Yes — we survey and quote non-traditional house insulation in Dartford (DA1) and nearby Bexley, Swanley and Welling, with a fixed written price before any work starts.
