Before we quote in Staines
We cover Staines and nearby Egham, Ashford (Surrey) and Feltham. Staines is about 8 miles from Woking. 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 Surrey 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 blocks in Staines, we start with height, storeys and the planning position, because those decide the system.

Permissions in England
Before quoting in Staines, 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.
On residential buildings with a storey 11 metres or more above ground, guidance points to non-combustible external wall materials, and combustible materials are banned in relevant buildings 18 metres and over, so we specify mineral wool systems there.
How disruptive is it for residents?
Most work happens from scaffolding outside. Residents may need to allow brief access to extend window cills, vents or flues from the inside. We provide a notice for residents covering dates, scaffold, and how to raise concerns.

Flats and blocks in Staines: questions
Do you work on high-rise buildings?
Tell us the height and number of storeys. Buildings in the higher-risk category have a separate regulatory route, and we'll say plainly if we're not the right contractor.
Can one flat have external wall insulation on its own?
Rarely. The outside walls are usually owned by the freeholder, the result would look patchy, and planning is unlikely. Whole-building schemes are the norm.
Who pays for EWI on a leasehold block?
In England and Wales, usually the leaseholders through the service charge, depending on the lease, and the landlord must follow the Section 20 consultation process for major works.
Do you cover Staines?
Yes — we survey and quote EWI for flats and blocks in Staines (TW18) and nearby Egham, Ashford (Surrey) and Feltham, with a fixed written price before any work starts.
