Mitcham: walls, weather and approvals
Surveys in Mitcham also cover the surrounding CR4 district and towns such as Morden and Wimbledon. London's housing includes a large stock of Victorian and Edwardian solid-wall terraces, inter-war semis and post-war blocks, and conservation areas cover many streets — so planning is often the first question for external work.
Much of Greater London 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.
EPS is a common choice for two-storey houses, mainly on cost and weight, and we price it alongside mineral wool for homes in Mitcham.

Approvals in England
Before quoting in Mitcham, 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.
When is EPS the right choice?
EPS suits most two-storey houses, bungalows and park homes where the wall is sound and there are no fire-height restrictions. It is a good fit where eaves are shallow, because grey EPS can hit the target with less thickness. On buildings with a storey 11 metres or more above ground, or where the guidance asks for non-combustible materials, mineral wool is used instead.

EPS insulation in Mitcham: questions
Is EPS insulation safe on a house?
EPS is used inside render systems that are fire-tested as a whole. On low-rise houses it is widely used. On taller buildings, or where guidance calls for non-combustible materials, mineral wool systems are specified instead.
Will woodpeckers damage EPS?
It happens occasionally, especially near woodland. Damage is to the render and board surface and is repaired with a mesh patch and colour-matched finish.
White or grey EPS?
Grey graphite EPS insulates better per millimetre, so it is the pick where space is tight at the eaves or around windows. White EPS is slightly cheaper and works well where the extra thickness isn't a problem.
Do you cover Mitcham?
