What we look for in Coulsdon
Surveys in Coulsdon also cover the surrounding CR5 district and towns such as Purley and Banstead. 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.
Silicone suits most rendering jobs in Coulsdon, either on its own or over insulation.

Planning and building control in England
Before quoting in Coulsdon, 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.
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.
Silicone or monocouche?
Monocouche is a thicker single-coat cement render used mainly on new blockwork. Silicone is thinner, more flexible and usually more resistant to staining, and it's the finish used over insulation. On older or mixed walls, silicone over a mesh-reinforced base coat is generally the safer choice.

Silicone render in Coulsdon: questions
How long does silicone render take to dry?
It's touch-dry within hours but needs dry weather above about 5°C for the first day or two to cure properly.
Can I paint silicone render later?
Yes, with a compatible silicone paint, though through-coloured render rarely needs it.
Does silicone render crack?
The mesh-reinforced base coat and the render's flexibility make cracking much less likely than with sand and cement, but structural movement in the wall can still show through.
