Local considerations in Heston
We also cover Hounslow and Isleworth, close to Heston. 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.
For Heston homeowners matching a new extension to an existing rendered house, we compare monocouche and silicone samples first.

Approvals in England
Planning in Heston 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.
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.
Why does monocouche sometimes look patchy?
Colour variation (often called shading) can appear if it's applied in poor weather, on walls with uneven suction, or in sections on different days. Working an elevation in one go in suitable conditions keeps the colour even.

Monocouche render in Heston: questions
How long does monocouche last?
Typically 20 years or more on a suitable wall, depending on exposure and detailing.
Monocouche or silicone for an extension?
Both work on new blockwork. Silicone over a base coat costs a little more but tends to stay cleaner.
Is monocouche waterproof?
It's water-resistant and sheds rain, while still allowing some vapour through.
