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

Approvals in England
For a house in Isleworth, external insulation or render is often permitted development if it looks similar to the existing walls; conservation areas, flats, commercial buildings and listed buildings need permission or consent, so we check your address first.
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.
Where is monocouche used?
Monocouche is best on new or sound blockwork and brickwork with consistent suction — extensions, new builds and garden walls. It's applied thicker than thin-coat renders and scraped once firm to reveal the texture.

Monocouche render in Isleworth: questions
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.
How long does monocouche last?
Typically 20 years or more on a suitable wall, depending on exposure and detailing.
Is monocouche waterproof?
It's water-resistant and sheds rain, while still allowing some vapour through.
