What we look for in Hitchin
We cover Hitchin and nearby Letchworth Garden City, Stevenage and Luton. Hitchin sits around 21 miles from Watford. The East of England has a mix of post-war estates, inter-war semis and older solid brick and flint cottages, with some system-built council homes on post-war estates.
Much of Hertfordshire 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.
If you're re-rendering in Hitchin, we'll show you what adding insulation under the silicone would cost at the same time.

Planning and building control in England
For a house in Hitchin, 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.
If the work covers more than half of a wall, or a quarter of the building's whole envelope, it counts as renovating a thermal element, with a target of about 0.30 W/m²K where feasible.
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 Hitchin: questions
Can silicone render go over old render?
If the old render is sound and well bonded, often yes after cleaning and priming. Hollow or cracked areas are cut out and repaired first.
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.
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.
