Before we quote in St Albans
We also cover Harpenden and Hatfield, close to St Albans. St Albans is about 7 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.
On tree-shaded or north-facing walls in St Albans, silicone's water repellence helps it stay cleaner for longer.

Permissions in England
For a house in St Albans, 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.
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 St Albans: 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.
Can I paint silicone render later?
Yes, with a compatible silicone paint, though through-coloured render rarely needs it.
