Cavity insulation for new builds and extensions for Stamford Hill properties
Stamford Hill is among the towns we cover in Greater London, alongside Highbury, Tottenham and Holloway. It is around 5 miles north-east of London.
If a wall in Stamford Hill is not suitable, for example because of an undiagnosed damp patch or a very exposed gable, you are told so in writing with the reason. Most Stamford Hill houses built from the 1920s onwards have cavity walls, but the survey still checks each one: cavity width, debris, the condition of the brickwork and how exposed each wall is.
Wind-driven rain is the first thing the surveyor weighs up. Much of Greater London sits in the more sheltered driving-rain zones of the UK, which widens the choice of fill. Exposed elevations, coastal sites and high ground still get checked wall by wall.
On the rules side, in Stamford Hill filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

What we work from
Your architect's or designer's specification and the energy calculation for the job. We match the product, thickness and fixing to that spec, keep cavities clean as the walls rise, and fit cavity trays, closers and stop ends where shown so the building control inspection goes smoothly.
