Cavity wall suitability survey for Tonbridge properties

Tonbridge sits in Kent, around 12 miles south-west of Maidstone. We work across the TN9 district, including nearby Tunbridge Wells, Sevenoaks and Maidstone.

Every inspection point in Tonbridge is photographed and logged, so you have a record to show a buyer, lender or contractor. The written result for your Tonbridge property is plain English: what we found, what it means and what, if anything, to do next.

Every elevation is judged on its own exposure. Much of Kent 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.

For regulations, in Tonbridge filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

Rules in England

Filling a cavity is notifiable building work and needs a building notice or competent-person self-certification if insulation work follows.

What the surveyor checks

Wall construction and thickness at window reveals; cavity width and debris with a borescope; brickwork, pointing, render, sills, gutters and downpipes; signs of damp inside and out; air bricks and flues; joins with neighbours and extensions; and the exposure of each elevation to wind-driven rain.

Cavity wall suitability survey in Tonbridge: questions

Is my Tonbridge home too exposed for cavity insulation?

Much of Kent is in the more sheltered driving-rain zones, but exposed and coastal sites are still checked carefully. The survey records the exposure of each wall before recommending a material, or recommending against filling.

Will you tell me if I do not need any work?

Yes. If the findings show nothing needs doing, or a cheaper fix such as clearing a gutter will do, we say so.

Do you cover Tonbridge?

Yes. Tonbridge and the TN9 postcode district are within our Kent coverage, along with nearby Tunbridge Wells and Sevenoaks.

Is there VAT on a cavity wall survey in Tonbridge?

The survey is free when it is for an install quote. A standalone survey report is not insulation, so it is normally standard-rated for VAT, and the price you are quoted includes it.
