Cavity wall suitability survey for Sandown properties

Our Isle of Wight coverage takes in Sandown (PO36) and nearby Ryde and Cowes. It is around 6 miles south of Ryde.

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

Every elevation is judged on its own exposure. The Isle of Wight has a mix of moderate and more exposed sites. Hilltop, coastal and west-facing walls take the brunt of wind-driven rain, so the survey records exposure for each elevation before a material is chosen.

As for paperwork, in Sandown 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.

Cavity wall suitability survey in Sandown: questions

Which building regulations route applies in Sandown?

Sandown is in England, so filling a cavity is notifiable building work and needs a building notice or competent-person self-certification. We confirm the route in writing on your quote.

Do you work on rented homes in Sandown?

Yes. Landlords and agents in Sandown can book batch visits, and work is arranged around tenants.

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.

Is my Sandown home too exposed for cavity insulation?

The Isle of Wight has a mix of moderate and more exposed sites, so each wall is judged on its own. The survey records the exposure of each wall before recommending a material, or recommending against filling.
