Cavity wall suitability survey for Newport properties

Newport is among the towns we cover in Gwent, alongside Risca, Cwmbran and Pontypool. Newport is one of the main towns we cover in Gwent.

A survey in Newport gives you facts before anyone drills: what the wall is, what is in the cavity and whether it is sound. Buyers and sellers in Newport often book this check when a survey report or EPC raises questions about the walls.

Local weather affects which walls can be filled. Parts of Gwent face some of the heaviest wind-driven rain in the UK, especially exposed coastal and upland sites. Here the survey is stricter: some walls suit only certain certified systems, and some should not be filled at all.

On the rules side, in Newport filling a cavity is notifiable work under the Building Regulations as they apply in Wales, usually self-certified through a competent person scheme.

Cavity wall suitability survey in Newport: questions

Is my Newport home too exposed for cavity insulation?

Parts of Gwent get some of the heaviest wind-driven rain in the UK, so the survey is stricter and some walls are better left unfilled. The survey records the exposure of each wall before recommending a material, or recommending against filling.

Which building regulations route applies in Newport?

Newport is in Wales, so filling a cavity is notifiable work under the Building Regulations as they apply in Wales, usually self-certified through a competent person scheme. We confirm the route in writing on your quote.

How soon can you visit in Newport?

We arrange dates when you get in touch. Availability varies through the year, so we give you real dates rather than a promise on the website.

Do you cold-call in Newport?

No. We only come out when you have asked us to. If someone cold-calls offering free insulation, check before you agree to anything.
