Cavity wall suitability survey for Renfrew properties

Our Renfrewshire and Inverclyde coverage takes in Renfrew (PA4) and nearby Paisley, Newton Mearns and Greenock. It is roughly 3 miles north-east of Paisley.

The written result for your Renfrew property is plain English: what we found, what it means and what, if anything, to do next. A survey in Renfrew gives you facts before anyone drills: what the wall is, what is in the cavity and whether it is sound.

Local weather affects which walls can be filled. Parts of Renfrewshire and Inverclyde 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 Renfrew no building warrant is needed for insulation within a wall, but the work must meet the building standards.

Rules in Scotland

No building warrant is needed for insulation within a wall, but the work must meet the building standards if insulation work follows.

Sources: Scottish Government: building work not requiring a warrant (schedule 3).

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 Renfrew: questions

Is my Renfrew home too exposed for cavity insulation?

Parts of Renfrewshire and Inverclyde 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 Renfrew?

Renfrew is in Scotland, so no building warrant is needed for insulation within a wall, but the work must meet the building standards. We confirm the route in writing on your quote.

Yes. Renfrew and the PA4 postcode district are within our Renfrewshire and Inverclyde coverage, along with nearby Paisley and Newton Mearns.

Do you cold-call in Renfrew?

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