Existing insulation and guarantee check for Basingstoke properties

If your property is in Basingstoke or the RG21 district or nearby Fleet, Yateley and Aldershot, it is within our Hampshire coverage. It is about 29 miles north-east of Southampton.

The written result for your Basingstoke property is plain English: what we found, what it means and what, if anything, to do next. Where a Basingstoke wall shows cold patches or damp, the survey targets those areas first rather than sampling at random.

Local weather affects which walls can be filled. Hampshire 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.

In terms of approvals, if cavity wall insulation follows in Basingstoke, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

How to tell if a house already has cavity insulation

Look for a regular pattern of small patched holes in the mortar joints, often about a metre apart. Check the EPC, which may say 'filled cavity'. Ask the seller for a guarantee. The reliable answer is a borescope check, because patched holes can be from a fill that was later removed and EPCs are sometimes wrong.
