Cavity insulation top-up in Bordon

For homes and buildings in Bordon, cavity insulation top-up is arranged survey-first: we check the property, tell you plainly what we found, and price it. A cavity top-up fills voids left by an older installation: missed panels around windows, settled fibre, areas disturbed by an extension or new window.

Cavity insulation top-up for Bordon properties

If your property is in Bordon or the GU35 district or nearby Aldershot, Fleet and Farnborough, it is within our Hampshire coverage. It is roughly 27 miles north-east of Southampton.

A suitable wall in Bordon is usually filled in a single day from outside, with drill holes made good to match the pointing. If a wall in Bordon is not suitable, for example because of an undiagnosed damp patch or a very exposed gable, you are told so in writing with the reason.

Exposure matters for every cavity wall. 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.

On compliance, in Bordon filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

When a top-up is not enough

If the existing fill is wet, contaminated with debris or breaking down, adding more on top can make things worse. In that case we tell you the honest option, which may be partial or full removal and refill.
