Existing insulation and guarantee check for Fleet properties

If your property is in Fleet or the GU51 district or nearby Farnborough, Aldershot and Yateley, it is within our Hampshire coverage. It is roughly 36 miles north-east of Southampton.

Where a Fleet wall shows cold patches or damp, the survey targets those areas first rather than sampling at random. Buyers and sellers in Fleet often book this check when a survey report or EPC raises questions about the walls.

Wind-driven rain is the first thing the surveyor weighs up. 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.

For regulations, if cavity wall insulation follows in Fleet, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
