Damp investigation after cavity insulation for Horsham properties
If your property is in Horsham or the RH12 district or nearby Crawley, Haywards Heath and Burgess Hill, it is within our West Sussex coverage. It is around 7 miles south-west of Crawley.
We never cold-call in Horsham or anywhere else, and we do not work with doorstep claims companies. Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for Horsham properties, so you can choose who fixes them.
Local weather affects which walls can be filled. West Sussex 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 Horsham, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
