Damp investigation after cavity insulation for Yate properties
Our Gloucestershire coverage takes in Yate (BS37) and nearby Mangotsfield, Kingswood and Stroud. It is about 24 miles south of Gloucester.
Defects such as failed pointing, leaking gutters and bridged damp-proof courses are listed and priced separately for Yate properties, so you can choose who fixes them. Damp in an insulated Yate home is not always the insulation's fault, so the diagnosis comes before any extraction.
Every elevation is judged on its own exposure. Gloucestershire 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 Yate, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
Rules in England

Common causes we check
Defective pointing, cracked render and porous bricks letting rain in; leaking gutters and downpipes; fill bridging the cavity where mortar droppings or debris have collected; ground levels above the damp-proof course; and condensation from cooking, drying clothes and too little ventilation.
