Damp investigation after cavity insulation for Wilmslow properties
Our Cheshire coverage takes in Wilmslow (SK9) and nearby Macclesfield, Congleton and Northwich. It is about 29 miles east of Chester.
Damp in an insulated Wilmslow home is not always the insulation's fault, so the diagnosis comes before any extraction. We never cold-call in Wilmslow or anywhere else, and we do not work with doorstep claims companies.
Wind-driven rain is the first thing the surveyor weighs up. Cheshire 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 the rules side, if cavity wall insulation follows in Wilmslow, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

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.
