Damp investigation after cavity insulation for Cheltenham properties
Cheltenham sits in Gloucestershire, roughly 7 miles east of Gloucester. We work across the GL50 district, including nearby Tewkesbury, Gloucester and Stroud.
If your Cheltenham installation has a guarantee, we check it first; the guarantee route may cover the work. Where a Cheltenham wall does need work, bricks are lifted and rebuilt in matching mortar, and the cavity is checked with a camera before it is closed up.
Wind-driven rain is the first thing the surveyor weighs up. 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.
For regulations, if cavity wall insulation follows in Cheltenham, 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.
