“Excellent service throughout. Ashton came out to look at an issue raised on a part-exchange survey and, rather than recommend expensive remediation, told me honestly there was nothing wrong with the wall. Great to have an honest discussion.”

Areas we cover near Southampton
Our specialists regularly work throughout Southampton and the surrounding neighbourhoods.
Why Southampton homes suffer from rising damp
Southampton’s Victorian terraces and inter-war homes, many close to the Itchen and Test estuaries, are particularly exposed to ground moisture.
Victorian terraces
Terraces in Shirley, Portswood, Freemantle and Polygon frequently have failed or missing DPCs, leading to damp, salts and blown plaster on ground-floor walls.
Wet estuary ground
Low-lying areas near the rivers and docks have higher ground moisture, which puts extra pressure on older damp proof courses.
Extensions & alterations
Poorly detailed extensions and replastering with gypsum can bridge or hide a damp proof course, causing damp to reappear at junctions.
How we treat rising damp in Southampton
1. Survey & diagnosis
Calibrated moisture readings, salt analysis and a check of ground levels confirm genuine rising damp — and rule out condensation or penetrating damp.
2. New damp proof course
A chemical DPC is injected into the mortar course, or where the wall needs it, our Proofterior Dry System (PDS) membrane is installed.
3. Salt-resistant replastering
Salt-contaminated plaster is removed and replaced with a specialist renovating plaster, leaving a smooth, dry wall ready to decorate.

Usually, yes. Rising damp leaves salts in the old plaster that keep drawing moisture from the air. Replacing it with a salt-resistant renovating plaster is essential for a lasting result.
