“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.
What causes mould in Southampton homes
Southampton has a large rented sector and many older terraces, both of which see high rates of condensation and mould.
Student & rented houses
Shared houses in Portswood and Highfield produce lots of moisture from cooking, showers and drying laundry, often with limited extraction.
Cold, solid-walled terraces
Victorian terraces have cold solid walls and window reveals where condensation forms. Insulated linings like Iso-therm raise the surface temperature.
Hidden leaks & penetrating damp
Some mould is caused by water getting in — failed gutters, chimneys or pointing. We check the building fabric so the true cause is fixed.
How we remove mould in Southampton
1. Find the moisture source
We measure humidity, surface temperatures and moisture levels to work out why mould is growing — condensation, penetrating damp or a leak.
2. Remediate safely
Affected areas are treated with professional anti-microbial products, and badly contaminated materials such as plaster or sealant are removed where necessary.
3. Stop it returning
We fix the cause — Positive Input Ventilation (PIV), humidistat extractor fans, insulated wall linings or repairs to the building fabric.
