We find why the house is wet and fix the ventilation, rather than painting over mould. Covering Plymouth and PL1, PL3 and PL4.

Mould in a Plymouth bedroom or bathroom is almost always a ventilation problem first.
Whether the property is in the middle of Plymouth or one of the villages around it, the process is the same: a look at the building, a written price, then fitting and testing on the agreed day.

What the work involves
Mould needs that damp surface to grow. Ventilation is usually the biggest part of the cure, but not the only part.
Survey and findings
Humidity and surface readings, existing fans flow-tested, and a written list of causes and fixes.
Fan upgrades
Weak or loft-vented fans replaced and ducted outside, with humidity control.
