DAMP & MOULD SPECIALIST · LONDON
External damp &
water ingress checks.
A stain that worsens after rain may be connected to water entering the building. We inspect the signs of damp inside and look for accessible external defects that could explain them.

UNDERSTANDING THE PROBLEM
Trace the water
back to the building.
Overflowing gutters, damaged joints and gaps around openings can allow rainwater to reach parts of a wall that should stay dry. The point where a stain appears indoors may be some distance from the entry point.
We compare the internal damage with accessible external features and the history of the problem. The aim is to identify likely routes for water and explain which repairs or further checks are needed.
Dates and photographs taken before and after rain can help show how the stain changes. Tell us if the affected wall belongs to a shared part of the building, because access may need to be coordinated. Internal moisture investigation helps connect those external clues to the damage indoors before mould treatment or decoration is planned.

BEFORE YOU BOOK
Questions about
this service.
Is the leak always directly above the stain?
No. Water can travel through the building before becoming visible. We consider the surrounding construction as well as the stained area.
Do you repair roofs and gutters?
This service focuses on investigation. Call to discuss the scope and any repairs needed following the findings.
Can you inspect every part of the exterior?
Access affects what can be checked. We explain any areas that cannot be assessed during the visit and what further access may be needed.
