A stain or musty smell can be a reason to investigate, even when there is no visible puddle. Watch the short guide, then use the points below to describe what you have noticed. These signs are possible indicators, not a diagnosis.
Look for a pattern, without disturbing materials
Stains, watermarks, swelling skirtings, bubbling paint, soft flooring and persistent odours can be associated with moisture. They can also have other causes. Note where the change is, whether it is growing and when you first noticed it. A higher water bill may be useful information for a plumber, but it does not identify the cause by itself.
Take photographs only from a safe position. Do not cut into a wall, lift affected flooring or enter a ceiling space to investigate a suspected leak. Keep clear of sagging ceilings and water near electrical fittings.
Source repair and restoration have different roles
A suitable plumber can investigate and repair a plumbing leak. Roof, building-envelope or other sources may require the appropriate trade. Reztor assesses affected materials and moisture conditions and discusses the restoration work that may be needed. Tell the team if the source is still active or repairs have already been arranged.
Finding and repairing the source does not establish that the surrounding materials are dry. Equally, drying cannot prevent a continuing source from wetting them again. The source and the resulting damage need to be considered together.
What an assessment can establish
Inspection and moisture readings help identify affected areas and guide further checks. Thermal imaging shows temperature patterns; suspected moisture needs appropriate confirmation, such as a moisture-meter check. Readings are interpreted for the materials and conditions rather than against a single universal number.
Ask what is known, what still needs investigation and whether monitoring or controlled drying is appropriate. If there is recurring mould, mention it before disturbing or cleaning the area.
