Damp in your home? Find out exactly what you are dealing with
Damp is not one problem. It is several different problems that look similar but require very different solutions. Our professional damp assessment identifies exactly what type of damp you have, where it is coming from, and what needs to happen to resolve it properly.

What is a damp assessment?
A damp assessment is a professional investigation using specialist moisture-measuring equipment to identify the presence, extent and cause of damp within a property. Damp comes in several forms: rising damp, where moisture travels up from the ground through walls; penetrating damp, where water enters through the building fabric from outside; and condensation-related moisture, which is caused by warm air meeting cold surfaces and is often linked to poor ventilation. Each type requires a different solution. A damp assessment gives you the evidence-based diagnosis you need before committing to any treatment. Without it, there is a significant risk of paying for the wrong treatment and still having the same problem.

Signs of damp to look out for
Damp patches or tide marks on walls, particularly near the floor or external walls
Peeling or bubbling wallpaper or paint
A persistent musty smell in certain rooms
Visible mould, particularly on cold exterior walls
Salt deposits or white staining on brickwork or plaster
Rotting skirting boards or window frames
Condensation regularly forming on windows or cold surfaces
A property that feels cold and damp despite adequate heating
What does a damp assessment involve?
Our specialist visits your property and uses professional moisture meters and thermal imaging equipment to measure moisture levels within walls, floors and ceilings throughout the affected areas. We assess the pattern and distribution of moisture to determine the type of damp present. We inspect external and internal building elements that may be contributing to the problem. We measure humidity and ventilation to understand the full picture. Following the assessment, we provide you with a clear written summary of our findings, including the type of damp identified, its likely cause, and the recommended course of action. We explain everything in plain language so you can make an informed decision about next steps.

Why choose Intra Air for a damp assessment?
Damp is frequently misdiagnosed. Condensation is often mistaken for rising damp, leading homeowners to pay for damp proofing treatments that will not resolve a ventilation problem. Penetrating damp is sometimes attributed to rising damp, and vice versa. Our assessment gives you an accurate diagnosis based on measurement and evidence. We are not tied to any particular treatment or product, so our recommendation is always based on what will actually solve your problem, not what is most profitable to sell you.

Landlords: a proper damp assessment protects you legally
Damp is one of the most common causes of tenant complaints and one of the most frequently disputed issues at end of tenancy. An independent professional assessment that documents the type, extent and cause of damp provides you with evidence of the property’s condition at a specific point in time. Under Awaab’s Law and broader housing health and safety obligations, landlords who can demonstrate they identified, assessed and acted on damp issues are in a significantly stronger legal position than those who did not.
Frequently Asked Questions
Rising damp is caused by moisture travelling upward through the building structure from the ground. It typically appears as a tide mark low on internal walls. Penetrating damp is caused by water entering through the building fabric, often from defective guttering, roofing or pointing. Condensation is caused by warm moist air meeting cold surfaces and is commonly linked to poor ventilation or inadequate heating. Each requires a different treatment, which is why accurate diagnosis matters.
Yes, always. Treating without a proper diagnosis significantly increases the risk of applying the wrong treatment. This wastes money and leaves the underlying problem unresolved.
