Book a damp survey

or call for help, advice, or to book

If the cause of damp or mould inside a property is unknown, ignoring the problem or painting over the signs of dampness will only allow it to get worse. A damp survey is designed to assess risks to the property’s structural integrity, maintain its value, and safeguard the health of the occupants.

Our damp surveyors will share a detailed independent report after their thorough survey. They have years of experience treating rising damp, penetrating damp, condensation problems, and hidden leaks.

Damp surveys are the right choice for homeowners, landlords, tenants, and homebuyers wanting an accurate diagnosis and to manage potential health risks. Find out why more people in the South East and East of England trust us for their damp and leak problems than anyone else.

Recent customer reviews

A very thorough damp inspection and report. Dean was efficient, honest and on time. Everything was explained in simple terms and he didn’t try to sell us something that we didn’t need.

Helen, Maidstone, ME17
We've had an ongoing damp and condensation problem. The roof specialist that came was brilliant, went in the loft, listened to all the issues/works we'd had done, gave advice and was so helpful. I wouldn't hesitate to recommend the service from Aspect.

Linzi, Crawley, RH10
Khalifa was extremely efficient, professional, and adept at isolating both rising damp and external damp coming from the rendering on our building. He has provided peace of mind and confidence in identifying the issues that need to be resolved. I would not hesitate to use Aspect again. Great work!

Nathan, Chobham, GU24
I called Aspect on Monday afternoon to arrange for someone to visit to assess damp areas in a commercial property. An appointment was arranged for early the next morning. Ahmed called in the morning to let me know his arrival time, and he carried out a very thorough inspection and assessment of the cause of the damp.

Paula, Brentwood, CM15
I phoned Aspect due to a damp issue. Ben Smith arrived later that day and had the situation in hand. He is very knowledgeable on this subject, and I felt reassured after his report. He highlighted the issues clearly in his report, which has proven really helpful to us.

Richard, Caterham, CR3
Connor came out to assess damp in our property, and he was fantastic. He isolated the issue but did a thorough check throughout the house to determine if there were any other issues. I would highly recommend his services and will be using Aspect again when required.

Rikki, Kingston-upon-Thames, KT4

Damp survey or leak detection investigation?

Damp survey

A damp survey aims to identify and diagnose the presence of excess moisture and dampness within a property. It tries to determine the type of damp present, the extent of the problem, and the cause. The survey also includes recommendations on the processes needed to resolve the issue.

Please note that damp surveys are “non-invasive”, meaning building fabric is typically not disturbed. If further investigation is needed to confirm the cause of the problem, this will be recommended in the report.

Leak detection investigation

While a damp survey aims to identify the extent and source of moisture within a property, it may not be able to pinpoint the exact source of the problem.

In contrast, a leak detection investigation is recommended where an active leak is suspected. Using a series of trace and access methods to pinpoint the suspected source of a leak or water ingress, the aim is to stop the leak after exposing it for visual confirmation.

When a leak investigation is recommended

When there is water dripping
When pressure loss is detected in a plumbing or heating system
When the area of water damage gets worse after a bathroom or toilet is used
When water bills are higher than expected
When a significant moisture patch or water staining has appeared quickly

Our experts are ready to answer any of your questions about booking either a damp survey or a leak detection investigation.
