There is no single cause of damp. Effective treatment depends on identifying the source of moisture rather than simply addressing the symptoms.
Common causes include:
Condensation
Condensation is one of the most common causes of mould growth in UK homes. It often occurs when warm, moisture-laden air comes into contact with cold surfaces such as external walls, windows and ceilings.
Common indicators include:
Penetrating Damp
Penetrating damp occurs when water enters the building fabric from outside.
Common causes include:
Rising Damp
True rising damp is often misdiagnosed. While it can occur in some buildings, particularly older properties with failed damp-proof courses, many issues attributed to rising damp are actually caused by condensation, high external ground levels or building defects.
Plumbing Leaks
Leaking pipes, defective seals and hidden water leaks can create localised dampness and mould growth which may be mistaken for other forms of damp.
Many homeowners are offered expensive damp proofing treatments before a proper investigation has taken place.
Unfortunately, incorrect diagnosis can result in unnecessary work and considerable expense.
We take a whole-building approach, considering:
By understanding how the building performs as a whole, we can identify the real cause of the problem and recommend the most appropriate remedy.
We will carry out a detailed inspection of the affected areas and the wider property.
The inspection may include:
We will explain our findings clearly and answer any questions you may have.
Following the inspection, you will receive a detailed written report which includes:
Identification of the Cause
We explain exactly what type of damp is present and what has caused it.
Photographs
Annotated photographs help illustrate the defects identified during the inspection.
Recommendations
We provide practical advice on how the problem should be addressed, prioritised and monitored.
Repair Guidance
Where remedial works are required, we explain the most appropriate repair approach.
Evidence for Buyers, Sellers and Landlords
Our reports are often used to support property transactions, landlord obligations and discussions with contractors.
A damp issue identified during a property purchase can be concerning. Buyers are often provided with quotations for extensive damp proofing works without a clear explanation of whether the treatment is actually necessary.
An independent damp survey can help:
Landlords have a responsibility to investigate reports of damp and mould and take appropriate action where necessary.
Our surveys help landlords:
