Frequently asked questions
Useful answers before you book.
How do I know what type of damp I have?
Similar marks can have very different causes. An assessment considers the position of the moisture, ventilation, external defects and the construction of the property before treatment is recommended.

Can I request a free quotation?
Free quotations are available for clearly defined remedial works. A professional damp survey with written findings and recommendations is £220 + VAT.
Do you also complete plastering and decoration?

Start with the symptoms
Property problems rarely have a one-size-fits-all answer.
Tell us what you can see, smell or feel. We will help identify the likely source before recommending a repair.
Damp patches or staining
Marks on internal walls can relate to rain penetration, plumbing, condensation or moisture rising through the structure.
Mould and condensation
Persistent window moisture, black mould and musty air may indicate excess humidity, cold surfaces or inadequate ventilation.
Peeling paint or damaged plaster
Flaking finishes and salt deposits are often symptoms. The underlying moisture source should be addressed before redecoration.
Water entering a basement
Below-ground areas need a waterproofing approach suited to the building, intended use and level of water pressure.
Soft or affected timber
Timber defects should be assessed alongside the moisture conditions that allowed damage to develop.
Cracks or movement
Cracking varies widely in significance. A careful inspection helps determine the appropriate next step.
