Common Signs You May Need a Damp Survey
You may benefit from a professional damp survey if you have noticed damp patches, peeling paint, musty smells, black mould, staining, condensation, or moisture around skirting boards and external walls.
In many London homes, these symptoms can have more than one possible cause, so a survey helps identify whether the problem is likely to be rising damp, penetrating damp, condensation, leaks, or poor ventilation.

What to Expect from Our Damp Surveys in London
When you book a free damp survey, one of our qualified damp specialists will visit your London property at the arranged date and time to inspect the areas of concern.
During the survey, we will look for visible signs of damp, assess the extent of the problem, and take moisture readings where appropriate. This helps us understand whether the issue may be linked to rising damp, penetrating damp, condensation, leaks, poor ventilation, or another moisture-related cause.
Once the likely cause has been identified, our surveyor will explain the findings clearly and advise on the most suitable next steps. Where remedial work is required, we will provide a clear, no-obligation quotation outlining the recommended method of repair.
As part of the inspection, our specialists will also look out for signs of damage that may have been caused by ongoing moisture, including affected plaster, timber decay, staining, salt contamination, or areas that could deteriorate further if left untreated.

Why and When Should You Book a Damp Survey?
It is worth booking a damp survey as soon as you notice signs of a possible moisture problem in your property. Damp patches, peeling paint, staining, mould growth, musty smells, or moisture around walls and skirting boards can all be signs that something needs investigating.
Some London homeowners arrange a damp survey shortly after moving into a property, particularly if the building is older, has a basement, or has previously shown signs of moisture. Others contact us once they have noticed visible damp, condensation, or damage starting to appear.
The sooner a damp issue is assessed, the easier it is to identify the likely cause and prevent the problem from becoming more serious. Left untreated, damp can lead to damaged plaster, timber decay, mould growth, poor indoor air quality, and more costly repairs.
Our qualified damp specialists can inspect the affected areas, explain what may be causing the issue, and recommend the most suitable next steps. Whether the problem appears minor or has already spread, a professional survey gives you clear advice before you commit to any remedial work.
Common Problems Identified During Damp Surveys
A professional damp survey helps identify the likely cause of moisture problems within your property. Damp can appear for several reasons, and the right solution depends on understanding what is happening before any remedial work is recommended.
Rising Damp
Rising damp occurs when moisture from the ground travels up through walls, often due to a missing, failed, or bridged damp proof course. It can lead to staining, damaged plaster, salt deposits, peeling paint, and damp skirting boards. If rising damp is suspected, our surveyor will assess the affected areas and recommend the most suitable treatment.
Penetrating Damp
Penetrating damp is usually caused by water entering the property from outside. Common causes include defective brickwork, damaged pointing, leaking gutters, cracked render, faulty flashing, or issues around windows and doors. During the survey, we look for external defects as well as internal signs of moisture damage.
Condensation and Mould
Condensation is one of the most common causes of damp and mould in London homes, particularly in flats, older properties, and rooms with poor ventilation. Black mould, streaming windows, musty smells, and moisture on cold surfaces can all point to condensation-related issues. Where condensation is the likely cause, we can advise on ventilation improvements and moisture control.
Basement and Cellar Damp
Basements and cellars are naturally more vulnerable to moisture because they sit below ground level. Damp patches, water ingress, salt contamination, and musty smells can all indicate the need for professional assessment. Depending on the cause, recommendations may include basement waterproofing, drainage systems, or other suitable remedial measures.
Timber Decay and Dry Rot
Long-term damp can affect timber within a property, including floorboards, joists, skirting boards, and structural timbers. If timber remains damp for too long, it may become vulnerable to wet rot, dry rot, or other forms of decay. Our specialists can look for visible signs of timber damage during the inspection and advise if further timber investigation is needed.
Damaged Plaster and Finishes
Damp can cause plaster to break down, paint to blister, wallpaper to peel, and salts to appear on wall surfaces. In some cases, affected plaster may need to be removed and replaced as part of the repair process. A survey helps establish whether the damage is cosmetic or linked to an ongoing moisture problem.
