Rot Problems?

Dry rot, wet rot, penetrating damp, rising damp, condensation: all water-damage problems faced by home owners and all problems that need to be fixed sooner rather than later. But each is a different issue with a variety of effects and treatment methods. One quick call to London Damp Specialists is all it takes to diagnose your damp or rot problem and here’s a quick guide to spot your rot.

Dry Rot

When damp is combined with poor ventilation you have the perfect feeding ground for fungus. The fungus is highly invasive and can affect any type or age of property. It feeds off timbers and quickly spreads into plaster through cracks and cavities. Common signs of dry rot are damaged timbers (often out of sight below floors or in lofts) and visible orange/brown dust before it manifests itself in fluffy white spores and mushrooming spores – the latter stages show an advanced case of dry rot.

How is Dry Rot Treated?

Dry rot needs to be treated professionally and quickly in order to halt any further spread and eradicate it fully. It can be a disruptive process as it involves plaster and timber removal and replacement as well as treatment with a dry rot-resistant solution.

Wet Rot

If there is a constant source of water ingress or a leak from somewhere in the property, wet rot will develop – it could be from leaky plumbing, damaged gutters, downpipes or deteriorated pointing. Whatever the cause, it needs to be sorted! Wet rot isn’t as destructive as dry rot but left unchecked can badly affect timbers, leading to structural damage. If you notice a musty smell, spot fungal growth or distorted or discoloured timbers, you could be suffering from wet rot. It’s important to get it diagnosed professionally, not least to make sure it’s not dry rot, and make sure it is treated effectively and correctly.

How is Wet Rot Treated?

First and foremost, the source of the water ingress needs to be found and stopped. Following that, it must be determined how much wet rot has affected the area and timbers treated accordingly – probably removed and replaced, and new timbers, as well as the surrounding remaining wood, treated with fungicidal solution.

We would always recommend you seek professional help if you suspect your property is suffering from any kind of rot-related damage. Treat it before it becomes a major problem.

Lab Analysis Of Plaster

Laboratory analysis Of plaster identifies hygroscopic salts such as chlorides and nitrates. which indicate whether damp is caused by rising groundwater or by plumbing leaks, This testing removes guesswork, allowing the exact source of moisture to be identified so the correct treatment is applied rather than carrying out unnecessary damp-proofing work.

Mould Lab Swab Testing, qPCR on DNA

qPCR DNA mould testing detects microscopic mould spores that are invisible during a normal inspection and van remain hidden behind walls, floors. or inside building rkaterials. It identifies the exact mould species present and the contamination level, allowing hidden mould problems to be confirrned and properly treated before they affect the property or occupants’ health.

Add to Survey

Qualifications: All our surveyors are PCA and CSRT qualified for remedial treatments and also CSSW qualified for structural waterproofing.
Next day report: You will receive the report within 24 hours of the inspection taking place.

The survey fee will be deducted from the cost of any recommended repairs.

These are the tools we use

A damp meter

A damp meter

A damp meter is a diagnostic tool used to detect and measure moisture levels within building materials such as plaster, brick, timber, and concrete.

Borescope camera

Borescope camera

borescope camera is a small inspection camera attached to a flexible semi-rigid cable that allows you to see inside areas that are otherwise inaccessible.

Inspection Drone

Inspection Drone

A drone is a remotely operated aerial device equipped with a camera that allows visual inspection from above without the need for scaffolding or ladder.

Air Humidity Sensor

Air Humidity Sensor

Air humidity sensor measures the amount of moisture present in the air, expressed as relative humidity (RH) in percentage. It helps determine whether indoor conditions are contributing to condensation, mould growth, or damp-related issues.

Thermal Imaging Camera

Thermal Imaging Camera

A thermal imaging camera detects temperature differences on surfaces by using infrared technology to produce a heat map image. In damp investigations, it helps identify cold spots, moisture intrusion, insulation defects, thermal bridging and leaks.

Air Flow Ventilation Detector

Air Flow Ventilation Detector

An air flow ventilation detector measures the movement and volume of air passing through vents, extractor fans, and air bricks. It confirms whether ventilation systems are working properly and achieving adequate air changes within a room. Poor airflow leads to trapped moisture, high humidity, condensation on cold surfaces, and ultimately mould growth.

Mould Swab Test Kit

Mould Swab Test Kit

A mould swab test is carried out to confirm the presence of hidden mould growth and identify the specific species involved. Surface mould is not always visible, especially behind furniture, inside cavities, or within ventilation systems. Laboratory analysis of a swab sample determines whether active mould spores are present and what type they are, which helps assess potential health risks and decide the correct remediation approach rather than relying on visual assumption alone.

Plaster Salt Analysis Lab

Plaster Salt Analysis Lab

Laboratory analysis of plaster is used to identify the type of salts present within the material, typically chlorides and nitrates. The presence and concentration of these salts help determine whether the moisture source is consistent with rising damp, ground contamination, or another forms [sic] of water ingress. such as mains water leak, This removes guesswork and prevents misdiagnosis, ensuring the correct remedial treatment is specified rather than applying unnecessary or ineffective solutions.
