30 year warranty-badge

Many properties on the market are cheaply damp repaired and newly painted to sell, it’s not until the new homeowners move in and after a few months that the damp and condensation issues start to creep back with horrible mould and damp patches reappearing, occasionally, the extent and severity of the dampness in the property forces residents to vacate while renovations are done and the inside is revamped.

With our most advanced technology London Damp Specialists can find hidden underlying issues that may not be visible to the naked eye.

Nearly every old property has some sort of damp and if it has, we will certainly find it.

Lauren
"Excellent work from Paul and his team. Quote was fair and work was undertaken fairly soon. They protected the floors and tidied up afterwards with barely any sign of them having been in, impressive considering the scope of work done. It's now two months on and no signs of damp. Thanks Paul"

FAQs
Are old buildings more susceptible to damp issues than new ones?

Yes, older buildings are more vulnerable to damp issues than newer ones due to factors like outdated materials, lack of modern damp-proofing, wear and tear, less efficient ventilation, reduced insulation, historic designs, potential foundation problems, and maintenance challenges. Newer buildings are typically constructed with better materials and techniques for damp prevention. However, older buildings can still be protected by addressing vulnerabilities through maintenance and modern treatments.

Do I have to be at home when the work is being done?

As long as our team has access to all parts of the property, there is no need for you to be at home when work is being carried out. All our employees have been vetted and CRB/DBS screened.

Do I have to pay a deposit for damp proofing services?

We do not require payment until the work is dry and you are satisfied with the service.

I am in the process of buying a property in London, should I have a damp survey carried out?

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.

£299 + VAT
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.

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.
