Damp and Timber Reports: Key Considerations Before Hiring a Specialist

Buying a property in the UK is, of course, a major step and due to the wet climate, dampness can cause serious damage to a building. Timber is at risk of woodworm, wet and dry rot and prior to making an offer for any property, it is advisable to have tests carried out by a qualified damp surveyor.

At London Damp Specialists, we provide a range of professional services to detect signs of dampness and moisture damage to give you accurate data on the condition of a target property.

Here are a few key considerations to take into account before hiring a damp specialist.

  • Research the provider – Make sure you choose an established company that uses fully qualified damp surveyors. At London Damp Specialists, we have teams of qualified surveyors who take great pride in their work. We have many positive customer testimonials that show we are at the top of our game; we understand that people have schedules to meet and we can communicate with our surveyors in real time when they are in the field.
  • Choosing the right type of survey – We offer a homebuyer damp survey that has 3 different levels, ranging from an inspection of all exterior and interior walls and floors to a comprehensive survey that involves the use of thermal imaging, borescope cameras, testing the air for humidity and a ventilation flow test. There is an additional test that looks for moisture in plaster; up to 10 plaster samples are taken, looking for a source of moisture. We also offer an independent damp survey for those who want a professional opinion without any conflict of interest. Simply fill in our online form or call 020 8528 3864 and the process can begin; our surveyor will contact you to arrange a date and time when they can visit the property in question and you should receive the surveyor’s report within 24 hours of the survey completion.
  • Timely service – Once you decide to go ahead and have a property surveyed looking for signs of dampness and moisture damage, you want a timely service and at London Damp Specialists, we work to the customer’s schedule. You should receive the surveyor’s report within 24 hours of the survey completion. The length of time it takes to carry out a survey very much depends on the size of the property.

We hope that the above information helps you to make an informed decision and if you are planning to buy a property in London or surrounding areas, we strongly recommend that you order our homebuyer damp survey, which is the only way to be sure that the structure is not compromised by dampness and timber damage.

Having a damp survey carried out by a qualified surveyor can also help your mortgage application, as it proves that the structure has not been compromised by rising damp and the timber is in good condition.

 Survey Add Ons

£299 + VAT
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.

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.
