Ordering a Damp Survey of your London Home – The Process Explained

Ordering a Damp Survey of your London Home – The Process Explained

3rd July, 2025

At London Damp Surveys, we have been assisting London homeowners and potential buyers by providing accurate inspections primarily looking for damp, mould, condensation and timber rot. In this short article, we outline the inspection process to give you a clear indication of what to expect when you commission a survey from London Damp Surveys.

Initial enquiry

You can either call us on 0207 305 5997 or fill in the form on this website; when you call, one of our staff will ask you for the following information:

  • Full name & address of the property to be inspected (with postcode)
  • Email address and telephone number
  • Choose one of the customer types

One of our certified damp surveyors will contact you to arrange a suitable date and time to carry out the inspection. We always try to fit in with the customer’s schedule and can usually complete the inspection within a few days of receiving the initial enquiry.

Carrying out the damp inspection

The surveyor requires full access to all areas of the property and the customer does not need to do anything regarding preparation. In the event you are not able to be at home when the survey occurs, that is not an issue, as long as someone is there to allow access. A survey takes on average 2-3 hours to complete, which would include a roof inspection using a drone; it is necessary to closely inspect the roof, looking for missing or damaged roof tiles and also the general condition of the guttering. Of course, every property is unique and our surveyors understand this; each would have their own process, which wouldn’t differ that much; they may start at the top and work their way down or they might start at ground level and finish with the roof.

Equipment used in the survey

Our surveyors are certified and use the following equipment:

  • Thermal imaging
  • Moisture meter
  • Rotating anemometer
  • Borescope camera
  • Drone imagery
  • Digital camera

Once the surveyor has completed the inspection, they compile a detailed report, which is sent to the customer via email.

Sourcing a suitable damp proofing contractor

At London Damp Surveys, we carry out damp inspections but do not carry out damp proofing work, however, we can put you in touch with a top-rated damp proofing contractor that we have a working relationship with. They would be happy to provide you with an all-inclusive quote for recommended remedial work and would issue a long-term warranty on all work carried out.

We pride ourselves on the smooth process that our customers enjoy; if you are in need of a damp survey, we are the go-to company that covers all areas of London. From initial enquiry to receiving the survey report, we like to think we provide a service that is second to none.

If you would like a professional damp assessment from a leading London company, call London Damp Surveys on 0207 305 5997 and set the wheels in motion.

 Survey Add Ons

Add On 1

£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.

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.
