HOMEBUYERS DAMP SURVEY

certification

Damp can easily be concealed with a skim of plaster and a few coats of paint and when buying a London property, it is essential that you have the building inspected for damp, mould and timber rot before you make such a commitment. The worst-case scenario is to acquire a property, then discover there are damp issues, which could cost thousands of pounds to repair. It could be several months before the damp issues become apparent, by which time, significant damage has been caused.

At London Damp Specialists, we use cutting edge technology to assess a building for damp, mould and timber rot and if there are any issues, we will definitely find it.

Homebuyer Survey Details

Our homebuyer damp survey has 3 levels, which are as follows:

Damp-Proof-Course
survey-bronze icon

Level 1 Damp Survey

A thorough inspection of exterior and interior walls, floors, and ceilings to identify tell-tale signs of rising or penetrating damp.

The survey includes damp detection and inspection of all walls and floors, as well as leak inspection of drains and water pipes to locate possible sources of moisture. Designed for buyers and sellers, it determines the presence of damp, mould, and timber rot.

Level 2 Damp Survey

Everything included in Level 1 plus a closer examination of structural components such as joists, rafters, window frames and door frames.

The surveyor also carries out a detailed dry/wet rot and woodworm inspection to identify any timber decay. If issues are found, we can recommend a trusted London damp-proofing contractor to carry out the required work.

Level 3 Damp Survey

Our most comprehensive survey. Level 3 includes everything from Levels 1 and 2 plus an advanced set of diagnostic tests.

This survey uses thermal imaging and air humidity testing to identify hidden moisture issues, along with an HD borescope camera for checking loft spaces, cavities and other hard-to-reach areas. We also carry out a full brickwork pointing inspection, DPC inspection, and a ventilation flow test on extractor fans to assess airflow and mould risk. For external parts of the property, we include 4K drone imagery to inspect the roof, chimney stack and guttering safely and in high detail. All Level 3 surveys are non-invasive and cause no damage to the property.

Plaster Analysis

An additional service we offer is up to 10 samples of interior plaster, which we test for moisture content to give you a definitive assessment.

This is the best way to accurately measure moisture content within walls; results come through quickly and are part of a detailed report that would include images and maybe video.

Mould Lab Swab Testing

We offer professional qPCR mould swab testing, which analyses DNA from a surface swab to detect and quantify specific types of mould present within the property (up to 100 square metres).

This laboratory-grade test provides highly accurate results and is ideal for confirming the presence and severity of mould growth.

Cutting-Edge Digital Equipment Our Surveyors Use

At London Damp Specialists, our independent damp surveyors use the following equipment to accurately assess London homes:

Damp Meter

This multi-functional device measures moisture both on surfaces and inside building materials. The pinned variety is used to measure moisture levels within timber, cement and plaster, while the pinless variety measures moisture content on surfaces. Every damp surveyor would carry at least two damp meters, with one as a backup.

Humidity Tester

A hand-held device to measure the level of moisture in the air, a humidity tester has a digital readout that helps the surveyor determine the level of moisture inside the building. In the event the damp inspector is looking for mould, they would use the humidity tester to find potential areas where mould could be present. This is one of the first pieces of kit a surveyor would use when entering a building.

Infrared Camera

The use of thermal imagery enables the surveyor to clearly see both dry and moist areas. The camera uses colour to visualise temperature differences on building materials, with red a higher temperature than blue. This device is mainly used for masonry diagnosis and it is an essential item for every independent damp surveyor.

Pinhole Camera

Also known as a borescope camera, this handy device gives the surveyor a close up look in all those hard-to-reach places, such as dark corners of the loft, under floorboards and inside cavity walls. Without this device, it would not be possible to see in specific locations where damp and mould might be present.

Ventilation Airflow Test

A hand-held device with a moving fan that accurately measure air movement. Ventilation is critical when it comes to the prevention of mould formation; a still and damp atmosphere is one in which mould can thrive and one of the first things the surveyor would do is use this device in numerous locations around the house to get a clear indication of natural airflow.

Drone imagery

Our surveyors are very competent drone operators and they can get close-up views of every square inch of a roof, looking for missing or dislodged roof tiles, blockages in guttering and other potential issues. High-resolution images are captured to show the customer problems, while the drone is also used to inspect upper external walls.
