  • Importance of Damp Surveys: Damp is acknowledged as a prevalent and discomforting issue in UK homes, posing both aesthetic and health risks. The importance of getting a professional damp survey is stressed, ranging from minor damage like water stains to severe issues such as structural decay.
  • Damp Survey Process and Cost: The content describes the damp survey process, indicating that it involves mapping moisture patterns, utilizing specialized equipment, and producing a detailed report.

Structural damp is the presence of unwanted moisture in a building structure, resulting either from infiltration from the outside or condensation from within the structure.  A large proportion of damp problems in buildings are caused by factors dependent on the ambient climate, such as condensation and rain penetration. 

The capillary penetration of liquid from bottom to top through concrete or masonry is known as “elevated humidity” and is determined by the shape and porosity of the building materials through which this evaporation-limited capillary penetration occurs.  Another cause of damp is thermal bridging.  Because of thermal bridges, mould is most likely to appear in the corners of walls and at the floor-wall junction.  A thermal bridge is a point or linear area that exhibits a change in thermal resistance in the building envelope.  Structural dampness, regardless of the mechanisms by which it occurs, is exacerbated by higher moisture levels.

Moisture control is fundamental to the proper functioning of any building.  Humidity control is important to protect occupants from adverse health effects and to protect the building, its mechanical systems, and its contents from physical or chemical damage.

The mention of “damp” often causes discomfort for numerous homeowners. Even though it is a prevalent issue in the UK, dealing with it is never a pleasant experience. It looks destructive and poses serious health risks if exposed to damp for long time periods.

You should get a professional damp survey done if you discover any signs of damp in your home or a home you’re buying. Damp problems can range from minor damage, such as a few penetrating damp patches of water stains or mould, to significant damage, such as structural decay and crumbling plaster.

So let’s get into the details surrounding Damp Survey Costs…(How much does a Damp Survey Cost)

What is a Damp Survey?

A qualified damp specialist conducts a damp survey to discover any damp areas on your property. They will include a comprehensive inspection of the property and utilise specialised equipment to assess the severity of the issues.

Various forms of damp may be captured in the survey. Each one necessitates a somewhat different treatment approach. A damp survey will determine whether you have damp, what type of damp you have, and how to treat it.

You should ensure the surveyor is a Certificated Surveyor of Timber & Damp in Buildings or CSTDB qualified professional. You can then be confident they will inspect the property for symptoms of damp and assess the extent of damage caused, and estimate the cost of any remediation work that may be required.

A general property survey will look at the overall state of the structure, whereas damp surveys will look at the type of damp present and the damage it has caused to the property.

What does a Damp Survey Involve?

A damp survey aims to map the moisture patterns within the walls and other building elements. The resulting survey will show how moisture moves through the damp walls, floors or other areas to clearly identify which areas need treating and which areas need protecting from future potential damp issues.

The damp survey report developed will enable the client to understand the damp issues in technical detail, along with the severity of the issue and how it should best be treated.

The damp surveyor will use a damp meter to inspect the house and search for telling visual clues. They’ll look for areas of wet plaster, wood rot, rising damp issues, around windows for condensation, and other areas of potential damp problems.

Finally, they’ll prepare a report that includes recommendations for treatment.

How Long Does a Damp Survey Take?

Typically, a damp survey can take anything from 2-3 hours to complete.

The time of a damp survey, on the other hand, is determined by several factors, including the type of damp that is prevalent, the size of your home, and the severity of the issues discovered, including broken roof tiles, faulty guttering, wet skirting boards or other signs of water damage.

Nonetheless, the survey will always cover the entire property to investigate potential hidden signs of damp, not merely focusing on the known areas of concern.

How Much Does a Damp Survey Cost?

The size of your home will determine the cost of a damp survey. The more rooms and the larger the home, the longer the damp survey will take to survey and the higher the cost.

Equally, consideration has to be taken for specifics relating to the business carrying out the damp survey – for example; distance travelled and any other fixed costs they may have to build into their fee. Some indicative costs are below…

A damp survey for a two-bedroom property will start at around £200, but it may be increased to £300-400 if you have a four-bedroom house. And depending on the conditions, a damp survey for a larger 4-bed detached house may cost around £500-600.

Apart from the size of your house, other factors influence the cost of the damp survey. Certain parts of the UK are more expensive than others, and where you live will have a significant impact. For instance, London and the South East of England will be more expensive.

A damp and timber survey is also available, which some mortgage lenders may require you to complete. The damp and timber survey cost will set you back roughly £200 to £300.

Based on the figures mentioned, you could be forgiven for supposing damp surveyors get paid so much for one or two hours’ labour. Fortunately, this is not the case. The damp surveyor will spend several hours producing a damp survey report once they get the information from the survey itself.

The Bottom Line on Damp Survey Costs

You should now know the damp survey costs and the process involved. The key thing to identify is that an accurate diagnosis of the type and severity of damp your property is experiencing is key to ensuring correct damp treatment can be undertaken.
