What Does a Damp Survey Involve? 

What does a damp survey involve? If you’re moving into a new home, looking at renovating your current residence or are a landlord who is letting to tenants, a damp survey carried out by professionals could save you a lot of money in the long run.  

By the time damp and mould present themselves in your property, the problem can be major. Therefore, prevention of the issue is less costly and will take less time than trying to fix the problem once it is established.  

A damp survey is a cost effective way of making sure your property is clean, dry and a healthy place to live in. Property Damage UK can help with this type of service.  

Damp Surveys: What Do They Involve? 

It’s important to enlist the help of professionals and find independent damp surveyors to assess your property. On arrival the damp surveyor will take a walk around the outside of a property. This is so they can assess the construction of the building. They will be looking for the following: 

  • Whether or not the walls are solid 
  • Whether or not the walls are cavity 
  • Whether or not the walls filled with rubble 
  • Whether or not there is an effective damp course present 

The general design of the house will be taken into account, as will the lie of the land which surrounds it. The following factors (depending on the type of property being surveyed) will be looked at: 

  • Is the house on a slope or not? 
  • What is the height of the slope in relation to the internal floors of the property?  
  • Are there features of the house which need regular maintenance, for instance valley gutters; copings on verges, rainwater pipes; surface water drains; any other walls that intersect the house such as boundary or retaining walls.  
  • Are there chimney stacks? 

A professional will assess these factors then look for defects.  

  • What’s the pointing like?  
  • What’s condition is the render in? (e.g. is it cracked or hollow, or is it in contact with the ground?)  
  • What condition is the guttering and/or downpipes in?   
  • If there is a damp proof course, is it bridged?  
  • Do the extractors in the kitchen or bedroom have vents or ventilation cowls? 
  • Are the bricks or stone that the property is built from porous?  
  • Are there bushes or ivy which could block gutters and potentially conceal other issues?  


This list is by no means exhaustive, but it provides a few useful pointers to bear in mind before contacting someone to do a professional damp survey on your home or building.  

Internal Damp Surveys  

After the exterior of the building has been considered, the interior of the building will then be examined. The surveyor may have an initial chat with the property owner to see if there is anything known about the history of the house and what (if any) works have been carried out on it by them.  

Usually a surveyor will have a good idea of where any damp issues are likely to be from simply walking round the property and looking at it from the outside.  

Initially, a visual walk round will be needed to look for simple signs such as stains, loose wallpaper, peeling paint, salting or signs of mould. Then ultrasound and/or thermal building inspection equipment will be used to check walls where damp could possibly be occurring but hasn’t made it through to the decorated surface of the wall yet.  

If there is a visual problem or technical equipment has given an elevated damp reading the surveyor should then check to see if the problem is an old one, which has dried out.  

If it isn’t dried out and high damp readings are obtained, then the surveyor will thoroughly profile the area to find out what the distribution of moisture is. This profile will help with the overall diagnosis of damp, when combined with what they have found with both the internal and external inspections of the property.  

Damp Survey Reports 

A full written damp survey report will be given, so expect the surveyor to be taking notes and photographs throughout the time he is at the property.  

The report will contain recommendations as to what to do (if anything) about the damp and will for the backbone of the survey. There might be recommendations such as simple maintenance work, perhaps re-pointing, installing or replacing extractor fans or repairing gutters, down-pipes or in some cases re-roofing.  

In certain circumstances the cause of the problem may well be rising damp or a severe penetrating damp issue or if your house or property has a cellar something called damp under hydrostatic pressure which refers to damp in spaces below ground level. A professional damp surveyor will prepare a damp report based on their recommendations for the work that needs to be carried out.
