What Is A Property Damp Survey?

Buying a house is a big financial and emotional step so it is important to take every possible step to avoid problems. If you are applying for a mortgage to buy a property, the lender will complete a mortgage valuation survey but this is cursory and does not give an in-depth report on all the possible problems with the property.

Asking a charted surveyor to perform a full survey will help you in making your decision about whether to go ahead and buy. However, a house survey does not include a damp survey. As damp is a common problem with homes in the UK, it is a good plan to get a damp survey as well as a full house survey before committing to a property purchase.

It is often the case that a normal property survey will pick up a damp problem that needs further investigation and this is the point to bring in a specialist. You may also want to ask for this extra survey as a precaution. Below you will find some answers to frequent questions about damp surveys and information about the different kinds of damp and what damage it can cause.

Property Damp Surveys

Many homes in the UK suffer from problems with damp and unless it is treated it can only get worse and may cause serious damage which can spread throughout the house. It is estimated that 4% of UK properties suffer from some kind of damp problem so this is an issue that should not be neglected or put off to a later date.

A damp survey is carried out by a specialist who is trained to find any problem areas and can advise you how much it will cost to correct any problem. The survey specifically reports on areas in the property where damp could be present. The surveyor may find small spots of damp and mould on a ceiling and this could be due to something as simple as a loose roof tile or inadequate ventilation. Alternatively, damp could be a real problem causing loose plaster or rotting roof timbers. Getting a damp survey will reveal any small or large damp problems.

Damp Survey FAQ

What Are The Benefits Of A Damp Survey?

A detailed damp survey will show up both current and potential future problems. Even small spots of damp can go on to cause major issues and can spread to every room in the house. If you are buying a property a damp survey will enable you to make an informed decision about whether to continue with the purchase.

Do I Need A Specialist To Carry Out A Damp Survey?

A surveyor who has specialised knowledge about damp will be able to give you a report that highlights any issues with damp and how much of problem it is. The surveyor will use the appropriate tools to measure the level of damp and will check all areas of the property.

Where Can I Fine A Damp Surveyor?

A chartered surveyor may also be a specialist in damp surveys. Choose an approved damp surveyor who has a CSRT (Certificate In Remedial Treatment) or a CRDS (Certficate In Remedial Damp Surveying). The RICS website lists accredited damp surveyors.

What Kind Of Damp Problems Could There Be with A Property?

There are three different kinds of damp that can cause damage to a property.

Rising Damp

If the house does not have a damp course there can be rising damp. This can be expensive to correct. Properties built after 1875 will usually have a damp course but older properties probably won’t have one. It might be that there is a damp course but it is damaged and getting a damp survey will reveal the exact nature of the problem.

Condensation Problems

Condensation caused by poor or inadequate ventilation can cause problems with damp. This is the easiest type of damp to fix and does not necessarily require an expert. Simple steps like opening windows, fitting air bricks and air vents or roof ventilation tiles will help to prevent a build up of condensation in the home. Of course, these measure can result in a loss of heat so getting expert advice is still a good idea. The main areas for condensation are kitchens and bathrooms so plan to tackle these rooms first.

Penetrating Damp

Getting rid of penetrating damp caused by leaking or wet walls can be tricky so a professional will be the best person to go to for advice. Poorly fitting windows or broken guttering can cause penetrating damp as can old porous bricks. There may be a problem with the cavity wall and a damp survey by an expert will be able to identify exactly where the fault lies.

How Long Does A Damp Survey Take?

Although most damp surveys can be completed within three or four hours, it may take longer for the surveyor to establish the exact cause of the problem. The time taken also depends upon the size of the property and the degree of the damp problem. The surveyor will ask some questions about the history of the property and then go on to locate the underlying cause of the damp. Specialist equipment and examination of the areas of damp will help the property surveyor to complete the report.

What Does A Damp Survey Show?

A damp report is simple and will point out the areas that have been inspected and any defects that are the cause of the damp issue. Any missing roof tiles or damage to the external area of the property will be included in the property survey report. It will also show if there are any gaps around windows or damaged flashing. Any damp caused at ground level will be shown and the report will offer solutions and potential costs for rectifying the problem.

How Much Does A Damp Survey Cost?

A report on a typical 3 bedroom detached house can cost upwards of £150. The cost rises if the property is a lot larger and costs can also depend upon the location. You will be paying for the advice of a qualified damp surveyor but bear in mind that the cost of a property survey can be minimal compared to the cost of rectifying severe damp damage further along the line.

What Kinds Of Properties Need A Survey?

Any property that has not been maintained properly can suffer from damp problems. If a property does not have a damp course or has obvious telltale signs of damp then it is a good idea to get a damp survey. Left untreated damp not only causes damage to a property but can be hazardous to health with bacteria and mould causing illness especially to anyone with a chest condition.

How Can I Tell If My Property Needs A Damp Survey?

It is easy to spot if your property is suffering from damp problems. If you experience a musty smell or see any small spots of mildew or mould, these are sure signs of damp. Walls and floors that feel cold to the touch and any discoloured patches on walls are also indications of an imminent problem with damp. If you have wallpaper and it starts to peel or if the windows are dripping with condensation, this is also a sign that the property is damp.
