cost of a damp survey

The cost of a damp survey can vary significantly depending on factors such as the width, height and length of the property, and how many walls need to be tested. It can also depend on whether there is any damage to the structure. Damp surveys are commonly undertaken by construction companies in order to identify where water may have come into contact with areas during building work or due to natural causes, such as flooding or drainage issues. So, how much does a damp survey cost ?

Factors that determine how much a damp survey can cost:

The width, height and length of the property:

This will have an impact on the time spent surveying, which will in turn have an impact on the cost of the survey. A damp survey of a large property will take longer to carry out and therefore cost more than one for a small house.

The number of walls tested:

The walls need to be checked for signs of rising dampness or damage to determine if any repair work is needed. One of the most common causes of damp is poor ventilation, which can occur on upper floor ceilings where old units are not regularly cleaned out.

Assessment of the structure:

This determines whether repairs need to be carried out and can include fixing leaks, raising floors (if damp has gathered under floors) or installing a moisture barrier if applicable to the property.

Itemizing the repairs:

This can include writing up the authors notes and fitting out a report which will show the cost of all maintenance work needed.

Testing after repairs are carried out:

This will allow you to check on whether there has been any short-term reduction in dampness levels, which could indicate that the heating system needs upgrading to protect the property and its contents.

What is a damp survey?

A damp survey is a visible check that advises you whether your property may have been affected by rising damp or water damage in the past. This kind of damp is caused by a buildup of condensation, which can lead to expensive repairs to walls and ceilings.

A damp survey consists of an inspection of the outside and inside walls in both the upper and lower levels for signs of dampness. This includes testing for gaps or holes in the walls through which moisture may have penetrated. The surveyor will also assess the structure to determine whether any repairs are needed and estimate how long it will take to complete them.
