How to identify signs of damp in your house

The earlier you can identify signs of damp in your house then the easier it is to take action and prevent the problem developing further. Our guide will help you spot the signs of the most common types of damp like rising damp, penetrating damp, and condensation.

Damp can affect any building new or old, but typically it can be attributed to poor property maintenance, poor build quality, the use of low-quality materials, or the absence or failure of an existing damp proof course. If you spot any of the signs listed below and feel that you would benefit from professional help, contact our damp specialists on 0800 633 5712 or book a survey using the form below.

What type of damp is in your home

It is essential that you know what type of damp is present in your house to correctly treat it, remove the excess moisture, and ensure that the source of the water ingress has been addressed to make sure that it will not return.

Below we have outlined the most common signs of the main types of damp. The following tell-tale signs of damp are the key indicators of each of the different types, but even with this help and guidance, without the knowledge, experience and qualifications of a certified surveyor, it can be very difficult to accurately identify the exact cause of damp walls in your house.

How to solve damp in your home

For less severe or easily identifiable damp issues there are some DIY solutions that can help you get rid of damp stains and patches in your house. We have dedicated pages explaining simple measures you can take to reduce condensation and how to tackle penetrating damp by fixing the source of water ingress into the home.

Unfortunately, rising damp or more severe cases of damp are not so easily resolved and you will likely require the expertise of a qualified surveyor to accurately identify and diagnose the problem. If required then they will also be able to install a remedial damp proof course or other professional damp proofing treatment to resolve your damp problems.
