Rising damp is a common problem in buildings worldwide. In general, it affects damaged, older buildings and can be identified as wet or damp patches, moss growth, and staining on the brickwork of external walls. If left unaddressed, it may affect lung health and damage your home.

This problem has been around for centuries. Evidence suggests that even the Ancient Greeks and Romans were aware of it. Since damp promotes mold growth, it poses serious health risks.

But what is rising damp in the first place and what can you do about it? Let’s find out!

What Causes Rising Damp?

This type of dump is characterized by ground moisture that rises up a stone, mortar, or brick wall. Water leaks and moisture under the floor, as well as poor sub-floor ventilation, only make things worse. In general, the height of the rise is 0.5 to 1.5 meters above ground level.

Despite its common occurrence, the rising damp is often overlooked or misdiagnosed. That’s why it’s important to contact a professional as soon as you notice any signs of moisture. He can identify its source and recommended the best course of action.

Rising damp can have a variety of cases, from damaged pipes and gutters to sub-floor obstructions. It may be also due to a damaged damp-proof course. Condensation and leaks play a role too.

Warning Signs to Watch Out for

There are a few telltale signs that you may have rising damp in your home. You’ll likely notice clearly defined wet patches, stains, and mold on the walls. Corrosion of bricks and mortar, discoloration on the exterior walls, and tidal marks are common as well.

Depending on its location, rising damp may cause the floorboards and window frames to rot. You may also see rusting steel fasteners, white crystals on the exterior of the walls, and black, white, or green mold growth.

Mold is particularly dangerous to your health. Even if you try to remove it, it will release spores into the air. Inhaling or swallowing these spores can lead to respiratory tract disorders, asthma, wheezing, lethargy, and even pulmonary hemorrhage.

If you notice any signs of a rising damp, reach out to a professional like Findlay-Evans Waterproofing. Companies that provide damp repair and mold removal services have access to the latest equipment and can safely restore your walls.

In the meantime, there are a couple of things you can do yourself to prevent and manage this problem.

What Can You Do About Rising Damp?

Start by identifying the source of moisture. Check your house for leaky pipes, damaged or cracked waste pipes, and sub-floor obstructions. If the damp-proof course is deteriorated, call a professional to repair or replace it.

Take the steps needed to maintain and improve underfloor ventilation. Make sure all surfaces that are in contact with the walls are slightly sloped. Lower the ground level and remove soil if necessary.

Check the external walls to see if there are any items leaning against them, including temporary structures, wood, or debris. Remove them as soon as possible.

Another option is to use liquid injection damp proofing products. These formulas contain silane and other ingredients that help prevent damp. Treatment may also include replastering, land drainage, and installation of porous tubes.

Keep Your Home Healthy

Rising damp is just one of the many issues faced by homeowners. Mold and mildew, falling damp, and penetrating damp are all common problems. The sooner you do something about it, the better.

If you ever decide to sell your home, these problems can negatively impact its sales price and curb appeal. Plus, they represent a health hazard for your family.
