What’s Rising Damp?

Rising damp is a phenomenon where water from the ground infiltrates buildings through tiny pores in brickwork, known as capillary action. This process can be obstructed by gravity and evaporation, resulting in a visible “tide-mark” approximately one metre high. However, non-porous renders or wall paint may cause other symptoms of rising damp to appear above this level. Porous materials such as plaster, lumber and wallpaper are commonly used for walls and are susceptible to decay and disintegration due to moisture damage. Groundwater salts also rise up through bricks leaving white stains on internal walls which is another common symptom of rising moisture.

Difference Between Rising Damp And Other Types Of Damp

To avoid confusion, it is crucial to consult a damp specialist to correctly identify the type of damp present in your building. A common misconception is that a tide mark on your wall indicates rising damp, but this may not be the case as external factors such as poor guttering, or overgrown vegetation can cause penetrating damp instead. It’s also worth noting that an efficient damp proof course may not have been installed in your property within the last two decades. If you notice mould on your walls, it could signify humidity caused by condensation rather than rising damp. It’s important to understand that, unlike other types of dampness, rising damp cannot exist above ground level since moisture rises from the soil onto the walls of buildings. Consulting with a professional will help determine if you are dealing with rising or another form of damp and how best to address it for optimal results.

Rising Damp Symptoms

There exist a plethora of discernible indicators that your abode is afflicted with the scourge of rising damp, which can be identified by homeowners. Acquiring knowledge on how to detect this malady could aid in promptly rectifying the issue at hand.

Walls With Damp Stains And Tidemarks

Tide marks on walls are a common indication of moisture buildup. These marks result from the evaporation of water and salt migration from the ground, which seeps up through the wall. Typically, tide markings can be observed at the base of the wall to about one metre above it. However, if these markings are not visible, damp patches or stains may also indicate rising dampness. These patches usually appear as dark yellow or brown spots and can be found at similar heights as tide marks. If dampness is presently higher than one metre up the wall, it could still be due to rising damp but might suggest a penetrating damp issue instead. It is essential to exercise caution when diagnosing this type of problem since both types of moisture issues may coexist in some cases.

Appearance Of Damp Or Wet Patches On Walls

Rising damp is a common cause of moist or damp patches on walls, particularly if they are located on the lower section of the wall and your property is situated on the ground floor. Capillary action causes moisture from the ground to rise through brick or stonework, resulting in rising damp if there is no effective Damp Proof Course at the base of your property’s walls. This issue only affects properties’ ground floors since it originates from below. If you experience a damp problem above this level, it may be due to penetrating damp or condensation rather than rising damp. It’s critical to identify and address any type of moisture issue promptly since prolonged exposure can result in structural damage and health issues for occupants.

Smell Is Damp And Musty

The pungent aroma of dampness is a telltale sign that your property may be suffering from this affliction. Even if you cannot see any visible signs of moisture, the musty and unpleasant scent can almost always be detected. However, identifying the specific type of damp causing damage to your property can prove challenging without visible evidence on the fabric of your home. In such cases, it is advisable to seek assistance from a Specialist Damp Surveyor who can diagnose the issue accurately for appropriate treatment. Different types of damp require different treatments; therefore, correct identification is crucial in resolving the problem as quickly as possible.

Dark Mould

The presence of black mould in the lower regions of your wall is a clear indication that there is an abundance of moisture. The existence of this unsightly fungus suggests that you have a condensation problem. However, if the issue arises on the bottom half of your ground floor walls, it could indicate rising or penetrating dampness, which requires immediate attention. It’s imperative to address any form of dampness as soon as possible since it can lead to structural damage and pose health risks for occupants. Therefore, it’s crucial to identify the root cause and take appropriate measures to eliminate excess moisture from your home promptly.

Salts In The Plaster

Through capillary action, moisture rises from the ground and travels upwards through the stonework. As it does so, it collects hygroscopic salts from the earth that migrate into your property and cause damage to plaster and decoration. These salts have a tendency to draw in moisture from the air, resulting in damp walls that may feel wet when touched. When evaporation moisture brings these salts to the surface, they can leave behind a white coating on your wall.

If you suspect rising damp is causing your wall’s dampness, then you must also consider how hygroscopic salts are contributing to this problem. Addressing both issues simultaneously will be necessary for the effective remediation of rising damp-related problems.

Wallpaper Or Paint Peeling

Peeling wallpaper or paint can be a telltale sign of rising humidity levels within your walls. The accumulation of moisture due to ongoing damp issues can cause the wallpaper or paint to detach from the wall surface. This is particularly noticeable in areas such as skirting boards and lower portions of walls, where the wallpaper often peels away first, with edges curling outward. However, it’s important to note that this could also indicate a condensation or penetrating damp issue in your home, requiring an accurate diagnosis for proper repair specification implementation. To ensure effective resolution, it’s essential to identify the root cause accurately before proceeding with any repairs.

Plaster That Is Flaky Or Bubbling

The presence of flaking or bubbling plaster, crumbling plaster, or powdery deposits on the walls of your ground floor is a clear indication that you are dealing with a damp problem. This type of issue could be caused by rising damp, which occurs when moisture from the air rises and causes damage to the plaster on your walls. If left unaddressed, this can lead to significant cosmetic damage to your property’s ornate and decorated walls. The cost of repairing such damages can be substantial for property owners if not dealt with promptly. Therefore, it is crucial to take action as soon as possible if you notice any signs of rising damp in your home.

Skirting Boards And Flooring Rotting

If left unaddressed, rising damp can lead to severe damage in your home’s skirting boards and floors. The excessive moisture caused by the dampness can harm the timbers, making them vulnerable to fungal attacks. This type of decay is similar to other forms of damp that cause rot in direct contact with the timber. Property owners should avoid skirtings and other timbers that show signs of cracking or disintegration upon touch. Visible fungus growth on the skirting boards or flooring timbers may indicate long-term wetness damage to the house. It is crucial for homeowners to address rising damp promptly before it causes irreversible harm to their property’s structural integrity.

Fasteners Made Of Iron And Steel That Have Rusted

Iron and steel that are not protected can succumb to rust when exposed to excessive moisture levels over a prolonged period. Rust can cause fasteners made of iron or steel, such as cavity wall ties, to lose their stability, thereby compromising the structural integrity of the property. The impact of rusted and non-functional fasteners on the property’s overall security cannot be overstated. It is essential to ensure that all metal components in a building are adequately protected against moisture damage to prevent significant harm from occurring.

Bricks And Mortar Crumbling Between Bricks

Ground-floor walls, both internal and external, are susceptible to severe damage from rising damp. Repairing crumbling bricks and mortar can be a costly affair. Rising damp causes the bricks or mortar to become porous, leading to penetrating damp that further damages internal walls. Fortunately, fretting is an easily identifiable condition caused by decaying bricks or mortar.

When inspecting your brickwork or stonework, check for cracking or powdery mortar and deterioration of the brick surface as these are signs of moisture and salt deposits causing fretting. In the later stages of this condition, the joints may have almost entirely lost their mortar content. Therefore it is essential to keep a close eye on cement joints in external brickwork or stonework so that any issues with fretting can be identified early on before they cause significant damage requiring expensive repairs.

Treatment Approach To Rising Damp

Our team of experienced damp surveyors conduct a thorough examination of the affected area before commencing any rising damp treatment. This allows for an accurate diagnosis and identification of the type of damp issue your property is experiencing, followed by necessary repairs to address the problem. Our expert technicians carry out these repairs in a timely and cost-effective manner, tailored to suit your specific property’s requirements. Depending on the type and condition of your property, various rising damp remedial works may be required such as the removal of wall fabric or repair/installation of a new DPC system. In case the old system fails, our experts will instal a brand new chemical DPC that creates a continuous waterproof layer serving as a barrier against moisture from the ground rising up masonry walls.
