Damp problems are a major problem in many residential properties in the Uk and have also been the major cause of poor indoor air quality.
When a residential property is described as “damp,” it means that there is moisture, wetness, and condensation are present.
If you experience this, you need to get your property treated immediately because dampness can make your residential space unpleasant and uncomfortable to stay in.
And not just that, a damp property could be a breeding ground for mould, which can cause various kinds of respiratory ailments.
Hence, in this article, we’ll be discussing damp problems in residential properties and the types of treatment you can use to get rid of these problems.
What are the types Of Damp Problems Found In Residential Properties?
You need to know the type of damp problem affecting your property first, so you can choose the most suitable type of treatment.
There are three major types of damp problems found in a residential property. They are discussed below
- Condensation Damp Problems
This is the most common type of dampness you can find in most residential properties and it occurs as a result of moisture that has condensed on walls.
It happens mostly in rooms that tend to generate moisture. For example, in the bathroom and kitchen. It can be partly caused by winter but not always.
The Central Heating System that usually heats up before cooling off again might make condensation worse because it creates moist air that can eventually condense.
Some of the causes of condensation in residential properties might be a result of daily activities carried out, which include cooking, showering, and drying clothes, and through these activities, moisture is released into the air.
Once there is a lack of ventilation, especially in old homes, the damp problem becomes worse.
How To Identify Condensation Damp Problems in Residential Properties
- Droplets of water on the walls and windows
- The presence of a dark mould is mostly around the window or on the glass
- A foul and mouldy odor.
- The humidity level tends to increase
Consequences of condensation in residential properties
- If the dump condensation is not treated, it can damage the plaster and paint.
- The window frames might decay or rust, so it is advised to tackle the problem as quickly as possible.
- Rising Damp Problems
This usually happens as a result of groundwater seeping through a wall or floor. Although it is normal for floors and walls to let some water through, there is a preventive measure to prevent it from causing any harm.
In cases where there is a lack of a drainage system, it can also lead to rising damp problems. The absence of a damp proof course can also be the cause.
How To Identify Rising Damp Problems in Residential Properties
- The floor covering the property may swell up if the issue is coming from the ground.
- Noticeable risen tide lines are visible on the walls.
- Peeling of wallpaper and paint that frequently has moist patches
- The plaster or skirting board is damaged.
- Iron and steel fasteners rust.
- Staining of wall covering
- Moist and damp in odor
- Penetrating Damp Problems
Penetrating damp tends to move horizontally and expand across the ceiling and walls of your home and is usually caused by water leaking through the walls of the building.
It can also happen as a result of proofing cracking walls, internal leakage, or structural problems such as faulty quarters.
If the walls of your building are solid and old, you will probably experience this problem.
In most cases, if the cavity wall insulation is not installed properly, it can lead to penetrating dampness.
How To Identify Penetrating Damp Problems in Residential Properties
- Exterior wall with damp stains
- Indications of black mold or spots in one area
- Dry patches are located on the ceiling and walls.
- Wet and crumbly plasters
Types Of Treatment For Damp Problems In Residential Properties
There are different ways of treating damp problems in residential properties and they are listed below.
- Damp Proof Course
This is generally known as a treatment for damp and it is applied in commercial or residential properties to prevent damp problems.
A damp-proof course is also known as a horizontal type of waterproof strip that is usually built into the wall at a height of 15 cm above ground level. It is typically made from bitumen felt or plastic.
- Damp-proof Membrane
The damp-proof membrane is known as a sheet of water-resistant type of material that is usually positioned beneath the floor.
It is usually connected to the damp-proof course to ensure that the property is watertight and sealed properly.
- Electro-osmotic Damp Proof
With the electro-osmotic damp-proof course option, the water rising through your wall is resisted and directed back to the ground with an electric charge.
- Chemical Dampness Protection
A damp-proof course that incorporates chemicals may be more useful than one that is solid. To generate a water-repellent layer, the silicone-based liquid is injected into the wall at least 150mm from the base.
- Pressure Grouting
As a practical and affordable alternative to a damp-proof course, gaps and holes in a building’s construction might be filled with grout or concrete.
Before concrete is pumped into the voids to make them moist, holes are bored into specified places in the building that are often selected by a specialist.
- Integrated Damp Proof
During the mining process, components are mixed with the residential building’s metal and concrete to create an inherent damp-resistant course.
This is done to ensure that the concrete is damp-proof by filling any spaces.
- Cavity Damp Proof Wall
A cavity wall’s function is to divide the inner and outer walls. The cavity wall serves as a barrier to stop dampness from transferring from your warm inside walls to the cold outer wall.
Most residential houses are expected to have the damp-proof course and all of the damp-proof membranes as it is now a requirement under the building regulations.
How To Generally Identify Damp Problems In Residential Properties
To look out for damp problems in your residential properties, it is advisable to do the below listed.
