Damp Proofing Services
Damp Proofing is the process of treating damp damaged plaster and walls. Rain and moisture, from external cracks, window frames and weep holes penetrate the internal walls and cause damage. The moisture rises up the internal wall by capillary action and evaporates, leaving efflorescence and hygroscopic salts. The contaminated plaster is damaged and must be removed, the underlying brickwork needs to be sealed with a waterproof sealant to prevent rising damp and replastered by using a high-quality Damp Proofing system. If Damp is not treated it can be harmful to the structural integrity of your home or building.
What is Damp and what are the causes of dampness within a building or home?
Moisture can be found in excess in one material and not in another, it all depends upon the structure, porosity and density of the material. Most damp is caused by the ingress of moisture which can be in the air or substrate. Moisture ingress can be caused by water entering through cracked walls, water penetration from irrigation systems, pipes that are leaking, water seepage through window frames and doors or high water tables in the ground. Damp can be identified by sight, smell & damp moisture meter. There are mainly 4 types of Damp.
Rising Damp is usually found in older buildings and results from either the failure of all or part of whatever dampproof course (dpc) was previously fitted or the absence of such a dpc. Signs of rising damp is the presence of damp on internal off-leading walls which include a band or tide mark which is clearly visible. Hygroscopic salt deposits e.g. chlorides or nitrates on the wall, bubbling paint or damaged plaster confirm a problem exists or has existed previously. Aided with an electronic moisture meter, our representative will determine the extent and causes of the damp problem. A complete and proper recommendation/report is only given after a thorough investigation.
Lateral Damp may be described as the horizontal movement of moisture in a substrate. It may or may not lead to Rising Damp depending upon the circumstances. Typically it is a result of differing ground levels, often associated with outside gardens, flower beds raised paving etc and internally due to raised floor levels with backfill beneath.
Condensation commonly occurs when a vapour is cooled to a liquid and is typically found in bathrooms and showers, especially where there is no ventilation in the room. Water vapour will only condense onto another surface when that surface is cooler than the temperature of the water vapour. It is often detected by moisture on glass windows and mould and moisture on walls and ceilings where a musty damp smell is usually present. By improving ventilation and taking simple measures by installing extractor fans in the kitchen and bathroom or opening windows condensation can be reduced. We can survey your home and provide you with a written report/quotation.
A common problem in the Cape in particular and other parts of the country is that of Penetrating Damp. This is typically found in face brick buildings where porous bricks have been used or where the pointing has deteriorated. Penetrating dampness is also usually due to external defects such as blocked or leaking pipes, open mortar joints and cracked porous brickwork or stonework. Damp penetrates the brickwork and then contaminates the inner surfaces of the walls with the same symptoms as mentioned above.
Ways to tell if you have some sort of damp.
- Blistering paint on the wall surface
- Visible wet patches on the walls
- Rotting or damaged skirting boards
- Wallpaper or Paint peeling off the wall
- Visible damp patches on the floor
- Lifting of Floor Coverings

Roof Cleaning & Painting
Before painting commences, repairs such as dampproofing and rust treatment are attended to. The repair process is followed by a cleaning process, where the roof or walls are cleaned with a high pressure cleaner, or steel brushes, to remove loose paint and dirt, depending on the type of surface.
Fascias & Eaves
We offer repairs to any affected fascia boards, eaves and roof structure. Fascia Boards & Eaves are often overlooked when homeowners repaint their roofs. It is important to maintain the facia boards and sustainability of your home. When exposed to severe weather, the wooden fascia’s can quickly rot as it is made of wood.
High Pressure Cleaning
One of the essential requirements for the repair/painting of your roof is a high pressure water cleaning. This will remove dirt, moss, mould, leaves and grime or any other foreign substance that may have build up over the years. High Pressure cleaning will give your roof a fresh clean look and ready for painting.
