RISING DAMP SYDNEY, WHAT CAUSES IT, SIGNS AND WHAT CAN BE DONE TO TREAT IT?

Rising Damp Sydney – Damp is the occurrence of moisture within the structure of a building property. Although Sydney experiences a mean annual rainfall each year, damp is one of the most common issues encountered in many Sydney homes. This problem is caused by rainwater and inadequate drainage. It can also occur from a lack of proper maintenance regarding the windows, walls, and floors as well as defects in pipework, poor pointing, cracked rendering and faulty flashings. But the most common form of damp in many homes in this country is condensation.

Damp is usually identified by the “musty” smell, patches or mould that appear within the bricks and mortar of a home. Its effects include structural failure, risks of mould occurrence, degradation of the interiors of a property and even more deadly, aggravated respiratory issues.

Accordingly, Rising Damp arises from water soaked up from the ground or floor through capillary action and is a common problem in buildings with a damaged damp proof course (DPC) or those with no damp proof course at all. Rising damp usually occurs above 1m above ground level when the adhesion of water to the floor or wall is stronger than the cohesive forces between the water molecules.

How to identify the Signs of Rising Damp Problem

As rising damp can quite be a big problem, it’s best you be on the lookout that the issue is not affecting your building property. When attempting to identify signs of rising damp, make sure you look out for:

  • discolored skirting boards and floors,
  • Paint and wallpaper peeling away from the walls
  • Peeling walls and stained or crumbling plaster.
  • Decayed timber floors

If you notice any form of damp is present in your home, the best idea is to call up an expert to carry out a specialist inspection.

At Mould Removals Sydney, we suggest to our clients the most effective way of understanding rising damp problems by inspecting the structure and the areas with rising damp issues, then use modern technological detection devices to holistically depict the problem.

How to Treat Rising Damp Sydney

The processes for the treatment of rising damp include but not limited to the following: preventing condensation in the property through sub-floor ventilation systems; the use of air purification systems and damp proofing.

Minimizing Condensation

Condensation is the major cause of rising damp that you can partially manage. Condensation is mainly caused by poor ventilation and heating. It occurs when indoor activities such as cooking and bathing increases the level of humidity in a building. That is, the air in the kitchen and bathroom condenses on cold surfaces – walls and windows. Running water through windows is the most common signal of condensation and this can lead to mould on paint and wallpaper, decaying windows frames and stained curtains. Here are some tips for minimizing condensation:

  1. Ensure less moisture on your property: There will always be moisture on your property but adding to the amount will only increase the presence of damp. Dry your clothes outside often, rather than on the radiator. Also, make sure you have your windows open when showering or bathing and use the ventilator when cooking.
  2. Ventilate and sub-ventilate your property: Leaving your windows slightly ajar can really help in reducing the natural moisture that occurs from the environment and weather. Close the kitchen and bathroom doors when you’re using these rooms and open their windows accordingly. Adequate sub-floor ventilation is important for all properties having continuous rising damp problems. Also, keeping space between your furniture and the walls allows air to widely circulate. Investing in air purification systems is another great way to tackle rising damp and remove moisture from your property.
  3. Heat, draught proof and insulate your property: The warmer your property is, the less likely the presence of moisture, damp and condensation. Ensure you keep your property heated as much as possible and install draught-proofing and insulation systems for the walls, lofts, and windows to prevent heat loss and keep your building warmer for a longer period. The installation of double-glazed windows on your property is another effective option.

Invest in Air Purifications and Dehumidification Systems

One common solution to the issues of rising damp is the use of air purification systems. The air purification systems come in various sizes and shapes from smaller-sized units that can keep your wardrobe and closet clean and dry to larger units which can clear out anything from walls, floors to a whole house.

Having an air purification system in your home is a worthy investment. It also helps diminish the air pollutants in your environment which eventually makes the air you breathe clean. With air purification systems, your home will be free from air pollutants and contaminants as well as unwanted lung diseases. Also, these purification systems can help diminish unpleasant odors.

The air outside your home is not always healthy for respiration and even the air inside your home is also polluted. There are several ways through which contaminants are added to the air which makes the air harmful. For instance, car exhaust, smoking, pet urine, moulds, bin areas, bacterial and virus particulates, pollen, etc.

Accordingly, dust particles, pet hair, and other contaminants settle on furniture and clothes, which can adversely affect the skin and cause serious health problems. Air purification systems are indeed a worthy investment and advisable to get in order to handle the air pollution problems presently facing Sydney.

These devices purify air through filtrations and they come with many other features. Installing them in your homes will provide you with massive health benefits, as they supply clean air free from the many harmful particles that are likely to increase the risk of lung illnesses for a whole lot of people. The filtration system of these machines processes the indoor air countless times. Ultimately, the air purification machines purify the air in a room up to 97% and then free the inhabitants from the unsafe air pollutants and contaminants.

Again, any type of poor plumbing seals or gaskets can have a small leak and this can introduce sewer odor. An air purification system is considered as helpful equipment for odor removal. It will also reduce the odor coming from urine absorption in tiles and tile grout – perhaps from kids or pets and eliminate this air contamination problem.

If you would like to be assured that you’re breathing clean air in your home, then, try to install a central air purification system. And the best way to get an efficient installation of air purifiers for the whole house is through the expertise of a professional contractor like Moulds Removals Sydney.

Damp Water Proofing Sydney

If your property has a history of a rising damp problem, it’s better you quickly find ways to alleviate the situation before it gets out of control. Damp proofing is one great solution to rising damp problem but requires a professional expertise. Depending on the type of situation of the rising damp, it could involve one or more of the following measures:

Damp Proof Course (DPC): When it comes to the treatment of rising damp, a quick solution is to damp proof course. The DPC process involves drilling holes into the structure’s internal and external walls and injecting the bricks of the structure with a chemical damp proofing fluid in order to lessen the movement of water through the wall by capillary action. The damp proofing course acts as a barrier to damp rising from the ground and passing into the walls. Choosing this measure will also involve having to re-plaster the walls. DPC comes with varying guarantee periods between 20-30 years. In some cases, the internal patches of the property will have to be rectified by making appropriate repairs, such as re-pointing. However, if this rising damp problem is more widespread in the property internally, this can lead to a higher moisture content in the decorative finishes, plasterwork and/or even the home in general. This will then require a more complex solution – cementitious tanking.

Cementitious tanking: Cementitious tanking is the most effective solution for rising damp problems. This system involves the use of cladding or coating on the floors and walls of a building so as to seal moisture out. To effectively stop the continuous rising damp problem, some form of external weather protection such as a resin-based clear coating, external wall insulation or a rendering system would have to be applied by a mould removal specialist.
