Some of the factors homeowners consider when hiring a waterproofing contractor for their bathrooms/toilets are the rates and availability of the staff. Many homeowners will prefer to hire the cheapest service provider, and do not bother to check the competence of the company. However, even if you are on a budget, it is important to know whether the staff is well trained, whether the company offers any warranty, and the quality of the bathroom/toilet waterproofing works.

There are multiple reasons as to why you should not opt unqualified bathroom hacking waterproofing services. If you still decide to do so, listed below are some of the problems you may encounter.

Reinforcement Corrosion

The building structure has multiple concrete beams with steel rebars for reinforcement to provide support. If the bathroom waterproofing is not done properly, you will experience  water leakage which will spread from the bathroom floor to the building structure. This occurs because concrete is a porous material that absorbs water. When water reaches the steel rods, they will rust and weakens. The beam may even collapse in some cases, especially during cyclones or heavy rain.

Mold Growth


Water leaks will keep occurring in bathrooms that are not waterproofed properly, creating the ideal environment for mold, algae, and mildew to flourish. Mold spores can also cause allergies, and other respiratory and health problems apart from discoloring walls, damaging furniture, documents, and furnishing.

Low Indoor Temperatures


Without adequate bathroom waterproofing, water will continue to leak whenever you use your toilet or bathroom. The leaking water will then evaporate and cool the surfaces, causing the house to have a lower temperature during winter. Hence, homeowners will have to spend more money to keep the rooms warm, by using a heater.

Concrete Spalling

Poor quality bathroom waterproofing and hacking will result in concrete spalling, which makes it difficult to keep the house clean. Concrete is a porous material which absorbs toilet leaks. The concrete will expand when it absorbs water, and the temperature variations will cause some of the concrete to fall off.

This is dangerous for people in the room, since falling concrete pieces can cause injuries. Additionally, the paint will also start to come off from the walls where the concrete is expanding or absorbing water, covering different items kept in the room. If the concrete or paint falls on food kept in the house, it will have to be discarded.

Respiratory Diseases


Another side effect of hiring incompetent waterproofing contractors is that the leaking water creates an ideal environment for algae, mold, viruses, and other harmful microbes. These microbes adversely affect the air quality in the room, increasing the risk of respiratory diseases.

The cement, concrete, and paint will also fall off frequent, which worsens the quality of the air in the room. This will cause coughing and breathing difficulties especially at night and during winter. Medical treatment of such illnesses is expensive, so it is better to hire competent waterproofing specialists.
