How Much Does Waterproofing Cost in Singapore?

Waterproofing Contractor in Singapore (FAQ's)

Why is waterproofing important in Singapore?

Singapore is a country with a high-humidity, heavy rainfall, and tropical climate, which is mainly responsible for water damage, mold growth, structural deterioration, and building damage. Therefore, if you want to protect your building from water damage and ensure long-term protection, waterproofing is important.

Generally, we provide a warranty of 1 to 10 years. At the same time, the warranty of waterproofing service depends on the areas of leakage and the materials we used. Contact us to know the exact number of warranties.

Singapore has frequent rainfall and a tropical climate. In Singapore, waterproofing is used in industrial, commercial, and residential buildings, especially on roofs, bathrooms, walls, basements, ceilings, swimming areas, and other leakage areas.

The cost of waterproofing depends on several factors, such as the quality of waterproofing materials, surface area, complexity of the affected areas, and labor cost. To get the exact price, contact CWP for a free on-site inspection.
