How Much Does Waterproofing Cost in Singapore (2025 Guide)

While living in a city like Singapore, where everything is quite expensive, it’s important to learn about how much various services cost. Whether you have a business or a house, waterproofing is an essential service that you are going to require; however, finding the right waterproofing contractor is a difficult task.  If you’re considering waterproofing solutions in Singapore, it’s important to understand the various factors influencing the cost. This guide provides an overview of waterproofing costs in Singapore and how to choose the right waterproofing contractors.

Understanding the Importance of Waterproofing in Singapore

Singapore experiences heavy rainfalls, and humidity is quite common, which makes waterproofing essential. Waterproofing materials help produce a protective barrier that prevents water from leaking into the walls, floors, and other parts of your building. This protects your building against mould and mildew. This also helps prevent leaks and seepage.

Additionally, waterproofing can increase property value by ensuring long-term durability. Without proper waterproofing, property owners may experience costly repairs from time to time. Therefore, investing in quality waterproofing services in Singapore is a wise decision for homeowners and businesses alike.

Factors Affecting the Cost of Waterproofing in Singapore

The cost of waterproofing in Singapore is influenced by various factors, and understanding them can help you make informed decisions and save money. 

Area

Different areas of a property require specific waterproofing solutions, and depending upon the area, the price may vary. Common waterproofing services include roof waterproofing, which safeguards the roof from heavy rains and UV exposure; wall waterproofing, which prevents water from seeping into walls and causing damage; and bathroom and kitchen waterproofing, which is essential for keeping wet areas leak-proof. 

Size of the Area

The size of the space that needs to be waterproofed directly correlates with its cost. More materials and personnel are needed in larger spaces, which raises the overall cost. It will be far less expensive to waterproof a little bathroom than to waterproof the full building area.

Type of Waterproofing Material Used

The cost of waterproofing is largely determined by the material selection. The most widely used waterproofing materials in Singapore are:

• Bituminous coating: Perfect for roofs and subterranean structures. 
• Liquid membrane waterproofing: Offers flexibility and durability
• Cementitious waterproofing: Economical and efficient for bathrooms and kitchens.
• Polyurethane waterproofing: Offers excellent protection from water intrusion.

Labor Costs

The experience and reputation of waterproofing contractors in Singapore also affect pricing. If a company is offering more skilled professionals, it may charge higher fees. Also, if multiple people are required, then the cost may also go up.  However, make sure to choose someone with good experience because their expertise ensures long-lasting waterproofing solutions.

Extent of Existing Damage

In some locations, there is pre-existing water damage, and these properties will have to pay more for repair before waterproofing can be started. Otherwise, the waterproofing won’t work. The total cost will increase due to these extra repair expenses. Make sure to have any water damage repaired as soon as you see it if you want to save money.

Types of Waterproofing Methods in Singapore

Here is a list of a few waterproofing methods used in Singapore: 

Thermoplastic

Using thermoplastic for waterproofing is quite beneficial because it can last up to 50 years. For this method, you will require a flexible plastic material that is durable and resistant to chemicals. It is commonly used in green roofs and chemical facilities. 

Liquid Applied Membrane

Liquid waterproofing membrane is a popular waterproofing technique used in Singapore. This method involves applying a liquid coating to the surface. It forms a flexible, seamless layer which is durable and waterproof. This liquid membrane can expand and contract according to weather which reduces the risk of cracks. It is commonly used for roofs, balconies, and external walls. 

Cementitious Waterproofing

This is a cement-based coating which is rigid and durable against any sort of water damage. People usually prefer this because it is cheaper and resistant to different environmental factors. This reliable waterproofing method is used for wet areas such as bathrooms, kitchens, and basements.

Bituminous Waterproofing

In this type of waterproofing, an asphalt-based material is used for waterproofing. Bituminous membranes provide excellent waterproofing for roofs, basements, and underground structures. They are durable and resistant to extreme weather conditions.

Polyurethane Waterproofing

This high-performance waterproofing method is ideal for areas exposed to high moisture levels, offering superior resistance to water penetration. Ideally it is used in balconies, terraces, swimming pools, and water tanks.

Nano Waterproofing

Nano waterproofing is a new method which uses hydrophobic coating to seal floors, walls, and roofs. These coatings are applied to surfaces to keep vapor transfer intact and stop water intrusion. 

How to Choose the Right Waterproofing Contractors in Singapore

If your home needs waterproofing, find a professional that specializes in this procedure because choosing a reliable waterproofing contractor is crucial for long-term protection against water damage. Start by checking for certificates to make sure the contractor is capable of handling waterproofing methods that are suited to Singapore’s climate. Important information regarding the contractor’s dependability, expertise, and caliber of service may also be found by looking at client reviews. Positive recommendations from previous clients are a strong indicator of a trustworthy contractor.

Furthermore, it is quite important to compare different contractors so you can find out the exact waterproofing cost in Singapore. However, keep in mind that least expensive solution might not necessarily yield the best outcomes, even when cost is crucial. Finally, always inquire about the contractor’s warranty. A trustworthy waterproofing business should offer a warranty, ensuring the longevity and efficacy of their work and providing you with years of worry-free living.

Signs That Your Property Needs Waterproofing

If you see the following issues in your house, it might be time to look into Singapore waterproofing solutions:

Water Stains

Early warning signs of moisture getting into your home include peeling paint, loose wallpaper, and water stains on walls or ceilings. These problems may weaken the walls/roof over time and degrade the overall look of your house or organisation.

Mould and mildew growth

Mould and mildew growth, along with damp or musty smells, are other important indicators of excessive moisture in the house. It not only damages your house but creates an unhealthy indoor environment, which will have negative impacts on your overall health. 

Visible leaks or seepage

If you spot any visible leaks or seepage, then that’s a more serious sign that immediate waterproofing is needed. If the foundation, walls, and other important structures have been damaged by water intrusion, expensive repairs may be necessary. 

Efflorescence

Another visible sign of water damage is a white powdery residue on walls or floors. This suggests water is evaporating and leaving behind salt deposits, signalling ongoing moisture issues.

Cracks in Walls

If the water damage is extreme, then cracks in walls, ceilings, or flooring may appear, weakening your property. Ignoring these warning indicators may lead to long-term structural damage, a decrease in the value of your property, and even health risks from mould exposure. Getting the right waterproofing services in Singapore can help avoid these issues and extend the functionality of your house.
