Waterproofing is essential to maintaining any property, especially in a city like Sydney, where the weather can be unpredictable. From torrential downpours to salty sea air, structures are constantly exposed to moisture, making waterproofing a crucial step in any construction or renovation project.
Whether you are considering waterproofing for a new build or as part of an apartment renovation in Sydney, understanding the costs involved is vital for budgeting and planning. This article reveals the factors influencing waterproofing costs in Sydney and provides a detailed overview to help you make informed decisions.
Factors Influencing Waterproofing Costs
To understand the cost better, it is important to know the factors that influence the cost, and these include:
- Type of Waterproofing
The cost of waterproofing in Sydney largely depends on the type of waterproofing system chosen. There are several methods available, each with its cost implications. Common waterproofing methods include:
- Liquid Membranes: Applied in a liquid form and then cured to create a seamless, flexible barrier. Prices typically range from $40 to $60 per square meter.
- Sheet Membranes are pre-formed sheets applied to surfaces. They are usually more expensive, costing between $50 and $70 per square meter.
- Cementitious Waterproofing: This is often used for wet areas like bathrooms and basements. This method is relatively affordable, costing around $30 to $50 per square meter.
- Bituminous Coating: Commonly used for roofs and below-ground structures, with costs ranging from $45 to $65 per square meter.
- Area to be Waterproofed
The size of the area requiring waterproofing is a significant cost determinant. Larger areas naturally require more materials and labour, increasing the overall expense. Waterproofing a small bathroom in an apartment renovation in Sydney might cost a few hundred dollars, whereas a large basement or entire roof could run into the thousands.
- Condition of the Surface
The existing condition of the surface to be waterproofed also impacts costs. Surfaces in good condition require minimal preparation, whereas damaged or uneven surfaces may need extensive preparation, including cleaning, repairing cracks, or levelling. These preparatory steps add to the total cost.
- Labor Costs
Labour costs in Sydney can vary depending on the complexity of the job and the expertise of the professionals hired. On average, labour costs for waterproofing in Sydney range from $50 to $100 per hour. It is advisable to hire licensed and experienced contractors to ensure quality workmanship, even if their rates are higher.
- Accessibility
The ease of access to the area that needs waterproofing can affect costs. Easily accessible areas like open floors or ground-level walls are simpler and cheaper to work on. Conversely, areas that are difficult to reach, such as high roofs or confined spaces, may require specialised equipment and more time, increasing the overall cost.
- Additional Services
Additional services such as mould remediation, drainage installation, or structural repairs will increase the cost. These services are often necessary to ensure the effectiveness of the waterproofing and protect the integrity of the building.
Typical Costs for Waterproofing in Sydney
Based on the abovementioned factors, waterproofing costs in Sydney can vary widely. Here’s a rough estimate for some common scenarios:
- Bathrooms: Waterproofing a standard bathroom typically costs between $500 and $1,000, depending on its size and condition.
- Balconies: The cost of waterproofing a balcony can range from $1,000 to $3,000. The higher cost is due to the exposure to the elements and the need for durable materials.
- Basements: Basement waterproofing costs can range from $3,000 to $10,000 or more, depending on the size and complexity of the job.
- Roofs: Waterproofing a roof can cost between $4,000 and $15,000, depending on its size and the type of waterproofing system used.
