The cost to underpin a house in Melbourne is between $5,000 to $40,000. The total cost is affected by the severity of the damage and how much work needs to be completed. Larger projects which involve a significant amount of underpinning can cost up to $80,000.
In this post, we’ll look at the cost of underpinning a home in Melbourne. We’ll discuss the various underpinning techniques and how they may influence pricing.
What is Underpinning?
Underpinning is a repair process that aims to repair or strengthen the load-bearing capacity of a house’s foundation.
This is usually done when the original foundation is no longer stable or strong enough to support the weight of the house or structure. Underpinning is also used when additional height is added to a building.
The underpinning process strengthens the foundation of a building by increasing its load-bearing capacity. Usually, piers or pins and other means are used to add extra support to the damaged foundation. Underpinning is essential when the existing foundation loses its strength to bear the load of the house or structure.
What are the different underpinning methods?
The two most traditional and commonly used methods for underpinning a house are Concrete Slab Underpinning and Screwpile Underpinning. Both have distinct advantages and disadvantages and are used in different cases.
Concrete Slab Underpinning
Concrete slab underpinning is the most commonly used foundation underpinning in Melbourne. It involves digging deep into the ground and pouring concrete footing to support the foundation. The technique is quick and safe for your home. However, it isn’t suitable for all types of foundations.
Screwpile underpinning
Screwpile underpinning is the process of repairing a building’s foundation using long steel screws driven deep into the ground to support the building. Screwpiles need to go deep into the soil until it reaches a stronger sub ground. Once it reaches the required depth, concrete is poured to secure the perimeter.
What Should You be Looking for in an Underpinning Quote?
Check your underpinning quote that matches any of these methods:
Fixed Price Quote
Always request a fixed-price quote when inquiring about an underpinning job. This means that the company cannot change the quoted price later on. Make sure that all the required tasks are included in the quote.
Transparent quote
Underpinning quotes should be straightforward. The price should be all-inclusive, with no hidden costs or extras. The company should also be able to provide a detailed explanation of the underpinning process and what is included in the quote.
Fixed time / fixed schedule:
Ensure the contractor you hire provides you with a fixed time or work schedule that includes all the required tasks and a detailed outline of each stage with the total amount and time.
