The average cost of underpinning a house in Adelaide ranges from $4,500 to $40,000. Larger projects with more involvement can cost up to $75,000. The price for underpinning depends on a number of factors, including the number of pins being installed, the method used, and access. 

In this article, we’ll go through the common methods of underpinning and what to look for when requesting an underpinning quote.

What Is Underpinning?

Underpinning is the process of reinforcing the foundation of a structure. This is usually done by excavating around the perimeter of the foundation and installing support beams or piers underneath.

What Are the Different Methods of Underpinning?

The following are the most common methods of underpinning:

Concrete Slab Underpinning

Concrete slab underpinning is the most popular method of underpinning in Adelaide. It involves excavating around the perimeter of the house and pouring a concrete footing to support the foundation. This method is quick, relatively inexpensive, and can be done without damaging the house. However, it is not suitable for all types of foundations.

Screwpile Underpinning

Screwpile underpinning is another method of underpinning that has become popular in recent years. It involves driving steel piles into the ground to support the foundation. This method is more expensive than concrete slab underpinning, but it is less likely to damage the house and can be used on all types of foundations.

What Should You Be Looking For In An Underpinning Quote?

These are the following things to look for in an underpinning quote:

Fixed Price Quotation

When receiving an underpinning quotation, be sure it is a fixed-price quote. This implies that the price quoted is permanent and will not fluctuate based on any unforeseen expenditures. Adelaide Underpinning Group always gives fixed price quotes, so you can be certain you’ll know precisely what you’ll pay.

Transparent Quotation

Underpinning quotes should be simple and jargon-free. If they’re not, seek clarification and double-check that you understand everything before going forward. Our team at Adelaide Underpinning Group uses plain English and is always available to answer questions by phone or email.

Fixed Time Frame

When getting an underpinning quote, it is important to ensure that the contractor can provide a work schedule that clearly outlines each stage of the process and how long it will take. They should also be prepared to work according to a fixed timetable, of course, depending on the weather. Adelaide Underpinning Group always provides a clear work schedule and timeline for each job, so you can be confident that the work will be completed on time.

How Risky Is Underpinning?

Underpinning is extremely risky when it is performed by someone who doesn’t fully understand its process. This type of work can be dangerous especially since it could damage a home or even lead to its eventual collapse.

That’s why hiring an expert underpinning contractor is best to ensure the whole process goes smoothly.
