Restumping Cost: How Much Is It, What Affects the Price, Cost Per Stump [2024]

In this article, we’ll discuss the cost of restumping, what affects the price of restumping a house, the cost per stump for restumping, as well as how many stumps are required to restump a house. 

How Much Does Restumping Cost?

The cost of restumping is between $4,000 to $20,000. This cost will depend on various factors, such as the type of stumps used, the number of stumps needed, the nature of the property, and the duration of the project.

What Affects the Price of Restumping?

The price of restumping is affected by the type of stumps used, the number of stumps needed, the nature of the property, and the duration of the project are factors that affect the price of restumping. These variables are always taken into account when restumping in Melbourne.

Let’s take a closer look at each one below.

Type of Stumps Used

The type of stumps used is one of the biggest factors affecting the restumping cost. Concrete, steel, and timber are the most common types of stumps used. Each of these types comes with different pros and cons and price points.

Concrete and steel are known for durability and longevity but can be quite pricey. On the other hand, timber is often more affordable but less durable.

Number of Stumps Needed

The second most important factor affecting the cost of restumping is the total number of stumps required for the project. Bigger properties or those that need extensive support will require more stumps, thus increasing overall expense.

This is especially true since the total cost is calculated per stump, and a higher count translates to greater cost.

Nature of the Property

The nature of one’s property is another factor that affects restumping costs. Areas that have complex structures, such as those with irregular foundations, can expect increased expenses.

Tight spaces and sloping land can also add up to the cost. These accessibility issues contribute to higher expenses when you finally decide to restump your home.

Duration of the Project

Lastly, the duration of the project influences the cost of restumping. You can expect a higher total expense the longer a project takes to complete.

Delays caused by unforeseen complications like structural issues can extend the duration and, thus, increase the cost of a restumping job.

How Much Does Each Stump Cost To Install?

The cost for each stump ranges from $160 to $180 per concrete stump. This price can fluctuate based on factors such as the size and quality of the stump and the supplier. Concrete stumps are a popular choice due to their durability and resistance to decay and pests, which is an issue with timber.

The installation complexity and accessibility of the site can also influence the overall cost per stump. Higher-grade concrete or specialised stumps designed for unique soil conditions or load requirements may also incur additional expenses.

How Many Stumps Will I Need for Restumping?

The best way to determine how many stumps you will need for restumping is to know the total area that needs it. This is usually measured in square metres (m²).

Once you have this number, use the following method:

Area to Be Restumped (in m²) / 1.15

Here’s an easy example to help you understand:

If you have three rooms that need restumping, and each room is 15m². To find out the total number of stumps needed, you would calculate it like this:

Total Area of Rooms:

3 rooms x 15m² per room = 45m²

Number of Stumps Required:

45m² / 1.15 = 39.13 stumps

Since you can’t have a fraction of a stump, we round this number up to the nearest whole number. So, in this example, you would need 40 stumps.

Please Note: This calculation is based on a specific type of footing (footing type 3) and follows the guidelines of AS 1684.4—2006, which is a standard for residential timber-framed construction. 

Each house will have different requirements, so you should always consult a professional to get the most accurate estimate for your situation.
