The cost of house restumping typically falls between $5,000 and $20,000, or around $500-$700 per stump. However, there’s more to consider than just the cost per stump when budgeting for a restumping project.

Homeownership involves a variety of essential maintenance tasks, and restumping is one of those crucial yet often overlooked jobs. Over time, the stumps that support a house can degrade due to factors like soil movement, moisture, termite damage, or simply age. Restumping involves replacing these deteriorated stumps with new ones made of metal, concrete, or timber.

Ensuring that your home is properly restumped is vital for maintaining its safety and stability. If the thought of restumping—and the expenses that come with it—overwhelms you, don’t worry. We’re here to break down the importance of restumping, how to identify when it’s necessary, the costs associated with it in Australia, and more.

What is Restumping, and Why is It Necessary?

Restumping, also known as reblocking, is the process of replacing the foundational stumps under a house. These stumps, whether timber or concrete, can rot, crack, or sink due to various factors, including soil movement. If left unaddressed, such issues can compromise the structure and safety of your home.

The Restumping Process

Though the exact steps may vary slightly depending on the contractor, the general process of restumping involves the following:

• Inspection: The contractor conducts a thorough assessment of the existing stumps and the level of the house’s floors, checking for damaged stumps and any unevenness. They will also evaluate soil conditions and stump depth.
• Raising and Removal: Using specialized equipment, the contractor will lift the house and remove the old stumps. In some cases, additional excavation may be required.
• Installing New Stumps: New stumps are carefully positioned and adjusted to ensure optimal load-bearing capacity and stability for the house.

How to Identify If Your Home Needs Restumping

While you may not be able to see the stumps under your house, several indicators can signal that it’s time for restumping:

• Sloping or Uneven Floors: If your floors seem uneven, it may point to foundation issues that could require restumping.
• Cracks in Walls or Ceilings: Foundation movement can lead to cracks, suggesting a need for restumping.
• Sticking Doors and Windows: Doors and windows that are difficult to open or close might indicate shifting foundations.
• Bouncy or Sagging Floors: If your floors feel springy or sag when walked on, this could mean the stumps are weakened or damaged.
• Visible Deterioration of Stumps: Keep an eye out for any signs of rot, termite damage, or cracks in concrete stumps.

Cost Guide for House Restumping

Now, let’s address the big question: how much does restumping cost? On average, homeowners in Australia spend between $5,000 and $20,000 on restumping, depending on various factors. The price per stump typically ranges from $500 to $700. However, many aspects contribute to the total cost, and it’s important to consider these elements in your budget.

Factors That Influence Restumping Costs

Several factors can affect the final price of a restumping project:

• Professional Fees: These could include site inspections, engineering assessments, or soil tests.
• Condition of Existing Foundations: If the current foundations are still in good shape, it can help lower costs.
• Reusability of Stump Holes: If the original stump holes can be reused, you can save money on excavation.
• Stump Materials: The choice of materials—whether timber, concrete, or galvanized steel—will impact the price. Steel stumps, while more expensive, offer greater durability and require less maintenance.
• Additional Repairs: Sometimes, restumping may uncover other necessary repairs, such as flooring, walls, or plumbing that have been impacted by foundation movement.
• Soil Condition: The stability of the soil beneath your home can affect the cost, as poor soil may require additional work.
• Permit Fees: Depending on your location, you might need to pay for council permits.
• Number of Stumps: The more stumps that need replacing, the higher the overall cost.
• Accessibility: If the space beneath your home is hard to access, labor costs may increase.
• Location: Costs can vary depending on where your home is located, with prices differing between regions and cities.
• Temporary Accommodation: In some cases, you may need to find alternative housing while the work is being completed.

Additional Costs to Keep in Mind

Restumping is rarely a straightforward project. During the process, contractors might discover other issues requiring attention. This could include damage to the house’s structure that only becomes visible once the stumps are replaced. It’s important to budget for these potential additional expenses.

Choosing the Right Restumping Contractor

Given the complexity of restumping, selecting a reliable contractor is essential. Request multiple quotes, check customer reviews, and ensure the contractor has experience and insurance. While price is important, remember that the cheapest option may not always be the best. When it comes to a project as crucial as your home’s foundation, quality should be the top priority .
