How long does it take to restump a house?

The total time to complete restumping a house mainly depends on how many stumps need to change and the size of your home. On average, restumping a house will take between 3 to 7 days. However, other conditions can come into play.

In this article, we will explore the different variables that could affect the time to restump a property. After the discussion, you will know what to expect before beginning your renovations.

How long does restumping take? 

Between 3 and 7 days is the average time that requires restumping or reblocking a house. Though the time can go up and down for several variables –

  • The size of the house. The bigger the size, the longest the completion date will be.
  • Quantity of stumps that need to change
  • Access below the floor
  • The job’s complexity

What is the process of restumping a house? 

Most restumping projects will follow a similar schedule. The process of restumping is as follows:

Remove Damaged Stumps

The first thing is to raise the house by jacking it up so that the subfloor doesn’t collapse during the restoration process. Then we dig around the stumps that need to be replaced. To do this, we dig up the ground around the stumps and remove all waste.

Replace New Stumps

After clearing the debris, the new stumps are placed into the hole where the old stumps were or beside. The new concrete stumps (often steel) now need to be concreted roughly 600mminto the ground.

Backfilling Around Stumps

Finally, once the concrete has been set, the area around the new stumps is backfilled and the area cleaned.

Will reblocking cause damage to my home? 

No, reblocking or restumping is a safe and controlled process, and there will be no harm to your home. The only time restumping may damage your house is if you haven’t renovated with floors that are out of level and they need to be lifted. This can cause problems but will be discussed with your chosen reblocking contractor.

How often do you need to Restump? 

If the contractor follows proper procedure, restumps will perform well for decades. However, it can vary on –

Timber Stumps – Average lifespan is 20-30 years.

Concrete Stumps – Can serve well for 50 years

Steel Stumps – Steel stumps have the highest lifespan if not damaged by rust.

Check your stumps every few years by licensed professionals or structural engineers, so that you know how your stumps are performing. It’s not a task that you can try at home or DIY. If you plan to DIY your house, please read this blog can you restump a house yourself to know whether it’s safe or not for you and your house?

Do I need to restump the whole house? 

If all or most of your stumps are damaged, you will need to restump your whole house. On the other hand, if only a few stumps are damaged, then you don’t need to restump your full house. 

Although it may be tempting to wing it, you should always consult a professional who can help you make the best decision.

Can I do relevelling instead of restumping? 

Releveling is a process that can only be possible when the building is on concrete stumps or steel stumps and performing well. The stumps should not be cracked or damaged and the gap between the top of the stumps and bearers should not be over 25mm.

If the terms mentioned above don’t meet, you can’t relevel, so you must restump your house. However, if all the conditions are met, you can relevel using a local professional contractor.

Restumping a house is a process of replacing the stumps that hold up your home. Depending on size and complexity, this process can take 3 to 7 days. Always consult a skilled, professional, and experienced contractor to finish the work on time and with quality.
