When Your Home Starts to Move, We Help It Stay Put

Practical underpinning for Tasmania’s North West Coast—clear advice, solid results.

If you’re noticing cracks in the walls, doors sticking, or floors starting to slope, you’re not imagining it—your home may be on the move. It happens more often than you’d think on Tasmania’s North West Coast. Weather, soil conditions, and age all play a part. That’s where Underpinning Ulverstone from Mirage Building comes in. We help homeowners stabilise, strengthen, and future-proof their properties with practical solutions that make sense for local conditions.

In this guide, we’ll walk you through what underpinning is, the signs your home might need it, the benefits, and how the Mirage Building team handles everything from first inspection to final handover. No jargon, no fluff—just clear information so you can make a confident call about your home.

 

What is Underpinning (and how is it different from restumping)?

Underpinning is the process of strengthening and stabilising your home’s foundations when they’ve moved, settled, or weakened. In practice, that can involve adding new footings, extending existing foundations deeper, or supporting the structure with engineered systems so the building rests on strong, stable ground again.

Restumping (also known as reblocking) is similar in spirit but different in method. Instead of dealing with a continuous concrete footing, restumping focuses on replacing or upgrading the stumps that support timber floors. Many older homes around Ulverstone and along the Forth, Leven, and coastal corridors sit on timber or concrete stumps that can deteriorate over time. When stumps fail, floors become bouncy or uneven, and doors go out of square.

At Mirage Building, we do both—underpinning for footing-related movement and restumping for subfloor support issues. In many homes, they go hand-in-hand.

 

Why homes in Ulverstone move

Ulverstone’s mix of coastal breezes, seasonal rainfall, patchy drainage, and varied soils (including reactive clays in some pockets) can all contribute to foundation movement. Add in mature trees, stormwater that’s not quite doing its job, or renovations that changed how loads transfer through the structure—and you’ve got a recipe for settlement over time. It’s common, fixable, and best handled early.

 

Clear signs your home may need underpinning

You don’t need a measuring tape to spot early warning signs. Keep an eye out for:

• Diagonal cracks in internal plaster or external brickwork, especially around windows and doorways.

• Gaps are opening up between skirting boards and floors or between benchtops and splashbacks.

• Doors and windows are sticking, catching, or not latching properly.

• Uneven or sloping floors that make furniture sit awkwardly or roll.

• New cracks appear after weather changes, like following heavy rain or a dry spell.

• Movement in verandahs or additions that don’t seem to “sit right” with the original house.

If any of these sound familiar, it’s worth getting a professional assessment. Small, early fixes can prevent larger, more involved repairs later.

 

The benefits of Underpinning in Ulverstone

When done properly, underpinning delivers peace of mind and a tangible improvement in how your home looks, feels, and functions.

1) Structural stability
Underpinning restores support where it matters most—beneath your walls and load-bearing points. That means fewer new cracks and a home that feels solid underfoot.

2) Protects your investment
A stable home retains its value. Underpinning addresses the cause of movement, not just the symptoms, which can be reassuring for future valuations or sales.

3) Smoother doors, windows, and finishes
Real-world wins: doors swing freely again, windows open without a fight, and patch-repaired cracks stay neat because the underlying movement has been managed.

4) Confidence to renovate
If you’re planning a new kitchen, bathroom, or extension, underpinning ensures the base is right—so you’re not building over a problem.

5) Tailored solutions
No two homes are the same. Mirage Building recommends underpinning methods that suit your house, location, and soil conditions, rather than a one-size-fits-all fix.

 

Our Ulverstone underpinning process (step-by-step)

We keep the process straightforward and transparent so you always know what’s happening and why.

1) Initial chat & site visit
We start with a conversation about what you’re seeing at home—when cracks appear, where doors stick, and what’s changed recently. During the site visit, we examine the structure, subfloor (if accessible), drainage, and signs of soil movement.

2) Assessment & recommendations
You’ll receive a clear, plain-English explanation of what’s going on and the options to address it. If engineering input is needed (common for major works), we coordinate that for you.

3) Planning & access
We agree on the scope, timeframes, and access points. We also discuss how we’ll protect gardens, paths, and interiors during the works.

4) Underpinning works
Depending on your home, this may include hand-excavated pits beside the existing footing, staged pours to extend foundations deeper, subfloor repairs (if needed), and stabilisation at specific load points. If restumping is also required, we schedule it seamlessly.

5) Finishing touches
We tidy the site, remove waste, and complete any agreed cosmetic patching to affected areas so the home looks cared-for and complete.

6) Helpful aftercare tips
We share simple maintenance advice around drainage, watering gardens near the home, and seasonal checks so your foundations stay happy.

 

Underpinning methods we use

Different homes need different approaches. Here are the common methods we use across Underpinning Ulverstone projects:

• Mass concrete underpinning
  The traditional, proven approach. We create sequential pits under selected sections of the footing and pour concrete to extend the foundation to a deeper, more stable stratum. Done in stages to maintain support at all times.

• Beam and base systems
  Where loads are concentrated or the ground varies, we may form reinforced concrete beams tied to bases at key points. This shares the load more evenly and reduces the likelihood of further movement.

• Targeted underpinning at high-load points
  Chimney breasts, archways, verandah posts, and addition junctions often need concentrated support. We underpin precisely where the building demands it.

• Restumping/subfloor upgrades
  If your home sits on stumps, we can replace failing timber stumps with concrete or steel options and ensure the bearers and joists are re-levelled correctly. Often paired with underpinning for a complete structural refresh.

• Drainage and moisture management
  Underpinning performs best when water is moving away from the house. We assess downpipes, surface runoff, and subsoil drainage and recommend improvements that protect your new works.

 

What makes Mirage Building a good fit for Ulverstone homes

• Local know-how
  We work across Ulverstone and the North West Coast, so we understand the typical soil profiles, common house types (from cosy weatherboards to brick veneers and mid-century cottages), and the way local weather patterns influence foundations.

• Clear communication
  You shouldn’t have to interpret engineer-speak. We explain what’s happening in everyday language, lay out the options, and help you choose a path that suits your goals.

• Respect for your home
  We plan carefully to minimise disruption. Access points are considered, protective coverings are used where needed, and sites are left tidy.

• End-to-end capability
  From underpinning and restumping to minor rectification of affected finishes, we manage the moving parts so you don’t have to juggle multiple trades.

 

Underpinning vs. Restumping: which do I need?

A quick way to think about it:

• If your walls (brick or timber frame) are cracking and your doors/windows are going out of square, the footings may be moving → underpinning is likely part of the solution.

• If your timber floors feel spongy, bounce in places, or slope, the stumps may be failing → restumping could be the fix.

• Many homes need a combination. We’ll assess both the footings and the subfloor so you get a complete plan.

 

FAQs about Underpinning in Ulverstone

Will the underpinning fix every crack?
Underpinning stabilises the foundations so cracks stop developing or getting worse. Cosmetic cracks are generally patched after movement is controlled. Some hairline marks may remain, but the aim is stability first, then neat finishes.

Do I have to move out?
Usually, no. Most underpinning and restumping can be completed while you stay at home. If we need access to specific rooms or the subfloor, we’ll coordinate with you so day-to-day life keeps humming along.

How long does it take?
It depends on the extent of the work and access. A small, targeted underpin may be relatively quick; a full-scale stabilisation or combined restump takes longer. We’ll map out a realistic schedule once we’ve inspected your property.

Will the house be level afterwards?
The goal is stability, not necessarily dead-level perfection (especially in character homes where a little charm remains!). That said, many areas can be re-levelled significantly as part of the works, particularly with restumping.

What about drainage?
Great question. Managing water is half the battle. We look carefully at gutters, downpipes, surface runoff, and garden beds close to the house. Simple improvements can protect your foundations for years.

Is the underpinning messy?
There’s excavation involved, so yes, some mess is unavoidable. We set up the site thoughtfully, use protective coverings, and clean up thoroughly at the end.

 

Practical tips to protect your foundations

Even a stable home appreciates a bit of care. Here’s what you can do year-round:

• Keep gutters and downpipes clear so water doesn’t overflow near footings.

• Direct stormwater away from the house with sound drains and well-graded paths.

• Water gardens consistently in dry spells, especially near the perimeter, to avoid dramatic soil shrinkage.

• Be mindful of large trees close to foundations; they can influence moisture in reactive soils.

• Check for leaks in garden taps, irrigation lines, or hot water systems—little drips add up.

• Keep an eye on cracks and take photos every few months; if you notice changes, we’ll know exactly what to look at.

A note on heritage and character homes

Ulverstone’s character homes—from cosy weatherboards to Federation-era gems—often have timber floors on stumps and shallow footings. We love working on these properties. Our approach balances respect for original materials with the practical upgrades that make living easier today. If you’re planning a renovation, it’s smart to look under the hood first—underpinning and restumping can save headaches down the track.

 

Why act sooner rather than later

Foundation movement rarely fixes itself. Left unchecked, cracks widen, doors stick more, and cosmetic repairs don’t hold. Early intervention keeps the scope (and disruption) smaller. Even if you’re not ready to start work, a professional assessment gives you clarity and options.
