Sagging Floor Repair in Geelong
A sagging floor means something underneath has moved: sunken or rotten stumps, a failed bearer or joist, or plain long-term settlement. The right fix ranges from packing and relevelling to partial restumping, and diagnosis decides which. A free inspection with a laser level and a subfloor crawl answers it before you spend anything.
- Free inspections
- Itemised quotes
- Permits handled
Every sagging floor is a symptom, and treating symptoms is how people pay for the wrong repair. A dip in the hallway might be one rotten joist. A whole room running downhill is usually stumps. A bouncy lounge room can be undersized bearers doing their best since 1955. The repair only makes sense once the cause is pinned down.
Diagnosis is straightforward when it's done properly. A laser level maps how far the floor has moved and in which direction. Under the house, the story is usually written plainly: crushed stump tops, a bearer pulling away, damp soil in one zone. Ten minutes with a probe sorts settled stumps from rotten ones.
Fixes run from cheap to structural. Sound stumps that have settled get packed and relevelled. Rotten timber gets replaced. Failed stumps get swapped in a partial restump. Restumping Geelong quotes only what the diagnosis supports, in writing, with photos of what we found. Book a free inspection and get a straight answer.

Frequently Asked Questions
Why is my floor sagging?
The common causes: stumps that have sunk or rotted, bearers or joists weakened by damp or termites, or gradual settlement into reactive clay soil. Occasionally it is simply an old, lightly built floor flexing under modern loads. Which one it is changes the repair completely, which is why inspection comes before any quote.
How do you fix a sagging floor?
It depends on the cause. Settled but sound stumps are packed back to level. Rotten joists and bearers are replaced or reinforced. Failed stumps are replaced in a partial restump. Costs differ by thousands between those answers, so no honest contractor quotes a sagging floor sight unseen.
Is a sagging floor dangerous?
Rarely an emergency, but always a progression. Floor structures have redundancy, so they sag long before anything gives way. The real cost of waiting is secondary damage: cracking plaster, jamming doors and racking frames worsen as the sag grows, and the repair bill grows with them.
Can I fix a bouncy floor without restumping?
Often, yes. Bounce usually points at the timber between stumps rather than the stumps themselves: long joist spans or a tired bearer. Extra support under the right spot can firm it up at a fraction of restumping cost. The subfloor crawl tells us whether you're in that lucky category.
