The best time of year to restump in Shepparton.
Most people assume summer, because the weather is good. The clay disagrees. Here is how the Goulburn Valley’s wet-dry cycle actually affects a restump, when the season genuinely changes the outcome, and when it honestly does not matter at all.
Why the answer is autumn, not summer.
Autumn and late spring, for a reason most people find backwards. The reactive clay under Greater Shepparton is at its wettest and most swollen in late winter and its driest and most shrunken by late February, and if you set a floor dead level at either extreme you have set it to a condition the ground only visits once a year. April to May and October to November are the shoulders, when the clay sits nearer the middle of its range, and a floor levelled then reads true for more of the year. That said, this matters far more for levelling-only work than for a properly footed restump.
Put numbers on it and it stops being abstract. Under AS 2870, much of this district classifies as Class M to Class H1 reactive clay, meaning characteristic surface movement in the order of 20mm to 60mm through a full wet-dry cycle. Shepparton gets roughly 480mm to 500mm of rain a year, spread thinly, against ferocious summer evaporation, so the ground genuinely does swell through winter and shrink hard through a run of 35 and 40 degree days. Level a floor to the February reading and it can sit high by winter. Level it to the September reading and it drops away by autumn.
And why it mostly stops mattering.
Here is the part a lot of operators will not tell you, because it makes the seasonal argument less dramatic. The season affects the reading, not the result, provided the footings are right. On a restump where every stump sits on an engineered pad founded below the active clay zone, the house is anchored to stable ground and the seasonal cycle above it stops mattering. On a levelling-only job, where the existing stumps stay and we are packing or adjusting to bring the floor back to true, the season absolutely matters, because you are levelling to whatever the ground is doing that week. That is one of the strongest arguments for galvanised steel adjustable stumps in this district: a corner can be trimmed later with a spanner. The full argument sits on our stump lifespan page, and it comes down to the same thing every time. You are buying footings, not stumps.
What each part of the year is actually like.
Summer (December to February): hard ground, hard conditions.
Not more expensive on the rate card, but it can cost more in practice through the difficult-access loading. By February the clay here has been drying since November and can be genuinely hard to dig, which slows the excavation for every footing. Shepparton regularly sees days over 40 degrees and a subfloor with no airflow is hotter still, so crews start at first light and lose the afternoon. That is why the difficult-access surcharge of 10% to 25% turns up more often on midsummer jobs with tight crawl spaces. The stumps themselves are the same $60 to $110 for concrete or $90 to $160 for galvanised steel whatever the month.
Autumn (March to May): the sweet spot.
The clay has taken its first proper rain and softened but has not gone to mud. Digging is reasonable, the crawl space is workable, concrete cures at a sensible rate, and the ground sits near the middle of its seasonal range. Autumn is also when the phone runs hottest, because a dry summer has just finished pulling floors down and the doors that closed at Christmas no longer do. Book ahead.
Winter (June to August): easy to book, wet underneath.
Yes, we work through it, and winter is often the easiest booking to get. The trade-offs are practical rather than structural: the clay is wet and holes want to hold water, the crawl space is cold and damp to work in, and concrete takes longer to cure in single-digit mornings, which stretches the schedule slightly. Against that, the ground digs far more easily than sun-baked February clay, and lead times are usually shorter because the phone runs quieter. Nothing about winter compromises the finished job when the footings are designed properly.
Spring (September to November): drying out, opening up.
Early spring is the wettest the ground gets and the least useful time to take a level reading. By late October and November it has drained back toward the middle and conditions are close to autumn quality. Spring is also when flood risk on the Goulburn is at its highest, which is worth remembering if you are in a low part of Shepparton North or near the river.
Lead times, and the Christmas trap.
Allow one to three weeks for the engineer’s footing design and the building permit before anything happens on site, then the job itself. Demand is seasonal and predictable: enquiries spike from late summer into autumn, when a dry season has pulled floors down far enough that doors stop closing, and again after any significant flood event. Mid-winter is the quietest stretch. The one trap is the Christmas period, because surveyors and engineers shut down and a permit lodged in mid-December can sit until February. If you want work done in autumn, start the paperwork in summer.
That permit window is the piece of the timeline nobody controls, including us, and it is worth understanding before you plan around a date. What Greater Shepparton and the private surveyors actually require is set out on our permits page.
A worked example of the seasonal difference.
A 46-stump weatherboard with 34 perished stumps in the failed rows, concrete at $85 installed, is $2,890 of stump work in any month of the year. Add the full re-level at $2,700, engineering at $850 and the permit at $1,050 and that partial restump is $7,490 regardless of season. Now run it in mid-February with a 500mm crawl space over concrete-hard clay: the difficult-access loading applies at, say, 15%, and the job goes to roughly $8,600 and takes three extra days. Run the identical house in May and the loading does not trigger. The season did not change the engineering, the standard or the outcome. It changed about $1,100 and a week. Full rates are on our pricing page, and the mechanics of the job itself are on our restumping page.
Questions about timing a restump.
What is the best time of year to restump a house in Shepparton?
Autumn and late spring, for a reason most people find backwards. The reactive clay under Greater Shepparton is at its wettest and most swollen in late winter and its driest and most shrunken by late February, and if you set a floor dead level at either extreme you have set it to a condition the ground only visits once a year.

That said, this matters far more for levelling-only work than for a properly footed restump.
Can you restump in winter in the Goulburn Valley?
Yes, and winter is often the easiest booking to get. The trade-offs are practical rather than structural: the clay is wet and holes want to hold water, the crawl space is cold and damp to work in, and concrete takes longer to cure in single-digit mornings, which stretches the schedule slightly. Against that, the ground digs far more easily than sun-baked February clay, and lead times are usually shorter because the phone runs quieter. Nothing about winter compromises the finished job when the footings are designed properly.
Does restumping in summer cost more in Shepparton?
Not on the rate card, but it can cost more in practice through the difficult-access loading. By February the clay here has been drying since November and can be genuinely hard to dig, which slows the excavation for every footing.

Does the season affect how level the house ends up?
It affects the reading, not the result, provided the footings are right. On a restump where every stump sits on an engineered pad founded below the active clay zone, the house is anchored to stable ground and the seasonal cycle above it stops mattering. On a levelling-only job, where the existing stumps stay and we are packing or adjusting to bring the floor back to true, the season absolutely matters, because you are levelling to whatever the ground is doing that week. That is one of the strongest arguments for galvanised steel adjustable stumps in this district: a corner can be trimmed later with a spanner.
How far ahead should I book a restump in Shepparton?
Allow one to three weeks for the engineer’s footing design and the building permit before anything happens on site, then the job itself.
