What your job is likely to cost, and why
Most quotes in this trade are a single number with no working shown, which is why three of them never agree. This builds the number by addition and shows every line — including the site attendance minimum nobody advertises, and the four loadings that turn a cheap quote into an expensive variation.
Indicative estimate — not a quote
| Line | Low | High |
|---|---|---|
| Site attendance minimumCharged on every job. Nobody advertises this and everybody charges it. | $450 | $900 |
| Leaking crack in a concrete wall or slab — 8 linear metres of crack$200–$500 per linear metre | $1,600 | $4,000 |
| Patch and make good the drill holes | $160 | $400 |
| Indicative range | $2,210 | $5,300 |
Excluding GST. Long repetitive runs on one site drop toward the bottom of the band. A single short crack prices as a minimum job, not a rate.
What pushes this up: confined space, traffic management, after-hours access, overhead work, and reinstating a finish. Those four lines are the ones that go missing from a cheap quote and reappear as a variation.
What pulls it down: long repetitive runs on one site, open access, bare concrete left as is, and being able to do the work in normal hours.
