The honest part of this work is telling stable cracks from moving ones. A hairline or a stable crack under about a quarter inch is a seal-and-monitor job. A crack that is wide, offset, or growing after being filled is a symptom of base movement, and sealing it only buys time while the real cause, usually water or a failed base, keeps working. We tell you which one you have rather than selling a seal on a slab that needs more.
| What changes | Effect on your price |
|---|---|
| Total length of cracks and joints | Repair is priced by how much has to be routed, cleaned and sealed. Measure the running feet, not the number of cracks. |
| Stable or moving | A stable crack is a seal-and-monitor job. A crack that is wide, offset or growing is a symptom of base movement, and sealing it only buys time while the real cause keeps working. |
| Width and condition | Hairline cracks seal cheaply. Wide or spalled cracks need routing and more material. |
| Failed control joints | Cleaning and refilling joints that have lost their sealant is separate from crack repair and keeps water out at the joints. |
| Cause correction | If water or a failed base caused the cracking, fixing that is priced on top. Skipping it means paying for the repair twice. |
| Concrete truck access | Tight lots, long wheelbarrow runs and pump trucks all add labour to the exact same square footage. |
We check width, whether the two sides sit level, and whether it is still moving, because those tell us whether a crack is cosmetic, worth sealing, or a warning that the base is failing.
Stable cracks are routed out to a clean, consistent channel and the debris removed, so the sealant bonds to sound concrete rather than sitting on dust.
A flexible joint sealant is worked in that moves with the slab through freeze-thaw, instead of a rigid filler that cracks straight back out over a winter.
Failed or empty control joints are cleaned and refilled so they keep doing their job of giving shrinkage cracking a place to go.
If the cracking traces to water or a failed base, we tell you, because sealing the crack without fixing the cause just books the same repair again in a year or two.
