What a concrete workmanship warranty is for
Every concrete contractor knows the saying: concrete cracks. Customers do not, and a hairline crack can feel like a defect to them. A written warranty that explains control joints and normal shrinkage cracks, covers real failures from your base or finishing work, and excludes salt, heavy trucks and roots, sets expectations before the pour, not after the first winter.
What to put in a concrete workmanship warranty
- What counts as a defect: settlement or heaving from your base work, scaling from finishing.
- Normal shrinkage cracking and control joints.
- Exclusions: de-icing salts, heavy vehicles, roots, drainage changes.
- Color variation and surface marks.
- Sealing and care the customer should do.
- How to make a claim.
What a concrete warranty usually leaves out
- Hairline and shrinkage cracks, especially between control joints.
- Scaling caused by de-icing salts.
- Damage from vehicles heavier than the slab was built for.
- Movement from tree roots or changes in drainage.
- Color differences between pours.
How to fill it in
- Fill in the customer, the job and the date the work finished.
- Set your warranty period.
