Boise Custom Builder — Slab Crack Defect Claim
Two years after a Boise custom build closed, the homeowner reported significant slab cracks in three rooms. Forensics identified moisture-conditioning protocol failures during install — the substrate hadn't been allowed to cure under HVAC-controlled conditions before slab placement. The homeowner sued for $62,000 in remediation costs. The contractor's CGL excluded "your work" on the slab itself.
Pulled the CGL alongside the original install schedule and the manufacturer's curing-protocol requirements. CGL covered surrounding finish damage but excluded the slab work. Brought in a contractors E&O policy quote that would have responded to the moisture-conditioning design-spec issue.
Contractor paid $38,000 for the slab work out of pocket; surrounding damage covered by CGL. New program includes contractors E&O for faulty-workmanship exposure. Idaho's lighter regulatory framework masks the reality that workmanship-defect claims hit specialty trades just as hard as in California — with less coverage in place to absorb them.
