Flooring Contractor Insurance: What It Actually Costs and Covers

General liability insurance for a flooring contractor typically costs $720 to $1,080 a year for comprehensive coverage, with bare-minimum starter policies available closer to $500 a year.

How much does general liability insurance cost for a flooring contractor?

• Median standard policy: around $63/month ($759/year) for $1M/$2M GL
• Comprehensive coverage: $720 to $1,080 a year ($60-$90/month)
• Bare-minimum starter policy: as low as $500 a year
• Costs rise for commercial buildouts versus residential work, and vary meaningfully by state (higher in NY/CA, lower in NC/TX)

$1 million per occurrence / $2 million aggregate with a $500 deductible is the standard GC requirement, same as other construction subs.

What's the difference between CG 20 10 and CG 20 37, and why does it matter?

This is the single most misunderstood coverage detail in the flooring trade. CG 20 10 makes a general contractor an additional insured only for ongoing operations, while you're actively on the job. CG 20 37 extends that to completed operations, claims that surface after the job is finished. Flooring failures, subfloor moisture, adhesive failure, board cupping, often don't show up until months after installation. A flooring sub carrying only CG 20 10 can leave both the GC and the sub exposed on exactly the claim type most likely to actually happen in this trade. Being named an additional insured under CG 20 10 alone does not protect you from the moisture and adhesive claims that show up after your crew has left.

Who's liable when hardwood flooring cups after installation?

It depends on the cause. Cupping, where board edges curl upward, traces back to excess subfloor or slab moisture at the time of install. If the installer failed to test moisture content or properly acclimate the wood before installing, that's installer liability. If it's a pre-existing slab or subfloor condition the GC should have disclosed, liability shifts toward the GC instead. This is a real, recurring post-completion dispute pattern, not a rare edge case.

Does silica dust exposure apply to flooring work too?

Yes, cutting tile or stone falls under the same OSHA 2016 respirable crystalline silica rule that covers masonry and concrete cutting, an 80% cut from the prior exposure limit down to 50 micrograms per cubic meter, fully enforced since September 2017. This matters even more where flooring crews also cut engineered stone or quartz: California's Department of Public Health has documented 592 silicosis cases among stone-fabrication workers since January 2019, including 65 lung transplants and 31 deaths, with a Colorado jury awarding $17.45 million to a 31-year-old fabricator in May 2026.

What bonding applies to flooring contractors?

State requirements vary: California splits flooring (C-15 license) from tile (C-54 license) as separate classifications, each requiring a $25,000 bond. Washington requires a $12,000 general bond or $15,000 for specialty work. Only 19 states require a state-level bond at all, the other 31 leave it to county or city permitting.
