The policies an insulation business carries
Insulation contractors work in attics and crawl spaces, so a foot through a ceiling, a blocked vent and fumes or odors from spray foam are the claims to plan for.
| Policy | Average a month |
|---|---|
| General liability | $83 |
| Tools and equipment | $42 |
| Commercial auto | $270 |
| Workers' compensation | $160 |
| Surety or license bond | $9 |
Averages are what Insureon's customers among contractors as a group (it publishes no separate figures for insulation) pay, from Insureon's cost page; most of its customers have fewer than five employees. Across all its small business customers, general liability runs $265 to $3,030 a year.
Claims insulation contractors plan for
- A worker steps through a ceiling in the attic
- A soffit vent is blocked and the attic grows mold
- Spray foam odor keeps a family out of the house
- Blown-in insulation covers a recessed light that overheats
Ask your agent, in these words:
- Would my policy pay if a worker steps through a ceiling in the attic?
- Would my policy pay if a soffit vent is blocked and the attic grows mold?
- Would my policy pay if spray foam odor keeps a family out of the house?
- Would my policy pay if blown-in insulation covers a recessed light that overheats?
Name the work you sell
A policy covers the work you describe on the application. From the insulation services list, name each of these and ask whether any is excluded: blown-in insulation; batts or rolls; old insulation removal; air sealing; closed walls, drill and fill; spray foam, open-cell; spray foam, closed-cell; rigid foam board; crawl space encapsulation; rim joist sealing.
The blowing machine and any spray foam rig are the big items to list. On the tools list, the items to list on the policy are thermal camera; spray foam rig; dense pack wall setup; insulation removal vacuum; box truck or trailer, and from the starter kit, insulation blowing machine (rent or buy); blowing hose and fittings; insulation knife and a straightedge; staple hammer; respirator, coveralls, goggles and gloves.
State rules in the license
Insulation work often falls under the general contractor rules. Our general contractor license guide lists the insurance and bond line for each of 48 states from the boards' own pages.
Workers' comp and bonds
The SBA says every business with employees must carry workers' compensation, unemployment and disability insurance. Insureon's average for contractors as a group is $160 a month, priced per $100 of payroll. A bond protects the state or the customer, not you; Insureon puts its yearly cost at a share of the bond amount:
| Bond amount | Estimated yearly cost |
|---|---|
| $5,000 | $25 to $500 |
| $10,000 | $50 to $1,000 |
| $50,000 | $250 to $5,000 |
Certificates of insurance
Builders, utility programs and property managers ask for a certificate before work starts. Keep a PDF on your phone so you can send it the day they ask.
