Rock does not move out of the way for a new road, a quarry face, or a hillside subdivision without help. In much of Tennessee that help is blasting. When a homeowner near the work finds a new crack in the foundation, a broken window, or drywall that split overnight, the first question is usually who pays.
Tennessee law gives part of the answer. Under Tennessee Code § 56-7-129, a company licensed to provide property insurance may subrogate a claim for damage caused by a blasting operation to the person causing the blast. In plain terms, if your property insurer pays a blasting-damage claim, the statute lets it pursue the blaster to recover what it paid.
Whether your own policy pays for a particular crack is a separate question. That depends on your policy forms, exclusions, and the facts of the loss.

What subrogation means for you
Subrogation is the insurer stepping into your shoes after it pays a claim so it can recover from the party that caused the damage. Background: TDCI’s glossary explains the difference between a first-party claim and a third-party claim.
For blasting, § 56-7-129 spells that right out. It matters to homeowners in two ways. First, your insurer has a clear path to the blaster, so a paid claim does not have to be the end of the story. Second, if your policy has a deductible and the insurer recovers from the blaster, ask how any recovery is shared with you. Your policy language controls that answer.
The blaster has to carry insurance too
Under the Tennessee Blasting Standards Act, each firm applying for or renewing a registration certificate must keep a current liability policy that includes blasting coverage, in the minimum amount of $1,000,000 during all blasting operations. The statute says the policy is for the use and benefit of any person who may be injured or aggrieved by a wrongful act or omission in the conduct of the blaster's business.
If that insurance policy ceases to be in effect, the firm registration certificate becomes invalid. One exception: the insurance section does not apply to a governmental entity as defined in the Tennessee Governmental Tort Liability Act.
Every blast leaves a paper trail
Tennessee Code § 68-105-107 says a record of each blast shall be kept. All records, including seismograph reports, must be retained at least three years and be available for inspection. The minimum data includes the name of the company or contractor; the location, date and time of the blast; and the direction and distance in feet to the nearest dwelling house not owned or leased by the blaster.
Those records can matter when you, your insurer, or an adjuster is trying to connect a specific blast to specific damage.
What to do if you suspect blasting damage
- Write down the dates and times you heard or felt blasts, and who is doing the work nearby.
- Photograph cracks, windows, and foundation lines with dates. Older photos of the same spots help.
