Blasting Next Door? What Tennessee Property Owners Should Do Before the First Boom

Quick answer: A pre blast inspection is a detailed, photo documented record of your property's condition before nearby construction blasting begins. A post blast inspection, sometimes called a blasting damage inspection, repeats the same documentation after blasting ends, so you can see exactly what changed. Absolute Inspectors provides pre blast and post blast inspections for homes and commercial buildings across Middle Tennessee, Nashville, Knoxville and Chattanooga.

If you live in Middle Tennessee, you have probably felt it. A thump through the floor, the windows rattle, the dog heads for the bedroom. Somebody down the road is building, and the ground underneath us is rock.

Middle Tennessee sits on limestone bedrock, and a lot of new roads, subdivisions, water plants and industrial parks cannot be built without blasting through it. That is not a knock on anybody. Builders have to get through the rock, and blasting is often the way to do it. But if you own the house or the building next door, you need to know where you stand, and you need a record of your property before the first boom, not after.

This is happening right now, close to home

This is not a someday problem. Here is what has made the local news in just the last year or so:

Hendersonville: NewsChannel 5 found about a dozen blasting complaints filed with the state over several months tied to an industrial park on Molly Walton Drive. Most of the people complaining lived about a mile away. The State Fire Marshal's Office reviewed the records and found no violations.
Franklin: In March 2026, neighbors near South Berry's Chapel Road reported new cracks in drywall and brick that they connect to blasting at a nearby subdivision project.
Wilson County: In October 2025, homeowners near Lebanon Road outside Mt. Juliet reported cracks in foundations, siding, drywall and driveways during blasting for a new water plant. The utility district said its seismograph readings were below the state limit.

Notice the pattern. Neighbors see cracks. The readings come back within limits. And everybody is left arguing about whether that crack was there before. That last question is the whole ballgame, and it is the one a pre blast inspection is built to answer.

What Tennessee law actually requires

Here is what the Tennessee Department of Commerce and Insurance, which oversees blasting through the State Fire Marshal's Office, tells consumers:

Pre blast surveys are only required within 300 feet. When the standard table of distance is exceeded, the blasting firm must offer a free pre blast survey to occupied homes, public buildings, schools, churches and commercial or institutional buildings within 300 feet of any blast hole. That survey documents existing structural and cosmetic flaws.
There are vibration limits. The state limit is 2.0 inches per second for ground vibration and 140 decibels for air blast. Blasting may be monitored with seismographs.
The state gets notice. You may not. The blasting firm has to notify the state of the exact blast location 72 hours before blasting begins. Firms are only required to warn people in the blasting area, so neighbors outside that zone may not get a heads up at all.
The state does not decide damage. The State Fire Marshal determines whether blasting standards were violated. It does not determine whether the blasting caused damage to your building. The state also says that whether or not the limits were exceeded, a property owner can still bring a civil action. For questions about a claim, the state points you to your insurance company or an attorney.
Your city cannot change the rules. Tennessee regulates blasting statewide, and local governments cannot make the requirements more or less strict.

Read that 300 foot rule again. In the Hendersonville case, most of the people complaining lived about a mile away. Nobody was required to offer them anything.

The free survey is good. Yours is better.

If a blasting firm offers you a free pre blast survey, take it, keep a copy, and walk through the house with whoever does it. There is nothing wrong with that survey.

But understand what it is. It is arranged by the blasting firm for the blasting firm's file. A pre blast inspection from Absolute Inspectors is one you order, for your file. You own the photos. You own the report. And if you are outside that 300 foot line, ours may be the only record you have.

What we document on a pre blast inspection

We walk the property the same way we would on any detailed property inspection, but with one goal: to record the condition of everything a blast could plausibly be blamed for, so there is no question later about what was already there.

Foundation and structure: visible foundation walls, crawlspace or basement, piers, slab edges and any existing cracks, with location and measured length and width
Brick, stone and mortar: veneer cracks, step cracking, separated mortar joints, lintels over windows and doors
Interior finishes: drywall and plaster cracks, nail pops, ceiling cracks, tile and grout
Doors and windows: which ones stick, which ones latch, and the gaps around them, because a door that suddenly will not close is often the first thing people notice
Concrete flatwork: garage slab, driveway, sidewalks and patios
Chimneys, retaining walls, pools and outbuildings where present
Time stamped photos and video of every room and every exterior wall, including the areas with no damage, because proving a wall was clean matters just as much as proving a crack existed

You get a report with all of it, typically delivered within 24 hours.

The post blast inspection

When the blasting is finished, we come back and repeat the same documentation in the same places. If a crack grew, we show it next to the original photo and measurement. If a new one appeared, we show where, how big and that it was not there before. If nothing changed, you have that in writing too, and that is good news worth having.

On longer projects that blast for months, some owners also have us check in partway through.

Here is our honest line on what we do and do not do. We document the condition of your property and what changed between visits. We do not assign blame, and we do not determine legal cause. That call belongs to a structural engineer, your insurance company or the courts. What we give them is the evidence they need to make it.

A few things to know before the first boom

Do not wait. The pre blast inspection only works if it happens before blasting starts. If blasting has already started, get one now. A record from today is a lot better than no record at all.
Look for existing cracks. The City of Hendersonville points out that many homes already have cracks from humidity changes, settling and normal wear. A lot of people never notice them until blasting gets them looking. That is exactly why a baseline matters.
Write down blast dates and times. If you feel a blast that seems unusually strong, note the date, the time and what you felt.
Know who to call. Blasting complaints go to the Tennessee State Fire Marshal's Office, online or at (615) 741-2241. Damage questions go to the contractor, your insurance company or an attorney.
Make temporary repairs if something could get worse, like a window that will not close before a storm, and photograph everything first.

For commercial owners, churches and HOAs

The same rules apply to commercial and institutional buildings within 300 feet of a blast. Offices, retail, warehouses, churches and schools often have more glass, more finishes and more tenants to answer to. We document commercial properties the same way, and we can cover multiple buildings or multiple homes in a neighborhood.

For developers and blasting contractors

We are not against your project. Tennessee needs the roads, the homes and the water plants. If you need a third party to document neighboring properties before you blast, call us. A clean, independent record protects everybody.

Why Absolute Inspectors

We want to be clear about one thing: we are not code inspectors. Enforcing building code is the job of your local building department.

Frequently asked questions

What is a pre blast inspection?

A detailed, photo and video documented record of a property's condition, including existing cracks, before nearby construction blasting begins.

Is the blasting company required to inspect my home?

In Tennessee, when the standard table of distance is exceeded, the blasting firm must offer a free pre blast survey to occupied buildings within 300 feet of any blast hole. Properties farther away are not required to be offered one.

What is the vibration limit for blasting in Tennessee?

The state limit is 2.0 inches per second for ground vibration and 140 decibels for air blast, according to the Tennessee Department of Commerce and Insurance.

Can you tell me if blasting caused my cracks?

We document what your property looked like before blasting and what changed after it. Deciding legal cause belongs to a structural engineer, your insurer or the courts. Our before and after record gives them the facts to work with.

Blasting already started. Is it too late?

No. Get your inspection as soon as you can. A record from today still protects you from anything that happens after today.
