What each job class costs, why flooring dominates the price here, and the threshold that changes what licence the work requires.
What each job class costs
| Work | Typical range | What drives it |
|---|---|---|
| Mold remediation | $1,500–$6,000 | Extent, and how much porous material comes out |
| Whole-home remediation | $6,000–$15,000 | Multiple rooms plus contents handling |
| Slab moisture / rising damp | $2,000–$8,000 | Whether flooring bonded to the slab has to come up |
| Attic mold removal | $1,500–$5,000 | Access, and whether insulation is contaminated |
| Water damage restoration | $1,000–$8,000 | Water category far more than volume |
| Laboratory testing | $300–$800 | Number of samples sent |
| Inspection with moisture readings | Free | — |
Flooring is the line that decides the price
This is the local specific worth understanding before you read any quote. In Acadiana the dominant moisture path runs upward through slab-on-grade, so damage concentrates at floor level — baseboards, bottom plates, and whatever is bonded to the concrete.
Drywall and trim are inexpensive to remove and replace. Flooring adhered to a slab is not: it has to come up, the slab has to be prepared, and something has to go back down. Two quotes on the same house can differ by thousands purely on whether one of them plans to lift the floor.
So the question that makes quotes comparable is not "how much" but "what exactly are you removing, and what are you drying in place". Ask both bidders for that list.
The $7,500 line
| Project value | LSLBC Mold Remediation classification |
|---|---|
| Under $7,500 | Not legally required |
| Over $7,500 | Required — verify the number before signing |
Louisiana licenses mold work as its own trade, which most states do not. Above $7,500 the company needs the Mold Remediation classification specifically, not merely a residential or commercial licence. Holders are listed in a free public register searchable by name, number, city, parish, or contractor type — the full walkthrough is on the licence page.
One thing worth noticing without being cynical about it: a quote priced just under the threshold is not required to hold the classification. Plenty of jobs genuinely cost less. But it is worth asking what happens to the price when the wall opens and there is more behind it than expected.
What makes a cheap quote cheap
Usually that it is a cleaning rather than a remediation. Removing visible growth is straightforward and inexpensive. Identifying and correcting the water that produced it is the part that takes expertise, and it is the part a low quote tends to omit.
The test is one sentence: does the scope name where the water is coming from? Not "moisture intrusion" but the actual path — vapour through the slab, a fan discharging into the attic, a supply line weeping behind a cabinet. A scope without that sentence is priced to be cheap and scoped to come back.
Where money is best spent first
Cheapest to most expensive, and usually in this order: correct exterior drainage so standing water is not adding to the load, fix any fan discharging into the attic, then remediate what has already grown, and finally address vapour management under new flooring. Doing the last one first — laying new floor over a slab still passing vapour — is the most reliable way to pay twice.
Cost questions, answered plainly
What is the average mold removal cost in Lafayette?
Most remediation runs $1,500-$6,000, with whole-home work $6,000-$15,000. Slab moisture jobs run $2,000-$8,000, attic work $1,500-$5,000, and water damage restoration $1,000-$8,000. Inspections with moisture readings are free.
Why do two mold quotes differ so much?
Usually because they assume different amounts of material coming out. Drywall and trim are cheap; flooring bonded to a slab is not. Ask each bidder exactly what they are removing and what they are drying in place, and the totals become comparable.
Does the $7,500 licence threshold affect pricing?
It can. Above $7,500 an LSLBC Mold Remediation classification is required for the work. A quote landing just below that figure may be scoped honestly or may be scoped to stay under it - either way, ask what happens to the price if more material has to come out than expected.
Do I have to pay for an inspection?
Not with us. The visual inspection and moisture readings carry no charge anywhere we serve, and that includes reading another company's quote with you. Laboratory sampling, where it is genuinely needed, runs $300-$800.
Is mold removal covered by insurance?
Often partially, subject to a mold sublimit commonly around $5,000-$10,000 that applies even when the cause is covered. Sudden events like a burst pipe are usually covered; humidity and slab moisture are treated as building conditions and generally are not.
What makes a cheap quote cheap?
Most often, that it is a cleaning rather than a remediation. Removing visible growth without correcting the moisture source costs less and comes back. Check whether the scope names where the water is coming from - if it does not, the low price is explained.
Should I get several quotes?
Two well-documented quotes beat four vague ones. What makes a mold quote useful is a named moisture source, an explicit material list, a drying target, and a licence number you can verify. Four quotes missing all of that give you four prices and no information.

Describe what you have found and, if you can, how high up the wall it is. Growth that starts at the baseboard and works upward points somewhere very different from a stain that starts at the ceiling. That one detail often shortens the whole diagnosis. Expect a reply the same working day.
