Why nobody publishes this
Search mold removal pricing and you will mostly find national averages scraped from lead-generation sites, or a page that promises a free quote and asks for your phone number. There is a reason for that, and it is not that the number is unknowable.
It is that a price is easier to defend in your kitchen than on a screen. Once a company has spent an hour with you and pointed at a wall, a large figure lands differently than it would have if you had read it over coffee two days earlier.
We would rather you read it over coffee. If our range does not work for you, finding that out now costs both of us nothing. If it does, you already know roughly where you stand when we walk in.
The four price ranges
Nearly every residential job we take falls into one of these.
| Price range | Cost | What is usually involved |
|---|---|---|
| Minimum | From $600 | One contained area — a closet, a section of wall, a bathroom ceiling. Containment, removal, treatment, and the evaluation that got us there. |
| Small | $1,000 – $2,500 | A single room, or a limited area where some material has to be cut out and hauled off. |
| Medium | $2,500 – $5,000 | More than one room, or growth that has gotten inside wall cavities or into the HVAC system. |
| Large | $5,000 and up | Widespread growth, significant demolition, or treating a whole house at once. |
Most mold remediation in Louisiana lands between $1,000 and $5,000. Where a specific job falls depends on the area affected, the materials involved, how much has to physically come out, and whether the air handler has been circulating spores through the rest of the house.
Our minimum is $600. Most mold companies set theirs between $1,000 and $1,500. A closet should not be priced like a whole floor, and a minimum that starts at $1,500 quietly tells you the small jobs are not worth their time. They are worth ours.
Mold removal cost calculator
This uses the same price ranges above and the same logic we use on site. It gives you a range, not a quote — nobody can price a house they have not walked through, and any company that does is guessing or padding. But it will get you close enough to know what conversation you are having.
A small contained job. This is the range most single-spot problems land in.
What this deliberately does not do
It does not ask for your name, your email or your phone number to show you the answer. You are trying to find out what something costs. That is not a lead, it is a question, and it should not cost you a week of follow-up calls to get it answered.
Mold fogging cost calculator
Mold fogging — dry fog, as the trade calls it — is priced differently from the ranges above, because it is not priced by how much has to come out. It is priced per square foot of the area being treated, so the arithmetic is simple enough to publish.
| Line | Rate | What it is |
|---|---|---|
| Dry fog treatment | $2.50 / sq ft | The treatment itself, applied through the living area |
| Air scrubbing | $0.20 / sq ft | Filtering the airborne spores out rather than leaving them to settle |
| Together | $2.70 / sq ft | What a whole-home dry fog treatment normally runs |
Based on the square footage of the living area — the conditioned space, not the lot and not the garage.
Ceiling height does not change the price. Eight feet or twelve feet, the equipment, the chemical and the setup are effectively identical, so charging by cubic volume would only be a way of making the number bigger. We price on total living area. A commercial building with genuinely high ceilings — forty feet, say — is a different conversation, but no house is.
Enter the square footage of the living area.
Tell us you used this calculator and we take off the air scrubbing or $250, whichever saves you more. No code to enter and nothing to print. Just say it when you call.
When mold fogging is the right answer — and when it is not
It treats a whole property rather than a located spot, which makes it the tool for several situations that traditional removal handles badly:
When the air conditioning system is involved. Once mold is in the air handler or the ducts, the system has been distributing it to every room it reaches. There is no single wall to open, and this is where fogging does its best work.
When the house has already been cross-contaminated. Very common: a homeowner opens the walls themselves to see how bad it is, with no containment. The growth was in one room, and now the spores are through the house. Fogging treats what got spread, which nothing else practically can.
When the counts are high and nobody can find it. Airborne spore counts come back elevated and neither you nor the assessor can locate growth. Nothing to cut out, but the air says something is there.
Alongside traditional removal, not instead of it. On a lot of jobs it is both: the failed material comes out, and the fog handles the cavities and the air that removal alone would leave behind.
Where fogging is the wrong tool on its own: material that has physically failed. Sheetrock gone soft has to come out, and no treatment changes that. If we look at your house and traditional removal is what it needs, that is what we will tell you, even though this page makes the other one easier to quote.
What actually moves the number
How much has to be cut out
This is the biggest single factor, and it is not the same as how big the stain is. A patch of growth on the paint is cheap. The same patch, where the sheetrock behind it has gone soft, means opening the wall, hauling material off, and putting it back.
Whether the HVAC is in it
An air handler that has been running with mold in it has been distributing spores to every room the ductwork reaches. That turns a one-room job into a whole-house job, and it is the most common reason a price comes in higher than somebody expected.
What the material is
Sheetrock is fast to remove and cheap to replace. Plaster and lath, common in older New Orleans housing, holds moisture longer and costs more to open and restore. Tile, cabinetry and hardwood all sit somewhere in between.
Whether the cause is fixed
Not a line item, but it decides whether you pay once or twice. If the roof, the drain line or the leak that fed the mold is still doing it, the remediation is a temporary result. We find the source as part of the evaluation and can bring in the trade that corrects it.
Access
A crawl space you cannot stand up in, an attic in August, a second-floor room reached through the rest of the house — these change how long the work takes and how much containment it needs.
Mold fogging or traditional
Fogging for mold reaches cavities that cannot easily be opened, which often means less demolition and a lower total repair bill. Traditional removal is the honest answer when material has physically failed. We do both, and which one applies is a finding, not a preference.
What the price includes
- The evaluation. Free, and it is not a sales call with a clipboard. We look past the spot you called about, at the places mold tends to sit that a homeowner would not think to check, and we look for where the water came from.
- Containment. Sealing the work area and holding it under negative air pressure, so that removing mold in one room does not seed the next one.
- Removal and treatment. Whatever the job calls for — physical removal, mold fogging, or both.
- Haul-off. The material that comes out goes with us.
- A written scope, before anything starts. Not a verbal figure. What we are doing, where, and what it costs.
What it does not include is testing, because Louisiana does not permit us to do both. See below.
Will insurance pay for it?
Usually not. That is the honest answer, and it surprises most people.
Mold is not standard coverage. On modern policies it is a rider — something you pay extra for. If you never added it, you do not have it, whatever else your policy covers. Most homeowners find this out on the phone, after they already have a problem.
When it exists, it is capped. In the jobs I have worked where insurance actually paid for mold, the rider was capped at one of three numbers: $3,000, $5,000, or $10,000. Those are the only limits I have ever seen. And that is a total, not a per-room or per-occurrence figure — it is the whole pot.
Long-term problems get denied. This is where most claims die. A roof that has leaked for months. A pipe you knew was dripping. A wall that has been damp since last summer. Insurers treat those as maintenance you did not do, and they will deny the claim even if you carry the mold rider. Sudden and accidental is covered. Neglected is not.
And when a pipe bursts, the mold work usually never becomes a mold claim. The water mitigation crew gets there first — they cut out the wet material, spray antimicrobial and dry the structure. That is water damage, not mold, and it comes out of a different part of your policy. Done fast enough, the mold never gets going.
So the real answer is: sometimes, in specific circumstances, up to a capped amount. Plan on paying for this yourself. If coverage comes through, treat it as a bonus.
Why a mold-only company exists
Most people cannot name a mold company. Ask around and you will get restoration companies — the ones that do water, fire and mold together — because those are the names on the trucks after a storm.
There is a reason for that, and it is worth understanding before you call anyone.
Full-service restoration runs on insurance work. Water damage and fire damage are covered losses. The claim gets filed, the adjuster approves it, the work gets scheduled. That is a volume business and it works.
Mold usually is not a covered loss. As above — it is a rider most people never bought, capped low, and denied outright when the problem has been building for months. So mold does not fit that model. A full-service company will take the job if it lands in front of them, but it is not what they are built to chase, and it is not where their crews spend their weeks.
And traditional remediation is slow, careful work. Containment that actually holds. Negative pressure maintained for the length of the job. Knowing how far past the visible growth to cut, and stopping in the right place. It does not scale the way a water loss does, and there is no adjuster on the other end approving the hours.
That gap is the reason specialists exist. Mold is the only thing we do, which means our overhead is sized for it, our equipment is bought for it, and a small job is still worth doing properly.
Testing is a separate cost, and a separate company
Louisiana licenses mold assessment and mold remediation separately, and it is a violation for one company to perform both on the same property. The rule exists for an obvious reason: a company paid to find mold, and then paid again to remove what it found, has an interest in finding a lot of it.
So if you want air sampling or lab identification, that is an independent assessor and their own fee, and we will point you to one. Whether you need it at all depends on what you are trying to answer — visible growth on a bathroom ceiling does not need a lab to confirm it is mold.
How to read a quote that is not ours
A price with no written scope
A number on its own is unenforceable. If it does not say what is being removed and from where, there is nothing to hold anybody to when the job changes halfway through.
“We’re fully insured” with no certificate behind it
Mold is commonly excluded from general liability by the standard fungi or bacteria exclusion, which removes both the liability and the cost of remediation — so even a large policy can cover none of your job. Louisiana raised the mold remediation minimum to $500,000 in August 2026, which also means a license issued earlier does not prove the coverage behind it still qualifies. Ask for a current certificate showing the general liability is rated for mold. We are fully insured for mold remediation and send ours on request — ask anybody else you call for theirs.
Testing and remediation on the same invoice
In Louisiana that is not a red flag, it is a licensing violation. You can verify any contractor's license with the state board.
A price that arrives before anyone has looked
Either it is padded to cover the unknown, or it is low enough to win the job and will grow once work starts.
Nobody asked where the water came from
If the conversation was entirely about the mold and never about the moisture, you are buying a result with a shelf life.
Charging for the estimate
It is common, and it is why people wait until a $600 problem is a $4,000 one. Ours is free.
Common questions
How much does mold removal cost in Louisiana?
Our minimum is $600 for a small contained area. Small jobs generally run $1,000 to $2,500, medium jobs $2,500 to $5,000, and larger jobs start at $5,000. Most mold remediation in Louisiana falls between $1,000 and $5,000. The on-site evaluation that produces your number is free.
Does homeowners insurance cover mold?
Usually not. On modern policies mold is a rider you have to add and pay extra for — it is not included by default. Where it does exist, every capped limit I have seen has been $3,000, $5,000 or $10,000 total. Claims from long-term problems, such as a roof or pipe that has leaked for months, get denied as deferred maintenance even when the rider is in place. A sudden burst pipe is the exception, and that is usually handled as water damage by a mitigation crew before it becomes a mold claim at all.
Who pays for mold remediation?
In most cases the homeowner does. Insurance pays only when a mold rider was purchased in advance and the cause was sudden and accidental rather than a long-running leak, and even then it is capped. Assume the cost is yours and budget for it — the free evaluation gives you the real number before you decide anything.
Is there a mold removal cost calculator?
Yes — there are two on this page, and both are free. The mold removal cost calculator asks for the affected area and the conditions, and returns the price range your job is likely to fall in. The mold fogging calculator does the same for whole-structure treatment. Neither replaces the on-site evaluation, which is also free and is what produces the actual figure.
How much does mold removal cost per square foot?
Dry fog is priced per square foot: $2.50 per square foot for the treatment and $0.20 per square foot for air scrubbing, so $2.70 per square foot together, based on the living area rather than the lot or the garage. Ceiling height does not change it. Traditional remediation is not priced per square foot, because the cost is driven by how much material has to come out rather than by floor area — that is why it is quoted in the ranges above.
How much does mold removal cost in Baton Rouge?
The same as everywhere else we work. The minimum is $600 for a small contained area, small jobs generally run $1,000 to $2,500, medium jobs $2,500 to $5,000, and larger jobs start at $5,000. Mold removal cost in Baton Rouge, New Orleans, Metairie, Denham Springs and the surrounding parishes all fall in those ranges — what varies is the house, not the zip code.
Why is your minimum lower than everyone else's?
Because mold is all we do, our overhead is not a franchise's, and we do not mark up subcontractors. A company running water, fire, smoke and biohazard work carries the cost of all of it, and small mold jobs stop being worth dispatching a crew for. We would rather take the closet now than the whole wall next year.
Can you give me a price over the phone?
We can tell you which range it is likely to be, which is often all somebody needs to decide what to do next. We cannot give you a firm number, because the thing that sets the price is usually what is behind the wall rather than what is on it. The calculator above does roughly what we would do on the phone.
Do you charge for the evaluation?
No. Charging to show up means people wait until it is worse, and a mold problem that waits does not stay the same size.
Do you offer payment plans?
Talk to us. Where a job is large enough that timing is the obstacle, we would rather find a way to schedule it than have somebody live with it.
Is a cheaper quote from another company a bad sign?
Not automatically. Compare the scopes rather than the totals. A lower price for less work is not cheaper, it is smaller, and the difference tends to show up as the part of the wall nobody opened.
Mold removal cost by area
Price does not change by city. A closet in Baton Rouge costs what a closet in Slidell costs. What changes is the houses. An older place in New Orleans hides different problems than a new build in Prairieville, and that shows up in what we find once the wall is open.
