| Inspection with moisture readings | Free; small exploratory openings, if needed, $300–$1,200 | Whether readings point inside a wall |
| Mold remediation, one area to a few rooms | $1,500–$6,000 | How much drywall, insulation or flooring has to leave |

| Air handler and duct mold | $1,000–$4,000 | Duct type, and whether the air handler is involved |

What makes a Sulphur quote higher or lower?
- Porous material that has to go. Drywall, insulation, carpet and pad soak up water and are usually cut out and bagged. Framing and roof decking are usually cleaned and treated in place.
- Whether the mold is inside a wall. Growth on the face of drywall is a smaller job than growth across the stud bays behind it, which is why wall cavity work has its own range.
- Clean or dirty water. Water from a supply line is handled differently from storm or flood water, and that matters more to the price than the number of gallons.
- Containment. Plastic walls, negative air and HEPA filtration add cost, and they're worth it on anything bigger than a small patch.
- Fixing the moisture. A roof repair, a drain line, duct insulation or a dehumidifier may be quoted separately. Without it, the mold comes back.
Why wall openings are priced separately
NWS Lake Charles called Laura's wind and surge damage major to catastrophic across Calcasieu Parish, and many Sulphur houses had roofs, ceilings or walls repaired after Laura and Delta in 2020. When a moisture meter reads high on a wall that looks fine, the only way to know what's behind it is to open a small section. In the Lake Charles area that runs $300–$1,200, and the price is agreed before anyone cuts. Sometimes the framing behind is dry and sound, and the job ends with a patch. If mold is there, the opening becomes the first step of the remediation.
How do you compare two mold quotes?
- Does it name the moisture source, and say who fixes it?
- Does it list materials removed by the square foot, or only surfaces "treated"? A treatment-only quote is a cleaning, not a removal.
- Is containment included for anything larger than a small area?
- Is lab testing there for a reason, or added by habit?
- Is there a final moisture check before walls are closed?
Two Louisiana-specific checks. If the total is over $7,500, the contractor needs a Mold Remediation license from the Louisiana State Licensing Board for Contractors; ask for the number. And if the fix includes roofing or re-roofing that starts on or after August 1, 2025, Act 239 requires a permit and inspection, handled inside city limits by the City of Sulphur Inspections & Permits Department (110 N Huntington).
Cost questions
How much is professional mold removal in Sulphur?
Most jobs fall in the $1,500–$6,000 remediation range. Mold inside wall cavities runs $2,000–$8,000, and whole-house jobs $6,000–$15,000. These are Lake Charles-area ranges; a written quote after the free inspection is the number that counts.
Why can't anyone give me a firm price over the phone?
Because the price depends on what's wet and what's behind the surface. Two stains that look alike can be a one-day cleanup or a wall that has to come apart. Moisture readings take the guessing out, and the inspection costs nothing.
Will homeowners insurance pay for mold removal in Louisiana?
It depends on the policy and the cause. Mold that follows a sudden covered event, like a burst pipe, is more often covered than mold from humidity or a slow leak, and many policies cap mold coverage. Call your insurer and photograph the damage before work begins.
Does Louisiana's $7,500 license rule apply to my job?
Only if the mold remediation work exceeds $7,500. Above that, the contractor must hold an LSLBC Mold Remediation license. Many single-room jobs come in under the line; whole-house and multi-wall jobs often don't.
