Common mold questions for Lafayette, LA. Most remediation runs $1,500–$6,000; the dominant local cause is vapour rising through slab-on-grade over a high water table; and Louisiana requires a licence above $7,500 that you can verify publicly.
Moisture from below the floor
Why does mold keep coming back at my baseboards?
Because the supply has not stopped. Acadiana sits on a high water table with mostly slab-on-grade housing, and concrete is not a vapour barrier - moisture moves up through it continuously. Removing growth without addressing that vapour puts the same material back into the same conditions.
My floors are cupping. Is that mold?
It is moisture, which is the thing that causes mold. Flooring cupping, lifting, or losing adhesion over a slab is a strong indicator that vapour is coming up through the concrete. Whether growth has started is a separate question answered by opening a small area.
Can I just put new flooring down?
Not without testing the slab first, or you will be doing it twice. Laying new flooring over a slab still passing vapour puts new material into the conditions that destroyed the old. A slab moisture test before the floor goes down costs a fraction of repeating the job.
Moisture from above the ceiling
Where does attic mold come from here?
Most often a bath or dryer fan discharging into the attic instead of outside - a shower's worth of wet air delivered into a cool space twice a day for years. After that, wind-driven roof leaks and ducts sweating in summer heat.
Does staining on roof decking mean I have a problem?
Not always. Old water staining from a leak repaired long ago looks similar to active growth from a ladder. The separator is whether the material is currently wet, which is a moisture reading rather than a judgement by eye.
Will I need the roof decking replaced?
Rarely. Surface growth on structurally sound decking is cleaned and treated. Replacement is for material that has gone soft, is delaminating, or has rotted - conditions you can demonstrate by pressing on it. A quote proposing wholesale replacement for staining deserves a second opinion.
Moisture from outside, all at once
How fast do I need to act after water gets in?
Mold can begin on wet organic material within roughly 24 to 48 hours. At 62.8 inches of annual rainfall with high ambient humidity, opening windows adds moisture rather than removing it. Mechanical drying started inside that window changes the size of the job substantially.
Why is flood water treated differently from a burst pipe?
Flood water is treated as contaminated, so porous materials it touched come out rather than being dried. Clean supply water caught quickly can often be dried in place. Category drives the scope more than volume does - a small flood outscopes a large clean leak.
What is a flood cut and do I really need one?
Removing drywall to a set height above the water line so the wall cavity and insulation can be dried or replaced. It looks drastic and it is standard, because insulation holds water long after the drywall surface feels dry. Drying a flooded wall without opening it is how mold grows invisibly.
Money, licensing, and who to hire
How much does mold removal cost in Lafayette?
Most remediation runs $1,500-$6,000 and whole-home $6,000-$15,000. Slab moisture work is $2,000-$8,000 and attic $1,500-$5,000. The biggest variable is whether flooring bonded to the slab has to come up.
Does Louisiana license mold contractors?
Yes, above $7,500, under an LSLBC Mold Remediation classification requiring 24 hours of board-approved training. Holders are in a free public register searchable by name, number, city, parish, or contractor type. Most states have no equivalent check.
Will insurance pay for it?
Often partially, subject to a mold sublimit commonly around $5,000-$10,000. Sudden events like a burst pipe are usually covered; humidity and slab moisture are treated as building conditions and generally are not. Find your sublimit before filing.
Still deciding?
The inspection is free and the written assessment is yours to keep, including when it says nothing needs doing. See what the visit includes, what the work costs, or how to check a licence.

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.
