Crawl Space Mold Removal in Lafayette, LA

Soft floors, a musty smell after a rain, white fuzz on the joists under the house — your crawl space is telling you something. Crawl spaces under Lafayette homes stay damp and dark, which is exactly what mold likes. One call to (337) 205-7937 connects you with a local pro who can look under the house, find where the moisture is coming from, and give you a free, no-pressure quote.

Signs of mold in your crawl space

You usually notice it from inside the house first:

• A musty, earthy smell that gets stronger on humid days or when the AC kicks on.
• Soft, bouncy or cupping floors. Wood that stays damp swells and weakens.
• Visible growth on joists or subfloor: white and cottony, green, or black and speckled.
• Sagging or wet insulation between the floor joists.
• Sweating ductwork, standing water, or a torn vapor barrier under the house.
• Allergies that flare up at home and ease when you leave.

Why crawl space mold is so common around Lafayette

Acadiana is wet. Lafayette Regional Airport averages 62.81 inches of rain a year (NOAA 1991–2020 normals), and the Gulf keeps the air humid most months. A crawl space sits between that damp ground and your cool, air-conditioned floor, so moisture condenses on the wood.

Lafayette also drains through a web of coulees and bayous (Coulee Mine, the Isaac Verot Coulee, Bayou Carencro and more) into the Vermilion River. In August 2016, days of heavy rain pushed the Vermilion to a 17.62-foot crest at Surrey Street, its second-highest on record, and floodwater reached nearly 2,000 homes in Lafayette Parish. Crawl spaces that took water then, or in any smaller flood since, can hold wet soil and damp framing long after the house upstairs looks fine.

Common causes your local pro will check:

• Ground moisture rising into the joists, especially with a missing or torn vapor barrier
• Gutters or yard grading that send rainwater under the house
• Plumbing leaks from supply lines, drains or a water heater
• AC ducts and lines sweating in humid air

What crawl space mold removal looks like

1. Call. Describe what you're seeing and set up a visit with your local pro.
2. Walkthrough and written quote. Your local pro goes under the house, checks how far the growth reaches, and tracks down the moisture source. You get a clear written quote before any work starts.
3. Containment. Access points are sealed off so spores don't get pulled into the living space.
4. Removal and cleaning. Moldy insulation and debris come out, and joists, beams and subfloor are cleaned. The exact method depends on the pro and the damage.
5. Fix the moisture. That can mean repairing a leak, replacing the vapor barrier, improving drainage, adding a dehumidifier or, if the pro offers it, encapsulating the crawl space.

As the EPA puts it, the key to mold control is moisture control. Killing what you can see without fixing the water only buys time.

What affects the cost

Crawl space jobs vary too much to price on a web page. The cost depends on:

• How much area is affected: a few joists near a leak, or the whole underside of the house.
• Access: low clearance and ductwork in the way add labor.
• What has to come out: wet insulation, old vapor barrier and debris.
• Damaged wood that may need repair.
• The moisture fix: vapor barrier, drainage, dehumidifier or encapsulation.

The walkthrough and quote are free, so you'll know the price before any work begins.

Serving Lafayette and Acadiana

Your local pro works on homes across Lafayette Parish and nearby, including Broussard, Youngsville, Scott, Carencro, Breaux Bridge, New Iberia and Abbeville. If your house sits near a coulee, took water in 2016, or has that "under the house" smell every summer, it's worth a look.

A note on testing: Louisiana licenses mold assessment separately from remediation, and one company can't do both on the same property. If you want testing, an independent licensed assessor can do it. Your local pro handles the removal.
