Crawl Space Mold Removal in Metairie, LA
Crawl space mold removal in Metairie is for raised houses where the trouble is under the floor: white or dark growth on the joists, a subfloor that reads damp, insulation sagging out of the bays, or a musty smell that is strongest in the rooms nearest the floor. An independent inspector gets under the house first and records what the moisture is doing; a separate remediation contractor then cleans and treats the framing and deals with the ground cover so the air down there stops feeding growth. Call (504) 360-1797 to have the crawl space looked at.
Crawl space mold removal in Metairie: what it involves
The structure under a raised floor is mostly wood: sill plates, beams, joists and the underside of the subfloor. Growth on those members is cleaned and treated in place rather than replaced, unless the wood has softened. Fiberglass batts that have taken on moisture usually come out, because they hold water against the wood they were meant to protect. The ground is then covered so damp soil is no longer open to the framing above it.
Why crawl space mold grows under Metairie houses
Summer air here carries a lot of water. At the NOAA station in Kenner the average dew point is above 70°F from June through September and around 74°F in July and August. When that air drifts through foundation vents and meets joists cooled by the air-conditioned rooms above, moisture condenses on the wood, and condensation is enough for mold.
The ground adds to it. Tulane geographer Richard Campanella has written that the drained former backswamps of Metairie lie 6 to 8 feet below sea level, and as much as 12 feet in parts. That drained land settled unevenly, he notes, and NASA's 2009-2012 radar study observed notable subsidence in Metairie, which is why the inspection also looks at the piers, the plumbing runs and the openings around them.
How crawl space mold removal is carried out
Inspection. Moisture readings on joists and subfloor, a look at the vents, plumbing and ground, and a written scope.
Protecting the rooms above. Floor penetrations such as registers and pipe openings are sealed so work below does not push spores into the living space.
Removal and cleaning. Wet or contaminated insulation and debris come out in bags; the framing is HEPA-vacuumed, cleaned by scraping, sanding or media blasting as needed, and treated.
Ground cover. A vapor barrier goes down over the soil, or the whole space is encapsulated, depending on what the scope calls for.
Confirmation. Moisture readings are taken again, and the independent side can check the result.
Vapor barrier or encapsulation for a crawl space
A vapor barrier is a sheet of polyethylene laid over the ground, overlapped and held down, which stops soil moisture rising into the space. Encapsulation goes further: heavier liner up the walls and piers, vents closed, and the space dried with a dehumidifier or conditioned air, so the crawl space behaves like part of the house. Which one fits depends on how wet the ground gets, the state of the vents and how the house is used, and the written scope should explain the choice.
Crawl space mold and the Louisiana two-company rule
Louisiana law (La. R.S. 37:2158(A)(23)(c)-(d)) does not let one mold remediation contractor both assess and remediate the same property, or own a stake in both businesses. So the person crawling under your floor to write the scope is not the person paid to carry it out, and a finished crawl space can be checked by the independent side before the job is signed off.
Crawl space mold removal cost
Cleaning and treating a crawl space under a raised house is $3,000 to $12,000 in the published price table; access height, the floor area, how much insulation comes out and whether the job ends with a vapor barrier or full encapsulation move it within that range. The inspection beforehand is $300 to $650, plus $75 to $150 for crawl space entry.
That is a range for planning, not a quote: the number for your house follows the inspection and is put in writing. See the mold removal cost page for the whole table.
Arranging a crawl space inspection in Metairie
Call (504) 360-1797 and mention how you get under the house (hatch, skirting panel or open piers), what you have noticed in the rooms above, and whether the space ever holds standing water. If writing suits you better, use the callback form below or the contact page.
Crawl space mold questions
What should I do about mold in my crawl space?
Have it inspected before anything is sprayed or covered: the inspector measures how wet the framing is, how far growth has spread and where the moisture comes from, and that sets the scope for the separate remediation contractor. To book a crawl space inspection in Metairie, call (504) 360-1797.
Can black mold be removed from wood?
Under a house it nearly always is: joists, beams and subfloor are HEPA-vacuumed, cleaned by sanding or blasting where needed, and treated, and only softened wood is replaced. The ground cover then stops the moisture that grew it. Ask about your crawl space framing on (504) 360-1797.
What is the average cost to remove mold?
For a crawl space under a raised Metairie house the published range is $3,000 to $12,000, with the inspection at $300 to $650 plus $75 to $150 for crawl space entry. Smaller jobs elsewhere in a house start at $600. For a written figure on your crawl space, call (504) 360-1797.
Is a mold inspection worth it?
Under a house it usually is, because the space is hard to see into and the inspector's moisture readings decide between a vapor barrier, encapsulation or more. It also keeps the scope independent of the company doing the work. Book a crawl space inspection on (504) 360-1797.
Can a house with mold be saved?
Crawl space mold rarely means losing the house: the framing is cleaned and treated, damaged insulation is replaced, and the ground is covered so the problem does not return. Softened wood is the exception and is repaired. To find out what your crawl space needs, call (504) 360-1797.
Should I pay for mold remediation?
If growth is on the joists or subfloor, cleaning and treating it and covering the soil is what stops it from coming back, so it is money that addresses the cause. If the inspection finds only surface moisture, the scope may be smaller. Find out which on (504) 360-1797.
