Buying a home in Louisiana comes with a lot of inspection decisions. Here's specifically when to add a mould-specialised inspection, what it costs, and how to use the report in the transaction.
Should you get a mould inspection when buying a Louisiana home?
In Louisiana's very high-humidity climate, the answer is almost always yes -- especially for any home older than 30 years, any home with a basement or crawl space, or any home with visible signs of past water damage. The cost ($300-$700) is trivial compared to discovering remediation needs after closing.
Specific scenarios that justify a pre-purchase mould inspection regardless of state:
- Visible water staining on ceilings, walls, or in basements
- A musty or earthy smell anywhere in the home
- History of flooding, sustained leaks, or insurance claims (ask the seller)
- Vented crawl space, unfinished basement, or flat roof
- HVAC system that's overdue for service or has visible condensate problems
- Any disclosure of prior mould remediation -- you want post-remediation verification
How a pre-purchase mould inspection differs from a general home inspection
A general home inspector covers mould as one of many systems -- a brief visual check, no specialised tools, often no separate report. A mould-specialised inspection adds:
- •Visual walk-through of all systems
- •Brief mould check (visible growth, obvious water damage)
- •No moisture meter readings (typically)
- •No thermal imaging (typically)
- •No lab samples
- •Mould findings reported as one item among many
- •Focused mould assessment
- •Moisture meter readings on all suspect surfaces
- •Thermal imaging to find hidden cold (wet) spots
- •Optional air or surface samples to lab
- •Detailed photographic documentation
- •Standalone report you can use for negotiation, insurance, etc.
If the general inspection flags any mould or moisture concerns, escalating to a mould-specialised inspection is almost always worth it before closing.
Timing the inspection in a Louisiana transaction
Louisiana real-estate transactions follow standard practices, but timing the mould inspection matters:
- Schedule the mould inspection during your inspection contingency period (typically 7-14 days from contract).
- If lab samples are involved, allow 5-10 business days for results -- start IMMEDIATELY after general home inspection results come in.
- Use the report to negotiate: repair credits, price reduction, seller-paid remediation pre-closing, or escrow holdback.
- If significant remediation is needed, consider extending the contingency or moving to remediate-then-close with post-remediation verification.
Sellers sometimes provide a previous mould inspection or "clearance" report. These are useful as background, but you should always commission your own inspection -- conditions change, reports may be incomplete, and the seller's inspector wasn't representing your interests.
Louisiana licensing requirements
Because Louisiana requires state licensure for mold assessors, your pre-purchase inspector should hold an active Louisiana State Licensing Board for Contractors licence. This matters for two reasons:
- Insurance carriers and lenders may require licensed-assessor reports for any post-purchase claim or financing condition.
- Real-estate disclosure laws and seller obligations may differ when licensed vs. unlicensed reports are involved.
- If post-remediation verification is part of the deal, the verifying inspector also needs to be licensed (and ideally separate from any remediator).
Tip: Ask the inspector for their Louisiana licence number and verify it at https://lslbc.louisiana.gov/ before paying. A 30-second verification can save weeks of trouble.
What to do with the report
Once you have the inspection report, the typical paths in a transaction:
- Findings are clean -- proceed to closing with confidence and a documented baseline.
- Minor findings -- ask the seller for repair credits or to address before closing.
- Significant findings -- negotiate price reduction, seller-paid remediation, or walk away.
- Findings affect insurability or financing -- pause and resolve before continuing.
Your real-estate agent can help structure the negotiation, but the inspector should NOT be involved in deal-making. Their report stands alone.
Post-purchase: what to do in the first 90 days
Even with a clean inspection, Louisiana buyers should establish a baseline in the first 90 days of ownership:
- Buy a $10 hygrometer and measure indoor RH in different rooms over a couple of weeks
- Service the HVAC system (clean condensate path, change filters, check ductwork)
- Inspect attic and any crawl spaces / basements for any signs you missed
- Address any noted maintenance items from the inspection promptly -- waiting often turns small problems into big ones
- Set up dehumidification if humidity is above 60% during summer months
