Mold Inspection in Martin County, FL (2025 Guide)

Here’s how to get reliable mold inspection in Martin County.

If you live in Stuart, Palm City, Jensen Beach, Hobe Sound, Indiantown, Port Salerno, or on Hutchinson Island, you know our climate is humid and storm‑prone. That means moisture problems happen. Mold can follow fast. A good inspection finds the source, documents damage, and gives you a clear plan to fix it.

This guide explains what to expect, when testing makes sense, and how to choose a qualified pro in Martin County.

Why Mold Inspections Matter

• Health risks: Mold can trigger allergies and asthma. Some people get coughing, wheezing, or sinus issues. People with weakened immune systems can be more sensitive. The EPA and CDC say the priority is moisture control and removal of moldy materials, not guessing the exact species.¹²
• Hidden damage: Small stains often mean bigger moisture issues inside walls, under floors, or in the HVAC system.
• Real estate: Buyers and sellers in Martin County often request mold inspections to avoid surprises at closing. A documented assessment and clear remediation plan can protect both sides.
• Insurance and storms: After wind‑driven rain or a roof leak, an inspection helps document cause and scope for claims.

Common Mold Issues in Martin County

Our local conditions create predictable patterns:

• Humidity and AC sizing: Oversized air conditioners cool quickly but do not dehumidify well. Indoor humidity creeps above 60%, and mold grows on vents, closets, and furniture.
• Wind‑driven rain: Stucco cracks, window frames, and sliding doors can leak in coastal storms.
• Roof and soffit leaks: Hurricanes and intense summer storms can open gaps that let water into attics and wall cavities.
• Slab and plumbing leaks: Slab-on-grade homes can hide leaks until flooring buckles or baseboards stain.
• Condensation: Cold supply ducts and metal air handlers sweat in hot garages and closets.
• Property types: CBS block homes, waterfront condos, and townhomes often show mold at exterior walls, around lanais, and in shared chases. Manufactured homes in western areas can have crawlspace moisture if skirting is not vented.

High‑risk rooms include bathrooms without proper exhaust to the outdoors, laundry rooms, and any closet with poor airflow.

How Mold Inspections Work

A thorough mold assessment focuses on moisture first. Most professional inspections include:

• Interview and history: Past leaks, musty odors, health complaints, insurance claims, and recent renovations.
• Visual inspection: Room by room, including attic, garage, and accessible crawlspaces.
• Moisture mapping: Pin and pinless moisture meters on walls, ceilings, and floors. Hygrometers for temperature, RH, and dew point.
• Thermal imaging: Used to spot hidden moisture, not as a standalone test.
• HVAC check: Supply/return balance, filter condition, drain pans, air handler cleanliness, and closet/attic conditions.
• Sampling (when indicated):
  • Surface tape lifts or swabs to confirm visible growth.
  • Air sampling (spore traps) for occupied areas, outdoors for baseline, and sometimes wall‑cavity air if hidden growth is suspected.
  • Dust sampling (ERMI/HERTSMI) can help some clients establish history, but it is not a regulatory test. Use judiciously.
• Laboratory analysis: Samples should go to an AIHA‑accredited lab with a clear chain of custody.
• Report and protocol: You should receive photos, moisture readings, a source‑of‑moisture diagnosis, and a remediation plan that aligns with industry standards (IICRC S520, ASTM D7338).³⁴⁵

Note: If you see visible mold and know the moisture source, the EPA says you usually do not need air testing. Fix the moisture and remove the damage safely.¹

Choosing a Certified Mold Inspector

Look for:

• Florida license: Mold Assessors must be licensed by the Florida Department of Business and Professional Regulation (DBPR). Ask for the license number and verify it online.⁶
• Relevant certifications: ACAC (CIEC/CMRS) or IICRC (AMRT/WRT) show training and ethics.⁴
• Standards‑based work: Inspector follows ASTM D7338 for assessment and references IICRC S520 for remediation planning.⁴⁵
• Insurance: General liability and professional liability (E&O).
• Independence: Avoid hiring the same company to assess and remediate the same project. It reduces conflicts of interest.
• Clear deliverables: Written report, moisture map, photos, and a step‑by‑step remediation protocol.
• Local experience: Ask about stucco leak diagnostics, coastal humidity issues, and HVAC moisture control in South Florida homes.

Mold Laws and Regulations in Florida

• Licensing: Florida requires licenses for Mold Assessors and Mold Remediators through DBPR. Always verify status and any complaints.⁶
• No state exposure limits: Florida, like the federal government, has no numerical “safe level” for mold. The goal is to remove growth and correct moisture.
• Real estate: Sellers must disclose known material defects, including water intrusion and mold conditions. Many use the Florida Realtors disclosure form.
• Landlord/tenant: Landlords must provide habitable housing. There is no specific statewide “mold law,” but leaks and moisture intrusion should be addressed promptly to prevent damage and health concerns.
• Guidance: EPA, CDC, HUD, and NIOSH offer national guidance used in Florida projects.¹²³

DIY vs. Professional Testing

DIY actions that help:

• Measure indoor humidity. Keep it near 40–50%.
• Run bath fans that vent outdoors for 20–30 minutes after showers.
• Maintain AC. Set to auto fan. Clean or replace filters. Keep setpoints realistic to avoid sweating ducts.
• Use a dehumidifier if RH stays high.
• Clean small surface mildew (under about 10 square feet) with detergent and water while you fix moisture. Wear gloves and an N95.

When to call a pro:

• Musty odors with no visible source.
• Recurring spots after cleaning.
• Water damage larger than a few square feet.
• After roof, plumbing, or storm events.
• Real estate transactions or insurance claims.
• Health sensitivities where documentation matters.

Avoid petri‑dish “mold kits.” They grow mold from the air but do not tell you if you have a building problem. They can be misleading and are not accepted for decisions by most pros or insurers.

What It Costs in Martin County

Prices vary by size and complexity:

• Condos and small homes: $350–$600
• Average single-family homes: $600–$1,200
• Large or complex homes: $1,200–$1,500+
• Samples (if needed): $45–$150 per sample, including report interpretation

Expect higher fees for after-hours emergency calls, multiple HVAC systems, or detailed remediation protocols.

After the Inspection: What You Should Get

• A moisture‑first diagnosis and cause (not just lab numbers)
• Clear photos and a moisture map
• A remediation protocol that aligns with IICRC S520, including:
  • Containment and negative pressure
  • PPE and safety
  • Removal of mold‑damaged porous materials
  • HEPA vacuuming and damp wiping
  • Drying and verification criteria
• Post‑remediation verification (PRV) options. This may include a visual check, moisture confirmation, and sometimes air or surface samples to confirm clearance.

Use separate companies for assessment, remediation, and PRV when possible.

Tips for Martin County Homes

• Seal and maintain stucco and window flashings. Address hairline cracks.
• Improve attic ventilation and check for wind‑driven rain points.
• Insulate cold ducts in warm spaces and fix disconnected returns.
• Keep closets ventilated. Avoid overpacked, closed closets in humid months.
• After storms, act fast. Dry within 24–48 hours to prevent mold growth.

Timeline

• Initial inspection: 1–2 hours for small homes; half‑day for large homes.
• Lab results: 1–3 business days (rush available).
• Remediation: 1–7+ days depending on scope.
• Clearance: Same day to 48 hours after remediation completion.

Next Steps

If you need a licensed Mold Assessor in Martin County, ask for DBPR license verification, sample deliverables, and a standards‑based protocol before you schedule.
