Guides & How To's

Whether you’re dealing with mold, poor ventilation, post-storm damage, or just trying to understand your home’s air quality, the right course of action depends on your specific situation — your property type, HOA rules, local regulations, and how complex the problem actually is. This resource helps you navigate those decisions with clear, practical guidance.

What Homeowners Can Reasonably Do Themselves

Some IAQ tasks are well within reach for most homeowners. Minor situations you can address on your own include:

Cleaning small patches of surface mold under 10 square feet (per EPA guidelines), using appropriate PPE and cleaning products such as detergent and water on non-porous surfaces
Replacing HVAC filters regularly — standard MERV-8 filters every 1–3 months, with higher-MERV filters per manufacturer specifications
Monitoring indoor humidity with a digital hygrometer and maintaining levels between 30–50% relative humidity
Installing or improving exhaust ventilation in bathrooms and kitchens, particularly in South Florida where humidity infiltration is a constant challenge
Adding weather stripping and door sweeps to reduce humid outdoor air infiltration
Running bath fans and kitchen exhaust during and after moisture-generating activities

These steps require no special licensing and can meaningfully improve your indoor air quality when done consistently. The EPA’s indoor air quality resources and the CDC’s NIOSH indoor environment guidance offer detailed guidance for homeowners.

When to Call a Qualified Contractor

Some IAQ situations require licensed professionals — either because the work is technically complex, potentially hazardous, or because local and HOA regulations require licensed contractors. Situations that warrant professional involvement include:

Mold beyond minor surface areas — anything larger than 10 sq ft, or any mold affecting HVAC systems, walls, or structural materials, should be handled by a licensed mold remediator. In Florida, mold remediation requires a state license under Florida Statute 468.84.
HVAC contamination — duct cleaning and HVAC-related mold remediation should be performed by contractors certified by the National Air Duct Cleaners Association (NADCA) or equivalent credentialing bodies. The American Industrial Hygiene Association (AIHA) provides guidance on industrial hygiene standards for indoor environments.
Post-flood remediation — water intrusion requires rapid professional response. Waiting more than 24–48 hours significantly increases mold risk in South Florida’s climate.
Structural moisture problems — leaking roofs, foundation moisture, or building envelope failures require licensed contractors and may require permits under the Florida Building Code.
Asbestos-containing materials — common in homes built before 1980. Any work disturbing these materials must be handled by a licensed asbestos abatement professional.

If your property is in an HOA, check your governing documents first — many HOAs require licensed contractors for any work affecting shared building systems, HVAC, roofing, or plumbing.

Understanding Your Situation

What’s appropriate for your specific situation depends on several factors that vary widely across South Florida properties:

HOA bylaws — condominium and HOA rules frequently restrict or prohibit DIY work on HVAC, roofing, plumbing, or other shared building systems. Violating these rules can create liability. Always review your governing documents and confirm with your association before beginning any work.
Rural vs. urban properties — rural areas may have less rigorous code enforcement, but contractor availability may also be more limited. Urban South Florida properties, particularly Miami-Dade and Broward, are subject to stricter inspection requirements under the Florida Building Code.
Rental vs. owned — if you’re a tenant, remediation and repair responsibility typically rests with the landlord. Document problems in writing. Landlords in Florida are required to maintain habitable conditions under Florida Statute 83.51.
Condo vs. single-family — condominiums have shared envelope, roof, and HVAC systems. Responsibility boundaries between unit owner and the association vary significantly by building and governing documents.
Age of home — homes built before 1980 may contain asbestos insulation, floor tiles, or pipe wrap, and homes built before 1978 may contain lead paint, adding complexity to any renovation or remediation work.
