What Indoor Air Quality Testing Actually Measures
A real indoor air quality test measures eight core parameters: indoor temperature, relative humidity, fine particulate (PM2.5), carbon dioxide (CO₂), carbon monoxide (CO), combustible gas, formaldehyde, and total volatile organic compounds (TVOCs). Together they describe how the building is performing and whether occupants are being exposed to something they should not be.

Mold Inspection vs Mold Testing: What's the Difference?
A mold inspection is a building-science investigation: it finds the moisture source, the affected materials and the likely extent. Mold testing is laboratory analysis of air or surface samples. Inspection is almost always required; testing is only useful when it can answer a specific question that inspection alone cannot.

Florida Mold Remediation Standards: S520, Containment & PRV
Mold remediation in the United States follows ANSI/IICRC S520 — the standard of care for cleaning mold-contaminated materials. It defines condition classes, containment levels, engineering controls and verification criteria. Florida law adds a separation rule: the assessor who writes the protocol cannot be the contractor who executes it.

Indoor Asthma and Allergen Triggers: What to Test For
Most indoor asthma and allergy symptoms trace to a small set of allergens — dust mite (Der p 1, Der f 1), cat (Fel d 1), dog (Can f 1), cockroach (Bla g 1/2), mouse (Mus m 1) and mold. Laboratory analysis of settled-dust samples quantifies which reservoirs in your home are actually driving symptoms.

When Spray Foam Goes Wrong in Florida
When spray polyurethane foam fails in a Florida home, it is almost always one of four causes: off-ratio mix at the gun, lifts applied too thick, an unvented attic that traps the off-gassing, or a pre-existing IAQ problem misattributed to the foam. Each has a different remedy.

Florida Asbestos & Lead Rules Before You Renovate
Florida and federal rules require a written asbestos survey before any demolition and before most renovations that disturb suspect materials in pre-1981 buildings. The EPA Renovation, Repair and Painting (RRP) rule adds lead-safe work practices for any project disturbing painted surfaces in pre-1978 housing or child-occupied facilities.
