Attic and crawl space mold in Vero Beach and Indian River County
Dark spots on attic wood or a musty crawl space in Vero Beach, FL? Get matched with a state licensed mold professional to inspect and clean it up.
Attics and crawl spaces are out of sight, so problems there can go on for years before anyone notices. In Florida, a hot attic can still be a damp one. Warm, moist air rises from the living space, meets cooler surfaces such as the underside of the roof deck or an air duct, and the water that condenses can feed mold.
Common causes in attics
- Roof leaks. A slow leak around a vent pipe, flashing or damaged shingle or tile can wet the decking and insulation for a long time.
- Bathroom or kitchen fans that vent into the attic. Fans should be ducted to the outside. A fan that ends in the attic dumps moist air right where you do not want it.
- Poor ventilation. Soffit and ridge vents that are blocked or missing can trap humid air.
- Air conditioning ducts and air handlers. Cold ducts in a hot attic can sweat, especially if insulation is torn or poorly sealed.
Crawl spaces on the Treasure Coast
Most homes here are built on a concrete slab, so crawl spaces are less common than in other parts of the country. You still find them under older raised homes, additions and some island and lagoon front houses. A crawl space gets damp from soil moisture, poor ventilation, plumbing leaks and rain that runs in. Ground water in this area tends to be high, so crawl spaces can be damp more often than people expect.
Not every dark spot is active mold
Roof decking can darken from age, from old moisture that dried, or from staining that is not growing today. A licensed assessor can tell the difference with moisture readings and, if needed, samples. It is better to find out what is going on before paying for cleanup, and just as important to know when a stain is only old discoloration.
What a fix often involves
The order of work usually goes like this. First, find and fix the moisture source, such as a leak, a fan duct or a ventilation problem. Then a licensed remediator cleans or removes what is affected, which can mean cleaning framing and decking and replacing wet insulation. Finally, a follow up check confirms the area is dry. Roof repairs are a separate trade, and a mold professional will usually tell you when you need a roofer first.
Licensed professionals
Florida licenses mold assessors and mold remediators separately through the Department of Business and Professional Regulation. As a general rule, the company that assesses a building should not remediate it within the next 12 months, which keeps the person who finds the problem apart from the person who sells the fix. Read how we handle that.
What it costs
Attic jobs vary with the square footage, the amount of insulation to replace and how accessible the space is. Small spots can be a modest job, while a full attic can cost several thousand dollars or more. Quotes should list exactly what is being cleaned, removed and replaced.
Next steps: get an inspection to confirm what you have, or read about AC and ductwork mold concerns if the air handler is in your attic.
Common questions
Can I look in my own attic?
You can peek with a flashlight from the access hatch, but attics in Florida get very hot and have exposed nails, wiring and weak spots in the ceiling. Do not step between joists unless you know where it is safe. A professional can do this safely.
What is a normal attic humidity?
There is no single number for every home, but the EPA suggests keeping indoor humidity below 60 percent, and ideally between 30 and 50 percent. Attics are not conditioned like living space, so a professional can tell you what the readings mean.
