Black mold removal in Titusville, FL

What "black mold" usually means

"Black mold" is the everyday name for Stachybotrys chartarum, a dark green to black mold that grows on materials that stay wet for a long time, especially drywall paper, wood and ceiling tiles. It's often slimy when wet and sooty when dry.

Plenty of other molds also look dark, including Cladosporium and some Aspergillus species. You can't tell them apart by eye, and for removal purposes it doesn't matter much: any mold growing indoors needs to be removed and its moisture source fixed. What dark mold on drywall does tell you is that the material has been wet for days or weeks, not hours.

Where black mold grows in Titusville homes

• Behind and under bathroom vanities and toilets, from slow supply-line or wax-ring leaks.
• Lower drywall and baseboards on slab homes, where a hidden plumbing leak wicks up the wall.
• Under kitchen sinks and behind dishwashers and refrigerators with ice-maker lines.
• Ceilings and attic decking after roof leaks that weren't dried quickly after a storm.
• Around the AC air handler closet when the drain pan overflows or the condensate line backs up.
• Exterior walls and window frames where wind-driven rain gets behind stucco or past seals.

Is black mold dangerous?

Black mold can irritate the eyes, nose, throat and lungs, and it's a bigger concern for babies, older adults, and people with asthma, allergies or weakened immune systems. Mold of any color can cause these reactions in sensitive people. The practical advice is the same either way: don't live with it, don't disturb it yourself if it covers a large area, and talk to a doctor about any health symptoms.

How professional black mold removal works

1. Find and fix the water. The leak, drain line or humidity problem is found and repaired first. Otherwise the mold grows back.
2. Set up containment. The area is sealed with plastic sheeting, and air scrubbers create negative pressure so spores can't drift into the rest of the house.
3. Protect the workers and you. Technicians wear respirators and protective suits. Vents in the work area are covered and the AC may be shut off.
4. Remove contaminated materials. Moldy drywall is cut out at least a little beyond the visible growth, along with wet insulation, baseboards and carpet pad. Debris is bagged inside the containment.
5. Clean what stays. Studs, framing and hard surfaces are HEPA-vacuumed, scrubbed and wiped. Sanding may be used on lightly stained framing.
6. Dry the structure. Dehumidifiers and air movers bring moisture back to normal before anything is closed up.
7. Verify, then rebuild. A visual check and, ideally, clearance testing confirm the area is clean before new drywall goes in.

What not to do with black mold

• Don't just spray bleach. The EPA says bleach is not recommended as a routine practice during mold cleanup. It can lighten the stain on drywall while the growth inside the paper and the moisture behind it stay. Never mix bleach with ammonia cleaners.
• Don't paint over it. Paint traps moisture and the mold keeps growing underneath.
• Don't dry-brush or vacuum it with a regular vacuum. Both throw spores into the air and spread them through the house.
• Don't run the AC with mold in the air handler. It pushes spores to every room.

Can you remove it yourself?

The EPA's guidance is that a homeowner can usually handle mold covering less than about 10 square feet, roughly a 3 by 3 foot patch, on a hard surface, with gloves, goggles, an N95 respirator and good ventilation. Florida law also draws the line at 10 square feet: remediation of larger areas must be done by a licensed mold remediator.

Call a pro when the mold is on drywall, insulation or carpet, when it covers more than about 10 square feet, when it followed sewage or flood water, when it's inside the AC system, or when someone in the home is in a higher-risk group.

What black mold removal costs

Price depends on how much material has to come out and how much containment the job needs. A small bathroom job can run a few hundred dollars, while black mold that has spread through several walls or an attic can run into the thousands. See the mold removal cost guide for typical ranges, or the Titusville mold removal overview for how the full process fits together. If the mold followed a recent leak or storm, start with mold after water damage.
