Mold remediation after water damage
Mold remediation contains the affected area, removes moldy porous materials, cleans hard surfaces and fixes the moisture problem that caused it. Killing mold with a spray without removing it and drying the area doesn't solve the problem.

Mold needs moisture, food (drywall paper, wood, dust) and time. After a water loss that wasn't dried quickly, it can appear within days. The EPA suggests that areas larger than about 10 square feet are best handled by trained professionals.
A proper job sets up containment with plastic sheeting and negative air pressure so spores don't spread, removes affected drywall and insulation, HEPA-vacuums and cleans the framing, then dries everything. See how fast mold grows after water damage.
Mold remediation services cover residential mold, crawl space mold and black mold removal. The cost of mold remediation depends mostly on how large the affected area is and where it is, which is why companies inspect before they quote.

FAQ
Mold Remediation questions
Does bleach kill mold?
Bleach can whiten mold on hard, non-porous surfaces but doesn't reach roots in drywall or wood. Removal and drying are what solve it.
Do I need a mold test?
If mold is visible, testing usually isn't needed to decide on removal. Testing is useful after cleanup or when you smell mold but can't find it.
Will mold come back?
Not if the moisture source is fixed and materials are dried. Mold returns when leaks or high humidity continue.
How much does mold remediation cost?
It varies widely with the size and location of the growth, how much material must be removed and whether containment is needed. A small, accessible area costs far less than mold in walls, an attic, a crawl space or HVAC ducts. Get a written scope before work starts.
What is the difference between mold removal and mold remediation?
Mold removal usually means cleaning off visible growth. Mold remediation is the full process: containment, removing affected materials, cleaning, drying and fixing the moisture problem so it doesn't come back.
