Commercial mold remediation in Miami offices and shops

EPA guidance for commercial buildings recommends limited containment with a single layer of polyethylene sheeting for 10 to 100 square feet of mold. Above 100 square feet, it recommends full containment with double sheeting and an airlock. We measure first so the containment fits the job instead of guessing.

Inside containment, air filtration keeps dust moving toward the filters and away from occupied rooms. That is what keeps the suite next door, the hallway and your staff out of the work.

• Under 10 sq ft: careful cleanup with local protection
• 10 to 100 sq ft: limited containment, single sheeting
• Over 100 sq ft: full containment, double sheeting, airlock

Demolition and bagging are the dustiest parts of the job, so we can schedule them before opening, after close or over a weekend. Once containment is up and air filtration is running, quieter work can often continue while the rest of the space stays open. We agree on the schedule before the first panel of sheeting goes up.

Restaurants, clinics and retail floors each have their own limits. We ask about deliveries, patient hours, inventory and anything else that affects when and where the crew can work.

Porous materials with mold growing into them, like drywall, ceiling tiles, insulation and carpet, are cut out and bagged inside containment. Hard surfaces such as metal studs, concrete and sealed wood are cleaned. The EPA says moldy surfaces should not be painted or caulked until they are cleaned and dry.

We photograph the area before, during and after removal. That record helps the property manager, the tenant and any insurer see what was taken out and why.

The EPA says cleaning mold without fixing the water problem usually lets it come back. In commercial buildings the usual causes are roof leaks, condensation on cold ducts, AC drain problems and slow plumbing leaks inside walls. We trace the moisture with meters and thermal imaging and tell you what needs repair.

Where the repair belongs to a plumber, roofer or HVAC contractor, we explain what we found so they can fix it before walls are closed. Drying equipment can run while that happens.

Florida keeps mold assessment and mold remediation separate on the same structure. A remediator cannot assess a building it remediated within the previous 12 months. So we never grade our own work: an independent assessor and lab check the space after we finish.

We coordinate timing with the assessor so containment stays up until results come back. If an area does not pass, we clean it again and the assessor checks it again.
