24/7 emergency response, certified technicians, and clear insurance documentation support — from first call to final restoration.
Mold is more than a cosmetic problem. In Central Maryland's humid summers and damp basements, mold can take hold within 24 to 48 hours of a water leak or flood, spreading behind drywall, under flooring, and through HVAC systems where you can't see it. Left unaddressed, it damages building materials and can aggravate allergies, asthma, and other respiratory conditions for everyone in the home. The key to a lasting fix is finding and correcting the moisture source, not just wiping away what's visible on the surface.
Clean Sweep Enterprises has been a woman-owned, IICRC-certified restoration company serving Central Maryland since 1991. Our certified technicians follow the IICRC S520 standard for professional mold remediation: we inspect the property and test air quality, contain the affected area to prevent cross-contamination, remove mold-damaged materials, apply antimicrobial treatment, and confirm the work with post-remediation clearance testing. Because mold almost always traces back to a water problem, we also identify and help resolve the underlying source so it doesn't come back.
We answer the phone 24/7, because the longer mold sits, the further it spreads and the more it costs to remove. We also coordinate directly with your insurance carrier, document the loss with photos and moisture readings, and work from a clear written scope so you understand exactly what the restoration includes and what to expect. Our goal is a healthy, properly dried home and the verification to prove it.

Frequently Asked Questions
Don't disturb it — scrubbing or wiping large patches can release spores and spread them through the air. Stop the water source if you can (shut off a leaking valve, run a dehumidifier), keep people and pets away from the area, and turn off the HVAC if mold is near a vent or return so spores aren't circulated. Then call us at any hour for an inspection. Avoid bleach-and-paint cover-ups; they hide the problem without removing it.
It depends on the cause. Most policies cover mold when it results from a sudden, covered event — like a burst pipe or an overflow you addressed promptly. Mold from long-term neglect, deferred maintenance, or flooding (which needs separate flood insurance) is often excluded, and many Maryland policies cap mold coverage at a set dollar amount. We document the loss thoroughly and coordinate directly with your adjuster on the restoration scope, and we recommend confirming what your policy covers with your carrier.
Most residential projects take 3 to 7 days. Small surface jobs can be done in a day or two, while larger or hidden infestations that require containment, demolition, drying, and clearance testing take longer. Drying time depends on how saturated the materials are. If reconstruction (new drywall, flooring, or paint) is needed afterward, that's performed by your chosen rebuild contractor once clearance testing has verified the space is clean and dry.
The EPA's general guideline is that homeowners can clean mold on hard surfaces covering less than about 10 square feet. Beyond that, or any time mold is inside walls, in a crawlspace, in your HVAC system, or tied to sewage or flood water, you need professional containment and air filtration to remove it safely without spreading spores. If anyone in the home has asthma, allergies, or a weakened immune system, professional handling is the safer choice.
Yes. We perform a visual inspection with moisture meters and can take air and surface samples sent to an independent lab. After remediation, we conduct post-remediation clearance testing to verify the spore counts are back to normal background levels. Using a third-party lab for clearance keeps the verification objective and gives you documented proof the work was effective.
Mold returns when moisture returns, so the lasting fix is controlling humidity and stopping leaks. In Central Maryland that usually means keeping indoor humidity below about 50% (a dehumidifier helps in basements and crawlspaces), fixing roof and plumbing leaks quickly, making sure bathroom fans and the dryer vent to the outside, and improving ventilation. As part of our work we identify and help you address the original water source so the conditions that grew the mold don't simply recreate it.
