His team (Dequan, David, Maurice and Randy) were so accommodating. I wish every contractor I hired worked this way. Thank you!"

"We recently worked with Flood Solutions after our basement flooded, and Megan—our inspector and project manager—was incredible. She was thorough, patient, and took the time to explain every step of the process, which meant a lot as an allergy sufferer worried about proper remediation. She honestly deserves her own show on mold education! When the team arrived, they were organized, detailed, and clearly cared about doing things the right way. Matthew and the crew also did a fantastic job finishing everything and making sure we felt informed and comfortable throughout. We can’t recommend Flood Solutions enough. If you need a trustworthy team during a stressful time, call them—and hopefully you get Megan, she’s a gem!"

We are a locally owned and family operated in Baltimore, MD. Our company has been in service since 2000 and we have over 35 years of collective experience in the industry. Our company is one of the few companies in the area that offers Particle Testing. We accept all insurances. Do not let the your insurance company tell you what remediation company you should use. It is your right to choose your own. We look forward to hearing from you.

"Thank you so much for a professional and efficient job! We had a flood in our basement and needed to have our carpet cleaned. Eco Pro cleaned the back of the carpet before it was put back in place. After the carpet was re-installed, they came back to do a complete cleaning of the entire basement carpeting. We put this carpeting in pretty recently, and Eco Pro saved us from needing to replace it. The carpet looks amazing and we are so happy to finally have our basement back!"

FAQs for mold & toxic material test projects in Gaithersburg, MD

Some companies offer a no‑cost phone or video consultation that screens for red flags. If the discussion points to a real issue, the pro will recommend a paid on‑site inspection. The complimentary call clarifies whether you need full testing, but it isn’t a substitute for samples, lab work, or a written report. Always confirm what the free service covers before you schedule.

A standard inspection, which includes basic air and surface samples, takes an average of two hours. If the pro needs to probe hidden spaces, such as wall cavities or ductwork, plan on up to six hours. Extra time allows the inspector to reach tight areas, collect additional samples, and document findings. Lab analysis is a separate process and often adds several business days to the overall timeframe before you receive the full report.

Mold thrives where moisture lingers and air flow is poor. Common hotspots include bathroom walls, kitchen backsplashes, window sills, HVAC vents, fireplaces, crawl spaces, and enclosed attics. Check these areas regularly—especially after leaks or high‑humidity weather—to catch growth early and avoid costly repairs.

Unchecked mold can knock 20% to 37% off a home’s market value because buyers worry about hidden damage and health risks. Even after remediation, visible staining or a history of major moisture issues can still lower offers and prolong the time on the market. Addressing mold quickly protects both your property’s structural integrity and its resale appeal.
