Baltimore's rowhomes were built to last, but a hundred years of rain, rising groundwater, and shared walls give mold plenty of places to start. MoldGone is based just down the road in Columbia, and we handle Baltimore mold problems from the source of the moisture to the finished rebuild.
MoldGone is a Maryland company, headquartered in Columbia and working in Baltimore homes since 2006. Most remediation jobs in this city involve more than mold. There's a damp cellar, an old roof, or a wall that's been wet for years. We treat the mold, correct the moisture problem that caused it, and do the demolition and reconstruction ourselves.
We're fully licensed in Maryland, Virginia, and D.C., with bonding and insurance that protect you through every stage of the work.
We've completed thousands of projects across Baltimore, the surrounding counties, and the rest of the DMV. Our clients consistently point to our thoroughness and follow-through.
Every MoldGone technician holds IICRC certifications and has construction experience. In Baltimore, where remediation often means working with plaster walls, stone foundations, and hundred-year-old framing, that combination matters.
MoldGone holds an A+ rating from the Better Business Bureau, an Angi Super Service Award, and five-star reviews across Google, Yelp, and Angi.
We walk you through the scope, explain each step, and answer questions in plain language. You'll know the plan and the price before we start.
Our crew handles carpentry, drywall and plaster, painting, flooring, electrical, and plumbing. When the remediation is done, the same team puts your home back together.
Baltimore has one of the largest concentrations of rowhomes in the country, and many of them date to the late 1800s and early 1900s. Cellars with fieldstone or brick foundations were never designed to stay dry, and when they're finished into living space, water that used to evaporate off the walls gets trapped behind drywall instead. Shared party walls mean a neighbor's roof leak or wet basement can become your problem, and flat roofs on rear additions in Canton, Federal Hill, Hampden, and Highlandtown leak at the flashing for a long time before anyone notices.
Location plays a role too. Neighborhoods close to the harbor, like Fells Point and parts of Canton and Locust Point, sit low and have seen tidal and storm flooding. The city's aging sewer system can back up into basements during heavy rain, which brings contaminated water into the lowest level of the house. And Baltimore's humid summers keep damp basements damp for months at a time.
Farther out, Baltimore County homes in Towson, Catonsville, Parkville, and Pikesville deal with their own version of the problem: finished basements, split-levels with below-grade family rooms, and older colonials with aging plumbing and gutters that push water toward the foundation.
Mold takes hold wherever water sits: after a pipe leak, a basement backup, a roof failure, or a humid summer in a cellar with no airflow. Remediation brings mold back to normal background levels, known in the industry as "normal fungal ecology." It means identifying why mold is growing, keeping it from spreading while the work is done, removing contaminated materials, and making the space healthy to be in again.
In a Baltimore rowhome, the "why" usually matters as much as the mold. If the cellar wall is still wicking water or the rear roof is still leaking, the mold will come back. We find the moisture source and deal with it as part of the job.

We start with an in-person consultation at your property. From there, our team writes a customized remediation protocol that lays out the treatment methods, materials, and pricing before any work begins.
If your mold is connected to a covered water event, we document the damage and communicate with your adjuster to keep your claim on track.
We seal off the work area and run HEPA air filtration during removal. In rowhomes, where floors connect through shared stairwells and ductwork, containment keeps the rest of the house clean.
Contaminated drywall, insulation, and carpet are removed, and framing and masonry are cleaned and treated with antimicrobials. We also track down the moisture source, whether it's a cellar wall, a rear roof, or a plumbing line.
When the area is clear, we rebuild it to pre-damage condition, including drywall, plaster repair, trim, painting, tile, and flooring.
We work throughout Baltimore City and Baltimore County. Don't see your neighborhood? We also serve Howard and Anne Arundel counties.

It can be. Mold exposure commonly causes allergy symptoms like sneezing, congestion, and itchy eyes, and it can make asthma worse. Children, older adults, and people with weakened immune systems or lung conditions are more sensitive. And because air from a basement moves up through the rest of the house, a moldy cellar affects the whole home.
Many older Baltimore basements were never meant to be fully dry, so some dampness is common. But a musty smell, visible growth, white mineral deposits on the walls, or water lines after storms are signs the moisture has crossed into a problem. If the space is finished or used for storage, it's worth having it looked at.
Small spots on non-porous surfaces like tile or glass can usually be cleaned. But mold on drywall, wood, or plaster often extends well beyond what's visible, and DIY cleanup rarely addresses the moisture behind it. A professional evaluation will tell you how big the problem really is.
If you know you have mold, we can typically schedule a consultation within 1 to 2 business days and start remediation within 3 business days of that visit. The overall length depends on how much material needs to be removed and rebuilt. You'll have a clear timeline before work starts.
Sometimes. Some mold problems can be handled with surface cleaning and treatment, while others require removing and rebuilding affected sections. Since we do both remediation and reconstruction, we'll recommend what the situation actually calls for.
Photos are useful for context, but they can't show what's inside walls or in the air. We need to see the property in person to give you an accurate evaluation and price.
If we don't find visible mold during an inspection, we may collect samples and recommend independent third-party lab analysis. It adds cost and usually takes 3 to 5 business days, so if mold is clearly visible, it's often not necessary. We'll advise you on what makes sense for your situation.
Our reputation is built on results. Here's what our clients have to say about their experience with MoldGone.
They arrived exactly on time, and were extremely professional and knowledgeable. They conducted the inspection thoroughly but in a time efficient manner, and were straightforward in describing each step and what their results were.
He easily could have recommended a full (and expensive) remediation project of our entire kitchen flooring, but gave us an honest answer that likely saved us thousands of dollars at this time - while being realistic we may need to do so in the future.
During our inspection, he took the time to answer all of our questions. He's very knowledgeable and pleasant!
