"The team from Stay Dry was very professional. They were informative and transparent when describing what the work would entail and sent me pictures and updates throughout the day. They went out of their way to provide a thorough service. It is hard to know who to trust when having mold remediated because the levels of training and expertise are very different across companies. They are skilled and they care about the quality of their work and customer service. I will hire them again for the next project."

Traditional mold remediation techniques date back to the 1980s. While they’re sometimes necessary for severely damaged surfaces, they often fall short—failing to eliminate airborne spores that spread mold throughout your home. More spores means more surfaces… and more mold.\n\nThat’s where we come in. Our patented, demolition-free dry-fogging process is scientifically proven to eliminate mold—not just from surfaces, but from the air itself—in just a few hours. No mess. No stress. No reconstruction. \n\nIt’s faster, safer, and far more affordable than any other mold solution in Columbus. You get peace of mind, a healthier home, and your life back—without the nightmare.

"The only contractor where the owner does the estimate and is onsite for the whole job. I was impressed that the crew showed up on time and finished early. Even got to use the roll off to clean out my garage. It sucks getting mold, but if I ever get it again, I'll be giving Sherlock Homes a call."

"I just put a brand new roof on my home and i called a security first inspection to come out and make sure it was done properly and he found major issues with the ventilation the roofers put on so it was worth my money to call someone out that did identify problems and i got it straightened out before it caused an issuea,"

Mold Testing and Remediation FAQs, answered by experts

A funky smell is the first indicator that mold or mildew is present in your home. You may also notice that you or your household members are suffering from increased allergies or respiratory issues. You should check the most obvious areas first—like your bathroom or anywhere there might be leaks—and if you still can’t locate the source, look under the floorboards. 

Mildew is a type of mold that forms in areas of excessive moisture and poor ventilation. Although it commonly exists in household air, it can’t take hold and spread if a surface is clean and dry. Generally, if you have any mildew or mold issues, it’s because the humidity in either your house, room, cabinet, or cupboard is above 50 percent. Common areas where you’ll find mildew are around water sources, which is why it’s commonly found near showers and in kitchen sinks.

It’s possible that installing solar panels can lead to mold on the roof. The panels themselves are not the issue. Problems caused by improper installation—such as roof leaks and mounts that aren’t sealed properly—can cause mold. Another potential cause of mold is debris accumulation under panels, which can trap moisture. If you live somewhere with extreme snow, rain, or hail, your home could be more prone to mold.

You can check your home's humidity in a few ways. A simple option is to use a hygrometer, which you can find at a hardware or big box store. Your smartphone may also have an app that can measure humidity. Modern thermostats, particularly smart thermostats, are also able to measure humidity levels.

Mold doesn’t take long to form, especially in dark, isolated areas like under the floorboards, where you’re less likely to know it’s wet in the first place. Mold can take root and proliferate in just 24 to 48 hours, but it can be up to a week before you start to notice funky smells.
