"I had a great experience with American Dry Basements. From start to finish, their team was professional, knowledgeable, and easy to work with. They took the time to explain everything clearly and made sure the job was done right the first time. What really stood out to me was their fair and affordable pricing—no surprises, just honest work at a reasonable cost. It’s not always easy to find a company that combines quality service with good value, but they definitely delivered on both. If you’re looking for reliable basement waterproofing with a team you can trust, I highly recommend giving them a call."

"He was on time, friendly, and honest. We had a plumber tell us that the pipe was broken at the septic tank so Phil and Mike came out to dig it up and replace it. When he dug it up he found that the pipe was not broken and was totally honest about it and gave us options and help that solved our issue we were having. I would totally use him again for any work I need done in the future."

Basement Waterproofing questions, answered by experts

It depends on what caused your basement flooding, the extent of the problem, and the risk of the flood continuing. If your flood is coming from a septic system or sewer line, breathing in the sewer gasses can be dangerous, so you should vacate. If the flood occurs from an ongoing natural disaster, relocating to a safe area might be wise. If you just have a plumbing leak or rainwater coming in, you can likely stay in the house if you don’t have electrical lines down there, but make sure you call in professionals to fix the issue immediately.

Yes, it is possible to over-dehumidify a house by removing too much moisture from the air. This can create an overly dry environment that negatively affects those with respiratory or skin issues, and may cause your skin, hair, and sinuses to feel dry. However, this is unlikely to happen with most modern dehumidifiers, as they are equipped with moisture sensors and adjustable settings. These features allow the unit to pause automatically when the desired humidity level is reached, preventing the air from becoming uncomfortably dry. In contrast, older or more basic dehumidifiers left running for too long could potentially over-dry the air. To avoid this, aim for a balance between removing excess moisture and maintaining a comfortable environment. You can often monitor your home's humidity levels using a modern thermostat for guidance.

Yes, crawl spaces can attract bugs, especially since moisture tends to build up in the space, and moisture attracts pests. A good way to prevent pest infestation in your crawl space is to install a vapor barrier—called crawl space encapsulation—on the interior to seal the space, along with a French drain or some other kind of foundation drainage system outside to keep runoff out of your crawl space. You can also seal foundation cracks and repair damages to cut off access to pests.

Living in a finished basement is acceptable, but only if the space has the proper points of egress and includes smoke and carbon monoxide (CO) detectors to ensure the safety of the occupants. A good way to ensure your finished basement is suitable for use as living space is to get the basement finishing project properly permitted.

Walkout basements cost more than other kinds of basements, and can also increase your risk of leaks as well as a loss of insulation, leading to higher heating and cooling costs. Improperly installed walkout basements may lead to structural issues with your foundation, so ensure you’re working with a contractor who has extensive experience with this kind of basement.
