"They completed it in 2 days and I havent had an issue since the basement was waterproofed. However, they did forget to plan the initial inspection prior to the work as part of the permit. The city I live in ended up reaching out near the end of the permit date and I didnt know about it until then. I reached out to the project manager for my project at Acculevel about it and they did handle that issue promptly."

We deliver quality projects on time and within budget because we have genuinely care and concern for our customers. About the owners: Levi Bechtum has been in the construction industry for the past 12 years. His primary focus has been in remodel construction, excavation and plumbing. Born and raised in La Crosse, Levi attended and graduated from the University of Wisconsin La Crosse where he majored in Accounting and Finance. Levi lives in La Crosse with his wife and two kids. During his free time, Levi enjoys taking his family camping, buying reduced and damaged produce at the grocery store, creating small batches of charcuterie with his grandma’s recipes and organizing messy spaces—specifically tools. Josh Hutson grew up in rural Washington State. His family operated a sustainable organic hobby farm in addition to logging and excavating. Hard work and family values weren’t talked about as much as they were lived. In 2004, Josh left high school to enlisted in the United States Marine Corps where he deployed twice to Iraq. He was later awarded a scholarship to attend Norwich University in Vermont and was commissioned as a Second Lieutenant upon graduating with a degree in History and Creative Writing. He has held roles at the US State Department and most recently was the Director of Business Development at a regional construction firm. Josh is committed to excellence. He enjoys providing long lasting solutions to complex problems, and is ultimately driven by wanting to help and serve. Josh lives in La Crosse with his wife and three children. He enjoys playing in the park near his house, eating ice cream and shooting things from very long distances.

Basement Leak Repair questions, answered by experts

The frequency with which a French drain clogs depends on various factors, such as the amount of debris that enters the pipe, the quality of the French drain installation, the type of grate and filter used, and how often it is maintained. That’s why it’s recommended to clean your French drain at least once a year, whether it is clogged or not. This can prevent clogs and increase the lifespan of your drain.

Inspect regularly for clogs, clean drain lines, and ensure grading directs water away from the foundation.

Mold and mildew are the things in basements that actually cause the musty odors, but moisture is the underlying issue that causes mold and mildew growth. Addressing moisture and water problems and then removing materials that are moldy are some of the best ways to get rid of the musty odors. Preventive measures after that—like installing air fresheners and a dehumidifier—can help keep musty odors from returning.

Waterproofing or encapsulating protects against moisture, preventing mold growth and structural damage. These services also enhance energy efficiency and improve air quality by keeping humidity levels in check.

The best basement waterproofing method depends on the issue you’re trying to solve. For example, if you have standing water on your basement floor, a floor drain or sump pump might be your best solution. Or, if you have standing water around your foundation, installing a drainage system that protects your basement and foundation might be better.
