"I'm renovating an old zombie house, and the basement was in terrible shape - humid, cracked floors and walls and foundation issues both inside and out. I met with several contractors, but most only focused on their own niche, never offering a comprehensive fix. Then I met Jack - Basement Man. He was the only one who looked at the full picture and pointed out issues that others missed. Jack was professional, thorough and honest. He took the time to walk me through my options, never trying to be pushy or upsell me on things I didn't need. He was on-site everyday, led a hard-working team, and turned my basement into a clean, solid and completely revitalized space. His communication was consistent and clear throughout the project. The results were beyond my expectations. I'd hire him again in a heartbeat and highly recommend him to anyone with basement and foundation challenges."

Basement Leak Repair questions, answered by experts

Heavy rain can affect a leach field because the extra rain can cause the groundwater level to rise. This leads the soil around the leach field to become saturated with rainwater, so it’s no longer able to take in effluent from the leach lines for final treatment. Heavy rainfall can cause the leach field to flood.

Due to the nature of basements, some level of waterproofing is necessary to prevent water from seeping in and causing damage. Some definitive signs that your basement needs waterproofing measures or needs existing waterproofing measures need to be updated include:

  • Water in your basement, including damp walls or puddles on the floor

  • Mold spots in your basement

  • Musty smells or odors

  • Warped doors or walls

  • Cracks in walls

  • Insect issues, such as cockroaches and termites

Yes, you can finish a basement that leaks, as long as you address the leak first. Before finishing a basement, you’ll need to repair any cracks in the walls and waterproof the basement to prevent future leaks. It’s much harder to clean up a water leak from a finished basement than an unfinished one, so preemptively addressing any leaking areas prevents expensive repairs in the future.

To ensure your basement walls are waterproof, it's crucial to address any existing moisture issues before finishing. Inspect for signs of water seepage, such as dampness or discoloration, and repair any leaks or cracks. Install a vapor barrier to prevent moisture from penetrating the walls, and consider waterproofing paints or coatings.

Proper drainage systems, such as interior or exterior waterproofing, can also be beneficial.

The least expensive basement waterproofing methods include grading soil away from your home, installing downspout extenders on your gutter system, and applying a waterproof paint on the interior of the foundation walls. Installing a French drain is a relatively inexpensive method if you do the work yourself, although it’s labor-intensive and can be challenging to install properly.
