"I highly recommend Groundworks for foundation concerns. They were very prompt with returning my call and providing a free inspection. I had concerns for my 103 year old home, especially a section of the foundation. Their Inspector, Bob Bloom, arrived on time, was professional and experienced, took time to answer all my questions (thank you for not rushing), and provided me with useful feedback on my foundation and options for repair. Bob gave an honest assessment with no sales pressure. Although I decided to defer foundation work at this time, I will definitely use them in the future."

Basement Leak Repair questions, answered by experts

Several factors can impact the cost of waterproofing your basement. Some of the most common cost factors include:

  • Location

  • Square footage

  • Cause of the water leak

  • Type of foundation

  • Accessibility

  • Waterproofing method

  • Materials

  • Contractor experience and availability

  • Engineering reports, if needed

  • Structural and other repairs

  • Permits

If you’ll be digging up your floor to get access to your pipes when putting in a sewer backflow preventer, this would also be a good time to take care of any other plumbing issues or renovations. For example, you could install additional pipes for a basement bathroom. Since the floor will be sealed over with concrete when you’re done, now’s a good time to take care of those bigger tasks.

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.

Yes, water and water vapor can seep through cracks in your basement floor, which means you should address all basement floor cracks, even if they don’t indicate structural issues. Sealing settling cracks and shrinkage cracks is a good idea to keep water and moisture outside where it belongs. Doing so can improve your indoor air quality, reduce the risk of mold growth, make your home more comfortable, and help prevent pest infestation.

Yes, the air from a damp basement can travel up into your living area through a process called the stack effect, so moisture, mold spores, and other debris in your basement air can all decrease your indoor air quality on your main floors. Additionally, damp basements can promote the rotting of building materials, which can damage flooring, insulation, and framing on your first floor in addition to materials in the basement.
