"We hired Groundworks CA (fka Bay Area Underpinning) for what we understood was a full foundation repair. We paid $42K. They only worked on the rear and never informed us that the front wasn’t included. Months later, while selling our home, a third-party engineer found $189K in unaddressed issues at the front. We were blindsided, lost our buyer, and suffered major financial and emotional stress. Groundworks later admitted they hadn’t measured the front. Their rushed “final inspection” months later felt reactive, not professional. When asked for a partial refund, they refused. We feel misled and abandoned. Avoid."

Basement Waterproofing questions, answered by experts

Yes, you can add a bathroom to an unfinished basement, but you’ll want to take proper precautions if doing so. As with any bathroom addition, you’ll need to make sure that it’s approved by local building authorities first. With unfinished basements, you especially need to keep an eye on proper ventilation practices.

Foundation problems will likely get worse over time if they aren’t repaired. As foundation problems progress, your home may experience signs of structural damage, water damage, and health and safety risks—all of which will only get more expensive to fix the longer you wait. Repair foundation problems as soon as you’re aware of them to avoid complex and expensive remediation in the future.

You can DIY basement waterproofing in some ways to help save on the overall costs. If your basement isn’t experiencing a lot of water but is noticeably humid, you can try running a dehumidifier that will pull the excess water out of the air. If you notice water leaking due to outdoor drainage issues, you can add downspout extensions to keep rainwater away from your home. 

However, if the problem is more severe and requires a more extensive solution, it’s best to call a basement waterproofing professional to assess the treatment you need and install waterproofing safeguards properly. Since keeping water out of your basement is important, ensuring this job is done correctly the first time is best.

The most flood-resistant materials you can count on in a flood scenario are concrete, closed-cell insulation, foam insulation (also known as expandable foam), pressure-treated wood, marine-grade plywood, and ceramic tile. When a material is flood-resistant, it can withstand direct contact with floodwater for at least 72 hours without being significantly damaged.

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.
