"The entire project took 9 days and involved a crew that was exceptional in every way. From Terrie to Tom, Rich (the owner), Alberto (the project manager), Eusebio (Alberto's right-hand man), and the entire team--they were the most respectful, diligent, patient, and fexible crew I've ever worked with. The quality of their work was outstanding, and they took great care in respecting our property while delivering an excellent solution.

"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

There are several small, inexpensive upgrades you can make to upgrade your basement. Although you still need to adhere to building codes and obtain permits when necessary, you can complete small but mighty tasks like painting the masonry walls and installing entertainment devices to make the space more usable. 

Yes, engineers assess soil load-bearing capacity and provide construction guidelines.

Mold can grow anywhere in your home where there’s moisture that doesn’t dry out, usually in areas that are either not ventilated properly or where moisture gathers continuously. Insulation, drywall, and foundations typically provide mold with areas to grow if moisture is present and does not have a chance to dry out. Some of the most common areas in a home for mold growth include:

  • Attic

  • Walls

  • Bathroom

  • Crawlspace

  • Basement

Proper drainage prevents water damage, mold growth, and foundation settling, protecting your home’s structural integrity.

In most climates, contractors recommend closing your crawl space vents in winter. Keeping them shut protects your crawl space from freezing temperatures, pests, and cool breezes that can lead to chilly floors in your home. However, it's often best to speak with a local crawl space team about your specific design and its relationship to the winter season.
