"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

The foundation repair that will work best varies based on the extent of the damage, the underlying cause, soil conditions, weather conditions, and more. Permanent foundation solutions like underpinning and exterior drainage solutions are better than temporary fixes that don’t address the source of the issue. Some examples of more temporary solutions include mudjacking or slabjacking, waterproof paint, and dampproofing. The best course of action is to have a reliable foundation specialist inspect your issue, treat the underlying problem, and restabilize your foundation.

The only real negative when encapsulating a crawl space is that the cost is high. It can cost several thousands of dollars to do this project. However, it protects your house and those in it by providing an energy-efficient space instead of one that frequently pools moisture and causes damage through mold growth in your home. While less common, another disadvantage could be encapsulation making access to pipes and electrical slightly more complicated in certain crawl spaces.

The process might take a few days to a week, depending on the method chosen, area size, and weather conditions. Some solutions, like simple interior sealants, may require less time.

The difficulty of adding a basement to an existing house can vary depending on the house’s location, the size of the basement, and the type and condition of the existing foundation. Adding a basement is a job best handled by the pros, so you’ll need to enlist professional help for this project.

While it’s possible to live in a damp basement, it’s usually not healthy to do so. Damp air affects your breathing, and it also promotes mold growth and pest infestation that can make living in a damp basement dangerous. You should plan to resolve any moisture issues and set up preventative measures before using your basement as a living space.
