"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."

"My wife and I worked with Joe to renovate our home in the South Bay. We basically tore everything down to the studs and did some reconfiguring of the interior, as well as redoing all plumbing and electrical. With Joe and his team, we transformed a home that hasn’t been renovated since the 60’s to the home of our dreams. We were referred to Joe by a trusted friend, and after a phone call with an overview of what our plans were, we met Joe in person at our home for an initial walkthrough. Both my wife and I were impressed with how thorough he was with details regarding the renovation; it was immediately obvious he was a master of his craft, with a vast amount of experience and knowledge in construction. More importantly, he’s down to earth and honest; his transparency was very much appreciated. Joe and his crew take pride in their work. He’d go above and beyond by suggesting certain looks or practical modifications to our original request; it often felt like he was renovating for himself! For the project, he provided a clearly marked timeline and walked us through all the options for both finished and unfinished materials. His encyclopedic knowledge of stores in the Bay Area saved us a lot of money, and we got exactly what we wanted to build our home with! Home renovation is never a easily forecasted task; there are many surprises or issues that come up. With Joe, we knew we were in good hands. When a challenge did come up, he made sure to explain the options to us and address it immediately. Communication is key in this process, and Joe excels at it - he’s very responsive by phone and text. His crew is polite and also share Joe’s willingness to educate and explain the process. All in all, we felt that Joe became a family friend in the construction business and have recommended him to multiple friends and family. If you are looking for top quality work, reasonable pricing, and a trustworthy expert, look no further than Joe Arielli and his team!"

FAQs for foundation, basement or crawlspace waterproofing / encapsulation projects in Walnut Creek, CA

The most affordable way to waterproof your basement is with interior methods like waterproof paint, costing between $1 and $8 per square foot, or silicate concrete sealers priced at $4 to $6 per square foot. However, these solutions are only suitable for certain issues. If your basement moisture is due to more serious problems like a cracked foundation, you'll need more extensive (and costly) repairs.

Absolutely! Waterproofing your basement is a smart investment that can increase your home's value. By keeping your basement dry and free of moisture problems, you protect your home's structural integrity and make it more appealing to potential buyers. Plus, taking proactive measures now can prevent costly water damage repairs down the line.

The time required to waterproof a basement depends on the selected method. Some approaches to interior waterproofing, like paint or sealant, can be completed within a day. Installing new drains or weeping tiles will need at least two to three days of labor. Any forms of exterior waterproofing that require you to excavate land will require an additional three days of work to prepare the ground.

Yes, basement waterproofing can significantly increase your home's value. A dry, leak-free basement is a strong selling point for potential buyers, enhancing your property's desirability and market price. Investing in professional waterproofing not only protects your home's structural integrity but also ensures a healthier living environment by preventing mold and mildew growth.

Waterproofing both the interior and exterior of your basement offers the best protection against moisture. Exterior waterproofing stops water from penetrating your foundation, while interior methods manage any moisture that does enter. If you must choose one, exterior waterproofing is generally more effective, as it prevents water from reaching your home's interior in the first place.
