"Thank you Bay Area Underpinning for saving the day! I was in a challenging and prolonged situation since going into contract with EagleLift for the stabilization/lift for my house. After a long permit process and continuously delayed start dates, I was informed that EagleLift had been acquired by Groundworks and I’d have to wait a few more month before any progress could happen. It was a deeply frustrating process but the EagleLift team was able to connect us with Bay Area Underpinning (another Groundworks company) who were able to take over and expedite the project. To my surprise, James T. from BAU reached out quickly and assigned a team to come to my house within a week! The team that ended up working on the house, specifically Ish, John and Abel were exceptional. They were diligent, knowledgable, friendly and deeply considerate. They are truly pros who knocked the project out in no time which was reassuring since I was nervous that this project was gonna stretch into the rainy season. My house feels so stable now (minimal cracks too) and the considerable slope is now practically nonexistent! Thanks a lot James T., Ish, John, Abel and the BAU team for taking really great care of us."

"Had Evan come out to clear an overgrown lot full of vegetation and an old concrete pad. He was very professional and made light work of the lot with his machine. Great attitude and I now have a nice level lot to park my RV. Can't recommend this guy enough"

"We worked with Ali (sales manager) and Tony (project manager), who took the time to design a project that made sense for our property and our budget, made a number of suggestions and recommendations and were never pushy or tried to "sell" us on something. The crew really went above and beyond to provide top quality workmanship and overall we were in very good hands. Highly recommended!"

"I called Crieg looking for someone to help get a rental in top shape so I could sell. He was responsive and very accomodating. He approached things methodically and had attention to detail, I had quite a laundry list of things to get done from as simple as chalking 2 skylights of which one leaked causing damage to the interior ceiling requireing the drywall replacement. Crieg was versatile and was able to handle anything I threw at him. I kept him busy for about 50 hrs and it was money well spent. One of the only people I could find on AL to work on a straight dollar per hr basis.

"Called superior plumbing before years ago and they did a great job. Today I called for a residential property, and Armin came at the agreed hour. He was polite, friendly, and hard-working. He also made sure to take of covid precautions and kept the work place clean during and after service. The rate was fair."

Basement Waterproofing FAQs, answered by experts

The best ventilation for a crawl space is a fully encapsulated crawl space with its own separate ventilation system. If you go this route, ensure you have the proper crawl space code requirements done and dusted before encapsulating your crawl space with a moisture barrier and installing appliances that may not be up to the proper specs.

While it’s possible to seal a foundation yourself, it’s not recommended, as it’s a tricky and labor-intensive job. Foundation sealing is best left to the pros to save yourself time, remove the risk of doing it wrong, and keeping yourself safe. Call a foundation repair professional near you to see what the job will cost.

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.

When doing any type of project involving mold, it's important to wear the right protective gear. You'll want an N-95 or KN-95 mask to keep yourself from inhaling mold spores, which can be irritating or trigger an allergic reaction in people with weakened immune systems. You'll also want to wear protective eyewear and gloves to limit your contact with mold.

In most cases, a crawl space will not dry out on its own unless the moisture comes from an uncommon flood and isn’t expected to be a recurring issue. For most homeowners, moisture problems in the crawl space will only continue to get worse over time, so addressing the underlying problem with gutter systems or a foundation drainage system and setting up a preventative solution like a dehumidifier is necessary.
