"The Groundworks folks (formerly Bay Area Underpinning) applied their foundation-underpinning technology and expertise to extend to bedrock, level, square up the foundation for an extensive house remodel. I was most impressed by the young man onsite supervisor, Josh who answered all my work done, how and why questions. I wish this info was provided up front by the estimator. (My design-build remodel contractor referred this company)."

"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!"

"They were okay. I had an upstairs bathtub and it was leaking a lot and they fixed it. They put a steel mesh around the tub so that the rodents couldn't get to it. He went above and beyond. I am satisfied with his work. He is very communicative, explains things, tells you what he did and what he found."

"Armin and Andres did an outstanding job. They managed to open a stuck brass clean-out cap by cutting it and removing the pieces, then replacing it with a new plastic one. They snaked and opened the plugged drain after having to cut back a bush. They found a suspected offset in the line and recommended a visual inspection. They managed to do all this in a very short time. I would gladly recommend them to anyone anytime."

"It was great luck that Jason of J Drains was working on a job near my home and was able to come by after he finished that job to check my hot water heater. He fixed it right away because he spotted what was wrong quickly. Jason was very professional and polite. I recommend this company!"

Basement Waterproofing questions, answered by experts

Yes, these services often increase home value by preventing moisture-related issues and enhancing the usable space in basements or crawlspaces.

No, your basement dehumidifier doesn’t need to be on 24/7. While it’s an excellent tool for tackling damp, musty air, especially in humid seasons, leaving it running nonstop can backfire. Over-drying the space can mess with your sinuses, warp wood, and even crack certain materials. Instead, only use your humidifier when moisture levels rise above 50%, and then give it a break when the humidity levels drop.

There are a few downsides to a wet room, the most important of which is the risk of mold growth from the moisture and humidity. Standard bathrooms can have the same issue, but wet rooms are more likely to experience problems because water is less carefully contained. You also have less privacy since the entire bathroom is open, and the room must include waterproofing, which makes wet rooms more expensive to install than regular bathrooms.

No, you don’t want your crawl space to be wet because water and even moisture in the air under your home can attract insects and rodents, decrease your indoor air quality, increase your energy bills, promote mold growth, and even lead to structural damage. If you notice any signs of water or humidity in your crawl space, you should get the issues addressed immediately by contacting a professional. They can remove moisture and will know how to waterproof your basement to prevent ongoing problems.

Many prevention methods can be used individually or in combination to waterproof your basement. Some of the most common waterproofing methods include:

  • Using dehumidifiers 

  • Silicate concrete sealers

  • Vapor barriers 

  • Baseboard channels 

  • Drain tile systems

  • Waterproofing paint

  • Drainage systems

  • Epoxy injection

  • Interior French drains

  • Exterior excavation and waterproofing

  • Cement waterproofing

  • Weep tiles

  • Liquid membrane

  • Sheet membrane 

  • Yard grading

  • Gutters and downspouts
