"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)."

"Home Advisor does not have the specific category for the work that was performed of replacement of graded retaining wall up my driveway and around a structure. The work utilized excavation, concrete, wood & construction. Cristian, the owner, was the epitomy of professionalism as with every crew member. Firstly, he did not try to sell me on something I did not want, much appreciated. The job was meticulously executed in record time at the price I could pay. This job has been on my bucket list for years... finally completed with a job well done!"

"The work was excellent. The project was completed in the exact time frame that I was told when I hired them. I had numerous estimates given and M&W charged me a third of what had been quoted by other contractors. AND THEY QUOTED ME FIRST. They were also kind enough to work in a few other small projects I hadnt previously planned. The owner William is very professional and his crew is as well. They did a wonderful job and I will definitely call them first before any other contractor when I'm ready for more work in the future!"

Basement Waterproofing questions, answered by experts

Having a trusted crawl space contractor is the key to great encapsulation. If you're not sure how to hire a crawl space pro, begin by asking your neighbors for referrals. Homes in your neighborhood will often have a similar foundation to your house, and personal recommendations are one of the best ways to find a contractor. Additionally, double-check that the contractor has experience with encapsulation as well as proof of their license and insurance.

Most houses will have vents in the crawl space. This allows for air passage and energy retention, which in many ways can help control the temperature inside the home. If you are able to consider the cost of a crawl space encapsulation, you may not need your crawl space vents at all. 

While a standard gutter system is widely considered the most effective way to prevent water damage to your home's foundation, several alternatives are available. These options can be used on their own in certain climates or as supplementary protection.

Common alternatives include:

  • Rain Chains: These are decorative chains that hang from the roof's edge, guiding rainwater to the ground.

  • Drip Edges: These metal strips are installed at the edge of the roof to direct water away from the fascia. While often used with gutters, they can be paired with a ground-level solution but are typically not sufficient on their own.

  • Rain Dispersal Systems: These systems work by breaking up the heavy sheet of water flowing off the roof, dispersing it over a wider area.

  • French Drains: This ground-level system uses a perforated pipe in a gravel-filled trench to collect and redirect water runoff away from the house.

  • Drip Paths: Placed directly below the roofline, these paths made of concrete, stone, or other materials prevent soil erosion and guide water away.

It's important to note that some alternatives like rain chains and dispersal systems may not be adequate in regions with heavy rainfall because they don't divert water away from the foundation as effectively as a full gutter system. Ground-based solutions like French drains can be very effective but are often more expensive and can affect your landscaping and curb appeal. Many experts recommend installing a full gutter system for maximum protection and using alternatives as supplementary measures.

Yes, water and water vapor can seep through cracks in your basement floor, which means you should address all basement floor cracks, even if they don’t indicate structural issues. Sealing settling cracks and shrinkage cracks is a good idea to keep water and moisture outside where it belongs. Doing so can improve your indoor air quality, reduce the risk of mold growth, make your home more comfortable, and help prevent pest infestation.

Basements with persistent moisture problems or flooding shouldn’t be finished until the moisture issues have been fixed. In addition, if your foundation is cracked, you have unmitigated radon levels, or you have asbestos or lead pipes, remediate the underlying problem before finishing your basement. Turning a basement into living space before fixing these issues can lead to serious health risks or structural damage.
