"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). "

"Project kickoff began with an evaluation and a quote from a Ned Clyde engineer. After accepting the offer, we waited for 3 months to begin work due to high demand for their services. Project work spanned about four weeks, with some downtime due to weather. Aside from the main work of returning the floor and walls to original positions, the french drain along the foundation was remade with modern material. This work required a permit from the city of Martinez that required adding an earthquake shutoff valve for the natural gas service and a check for smoke and carbon monoxide detectors matching current codes. The cost of these upgrades were outside of the feeds paid to Ned Clyde, but they are sensible requirements that would have been done eventually anyway. Overall, the Ned Clyde folks are experts who did exactly what they promised with no required feedback. Costs were in line with other quotes, but I got the sense that I got a great bargain in value provided."

"Peter did a great job from start to finish.  His knowledge of the process and expertise in applying the chips and epoxy turned my garage into a real showcase.  I was especially impressed with his work ethic as he started and completed the flooring in one day which required him to dedicate an entire  Sunday to this job.    I enjoyed dealing with Peter and would highly recommend him whenever the occasion arises. <br />"

"For several years, during and after periods of rain, water (as much as an inch) has accumulated in parts of our basement. Other parts have gotten very wet from the water draining down towards an existing sump pump. I waited to do a report until we had gotten some rain and while this year has not been exceptionally wet, there was enough rain to convince me that the problem in our basement has been solved. The entire process went smoothly and everything was handled with skill and attention to detail. I had gotten other estimates which were higher than Bay Area Moisture Control and I am not sure that the work suggested would have solved the problem. In summary, the parts of our basement that were getting very wet are now dry."

"Adrian was always easy to communicate with and work with throughout the project and provided terrific on-site oversight. The job was done on time and on budget and, as much as possible for a large project, the job site was kept neat. Based on my experience with Adrian, my family members have since used Mulhall Construction for foundation work on their homes and been pleased with the results, as well. I enthusiastically recommend Mulhall Construction!"

"We wanted a solar structure built detached from our home to accommodate 24 solar panels.  The design requirements went beyond a normal scope.  The steel supports were very tall and over 600 lbs each.  They had to be "planted," encased in rebar, into 10' deep holes.  To me, daunting, to Ben, no problem.  That went very well.  And then the 6" x 12" wood beams had to be positioned at the tops of these steel supports 15' high.  Again, no problem.  From there, the roof went on and the structure went up quickly with great attention to every design detail.  Ben and his capable crew were very punctual, professional, and we are extremely impressed with the project.  Ben is my contractor and I will call him for any home improvement that comes up.  Excellent work from an A+ contractor.  "

FAQs for foundation, basement or crawlspace waterproofing / encapsulation projects in Castro Valley, 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.
