"We are completely satisfied with our backyard, where we wanted to do a complete renovation, making our yard more beautiful and usable, for games with friends, easy access for my dogs and everything else! From the beginning Brian helped us with the choice of materials, locations, colors and many great suggestions. Our Project Manager, Delmar, and Brian did an excellent job updating us and communicating and always responded quickly to any questions or concerns. We had a tight deadline for our project because we wanted to finish before 06/01 - he did our entire project quickly and efficiently! I want to thank you very much, I am very happy, I recommend Geico Builders and together with Brian for all your projects! I hope to work with him soon on our front yard, after all I only have good things to say!"

"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). "

"This was the second time we hired Alan for a project and we will certainly hire him again if something comes up in the future. Once again we were very pleased with the professionalism, communication and quality of work. We also appreciated Alan's suggestions and expertise. This is a rental house and we needed to put on a new roof, replace the old siding, replace 3 windows, and paint inside and out in less than a month so the new tenants could move in. Alan was able to schedule and complete everything on time. He coordinated well with the roofing company. Alan is excellent at communicating, providing updates, and was always available to discuss the project. He is great to work with. The quality of the finished product was excellent. The painting crew was not as diligent about clean up as we would have liked but, once we pointed something out, they took care of it promptly. We were very satisfied overall with the work and would highly recommend Alan for jobs both large and small."

"25 years at this house and in wet winters we would have a damp smell coming up from the crawlspace. Rats were out of control too. We had sump pumps all around the house. Always cleaning or replacing or re-setting GFI outlets. I did it all myself. Finally I called his company to replace some sump pumps. Estimator came out and said they don't do that. They encapsulate the crawlspace. I said what about the pumps? He said it won't matter any more. I went for it. <br /> They just left and couldn't wait to get underneath and look. I am very pleased with the workmanship. If you look at the photos (hey angie can I post photos?), they fastened this 20mil reinforced plastic sheeting to the sides of the foundation using rivets. Not a bit of dirt or debris to be seen. The crew was very professional. Very polite, lots of drop clothes to protect the floors. Their workmanship was very good. If they were my crew, I would be very pleased. <br /> Just a word of caution - not a deal breaker but...the first day required a lot of dirt work. Invariably the house became dusty. I would have put painters tarp over couches and other soft surfaces. Second, don't be surprised to have some smell of epoxy - the material they use to glue the sheets together. It goes away in a day. It's part of the install which makes me happy they use it. So far I'm very happy with the job. <br /> <br /> <br />"

"We were incredibly pleased with Mulhall's performance.  We found Mulhall to have professional and dedicated staff, clear and transparent accounting, and most importantly, exceptional quality work.  Communication was direct and appropriate as issues arose and was always accompanied by options as to how to solve the problem.  They were very collaborative highlighting concerns and laying out solutions as we worked through the inevitable decisions that crop up.  We worked with Ronan Agnew primarily and Fiona in the main office for finances.  We had complete trust in them both and all the sub-contractors brought on for individual projects.  Tile, cabinets, wood floors, heating duct work, electrical; everyone was an expert in their field.  We would not hesitate to recommend this company or use their services again. They made what can be a complicated and arduous process simple and easy and we are thrilled with the end product."

"Dan went above and beyond as a Contractor. We were having a great deal of difficulty with our Insurance Agent. We were doing everything he requested but it was never enough OR something we had no idea how to handle (ie, what questions we should ask regarding permits, estimates, and other details we felt the Insurance Agent had surely dealt with in other circumstances but he was putting on our shoulders). From a list of agents, provided by the Insurance company, we fortuitously picked Morgan Construction. He held our hand, he fought on our behalf, he became a voice of reason between ourselves and the Company. He gave us several months of his time which we are eternally grateful for. The work he performed was impeccable."

FAQs for foundation, basement or crawlspace waterproofing / encapsulation projects in San Mateo, 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.
