"My journey began when I met Mario from Be Home Remodeling. I started with just one bathroom remodel, and I was immediately impressed by the professionalism, attention to detail, and high-quality craftsmanship he and his team delivered. The communication throughout the project was clear and consistent, and they made sure every step met my expectations. Since then, I?ve trusted Be Home Remodeling with additional projects and have always been more than satisfied with the results. Highly recommend Mario and his team to anyone looking for reliable and high-quality construction work"

"Roger and his team were great. It started with a very detailed proposal. And we had great communication throughout the project. His crew were polite and professional and had some good recommendations as well. The project was done on time and within budget. Roger was really nice to work with and we would definitely get another proposal from him in the future."

"We were impressed with Prosper construction from the start. We were looking to remodel our kitchen and as that project progressed we added on it. I can not express enough how wonderful the crew was. David, the project manager was very professional and kept his word through the whole project. The crew on site were always on time. The job was beautifully done; and we are currently working with them on a full master bedroom remodel! Ultimately our needs were met with the first project so it was none barriers to proceed to another project. The whole team is incredibly professional and trustworthy, highly recommend!"

"This project was for remodeling 3 bathrooms and a total kitchen remodel. The construction workers were very skilled. They were very good about listening to our suggestions along the way. I would suggest that the construction foreman be present along with the salesman when the project is estimated so that technical issues and be better clarified. For example, we removed carpet and installed DVT vinyl flooring which resulted in different leveling issues. These issues could have been resolved early on rather than brainstorming solutions with the workers at the ends. The project was done on time as scheduled even though we added some changes along the way. The electrical subcontractor should have clarified options for wiring for the kitchen better. The only negative comment I can make is that we thought the cost was a little high, however the quality was very good. The final project is beautiful."

"Within a few months of buying our first home, we noticed some troubling signs: bedroom doors swinging open or closed on their own, “bubbles” and creaks in sections of the newly renovated floors, and significant cracks splitting the concrete in our garage. Although two general inspectors assured us that our house was level, we reached out to Bay Area Underpinning (BAU) for a more detailed assessment—and we're so glad we did! Inspector Christopher Murray conducted a meticulous inspection with radar equipment. While technically our house was level, Christopher uncovered that our foundation was sinking by inches in multiple areas, explaining the issues we were experiencing. Though the news and associated repair cost were a bit daunting as new homeowners, Christopher’s knowledge, professionalism, and clear answers to all our questions reassured us that we were in good hands. With confidence, we decided to proceed with BAU for the repair. Fredy Mora and his crew did exceptional work with the demo of the old concrete slabs and the prep for lifting, working quickly and efficiently. Fredy’s positive attitude made the process smooth, and his team was thorough and dedicated from start to finish. A special thank you to our lift project manager, Kevin Gaeden. Kevin was an outstanding communicator, keeping us fully informed and addressing every question promptly. His attentiveness made a huge difference throughout the project, and we felt reassured every step of the way. Esteban Ibarra, a crewmember on the lift team, also did superb work, handling the hands-on details with skill and care. Both Kevin and Esteban even went above and beyond, taking time to fix a jammed bedroom door that had shifted with the house lift. While foundation issues are never easy, we couldn’t have asked for a better team. We’re incredibly grateful to Bay Area Underpinning for their expertise, professionalism, and exceptional service. Thank you, BAU!"

FAQs for basement remodeling projects in Mill Valley, CA

Finishing a basement turns unused square footage into livable space and returns up to 70% of what you spend when you sell your home. Beyond that resale boost, you gain a playroom, home office, or guest suite you can start enjoying right away. That mix of daily comfort and solid return on investment (ROI) makes basement finishing one of the smartest upgrades you can tackle.

In some parts of the country—especially lots on swamps, high water tables, or other wetlands—local codes prohibit basements. Saturated soil puts constant pressure on foundation walls and lets water seep in faster than any sump pump can handle. 

If your property sits on waterlogged ground, building on a slab or crawl space is often safer, more affordable, and code-compliant.

Most basements wrap up in four to eight weeks. Framing takes three to five days, with electrical and plumbing rough-ins following over the next week. Add five days for drywall, two to three for flooring, and another week for paint, trim, and punch-list items. 

Delays can happen if materials run late or your contractor’s calendar is packed, so build in a little cushion when you plan.

Whether a finished basement counts toward your home’s official square footage depends on local rules. Many areas only include below-grade space if it has code-approved egress, fully finished walls, ceilings, and floors, plus consistent heating. 

Check with your local assessor or building department before you start; meeting those standards can affect taxes, appraisals, and resale value.

Building codes require a checklist: dedicated heat and electrical service, a code-approved stairway, and at least one egress window or exterior door. Walls, ceilings, and floors must be fully finished and meet insulation, ventilation, and fire-separation standards. If you add a bedroom, you’ll also need a closet, proper clearances, and safe exits. If you change the layout later, be ready to update the space so every new room still meets today’s code.
