Quartz countertop, beautiful backsplash, new modern lighting, and tile flooring. Everything at a good price. I highly recommend them to everyone I know If you are looking to remodel your home, give them a call."

"The team I worked with at BAU was great. I hired them to repair some minor vertical and horizontal foundation cracks that were found in a recent general home inspection. Everyone who came out was upbeat, professional, punctual, thorough, and highly detailed. Hunter came out first to check the entire foundation and give a free estimate. They then split the work up into two dates, and each crew was great. Michael and James came out first for the initial round, and then Alexander and Gabe came out to wrap up the last few areas. The guys were always on time, which is greatly appreciated. Both repair teams also did their own additional checks of the surrounding areas, also greatly appreciated. They were also able to provide before and after pictures, and were respectful of the property."

"A million thank u's to Declan, Jackie, Vince, Alex and Holden. Job well done! My bathroom and loft look wonderful. I was very nervous about this project. Had a previous issue with someone else who ghosted me and left my vanity in the dining room. Nice huh? Luckily, Jackie called me though Angi's list, booked an appointment and the rest was magic! Attention to detail, quality and accountability describes this company. Thanks again everyone! I'll be seeing you in the spring! "

"Dana was the foreman on a major remodeling project on our property. We added a guest cottage which involved excavating over 100 ft.³ of hillside, foundation, as well as construction. He also remodeled the main house extensively from a concrete pour to new roof, electrical flooring, fine carpentry and everything in between. Throughout the 2- year project, Dana was attentive to detail, honest, mindful of the budget and schedule, and collaborative on creating solutions. He is such a kind hearted person, and was a pleasure to have around the home. I canâ t say enough good things about String Theory Construction!"

FAQs for basement remodeling projects in San-geronimo, 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.
