"The employees were great. A couple of days there was only 1 man on the job due to illness. The company did not replace him, so the 1 man had to work alone, slowing down the completion of the project. Art and Johnny were great to work with. Communication with the office was a little lacking, but overall we are happy with the work."

"So they’ve constructed many different things in my mother’s home now. From bathrooms to and a series of home improvement projects—most notably a complete bathroom remodel, as well as various upgrades and repairs throughout the house—and the experience exceeded all expectations. From the very beginning, the professionalism and attention to detail stood out. They treated our home as if it were theirs, ensuring that every fixture, tile, and finish was executed with precision and care. The bathroom transformation was truly stunning—sleek, modern, and remarkably functional. What impressed me most was the seamless coordination of multiple trades, and how effortlessly he managed the timeline while maintaining an exceptional standard of quality. Not to mention the very affordable pricing! Beyond the bathroom, he tackled several other improvements—drywall repair, custom carpentry, tiling, and fixture installations—all done flawlessly.

FAQs for basement remodeling projects in Sebastopol, 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.
