" I’m So Happy With My New Kitchen! I had my kitchen remodeled recently by CA Cabinets Inc., and I couldn’t be happier with the results. The quality was outstanding — beautiful materials, smooth drawers, elegant countertops, and a clean, modern design that completely transformed my home. Lior and his team were professional, quick, and very easy to work with. They kept everything clean, communicated clearly, and delivered results that exceeded my expectations. I’m truly thrilled with my new kitchen. If you’re thinking about remodeling, this is the company you want to hire!"

"Leo was very helpful and quick to respond. We’re happy with how our 2 bathrooms turned out. Project was completed within the time promised. Our only complaint is that the workers did not clean up very well. But overall, we’re satisfied and we’ll use them again. "

"Nextgen Home Repair did our bathroom remodel and they did such a great job. Honestly what I liked most was how easy they made everything. Remodeling can be stressful, but they kept us updated and explained things clearly along the way. The attention to detail really stood out, the tile work looks amazing and everything feels solid and well done. They were respectful of our home and made sure things were cleaned up at the end of each day. The finished bathroom looks modern and exactly like we envisioned it. I would absolutely recommend them."

FAQs for basement remodeling projects in San Marino, 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.
