"We hire Geico Builder to handle our home renovation, including updates to the kitchen and bathroom, and the whole experience was fantastic. The team was professional, organized, and easy to communicate with from start to finish. They showed great attention to detail, stayed on schedule, and made sure everything turned out exactly how we envisioned it. Our kitchen looks stunning, the new bathroom layout is so much more functional, and the bedrooms feel brand new. It's rare to find contractors who combine quality work with honesty and reliability, but Geico Builders delivered on all fronts. Highly recommend them for any home remodeling project."

"The job included prepping and painting my 1400 sq ft home and picket fence. It also included demo-ing the old window boxes that were structurally built into the walls, and custom-building new ones. In addition, a garden shed that had been built onto the back of my home was also demolished. Ivan was great to work with - very collaborative and responsive and has a good eye for esthetics. The work was exceptionally high quality. The team shows up early and works hard. It was also super-convenient that Ivan is licensed in carpentry as I didn't have to deal with custom window-boxes as a separate project. Last note is that as a single woman, it is important to me to feel comfortable with the people around my home. Ivan's team, including his wife who is often onsite, are so friendly and always respectful. They will be my go-to for all future projects."

"Ovation Restoration did an excellent job with our home improvement project. In our master bedroom, to take advantage of a fantastic view, they removed a large window from one wall, sealing it up like new, and installed a similar window on another wall. The work was performed quickly and skillfully, with great results. They also turned the double door leading into that room into a single door, creating more space in the room. Concurrently, in the guest bathroom, the old tub was removed, and a beautiful walk-in tiled shower was installed, along with a window with a fantastic view. The project manager Rick was a pleasure to work with, and his team were all professional, conscientious, and friendly. Everything turned out just as we imagined. We would highly recommend Ovation Restoration."

FAQs for basement remodeling projects in Belmont, 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.
