"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."

"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. "

"We found Golden State HS after our last contractor didn't quite meet the standards and really put a bad taste in our mouth in regards to contractors. All of that changed once we decided to work with Lilith and her team who not overseen the project but ensure our new home was built beautifully and even better than we could have imagined it. We loved how thorough Golden State HS's team communicated every step and the reality of the process. Now we not only have a wonderfully constructed home with a pool, tennis court and beautifully landscaped property (they do it all), but we have what really feels like home. I would not only be reaching out to them for my next project, but i will also be referring them to everyone we know."

"Jose, Jesus, and the whole crew are awesome. They put in the foundation, framed, and sided a new addition and did a great job. I have worked with a lot of contractors and Alvarado and Son are amazing. Their price was reasonable, the speed of getting the project done was lightning fast, and the whole crew are really nice people that you just like to have around. I have never had a foundation come out as dimensionally correct as they built it and their framing was outstanding. I literally had the city inspectors giving them compliments ... which just doesn't happen normally. If you have a similar project, look no further! "

FAQs for basement remodeling projects in Antioch, 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.
