" 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!"

"THE WORST EXPERIENCE EVER! We signed a contract with Yakov to design an ADU. He raved that his engineer was on his staff as an employee and that she previously worked for LA planning so she understood how to more efficiently complete plans to be done sooner. The mistakes and time in between for her to submit corrections were so long there was no reason for it. When we were given so many excuses I contacted the city myself to get a true timeline and found that the corrections were issued by city and they were very basic items that any engineer should not have even had an issue with and weeks and over 2 months would go by that she did not respond to the corrections. When we reached out to Yakov to get resolution he brushed us off and said we had to handle it with the engineer. He did not always respond to calls. I had to excessively call them both to get the work done. It was nearly two years of stress for the plans to finally be complete and approved with the city. Suffice to say we di"

"Horrible company to deal with. They came out to help to bring the elevator to the first floor. It was stuck due to a power outage on the block. They came out at 3pm Thursday and overcharged us overtime and travel time. As you can see from their publish hours 3 pm is within their working hours. They didn't tell us the overtime rate nor tell us that we would be charged over time.The service took under 45 minutes. Smartrise billed us for two hours at 454.00 an hour, total 908.00. When I spoke to Art at the company trying to discuss the proper amount for this service, he used profanity and name calling. Art hung up on me rather than communicate."

"Efrain came several times to the property so we could discuss design aspects. He was so patient with me as well as the changes I made each time before I got a quote and he started work. We had a difficult area to have work done in Venice being in the middle of the block and our back alley too small for a standard construction truck to fit. Efrain investigated and figured out the best way to get the excavated soil out as well as the pavers and road base onto the property. Efrain is a man of great character. Once work began, he and his staff were incredibly respectful of our tenants, the property, and our neighbors. He was an artist in several areas, he leveled each and every paver by hand as well as used his expertise in concrete to direct areas for water to drain from the property during rainfall. When I decided to do change orders, he didn’t take that opportunity to charge me a vast amount of money because he knew I had no choice if I wanted the work done. He and his staff always cleaned up after themselves and made sure no one would be in danger of walking across an unsafe area. His work made such a huge difference to the quality and value of the property – it easily paid for itself. If you want an artist who prides himself on his work, Efrain is your guy."

FAQs for basement remodeling projects in Gardena, 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.
