"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. "

"I have continually asked SB Construction to stop posting pictures of my home for advertising purposes, and they refuse to do so. This is why I feel the need to share my experience… the pictures they post do not reflect the quality of their work. There are multiple problems the contractor committed to fixing, and while blatantly ignoring my texts, he continues to post. It’s tacky and unprofessional. The dishonesty in saying this was a full home remodel is also incredibly frustrating. This remodel was supposed to be for my entire home. We agreed to start on the top floor with a 6 week time frame and then move onto the second floor. Well that 6 week time period turned into an entire year and I refused to move forward with this company for the remainder of my home. It was a horrific experience and the aftermath of the low quality work continues to haunt me a year and a half later. I have had to fix multiple issues and have spent thousands redoing their subpar work… yet the company continues to post the pictures. The pictures you cannot see are the walls left opened underneath the sinks… the leaks from the brand new sliding doors after every single rain… the damaged baseboards and flooring (both brand new) because of the nonstop leaks… the freshly painted walls bubbling up because the painters did not use the proper primer… the electrical issues that required walls to be reopened to assure that the live wires were no longer a safety concern… the dents and chips over all of my “custom wood cabinets and niche” that turned out to be MDF and not wood (as discussed). The list goes on and on. So many lies and so many mistakes turned this 6 week project into an entire year of frustration and lost money. There was also a constant turnover of subcontractors. To cover up that they had actually quit, the contractor would blame me. I maintained relationships with several of them who have helped me with my issues post remodel now that they are no longer working with Ron and his team. The original carpenter let me know that Ron specifically asked him to use the cheapest material and that is why they went with MDF vs wood. The carpenter that replaced him also told me Ron asked him to do the same. The subcontractors constantly complained about the lack of communication and would bad mouth the team whenever they were in my home. Because of the constant turnover due to the subs always quitting… because of the lack of attention to detail due to working on too many projects at once… because of the dishonesty and low quality work that was a constant theme throughout the project, I would feel guilty not sharing my honest feedback. When I saw someone else recently experienced the same nightmare, I felt bad for not sharing my experience sooner. If this review just helps one person not go through what I had to go through, then I feel obligated to share an authentic review."

Nir and his team started this project on time and it was a true pleasure to work with them. Nir was very knowledgeable, communicative, honest and helpful. He and his team finished this remodeling project in a timely manner and final outcome s great. I really like my new kitchen! Thank you Nir and LA Expert Builders!"

FAQs for basement remodeling projects in Newbury Park, 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.
