"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. "

"Our consultant Daniel and the rest of the crew were in the simplest terms professional, easy to work with, and fairly priced for The excellent work accomplished. Ultimately what more can you ask for when you're dealing with such daunting task as remodeling your kitchen which is what we did or any house projects for that matter. So many things go wrong and so many personalities can be rubbed the wrong way, but I'm happy to say everything went smooth and we were very happy with the final product. I have already recommended AP remodeling to family members and strangers alike. If you're looking for a company that is straight up honest with communication and pricing and expected results, then look no further."

"We used Ivy Builders to remodel a 30 year-old bathroom in our 60 year-old house. Nathan and crew were outstanding. The job was on schedule and on budget. Every hiccup, bump and oversight were handled without drama. Nathan knows his business and as he told me one day, "You just plan for there to be problems and you handle it, happens on every project." We could not be happier with the job, would highly recommend!"

FAQs for basement remodeling projects in Lomita, 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.
