"After they redid our counter tops and island, we had them paint out cabinets and build shelves up to the ceiling. The communication was on point this time and the results speak for themselves. Would definitely recommend them to anyone for any home project. "

"We hired Sam for several drywall jobs, including one emergency repair and a major remodel of two rooms. Sam was always professional, friendly, and pleasure to work with. He took exceptional care to not scratch our floors and pricing was always fair. On one occasion, there was a miscommunication regarding scope of work. Sam immediately took responsibility and completed the additional work, including purchasing the supplies out of pocket. We look forward to continuing to work with Sam and highly recommend him. :-)"

"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."

FAQs for basement remodeling projects in Spring Valley, 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.
