"Could not recommend this company more. Called during one of the big storms we had this winter after we had several leaks. Many companies weren't bothering to return calls etc. These guys came out pretty quickly and gave us a very competitive estimate. He did great job of walking me through the details of the work they would do and what it would look like etc. Once the work started I was super impressed. The work crew could not have been more polite and accommodating. Very neat. At the same time we had a solar tube installed in my kitchen. Provides so much light. They were great about cleaning up and working around the pets. Bottom line- The roof looks fantastic, I'm not broke cause I paid a very fair price, and next winter it can rain all it wants but my house will be very dry for years to come."

"We had a really great time working with Oren and Michale. From the first time we talked to them to the very end, they were super good at what they do. T hey changed our old-looking house into a new, nice one that feels really welcoming. Our project included complete home remodeling, new roof, solar panels, new elevations for exterior walls, landscaping and hardscaping work. They did a very, very good job making everything look perfect and paying attention to every little thing. I think everyone should use them for their house!"

"Excellent work on the project throughout. Had two huge custom windows with wood trim that needed replacement from wood rot. Also needed to replace a door and fix the flooring around them. Liron and the team did a fantastic job and it turned out better than I expected and on budget."

"Green Planet Remodeling just completed our kitchen remodel and we couldn’t be happier with the results. They were upfront about costs, stuck to the schedule, and the quality of their work was excellent. The design process was collaborative — they really took the time to understand how we use our kitchen and gave us suggestions that made a big difference (hello, hidden spice rack!). They handled everything with professionalism and made what I thought would be a chaotic process feel pretty stress-free. No hidden fees, no runarounds, just good people doing great work!"

"ABC Remodel did a FANTASTIC job. Mr. Orhan Baser and Mr. Richard Betancourt would personally come to review the work and inform their workers what and how they expected the work to be done. But what also impressed me is that both were very kind to the workers but also did not allow for any negative behavior or sloppy work. It was amazing. They took a terminally basically destroyed house and turned it into a home, a palace, an oasis. I could not believe the transformation of the house. I had no experience in remodeling, and with the help of Mr. Baser and Betancourt they would advise in terms of which tiles to use for my needs, appliances, and on top of that, transformed the entry to an upstairs unit to be more private, thus turning the house into two private entries. In addition, I had an official laundry room with sink and all, which before there was none. I was so touched by their care and attention to details as if it was their own home they were remodeling. I would with eyes closed recommend ABC Remodel to anyone who wants quality, on time work. Oh, and they stand behind their work, responding quickly to any requests. I'd do it again. Because quality is rare to find these days, and cheap work is available but the quality, the workmanship is absent. It's a great investment! It's worth every penny!"

FAQs for basement remodeling projects in Santa Clara, 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.
