Whole-Home Remodels in the San Francisco Bay Area
Whether you’ve purchased a Bay Area fixer-upper or are ready to fully transform your existing home, 4Sigma manages the entire process—from initial design and permitting through every phase of construction. We coordinate all trades, handle all permits, and keep your project on schedule so you can focus on the vision, not the logistics.
What’s Included in a Whole-Home Remodel
Floor Plan & Structural Work
Open up living spaces, add a bedroom, reconfigure layouts. We work with structural engineers for wall removal, beam installation, and second-story additions.
Kitchen Remodel
New layout, cabinets, countertops, appliances, tile, plumbing, and electrical—all coordinated within your whole-home timeline.
Bathroom Remodels
Primary suite, guest baths, and powder rooms—all updated to a cohesive design throughout the home.
Flooring
Hardwood, engineered wood, tile, LVP—we install new flooring throughout or refinish existing hardwood to match new additions.
Electrical & Plumbing Upgrades
Panel upgrades, recessed lighting, EV charging rough-in, smart home pre-wiring, whole-house repiping, tankless water heater installation.
Interior Finish Work
Fresh paint, new baseboards and trim, interior doors, and hardware—the details that make everything feel complete.
Why a Single General Contractor Matters
Whole-home remodels involve dozens of decisions, dozens of people, and months of work. Homeowners who manage their own subcontractors often face scheduling conflicts, permit delays, cost overruns, and quality gaps. 4Sigma acts as your single point of accountability—one contract, one project manager, one construction schedule.
