Remodeling Company in Sunnyvale, CA
Mason Remodeling is a general contracting and remodeling company serving Sunnyvale, CA with written pricing before any work begins and a 365-Day Done Right Promise on every completed job. Sunnyvale homes run the gamut from 1950s Eichler-inspired ranchers with flat roofs and radiant heating to 1990s two-story track homes and a growing number of new ADU conversions. Each era of construction brings different structural quirks, which means the work here rewards a contractor who can diagnose before demolishing. Call (803) 680-2547 to schedule a free estimate.
Why Sunnyvale Homes Are Different
Sunnyvale sits on the floor of the Santa Clara Valley, and the soil here is largely clay-heavy bay fill that expands and contracts with seasonal moisture. Foundation settling is a real thing we see in neighborhoods like Cherry Chase and Serra, especially on post-tension slabs from the 1970s and 1980s. When a homeowner in Sunnyvale wants to open up a load-bearing wall between the kitchen and living room, the conversation almost always starts with a structural engineer reviewing the slab, not just the framing above it. That is not true everywhere, but it is the norm here.
Permitting matters too. The City of Sunnyvale has adopted California’s 2022 building codes with local amendments around energy compliance, and CalGreen requirements are enforced on remodels that touch more than a certain percentage of the home. If your project changes the building envelope, plan on a Title 24 energy report. We handle this paperwork for you, but it affects timeline and cost. HOA approvals are also common in the city’s newer planned communities, particularly for anything visible from the street.
Styles & brands we work with
Our Main Sunnyvale Services
Most Sunnyvale homeowners call us about general contracting and bathroom or whole-home remodels, and each of these has its own dedicated Sunnyvale page with detailed local pricing and scope. Here is what each one involves in this market.
General Contractor in Sunnyvale
Kitchens top the list for general contracting work in Sunnyvale, where the stock of mid-century homes often has galley kitchens that feel cramped by modern standards. The job typically involves removing a non-load-bearing divider, reconfiguring the layout, and coordinating subcontractors for electrical, plumbing, drywall, and cabinetry. Given the slab foundations in much of the city, relocating a sink or range often requires trenching concrete, which is predictable but labor-intensive. Our crews plan for this from the first site visit so your written price reflects reality. Read more on the General Contractor in Sunnyvale page.
Bathroom Remodeling in Sunnyvale
Bathroom remodels in Sunnyvale frequently involve homes with original 1960s or 1970s cast-iron drain lines that have corroded over decades. If the line is failing, the remodel scope expands to include a drain replacement before tile work begins. Walk-in showers and tub-to-shower conversions are two of the most common requests, especially in the city’s ranch-style homes where the original hall bath is small. We provide a written price on every bathroom remodel before any tools are unpacked. See Bathroom Remodeling in Sunnyvale for full scope and pricing.
Home Remodeling in Sunnyvale
Whole-home remodels in Sunnyvale usually mean bringing a 1950s or 1960s house up to current standards: new electrical panel, updated HVAC, opened sightlines, and modern finishes throughout. These jobs often run alongside an ADU or garage conversion because Sunnyvale’s lot sizes, particularly in areas like Lakewood Village, can accommodate a rear unit. The permitting process for a whole-home remodel here takes longer than a single-room job, and we build that into the schedule up front. The Home Remodeling in Sunnyvale page covers the details.

Brands We Service in Sunnyvale
We routinely install and service specification-grade materials from brands like KraftMaid and Kohler in Sunnyvale homes, drawing on our material partnerships rather than whatever is available at a big-box store this week. Common finishes and replacement parts are stocked locally in our Bay Area warehouse, which keeps most small material gaps to a few days rather than a few weeks. See our brands for the full list.
