Fast, Reliable Home Remodeling Across Sunnyvale
Home remodeling in Sunnyvale, CA typically costs $14,000 – $45,000 for a kitchen and $9,000 – $28,000 for a bathroom, with permits running through the City’s One-Stop Permit Center on West Olive Avenue. Most full-scope projects here take 6 – 14 weeks from permit approval to final inspection. That’s the honest starting point. If you’re planning work on a 1950s rancher or Eichler-style home anywhere from Lakewood Village to Cherry Chase, call (803) 680-2547 and we’ll walk you through the real numbers before you commit to anything.
We’re Mason Remodeling, and we’ve worked on enough Sunnyvale homes to know exactly where the surprises hide: original subfloors out of level by an inch, framing that predates current load calculations, electrical panels that can’t carry a modern kitchen. Our Home Remodeling team coordinates every Sunnyvale project through our San Francisco Bay Area office, and we give you a written price before any tool comes off the truck.
Why Mason Remodeling Is Sunnyvale’s Preferred Home Remodeling Company
Sunnyvale homeowners tend to ask sharper questions than most. They live in a city full of engineers, project managers, and people who read specs for fun. That suits us. When someone on Oakmead Parkway asks about our structural engineer’s load calculations or why we prefer Schluter strips at every tile-to-floor transition, we have the answer ready and it’s in plain language.
Every crew member who arrives at your Sunnyvale home has been background-checked and identity-verified under the Threshold Standard. That means you get a name and photo before the visit, and a photo ID badge at the door. Not a vague “our guy will be out.” A specific person you can look up before you open the door. For parents home with young kids or older adults in neighborhoods like Ponderosa Park, that’s not a nice-to-have. It’s how the decision gets made.
Isaac Pruett leads our crew, and he holds to the same 365-Day Done Right Promise on every Sunnyvale project: if the work isn’t right within a year of completion, we make it right at no cost. No dispute process. No conditions. Just a written guarantee with real terms.
Styles & brands we work with
Home Renovation in Sunnyvale
Home Renovation in Sunnyvale is rarely a cosmetic exercise, because so much of the city’s housing stock was built in the 1950s and 1960s. Those Eichler-style and ranch homes have charm, but they also hide outdated electrical, unpermitted modifications from decades ago, and framing that doesn’t meet today’s load requirements. What starts as a kitchen refresh often becomes a structural conversation once the first wall opens. A typical Sunnyvale kitchen renovation runs $14,000 – $45,000 depending on cabinet lines, countertops, and whether we’re moving plumbing or opening load-bearing walls.
Bathrooms are the most common renovation we do for Sunnyvale homeowners. Expect $9,000 – $28,000 for a full remodel, with walk-in shower installations at $4,500 – $12,000 and tub-to-shower conversions at $3,500 – $10,000. Older Sunnyvale bathrooms frequently have cast iron drain stacks that have been corroding quietly for 60 years. We inspect before we quote, because that’s the difference between a firm number and a surprise.
Structural Verification First
Before we remove any wall in a Sunnyvale home, our structural engineer reviews the load path. In ranch homes near Manet and Ponderosa, we regularly find that a previous owner notched joists to run plumbing or ducting in ways that would never pass inspection today. We catch that before you spend money on finishes.
Title 24 Energy Compliance
Sunnyvale’s building department enforces California’s Title 24 energy standards on remodeled homes. If you’re pulling permits for a kitchen or bathroom, expect to address insulation, lighting efficiency, and sometimes window upgrades. We budget for this from day one so it doesn’t become a mid-project invoice.
Home Remodeling Companies in Sunnyvale
Home Remodeling Companies in Sunnyvale range from solo contractors to large design-build firms, and the differences matter. Some price low and make it up in change orders. Others never pull permits. Mason Remodeling puts a written price in front of you before work begins, every time. For a Sunnyvale kitchen remodel, that means a line-item budget showing cabinets, countertops, plumbing, electrical, flooring, and labor separately, not a single vague number.
We’ve heard the stories from Sunnyvale homeowners who got burned. A $9,000 “small kitchen remodel” that ended up at $22,000 because the contractor found unpermitted wiring. A bathroom project stalled for nine weeks because nobody filed the permit paperwork correctly. Our job is to make sure you know what’s real before the first nail goes in.
Permit Sequencing Done Right
The City of Sunnyvale’s One-Stop Permit Center is efficient if your paperwork is correct, and painful if it’s not. We sequence permits so rough-in work doesn’t stall waiting for an inspection sign-off. That keeps draw schedules moving and your project calendar honest.
Allowance Management
Cambria, Silestone, Kohler, KraftMaid: these are real product lines with real price differences. We set per-item allowances, not vague “allowance: $10,000” lines that always seem to grow. You pick your slab and your fixtures from vetted, specification-grade options, and you know the number before we order.
Trusted Brands We Service in Sunnyvale
We install and service products from manufacturer lines worth knowing by name: Cambria and Silestone countertops, KraftMaid and Wellborn cabinetry, and Kohler, Moen, Toto, and Grohe fixtures. For homeowners considering prefabricated ADU options, we’ve worked alongside Abodu and Mighty Buildings units and can handle site prep, foundation, and finish work. We keep common replacement parts and matching hardware available for Sunnyvale customers, which means shorter lead times when a fixture arrives damaged or a slab comes in wrong-sized. You won’t wait three weeks for a reordered van top if we can source it locally through our supplier network.

AfterCommon Home Remodeling Problems We See in Sunnyvale Homes
- Out-of-level subfloors in 1950s ranches. On a 1958 ranch in Lakewood Village, we pulled permits for a load-bearing kitchen wall removal and discovered the original subfloor was off by nearly an inch across ten feet. We corrected the subfloor, re-engineered the header with our structural engineer, and still landed inside the original allowance because we had reserved 12% for structural unknowns.
- Title 24 triggers on Eichler-style homes. Those flat roofs and post-and-beam frames aren’t just aesthetic. Opening walls often means adding insulation and upgrading lighting to meet current energy code, and the City of Sunnyvale expects to see that calculation in your permit package.
- Unpermitted work from previous owners. Decades ago, someone added a bathroom or moved a sink without filing anything. When you remodel, you inherit that problem. We scope for it before we quote so you’re not discovering it at demo.
- Panel and service capacity. Many Sunnyvale homes built before 1975 still have 100-amp panels. A modern induction cooktop, double ovens, and a dedicated microwave can push that over the edge. We check electrical capacity during the initial walkthrough.

FAQs About Home Remodeling in Sunnyvale
Yes for any structural change, electrical work, plumbing relocation, or window enlargement. In Sunnyvale, even replacing a water heater requires a permit, and swapping a tub for a shower without one can come back to bite you at resale. Call (803) 680-2547 and we’ll tell you exactly which permits your scope triggers.
Plan on 12 – 16 weeks: 2 – 3 weeks for permit review at the One-Stop Permit Center, 1 – 2 weeks for rough-in inspections, 6 – 8 weeks of construction, and 1 week for final inspections and punch list. Older homes with structural surprises can add two weeks. We give you a calendar during the estimate, and we update it every Friday.
Three things: structural findings once walls are open (rot, out-of-level subfloors, inadequate headers), electrical or plumbing code deficiencies found during inspection, and your own menu choices (upgrading from stock cabinets to semi-custom, choosing a more expensive slab). We write a 12% structural contingency into every load-bearing project so change orders are rare and explained in advance. Call (803) 680-2547 for a scope that accounts for all of it.
Often yes. Eichler-style homes near Cherry Chase and Fairbrae have post-and-beam construction that often means you can open up a kitchen to the living space without removing every wall, because the load is carried differently than in a traditional stud-framed ranch. The catch is that any wall we do touch triggers Title 24 review. We scope it conservatively and verify with our engineer before you sign.
Every line item: demolition, haul-away, framing, plumbing rough-in, electrical rough-in, waterproofing, tile, fixtures (with exact model numbers), vanity, countertop, paint, and final inspection coordination. Nothing says “allowance” without a specific dollar figure attached. Bring us your scope and we’ll price it against ours. Call (803) 680-2547 and we’ll schedule the walkthrough.
