Remodeling Company in Sunnyvale, CA
Home renovation in Sunnyvale means working on 1950s and 1960s ranch houses and Eichler-era builds that were never designed for modern living, let alone Silicon Valley’s expectations. Most of the homes we renovate in 94086 and 94087 still sit on original slab foundations with post-war framing, and the work usually involves opening up closed-off floor plans, upgrading electrical panels for EV chargers and heat pumps, and bringing everything up to current Title 24 energy code. Workshop Contractors has served Sunnyvale since 2011, and we handle the full scope, from structural changes to finish materials, under one contract. Call (844) 384-3361 for a free estimate on your renovation.
Why Sunnyvale Homes Are Different
Sunnyvale’s housing stock is dominated by 1950s-1960s single-story bungalows and Eichler-era ranches, particularly across 94086 and 94087. These homes were built fast during the post-war orchard-to-suburb conversion, and they share a set of renovation realities: slab-on-grade foundations that make moving plumbing expensive, original 100-amp electrical panels that are maxed out, and low-slope roofs that collect water during winter rains. In 94085 and 94089, you’ll find more apartments, condos, and newer high-density infill near the tech campuses, where renovation work skews toward interior remodels and finish upgrades rather than structural change.
The seismic code is a real factor here. Sunnyvale sits close enough to the Loma Prieta fault zone that shear-wall detailing and foundation bolting come up on nearly every structural remodel. That’s not a bureaucratic nuisance; it’s the difference between a house that performs in an earthquake and one that doesn’t. Winter rains also expose drainage problems on flat and low-slope roofs, so any significant renovation should account for water moving away from the foundation. And in the old orchard-tract lots of 94087, the same block can have an original 1950s ranch next to a brand-new three-story build, which means property-line setbacks, height and shadow objections from neighbors, and matching a modern addition to a mid-century slab foundation are routine parts of the job.
Styles & brands we work with







Our Main Sunnyvale Services
Sunnyvale homeowners call us most often about two things: full general contracting for large-scale projects, and comprehensive home remodeling for kitchens, baths, and whole-home upgrades. Here’s what each involves in this city.
General Contractor in Sunnyvale
When a Sunnyvale homeowner is taking a 1950s ranch down to the studs or adding a second story to an Eichler-era lot, they need a general contractor who can manage every trade, every permit, and every material decision without the owner acting as project manager. Workshop Contractors runs the entire job: structural engineering, demolition, framing, rough-in, drywall, finishes, and closeout. Sunnyvale’s permitting process requires detailed plans and Title 24 energy compliance, and we handle that paperwork as part of the scope. Read more about how we run projects here: General Contractor in Sunnyvale.

Home Remodeling in Sunnyvale
Home remodeling in Sunnyvale usually means reworking the original footprint rather than adding to it: removing walls between a galley kitchen and living room, converting a tub to a walk-in shower, or reconfiguring a hallway bath into a primary suite. The mid-century homes here have good bones but awkward layouts and dated systems. We plan the remodel around how you actually live in the house, source the materials from brands we trust, and install everything with our own crews.

Home Renovation in Sunnyvale
Home renovation in Sunnyvale tends to be driven by the gap between what a 1950s or 1960s ranch house offers and what today’s homeowners need: open floor plans, larger kitchens, primary suites, home offices, EV-ready electrical, and better insulation. The mild Mediterranean climate means we’re never waiting out snow, but winter rains on older flat and low-slope roofs, plus Santa Clara County and Valley Water drainage requirements, shape how we sequence exterior work. Most homeowners don’t realize how many systems interact during a full renovation: foundation, framing, electrical, plumbing, insulation, and roof all have to work together, and our job as a Home Renovation general contractor is to make sure they do.
Home Renovation Contractors
Signs you need it
You’re planning multiple changes at once, such as a kitchen remodel plus a bathroom remodel plus new windows, and you need one team coordinating the sequence so walls aren’t opened twice.
What it costs in Sunnyvale
Full-home renovation work in Sunnyvale typically falls between $45,000 and $130,000 depending on how much of the original structure is touched and which finish materials you select.
How we do it
We start with a site walk and scope definition, then produce detailed plans, pull Sunnyvale permits, and sequence demolition, rough-in, finishes, and final inspection so you have one schedule and one accountable team.
Home Renovation Companies
Signs you need it
You’ve gotten bids from trade-specific contractors for different parts of the same project, and every bid assumes someone else is handling the work they can’t see.
What it costs in Sunnyvale
A coordinated whole-home renovation through a single company in Sunnyvale typically ranges from $45,000 to $130,000, with kitchens on the lower end and full structural reconfiguration on the higher end.
How we do it
We take one contract for the entire renovation, source materials across our brand partners, and bring in the right trade at the right time so you’re never coordinating electricians, plumbers, and drywallers yourself.

What Sunnyvale Customers Say
"Framing crew was meticulous and the walls are straight everywhere. Drywall goes on a lot better when the framing is right."
— Holly Quinn"He caught an error in the engineer's drawings before it got framed, which would have been an expensive thing to discover later."
— Maria Martinez"Quiet, polite, worked straight through, was gone in under two hours. My kids were napping and he was careful about it without me even mentioning it."
— Jerome Dawson
