Remodeling Company in Redwood City, CA
Home renovation in Redwood City means working with homes that span two very different worlds: flat-lot ranchers from the 1940s through 1970s down by the Bay, and steep custom hillside homes in Emerald Hills and Edgewood that sit on Franciscan melange. Gold Star Contractors has served Redwood City since 2012, and we coordinate every trade under one roof so you’re not juggling five vendors while plan-check runs its course. Call (833) 382-8544 for a free estimate on any scope, from a single hillside retaining wall to a full second-story addition.
Why Redwood City Homes Are Different
Redwood City is a built-out infill market. Most of what we do here is not greenfield construction; it’s remodel, addition, detached ADU, and second-story work squeezed onto tight lots under a permitting department that knows every soil type in town. The flats in 94063 and 94065 sit on bay mud and fill, some of it over old salt-evaporation ground near Redwood Creek, which means deeper piers and liquefaction review before you can add square footage. Up in 94062 and the edge of 94061, we’re on steep, slide-prone Franciscan-complex slopes where older un-engineered decks and retaining walls predate modern seismic and slope ordinances. The same “Redwood City” job can need radically different foundations depending on which side of 101 you’re on.
The housing stock compounds it. Post-war ranchers and bungalows hide knob-and-tube wiring, galvanized pipes, and unpermitted past work that the building department will want cleaned up before sign-off. Hillside Eichler-influenced mid-century homes need structural upgrades and additions that respect the original lines. And the climate, famously mild, lets us build nearly year-round, but the wet-dry cycle swells the expansive clay in the hills, so slab and foundation cracks are common. On the wooded hillsides, wildfire WUI and defensible-space requirements now shape exterior material choices and site plans.
Styles & brands we work with







Our Main Redwood City Services
Two services carry most of the phone calls in Redwood City: full general contracting for additions and structural work, and whole-home remodeling inside the existing footprint.
General Contractor in Redwood City
When a Redwood City homeowner adds a primary suite over a 1960s rancher or converts a sloped backyard into a pad-ready ADU site, the first question is usually the same: who’s watching the foundation, the framing, the drainage, and the permits at once? That’s our job. We run soil and slope review, coordinate the structural engineer, pull permits, and sequence every trade so a hillside addition in 94062 doesn’t stall halfway through plan-check. See the full scope on General Contractor in Redwood City.

Home Remodeling in Redwood City
Remodeling in Redwood City often means working inside homes where the walls hide 70-year-old wiring and the foundation has shifted with the clay. We handle kitchens, baths, and full interior renovations as one accountable team, with access to more than 50 manufacturer brands so you’re choosing real materials, not whatever a subcontractor has on the shelf. Details and pricing are on our Home Remodeling in Redwood City page.

Home Renovation in Redwood City

Home renovation in Redwood City is usually less about what you can see and more about what the soils report and plan-check will let you do. On the flats, older ranchers from the 1940s through 1970s often need knob-and-tube electrical brought to code, galvanized lines repiped to copper, and unpermitted past work cleaned up before any cosmetic work starts. In the hills, the same renovation can trigger slope, drainage, and foundation review that a flat-lot job never faces. Because we run the full scope through one team rather than handing you off between trades, nothing gets built before its structural predicate is handled. That’s the core of our Home Renovation work across Redwood City, and it’s why we quote as a general contractor, not as a series of disconnected subs.
Home Renovation Contractors
Signs you need it
If your home has original wiring, cast-iron or galvanized plumbing, past work that was never permitted, or rooms that no longer fit how you live, it’s time to talk renovation contractors.
What it costs in Redwood City
Whole-home renovation in Redwood City typically falls between $45,000 and $130,000 for a full addition-driven scope, with kitchens alone running $14,000 to $45,000.
How we do it
We start with a site walk and structural review, pull the permits, then sequence demo, rough-in, mechanical, and finishes through one project manager so the job never stalls between trades.
Home Renovation Companies
Signs you need it
When a project spans more than one trade and the alternatives are coordinating three or four separate crews yourself, a full-scope renovation company is the right call.
What it costs in Redwood City
Smaller, focused renovations such as one bath start around $5,000, while typical whole-home renovation work lands between $45,000 and $130,000 depending on structural scope and finish level.
How we do it
We specify the brand, manage the install, and stand behind the result, from rough framing through plumbing trim and final paint, with one project lead from first walkthrough to final inspection.
What Home Renovation Costs in Redwood City
| Item | Typical range in Redwood City |
|---|---|
| Kitchen remodel | $14,000 – $45,000 |
| Bathroom remodel | $9,000 – $28,000 |
| Full home addition | $45,000 – $130,000 |
Will Redwood City permitting delay my renovation?
Yes, plan-check can add weeks or months, especially on the hillside lots in 94062 where slope and seismic review is routine, or on flat-lot additions where liquefaction and bay-mud analysis is triggered. We pull permits and manage resubmittals for you.
Can you handle unpermitted past work during a renovation?
Yes, and it’s common in Redwood City’s older ranchers and bungalows. We bring the unpermitted scope up to current code and coordinate with the building department so your final inspection clears. Call (833) 382-8544 for an exact quote on your situation.

What Redwood City Customers Say
"The foundation survey came back dead on. Everything downstream of that being square is the reason the rest of the build went smoothly."
— Megan Gallagher"Allowances in the contract were realistic rather than artificially low to make the bid look good."
— Danielle Vaughn"He was upfront about a soil issue that added cost early rather than absorbing it and surprising us at the end."
