Fast, Reliable Home Remodeling Across Sunnyvale
Home remodeling in Sunnyvale runs $14,000 – $45,000 for a typical kitchen and $9,000 – $28,000 for a bathroom, with whole-home and addition work scaling from there. But the number that matters more is what the job costs in ten years. We’re Seaside Contractors, led by Glen Sorrento, and we’ve built our Sunnyvale work around a simple truth: this city’s bay-driven salt air decides what materials survive, and most estimates ignore it. Call (833) 589-8103 for a free estimate built for Sunnyvale’s actual conditions, not a generic spec sheet.

Why Seaside Contractors Is Sunnyvale’s Preferred Home Remodeling Company
Sunnyvale homeowners tend to research harder than most. They know brand names, they ask about substrates, and they want one contractor who can speak to every trade. That matches how we work. Our Home Remodeling team manages the full scope, from structural work through finish selection, without handing you off to a different sub for each phase.
We’ve worked across Sunnyvale’s 94085, 94086, 94087, and 94089 ZIP codes long enough to know that a house three blocks from the bay ages differently than one east of Wolfe Road. The marine layer pushes salt air through the 94085/94089 corridor, and it shows up in corroded fasteners, chalked exterior finishes, and failed low-slope roof penetrations on houses that otherwise look fine. We plan for that before the first cut.
Glen Sorrento built Seaside Contractors around a single point of accountability. One contractor. Every trade. From blueprint to final walkthrough, you’ll work with one team that knows the entire project, not a patchwork of subs who’ve never met each other. That’s how a remodel in Sunnyvale stays on schedule when a tree ordinance review delays demo or a winter storm hits the roof mid-project.
Styles & brands we work with







Luxury Home Remodeling in Sunnyvale
Luxury Home Remodeling in Sunnyvale is a different discipline than it is inland. On the Eichler and mid-century ranch lots of Birdland and Cherry Chase, the budget goes first into what you can’t see: marine-grade flashing, stainless hardware on every exterior opening, humidity-stable cabinetry, and waterproofing systems that hold up against bay air. Then comes the finish work. A luxury kitchen in Sunnyvale typically runs $14,000 – $45,000, and that range reflects the coastal-spec materials as much as the countertops. You’ll choose from Cambria, Silestone, and Caesarstone, with KraftMaid or Wellborn cabinetry spec’d to the moisture conditions of the house.
Coastal-Spec Kitchen Build
We start with the opening, not the cabinet face. Door and window hardware goes stainless, not zinc. Joints get sealed before finish carpentry closes them. The cabinetry gets a humidity-stable finish so the boxes don’t swell in that bay-driven moisture.
Primary Bath Retreat
A luxury primary bath in Sunnyvale runs $9,000 – $28,000. We lean on Schluter waterproofing behind the tile, Toto or Kohler fixtures, and a walk-in shower built with the slope tolerances that make a glass enclosure seal correctly. The tile is the last decision, not the first.
Full Home Remodel in Sunnyvale
A Full Home Remodel in Sunnyvale usually means one of two things: a scrape-and-rebuild on an original Eichler lot, or a room-lift that strips a mid-century ranch back to the studs and rebuilds it with modern systems. The cost lands between $45,000 and $130,000 for an addition, and a whole-home scope often starts with foundation and structural upgrades before any finish work. Sunnyvale’s older wood-frame stock carries decades of deferred maintenance, and the flat or low-pitch roofs on those mid-century homes need replacement as part of the scope, not as a change order later.
Second-Story Additions
On a Birdland ranch lot, going up is often the only path to square footage. We handle the structural load path, sheer, and foundation tie-downs before the framing starts. The city’s lot coverage and massing review means the drawings have to be right the first time, not revised on the fly.
Whole-Home Mechanical and Envelope
When walls are open, this is the window to fix what the last remodel skipped: re-flash every opening, replace failed window frames with PGT or Therma-Tru units, and bring the roof assembly up to a coastal standard. We’ll match the material to the project, not to a sales flyer.

Trusted Brands We Service in Sunnyvale
We stock and install across 50+ vetted brand lines, which means a Sunnyvale project doesn’t stall waiting for parts. On the plumbing side, we work with American Standard, Toto, and Sterling; for waterproofing, Schluter is our default behind tile and wet areas. If you’re swapping a tub for a walk-in shower in a 94087 condo or re-finishing a master bath in Cherry Chase, we can quote the fixture package with real lead times, not a catalog guess. The brand breadth also means we can value-engineer a phase without switching contractors, a useful lever when a tree-preservation review eats into the original draw schedule.

AfterCommon Home Remodeling Problems We See in Sunnyvale Homes
- Salt-corroded fasteners on exterior openings. Standard galvanized or zinc hardware pits and seizes within a few years of bay air moving through the 94085/94089 corridor. We spec stainless or hot-dip hardware on every exterior door, window, and railing install, and we note the price gap in the line item.
- Flat and low-pitch roof failures on mid-century stock. Eichler and ranch homes in Sunnyvale carry roofs that winter storms push water across slowly. The failed sealant and underlayment that an inland-spec roof would tolerate leaks here because the rain sits longer on the low slope.
- Tree ordinance surprises on large lots. Decades-old heritage oaks and redwoods on Birdland and Cherry Chase lots are protected under Sunnyvale’s tree ordinance. Removal needs a permit and often a replacement plan, and the preservation review can delay demo. We run the tree check before the scope is priced, not after.
- Interior moisture fighting the old materials. A 1962 ranch with sound framing but chalked exterior hardware tells you the moisture got in somewhere. We trace the path from the envelope inward before we close any wall.
Pricing for Home Remodeling in Sunnyvale, CA
The cost difference between an inland-spec job and a coastal-spec job in Sunnyvale is real, and it’s honest to show it in the numbers. Below are the ranges we’re quoting for Sunnyvale work across the most common scopes.
| Project | Sunnyvale Price Range |
|---|---|
| Kitchen Remodel | $14,000 – $45,000 |
| Bathroom Remodel | $9,000 – $28,000 |
| Roof Replacement | $8,000 – $20,000 |

| Countertop Installation | $2,000 – $6,500 |
Those ranges reflect real material choices. The low end uses value-engineered fixtures and inland-standard hardware where the exposure is minimal. The high end is the coastal spec: stainless fasteners, marine-grade flashing, Schluter waterproofing, and premium cabinetry from KraftMaid or Wellborn. The cheap spec costs less up front and more within a decade. Call (833) 589-8103 for a written line-item quote, free, with the hardware and sealant spelled out by name.

FAQs About Home Remodeling in Sunnyvale
The marine layer pushes salt-laden air through Sunnyvale’s 94085 and 94089 corridor, so exterior hardware, flashing, and sealants have to be coastal-spec to survive. That means stainless fasteners instead of zinc, marine-grade roof penetrations, and humidity-stable cabinetry. The material premium is typically 10 – 20% over an inland-spec job, and skipping it costs more when the pitted hardware fails inside a decade. Call (833) 589-8103 and we’ll show you both spec levels line by line.
Yes. Sunnyvale’s tree ordinance protects heritage oaks and redwoods, and removal requires a permit plus a replacement plan in most cases. The review can affect lot coverage and setback decisions, so it needs to run before demo is priced. We handle the arborist report and the city filing as part of the scope. Call (833) 589-8103 if you’re planning around a protected tree.
A fixed line-item quote that names materials, hardware grade, waterproofing methods, and the permit path. Sunnyvale’s tree and lot coverage reviews make vague allowances dangerous. We write every quote with the coastal spec spelled out: stainless hardware on exterior openings, marine-grade flashing on roof penetrations, and the exact cabinetry and countertop lines. No change orders for things a competent estimate should have caught. Call (833) 589-8103 for a free written estimate.
Low-slope roofs hold rainwater longer than steep pitches, so failed sealant and underlayment have time to leak. Sunnyvale’s rain concentrates from November through March, and the same roof on a steeper pitch in Cupertino would shed water faster. The fix is re-flashing every penetration and re-doing the underlayment to a coastal standard, plus a roof assembly rated for the low slope. That’s an $8,000 – $20,000 replacement scope. Call (833) 589-8103 for a roof inspection on your Sunnyvale home.
Yes. Electrical, plumbing, structural, and waterproofing work needs inspection sign-off before drywall closes. In Sunnyvale, the tree ordinance can also add a site review before exterior work begins. We schedule inspections and walk them with the inspector. If a wall closes before sign-off, you own the rework. Call (833) 589-8103 to scope your Sunnyvale remodel correctly from the start.
