Why Penhallow Remodeling Is Union City’s Preferred General Contractor Company

Union City homeowners don’t have much patience for vague estimates that change after demolition day. Neither do we. Our General Contractor team works under a specific standard: a written price before any work starts, a real arrival window, and a clean job site every evening. When you call us about a kitchen remodel, a bathroom remodel, or a whole-home project, you’ll hear the same thing every time: we inspect first, price in writing, and never ask you to approve a change without seeing the number first.

Local Union City customers call us when they want a contractor who understands the houses here. The 1960s ranch-style homes near Alvarado-Niles Road have different structural realities than the newer builds east of Mission Boulevard. A contractor who has not opened walls in both will miss things. We have. We look for them before you pay for them.

Response time matters to Union City residents. Scheduling from our San Francisco Bay Area office, we coordinate crews that serve Union City locally, so when you book an estimate, you’re not waiting for a crew from across the Bay. Every technician who walks through your door is background-checked and in uniform. You’ll know exactly who is in your home.

Written Prices and a Written Guarantee

The Kingswell Way has been our operating standard since 2004: say the price before the work, show up in the window we gave, leave the place cleaner than we found it. Our 365-Day Done Right Promise backs that standard. If something fails within a year of project completion, we come back and fix it at no charge. That free return visit is written into your contract, not promised verbally.

Materials Backed by Brands You Know

We install Cambria quartz, which carries its own lifetime warranty alongside ours. We work with KraftMaid and Wellborn cabinetry, Kohler and Moen fixtures, and James Hardie siding. The products behind our guarantee are as solid as the promise itself.

Hire a General Contractor in Union City

Hire a General Contractor in Union City when a project spans multiple trades, or when a permit triggers code upgrades you did not anticipate. Union City’s residential stock was built out primarily between the 1960s and 1980s, and a surprisingly high share of those homes still carry original wiring, aging foundation hardware, and framing that was never designed for modern loads. A general contractor coordinates the electrician, plumber, structural engineer, and county inspector so you don’t have to. Kitchen remodels in Union City typically run $14,000 – $45,000, while bathroom remodels run $9,000 – $28,000. A full home addition starts around $45,000 and can reach $130,000 depending on geotechnical requirements.

Inspection Before Demolition

We don’t start tearing out walls until we’ve inspected what’s behind them. In Union City’s older ranches, that often means we find something the previous contractor missed: undersized framing, outdated wiring, or a load-bearing wall modified without a permit years earlier. We identify it, price it, and get your approval in writing before we touch it.

Written Change Orders, Never Verbal Surprises

If we open a wall and discover a problem, you’ll see a written change order with a specific price before we proceed. No verbal ballparks. No “we’ll figure it out later.” The number you approve is the number you pay.

General Contractor Services in Union City

General Contractor Services in Union City cover the projects that require multiple permits, sequenced trades, and a single point of accountability. Whether you’re remodeling a kitchen in a tract ranch near Decoto, adding a bathroom off a primary suite near Alvarado, or converting a garage into a rental unit, the scope is bigger than any one trade. A garage conversion in Union City typically runs $30,000 – $80,000, and the soft-soil foundation issues in the western flatlands can push costs toward the upper end when engineered footings are required. Window replacement runs $4,500 – $15,000 depending on sash count and corrosion-resistant hardware spec.

Whole Home and Room Addition Work

A whole-home remodel or a room addition in Union City crosses every trade at once: framing, electrical, plumbing, weatherproofing, and final finish work. We sequence those trades so the job moves without gaps. Additions in Union City typically run $45,000 – $130,000, with geotechnical borings and engineered foundation designs adding cost for homes in the western flatlands near the former Alvarado marshlands.

Kitchen and Bathroom Remodeling

Kitchen remodels in Union City are our most-requested service. Homeowners upgrading 1960s-era ranches often discover the original electrical panel cannot carry a modern kitchen load. We account for that in the written estimate before demo starts. Small kitchen remodels run $9,000 – $20,000; full kitchen remodels run $14,000 – $45,000.

Trusted Brands We Service in Union City

We stock and install materials from brands Union City homeowners recognize and trust: KraftMaid and Wellborn cabinetry, Cambria, Silestone, and Caesarstone countertops, Kohler and Moen fixtures, and James Hardie siding. For ADU and prefab-adjacent projects, we’re familiar with factory-built systems from Abodu and Mighty Buildings and can coordinate a general-contractor scope around them. Because we schedule locally and maintain strong supplier relationships, we can turn around material orders for Union City projects faster than a company pulling from out-of-state warehouses. You’re not waiting on a cabinet shipment from across the country when the supplier is already in the region.

Common General Contractor Problems We See in Union City Homes

• Liquefaction-zone foundation surprises in the western flatlands. Homes near the old Alvarado district sit in documented liquefaction hazard and FEMA flood zones. When Alameda County flags a permit for geotechnical borings and engineered foundation designs, the cost and timeline change, and clients who never expected it get a hard lesson. We explain this risk up front and budget for it in the written estimate.
• Salt-laden marine air corroding exposed metal hardware. Union City’s bay-edge position means fasteners, flashing, and structural hardware corrode faster than inland East Bay cities. When we open a wall and find rusted connectors, we spec corrosion-resistant replacements during rough-in, when the cost is a fraction of what a failed repair would cost later.
• Older ranch homes with outdated wiring and undersized framing. The 1960s-through-1980s tract homes that dominate Union City’s housing stock often carry original aluminum branch wiring and framing that does not meet current load codes. A permit inevitably triggers upgrades once the county inspector sees what’s inside. We inspect before we quote so those costs are in the written number, not a surprise after demo.
• Compressed wet-season scheduling for exterior work. Union City’s wet season runs November through March, and the dry window for foundation pours, framing, and exterior work is shorter than it looks. Homeowners who start a project in January without a realistic schedule end up with weather delays. We sequence exterior work around the dry months and plan interior work for the wet ones.
