Fast, Reliable General Contractor Across Union City

Hiring a general contractor in Union City means finding someone who knows what a 50-foot-wide lot does to a delivery schedule and why the 1972 building code still matters on a kitchen remodel. Penhallow Remodeling San Jose has been coordinating that work for Union City homeowners with a straight answer on cost, a written price before any tool leaves the truck, and a crew that handles parking, permits, and the neighbor’s fence line without drama. Call (669) 274-2362 and you’ll reach Trevor Nash or one of our schedulers, not a voicemail tree.

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

A garage converted into a guest room and home office

Union City homeowners consistently tell us the same thing: they’ve been burned by a contractor who gave a verbal number, tore out a wall, and returned with a change order the same afternoon. That is exactly the pattern we’re built to break. Every Penhallow project starts with a written price and a written 365-Day Done Right Promise. If something we install fails inside that year, we come back and make it right at no charge. No service fee, no second inspection bill, just the fix.

Trevor Nash has directed remodels across Union City’s flatlands and hills for years, from compact ranch homes near Decoto Road to larger custom builds east of Mission Boulevard. Our crews are background-checked and uniformed, so the person at your door is the same person who stepped out of our truck. We coordinate staging on Union City’s standard 5,000-square-foot lots like we’ve done it a hundred times, because we have. A live person answers our phone 24/7, and that’s not a marketing line. Call at 11 p.m. and you’ll talk to someone who can schedule.

Residential General Contractor in Union City

Residential General Contractor work in Union City typically runs from a $9,000 small bathroom remodel up to a $130,000 home addition, with most kitchen remodels landing between $14,000 and $45,000. What separates a job that finishes on budget from one that spirals is how well the contractor understands the lot, the foundation, and the city’s permitting process before any walls open up. In Union City’s flatlands, that often means a party-wall agreement because older ranch homes were built within 3 feet of the property line.

Foundation and Seismic Check Before Finish Work

Many 1950s and 1960s ranch homes here sit on unreinforced concrete perimeter footings that have settled unevenly in expansive clay. You can see the signs: stucco corner cracks, doors that stick only in summer, tile that shifted within a year of the last remodel. We check for it before we quote, because finding it after demolition adds a week and a number you didn’t agree to. That’s the whole point.

Permit and Party-Wall Coordination

Union City’s 1972 building code still requires written notice to adjacent owners before structural work on a shared lot line. We file that notice, coordinate with the neighbor, and keep copies for inspection. It’s tedious for a homeowner to do it cold. It’s routine for us.

Hire a General Contractor in Union City

A finished backyard cottage with a small covered porch

Hire a General Contractor in Union City when the project involves load-bearing walls, new plumbing runs, electrical work, or anything that touches the foundation. These are the jobs where a wrong guess costs real money and a stop-work order costs real time. On a kitchen remodel, that means coordinating the cabinet lead time with the countertop template with the permit approval, so you’re not living without a sink for three extra weeks because the quartz hadn’t been templated yet.

Access and Staging on Tight Lots

A 50-foot-wide lot on Decoto Road doesn’t have a staging area. We plan the material drops in phases and schedule deliveries so nothing sits on the sidewalk overnight. Blocking a public walkway in Union City will draw a complaint fast, and we don’t make homeowners manage that. The access plan is part of your free estimate, because it affects the price.

The Written Price and the 365-Day Promise

Every quote we hand over in Union City is a written line-item price, not a range. The number on day one is the number on the final invoice unless you change the scope. And every project carries our 365-Day Done Right Promise in writing. If it fails inside a year, we fix it. No invoice, no argument.

Trusted Brands We Service in Union City

We install products from manufacturers that stand behind their work the way we stand behind ours. Cambria and Silestone quartz, KraftMaid and Wellborn cabinetry, Kohler and Moen fixtures, and fencing systems from Ameristar and Jerith when a Union City project calls for a new yard line. We order materials locally where we can and stage them in a way that respects a tight lot. The products we choose have their own warranties that layer over the 365-Day Done Right Promise, so a Union City homeowner isn’t relying on one slip of paper.

Common General Contractor Problems We See in Union City Homes

  • Liquefaction-prone soil under old slabs. West of the Hayward Fault, Union City has areas of bay mud and engineered fill. A 1960s ranch home’s slab may look fine and still need compaction testing before an addition.
  • Missing party-wall notices. The city’s 1972 code requires written notice to adjacent owners before structural work near a shared lot line. Skip it and a neighbor’s complaint can trigger a stop-work order. We file it in advance, every time.
  • Corroded exterior fasteners from morning fog. Union City’s consistent marine layer accelerates rust on metal strapping and fixtures. We spec corrosion-resistant hardware on any exterior or crawl-space work.
  • Unreinforced perimeter footings. Many original ranch homes have no rebar in the perimeter foundation. Cosmetic fixes over an unstable footing are a waste of money. We check first.

Pricing for General Contractor in Union City, CA

Here’s what you’re looking at in Union City, straight:

Project Typical Range in Union City
Kitchen Remodel $14,000 – $45,000
Bathroom Remodel $9,000 – $28,000
Home Addition $45,000 – $130,000

What moves the number: foundation condition, lot access, cabinet line, countertop material, and whether the project touches a shared wall. A small kitchen remodel in flatland Union City tends toward the bottom of that range. A full kitchen with a foundation upgrade and Cambria countertops runs toward the top.
