Remodeling Company in Union City, CA
Remodeling in Union City means working with homes built mostly from the 1950s through the 1990s, on flat lots with clay soil that shifts in wet winters and bakes hard through dry summers. That combination drives most of what we see here: hairline stucco cracks at door corners, doors that stick after the ground moves, and bathrooms that were original to the house and show their age. Sawyer Remodeling handles the planning, permits, and build for Union City projects, with a written price before any work starts. If you’re considering a remodel here, call (254) 272-5876 for a free estimate.
Why Union City Homes Are Different

Most Union City homes fall into three eras: post-war ranchers from the 1950s and 60s, boom-built two-story homes from the 1970s and 80s, and a strip of newer construction along the Union City Boulevard corridor and near the BART station. The older stock has real character, but it also has the wiring, plumbing, and foundation quirks that come with 50 to 70 years of Bay Area weather.
Two things reliably shape Union City remodels. The first is drainage. The flat terrain throughout the Alvarado, Decoto, and Seven Hills neighborhoods means water moves slowly, and any addition or patio that interrupts the grade needs a thoughtful drainage plan so the backyard doesn’t turn into a bowl every January. The second is the soil. Union City sits on a mix of clay soil that expands when it is soaked and contracts as it dries. We account for that on every foundation, driveway, and addition we build. The city permits through the Building Division, and some HOA communities, particularly in the hills, add a second layer of approval. We pull permits and manage that process as part of every project.
Styles & brands we work with







Our Main Union City Services
Union City homeowners call on us for three jobs more than any others: full general contracting when multiple trades need to move together, bathroom remodels when an original hall bath finally gives out, and whole-home renovations when a family is ready to bring an older house up to modern standards. Each service has its own dedicated Union City page with pricing, process, and what to expect.
General Contractor in Union City
Most remodels touch four trades at once: framing, plumbing, electrical, and tile. A general contractor keeps those trades sequenced and accountable, which matters more on Union City’s older homes, where every wall opened up tends to reveal something the blueprints didn’t include. From that point, the job either stalls or keeps moving depending on who is running it. We pull permits, schedule inspections, and keep the project moving while you get photo updates before and after each phase. Learn more on our General Contractor in Union City page.

Bathroom Remodeling in Union City
Union City’s 1960s and 70s bathrooms are the ones we replace most: four-foot by five-foot compartments with a tub, a pedestal sink, and no exhaust ventilation to speak of. Mold at the window line and tile joints that have failed are common, and once the waterproofing is compromised, a surface refresh is not enough. We install proper waterproofing, vent fans, new shower pans, and Schluter edge trim (the metal strip that waterproofs where your tile meets the floor) so the work lasts. Pricing and process are on our Bathroom Remodeling in Union City page.

Home Renovation in Union City
A whole-home renovation in Union City often means moving walls in a ranch, adding a second bathroom where a closet used to be, or reworking a kitchen that opens onto a family room so the flow matches how the family actually lives. Those projects span structural changes, new stairs, flooring throughout, and finished trim, and they take the longest and test the sequence of the schedule the most. We write the scope, get the price approved in writing, and run the job under The Relay Visibility Guarantee. See our Home Renovation in Union City page for the full breakdown.
