AfterConstruction Services in Union City, CA
Most construction headaches in Union City start the same way: a homeowner signs a contract, the crew shows up late or not at all, and the final bill doesn’t match the first quote. The homes here, many built on former bay marsh in the 1960s and 70s, also throw curveballs that out-of-area contractors don’t see coming, from liquefaction-zone soils to groundwater that’s barely below the slab. That’s where we come in. Barrett & Sons Construction is owner-operated, name-on-the-truck, and already familiar with what Union City’s ground and permitting office will ask for before a shovel hits dirt. Call (877) 610-1318 and you’ll talk to a live person, not a voicemail box.

Why Union City Homeowners Choose Barrett & Sons Construction
Tom Barrett started this company in 1998, and his sons run the crews today. That matters in Union City because the person who signs your contract is the same person you’ll see at the lumberyard or the grocery store on Alvarado-Niles Road. We don’t dispatch strangers from a call center. Every crew member who carries the Barrett & Sons name is background-checked and uniformed on every visit.
We’ve done work throughout the flatlands, from the older Decoto district to the tract neighborhoods east of Mission Boulevard. Homeowners in the Alvarado area and the neighborhoods around Kennedy Park have called us for everything from slab repairs to full kitchen remodels. The permit inspector works for you, not for me, which is exactly why we pull permits on every eligible job and make sure inspections get signed. Ask anyone on your street, or look up the license number yourself. Tom publishes his name, his address, and his license number. No mystery there and no franchise gloss.
Construction Services We Offer in Union City
Kitchen Remodeling
A Union City kitchen remodel usually means working within a 1960s or 70s footprint, which brings its own set of framing and electrical surprises. We install KraftMaid cabinetry and Cambria quartz, and every allowance and change order lands in writing before work begins.
Learn more about our Kitchen Remodeling in Union City.
Bathroom Remodeling
Bathrooms in Union City tract homes often sit on slabs, which means moving a drain line is a real conversation about concrete and soil, not a simple reroute. We handle the plumbing, tile, and waterproofing, and we’ll tell you upfront what the ground conditions mean for your budget.

Roofing
Delta winds and bay moisture push water into exterior assemblies faster out here, so we focus on flashing details and proper underlayment, not just shingle speed. We install GAF and CertainTeed products and stand behind the work with a written 90-Day Done Right Promise.

Windows & Doors
Older stucco-over-wood-frame homes in Union City lose a lot of heat through single-pane windows, and retrofitting Andersen or Marvin units means careful envelope detailing so the first big storm doesn’t find a gap. We measure, order, and install with the bay wind in mind.
Fence Installation
Wind off the bay flexes fences in Union City year-round, so posts need real depth and proper anchoring. We build fences that stay plumb through the diablo season, with everything in writing from the first post to the last picket.
Driveway & Pavers
Older concrete slabs here sit on expansive and sometimes damp fill, so a new driveway or paver patio often starts with soil work, not just forms and pours. We carry Belgard and Techo-Bloc pavers and we’ll explain what your specific lot needs before we quote it.
Home Additions & ADU
Adding square footage in Union City means navigating liquefaction-zone geotechnical requirements, which we handle as a matter of course. We pull permits, coordinate the soils engineer, and build additions that pass inspection on the first walkthrough.
Neighborhoods We Serve in Union City
We work across Union City’s 94587 zip code, from the older streets of Decoto to the neighborhoods around Alvarado and the tract homes west of Mission Boulevard. If you’re near Kennedy Park or the area around Union Landing, you’re in our regular service area.

Why Union City’s Climate & Housing Affect Construction
Union City’s flatland neighborhoods were built largely in the 1960s and 70s on former bay marsh, tidal flats, and alluvial fill. The California Geological Survey classifies much of that ground as high liquefaction hazard zone. That’s not a footnote for a contractor working here. That’s the difference between a foundation that holds and one that settles unevenly after the first big quake. Construction projects in these neighborhoods, from slab repairs to room additions, routinely require geotechnical soils reports and engineered foundation solutions that would not be standard in neighboring Fremont’s hillside tracts or higher-ground parts of Hayward.
Parcels near the former Alvarado salt pond margins and bay shoreline sit in CGS-designated Seismic Hazard Zones for liquefaction. Union City’s building department commonly requires a licensed geotechnical engineer’s soils report as a condition of foundation permit issuance. That step can add 4 to 6 weeks before a shovel hits the ground, and it catches homeowners and out-of-area contractors off guard. We set that expectation on day one, not at the permit counter.
The other piece is water. Shallow groundwater tables and bay-influenced soil moisture complicate below-grade work and accelerate concrete deterioration in older slabs. Strong diablo and delta winds off the bay drive moisture into exterior assemblies, which makes envelope detailing and flashing installation especially critical here. A roof or window job that ignores that reality will fail early in Union City.

FAQs About Construction in Union City
A kitchen remodel in Union City typically runs between $38,000 and $85,000, depending on whether you’re keeping the existing footprint, moving plumbing on a slab, and which finishes you choose. Slab work and seismic retrofitting add cost here compared to cities without Union City’s soil conditions. Call (877) 610-1318 for a free written estimate.
Very likely, yes. Union City’s building department commonly requires a licensed geotechnical engineer’s soils report as a condition of foundation permit issuance, especially on parcels near the former Alvarado salt pond margins and bay shoreline. Plan for 4 to 6 weeks of report lead time before permits are ready. We coordinate that process so you don’t have to chase it.
Only if the scope changes, and only with a written change order you sign first. Every allowance, every price change, every adjustment comes to you on paper before work proceeds. No surprise invoices at the end, because that’s not how Tom Barrett has run this company since 1998.
Yes. Permits are pulled and inspections are signed on every eligible job in Union City. The permit inspector works for you, not for me, which is exactly why we want him involved. If a contractor tells you permits are optional here, that’s a red flag with this building department.
A typical bathroom remodel in Union City takes 3 to 6 weeks, depending on whether you’re moving drains in a slab and what custom finishes are on order. Soils and permit lead time can add a few weeks on the front end for larger changes. We give you a schedule in writing before we start, and we stick to it. Call (877) 610-1318 for a precise timeline on your job.
