Old fence leaning, rotting, or past its prime? We install cedar, redwood, and pine fences that stand straight through Bay Area winters and clay-soil ground movement.

Wood fence installation in Union City involves setting posts in concrete, attaching rails, and securing boards to create a finished fence line - most residential jobs take one to three days from start to finish. UC Union City Fences handles the full project: measuring, permitting, installation, and cleanup, so you get a fence that is straight, solid, and legal from day one.
Union City homeowners choose wood fencing for its warmth, versatility, and natural look that vinyl and metal simply cannot match. Whether you want a classic picket fence in the front yard or a full-height privacy fence in the back, wood can be cut, shaped, and finished to fit your property exactly. The key is choosing the right wood species for this climate and making sure the posts are set deep enough to stay put through our wet winters.
Our crew has worked on wood fences all across Union City and the East Bay. We know the soil conditions, the permit requirements, and which materials hold up best when the marine layer rolls in every morning from spring through early summer.
Push gently on each post. If any rock or lean noticeably, the base has likely rotted or the footing has shifted - common in Union City's clay-heavy, moisture-prone soil. A leaning post puts stress on the whole fence and can bring down a section in a strong windstorm.
Run your hand along the bottom of boards and posts near the ground. Spongy, flaking, or dark-discolored wood is rot - and it spreads. In Union City's damp coastal climate, rot tends to start at post bases and moves up faster than most homeowners expect.
Some graying is normal as wood weathers, but boards splitting along the grain or pulling away from rails mean the wood is breaking down. Large gaps also reduce the privacy and security your fence is supposed to provide - at that point, replacement makes more sense than patching.
California law requires specific fencing around swimming pools for child safety, and Union City enforces these requirements. If you are adding a pool or an accessory dwelling unit, a new or upgraded fence is often required before the city will approve the project.
We install all standard wood fence styles - board-on-board, shadow box, picket, and split-rail - as well as custom configurations for unusual lot shapes or specific HOA requirements. For homeowners who want maximum backyard privacy, our privacy fence installation service builds full six-foot panels with no gaps. If you like the look of wood but want zero maintenance, we can also walk you through our vinyl fence installation options as a comparison.
Every wood fence we build includes concrete-set posts, pressure-treated lumber for ground contact where needed, and a final walkthrough with you before we leave. We handle permit applications with the Union City Building Division and haul away all debris and old fencing when the job is done.
Ideal for homeowners who want complete privacy and a clean, finished look on both sides.
A classic front-yard option that adds curb appeal without blocking sightlines from the street.

Heavy-duty hinges and latches matched to your fence style, built to last through daily use.
We take out the existing fence and haul everything away before the new installation begins.
Union City sits at the eastern edge of San Francisco Bay, and that location shapes how wood fences perform here. The marine layer rolls in regularly from spring through early summer, keeping air humidity elevated for months at a time. That persistent dampness accelerates rot and warping in wood that is not installed correctly or sealed after the job. We recommend cedar or redwood for every Union City project because their natural oils resist moisture without chemical treatment - a detail that matters a lot more here than it would in a drier inland city. We also serve neighboring Fremont and Newark, where the same Bay-area soil and climate conditions apply.
The other local factor that matters is soil. Much of Union City sits on expansive clay, which swells when wet and shrinks when dry. That seasonal movement can push fence posts out of plumb over time if they are not set deep enough or anchored in concrete. Our crews set posts deeper than the standard minimum and use a concrete mix suited to clay-heavy ground, which is why our fences stay straight through multiple wet and dry seasons. We also know Union City's permit process well - we have pulled permits through the Union City Building Division many times and handle all the paperwork without passing that burden to you.
We respond within 1 business day to schedule a free on-site estimate. We will ask a few basic questions upfront - fence length, height, and whether there is an existing fence to remove - so we can give you an accurate written quote during the visit.
We walk your property, measure the fence line, and give you a written quote that breaks down materials and labor. If a permit is required, we submit the application with the Union City Building Division and keep you updated on approval timing.
The crew marks post locations, digs holes, and sets posts in concrete. Posts need time to cure - often overnight - before rails and boards are attached. Most residential fences are complete in one to three days total.
When the fence is complete, we walk the line with you - checking that posts are plumb, the gate swings freely, and no boards are already bowing. We haul away all scrap wood, old fence materials, and concrete debris before we leave.
We respond within 1 business day - no obligation, no pressure. After you submit, someone from our office will call to schedule a free on-site estimate at a time that works for you.
We hold a valid California contractor license - you can verify it in minutes on the CSLB website. Every job is fully insured, which means you are protected if anything goes wrong on your property. We never subcontract to unlicensed crews.
We recommend cedar and redwood for Union City projects because they naturally resist the moisture and insects common to this climate. We explain the trade-offs between species clearly so you can choose what fits your budget and how long you want the fence to last.
We pull building permits from the Union City Building Division before any work starts. You never have to deal with city paperwork or worry about a fence that is not legally compliant. This matters if you ever sell your home - an unpermitted fence can create complications at closing.
Every post goes in concrete, set at depths calibrated for Union City's expansive clay soils. This is the difference between a fence that stays straight for 15 years and one that leans after the first wet winter. We set posts the right way because this is where we work.
These are not marketing claims - they are the specifics we back up on every job. The American Fencing Association sets professional installation standards that guide our work on every project. If you have questions about any of them, call us and ask directly.
