Fast, Reliable Fence Installation Across San Martin
Fence installation in San Martin, CA typically costs between $3,500 and $9,000 for a standard residential run, and most projects on acreage properties take one to three weeks once permits clear Santa Clara County. We schedule work in San Martin every week, and our crews know the difference between a boundary fence on a quarter-acre lot and a 600-foot perimeter run around a horse property. If you’re researching what your fence will actually cost here, call (877) 610-1318 for a line-item quote built for your parcel, not a national average.
Why Barrett & Sons Construction Is San Martin’s Preferred Fence Installation Company
Tom Barrett started this company in 1998, and his sons run the crews that show up in San Martin. That matters because the same person who shakes your hand at the estimate is the one who walks the line with you before post holes get dug. We pull every permit through Santa Clara County before setting a single post, and every change to your scope arrives as a written change order with a price attached. No surprises when the bill comes.
San Martin homeowners tell us the same thing, over and over: another contractor quoted one number on the phone, then handed them a different invoice at the end. That’s why our quotes include the allowance in writing, the setback in writing, and the inspection schedule in writing. We published Tom’s name, address, and license number so you can verify us before you sign anything. A live person answers our phone around the clock, and our crews are background-checked and uniformed.
Our Fence Installation Services in San Martin
Wood Fence
Wood fencing works hard on San Martin acreage. Redwood and cedar hold up well in the valley’s Mediterranean climate, but only when posts are set deep enough to survive the expansive adobe clay beneath this part of Santa Clara County. We size post depth and concrete collars for the soil’s wet-dry movement, not just the wind load. A standard 6-foot redwood privacy run in San Martin usually falls between $3,500 and $7,000 for a 150-foot stretch, though larger parcels push higher.

Privacy Fence
On properties off Foothill Avenue or running back toward San Martin Avenue, a privacy fence often doubles as a windbreak and a horse barrier. We route alignments around septic leach fields and wellheads per county setbacks, and we build gates wide enough for tractors and trailers. When your parcel sits within the FAA Part 77 airspace envelope around San Martin Airport, we check whether a tall privacy screen needs a federal airspace determination before the county will even look at the permit.

Fence Gates
Gates are where cheap fences reveal themselves. A sagging gate six months after install is the telltale sign someone hung a big panel on small posts. For agricultural and ranch gates on San Martin parcels, we spec heavier posts, adjustable hinges, and drop rods that hold up to clay movement and dry-season dust. Whether it’s a 4-foot walk gate or an 8-foot equipment gate, we build it to open true in year three, not just on day one.

Chain Link and Aluminum Fence
Not every San Martin property wants a solid wood screen. Chain link keeps dogs contained and horses visible, and it handles the valley’s clay heave better than most materials when posts are set correctly. Aluminum fence gives you the look of wrought iron without the rust, and on parcels near San Martin Avenue with vineyard frontage, it holds up well against irrigation overspray. Aluminum runs typically land between $4,000 and $10,000 on larger lots.

Trusted Brands We Service in San Martin
We install and service fence systems from manufacturers whose specs we can stand behind. On San Martin jobs, we work with Simonton and Ply Gem vinyl and aluminum product lines, and we keep common parts and hardware on hand so a gate repair doesn’t stall out waiting on a shipment. For coastal-influenced parcels in the southern end of the 95046 ZIP, where morning fog off the Pacheco Pass meets salt air from Monterey Bay, we recommend aluminum over steel for longevity.
Common Fence Installation Problems We See in San Martin Homes
- Posts heaving out of expansive adobe clay. The Pacheco-series soils under much of San Martin swell in winter and shrink hard in summer. Posts set at shallow depth or without proper concrete collars lean within two wet-dry seasons, and we rebuild more of these than we install new on older properties.
- Fences placed inside county setback envelopes. Santa Clara County Environmental Health enforces minimum distances from septic leach fields and wellheads. A fence that looks fine on a plot map can trigger a permit stop if it sits 40 feet from a leach line when the county requires 50.
- Winter starts that stall in saturated clay. A long boundary run begun in November hits rain-saturated soil, and the excavation turns unworkable. We schedule grading and post-setting windows against the valley’s dry season, and we write a re-mobilization line into any quote that might stretch past November.
- Airport airspace surprises on tall structures. San Martin Airport (E16) sits right in the community. An 8-foot gate or tall corner post near the airport’s approach surface can need an FAA Part 77 determination before the county issues the building permit. Out-of-area contractors miss this until the permit gets kicked back.

FAQs - Fence Installation in San Martin
In San Martin, septic leach fields and private wells carry mandatory horizontal setbacks enforced by Santa Clara County Environmental Health, and a fence post, gate footing, or any permanent structure must stay clear of those envelopes, typically 50 feet from a leach field and a set distance from the wellhead depending on parcel specifics. We pull the county’s property records before we draw any fence line, and if a planned alignment comes within the setback, we adjust the route in the written scope before you ever see a change order. Call (877) 610-1318 and send us your parcel number; we’ll verify the setbacks on your lot for free.
Yes, in some cases a fence or gate structure near San Martin Airport needs an FAA Part 77 airspace determination in addition to the Santa Clara County building permit, especially for taller gates, corner posts, or any run that encroaches on the airport’s protected airspace surfaces. We check the parcel against the E16 obstruction overlay before we quote, and when the FAA determination is required, we build the timeline for it into your schedule so the county permit doesn’t stall. Call (877) 610-1318 and we’ll check your parcel at no charge.
Because the valley floor under San Martin sits on expansive adobe clay that swells when wet and shrinks when dry, and a fence line that ignores grade or drainage will heave, lean, or channel water into your neighbor’s pasture within two seasons. We include the grading and drainage scope whenever the parcel’s slope, soil, or runoff pattern demands it, and we put that number in writing before we dig. If your property has a swale, seasonal creek, or heavy clay lens, it’s in the quote.
The underground conditions and setback complications, specifically the exact locations of septic leach fields, wellheads, and any unmapped agricultural drainage tiles from decades of farming use on these parcels. We scope a fence on acreage by walking the land first, not by assuming the plot map is complete, and our quotes include an allowance for locating buried lines before excavation begins. Tom’s rule is simple: the allowance that isn’t on paper is a surprise waiting for a date, so we put it on paper.
We treat the fence as a single project with two legal touchpoints, the county building inspection for structural and setback compliance on the residential portion, and any agricultural or environmental condition the county attaches to the ranch or farm portion, and we manage both tracks in one schedule. Every inspection gets signed before we call the project done, and the 90-Day Done Right Promise means if something’s not right after final sign-off, one call brings Tom back. Call (877) 610-1318 to schedule your free estimate, and we’ll walk your San Martin parcel with you before any number goes on paper.
