Why Barrett & Sons Construction Is San Mateo’s Preferred Fence Installation Company
We’re not a franchise dispatching strangers from three counties away. Tom Barrett lives twenty minutes from most San Mateo neighborhoods, and if something’s wrong with a fence we built, he wants to know about it. His sons run the crews, and those crews wear the Barrett & Sons name on their shirts. That matters when a homeowner on Alameda de las Pulgas asks who’s walking their property line.
Our San Mateo customers know our pricing approach before we dig the first post hole. Scope in writing, allowances in writing, change orders in writing. The permit inspector works for you, not for me, and we pull permits on every eligible fence job. That includes the structural engineer’s foundation design the city wants east of 101. We don’t argue with the building department; we design to what they require and tell you the cost up front. Our Fence Installation team has built and repaired fences across every San Mateo zip code, from downtown 94401 to the bayside parcels of 94404.
Our Fence Installation Services in San Mateo
Wood Fence
Cedar and redwood privacy fences are the most common projects we build in San Mateo. The central flatlands are full of 1940s and 1950s ranch homes that need boundary fences replaced after decades of morning fog keeping boards damp through spring. On the hillside lots of 94402, we set posts in 3-foot deep piers with steel brackets so the fence can shift with clay creep without racking the gate frames.
Fence Gates
A gate is only as good as the posts holding it. On bay fill east of 101, we size gate posts with deeper concrete piers and heavier hardware than a standard fence panel requires. Gate frames on soft mud twist when posts heave, and a twisted gate is the first thing a home inspector flags during a sale. We build gates that swing level on day one and stay level.
Privacy Fence
Privacy fences in San Mateo do double duty: they screen the neighbor’s second-story window and they muffle the sound of El Camino Real traffic. We set posts at 6-foot centers instead of 8 when the wind off the bay hits exposed yards in Foster City and the eastern edge of San Mateo. Board spacing, post depth, and hardware all get spec’d for your specific exposure, not a stock drawing.
Aluminum Fence
For homeowners near San Mateo’s downtown, aluminum fence panels around a 1910s Craftsman in 94401 look right without blocking the architecture. Aluminum doesn’t rust like wrought iron, and it weighs less, which matters when we’re working around old lath-and-plaster homes with original foundations we’d rather not disturb.

We carry Ply Gem and Simonton hardware and panels, and we stock common replacement parts locally so San Mateo customers aren’t waiting on a freight truck from Nevada. If you bought a Ply Gem fence from another contractor and need a matching gate or a repair, we can usually source the exact panel profile. Homeowners in Hillsborough and Belmont call us for brand-matched repairs on existing fences, and we keep our parts pricing transparent: you see the material line items before we order anything.
Common Fence Installation Problems We See in San Mateo Homes
- Posts set in bay mud east of 101. Contractors who skip the soils report in 94404 set posts in standard concrete footings that heave and tilt within two seasons. Twisted gate frames and snapped pickets follow. We won’t set a post east of 101 without knowing what’s under it.
- Hillside water pockets in 94402 and 94403. Winter rains sit in subsurface pockets on slope lots, and unsealed post bases rot below grade. The whole fence line sags by summer. We seal post bases and run drainage stone where the grade channels water.
- Missed septic and well setbacks on acreage. A fence line that crosses a septic tank or well head without verifying county setbacks means moving the fence mid-project. That’s a change order the homeowner didn’t budget for. We verify setbacks before we mark the line.
- Undersized gate posts on steep driveways. San Mateo hillside driveways put stress on gate hinges that flatland builders don’t see. A standard 4×4 post set two feet deep fails at the hinge within a year. We use 6×6 posts with through-bolts on any gate wider than four feet on a slope.

What drives the final number? Post depth and pier design change on the east side of San Mateo. Hillside grades in 94402 mean more concrete, more steel, and more labor hours per linear foot. Septic and well setback verification adds a survey cost. Every one of these shows up as a written line item before you sign anything.

FAQs - Fence Installation in San Mateo
Not every fence, but any fence with posts set in the bay mud east of Highway 101 will likely trigger a soils report and a structural engineer’s foundation design. The city’s building department treats soft bay mud as a structural condition, not a formality. Standard spread footings that pass inspection in 94402 two miles west don’t pass in 94404. We handle the soils report, the engineer’s design, and the permit package as one written scope, so you see that cost before we order a single bag of concrete. Call (877) 610-1318 for an exact quote on your property.
San Mateo County requires specific setbacks between fence lines and septic tanks, leach fields, and well heads. If your acreage has a septic system and the proposed fence crosses that setback, you’ll be moving the line, digging new post holes, and paying for it. We verify setbacks with the county before we mark the fence line, so that conversation happens before you sign a contract, not after a crew is standing in your yard with an auger. Estimates are free at (877) 610-1318.
Bay fill is soft, saturated mud with high water tables. A post set in that soil without deep piers and proper drainage will heave and tilt as the ground shifts with seasonal moisture. Hillside clay in San Mateo creeps slowly; bay mud moves more, and it moves unevenly. That uneven movement twists gate frames and snaps pickets within two seasons. We design for it: deeper concrete piers, steel post brackets, and drainage stone around every post east of 101. For a free on-site look, call (877) 610-1318.
Subsurface water pockets. Winter rains collect in pockets on San Mateo’s hillside lots, and unsealed post bases rot below grade within a few years. The fix isn’t just longer posts; it’s sealing the post bases, running drainage stone where the grade channels water, and sometimes notching a rough-in for a future retaining wall. That work adds labor and materials, and it’s exactly the kind of thing a lowball quote leaves out. We put it in writing before we dig. Call (877) 610-1318.
On a hillside lot in 94402, our crew set a 120-foot cedar privacy fence along a steep grade where the original posts leaned 15 degrees from clay creep. We pulled permits, notched a rough-in for a future retaining wall, and used 3-foot deep piers with steel brackets so the fence could move with the soil without racking the gates. The final inspection sign-off came the same day we finished the punch list. For steep grades, we step the panels or rack the rails depending on the slope, and we never leave a gap. That’s the standard, written into every contract. Call (877) 610-1318 to have us walk your slope.
