AfterFast, Reliable Fence Installation Across San Mateo
Fence installation in San Mateo typically runs $3,500 to $9,000 for a standard residential project, and the two factors that move that number most are post footings and material spec. East of Highway 101, the bay mud requires deeper embedment and often a geotechnical review before we dig. West of El Camino Real, the soil is more predictable but the seismic proximity to the San Andreas Fault changes how we brace and anchor. We know both sides of San Mateo because we work both sides every week. Call (470) 298-9650 and we will put a written price in front of you before any post hole is dug.
Why Rowan Construction Group Is San Mateo’s Preferred Fence Installation Company
Founded in 2007, Rowan Construction Group has delivered over 4,000 projects, each one with a written price before work started and a documented record when the crew left. That discipline matters in San Mateo, where a fence is not just a boundary line. It is a structural decision affected by liquefaction zones, marine fog, and fifty-year-old housing stock that was never designed for what the Peninsula has become. Grant Rowan built the company on a simple rule: name the number, write the scope, sign the change order before any change happens. Homeowners in Baywood, Beresford, and Shoreview have seen that rule hold true.
Our crews are background-checked and uniformed. A live person answers the phone 24/7. Every visit includes a documented photo record, so you see the condition of your posts and footings before we touch them, and you see the finished work after we leave. We do not ask you to trust a handshake. We hand you the file.
Our Fence Installation Services in San Mateo
Wood Fence
A wood fence in San Mateo means redwood, almost always. In Baywood and Beresford, the original ranch homes from the 1940s and 1950s were built with redwood framing and redwood fences, and homeowners today want the same look. The problem is the fog. North-facing sections that stay shaded by mature oaks and eucalyptus never fully dry, and that persistent marine moisture rots untreated pine and fir from the base up within a few years. We specify clear-heart redwood for the pickets and pressure-treated or steel-reinforced posts for the structure. A typical wood privacy fence in San Mateo runs $3,500 to $9,000 depending on linear feet, post replacement, and whether the old fence has to be hauled off.
Chain Link Fence
Chain link does the job where security matters more than appearance: side yards, utility enclosures, and commercial perimeters. The failure point in San Mateo is always the hardware. Standard galvanized posts set in bay mud rust through within five to ten years because the soil holds salt from the Bay’s tidal influence and the fog keeps the metal damp. We use hot-dip galvanized posts and stainless hardware for any chain link fence east of 101. It adds modest cost and adds decades to the fence’s life.
Vinyl Fence
Vinyl fence installation in San Mateo runs $3,500 to $9,000. Vinyl handles the marine layer better than most wood species because it does not absorb moisture or rot. The catch is the foundation. Vinyl panels are lighter than wood, which means a shallow footing will let the whole run shift when the bay mud heaves during the winter groundwater rise. We set vinyl posts in concrete footings dug to the depth the soil requires, not the depth that is fastest. On the east side of San Mateo, that often means 30 inches or more.
Aluminum Fence
Aluminum fence installation in San Mateo runs $4,000 to $10,000. Aluminum costs more than chain link up front and lasts far longer in the salty air, which is why more homeowners in Shoreview and the San Mateo Park area are choosing it for street-facing fences. The panels are powder-coated, so the finish does not peel the way painted steel does. We use aluminum posts with concrete footings sized for the wind load off the Bay, and we seal every joint against moisture intrusion. The cheap inland spec uses standard steel brackets that will be rust-stained within five years. We do not install that spec here.
For fence repair, Fence Installation is only half the job. Most of the calls we take in San Mateo are for fences that are still standing but failing: rotted post bases, leaning sections, gates that no longer latch. We will tell you honestly whether a repair buys you five more years or whether the structure is gone and replacement is the cheaper path over a decade.

BeforeAfterTrusted Brands We Service in San Mateo
We work with materials from fifty-plus vetted brands, which means the written quote reflects honest cost rather than whatever the supplier had on the shelf. For San Mateo fence work, we specify hardware and coatings that survive the Bay-side salt and fog. We have installed and repaired fences from manufacturers including Abodu, Cover, and Dvele where the property involved a prefab or panelized structure. The brand matters less than the material spec underneath it. We will show you both in the written scope.
Common Fence Installation Problems We See in San Mateo Homes
- Steel post rust-through in bay mud: Standard galvanized hardware buried in the saline soil east of 101 corrodes in five to ten years. We specify hot-dip galvanized posts and stainless fasteners on every Bay-side fence.
- Post heaving from liquefaction-prone fill: The bay mud in neighborhoods east of the Caltrain corridor shifts with seasonal groundwater. Posts set at 18 inches lean and pull panels apart. We dig to 30 inches or deeper when conditions require, and we backfill with compacted crushed rock rather than loose soil.
- Dry rot on fog-shaded fence bases: North-facing sections that never get direct sun develop rot at the picket bottoms from the constant marine moisture. Untreated pine fails first. We replace with clear-heart redwood or vinyl, depending on the exposure and the budget.
- Shallow concrete footings from original construction: Most fences built in the 1950s and 1960s used 18-inch concrete collars around untreated posts. In San Mateo’s soil, that is a temporary fence. The fix is deeper footings and a post base that separates wood from wet concrete.
Pricing for Fence Installation in San Mateo, CA

FAQs - Fence Installation in San Mateo
A geotechnical report is sometimes required for fences in San Mateo’s east-of-101 liquefaction zone, particularly for corner lots, retaining-wall-adjacent fences, or any project where the city flags the parcel. A basic residential fence on flat ground may not need one, but the depth and bracing of your footings must still be designed for the bay mud, not for generic conditions. The permitting counter will tell you, and we can pull the permit for you. Call (470) 298-9650 for an exact answer on your street.
For Bay-side San Mateo, we typically use 30-inch footings with hot-dip galvanized post bases and stainless hardware. The combination resists the saline moisture that rots standard posts and rusts standard brackets. We have used this spec in Baywood and Shoreview repeatedly, and it holds through the seasonal groundwater rise. The exact depth depends on your geotech report and soil condition at the hole.
The price difference comes from the soil, not the wood. East San Mateo sits on bay mud and fill that requires deeper footings, geotechnical review, and often a permit that Burlingame’s sandier, better-drained soil does not trigger. The coastal-spec hardware and clear-heart redwood also cost more than the inland-spec material. You are paying for a fence that does not lean or rust out within a decade.
We can replace individual rotted posts in San Mateo as a fence repair, with one caveat. If the rot has spread to the adjacent rails or the pickets are also failing at the base, the repair buys you a few years, not a decade. We will tell you which situation you have after the photo record documents the condition. Call (470) 298-9650 for a written quote on either path.
The short answer: check a USGS liquefaction susceptibility map for your San Mateo address. The practical answer: look at your fence. If the posts lean but the panels are intact, and if the ground around the posts stays wet in winter, you are likely on bay mud. We can confirm the condition during the estimate, and we will pull the geotech report if the permit requires one.
