Fast, Reliable Fence Installation Across Saranap
Fence installation in Saranap runs $3,500 to $9,000 for a typical vinyl or wood privacy fence, and the price depends more on soil prep and post anchoring than on the panels themselves. That’s the part most contractors won’t tell you until the fence leans. We work in Saranap regularly, and we know that the real cost driver here is Diablo clay: get the post footings wrong and a $5,000 fence fails in eight years. Get them right and the same fence stands for thirty. Call (877) 610-1318 for a free estimate, and we’ll walk your property line before we quote anything.
Why Barrett & Sons Construction Is Saranap’s Preferred Fence Installation Company
We’re Tom Barrett and his sons. We’ve been running crews since 1998, and when you call Barrett & Sons, a live person picks up the phone – not a voicemail box and not an out-of-state call center. Saranap sits inside a ring of incorporated cities, but it’s unincorporated Contra Costa County land. That means every fence permit, every inspection sign-off, and every code enforcement action runs through the County’s Department of Conservation and Development – not Walnut Creek’s or Lafayette’s city halls. We know that boundary line, and we know the county’s fee schedule and inspection queue. Contractors who don’t know where the unincorporated boundary falls routinely submit permits to the wrong jurisdiction and leave homeowners stuck with a half-finished fence and a stop-work order. We’ve never been that contractor.
Every scope item, every allowance, and every price change arrives as a written change order before work happens. Permits get pulled and inspections get signed on every eligible job. And every completed fence is backed by our written 90-Day Done Right Promise: if it’s not done right, Tom comes back and makes it right, one call. Ask anyone on your street – or look up the license number yourself. Tom Barrett publishes his name, his address, and his license number. No mystery.
Saranap’s housing stock is dominated by 1950s through 1970s ranch-style and split-level homes. Many of those original fences are on their second or third life by now. We’ve replaced more rotted post lines on Tice Valley Boulevard and around the 94595 ZIP than we can count, and we know what those specific yards do to a fence through a wet winter and a 95°F summer.
Our Fence Installation Services in Saranap
Here’s what we actually install and repair in Saranap, and how we spec each one for this soil and this climate. These aren’t catalog descriptions – they’re what we’ve learned building fences here.
Wood Fence
Wood fences in Saranap fail from the bottom up, not the top down. The original builders set cedar and redwood posts directly into native clay, often with shallow concrete collars that hold water against the wood for months. Wet winters fully saturate the heavy Diablo clay, and dry summers pull it apart. If your gate is binding or your rails are popping nails, the posts are moving under ground. We over-excavate every post hole, set posts in gravel with drainage, and use hot-dip galvanized post anchors to break the moisture contact. Then the panels go on straight and stay straight.
Chain Link Fence
Chain link gets specified more often in Saranap than people expect, mostly for dog runs and side-yard enclosures on ranch lots. The failure mode here is the steel post base: untreated steel set in clay rusts through within a decade because winter saturation holds water against the metal for months at a time. We use galvanized posts and, where the grade is wet, stainless hardware at the tension wire. The fence itself is simple – the footing comes first.
Vinyl Fence
Vinyl fence panels without expansion gaps buckle in Saranap’s 95°F summer afternoons. The dark top rail absorbs heat and expands more than the cooler ground rail, and if the installer butted the panels tight, the whole run warps. We cut 3/16-inch relief slots at every joint and fasten with marine-grade stainless screws to prevent creep. That’s the difference between a vinyl fence that stays plumb through August and one that looks like a wave pool by Labor Day.
Aluminum Fence
Aluminum is the right call for a lot of Saranap yards because it never rusts and it holds a factory finish through wet winters. But aluminum posts still go into the same Diablo clay as everything else, so the footing detail matters just as much. We set every aluminum post in over-excavated holes with crushed rock at the base, then finish with a brushed or matte powder coat that reads as estate-quality in communities like Saranap, where unincorporated county parcels often sit adjacent to higher-density city neighborhoods.
Trusted Brands We Service in Saranap
We stock and install premium materials that you can look up before you sign anything. For fences, we carry Veka, Ameristar, and Barrette Outdoor Living, plus GAF’s deck and drainage product line where fence and landscape drainage meet. We keep fasteners, post anchors, and hardware components in local inventory that’s specific to coastal and inland East Bay conditions, so when we find a spec issue in your Saranap yard during the estimate, the fix isn’t a two-week order. It’s on the truck most days.
Common Fence Installation Problems We See in Saranap Homes
- Posts snapped at ground level from shallow concrete collars. The original builder set posts in 18 inches of concrete on top of expansive clay. Water pools at the collar, the clay swells, and the post cracks under side pressure. We saw exactly this on a ranch-style lot off Tice Valley Boulevard, where a 1970s cedar fence had posts snapped clean at grade.
- Gates that bind every summer and swing free every winter. Diablo clay’s wet-swell and dry-shrink cycle moves gate posts by half an inch or more per season. A gate hung on moving posts will never latch right. Our fix is over-excavation, gravel drainage, and post anchors that decouple the post from the moving soil.
- Rusted post bases on chain link and aluminum fences. Steel set directly in clay rusts through in under ten years. We specify hot-dip galvanized or stainless post anchors on every fence we quote in Saranap, even if the existing fence didn’t use them.
- Vinyl panels that buckle in summer heat. Vinyl expands measurably at 95°F plus, and Saranap gets plenty of days above that. Panels without relief joints warp permanently. Our installs get 3/16-inch expansion slots at every post.
Pricing for Fence Installation in Saranap, CA
Here’s what we quote most often in Saranap. These ranges include removal of the old fence where needed, over-excavated post holes, gravel drainage at every post, and galvanized hardware. Permitting runs through the County, and we handle that paperwork as part of the scope.

The clay-spec version of any fence costs about 15 to 20 percent more than a standard inland installation. That’s the over-excavation, the crushed rock, the post anchors, and the stainless hardware. We put that number in writing before we start, and we don’t come back asking for more later. The cheap spec looks fine for five years. Then the posts shift and the gate won’t close. You’ll pay for it twice. Call (877) 610-1318 for a free estimate – we’ll give you the number for your specific fence and your specific yard.

FAQs - Fence Installation in Saranap
Saranap is unincorporated Contra Costa County land, so every fence permit runs through the County’s Department of Conservation and Development. Walnut Creek operates under its own city building department with different thresholds. That’s why one side of the street may need a county permit while the other doesn’t. In Saranap, we pull the county permit, schedule the county inspection, and get the sign-off before we call the job done. Call (877) 610-1318 and we’ll check your exact parcel before you spend a dollar.
Plan on 15 to 20 percent above a standard bid. That covers over-excavating each post hole to 30 inches, backfilling with crushed rock and gravel for drainage, and setting posts on hot-dip galvanized anchors instead of burying wood in concrete. The standard installation skips those steps. The clay-spec fence will still be standing when the cheaper one is leaning against your neighbor’s hedge.

Yes, we do this regularly on 1950s through 1970s ranch homes in the 94595 ZIP. On a Tice Valley Boulevard lot, we re-hung the owner’s existing redwood boards after re-milling the cupped bottoms and replacing every post. You save the cost of new lumber, and the fence keeps its original character. The catch is that old boards sometimes crack during removal, so we quote a board-replacement allowance in writing before we start. No surprises at the end.
We use stainless steel hinges, latches, and strike plates on every gate in Saranap. Standard zinc-plated hardware rusts through within a few wet seasons. Saranap’s inland valley position shields it from coastal fog but still delivers fully saturated soils all winter, and that moisture wicks into whatever hardware touches the ground or sits near it. Stainless costs more up front. Replacing rusted hardware every five years costs more by year ten.
The gate posts moved. Diablo clay shrinks as it dries through Saranap’s hot summers, which pulls post footings slightly toward the path of least resistance. Even an inch of movement throws a latch out of alignment. The fix is resetting the posts with over-excavation and gravel drainage, not just shimming the latch. If your gate already sticks or swings open on its own, call (877) 610-1318 and we’ll assess it for free.
