Why Barrett & Sons Construction Is Castro Valley’s Preferred Fence Installation Company
Tom Barrett started this company in 1998, and his sons run most of the crews you’ll see on a Castro Valley job. That’s not a talking point; it means the person quoting your fence is the same person accountable if something goes wrong. The name on the truck is the name on the contract, and Tom publishes his name, address, and license number for anyone to verify before signing anything. We don’t hide behind a lead-generation call center or send out subcontractors who’ve never worked a Bay Area hillside. When you call, a live person answers, 24/7.
Castro Valley homeowners have been calling us for over two decades because we understand the unincorporated Alameda County permitting process better than contractors who mostly work in Hayward or San Leandro. Your fence project might not touch a foundation, but county inspectors still apply the same scrutiny to fence footings, retaining limits, and property line setbacks. Ask anyone on your street, or look up the license number yourself. We want you to.
Our Fence Installation Services in Castro Valley
Wood Fence
Wood is what most Castro Valley homeowners want, and for good reason. Redwood and cedar both stand up to the marine fog that pools in the Castro Valley bowl longer than in flatter East Bay cities. We source pressure-treated posts rated for ground contact and recommend board-on-board cedar for privacy runs along Lake Chabot Road and other shaded hillside streets. If your lot sits on Pleasanton or Los Osos clay, we’ll pour deeper piers than the standard three feet, because shallow footings heave and twist fence lines after a wet winter. Expect to pay $3,500-$9,000 for a full wood fence replacement depending on linear feet, gate count, and whether you want stained cedar or painted redwood.
Chain Link Fence
Chain link sometimes gets dismissed as the budget option, but in Castro Valley it’s often the smart choice for hillside lots where visibility matters. Galvanized steel posts driven into concrete piers hold up to clay expansion better than wood posts, and the open weave lets fog moisture pass through instead of sitting on the material. We install both galvanized and vinyl-coated chain link for dog runs, pool enclosures, and property lines where a solid panel would block your view of the ridgeline.
Vinyl Fence
Vinyl fence in Castro Valley handles the thermal bowl’s damp winters well, with one caveat: cheap vinyl panels crack under direct summer sun and warp when the clay beneath them shifts. We spec thicker-gauge vinyl with aluminum stiffening inserts on runs longer than 20 feet, and we set posts in concrete below the expansive soil layer. If you want a white privacy fence that won’t need staining or scraping for 20 years, vinyl is your material.
Aluminum Fence
Aluminum is the right call for Castro Valley homeowners who need a fence around a pool or a decorative boundary without sacrificing the view. It won’t rust in the fog, it carries a 20-year finish warranty from the manufacturer, and we set every post in concrete with the same deep piers we’d use for wood. Expect $4,000-$10,000 for a typical aluminum fence installation in Castro Valley depending on panel style and linear footage. It’s more than chain link, but it looks like ornamental iron without the rust problem.

Trusted Brands We Service in Castro Valley
We install fences built from materials we can name, which means you can look them up before you sign. On Castro Valley wood fence jobs, we typically run Simpson Strong-Tie post bases and hardware and use pressure-treated posts from local Bay Area lumber yards that still sell the heavy Douglas fir you can’t get at a big-box store. Tom’s crew carries replacement panels and gate hardware for most major fence systems on their trucks, so if we’re repairing an existing fence, we can often match the original material on the first visit rather than making you wait on a special order. When a Castro Valley customer asks about maintenance, we’d rather hand you a brand name you can verify than a mystery product off the van.
Common Fence Installation Problems We See in Castro Valley Homes
These are the things that show up on Castro Valley fence jobs more than anywhere else in the East Bay:
- Heaved posts from clay expansion. The Pleasanton and Los Osos clay series under most Castro Valley hillside lots swells in wet winters and shrinks in dry summers. A post set in a shallow hole gets pushed up and canted over, which is why we pour 30-inch-plus concrete piers with gravel drainage instead of setting posts in dirt and hoping.
- Rotted post bases from trapped fog. The Castro Valley bowl traps marine fog and moisture longer than Livermore or Pleasanton, and it sits right at the base of the post where the concrete meets the wood. Untreated lumber rots in 5-7 years here. We use ground-contact-rated pressure-treated posts and, on wood fences, we wrap the base in a moisture barrier before setting it.
- Permit surprises on fences over 7 feet. Unincorporated Alameda County, not a Castro Valley city building department, regulates your fence. Fences over 7 feet often need a county permit, and the inspector can flag anything they don’t like about the footing design. We’ve seen stop-work orders on fences built by contractors who didn’t check the county rules first.
- Gates that sag within two years. A heavy gate hung on a post set in Castro Valley clay will pull out of plumb as soon as the ground gets wet. We frame gate posts with steel stiffeners and use adjustable hinges so the gate stays square through the seasonal shrink-and-swell cycle.
Pricing for Fence Installation in Castro Valley, CA
A standard wood privacy fence in Castro Valley runs $3,500-$9,000 depending on linear footage, grade, gate count, and whether we’re hauling off an old fence first. Aluminum fence runs $4,000-$10,000 for a typical residential lot. These ranges reflect what we’ve quoted and built in Castro Valley specifically, not a national average, and the table below breaks out the two most common materials. If your lot is steep, expect the higher end of the range; if the soil is tight and the contractor doesn’t need to fight clay, you’ll get the lower end. We put every scope, every allowance, and every price change in writing before work starts, and the price on your contract is the price you pay at the end. Call (877) 610-1318 for a line-item quote specific to your property line, not a generic range from a website.

FAQs - Fence Installation in Castro Valley
You need a permit for any fence over 7 feet in unincorporated Alameda County, and the county may require a site plan showing setbacks and property lines regardless of height if your lot sits on a slope adjacent to the Hayward Fault. A fence that replaces an existing one at the same height and location is often exempt, but hillside lots trigger extra review. Call (877) 610-1318 and we’ll tell you exactly what the Alameda County Community Development Agency will require for your specific address before you spend money on a permit you didn’t need or get hit with a correction you didn’t see coming.
Posts should extend 30-36 inches below grade, set in concrete piers with gravel drainage at the base. The expansive clay under most Castro Valley hillside lots moves enough in a wet El Niño season to push a 24-inch post right out of the ground. We set every post below the shrink-swell layer and wrap the concrete contact with a moisture barrier. On our last 1960s ranch near Lake Chabot, that meant re-setting rotted posts in 30-inch piers and the county inspector signed off without a correction.
Board-on-board western red cedar using ground-contact pressure-treated posts is what we recommend above all else in Castro Valley. The board-on-board spacing lets some of the trapped fog blow through instead of saturating a solid panel, and cedar’s natural rot resistance handles the longer moisture cycles. A solid redwood panel installed tight will more likely show warping and staining within the first two wet seasons. Call (877) 610-1318 and we’ll bring samples of both so you can see the difference before you commit.
Yes, in most cases. If the rails and pickets are still sound and the fence line hasn’t lost its plumb, we can set new pressure-treated posts in deeper piers without tearing out the entire run. That’s often the difference between a $1,200 repair and a $7,000 replacement. We’ll tell you honestly which one your fence needs. Call (877) 610-1318 and we’ll walk the line with you, for free, inside the county.
Because Castro Valley sits directly adjacent to the Hayward Fault, unincorporated Alameda County inspectors apply seismic-code caution even to non-structural work like fence permits. That means they’ll look harder at footing depth, post spacing, and retaining limits than a flatland inspector would. We’ve seen simple fence permits get held up over an undersized footing detail that a contractor working in Hayward never gave a second thought. We wrote our fence spec around what the Alameda County inspector expects before we stake the first line. That’s the difference between a fence that passes on the first inspection and one that gets red-tagged.
Call (877) 610-1318 today and Tom Barrett will come out, walk your property line with you, and give you a written scope that includes the footing depth, the material spec, and the permit fee, so you know the full price before any of our crews touch a post hole digger. We serve Castro Valley, Cherryland, Fairview, Hayward, and Ashland, and we answer our own phone, 24 hours a day.
