AfterFast, Reliable Fence Installation Across Kensington
Fence installation in Kensington, CA typically runs $3,500-$9,000 for a full vinyl fence and $4,000-$10,000 for aluminum, depending on your hillside lot, soil conditions, and whether the county requires a geotechnical review before permitting. We’re Barrett & Sons Construction, and we’ve been working on these steep, foggy Kensington streets long enough to know that the wrong hardware fails here within a decade. If you’re considering a new fence, a repair, or a gate replacement, call Tom and the crew at (877) 610-1318 for a free estimate you can actually compare line by line.
Here’s what matters on this page: the exact failure modes we see on Kensington fence jobs, the materials we specify instead, the permit path through Contra Costa County, and honest pricing that reflects the coastal-spec work your hillside actually requires.
Why Barrett & Sons Construction Is Kensington’s Preferred Fence Installation Company
Tom Barrett started Barrett & Sons Construction in 1998, and his sons run the crews that work in Kensington today. That means the person who quotes your fence is the same family accountable when the inspector signs off. Not a franchise dispatching strangers. Not a sales rep who disappears after the contract is signed.
Kensington homeowners ask a lot of questions before they commit, and they should. They’ve usually been burned by a company that quoted one price on the phone and handed them a different bill at the door. That doesn’t happen with us. Every price change arrives as a written change order before one post hole is dug. Every permit gets pulled through the right counter, which in Kensington means Contra Costa County in Martinez, not Berkeley or El Cerrito. That one detail trips up contractors who don’t know this hill. It doesn’t trip us up.
We answer our own phone, day or night. No voicemail box, no out-of-state call center. And our 90-Day Done Right Promise is written on the contract: if something’s not done right, Tom comes back and makes it right, one call. That’s why Kensington neighbors recommend us to each other over the back fence. You can look up Tom’s name, address, and license number before you sign anything. We expect you to.
Our Fence Installation Services in Kensington
Wood Fence
Kensington’s housing stock is dominated by 1920s-1950s craftsman bungalows and Mediterranean revival homes. A wood fence here looks right on those lots, but the material choice matters more than most owners realize. The Kensington hills trap coastal fog, and that moisture works its way into posts and rails. We specify rot-resistant species, hot-dip galvanized steel posts where the hillside calls for it, and a drainage gap at the bottom rail so leaf litter doesn’t sit against the wood. It’s the difference between a fence that stands straight for fifteen years and one that sags at eight.
Fence Repair
Most repair calls we get in Kensington start the same way: the panel boards still look fine, but the posts have rotted at the soil line. That’s the signature failure mode of pressure-treated posts set directly in concrete in this fog zone. We dig out the bad post, check the concrete condition, and reset with either properly treated posts or steel, depending on the hillside and the existing fence type. If the fence was built inland-spec originally, the repair is often the time to upgrade the hardware too. That conversation happens on-site, with the price on paper before we touch anything.
Fence Gates
A sagging gate on a Kensington hillside is a safety issue as much as a nuisance. Non-galvanized hinges and aluminum gate frames corrode fast in the salt-tinged marine air, and once a gate drifts, it strains the hinges and latch. We rebuild gates with marine-grade stainless hardware and properly braced frames, and we hang them so they clear the slope they’re swinging over. A gate that opens and closes with one hand, ten years from now, is the standard we’re aiming at.
Vinyl Fence
Vinyl holds up well in Kensington’s damp climate because moisture doesn’t rot it the way it rots wood. But vinyl has its own requirements on these lots: the posts need proper depth and concrete, and the panels need enough clearance at the bottom to handle uneven grade. We also check that the profile you’re choosing is rated for the wind exposure on your side of the hill. Vinyl fence installation in Kensington runs $3,500-$9,000 for a typical residential run, and the final number depends on footage, slope, and access.
Aluminum Fence
Aluminum fence works well for Kensington lots where you want a clean sightline and low maintenance. It doesn’t rust, it handles the marine air, and it comes in grades that hold up to hillside wind. Aluminum fence installation in Kensington averages $4,000-$10,000, and the range accounts for panel height, post spacing, and whether your slope requires a stepped or racked installation. We carry premium profiles and quote the job with the grade named, so you know exactly what you’re approving.
Chain Link Fence
For a budget-friendly, functional fence on a difficult Kensington slope, chain link is often the most practical call. We use galvanized or vinyl-coated mesh and set posts deep enough to handle the soil movement these hillsides see. It’s not the prettiest fence on Arlington Avenue, but it holds a grade line better than most options when the ground drops four feet across twenty feet of run.
Iron Fence
Wrought iron and steel fences fit the older architectural character of Kensington. The catch is corrosion. The coastal fog here carries enough salt to eat unsealed iron within a few years. We specify marine-grade finishes, coat every cut and weld site, and use stainless fasteners. Done that way, an iron fence on a Kensington lot looks right and lasts. Done the cheap way, it rusts through at every joint.
Privacy Fence
Privacy fences in Kensington are common on side yards where the neighbor’s house sits right at the property line. On sloped lots, the design choices change: board spacing, bottom gap, post depth, and drainage. We walk the line with you, talk about what the grade does, and write the scope so there’s no gray area between you and the neighbor. The boundary line matters, and the permit record matters more than people expect in unincorporated county land.
Commercial Fencing
For Kensington businesses, churches, and the school district adjacent to the 94530 footprint, we handle commercial-grade fence work, including taller panels, security gates, and proper site access coordination. Different codes apply, and the county’s commercial review process is separate. We know which counter to file at and which inspector will walk the job.

Trusted Brands We Service in Kensington
We build with materials from names you can look up. On Kensington fence jobs, we regularly specify Simonton and Ply Gem profiles when the customer wants premium vinyl or aluminum, and PGT when wind ratings matter on exposed hillside lots. Those are brands with published specs and warranties, not mystery products off a van. If a customer wants a specific brand we don’t carry, we’ll say so at the estimate table and suggest an equivalent with a verifiable spec sheet. No one gets a downgrade they didn’t approve in writing.
Common Fence Installation Problems We See in Kensington Homes
- Pressure-treated posts set directly in concrete: On these foggy hillsides, that detail wicks moisture and rots the post at the soil line within six to ten years, while the panel boards above stay perfectly intact.
- Unsealed bottom rails trapping leaf litter: On sloped lots with redwood framing and heavy tree cover, the shaded bottom rail holds moisture, accelerates decay, and takes out the entire fence section from the ground up.
- Non-galvanized fence hardware: Standard steel hinges, latches, and brackets corrode quickly in the salt-tinged marine air here, leading to sagging gates and seized hardware long before the fence itself fails.
- Concrete footings too shallow for Kensington’s grade: On steep lots, a shallow post hole shifts with the first winter storm cycle. The fence leans, the gate won’t latch, and the repair is a full reset of every post along that line.
Pricing for Fence Installation in Kensington, CA
Here’s what a typical fence job in Kensington actually costs, depending on material and site condition:
| Fence Type | Typical Range in Kensington |
|---|---|
| Vinyl Fence Installation | $3,500 - $9,000 |
| Aluminum Fence Installation | $4,000 - $10,000 |
Those ranges assume a standard residential run. What moves the number on these hillside lots: slope (stepped versus racked panel installation), post depth, drainage correction, fence height, and whether the county requires a geotechnical review before the permit is issued. That last one is real in Kensington, and unlike some contractors we don’t bury it in the estimate. It’s a line item, and it’s on the table before you sign. Call (877) 610-1318 for a free, detailed quote with every line item in writing. No trip charge inside the county.

FAQs - Fence Installation in Kensington
In most cases, yes. Because Kensington is unincorporated Contra Costa County, fence permits go through the County Building Department in Martinez, not through Berkeley or El Cerrito city hall. The specific trigger is usually fence height and proximity to the property line, but on hillside lots the county may also require a geotechnical review before the permit is issued. We handle the filing, the review, and the inspection sign-off as part of our scope, and we’ll tell you up front if your lot triggers the geotech requirement. Call (877) 610-1318 and we’ll check the specifics for your address.
The Kensington hills trap coastal fog and hold measurably more moisture than the flatlands below, which accelerates wood rot in posts set directly in concrete. In El Cerrito, the same post might last twelve or fifteen years; in Kensington, we routinely pull posts that failed at the soil line in six to eight. The fix is not just a different wood species; it’s the post type, the concrete detail, and the drainage gap at the bottom rail. That coastal-spec difference is exactly what we write into every scope.
Yes. Marine-grade stainless fasteners and hot-dip galvanized steel posts cost more on the front end, sometimes several hundred dollars on a full fence run, but they double or triple the life of the hardware and post structure in Kensington’s fog and salt air. The cheap-spec fence looks fine for five or six years, then the hardware seizes, the gate sags, and the posts rot out. By year ten, the cheap version has cost more than the coastal-spec version ever would have. That’s not sales talk. That’s what we see on the repair side, pulling out the inland-spec fences that failed early.
Often, yes. On steep grades, the county may ask for a geotechnical evaluation before issuing a fence permit, and we’ve seen that request on hillside lots off Arlington Avenue. The engineering isn’t complicated for most fences, but the review adds time to the schedule, and we’d rather you know that before we start than surprise you with a delay. We build the county review into the draw schedule and the project timeline from day one.
It should name the post type, the post depth, the concrete spec, the fastener grade, the fence profile and manufacturer, the number of linear feet, the slope treatment (stepped or racked), the drainage detail, the permit and inspection line items, and any geotech review if the county requires it. A quote that just says “fence, 60 feet” isn’t a quote; it’s a guess with a number on it. We write line-item scopes with the brands named and the hardware grade specified. You’ll see every allowance on paper before you sign. For a free estimate with that level of detail, call (877) 610-1318.
