Fast, Reliable Fence Installation Across Altadena
Fence installation in Altadena today carries a set of rules that didn’t exist two years ago. After the Eaton Fire, LA County tightened what can be built, how it must be anchored, and what happens before the first post hole goes in. If you’re rebuilding a fence on a burned lot off Lake Avenue or replacing an old redwood line on a canyon-adjacent parcel near Angeles Crest, you need a contractor who knows how unincorporated LA County actually processes permits, what the Very High Fire Hazard Severity Zone codes require, and why soil testing comes before digging. That’s exactly what our Fence Installation team handles every week across the 91001 and 91003 zip codes. Call (877) 610-1318 and we’ll walk your lot with you, scope the job on paper, and give you a written price before anything moves.
Why Barrett & Sons Construction Is Altadena’s Preferred Fence Installation Company
Barrett & Sons Construction was founded in 1998, and Tom Barrett’s name, address, and license number are published for anyone to look up before signing. That matters in Altadena, where homeowners have already been through enough surprises. We answer the phone with a live person, day or night, and the crew that shows up has our name on the truck.
Altadena isn’t a city, and that changes everything about how a fence job gets permitted and inspected. We’ve pulled enough LA County Department of Public Works permits on fence lines here to know which reviewer wants what, which soils need geotechnical sign-off before post piers are dug, and which lots in the burn zone are still flagged for contaminated soil. That local familiarity saves time and keeps your draw schedule moving.
Every job we do in Altadena, from a simple chain link run across a flat lot to a 1,200-linear-foot aluminum perimeter on a hillside, comes with the 90-Day Done Right Promise written into the contract. If something isn’t right, Tom comes back. One call. That’s not a marketing line; it’s the same promise we’ve kept for over 29 years.
Our Fence Installation Services in Altadena
Wood Fence
Wood fences remain the most requested option in Altadena, but the rules around them changed after the Eaton Fire. In the burn zone and much of the hillside areas, LA County now mandates noncombustible or ignition-resistant materials for replacement fencing. That doesn’t always mean no wood. It can mean a wood privacy fence with metal posts, concrete post piers, or an ignition-resistant treatment approved by the county. We scope it to match what the county will actually sign off on, so you don’t pay for lumber, have it red-tagged, and start over.

Aluminum Fence
Aluminum fencing fits Altadena’s new reality better than almost anything else. It won’t burn, it meets the WUI material requirements, and it holds up against the Santa Ana winds that sweep down from the San Gabriels every fall. We install aluminum fence panels from manufacturers like Simonton and Ply Gem, set on reinforced concrete piers that won’t shift when the alluvial soils beneath them go through wet and dry cycles.

Fence Gates
Driveway gates in Altadena demand more than a hinge and a latch. Every automatic gate needs a separate power allowance, and the county wants the footprint set up for emergency access. Fire access is not a suggestion up here. We install custom steel and aluminum gates with the clearances and setbacks the county inspector wants to see, and we wire them for whatever access system you plan to use.

Vinyl Fence
Vinyl fencing works well on the flatter, lower-lying lots in the northern 91001 areas where the soil is more predictable. It’s low-maintenance, it’s never going to rot or warp, and we run it on the same deep-set concrete piers as everything else. A typical vinyl fence installation in Altadena runs $3,500 to $9,000, and if you’re in a wind-exposed pocket off Lake or Fair Oaks, we’ll upsize the post schedule to keep it dead straight through Santa Ana season.

No waiting while a part rides a freight truck from three states away.
Common Fence Installation Problems We See in Altadena Homes
- Wood posts without WUI-compliant upgrades: Contractors who don’t work the burn zone regularly will quote a standard wood post. The county inspector red-tags the rough-in, and the fence doesn’t pass before draw schedule completion. We plan posts to meet the VHFHSZ requirements from the first quote.
- Alluvial-fan soils shifting posts: Altadena sits on soil that moved significantly during fire suppression and subsequent rains. Posts set too shallow or without proper piers lean within one season, bowing the line and throwing gate hinges out of alignment. We set deeper and reinforce based on the specific soil on your lot.
- Skipping soil contamination testing: In the burn zone, ash leachate is still present in the ground. Drilling post holes without the required testing can trigger a stop-work order and a decontamination bill that no one budgeted for. We verify what’s required before the auger ever touches dirt.
- Gates that ignore fire-access code: Automatic driveway gates in Altadena need specific clearances and emergency access protocols. A gate that swings the wrong way or blocks a fire truck’s access won’t pass the county inspection, and you’ll be re-flooring the whole installation. We build gates to the county’s fire access standard from day one.
Pricing for Fence Installation in Altadena, CA
Most residential fence installations in Altadena fall between $3,500 and $9,000, depending on linear footage, material, terrain, and what the soil on your lot requires. Aluminum and steel systems run higher because the material costs more and the code requires specific post-depth and pier details in much of the burn zone. Here’s how the main options break down:
| Fence Type | Typical Altadena Range |
|---|---|
| Aluminum Fence Installation | $4,000 - $10,000 |
| Vinyl Fence Installation | $3,500 - $9,000 |
| Wood Fence Installation (WUI-compliant) | $3,500 - $9,000 |
| Custom Steel or Aluminum Driveway Gate | Quoted per job, typically starting around $2,500 |
Every scope, every allowance, every price change arrives as a written change order before work happens. The allowance that isn’t on paper is a surprise waiting for a date. Call (877) 610-1318 and Tom or one of his sons will walk your lot, write the scope, and hand you a price you can take to the bank. Estimates are free, and there’s no trip charge inside the county.

FAQs - Fence Installation in Altadena
Yes, in most cases you need a permit through LA County Department of Public Works, not a city building department. Altadena is unincorporated, so all the permitting flows through the county, and much of the burn zone sits in a Very High Fire Hazard Severity Zone requiring noncombustible or ignition-resistant fencing materials. We handle the permit application, drawings, and scheduling with the county as part of the job. Call (877) 610-1318 to get the exact scope for your lot.
Only if your lot falls outside the VHFHSZ boundary and the county approves the plan. Many lots in the northern 91001 zip code and along the wildland edge cannot use standard redwood posts or untreated wood without a WUI-compliant upgrade such as metal posts, masonry piers, or ignition-resistant materials. We’ll tell you what’s approved for your specific address before you spend a dollar on lumber, and we’ll put that determination in writing. Call (877) 610-1318 for a free site check.
Soil testing is required on many Altadena burn-zone lots because ash and burned material leach heavy metals and volatile organic compounds into the ground. Drilling post holes without that testing can trigger a stop-work order and a decontamination bill that wasn’t in the original scope. We confirm what’s required for your parcel and include the testing in the written quote so there are no surprises mid-job. Call (877) 610-1318 to get an exact scope.
Altadena’s alluvial-fan soils shift through wet and dry cycles, especially after the fire and the heavy water saturation the hillsides took. That means posts need deeper concrete piers than a typical flat-lot fence job, often 2 feet or more with ember-resistant footing details. We set posts to handle the specific soil conditions on your lot, not a generic one-size-fits-all depth. Call (877) 610-1318 and we’ll explain what your soil requires.
Yes. Automatic driveway gates in Altadena require a separate power allowance from LA County, and the gate footprint has to be engineered for emergency access. That’s not a suggestion when fire trucks need to reach your property. We build gates with the proper clearances, setbacks, and power provisions so the county inspector signs off the first time. Call (877) 610-1318 to scope your gate installation and get a written quote.
