Why Barrett & Sons Construction Is Westmont’s Preferred Fence Installation Company
Barrett & Sons Construction has been owner-operated since 1998, and Tom Barrett’s sons run the crews that show up on Westmont job sites. That matters in a community like this one.

Our Fence Installation Services in Westmont
Wood Fence
Wood fences remain the most common choice on Westmont’s postwar lots, and we build them to handle the clay soil. We use pressure-treated posts set below the shrink-swell zone so the fence doesn’t lean within two seasons. Redwood and cedar are popular here for privacy runs along rear property lines, and we match the height and style to what’s already on your block.
Chain Link Fence
Chain link is still common on Westmont’s duplex lots and rental properties, and we install galvanized or vinyl-coated options that hold up under the long rainless summers. For owners with an unpermitted rear-unit conversion, a new chain link boundary fence can trigger a County compliance review, so we scope that before anyone digs.
Vinyl Fence
Vinyl fence installation in Westmont runs $3,500 to $9,000 for a typical residential run. It’s a good fit for the clay soil here because vinyl doesn’t rot or absorb water the way wood can, and it won’t warp in the August heat. We stock common panels locally, which keeps turnaround tight.
Aluminum Fence
Aluminum fencing in Westmont runs $4,000 to $10,000 and works especially well for front-yard runs and corner lots where County setback tables differ from City of LA rules. The material resists the coastal-adjacent moisture and sun without rusting or fading, and we can match existing gates on older properties.

Parts for Westmont crews are stocked through our Los Angeles office, so we don’t wait on a shipment from out of state when a gate hinge or post cap needs matching mid-job.
Common Fence Installation Problems We See in Westmont Homes
- Expansive clay soil shifting posts. Westmont sits in the South LA basin where the clay contracts through the dry months and swells in winter. Shallow concrete footings crack and posts lean. We deepen the footing below the shrink-swell zone before backfilling.
- Post-hole drilling hits old lines. On the small R-2 lots here, abandoned underground storage tanks and old septic lines from the 1950s aren’t uncommon. If our auger strikes something unexpected, we stop and call the County inspector before we backfill anything.
- Wrong jurisdiction on the permit. Crews from neighboring cities often file through LADBS not realizing Westmont is an unincorporated island governed by Los Angeles County. The filing gets bounced and the owner loses weeks. We file through LA County Public Works from day one.
- Unpermitted rear-unit conversions surface during the fence permit. Nearly every block in Westmont has one. A routine fence permit can trigger a full compliance review, and a fence that crosses into a non-compliant setback fails inspection. We flag it early and adjust the scope in writing.
Pricing for Fence Installation in Westmont, CA
A typical fence installation in Westmont runs between $3,500 and $9,000 for most residential properties. The material, the linear footage, and the condition of the soil under the existing posts drive the price. A privacy wood fence on a 55-foot rear lot line lands lower in that range. An aluminum fence wrapping a corner lot with a gate sits higher.
| Fence Type | Typical Westmont Range |
|---|---|
| Vinyl Fence Installation | $3,500 - $9,000 |
| Aluminum Fence Installation | $4,000 - $10,000 |

FAQs - Fence Installation in Westmont
In most cases, a same-footprint replacement still requires a permit through LA County Public Works, not LADBS. Westmont is an unincorporated community, so the County’s plan check queue and inspection workflow apply. We verify the exact trigger on your specific lot before quoting. Call (877) 610-1318 and we’ll tell you what the County will ask for.
Posts in Westmont need to be set below the shrink-swell zone, typically 24 to 30 inches depending on the soil at your lot, to prevent the clay from shifting them within a season or two. We check the soil before digging and spec the concrete accordingly. Call (877) 610-1318 for an exact assessment on your property.
If your fence project is near an unpermitted rear-unit conversion, the County may fold a compliance review into the fence permit, which changes setbacks, fees, and inspection timing. We’ve handled this on Westmont lots before and we flag it in the written scope before the first work happens. Call (877) 610-1318 and we’ll walk the lot with you.
Yes. Because Westmont is unincorporated Los Angeles County territory, fence height and setback standards come from County code, not LADBS. Corner lots and rear-unit conversions often face different requirements than what a City-of-LA crew would assume. We file through the County from day one. Call (877) 610-1318 with your address and we’ll tell you what applies.
Yes, and we’ve done it on Westmont’s older lots where septic lines and wells linger from the late 1940s and 1950s build-out. We locate the lines before augering, and if we hit anything unexpected, we stop and call the County inspector before backfilling. Call (877) 610-1318 for a free estimate on your specific lot.
Building on Acreage Around Westmont
Some Westmont properties sit on larger lots than the standard postwar footprint, and those jobs carry different considerations. County rather than city permitting governs the entire process. Septic tank setbacks and, where they still exist, well clearances dictate where a fence line can legally run. Long material hauls and tight equipment access on older lots change the labor and the concrete plant scheduling. Outbuildings, detached shops, and rear-unit ADUs all have their own setback tables. We scope all of that before we quote, so the price you see is the price you pay.
One Local Truth About Westmont Fence Permits
Here’s what catches out-of-area crews off guard in Westmont: fence installation permits go through LA County Public Works, not LADBS, and because this community sits in a designated unincorporated island, contractors from neighboring cities routinely file with the wrong jurisdiction and get bounced. That mistake costs owners weeks of delay before the first post hole is even dug. We live in this basin. We file through the County the first time, because we’ve been through it on enough Westmont lots to know exactly what the plan check queue asks for. It’s not a secret. It’s just local knowledge most crews never bother to learn. Ask anyone on your street, or look up the license number yourself.
On a 1952 stucco bungalow off Western Avenue, we replaced a collapsing chain link boundary fence with a 6-foot wood privacy fence while coordinating a county plan check for a detached ADU in the rear yard. During the walk, our crew flagged an unpermitted garage conversion triggered by the fence permit. We adjusted the scope of work to include a compliant side-yard setback before the County inspector’s sign-off. That’s the kind of thing you only catch when you know Westmont lots and County compliance well enough to spot it before it stops your project.
One more thing to know: when our auger hits an abandoned underground storage tank or an old septic line on these small R-2 lots, we stop and call the County inspector before we backfill anything. And we set every post below the shrink-swell zone because Westmont’s clay soil moves seasonally. If the footing isn’t deep enough, the fence leans. We’d rather do it once, in writing, and have the inspector walk it with us. Call (877) 610-1318 to schedule your free estimate. We’ll show up on time, walk the lot, and put everything in writing before a single nail moves.
