Boral Fence Installation: The Los Angeles Owner’s Guide
Boral fence installation in Los Angeles typically runs $4,130 – $10,620 for a full replacement, with most jobs completed in two to three days once materials are on site. We stock Boral-compatible fence components and can usually match your existing profile within one visit. Most owners call us after a wind event or after noticing a section leaning, which usually comes down to failed post footings or warped rails rather than the pickets themselves.
Boral fencing is a poured polyurethane product made to look like timber but without the rot, termite, and water-damage problems you get with wood in our coastal moisture and inland heat. The catch is that when a section does fail, you can’t just patch it with off-the-shelf lumber from a big-box store and have it look right.
Which Boral Models This Applies To
Boral manufactures fence panels under a few lines you’ll see around Los Angeles, mostly the Timberlook and Dimensional profiles, along with composite post-and-rail systems. The profile naming matters because each line uses slightly different picket widths and reveal spacing. Timberlook tends toward a board-on-board or tongue-and-groove look. Dimensional runs more like a flat-top picket with a cleaner, more contemporary face.
If you have the original paperwork from the installer, look for a line item that names the series. If you don’t, measure the exposed picket width and the gap between pickets, then snap a photo of the panel edge and the post cap. That’s usually enough for us to identify the profile. One compatibility gotcha most homeowners don’t know: Boral posts are structural sleeves, and the actual load sits on a galvanized steel insert. If a post is leaning in your Los Angeles yard, the problem is rarely the Boral sleeve itself; it’s either the footing below grade or the steel insert. Reusing the sleeve with a new insert is often viable and saves real money versus a full post replacement.
On the OEM versus aftermarket question, our honest experience is this: for Boral, we stay with Boral-manufactured panels and rails when the fence is still in production. Aftermarket polyurethane pickets exist, but the color match after eighteen months in LA sun is rarely perfect, and the cell-structure density isn’t identical. For fasteners and steel inserts, we use industrial equivalents that meet or exceed the original spec.
Styles & brands we work with
Signs Your Boral Fence Installation Is Failing
- Post lean of more than 5 degrees: This almost always means the footing has shifted or the steel post insert has corroded and snapped at the base. In Los Angeles neighborhoods with expansive clay soil, like parts of the Valley, seasonal ground movement is the usual trigger.
- Panel sag between posts: Boral panels are heavy compared to vinyl. When a bottom rail wasn’t reinforced or a mid-rail has pulled loose from the post bracket, the whole span can bow downward over a few dry seasons.
- Visible cracking at picket ends or corners: Polyurethane handles sun exposure well, but a hard impact from a falling tree limb or an overzealous gardener with a string trimmer can start a crack that widens with temperature swings.
- Gaps opening between sections: Your fence should move as one line. If a section has shifted laterally, brackets have probably loosened. This is common on slopes, where LA hillside lots force longer panel runs with more stress at each junction.
- Discoloration that won’t rinse clean: Boral has decent UV inhibitors, but irrigation overspray carrying mineral-heavy LA water can leave a chalky white bloom. That’s cosmetic, but it usually signals the fence is overdue for a proper cleaning and means the surface is holding moisture longer than it should.

AfterReplacement Cost & What’s Included
Boral fence installation in Los Angeles lands between $4,130 and $10,620 for a typical residential run. The spread comes down to three things: linear footage, access, and what’s happening below grade.
- Panel and rail replacement (existing posts remain): $4,130 – $7,100 depending on profile and run length.
- Full fence installation with new posts and footings: $7,100 – $10,620 for most Los Angeles yards.
- Labor and removal of the failed section: included in the written quote, not a surprise line item.
The price we hand you is the price on the invoice. Same as every Penhallow job. That number includes removal of the old section, new materials, concrete for footings where needed, and real cleanup before we leave. You’ll get a written scope before any tools come off the truck, and every install carries the 365-Day Done Right Promise. If the work fails inside that window, we come back and fix it at no charge, in writing.
DIY or Call Us?
Boral panels are forgiving for a weekend project if the failure is a single dislodged picket and you have the matching replacement. But if the issue involves a leaning post, a snapped steel insert, or a section that’s pulled away at the rail, leave it alone. That post carries real weight, and a falling panel can hurt someone. We regularly pull out homeowner attempts in Los Angeles where a post was set in a bag of fast-set concrete in a hole too shallow, and the whole section leaned again before the season ended.
What’s worth checking yourself: whether the panel face is cracked or just the bracket has loosened, whether the post is actually out of plumb, and whether the soil at the base has eroded after rain. Beyond that, call us at (213) 277-6578 and describe what you’re seeing. We’ll tell you plainly whether it’s a repair or a replace, and the estimate is free.
FAQs
Boral fencing generally lasts 20 to 30 years in Los Angeles’s climate, with the steel post inserts being the first component to show fatigue, usually between years 12 and 20 depending on soil moisture and irrigation exposure.
Panels hold their color far better than wood, but the support structure underneath is the weak point. Call (213) 277-6578 for an inspection if your fence is past year ten and starting to lean.
Small cracks at the end of a picket can sometimes be stabilized with a matched filler and refinish, but the repaired area will never match the surrounding sun-aged color exactly.
For cracks that run through the rail or across more than a couple of pickets, panel replacement is the honest fix. We’ll tell you which path saves you money over the next five years, not just today.
Most Boral fence installation in Los Angeles finishes in two to three working days, with the first day spent pulling out the failed section and setting new footings, and the remaining time hanging panels and reinstalling hardware.
Footing concrete needs time to set properly before we hang weight on it, so we don’t rush that step. We’ll put the timeline in writing with the quote.
We stock common Boral-compatible brackets, fasteners, and steel post inserts on the truck, and we order panels and rails per job so you get the exact profile and color rather than whatever is left in a warehouse.
This also means less waste and a better match on your existing run. We can source Boral materials alongside the other trade brands we regularly work with, including KraftMaid, Cambria, and Silestone components when a project involves more than the fence line.
No. The written price we give you before work starts is the number you’ll see on the final invoice.
If we find something unexpected below grade, we stop and call you with a written change order before any additional work proceeds. That’s the Kingswell Way, and it’s been our operating standard since 2004.
