Boral Fence Installation: The Orange County Owner’s Guide
Boral fence installation in Orange County typically runs $3,500 to $9,000 for a full replacement, depending on linear footage, post condition, and whether we’re pulling the old concrete footings or reusing them. We stock Boral-compatible post inserts and replacement pickets on our truck, so if a section has rotted at the base or snapped at a rail, we can usually match it the same week we look at it. Most owners discover the failure the way you just did: a picket’s leaning after the Santa Ana winds, a rail joint has pulled loose, or the post wobbles when you push on it – and now you’re wondering if it’s a $400 repair or a $7,000 re-fence.
Which Boral Models This Applies To
Boral’s TimberTech and TruExterior fence lines are the two we see most in Orange County backyards, from Costa Mesa to Mission Viejo. TruExterior pickets are made from a poly-ash blend, which is why they hold paint better than vinyl and resist the dry-rot that eats cedar in Irvine’s older neighborhoods near the Spectrum. Here’s the compatibility gotcha: Boral fence pickets come in 5/8-inch and 3/4-inch thicknesses, and the rail routing is cut to match – you can’t slap a 3/4-inch picket into a rail routed for 5/8 without the whole section sagging within a year. Check the back of a picket for a molded size stamp, or measure the thickness at the bottom edge before you order anything. For post replacements, we use Boral’s post sleeve over a pressure-treated 4×4 core, which handles Orange County’s clay-heavy soil better than a solid composite post set directly in concrete.
Styles & brands we work with
Signs Your Boral Fence Installation Is Failing
- Pickets pulling away from the bottom rail. This almost always means the rail was routed too shallow or the picket wasn’t seated with a polymer fastener. In coastal spots like Huntington Beach, the salt air accelerates the fastener corrosion too.
- Post lean after rain. Orange County’s clay soil expands hard in winter and contracts in summer. A post set in a shallow hole – under 24 inches – will start tilting after two or three wet seasons.
- White chalky film on pickets. That’s the poly-ash surface oxidizing, common on fences with direct afternoon sun exposure in places like Rancho Santa Margarita. It’s cosmetic at first, but left alone it roughens the surface enough that paint won’t bond later.
- Rail ends splitting at the post. This comes from thermal expansion. Boral rails move more than wood, and if the installer butted the rail tight against the post bracket with no expansion gap, the rail cracks at the screw line within a year or two.
- Gate sagging or dragging. Most Boral gates fail at the hinge screws pulling out of the composite, not at the hinge itself. The fix is usually a steel reinforcement plate behind the hinge, plus a diagonal brace if the gate’s over four feet wide.

AfterReplacement Cost & What’s Included
For a typical 50-to-60-foot backyard fence in Orange County, full Boral fence installation runs $3,500 to $9,000. That’s the written number on the front end – not an estimate range we revise at the door. What drives the spread: whether we’re pulling old concrete footings (the big one – old posts set in oversized footings add real labor), how much access the yard has for hauling materials, and whether the existing posts can be sleeved or need full replacement. A straight section swap with good posts might land around $3,500. A full teardown with new posts, new gates, and a sloped grade in somewhere like Anaheim Hills pushes toward $9,000. Every Boral fence install includes our 365-Day Done Right Promise in writing: if a post shifts, a rail splits, or a picket pulls loose inside the guarantee period, we come back and fix it at no charge. Materials from a recognized trade brand, a written line-item price before we start, and background-checked technicians in uniform on the job.
DIY or Call Us?
A single broken picket is a fair DIY fix if you have the exact thickness matched and a drill with the right polymer fasteners – Boral pickets go in differently than wood, and a framing nailer will crack the poly-ash face. What you should not do yourself is dig out and reset a leaning Boral post. Between the weight of a 6-foot composite section and the condition of old concrete footings in Orange County soil, a post swap that goes wrong ends with a fence section down and a snapped post sleeve on the ground. If the post is the problem, call us at (424) 541-1701 and we’ll look at it. We’d rather you spend an hour on the phone with us than a Saturday digging a 30-inch hole and finding out the old footing runs under your neighbor’s pavers.
FAQs
Boral TruExterior and TimberTech fencing holds up for 20 to 25 years in Orange County’s climate, which is notably longer than cedar (8 to 12 years here) and longer than vinyl in high-sun inland areas like Lake Forest, where vinyl gets brittle and yellows. The poly-ash blend doesn’t absorb the moisture that rots wood in coastal marine layers, and it handles our UV index without warping. The posts tend to be the failure point before the pickets do, which is why we set Boral posts in gravel-drained concrete with the sleeve elevated off the footing.
Yes, in many cases a Boral fence section can be repaired without re-fencing the whole run. Single pickets, rail sections, and post sleeves can all be swapped, and we do that work regularly in Orange County. The repair makes sense when the surrounding sections are still plumb and the rails are routed consistently. If three or more posts are leaning or the rail routing is inconsistent between original and replacement sections, full replacement usually costs less than chasing a partial fix that fights itself. Call (424) 541-1701 for an exact assessment – estimates are free.
A typical 50-to-60-foot Boral fence installation in Orange County takes two to three working days once materials are on site. Day one is demo and post-setting, day two is rails, pickets, and gate mounting, and we leave a day of buffer for concrete cure time and a final walkthrough with you. If we’re reusing existing posts and only swapping pickets and rails, it’s usually a one-day job. We give you a defined arrival window in writing before we start, so you’re not waiting on a vague “sometime this week.”
We stock standard Boral post sleeves, picket sizes, and polymer fasteners in our Orange County trucks, which means most repair visits don’t require a separate supply run. If your fence has a less common Boral profile or a custom color, we source it direct and have it staged before the install. We also stock parts for KraftMaid, Cambria, and Silestone product lines, since many of our fence clients are tackling bigger exterior and interior projects at the same time. Give you the number first, then pick up the tool.
If you’ve got a Boral fence section that’s sagging, splitting, or leaning in Orange County, call (424) 541-1701 and we’ll set up a time to look at it. Written price before we start, a written guarantee on the work, and a real person on the phone when you call – that’s how we operate.
