Boral Fence Installation: The Mountain View Owner’s Guide
We stock and install Boral-compatible fence systems in Mountain View, with typical installed pricing running $3,500-$9,000 depending on linear footage, substrate condition, and whether we’re matching an existing Boral profile or starting fresh. Most Boral fence inquiries we get in Mountain View come from owners who’ve discovered cracking, leaning, or moisture damage after the winter rains - the coastal fog cycle here traps moisture at the base, and Boral’s concrete-composite boards don’t rot like wood, but the posts and hardware still can.
Which Boral Models This Applies To
Boral fencing in Mountain View typically means the Boral Tru-Exterior or Boral Versetta Stone lines, though we’ve also matched Boral board-and-batten profiles on custom installs near Castro Street. The Tru-Exterior line uses a fly-ash and polymer composite that’s dimensionally stable - it won’t check or split like fiber-cement - but the mounting clips, post sleeves, and cap rails are model-specific. Check the back face of any existing board for a stamped date code and profile number; Tru-Exterior boards marked “TX-6” or “TX-8” use a different clip spacing than the older “Boral Classic” series we see in some 2015-2018 Mountain View builds.
We source OEM Boral hardware through their West Coast distributor, but for post sleeves and cap rails we often spec Fortress Building Products equivalents - same gauge aluminum, same powder-coat spec, shorter lead time. The boards themselves we keep Boral; third-party composite doesn’t carry the same density rating and won’t take the same fasteners without mushrooming. If your fence is Versetta Stone, the corner units and ledgers are proprietary - no aftermarket equivalent exists that we’ve found, and we’ve looked.
Signs Your Boral Fence Installation Is Failing

- Boards pulling away from rails at the clip points. Boral’s hidden-clip system relies on stainless screws into aluminum rails; in Mountain View’s salt-air exposure near 101, galvanic corrosion between dissimilar metals weakens the grip. We find this most often on fences within a half-mile of the freeway corridor.
- Post leaning or wobble, especially at gates. The post itself is usually sound - Boral uses steel or aluminum posts - but the concrete footing has cracked from root intrusion or the seasonal clay expansion common in Old Mountain View lots. The post doesn’t fail; what holds it fails.
- Cap rail lifting or water pooling at board tops. Boral cap rails are meant to shed water, but if the end-caps weren’t sealed with polyurethane during install, fog moisture wicks into the hollow rail and adds weight. We’ve replaced cap rails on three-year-old fences where this detail was skipped.
- Staining or efflorescence at the base. Boral boards are impervious to rot, but they’re not impervious to wicking. In Mountain View’s heavy clay soils, water climbs the board face and leaves mineral deposits. The board is fine; the aesthetic isn’t, and the wicking can corrode the bottom rail if it’s aluminum.
- Gate sag or latch misalignment. Boral gates use heavy-duty hinges, but the gate frame is aluminum tube - strong but light. Without proper diagonal bracing or a steel frame insert, the gate twists under its own weight over time, especially on south-facing exposures where thermal expansion is greatest.

AfterReplacement Cost & What’s Included
| Scope | Price Range |
|---|---|
| Boral fence repair (localized: posts, rails, clips) | $1,200-$3,500 |
| Partial Boral fence replacement (match existing profile) | $3,500-$6,500 |
| Full Boral fence installation, new layout | $5,500-$9,000 |
| Boral gate rebuild with steel frame insert | $800-$2,200 |
What drives the range: linear footage is obvious, but the hidden variable is substrate. Mountain View lots near the Stevens Creek corridor often need post-depth adjustment for drainage; downtown blocks near Castro can have utility conflicts that require hand-digging. Our quote includes the Boral materials, aluminum or steel posts, concrete footings, and all hardware. Under Clause 1 of the Haven Standard, you get the written price before anyone digs - no “we’ll see once we’re in” surprises. The 365-Day Done Right Promise covers workmanship; Boral’s material warranty runs 25 years on Tru-Exterior boards, which we register in your name.
DIY or Call Us?

There’s no high-tension danger in fence work - no springs, no electrical, no gas - but there’s a lot of ways to build a fence that looks straight and isn’t. A post can be plumb in two directions and still be in the wrong place for gate swing clearance. Boral’s clip system requires a specific reveal gap (3/16 inch) for thermal expansion; nail it tight and boards buckle by summer.
What you can safely check: tap posts with a wrench - a dull thud means solid concrete, a ring means hollow or loose. Check the cap rail end-caps for intact sealant. Measure gate diagonals - if they’re more than a half-inch different, the frame is twisting.
What goes wrong fast: digging without 811 clearance (Mountain View has dense utility runs), mixing concrete in the hole instead of a proper pour, or assuming Boral boards cut like wood - they don’t, they chip, and a fine-tooth miter blade is mandatory. We’ve redone two DIY Boral installs in the last year where the owner saved $800 and spent $3,200 fixing it. Measure twice, write it down, then build it that way.

FAQs
Boral Tru-Exterior boards carry a 25-year warranty and typically last 20-30 years in Mountain View’s fog-and-sun cycle. The weak points are the aluminum rails (15-20 years in salt-air exposure) and the post footings (varies with drainage). Call (669) 215-4852 for an exact quote on your specific install - estimates are free.
Localized failure - one leaning post, a cracked cap rail, clip corrosion on a single run - we repair. If the rail system is failing across multiple sections or the posts are out of plumb due to footing degradation, replacement is more cost-effective than chasing symptoms. We document both options with photos so you can decide. Call (669) 215-4852 for a free estimate.
A standard 40-linear-foot Boral fence in Mountain View takes two to three days: one for layout and post-setting, one for rail and board hang, half-day for gates and hardware. Permits add three to five business days if the fence is over six feet or on a corner lot. We pull permits as standard; it’s included in the written scope. Call (669) 215-4852 to schedule.
We stock Boral-compatible aluminum rails, clips, and post sleeves in our Mountain View warehouse. Boral Tru-Exterior boards ship from their West Coast distributor in three to five business days; Versetta Stone corner units and ledgers can take seven to ten. For repairs, we can often stabilize same-day with temporary posts while boards arrive. Call (669) 215-4852 to confirm stock for your profile.
