Boral Fence Installation: The San Francisco Owner’s Guide
Boral fence installation in San Francisco typically runs $4,130 to $10,620, and the wide spread comes down to fence height, linear footage, and whether we’re digging new posts or resetting existing ones. Most owners discover a Boral fence problem after a winter storm, when a panel cracks along the bottom rail or a post shifts in saturated soil. Boral’s composite and steel-reinforced concrete fencing holds up remarkably well in our coastal climate, but no fence product escapes the combination of fog salt air, clay soil movement, and wind gusts coming off Twin Peaks.
We stock Boral-compatible fence components and install them regularly throughout San Francisco. If you’re looking at a cracked panel, a leaning post, or a gate that no longer latches, we can usually have a written price in front of you the same week we look at it. If the fence needs a full reset or a taller privacy run, the job takes longer and the price moves accordingly.
Which Boral Models This Applies To
Boral fencing comes in a few distinct lines, and the part that failed on your fence will dictate what we order. The main series we see in San Francisco backyards are the Boral Post & Rail, the Boral Fence Board (composite and concrete), and the Boral Privacy Slat systems. Each uses a different rail channel, post sleeve, and fastener spec, and Boral does not make their parts interchangeable across lines. That matters: a post from one series will not accept the rail from another without shimming, and shimming a gate post is a shortcut we won’t take.
If you can find a label or stamp, it’s usually on the inside face of the bottom rail or on the post cap underside. No label? Measure the rail channel width and post sleeve outer dimension, and take a photo of the fence from six feet back. Our installers can identify most Boral lines from those two measurements and a photo. We use OEM Boral components when the fence is under a transferable warranty or when the color match matters, since Boral’s eucalyptus and weathered gray tones shift batch to batch. For older, out-of-warranty fences, quality aftermarket composite rails with matching dimensions can save 15 to 30 percent, and we’ll show you both options in the written estimate.

Signs Your Boral Fence Installation Is Failing
- Post leaning more than 5 degrees. In San Francisco’s clay-heavy hillsides, the culprit is usually a concrete footing that was poured too shallow (under 18 inches) or drainage that pools at the base. The post itself is often fine; the footing is the failure.
- Cracked panel along the bottom rail. This is almost always impact damage from a mower, a kid’s bike, or wind-driven debris. Boral panels are rigid by design, so they crack rather than flex when hit hard.
- Gate dragging or refusing to latch. The hinge post has shifted out of plumb, or the gate frame itself has sagged at the welded corner. We see this most on west-facing lots that catch the afternoon wind off the ocean.
- Rail pulling free from the post channel. Thermal expansion and contraction, repeated thousands of times over ten years of fog mornings and sun afternoons, eventually loosens the friction fit. A fastener add-on often fixes it without replacing the rail.
- Discoloration that does not wash off. Boral’s surface is non-porous, so staining usually means the cap coat has been compromised by abrasion or a cleaning chemical. It’s cosmetic, but it means moisture is getting closer to the core than it should.

AfterReplacement Cost & What’s Included
Installed Boral fence installation in San Francisco lands between $4,130 and $10,620, and here’s what moves the number. A single cracked panel swap with a matching color match can run toward the low end if the posts are sound. A full fence reset with new concrete footings, post sleeves, rails, and panels on a sloped Sunset District lot will push toward the high end, because every post hole in this soil fights back.
The written price includes the parts, the labor, concrete for footings, haul-away of the old fence, and our cleanup. No line items appear out of nowhere after the crew arrives; the price you approve is the price you pay. Every completed fence job is covered by our 365-Day Done Right Promise: if the gate sags or a post shifts within a year, we come back and make it right.
DIY or Call Us?
There are a few things you can check safely once a month: whether the gate clears the latch, whether any panel has a hairline crack at the rail, whether the post tops are filling with water. Those are diagnoses, not repairs. Composite and concrete fence panels are heavy, and a dropped panel can easily break a foot or a hand. The dangerous part of this job is under the surface: resetting a fence post in San Francisco means digging a hole 24 to 30 inches deep, often through clay and rock, and setting it perfectly plumb in wet concrete while keeping the rail alignment true. Get it two degrees off, and the gate will remind you every day.
If you’ve already got the replacement panel or post in the garage, we’ll install it for you and you only pay labor. If you need us to source the parts, we’ll match the correct Boral line and include that in the same written price. Call (831) 480-4497 and tell us what’s failing; we’ll take it from there.
FAQs
Boral’s composite and concrete fence panels typically last 25 to 40 years in San Francisco’s climate, with posts lasting longest when the footing is deep enough and drainage keeps water moving away from the base. Salt air and ground movement will shorten the life of the fastesteners and the gate hardware before the panels themselves fail, so budget for a hardware refresh every 10 to 15 years. Call (831) 480-4497 if you want us to inspect your fence’s hardware before it becomes a gate problem.
Small hairline cracks can sometimes be sealed with a color-matched composite repair compound, but any crack that runs edge-to-edge or is wider than 1/8 inch means the panel has lost its structural integrity and should be replaced. We’ll only suggest a repair when it buys you real years; otherwise we’ll tell you it’s time for a new panel and we’ll match the color as closely as the current Boral batch allows. Talk to Graham Stein and we’ll give you an honest read for free at (831) 480-4497.
A single panel swap takes our crew two to four hours on site, including the cleanup photo before we leave. A full fence reset with new footings usually runs two to three working days, depending on the slope, the soil, and how many concrete pours we’re doing. We’ll confirm the schedule in writing before any work starts.
We keep a small inventory of Boral panel colors, rails, and post sleeves in our San Francisco shop, but most orders are matched to the specific Boral line and color name on your existing fence and arrive within three to five business days. If you need it faster, we’ll tell you what’s in stock before you commit to anything. Call (831) 480-4497 with your fence line and we’ll check the shelf.
