Owens Corning Fence Installation: The Woodland Hills Owner’s Guide
Owens Corning fence installation in Woodland Hills typically runs $3,500 to $9,000 for a standard residential lot, including materials, removal of the old fence, and labor. Most jobs wrap up in two to four days once we’re on site. Here’s the thing: Owens Corning doesn’t manufacture fencing. They’re known for roofing, insulation, and composites. So if you landed here looking for an “Owens Corning fence,” what you likely have is a fence built with Owens Corning composite decking boards repurposed as fence pickets, or you’re thinking of a composite fence from a brand like Trex or TimberTech and Owens Corning came up in your search because of their composite material reputation.
Either way, we know exactly what you’re dealing with, and we’ll tell you straight: composite fence materials fail differently than wood or vinyl. The good news is that a composite fence done right will outlast pressure-treated lumber by a decade or more in Woodland Hills heat. The bad news is that when a composite fence does fail, it’s almost never just one board. We’ll get into why below.
If your fence is sagging, boards are pulling loose, or the posts are leaning toward the neighbor’s yard on a hillside off Mulholland, call us at (341) 217-2776. We’ll get you a written price before any work starts.
Which Owens Corning Models This Applies To
Here’s the reality of the Owens Corning name in fencing: there is no Owens Corning fence product line. What exists is a category of composite boards, some of which carry the Owens Corning name from older decking lines (they exited the composite decking market years ago), and a much larger category of composite fence boards from other manufacturers that homeowners in Woodland Hills often match to Owens Corning because they’re already familiar with the brand from their roof.
If you have boards stamped or stickered as Owens Corning, what you likely have is a fence built from their older composite decking stock, repurposed as fence pickets. Those boards are typically 5/4 x 6 nominal (about 1 inch thick by 5.5 inches wide) and come in 12-, 16-, and 20-foot lengths. If the boards are grooved on both edges, the original installer used hidden fasteners; if they’re square-edged, the boards were face-screwed.
For replacement, we match the profile, color, and fastener pattern. In most cases, a quality aftermarket composite board from a current manufacturer will outperform the original Owens Corning decking stock, because today’s composite formulas have better UV stabilizers. California sun is brutal on composite color. If the original boards haven’t faded to chalk by year eight, they’re doing better than most.
One more thing: Sawyer Remodel Woodland Hills is an independent contractor. We’re not affiliated with Owens Corning, and we don’t pretend to be. We just know their materials and the composite category inside out.
Styles & brands we work with
Signs Your Owens Corning Fence Installation Is Failing
- Sagging or drooping between posts. Composite boards are heavier than cedar and they’ll flex under their own weight if the rails are spaced too far apart or the original installer used wood rails that have since rotted. We see this constantly in Woodland Hills, especially on fences that run north-south and catch full afternoon sun.
- Boards pulling away from the rails. Face screws in composite work themselves loose over time because the material expands and contracts more than wood. If you can see screw heads backing out or boards rattling in the wind off Topanga, the fasteners are done.
- Chalky or faded boards. UV breakdown shows up as a white, powdery surface that rubs off on your hand. It’s cosmetic at first, but it means the board’s protective cap layer is gone, and moisture intrusion is next. In Woodland Hills, expect this around year seven to ten on older composite formulas.
- Leaning posts, especially on slopes. Composite fence panels are heavy, and posts set in shallow concrete or without proper drainage will shift. Hillside properties in the Santa Monica Mountains foothills get real soil movement in winter rains. A leaning post is the canary in the coal mine.
- Mold streaks or dark staining at board ends. Composite doesn’t rot, but it does trap moisture where boards butt against each other or against concrete. If you see black streaking along the bottom rail or at post bases, water is sitting where it shouldn’t.

AfterReplacement Cost & What’s Included
For Woodland Hills, a full Owens Corning-style composite fence replacement runs $3,500 to $9,000. That range covers removal and disposal of the old fence, new posts set in concrete, new rails, new composite boards, all fasteners, and a final walkthrough. The spread comes down to three things: linear footage (most Woodland Hills backyards run 80 to 160 feet), terrain (hillside fencing takes longer and requires deeper post holes), and whether you’re keeping the existing posts or replacing them.
Here’s the breakdown:
- Partial repair (a few boards, one section): $350 – $900
- Full fence replacement, flat lot, 100 feet: $3,500 – $5,000
- Full fence replacement, hillside, 150+ feet: $6,000 – $9,000
Every quote includes the written price before we start, and the number on the invoice is the number you approved. No change orders unless you ask for something different mid-project, and even then you get the new price in writing before we pick up a tool. The work carries our 365-Day Done Right Promise: if it’s not done right, we make it right, in writing, for a full year.
DIY or Call Us?
You can inspect a composite fence safely. Look for screw heads backing out, boards that wiggle when you push on them, and posts that don’t stand plumb. Those checks take ten minutes and they’ll tell you whether you have a fastener problem or a structure problem.
What you shouldn’t do is pull posts and reset them on a hillside without the right equipment. A 10-foot composite section is heavy enough to hurt someone if it comes down wrong, and a post hole dug into loose hillside soil without proper drainage will fail again inside two years. We’ve fixed enough DIY post replacements in the neighborhoods above Topanga Canyon Boulevard to know exactly how that story ends.
If you want to know whether you’re looking at a $400 repair or a $7,000 replacement, call (341) 217-2776. We’ll send someone out, look at the fence, and give you a written price. The estimate is free.
FAQs
A well-installed composite fence in Woodland Hills lasts 15 to 25 years, with color fading starting around year seven to ten depending on sun exposure. Boards with a full cap layer (a thicker UV-resistant shell) hold their color longer than older formulas. Posts are almost always the weak point, not the boards.
Yes, if the posts are solid. We can replace individual boards, rails, or a full section without touching the rest of the fence. But if the posts are leaning or rotted, a partial repair is just delaying the inevitable. We’ll tell you which situation you’re in before you spend anything. Call (341) 217-2776 for an exact quote.
Most Woodland Hills fence replacements take two to four days on site. A typical 100-foot flat-lot fence is a two-day job. Hillside work with difficult access can run three to four days. You’ll get a schedule in writing before we start, and we show up on time.
We stock current composite boards that match the profile and color of most Owens Corning-era decking boards used in fencing, and we can source exact-match boards for older colors within a few days. We also work with materials from KraftMaid, Cambria, and Silestone on the remodeling side, so we know our way around supplier networks that most fence companies don’t touch.
