Therma-Tru Fence Installation: The Riverside Owner’s Guide
Therma-Tru fence installation in Riverside typically runs $3,500 – $9,000 including materials, labor, and haul-away of the old fence, and most projects wrap up within three to five working days once we start. You’ll usually know something’s off the same way our Riverside customers do: a gate that drags on the concrete, posts leaning after a Santa Ana wind event, or pickets that started splitting at the fastener line within the first year. Therma-Tru builds door systems and composite trim products, so when homeowners mention “Therma-Tru fence,” they’re often describing a composite or PVC privacy fence matched to their Therma-Tru entry door aesthetic, or a fence system tied into a Therma-Tru gate frame. We sort that out fast because the last thing you need is a fence that looks fine from the street and is quietly failing at the post bases.
Which Therma-Tru Models This Applies To
Here’s the thing most people don’t realize until they’re standing in the yard with a tape measure: Therma-Tru doesn’t sell a standalone fence line the way they sell door slabs. What Riverside homeowners run into is a fence or gate assembly built around Therma-Tru’s rot-resistant composite jambs and frames, usually paired with PVC or composite pickets. The compatibility question comes down to what’s actually under the paint or cap. Therma-Tru’s composite lumber profiles come in standard dimensional sizes, 5/4 x 6 and 2 x 4 being the common ones for rail and picket work, and the gate frames are pre-bored for specific hinge patterns. If you have a sticker or stamp on the back of a rail, we can match it. If you don’t, we measure the profile thickness, the shank width on the pickets, and the hinge mortise spacing. One gotcha we see in older Riverside homes, particularly in the Arlington and Victoria neighborhoods, is gate frames that were trimmed on-site to fit a non-standard opening; that changes the hinge hardware compatibility and means a straight OEM swap won’t always bolt up without re-mortising. We’ll tell you that before we order anything.

Signs Your Therma-Tru Fence Installation Is Failing
- Gate dragging or catching on the walkway. This almost always means the gate frame or hinge post has shifted, usually because the post footing wasn’t set below the frost line or the composite frame flexed under Riverside’s summer heat. The fix is re-setting the post and re-hanging the gate, not shaving the gate bottom.
- Pickets pulling loose at the screws or cracking around fasteners. Composite material expands and contracts more than wood, and if the installer used the wrong fastener or over-torqued the screws, the material splits at the hole within a season or two. Replacing pickets means matching the exact profile and color batch.
- White chalky streaks below the picket caps or rails. That’s the PVC or composite surface oxidizing under direct Riverside sun, which runs 270-plus sunshine days a year. It’s cosmetic at first, but once the cap layer wears through, water gets into the core and the rail swells.
- Wobble at the post when you press on it, with no visible crack. The post base is rotting or the concrete footing has crumbled below grade. If it’s a wood post wrapped in a Therma-Tru composite sleeve, the sleeve is hiding the real problem: a rotted pressure-treated core.
- Gate sag on the latch side even with the hinges tight. Composite gate frames don’t have the diagonal bracing wood gates rely on. If the frame was built without a proper tension rod or the hinge screws stripped out of the composite, the whole gate parallelogram-shifts and the latch stops lining up.

AfterReplacement Cost & What’s Included
For a typical Riverside backyard, a full Therma-Tru-compatible fence installation runs $3,500 – $9,000. The spread comes down to linear footage, fence height, the number of gates, and whether we’re pulling old concrete footings. A 6-foot privacy run with one gate and standard composite pickets lands near the middle of that range. A shorter decorative run with aluminum inserts sits at the lower end. A full property line with three gates, a rot-soaked post base excavation, and haul-away climbs toward the top. Every quote is a written line-item number before we pick up a tool, so you’ll see exactly what’s going into materials, what’s labor, and what’s disposal. Our work carries the 365-Day Done Right Promise in writing, and if a post settles or a gate binds within that year, we’re back out here to fix it at no charge.
DIY or Call Us?
You can safely check a few things yourself: push on each post to find the wobbly one, sight down the top rail for bowing, and look for cracked pickets around fastener heads. That tells us a lot over the phone. What we don’t recommend is digging out a failing post or trying to re-hang a gate if you’re not sure how the footings were set. Gate frames under tension can shift suddenly when you pull the hinge pins, and a 100-pound gate swinging free has pinched more than a few fingers. If you’re in Riverside and the fence is past the point of a quick check, call us at (341) 895-1170. We’ll come out, take measurements, and give you a written number, not a ballpark.
FAQs

A properly installed composite or PVC fence on good footings should last 20 to 25 years in Riverside, with the gates needing hinge and latch adjustments every few years. The material itself outlasts wood, but the post footings and hardware wear out first, which is what brings most of our Riverside callbacks around year 8 or 10.
If the damage is limited to a few pickets, a single post, or gate hardware, a targeted repair makes sense and usually runs a fraction of a full install. Once you see three or more posts failing or rot inside the composite sleeves, replacement stops being more expensive than fixing it piecemeal. We’ll tell you straight which side of that line you’re on. Call (341) 895-1170 for a free estimate and we’ll give you an honest read.
A standard Riverside backyard fence with one or two gates takes three to five working days once materials are on site. Custom gate hardware or a long property line can add a day or two. We give you a defined arrival window before we start, same as every job we do.
We keep common composite profiles, gate hinges, and post sleeves on the truck for repair calls, but full fence installs get ordered to match your existing color and profile. We source from recognized trade brands including Therma-Tru, along with other quality lines like KraftMaid, Cambria, and Silestone on the interior side of our work.
