Therma-Tru Fence Installation Nationwide

Therma-Tru Fence Installation: The Pomona Owner’s Guide

Therma-Tru vinyl and composite fence installation in Pomona typically runs $3,500-$9,000 for a standard residential lot, with most projects quoted and started within one to two weeks. We stock Therma-Tru-compatible posts, rails, and pickets for their Bufftech and YardScapes lines, and we carry the bracket hardware that fails first on older installs. Most Pomona homeowners find us after a wind event along the 10 or 60 corridors leaves their fence leaning, or after they notice the post footings have shifted in our clay-heavy soil.

Which Therma-Tru Models This Applies To

Therma-Tru sells fence systems under the Bufftech and YardScapes names, not the Therma-Tru door brand most people know. The Bufftech CertaGrain and Galveston series use 5-inch square posts with routed rail pockets; YardScapes uses a 4-inch post with a different bracket spacing. Check the post cap - Bufftech caps snap on with a friction fit and carry a small date stamp; YardScapes caps screw down and show the series name embossed underneath.

The critical compatibility gotcha in Pomona: Bufftech posts from 2018-2021 used a thinner-wall rail pocket that cracks under repeated thermal cycling. If your fence was installed in that window, the replacement rail needs the updated pocket wall or the failure repeats in two seasons. We source both OEM Bufftech rails and a heavier-wall aftermarket equivalent from CertainTeed that fits the same pocket and carries a comparable fade warranty. OEM matches the original color exactly; aftermarket saves roughly 15% and performs better in our inland heat. Rowan Construction Group Pomona is an independent service provider - not affiliated with Therma-Tru - and we stock both options on our trucks.

Signs Your Therma-Tru Fence Installation Is Failing

• Rails pulling out of posts. The routed pocket loosens as the vinyl expands and contracts through Pomona’s 40-degree daily temperature swings in summer. You’ll see a gap between rail end and post face before the rail drops.
• Post leaning at the base. Our local soil is heavy adobe clay that expands when wet and shrinks hard as concrete when dry. A post set without proper drainage gravel tilts within three to five years as the clay cycles.
• Picket tops discoloring or chalking. Therma-Tru’s TiO2 UV coating degrades faster above 2,000 feet elevation; Pomona sits at 850 feet, so chalking usually signals a manufacturing defect or a non-OEM replacement picket with inferior cap stock.
• Gate sagging or binding. The aluminum gate frame twists when the hinge post settles unevenly. We see this most on downhill grades in the Phillips Ranch and Lincoln Park areas where drainage runs toward the fence line.
• Bracket screws backing out. The self-tapping screws Therma-Tru specifies for rail brackets strip in recycled-content posts, especially where summer heat softens the vinyl. You’ll hear clicking in wind before you see the gap.

Replacement Cost & What’s Included

For a typical Pomona lot with 150-200 linear feet of Therma-Tru fence, replacement runs $3,500-$9,000 depending on whether we’re resetting posts, replacing rails, or doing a full teardown. Post reset with proper drainage gravel and concrete footing: $180-$280 per post. Rail replacement with OEM Bufftech: $45-$65 per linear foot. Full replacement with upgraded post depth and gravel drainage: $28-$45 per linear foot.

Every quote is a flat written price with line-item scope - post count, rail footage, hardware type, disposal - before anyone digs. Under Clause 1 of the Haven Standard, that number does not change unless you sign a change order. Our 365-Day Done Right Promise covers the installation; OEM parts carry Therma-Tru’s fade and structural warranty, and our aftermarket equivalent carries a 20-year limited warranty against cracking and color shift.

DIY or Call Us?

You can safely check whether a post is loose by rocking it at the base - any movement means the footing has failed. You can also verify your series by removing a post cap with a flathead screwdriver. What you should not do: dig out and reset a post yourself without calling 811 for utility locates, or attempt to re-pour concrete footings without knowing Pomona’s 18-inch frost depth and the 36-inch minimum depth our wind loads require.

We’ve rescued enough DIY resets in the north Pomona hills where a post went in at 24 inches and leaned within a season. Measure twice, then we can talk. Call (626) 606-1081 and we’ll give you a written price before any work starts.
