IKO Fence Installation: The Pomona Owner’s Guide
IKO fence installation in Pomona typically runs $3,500-$9,000 for a complete vinyl system, depending on linear footage, terrain grade, and whether we’re anchoring into decomposed granite or standard soil. We stock IKO-compatible posts, rails, and picket sections on our Pomona trucks, and most residential replacements are quoted with a flat written price before work starts. Most homeowners realize their IKO fence is failing when the bottom rail bows after winter rains or a gate post leans because the original installer skipped the gravel drainage layer that Pomona’s clay-heavy soil demands.
Which IKO Models This Applies To
IKO’s vinyl fence line breaks into three series: the Classic Series (4-foot and 6-foot picket heights), the Privacy Series (6-foot and 8-foot tongue-and-groove panels), and the Ranch Rail Series (2-rail and 3-rail split-rail style). The part numbers are stamped on the inside face of the bottom rail - look for a date code and “IKO-V” prefix. Posts are not interchangeable across series: Classic uses 5×5-inch posts, Privacy requires 5×5 or 6×6 depending on wind-load zone, and Ranch Rail uses 4×4. We see the most confusion with Privacy Series gates, where IKO specifies a steel-frame gate kit (model IKO-VG-68) that many Pomona homeowners don’t realize was originally installed. The steel frame rusts at the weld points after 7-10 years in our inland-heat cycle, and replacing it with a vinyl-only aftermarket gate is a compatibility mistake we correct two or three times a year. Rowan Construction Group Pomona is an independent service provider, not affiliated with IKO. We source OEM IKO components through our distributor in Ontario, plus vetted aftermarket equivalents when the OEM part is back-ordered.
Signs Your IKO Fence Installation Is Failing

- Bottom rail bows or detaches from posts. IKO’s vinyl rails expand in direct sun - we’ve measured 3/8-inch thermal movement on south-facing runs in Pomona’s summer. When installers used standard screws instead of IKO’s slotted rail brackets, the rail pops its pocket. The fix is re-securing with proper brackets, not just longer screws.
- Gate drags or won’t latch. Usually the steel gate frame has rusted at the lower hinge weld, or the post itself has shifted in poorly compacted soil. We check plumb with a 4-foot level; anything over 1/2-inch out of true means the post footing has failed.
- Post leans after rain. Pomona’s decomposed-granite subsoil doesn’t drain like coastal sand. Without a 6-inch gravel drainage base below the concrete footing, hydrostatic pressure pushes posts outward within two to three wet seasons.
- Picket tops crack or discolor. IKO’s capstock is UV-stabilized, but the lower-cost Classic Series uses less TiO2 in the cap layer. South and west exposures in Pomona show chalking and micro-cracking after eight years. We match replacement pickets by series and manufacture year.
- Concrete footing heaves above grade. This is the “lollipop” look - footing pushed up by soil expansion. In Pomona’s adobe-clay zones near Ganesha Hills, we see this where footings were poured too shallow (under 24 inches) or without expansion relief.

AfterReplacement Cost & What’s Included
| Scope | Price Range in Pomona |
|---|---|
| Single post replacement (concrete footing, IKO 5×5 post, cap) | $350-$650 |
| Section replacement (2 posts, 2 rails, 8-10 pickets, 6 ft. length) | $800-$1,400 |
| Gate rebuild (steel frame, hardware, IKO picket skin) | $1,200-$2,200 |
| Full fence replacement, 100-150 linear ft. (Vinyl Fence Installation) | $3,500-$9,000 |
The range depends on three factors: access (narrow side yards in Pomona’s older neighborhoods near downtown add labor), soil condition (decomposed granite vs. cut-and-fill lots near the 71 corridor), and whether we’re matching existing IKO color that’s been discontinued. Every quote is a flat written price with a written scope - no change proceeds without a signed change order, per Clause 1 of The Haven Standard. Our 365-Day Done Right Promise covers the installation; IKO’s limited lifetime warranty covers manufacturing defects on the materials.
DIY or Call Us?

There’s no high-tension danger with vinyl fence work, but there are two places DIY goes wrong in Pomona. First, post depth: 24 inches minimum in undisturbed soil, 30 inches if you’re in a cut-and-fill area near the hills. Second, drainage: skip the gravel base and your post will lean within 18 months. We don’t mind if you dig the holes yourself, but we do mind when we have to charge extra to pull a leaning DIY post and re-drill. What you can safely check: tap posts with a rubber mallet - a hollow sound means the concrete footing has separated from the post, which is a call-us situation. Measure gate sag with a string line; more than 1-inch drop means the steel frame is failing. For anything involving footing work or gate-frame welding, call (626) 606-1081. We’ll give you a written price before anyone picks up a tool. Measure twice, then we can talk.
FAQs
Expect 20-25 years for the Privacy Series, 15-20 for Classic, assuming proper drainage and no impact damage. The capstock UV layer degrades faster here than coastal zones - we’ve replaced Classic Series pickets after 12 years on unshaded south faces. Call (626) 606-1081 for an exact quote on replacement; estimates are free.
Individual pickets and rails can be repaired if the post footing is sound and the color match is available. If the post leans or the bottom rail pocket is torn, replacement is more cost-effective than patching. We photograph the damage and show you both options before quoting. Call (626) 606-1081 for a free estimate.
A single section (6 feet) is two to three hours. A full 120-foot residential replacement is two days: one for removal and post-setting, one for rail and picket hang. We don’t rush the concrete cure - 24 hours minimum before tensioning gates. Call (626) 606-1081 to schedule.
We stock Classic and Privacy Series posts, rails, and hardware on our Pomona trucks. Discontinued colors or Ranch Rail components typically ship from Ontario in three to five business days. We don’t start work until materials are on-site - no “we’ll come back” delays. Call (626) 606-1081 to confirm availability for your model.
