Santa Clarita Vinyl Fence: Project example: a 6-foot lattice-top vinyl fence on a shared line between two Valencia backyards, with decorative caps — what it looks like and what it costs

The scenario

The two houses are a pair of two-story tract homes in one of Valencia's planned villages, with back yards side by side and patios that look across a 5-foot wood fence into each other's dining tables. The fence runs 120 feet from the front side-yard gate posts to the rear block wall, dead straight and on flat ground, with a lawn on one side and a paver patio on the other. Both owners want more privacy but neither wants a blank 6-foot wall that cuts the light to the patios, and the village guidelines allow a 6-foot fence on an interior side line as long as it is a neutral color.

The brief that both households agree on is a 6-foot semi-privacy fence: about 5 feet of solid tongue-and-groove privacy panel topped with a foot of diagonal lattice that lets light and air through above eye level, in white to match both houses' trim, with pyramid caps on the posts. The cost is shared, so the project is priced as one fence at one rate, and the line is set exactly on the existing fence's centerline so neither yard loses ground.

The line both households agree on:

• Length: 120 feet from the front gate posts to the rear block wall
• Ground: flat, lawn on one side and pavers on the other
• Old fence: 5-foot wood, to be removed with its footings
• New fence: 6-foot white vinyl, solid below and a foot of lattice above
• Finish: pyramid caps on every post

What the job involves

1. The installer confirms the line from the existing posts and the front gate posts, and both neighbors mark their agreement on the sketch; the sprinkler heads on the lawn side and the paver edge on the patio side are flagged, and utility marking is requested.
2. The old 5-foot wood fence is taken down in panels, the posts are pulled with their footings, and the debris goes into a trailer; the paver edge is protected with plywood where posts come out next to it.
3. Post centers are marked at 8-foot spacing from the rear block wall forward, so the single short panel lands at the gate end where it is least visible from either patio.
4. Holes are augered 10 inches wide and 30 inches deep; where a hole lands beside the pavers, the edge restraint is cut back and re-set after the post is in.
5. The 5-by-5 posts are set in concrete, plumbed in both directions and strung for a dead-level top line; the next day the bottom rails with aluminum inserts, tongue-and-groove pickets, a mid rail, the lattice panels and the top rail are assembled bay by bay.
6. Pyramid caps are glued on every post, the lawn is patched at each hole, the pavers are re-set along the line, and both yards are swept of shavings and concrete spoil.

Hardware and materials

• 5-by-5 inch white vinyl posts routed for a 6-foot semi-privacy panel: privacy section below, lattice section above
• Bottom rails with aluminum inserts, tongue-and-groove pickets, a divider mid rail, 12-inch diagonal lattice panels and a top rail per 8-foot bay
• Pyramid post caps in white with vinyl-safe adhesive
• Auger with a 10-inch bit, concrete and gravel, string line, post levels, braces and a plywood sheet to protect the pavers
• Reciprocating saw and pry bars for the wood fence removal, and a trailer for the debris
• Paver edge restraint and sand for re-setting the patio edge

Add-ons often paired with this job

• Single walk gate (4 ft) — +$350–$650. A gate in a shared line is unusual, but a 4-foot gate at the front end lets both households use one side yard; it is priced as its own option.
• Tan, gray or woodgrain vinyl instead of white — +$300–$900. Tan lattice over a white body, or a full tan fence, is a common upgrade when one house has tan trim; colored material is a surcharge.
• HOA submittal package — +$100–$250. Where the village requires a courtesy notice or a design submittal for a fence visible from a greenbelt, the package is a separate line.

Why it is done this way

A lattice-top fence solves the exact problem these two yards have: it blocks the line of sight at table height while leaving the upper foot open, so the patios keep their afternoon light and the fence does not read as a wall. The lattice also breaks the wind, which matters on a 6-foot panel in a Santa Ana season, since a solid fence takes the full load and a lattice top lets part of it through.

The mid rail between the privacy section and the lattice is structural, not decorative. It carries the lattice and ties the two halves of the panel to the posts, and with the aluminum insert in the bottom rail it keeps the 8-foot bay stiff. Setting the posts on the old centerline is what keeps the project simple for two owners: neither yard changes size, the sprinklers stay where they are, and the paver edge is cut back only as far as a post needs.

Lattice top compared with the other ways to gain privacy on a side line:

• Plain 6-foot privacy blocks more view but also more light and more wind.
• Lattice top blocks the view at table height and lets light and part of the wind through.
• Picket top gives a similar effect with a more traditional look.

What would change the price

• The old wood fence has to be removed and hauled — removal is a per-foot line on top of the base rate when it is part of the job.
• One neighbor wants a taller fence than the other can accept — a different height on part of the run means custom panels or a step, which adds cost.
• The line crosses a patio or a concrete walkway — each cored post hole costs more than one in lawn.
• A privacy-top instead of lattice-top on the rear half for a hot tub — part of the run moves to the plain privacy rate.
• The front gate posts are reused and turn out to be out of plumb — resetting them in new concrete is an added item.
