Unilock Fence Installation: The Dallas Owner’s Guide
Unilock fence installation in Dallas typically runs $3,500 to $9,000 for a complete perimeter project, including the wall block, base prep, drainage, and cap finishing. We stock Unilock-compatible components and can usually schedule your fence installation within two weeks of the written estimate. Most owners call us after a section has shifted out of plumb or a retaining wall doubled as a fence and started leaning – that’s the number one failure pattern we see across Dallas yards, where clay soil expansion and contraction works against rigid vertical structures every single season.
Which Unilock Models This Applies To
Unilock fence installation in Dallas covers two distinct product lines: the Estate Wall system and the RomanStack retaining wall units used as fence columns or low perimeter walls. The Estate Wall uses a tongue-and-groove lip on the back of each block, which locks courses together without visible mortar lines. RomanStack, by contrast, relies on a glass-fiber reinforced pin system inserted into pre-cast holes – and that pin compatibility is where we see DIY jobs go sideways. Homeowners buy RomanStack blocks from one supplier and pins from another, then discover the pins don’t seat. We match the exact Unilock series number stamped inside the block core before ordering anything.
For fence columns built from Unilock wall block, the cap unit matters. Estate Wall caps are 3 inches deep to sit proud of the 6-inch block; RomanStack caps taper slightly for water runoff. We recommend OEM Unilock blocks and caps for any fence application in Dallas specifically because the freeze-thaw cycle here, while milder than the Midwest, still affects cheaper aftermarket block made with lower cement content. Unilock block runs 4,000 psi compressive strength minimum. Budget look-alike block often tests below 3,000 psi. For a fence that’s carrying gate hinges or wind load, that gap shows up as crack lines within five to seven years.

Signs Your Unilock Fence Installation Is Failing
- Leaning columns at gate posts. This is the classic Dallas failure: the gate’s weight and swing momentum exceed what the column base can hold, usually because the original installer poured a shallow footing. The fix requires dismantling the column, pouring a proper 36-inch-deep concrete pier with rebar, and rebuilding the Unilock courses around a steel core.
- Cap stones shifting or falling off. Caps rely on a polyurethane adhesive that degrades under Texas UV exposure in about four to six years. You’ll see a cap seated crooked or hear it scrape when you set a hand on it. This is a fast, low-cost repair if caught before water gets behind the block face.
- Horizontal cracks along a mortar line (if mortared). Soil movement from Dallas’ expansive clay expands and contracts the ground under the wall. A rigid mortared joint can’t flex, so it cracks. Unilock’s dry-stack systems with pins handle this better, which is one reason we steer Dallas fence projects toward those lines.
- Base course sinking or settling. The first course below grade has shifted downward, usually because the original gravel base was too thin or not compacted in lifts. You’ll see a visible dip in the fence line or a gap opening at the bottom of a column.
- White mineral staining (efflorescence) spreading. Efflorescence itself is cosmetic, but persistent and spreading staining tells us water is moving through the block. On a Dallas fence, that means drainage behind the wall wasn’t installed correctly or the cap overhang isn’t shedding water. Left alone in repeated freeze-thaw, the trapped moisture eventually spalls the block face.

AfterReplacement Cost & What’s Included
For a full Unilock fence installation in Dallas, our typical range is $3,500 to $9,000 depending on linear footage, whether it’s a single fence line or integrated columns with gates, and site access. Here’s the breakdown of what drives that number:
- Block and cap material: $12 to $22 per square foot of face area, depending on the Unilock series and color.
- Base prep and drainage: $6 to $10 per linear foot for compacted gravel base, filter fabric, and perforated drain tile where the fence retains grade.
- Structural cores for gate columns: $350 to $700 per column when rebar and poured concrete fill are required.
- Labor: $45 to $75 per hour per crew member, with a typical 3-person crew moving 50 to 80 square feet of wall face per day.
Every line-item is on your written estimate before work starts. No numbers move at the door. And like every Bradford Remodeling Co Dallas project, your Unilock fence installation carries the 365-Day Done Right Promise: if the block shifts, a column leans, or a cap fails within a year of completion, we return and correct it at no charge. That’s in writing, signed, in your hand at close-out.
DIY or Call Us?
You can safely inspect a failing Unilock fence yourself: check for leaning columns, tap cap stones to see if they’re loose, and run a 4-foot level along the top course. What you should not do is dismantle a leaning Unilock column that’s holding a gate. That gate is under tension, and once the block courses are compromised, releasing the hinge side can drop several hundred pounds in a direction you didn’t plan. If a column is leaning or a base course has sunk, call a crew. Bradford Remodeling Co Dallas will send background-checked, uniformed technicians who know the difference between a cosmetic cap repair and a structural rebuild. Call (903) 326-8963 and we’ll come out, assess what you’ve got, and give you a straight number.
FAQs
Properly installed Unilock fence systems in Dallas last 25 to 40 years for the block itself, with the base prep and drainage determining whether you get the low or high end of that range. The cap adhesive joints need re-bedding every five to seven years from UV exposure. If your fence is failing in under ten years, it’s almost always a footing or drainage problem, not a block problem. Call (903) 326-8963 and we’ll confirm what’s actually going on before you spend a dollar.
Yes, single-column rebuilds, cap re-bedding, and base re-leveling are all repairs we do regularly in Dallas without touching the rest of the fence line. We match Unilock block series and color, and blend where needed. If three or more columns have failed or the base course has shifted across more than 20 percent of the run, full replacement is usually the cheaper long-term answer. We’ll tell you which one applies to your fence, in writing, before any work starts.
A typical 40 to 60 linear foot Unilock fence installation in Dallas takes four to seven working days from base prep through final cap setting. Gate columns with poured concrete cores add a day each. Weather delays happen, but we schedule a written scope with a start date and a completion window before the first block is laid. No open-ended timelines, no disappearing crew.
We stock Unilock Estate Wall and RomanStack cap units, pins, adhesive, and drainage materials on our Dallas trucks for common repair calls. Full fence runs of block and color-matched caps are ordered per project from Unilock’s regional distribution, which means a three to five day lead time for materials on new installations. We also work with KraftMaid, Cambria, and Silestone products on kitchen and bath work, so material logistics are a daily discipline for us, not a surprise.
