Unilock Driveway & Pavers Nationwide

Unilock Driveway & Pavers: The Pasadena Owner’s Guide

Unilock paver driveway repair and replacement in Pasadena typically runs $7,000-$18,000 for a full install, with spot repairs starting around $1,200-$3,500 depending on base failure extent and paver series availability. We stock Unilock-compatible pavers and matching edge restraints for most Beacon Hill, Richcliff, and Thornbury series jobs, and we can usually source same-day from Unilock’s Southern California distribution for less common colors. Most Pasadena owners realize something’s wrong when they notice the pavers shifting under tire load or water pooling where it used to drain, often after one of our rare but heavy winter storms saturates the bedding sand.

Which Unilock Models This Applies To

Unilock’s driveway line breaks into three tiers, and the part you need depends on which system was originally installed. The Classic series - Hollandstone, Brussels Block, Courtstone - uses a standard 60mm paver with conventional edge restraint; the Premium series - Beacon Hill Flagstone, Richcliff, Thornbury - runs 80mm thick with Unilock’s proprietary ColorFusion or EnduraColor facings that require matching for repairs; and the permeable line - Eco-Priora, Tribeca - needs specific bedding and joint aggregates that don’t interchange with conventional installs.

To identify your series, flip a loose paver or check the edge of a cut. Unilock stamps the mold number on the side wall of every unit produced after 2012. The Premium facings are cast, not pressed, so the surface layer is roughly 3/16″ thick and will show a clean break if chipped rather than the aggregate-through pattern of a through-body paver. We carry stock for the Classic and Premium lines on our Pasadena truck; Eco-Priora and other permeable aggregates we pull from the Rancho Cucamonga yard, usually next morning.

OEM Unilock pavers are the safe match for ColorFusion and EnduraColor repairs - aftermarket equivalents exist for the Classic pressed lines, but the color drift over five Pasadena summers of UV exposure means a side-by-side patch usually reads as two different jobs. We quote both options when the difference matters to the budget.

Signs Your Unilock Driveway & Pavers Is Failing

• Pavers rocking under vehicle weight. The bedding sand has washed out or compacted unevenly, often from a failed edge restraint that let the perimeter spread. In Pasadena’s freeze-free climate this is almost always drainage-related, not frost heave.
• Standing water 30 minutes after rain stops. The joint sand is gone or the base has settled. On sloped driveways this usually traces to a low spot where the screeded base wasn’t true; on flat installs it’s often a clogged channel drain.
• Weeds growing through joints wider than 1/4 inch. Polymeric sand has degraded or was never installed. The gap itself is the symptom, but the underlying cause is usually base movement or an initial install that skipped the plate compactor step.
• Chipped or spalled surface on ColorFusion pavers. The wear layer has taken impact damage or delaminated from freeze-thaw cycling, rare here but possible on north-facing slopes in San Rafael or Linda Vista where frost lingers. Repair requires full paver replacement; the facing cannot be patched.
• Sunken area near the garage threshold or curb cut. The aggregate base wasn’t compacted in lifts during original construction, or utility trench backfill has settled. This is structural, not a paver problem, and lifting the surface without addressing the base guarantees recurrence within two years.

Replacement Cost & What’s Included

Full Unilock paver driveway replacement in Pasadena runs $7,000-$18,000 for a typical two-car apron and approach, with the spread driven by paver series selection, base depth requirements for clay soil areas near the Arroyo Seco, and whether we need to haul off an existing concrete slab or work over a sound aggregate base. Spot repairs for isolated base failure start at $1,200-$3,500; edge restraint replacement alone, when the base is still sound, runs $800-$2,200 depending on linear footage.

Every quote separates materials from labor, names the Unilock series and color code, and specifies base depth and compaction method. Under Clause 1 of the Haven Standard, that written price is fixed; no change order moves without your signature. Our 365-Day Done Right Promise covers the installation, and we document the base condition with photos before we cover it.

DIY or Call Us?

A homeowner can safely assess what’s failing: lift one paver at the problem edge with a flat pry bar, photograph the base layer, and measure the paver thickness with a tape. If you see clean aggregate base and the paver is 60mm, it’s likely a Classic line; if the surface shows a distinct wear layer over gray concrete body, it’s Premium and needs OEM matching.

Where DIY goes wrong is in the base repair. Removing and relaying pavers without plate-compacting the base in lifts, or without checking for the proper 1/4-inch-per-foot drainage slope, produces the same failure in 18 months. The compactor rental is $90, the 3/4″ crushed aggregate is $45 per ton, and the skill is in reading the grade - we’ve fixed enough homeowner relay jobs in Pasadena’s Madison Heights and Chapman Woods to know the pattern. For base work or any permeable system, call us. For a simple sand refresh on a sound base, a careful owner can manage it.

Write it down before you build it - scope first, surprises later. Call (562) 203-4508 to schedule your free estimate; we’ll photograph the base, name the Unilock series, and deliver a written price before any work starts.
