Unilock Driveway & Pavers: The West Covina Owner’s Guide
We install and repair Unilock paver driveways and walkways throughout West Covina, with full paver driveway installations running $7,000 to $18,000 depending on square footage, base condition, and paver style. Most partial repairs, like a settling section or edge restraint failure, land between $1,500 and $4,500. You’ll usually notice the problem before you can name it: a paver that rocks underfoot, a low spot that holds water after rain, or a border that’s starting to wander toward the lawn.
Unilock pavers are the premium pick in southern California for a reason – they handle our dry summers and surprise winter downpours better than poured concrete because the joints flex instead of crack. But even the best paver system depends on what’s underneath it. In West Covina, where some neighborhoods sit on expansive clay that shifts with moisture, the failure usually isn’t the paver itself. It’s the base compacting unevenly, an edge restraint letting go, or polymeric sand washing out of the joints. Fix the cause and the paver surface stays put for decades.
Which Unilock Models This Applies To
Unilock runs several paver lines, and the compatibility question matters more than most homeowners expect. The three we handle most in West Covina are the EnduraColor series (Richcliff, Courtstone, Mattoni), the Elegance series, and the U-Cara multi-piece wall system. Each uses different joint widths and thicknesses, so a Richcliff paver from one batch won’t swap cleanly into a Courtstone layout without re-cutting the pattern.
Here’s the gotcha most people miss: Unilock pavers are made in specific thicknesses – typically 60mm for driveways and 50mm for patios and walkways. If someone installed a patio-grade paver under vehicle weight, that’s your failure point. We always check thickness before quoting a driveway repair in West Covina, because the wrong paver under a car or truck won’t just crack, it’ll grind down over time. As for OEM versus aftermarket, Unilock’s color blending is proprietary. A “close enough” paver from another brand will show within two years as UV light fades each material differently. For full driveway installs, we use Unilock products from authorized distributors. For small patch jobs, we match existing pavers by color code and batch when possible.
One more thing worth knowing: Sawyer Remodel West Covina is an independent contractor – we’re not affiliated with Unilock, but we’ve installed and repaired their products across West Covina for years, so we know the quirks of each series.

Signs Your Unilock Driveway & Pavers Is Failing
- Rocking or wobbling pavers underfoot. The base layer beneath that paver has compacted unevenly or washed out. Ignore it and the paver will crack along its weakest edge within a season.
- Standing water pools in one area after rain. That’s a low spot in the base, not the paver surface. Water is the number one enemy of any paver system, and in West Covina’s clay-heavy South Hills neighborhoods, trapped water accelerates base erosion fast.
- Edge pavers shifting or dropping onto the lawn. The edge restraint – the plastic or aluminum strip that holds the outside row – has failed or was never installed. Once the edge goes, the rest of the field starts creeping outward within months.
- Joint sand disappearing between pavers. Polymeric sand should stay firm between joints. If it’s powdery or missing after a season, water is getting under the pavers and washing out the bedding layer.
- Visible cracks running through multiple pavers in a line. That’s a structural base failure underneath, not a bad paver. Replacing just the cracked pieces without fixing the base will buy you a year, maybe two.
Replacement Cost & What’s Included
For a full Unilock driveway install in West Covina, plan on $7,000 to $18,000. The spread depends on square footage, access for excavation equipment, and whether the existing base can be reused or needs to be dug out and rebuilt. A standard two-car driveway in a typical West Covina lot runs between $9,000 and $14,000 with a proper compacted base, edge restraints, and polymeric sand joints.
Partial repairs are more surgical. A 100-square-foot settling section we can lift, re-grade the base, and reset the same pavers for $1,500 to $3,000. Edge restraint replacement along one side runs $800 to $2,000. Every quote we give in West Covina is a written line-item price before any work starts – the number you see is the number you pay, and our 365-Day Done Right Promise covers the workmanship for a full year after we close the job.
The part you’re paying for isn’t just the paver. It’s the excavation, the base material (typically 4 to 6 inches of compacted aggregate in our area), the bedding sand, the pavers themselves, edge restraints, and joint sand. We don’t bury labor charges in the materials line.
DIY or Call Us?
Resetting a single paver that’s rocking? You can absolutely pull it, add a bit of bedding sand, and tap it back down – that’s a Saturday morning job with a rubber mallet and a level. The danger zone starts when you’re looking at a section bigger than about 10 square feet, or if the paver lines are shifting at the edges. That means the base itself has failed, and no amount of surface patching will hold.
There’s also a safety angle people don’t think about until it’s too late: a settled paver driveway means an uneven walking surface and a trip hazard at your front door, and if you’re lifting pavers without knee pads and a proper lifting technique, you can strain your back faster than you’d think. Luca Romano has seen enough DIY paver repairs in West Covina that made the original problem worse – because the owner didn’t compact the base, the fix settled again within six months. If you’re not sure what you’re looking at, call us at (341) 217-4204 and we’ll walk you through what we’d check on-site. Good work shows. Bad work shows up later.

AfterHow long do Unilock pavers last in West Covina?
A properly installed Unilock driveway with a solid base will last 25 to 40 years in West Covina’s climate, though the surface pavers themselves may show UV fading or wear after 15 to 20 years. The lifespan killer in our area isn’t the sun – it’s water getting under the pavers and destabilizing the base. If you see standing water or sinking sections, call (341) 217-4204 to get eyes on it before the damage spreads.
Can you repair individual Unilock pavers instead of replacing the whole driveway?
Yes, we replace individual damaged pavers all the time, and for small areas it’s a fast, affordable fix. The catch is color match – Unilock’s blends are proprietary, so an older paver that’s been sun-faded won’t match a new one from a different batch. When you call (341) 217-4204, we’ll assess the area and tell you honestly whether a patch will blend or whether you’re better off doing a larger section.
How long does a Unilock driveway replacement take in West Covina?
A typical two-car driveway replacement takes 3 to 5 working days from excavation to final joint sand, assuming we’re not fighting weather or discovering a bad base that needs deeper excavation. A partial repair like edge restraint replacement is usually done in one day. We’ll give you a written timeline before we start, and we stick to it.
Do you stock Unilock pavers locally or do I need to order them?
We source Unilock pavers through authorized distributors in the West Covina area, which means we can usually have your exact paver style and color on-site within a few days. We keep common repair materials – bedding sand, polymeric sand, edge restraints – ready to go, so small repairs can often happen same-week. Call (341) 217-4204 and we’ll check availability for your specific paver line.
