We’re not a Unilock factory operation.

And on these hillside lots, the base is where everything gets decided.

He’s the one who’ll walk your project before any work begins.

Why West Covina Residents Choose Us for Unilock Service
We have worked on enough Unilock installations in West Covina to recognize a Brussels Block patio that was laid on thin sand from across the street. Most contractors treat pavers like a surface job. We treat them like a structural one, because on these hillside lots above I-10, that’s what they are. Unilock sales & service is our core focus, and we carry that depth into every repair and new install we take on.
Isaac Pruett and our crew have been working throughout West Covina for years. We’ve handled paver jobs near Eastland Center, up in the hillside streets, and across the flatter ranch neighborhoods south of the freeway. Every crew member who arrives at your door is background-checked, identity-verified, and in a clean marked uniform with a photo ID badge. That’s the Threshold Standard we operate under. You’ll get the name and photo of your technician before the visit.
We also put our price in writing before any work starts. Not a rough verbal estimate that grows on the final bill. A written line-item quote. And every Unilock project we complete is covered by our 365-Day Done Right Promise: if something isn’t right within a year, we fix it at no charge.

Common Unilock Construction Problems We Solve in West Covina
These are the issues we see repeatedly across West Covina, and they’re tied directly to this city’s soil, grade, and sun exposure:
- Heaved and lipped pavers on hillside lots. The expansive clay above I-10 swells with winter moisture and shrinks in summer heat. That movement pushes pavers out of plane, creating lips and trip hazards. We see this constantly on Brussels Block installations where the original base wasn’t deep enough.
- Chalky, faded pavers on west-facing exposures. Courtstone and Town Hall units that catch afternoon sun and Santa Ana wind develop efflorescence and color fading faster than shaded areas. It’s cosmetic but it ages a patio ten years in three.
- Washed-out joint sand on sloped driveways. Winter rain running down steep West Covina grades scours sand from paver joints. Once the sand goes, the pavers start shifting. Driveway sealing and re-sanding are regular calls for us.
- Tilting Lineo Dimensional walls with no drainage. Original builders often skipped drainage gravel and weep holes. On clay slopes, water builds up behind the wall, and lateral pressure tilts or cracks the blocks. We repair these properly with drainage installed.
- Patchwork repairs that don’t match. We often get called after someone else patched a section with the wrong color or discontinued style. We match genuine Unilock replacements through local distributors and when exact match isn’t possible, we’ll tell you straight and recommend redimensioning.
Unilock Service in West Covina: What Local Conditions Mean for Your Equipment
On the hillside streets above I-10, West Covina contractors must contend with expansive clay soils that shift seasonally. That single fact dictates how we install and repair Unilock systems here. South of the freeway, the ground is flatter and more predictable. A standard 4 to 6 inch gravel base often does the job. But up on streets like Larkspur Lane, we excavate deeper, lay geotextile fabric, and compact a geogrid-reinforced crushed rock base to absorb the seasonal movement. When we skip that step, we get called back in two years to fix heaved pavers.
Up on Larkspur Lane, our crew removed a heaved Unilock Courtstone patio where the original builder had laid only 2 inches of sand. After excavating 8 inches, we installed a geogrid-reinforced crushed rock base and relaid the salvaged pavers, setting them back level and adding a compacted base that will handle the clay movement. That job lives in our heads because the pavers themselves were fine. The base had failed them.
Unilock Models & Products We Service in West Covina
We work on the full range of Unilock product lines common in West Covina neighborhoods:
- Brussels Block – the classic tumbled paver you see on driveways and patios across the city’s mid-century tract homes.
- Courtstone – a smaller cobble-style paver, popular for patios and walkways. We see a lot of these on hillside homes where the scale suits tighter lots.
- Town Hall – a larger format paver with clean lines, often chosen for modern remodels and driveway replacements.
- Lineo Dimensional Stone – a retaining wall block we service regularly. On West Covina slopes, drainage and geogrid reinforcement matter more than the block itself.
When repairs call for replacements, we source genuine Unilock units through local distributors, matched by color and style to preserve the existing pattern. If an older line is discontinued and exact match isn’t possible, we’ll tell you before we order anything. For adhesives, joint sand, and base materials, we use commercial-grade aftermarket supplies that meet or exceed Unilock’s installation specs.

FAQs – Unilock Construction in West Covina
Excavate deeper than standard: we go 8 to 10 inches on hillside clay, lay geotextile fabric, then compact a geogrid-reinforced crushed rock base before the bedding layer. The goal is a base that flexes with the clay instead of cracking under it. Call (707) 760-7579 if you need this done right.
That chalky film is efflorescence – mineral salts rising through the paver from moisture below. West Covina’s hard water and clay soils make it common. We clean it with specialized paver cleaners and reseal the surface to slow its return. The fix works, but on west-facing exposures with full afternoon sun, expect to reapply over time.
Yes, with the right base and joint stabilization. Courtstone handles the heat fine, but you’ll want polymeric joint sand to resist wind and rain washout, plus sealing to slow UV fading on that sun-baked exposure. Call (707) 760-7579 for an exact recommendation for your driveway.
Sometimes yes, sometimes no. If the blocks are intact and the tilt is recent, we can often excavate behind the wall, install drainage gravel and weep holes, and reset the blocks. If the wall has cracked or the footing has failed, a full rebuild is the honest answer. We’ll tell you which one you need before we quote, and the quote is always in writing.
Most paver patios in West Covina run $3,500 to $11,000 depending on size, slope, access, and whether we need to correct an old base. Hillside lots above I-10 land on the higher end. Call (707) 760-7579 for a free written estimate on your specific yard.
