Unilock Construction in Ontario, CA | Penhallow Remodeling Riverside
Unilock paver installation and repair in Ontario typically runs $3,500 to $18,000 depending on square footage, base condition, and whether we’re working around a slab foundation or an expansive clay patio. We’re an independent Unilock service provider, not a manufacturer authorized dealer, which means we answer to you, not a brand rep. The thing that makes our Unilock work different here is simple: we know what Ontario’s clay-heavy soil and 100°F summers do to paver bases, and we build for it from day one. Call (341) 895-1170 for a written quote.
Why Ontario Residents Choose Us for Unilock Service

Trevor Nash has spent the better part of two decades doing construction work across the Inland Empire, and his crew has put in real hours on projects throughout Riverside, including jobs in the Arlington neighborhood where older homes keep you honest about what’s behind the walls. That same honesty carries over to our work as a General Contractor - Ontario for Unilock projects. We don’t guess at base depth or edge restraint. We measure, we dig, and we give you a number before we pick up a tool, that’s just how this works.
What does that mean for your paver patio or driveway? It means we show up when we said we would, we use genuine Unilock pavers sourced through local distributors, and we match the color, size, and finish from the original lot. Unilock’s color blends vary batch to batch, and if you’ve ever seen a patio where half the pavers are one shade and half are another, you know why that matters. We do too.
Every job gets a written price before any work starts. Not a ballpark, not a verbal range, a number you can hold us to. And every job carries our 365-Day Done Right Promise: if the work fails inside the guarantee period, we come back and fix it at no charge. We also offer a free second visit if a repair fails. No service call fee, no re-inspection charge. That’s the Kingswell standard, and it’s been the standard since 2004.
Our technicians are background-checked and arrive in uniform. A live person answers the phone 24/7, not a voicemail maze. You’ll never wonder who’s walking up your driveway.
We’re Unilock sales & service specialists in the true sense: we know these pavers from base to surface, and we don’t hide behind fine print.

Common Unilock Construction Problems We Solve in Ontario
- Edge restraint failure at driveway aprons. Ontario’s 1950s-to-1980s housing stock sits on slab foundations, and where those slabs meet paver aprons, lateral movement is common. Without proper edge restraint, the pavers drift, joint sand washes out, and the edge starts to crumble. We install aluminum edge restraint and recompact the base so the pavers stay where they belong.
- UV fading on dark Beacon Hill and Brussels Block pavers. Ontario’s summer heat regularly pushes past 100°F, and that accelerates UV fading on darker Unilock color blends. If your pavers look washed out after a few summers, we can clean, seal, and restore the color without replacing the whole patio.
- Joint sand scouring from Santa Ana winds. Wide-joint Unilock pavers lose their joint sand when Santa Ana winds drive debris across the surface. Hollow joints mean weeds take root and pavers start shifting. We re-sand with polymeric sand and seal the surface so the joints hold.
- Differential settling from clay-heavy soil. Ontario’s expansive clay soils swell when wet and shrink when dry. Under paver patios, that causes heaving and lippage, adjacent pavers end up at slightly different heights. We excavate, install a proper compacted aggregate base with geotextile, and re-level the surface so it stays flat through rain and drought.
- Efflorescence and surface staining. White mineral deposits on Unilock pavers are common in Ontario because our water is hard and our soil is mineral-rich. Efflorescence is cosmetic, not structural. We clean and seal it rather than replacing pavers that are otherwise sound.
Unilock Service in Ontario: What Local Conditions Mean for Your Equipment

Here’s something you won’t read on a generic paver page: Ontario requires title 24 energy compliance for any new construction or major remodel, and paver installations around Ontario’s older stucco homes have to integrate with slab foundations and existing drainage patterns without triggering new energy audits. That’s a real constraint. A paver patio in Rancho Cucamonga or Fontana doesn’t carry the same design review pressure as one in Ontario’s historic downtown district along Euclid Avenue, where specific guidelines restrict front yard hardscape materials. Unilock pavers often meet those standards where a plain concrete slab would be denied outright. If you live near Euclid and want a front walkway or courtyard that passes review, Unilock is frequently the safest concrete alternative. Our service area covers all of Ontario service area neighborhoods, from the historic core to the northern and eastern expansion areas.
We pulled up a 400 sq ft Unilock Brussels Block patio behind a 1970s rancher on East B Street near the Ontario Airport as part of our Bathroom Remodeling in Ontario scope. The original contractor had used only a 2-inch sand base over expansive clay. The pavers had heaved up to 1.5 inches in the center and edge restraints had failed. We excavated, installed a 6-inch compacted aggregate base with geotextile, re-laid the existing pavers matching color from Unilock’s current lot, and added aluminum edge restraint and polymeric sand. That patio has stayed flat through two rainy seasons. That’s what building for Ontario’s soil actually looks like.
Unilock Models & Products We Service in Ontario
We install and repair all the major Unilock paver lines: Beacon Hill, Brussels Block, Richcliff, and Courtstone. Each one behaves a little differently under Ontario’s conditions. Beacon Hill’s tumbled finish hides wear well but shows joint sand loss quickly. Brussels Block’s larger format looks great on driveways but needs a deeper base to handle vehicle loads. Richcliff and Courtstone are better for patios and walkways.
For repairs, we use only genuine Unilock pavers sourced through local distributors. Matching color, size, and finish from the original lot matters because Unilock’s color blends vary batch to batch. If a paver is structurally cracked or spalled, we replace it. For minor surface efflorescence or fading, we recommend cleaning and sealing rather than full replacement. That’s the honest approach, and it’s usually the cheaper one too.

FAQs – Unilock Construction in Ontario
Yes, in most cases. We source genuine Unilock pavers through local distributors and match color, size, and finish against the current lot. Unilock’s color blends shift batch to batch, so we always pull physical samples and compare them against your existing pavers before ordering. Call (341) 895-1170 with a photo of your current patio and we’ll tell you if matching is realistic.
Unilock pavers use color pigments that are more stable than budget brands, but no paver is fully UV-proof. Darker tones like Beacon Hill’s charcoal and Brussels Block’s walnut show fading faster under Ontario’s direct summer sun. Sealing with a UV-stable sealer every few years slows it down considerably. If your pavers have already faded, we can clean and seal to restore depth without replacing the surface. Call (341) 895-1170 for a quote on cleaning and sealing.
Usually it’s the paver base, not the foundation. Ontario’s clay-heavy soil swells and shrinks with moisture, and a thin sand base over that soil will settle unevenly within a few years. Your foundation is almost certainly fine. We’ll excavate the sunken area, inspect what’s underneath, and rebuild the base properly. The free estimate includes that investigation. Call (341) 895-1170 to schedule.
Sometimes, but we don’t recommend it as a default. If the concrete is structurally sound and properly sloped, an overlay can work and save you the demolition cost. If there are cracks, spalling, or drainage problems, laying pavers over it just delays the failure. We’ll assess your driveway during the free estimate and give you an honest answer either way. Call (341) 895-1170.
Frequently yes. Ontario’s historic downtown has design review guidelines that restrict front yard hardscape materials, and Unilock pavers often meet those standards where a plain concrete slab would be denied. They look more period-appropriate, they’re permeable when installed correctly, and they satisfy the review board’s preference for traditional materials. If you’re planning front yard work near Euclid, call (341) 895-1170 and we’ll help you understand what the guidelines require before you commit to a design.
