Unilock Construction in Ontario, CA | Barrett &s; Sons Construction
We provide independent Unilock hardscape service across Ontario, from paver driveways to patios and walkways, as well as Rancho Cucamonga Unilock service. What sets our Unilock work here apart is simple: we know how these pavers behave on Ontario Ranch’s cut-and-fill lots and under Inland Empire heat. If your Unilock driveway is sinking near the garage or your patio joints are cracking after a 108°F week, call Barrett & Sons at (877) 610-1318. Tom Barrett has been laying and repairing hardscapes in Southern California since 1998, and we’ll give you a straight answer and a free estimate.
Why Ontario Residents Choose Us for Unilock Service
We’re not a manufacturer-authorized dealer, and we won’t pretend to be. We’re an independent Unilock service provider, which means we work for one person alone: the homeowner in Ontario who wants their driveway or patio done right, whether they need Kitchen Remodeling - Ontario or hardscape work. We use genuine Unilock pavers, matching edge restraints, and polymeric sand rated for the temperature swings this city deals with. Tom Barrett grew up in the San Fernando Valley and learned the trade at Los Angeles Trade-Technical College. We’ve spent 29 years building and repairing hardscapes across Los Angeles and the Inland Empire. When we quote an Unilock job in Ontario, it’s a written quote, and any change after that arrives as a written change order before work moves. You can look up our name, address, and license number. Ask anyone on your street, or look up the license number yourself.
Common Unilock Construction Problems We Solve in Ontario
- Base settlement and edge sinking in Ontario Ranch. The pads out there were cut-and-filled aggressively over former vineyard and dairy land. We regularly see Unilock pavers sink near garage aprons and along edges within just a few years of installation.
- Heat-induced paver expansion on unshaded driveways. July in Ontario means surface temps above 150°F. Pavers expand, and polymeric sand joints crack. We pull the old sand and re-joint with a G2 product rated for this heat.
- Efflorescence and surface staining from hard irrigation water. Ontario’s water leaves mineral deposits on Unilock surfaces after sprinkler runoff dries. We clean and, where needed, seal to hold off the chalky white residue.
- Weed growth and ant intrusion through sand joints. In the historic core’s mature neighborhoods, older paver systems often lack modern edging or separation fabric. Weeds and ants find the joints. We remove, re-edge, and re-joint properly.
- Drainage failure on patios after Santa Ana wind events. Fall winds push debris into paver gaps and clog drainage channels. A patio that holds water after a windstorm is a patio with a blocked joint system. We clear and repair it.
Unilock Service in Ontario: What Local Conditions Mean for Your Pavers
Here’s something you won’t read on a national Unilock page. Ontario Ranch’s rapid buildout happened on former Cucamonga vineyard and dairy land. Builders cut into the hills and filled the low spots fast. Many residential pads out there now show differential settlement within a few years. For Unilock owners, that means a driveway or patio that was perfectly flat on day one can develop waves and low spots as the fill underneath compacts unevenly. We don’t see this failure pattern in Ontario’s older neighborhoods, where homes sit on original native soil. Along Grande Vista Drive in Ontario Ranch, our crew replaced a settling Unilock Richcliff driveway after two years of sinking near the garage apron. We removed the pavers, compacted a new Class II road base to 95% Proctor, added geotextile separation fabric over the expansive clay fill, and reinstalled the Richcliff units with fresh G2 polymeric sand. The previous contractor had skipped base prep entirely. Now that surface drains correctly and stays level through summer heat. If your Unilock hardscape sits on Ontario Ranch fill, base prep is not optional.
Unilock Models & Products We Service in Ontario
We work on the full range of Unilock hardscape products. The models we see most around Ontario are Richcliff, Umbriano, Town Hall, and Hollandstone. Richcliff’s running-bond look shows up on a lot of Ontario Ranch driveways. Umbriano’s mixed surface is common on patios in the historic core. For repairs, we use genuine Unilock pavers and matching edge restraints so color and dimensions stay consistent. We stock the most common paver styles locally for faster turnaround on Ontario jobs, and we order specialty lines directly through our supplier network. Our parts counter isn’t a mystery brand off a van, and the same goes for Unilock sales & service we’ve offered across the region for years.

What drives the final number on an Unilock job in Ontario is base prep, site access, and whether we’re repairing or replacing a surface. The Ontario Ranch fill work costs more than a patio on native soil because we’re rebuilding the base, not just laying pavers. A repair on cracked polymeric sand joints is a fraction of a full driveway replacement. Your free estimate includes a written line-item scope with exact allowances, so the price you approve is the price you pay. Call (877) 610-1318 and we’ll come out, look at it, and put it on paper for you.

FAQs - Unilock Construction in Ontario
Ontario Ranch pads sit on aggressively cut-and-filled former vineyard and dairy land, which compacts unevenly over time and causes differential settlement under Unilock pavers. Older Ontario neighborhoods on original native soil don’t see this pattern. That’s why we add geotextile separation fabric and compacted Class II road base on Ontario Ranch jobs, which we don’t always need in the historic core. Call (877) 610-1318 for a free site assessment.
Yes. We use genuine Unilock pavers in the correct product line and color blend, plus matching edge restraints. The goal is a repair you can’t spot from six feet away. Bring us a photo or let us visit the site and we’ll identify the exact style, from Richcliff to Town Hall to Hollandstone. Call (877) 610-1318 to schedule a look.
The fix is removing the failed sand and re-jointing with a high-temperature-rated polymeric sand, typically a G2 product, after the pavers have been cleaned and reset. We don’t just sweep more sand on top, because it’ll crack again in the next 108°F stretch. Call (877) 610-1318 and we’ll quote your re-jointing job on the spot.
Santa Ana winds push leaf litter, dust, and fine debris into the joints and drainage channels of Unilock patios. Then the first rain after the wind plugs up the works. The fix is a full joint cleaning and re-sanding, plus drainage clearing. We do this all over Ontario every fall. Call (877) 610-1318 before the next wind event shows up.
If over 30% of the field has settled, we recommend full re-installation over continuous patchwork. Patching one low spot on badly compacted fill just moves the problem to the next joint. We’ve done enough Grande Vista Drive driveways to know. We’ll measure it, tell you straight, and give you a written scope either way. Call (877) 610-1318 for the honest answer.
