Unilock Construction in Fontana, CA | Mason Remodeling
Unilock paver and wall projects in Fontana need a crew that respects hard clay soil and 100°F summers, because those two factors decide whether a hardscape lasts five years or twenty-five. Mason Remodeling provides independent Unilock installation and repair across Fontana, not manufacturer-authorized work, and that matters: our loyalty is to your driveway or patio, not to a corporate warranty department. Call (803) 680-2547 for a written estimate on paver driveways, patios, and retaining walls. We serve the whole Fontana area, from Sierra Lakes to Southridge.
Why Fontana Residents Choose Us for Unilock Service

Most Fontana homeowners don’t need a Unilock dealer. They need someone who has pulled up pavers that shifted after our clay soil expanded in winter rains and contracted in August heat. Our crews have installed and repaired Unilock hardscapes across the Inland Empire for years, so we know how Brussels Block holds up under our UV, how Ledgestone fades when it isn’t sealed, and when a repair beats a full replacement. We also provide Unilock repair in Rancho Cucamonga.
Isaac Pruett, our owner, grew up in the San Fernando Valley and trained in construction technology at Los Angeles Trade-Technical College. He has spent nearly two decades remodeling homes across the region, and he still checks edge restraints and base compaction on every paver job before he calls it done. That habit matters here. We quote Unilock work with OEM pavers and wall blocks when patching an existing surface, and quality aftermarket polymeric sands and sealers where they perform as well or better. You get a written price before anything starts, and every crew member arrives with a photo ID badge, in uniform, with their name and photo sent to you beforehand. That is the Threshold Standard, and it is not optional on a Fontana job.

Common Unilock Construction Problems We Solve in Fontana
The failures we see in Fontana are not random. They follow from our soil, our water, and our sun, and they repeat from one neighborhood to the next. Here are the five most common, each tied to what actually happens on Fontana properties.
- Efflorescence staining on Unilock Brussels Block pavers. Fontana water is hard, which means mineral salts ride up through the paver surface and leave chalky white residue when the moisture evaporates. In summer, that evaporation is brutal, and the staining gets set fast. We clean the efflorescence and apply a breathable sealer to keep it from returning.
- Edge spalling and chipping on Unilock Town Hall slabs. Those large-format slabs expand and contract as Fontana swings from 100°F days to cool desert nights. Without space for movement, the edges chip like broken pottery. We repair by re-seating and replacing damaged units, and we re-cut joints so the next heat wave doesn’t repeat the pattern.
- Settlement and shifting of Unilock Beacon Hill retaining walls. Fontana sits on expansive clay. Water in winter makes the clay swell; summer heat bakes it into rock. That cycle pushes and pulls at wall footings and block courses. We rebuild with geogrid reinforcement and drainage that gives the soil somewhere to do its worst without moving your wall.
- Color fading and surface degradation on Unilock Ledgestone walls. UV radiation at our elevation dulls unsealed Ledgestone within a couple of years. The sealer isn’t cosmetic; it is what keeps the color in and the surface stable. We seal every Ledgestone install, and we re-seal older walls that have gone chalky or gray.
- Paver driveway sinkage from poorly compacted base. A paver driveway in Fontana will sink in patches if the base material wasn’t compacted in lifts to at least 95% density. We excavate deeper than most crews, run a plate compactor on every lift, and add a flexible edge restraint so the perimeter doesn’t drift.
Unilock Service in Fontana: What Local Conditions Mean for Your Equipment
Fontana’s expansive clay soils and summer temperatures that routinely exceed 100°F cause Unilock pavers to shift and crack more than in coastal cities. The same conditions affect Riverside Unilock service areas. Look at any paver driveway in the Sierra Lakes or Heritage neighborhoods after two or three summers: the joints open up, the edge rows wander, and high-traffic spots start to cup. The reason is simple. Clay swells when wet and shrinks when dry, so the ground under your pavers never stops moving. If the base was compacted too thin, too dry, or too fast, that movement telegraphs straight up through the surface. We compact every base lift to 95% Proctor density, add a flexible edge restraint that can move a few millimeters without cracking, and use open-graded base where drainage matters. That is the difference between a paver patio that reads flat in year ten and one that looks like a skate park by year four. You will not find that level of local detail on a generic Unilock product page.
Unilock Models & Products We Service in Fontana
We install and repair the full Unilock range common in Fontana yards: Brussels Block, Beacon Hill, Town Hall, and Ledgestone. When we match an existing hardscape, we use OEM Unilock pavers and wall blocks. The color blend and texture have to match what is already in the ground; aftermarket copies rarely do. For jointing and sealing, we stock high-grade polymeric sands and penetrating sealers from brands we have tested in Fontana’s heat and clay, not whatever is cheapest at the local supply yard. Because we know which units are in stock at Inland Empire distributors, we can usually quote a repair or replacement within a day and schedule the work faster than a crew driving from out of the area. That local sourcing also lets us handle Unilock in San Bernardino without long wait times.

FAQs – Unilock Construction in Fontana
Yes, we can match most Brussels Block color blends using OEM Unilock pavers sourced from Inland Empire distributors. The challenge is age and weathering; a 15-year-old paver has faded in our sun, so a brand-new unit will look brighter. We can blend aged and new pavers across the repair area so the patch does not read as a square badge of new material. Call (803) 680-2547 and we can look at photos or schedule a visit.
We excavate the base deeper than standard practice, compact every lift to 95% density, install geotextile fabric to separate the base from the raw clay, and add a flexible edge restraint around the full perimeter. That combination keeps the clay’s swelling and shrinking from telegraphing up into the paver surface. For heavy driveways we use a stronger grid system.
Spring and fall, when daytime temperatures sit between 50°F and 80°F, are ideal for sealing in Fontana. Summer heat causes the sealer to flash-dry and streak before it levels, and cold winter nights slow curing. We typically schedule sealing jobs in March through May and again in October and November.
Yes. Every Unilock installation from Mason Remodeling carries our written guarantee, which runs 365 days from the completion date and covers workmanship defects. What it excludes, in plain terms: normal wear, color fading beyond what the paver’s own warranty thresholds allow, and damage from soil movement beyond normal seasonal cycles. If anything we installed fails within that year, we come back at no charge.
Usually not as a permanent solution in Fontana. Our clay soil flexes under concrete, and if we lay pavers on top, that flexing cracks the pavers within a few seasons. There are cases where an overlay works if the slab is intact and has proper drainage, but those are exceptions. In most Fontana driveways, we remove the concrete, excavate down past the clay layer, and build a proper base. That is what prevents the sunken or shifted driveway you see on other properties.
Know who’s coming, know what it costs, know it’s backed up – everything else is just noise.
