We provide independent Unilock specialists for paver and retaining wall service across Redlands, including ZIP codes 92373, 92374, and 92375.

We’re not manufacturer-affiliated, so our recommendations are based on what actually holds up in your neighborhood, not a sales quota. Call (877) 688-9930 for a free estimate on any Unilock project, from paver driveways to walls and patios.
Why Redlands Residents Choose Us for Unilock Service
Brent Calloway, our owner and general contractor, has spent nearly three decades working on homes throughout Southern California, and he runs our Redlands Unilock work the same way he runs everything else: diagnose the real problem, fix it from the base up, and don’t waste material or the client’s time. Brent’s grandfather was a carpenter who never wasted a board, and that same instinct carries into our paver work. If a Unilock patio in Redlands is heaving, we don’t just re-sand the joints and call it done. We find out why the base is moving, correct the drainage, and then restore the surface. We’ve installed and repaired Unilock Brussels Block, Beacon Hill, and Richcliff pavers across Redlands’ vintage core and the newer east-side subdivisions, so we’ve seen how each product line behaves under this specific climate. And because we’re a full-scope general contractor, not a paver-only shop, we catch problems other installers miss, like drainage issues that trace back to roof runoff or foundation grading. One contractor, every system.

Common Unilock Construction Problems We Solve in Redlands
- Efflorescence and salt migration on Brussels Block and Richcliff pavers. Redlands’ hot, dry summers pull moisture up through the paver, and when winter rains arrive, the cycle repeats and leaves a white, chalky residue. It’s especially common on older installations where the base drainage is marginal. We clean and treat the surface, but more importantly, we correct the underlying moisture path so it doesn’t come back in six months.
- Shifting and rutting in paver driveways on expansive clay. The clay soils common across Redlands expand when wet and shrink when dry, and on sloped east-side lots, water runs under the bedding layer and washes the base out from beneath the pavers. You’ll see low spots, sunken areas, or pavers that rock underfoot. We re-excavate, stabilize the subgrade, and rebuild with a compacted aggregate base that won’t wash away.
- Polymeric sand erosion after Santa Ana winds and storm runoff. Redlands gets hit with both. Wind scours the joints dry, then winter rain washes through whatever sand is left. Open joints let pavers shift and weeds take root. We re-sand with Unilock OEM polymeric material and check the edge restraints, because if the border lets go, the whole field starts moving.
- Color fading and surface scaling on older Unilock pavers. Intense inland sun takes a toll on the surface layer of pavers that have been down for fifteen or twenty years. Homeowners often assume it’s a manufacturing defect, but it’s UV wear. We’ll tell you honestly when a surface can be restored with cleaning and sealing, and when replacement makes more sense.
- Retaining wall lean and blowout on hillside properties. Unilock Estate Wall units are engineered well, but no wall survives poor drainage behind it. On Redlands’ hillside lots, we regularly find walls that were built without proper drainage gravel or weep holes, and the hydrostatic pressure has pushed them out of plumb. We rebuild with proper backfill and drainage so the wall stays put.
Unilock Service in Redlands: What Local Conditions Mean for Your Equipment
In Redlands’ historic core, around State Street and the Millionaires’ Row area, mature citrus and oak trees on old lots mean root-protection and grading permits often have to be cleared before any paver driveway or patio excavation begins. That’s a step that rarely applies in the newer east-side subdivisions, where lots were cleared and graded decades ago. If you’re planning a Unilock driveway in the 92373 ZIP, we factor the tree survey and city review into the schedule from day one, so the project doesn’t stall mid-excavation. On a 1920s Craftsman near State Street, we replaced a heaved Unilock Brussels Block walkway where oak roots had pushed the base out of level. We hand-excavated around the root zone, rebuilt the base with a permeable open-graded aggregate, and re-laid the original pavers with new edge restraints and OEM polymeric sand. The homeowner kept the vintage look, and the walkway now drains away from the foundation instead of toward it. That’s the Redlands historic-core reality: the tree stays, the house stays, and the pavers have to work around both.
Unilock Models & Products We Service in Redlands
We work with the full range of Unilock product lines you’re likely to find in Redlands: Brussels Block for driveways and walkways, Beacon Hill for a tumbled, vintage look that suits the Craftsman and Spanish Revival homes near downtown, Richcliff for a larger-scale contemporary feel on newer east-side builds, and Estate Wall for retaining walls and terrace steps. Our parts approach is straightforward: we use Unilock OEM polymeric sand and edge restraints where they match the existing system, and quality aftermarket base materials where they perform better in Redlands’ clay soils. We keep common joint sands and edge restraints on hand for fast turnaround on Redlands repairs, and we’ll tell you honestly when re-sanding and re-leveling a wall or patio is smarter than a full tear-out. Sometimes the existing pavers are in fine shape and only the base needs work. We won’t sell you a replacement you don’t need.

What drives the cost in Redlands is the same thing that drives everything here: the soil. Historic-core lots with tree roots and tight access take longer to excavate carefully. East-side hillside lots need more base stabilization and drainage work. A flat, clear lot in a newer subdivision is naturally faster. Your free estimate includes a site visit, soil assessment, and a written line-item quote, so you’ll see exactly where your money goes before you commit. Call (877) 688-9930 to schedule yours.

FAQs – Unilock Construction in Redlands
Yes, in most cases. Redlands requires permits for paver driveways that change the footprint, alter drainage patterns, or involve excavation deeper than the surface layer. On historic-core properties in the 92373 ZIP, you may also need tree-protection review and grading approval before work starts. We pull the permits and handle the inspections as part of the job. Call (877) 688-9930 and we’ll tell you exactly what your property requires.
That’s efflorescence, and it’s common in Redlands because of the wet-dry cycle between hot summers and winter rains. Moisture moves through the paver, brings mineral salts to the surface, and the water evaporates, leaving the white residue. It’s not a manufacturing defect. We clean it off and, more importantly, fix the drainage or base issue that’s feeding the moisture in the first place.
Usually, yes. Brussels Block is one of Unilock’s longest-running lines, and we can source matching pavers for most Redlands installations. There may be slight color variation between old and new batches, especially on UV-exposed surfaces, but we blend new pavers with the existing field so the transition is subtle. If the original color was discontinued, we’ll show you the closest alternatives and give you an honest recommendation on whether a full re-color or selective replacement makes more sense.
They hold up better when installed correctly, and that matters in Redlands because our expansive clay soils move. A monolithic concrete slab is rigid, so when the clay swells and shrinks, the slab cracks. Unilock pavers are flexible; they move with the soil and can be re-leveled without a full tear-out. The catch is that the base has to be built for clay. If it’s not, water gets under the pavers, the clay goes soft, and you get ruts and low spots. We build for that.
Fall and early spring are ideal. The ground isn’t baked hard, the Santa Ana winds haven’t kicked up dust and debris into the joint sand, and the winter rains haven’t saturated the soil yet. But honestly, we install year-round in Redlands. We adjust the base prep and sand application based on the season, and the pavers don’t care how hot the air is. Call (877) 688-9930 to talk about timing for your project.
