Unilock Construction in Orange, CA | Milpitas Construction
We provide independent Unilock paver and wall installation and repair across Orange, from Old Towne bungalows to newer foothill properties. The thing that sets our Unilock work apart here is simple: we know the Historic Preservation Design Review process on pre-1940s homes inside and out, so your paver project doesn’t stall at the permit counter. If you’re planning a Unilock driveway, patio, or retaining wall in Orange, call (877) 752-4194 and we’ll walk you through what the city will actually ask for.
Why Orange Residents Choose Us for Unilock Service
Unilock pavers aren’t interchangeable with generic concrete blocks, and we treat them that way. Our crew has installed and repaired Brussels Block, Beacon Hill, Umbriano, and Olde Quarry profiles across Orange County — including Unilock repair in Tustin — long enough to know which ones hold up on clay soil and which ones fight you during a Santa Ana wind event. Ken Stafford, our owner, grew up around tradespeople who kept their word and their work clean, and that’s the standard we bring to every paver job in Orange.
We’re not authorized by Unilock, and we won’t pretend otherwise. What we are is honest about it. We follow manufacturer installation guidelines, use OEM components when they’re available, and when a color’s been discontinued, we’ll tell you that too and source a quality aftermarket match. Orange homeowners call us because we give straight answers about what will and won’t work on their specific property.
From your first call to the final compaction pass, you get one crew, one point of contact, and no finger-pointing. We’re a full-scope Orange General Contractor, which means the same team handling your Unilock patio can also manage your roof, windows, or kitchen remodel if the project grows. Milpitas Construction carries access to more than 50 name-brand product lines, so when a paver job turns into a larger exterior renovation, we don’t hand you off to a stranger.

Common Unilock Construction Problems We Solve in Orange
- Efflorescence on dense pavers like Brussels Block. Orange’s semi-arid climate and irrigation runoff create the exact conditions for white mineral deposits to bloom across paver surfaces. We see it constantly on older Orange properties where sprinklers overspray onto walkways. Cleaning it takes the right product and technique; sealing too early locks it in permanently.
- Joint sand erosion and paver shifting from Santa Ana winds. Those fall wind events don’t just rattle windows. On exposed driveways in Orange’s east-side ranch tracts, sustained wind strips polymeric sand from joints over a few seasons, and pavers start drifting. We recompact, re-sand, and when the base is shot, we rebuild it properly.
- Color fading on older Umbriano pavers. Umbriano has a beautiful granite-like finish, but intense Southern California UV exposure takes a toll. After enough Orange summers, colors dull unevenly and surface wear shows. If the base is sound, we can replace faded sections; if the fading is widespread, we’ll tell you honestly that full replacement makes more financial sense.
- Edge restraint failure and settling in clay soil. Older Orange neighborhoods, especially around the Chapman University corridor, sit on clay that expands and contracts with moisture. Without solid edge restraints, pavers creep outward and the whole surface sinks. We fix this by excavating, addressing drainage, and reinstalling with proper edge confinement.
- Water pooling against foundations. A settled paver patio or driveway channels water toward the house instead of away from it. In Orange’s historic districts, that water hits 1920s foundations that don’t appreciate the attention. Regrading the base and installing permeable joint systems fixes the drainage and protects the structure.
Unilock Service in Orange: What Local Conditions Mean for Your Equipment
Here’s something out-of-town contractors miss when they quote Unilock work in Orange. In Old Towne Orange, any new hardscape visible from the street on a pre-1940s home requires a Certificate of Appropriateness from the Historic Preservation Design Review. That’s not a boilerplate permit. It’s a design review that can add weeks to your timeline and often dictates specific paver colors, patterns, and edge treatments to match the Craftsman or Spanish Colonial Revival character of the home. We recently completed a Unilock Brussels Block driveway replacement for a 1920s bungalow near the Plaza. The existing pavers had settled and were sending water toward the garage. We got the historic approval, removed the old base, regraded for proper drainage, and installed new pavers with a permeable joint system to handle runoff. That project took longer than a standard driveway replacement, and anyone who quotes you a fast turnaround in Old Towne without mentioning design review is either new to Orange or hoping you won’t notice the delay later.
If your home sits outside the historic overlay, your Unilock project moves faster, but the soil and climate still demand attention. Orange’s native clay wants to move, and the fall winds want to erode whatever you put on top of it. We plan bases accordingly.
Unilock Models & Products We Service in Orange
We install and repair the core Unilock residential lines most common in Orange yards: Brussels Block for driveways and sturdy walkways, Beacon Hill for high-end patios with multiple paver sizes, Umbriano for that smooth granite-like finish, and Olde Quarry for a more textured, quarried-stone look. When OEM pavers and wall components are available, we use them. When a color’s been discontinued or Unilock has shifted production, we source aftermarket substitutes that match in size, thickness, and color fastness. We don’t slap in whatever’s on the shelf at a big-box store and call it a match. For Orange projects, we keep a working stock of base materials, edge restraints, and polymeric sand locally, so we’re not waiting on freight to start your patio. Our full Unilock sales & service page covers what we stock elsewhere in Orange County.

FAQs – Unilock Construction in Orange
Yes. If your home is pre-1940s and within the Old Towne Orange Historic District, any street-visible hardscape including a paver driveway or walkway requires a Certificate of Appropriateness through the Historic Preservation Design Review. Start early; review timelines can stretch a project by several weeks. We handle the application and documentation as part of our Orange Unilock work. Call (877) 752-4194 to talk through your property’s specific situation.
Sustained fall winds strip fine joint sand from exposed paver surfaces and can loosen edges over multiple seasons. We use polymer-stabilized joint sand and properly installed edge restraints to hold against Orange’s wind conditions. It’s one of the first things we check on existing paver failures.
Yes, if the color and profile are still in production we use OEM Unilock pavers. For discontinued colors, we source aftermarket options that match in size, texture, and fade characteristics. We’ll show you samples in daylight before committing so there are no surprises. Call (877) 752-4194 and we’ll bring matching options to your Orange property.
For a standard 300 – 500 square foot patio outside the historic overlay, expect excavation, base prep, installation, and compaction to run 3 to 5 working days. In Old Towne Orange, add design review time to the front end, which varies by city workload. We’ll give you a timeline in writing before work starts.
Efflorescence is that white mineral haze that appears on pavers in Orange’s dry, irrigation-heavy conditions. We treat it with the right cleaning process, not acid that damages the surface, then follow with sealing only after the moisture cycle settles. Most efflorescence clears with proper treatment and time; if it keeps returning, there’s usually a drainage or irrigation issue underneath the pavers. Call (877) 752-4194 for an assessment.
