Unilock Construction in Tustin, CA | Sycamore Contractors

We’re Sycamore Contractors, an independent construction crew installing Unilock pavers, walls, and hardscape systems across Tustin. We are not Unilock-authorized, and we won’t pretend to be. What we bring instead is the product knowledge and local excavation experience to handle the one thing that separates a Tustin Unilock job from anywhere else in Orange County: the environmental review shadow cast by the former MCAS Tustin hangars and the Legacy redevelopment.

Why Tustin Residents Choose Us for Unilock Service

We’ve installed Unilock pavers and wall systems in Old Town bungalows, Tustin Ranch tract homes, and a handful of Legacy-area properties where the paperwork outweighs the labor. That range matters. A paver patio behind a 1940s raised-foundation home off El Camino Real has a different base problem than a driveway apron in a 92782 HOA tract with expansive clay underneath. Nate Calloway, our owner, grew up in Temecula’s Redhawk neighborhood and spent two decades running crews across Southwest Riverside County before Sycamore grew into Orange County. He’ll tell you straight when a Brussels Block patio can be re-leveled and re-sanded instead of torn out, and when a base needs to come up because the soil under it never should have been built on in the first place. We use Unilock’s own compatible base, edge-restraint, and polymeric joint-sand systems rather than cheap aftermarket substitutes. Unilock sales & service is a core part of what we do, and our Tustin service area coverage means we’re familiar with every ZIP here: 92780, 92781, and 92782.

Common Unilock Construction Problems We Solve in Tustin

• Paver settlement and lippage on Old Town bungalow lots. Homes in 92780 frequently sit on raised foundations with unconsolidated fill and original clay soil. Walkways and driveway aprons that tie into old stoops start to step and rock after a few Santa Ana dry cycles because the base was never compacted to handle it. We pull the pavers, reset the grade, and add a proper aggregate base before re-laying the Unilock units.
• Efflorescence and joint-sand washout on west-facing patios in 92782. Tustin Ranch tract yards often have builder-grade concrete poured over expansive clay. When the long dry season shrinks that soil and joints lose their polymeric sand, you get white mineral staining and sand that blows out within a season. We re-sand and seal where it makes sense, and we’ll tell you when the base under the pavers is the actual problem.
• Edge-restraint creep and outward spread on paver driveways. This shows up most often on newer Tustin Ranch streets where a quick install skipped base depth. Without a glued-down edge restraint and a compacted base, paver driveways slowly spread toward the curb. We correct it by cutting back the edges, installing proper Unilock-compatible restraint, and re-setting the perimeter units.
• Wall-block staining and algae on north-facing retaining walls in Old Town. Tustin’s shaded alleys and older drainage paths push roof and yard runoff onto walls instead of piping it to daylight. Brussels Block and Beacon Hill walls hold up under the moisture, but the staining and algae growth make them look decades older than they are. We re-route drainage and clean or re-face the wall depending on what we find.
• Base failure from expansive clay under patios across Tustin. Tustin’s long dry season shrinks clay soil under slabs and paver patios alike. When the first winter rain comes, that soil swells and heaves whatever sits on top. The fix is almost always the same: excavate deeper than the original install, bring in proper aggregate, compact it in lifts, and lay the Unilock pavers on a base that drains instead of floats.

Unilock Service in Tustin: What Local Conditions Mean for Your Paver Project

The former MCAS Tustin blimp hangars sit on land now being redeveloped as Tustin Legacy, and the soil and groundwater across that footprint carry legacy military contamination. This is not a rumor and it’s not a worst-case hypothetical. It’s a documented environmental constraint that means any excavation, grading, or utility trenching for a paver driveway or patio inside the Legacy area can trigger environmental sampling and disposal protocols. A same-sized paver job in Irvine or Orange simply never sees that layer of review. For a Unilock paver driveway in the 92782 stretch of Tustin Legacy, that review adds cost and schedule before a single Brussels Block ever touches the ground. We’ve worked through that approval path and we know how to plan for it in the estimate, not spring it on you after we start digging. Meanwhile in Old Town’s 92780, the constraint shifts to old raised foundations, narrow side yards, and clay-heavy soil that needs a deeper, better-draining base than the original build ever had. Two Tustin ZIP codes, two completely different engineering realities.

On a raised-foundation bungalow off El Camino Real in Old Town Tustin, we pulled out a cracked original concrete walk and a heaving driveway apron and reset the grade with a thicker compacted aggregate base before laying Unilock in North Tustin Brussels Block in a running-bond pattern that met the original stoop without lippage. The lot’s expansive clay had shifted the old slab, so we added a glued-down edge restraint and a perforated drain to daylight behind the front stoop. The owner got a level, walkable entry that no longer ponds when the dry season gives way to the first winter rain.

Unilock Models & Products We Service in Tustin

We install and service the full Unilock residential hardscape line that makes sense for Southern California lots. Brussels Block and the Brussels Dimensional System handle most paver driveways and patios. Beacon Hill and Brisa wall systems cover low retaining walls and planter borders. Town Hall and Holland Stone pavers work well for walkways and small courtyard spaces. Seneca and Fortuna wall systems suit taller retaining walls. For parts and base work, we use Unilock’s own compatible edge restraint and polymeric joint sand rather than mismatched aftermarket edging from a big-box shelf. For Tustin turnaround, we keep common base materials and joint sands on hand so repairs don’t wait on a distributor shipment from further inland.

FAQs – Unilock Construction in Tustin

Do paver driveway or patio projects inside Tustin Legacy need environmental review because of the old MCAS Tustin base? Yes, they frequently do. Soil and groundwater across the former MCAS Tustin footprint carry legacy military contamination, so excavation, grading, and utility trenching for a paver driveway or patio inside the Legacy area can trigger environmental sampling and disposal protocols. A paver job in a neighboring city like Irvine or Orange never faces that layer of review. Call (877) 265-6284 and we’ll check your parcel before you commit to a scope.

Are you a Unilock-authorized installer? No, we’re not. Sycamore Contractors is an independent hardscape and construction crew. We install Unilock pavers and walls and we know the product line well, but we are not manufacturer-affiliated or authorized. We use Unilock’s own compatible base, edge-restraint, and joint-sand systems because they’re the right materials for the job, not because a company badge tells us to.

Do you use genuine Unilock parts and materials? Yes. We install Unilock’s own units and its compatible base, edge-restraint, and polymeric joint-sand systems. We don’t swap in aftermarket edging or off-brand sand to save a line item. For repair work on existing Unilock patios and driveways in Tustin, we source matching units whenever they’re still in production and tell you honestly if a color or line has been discontinued.

How long does a Unilock paver driveway or patio installation take in Tustin? Most residential paver driveways and patios in Tustin take one to two weeks from excavation to final compaction and joint sanding. Projects inside the Tustin Legacy footprint can stretch longer if environmental sampling is triggered. Unilock repair in Santa Ana and Old Town jobs with deep clay excavation also run toward the upper end of that window. We’ll give you a written schedule before we start, not after.

Which Unilock models do you cover? We install and service Brussels Block, Brussels Dimensional System, Beacon Hill, Brisa, Town Hall, Holland Stone, Seneca, and Fortuna wall systems. If you have an existing Unilock patio or driveway and you’re not sure of the exact line, we can identify it on a site visit and tell you whether re-leveling and re-sanding will beat a full replacement. Call (877) 265-6284 to schedule a look.

How much does Unilock paver driveway installation cost in Tustin? Paver driveway installation in Tustin runs $7,000 to $18,000 depending on the square footage, the condition of the base underneath, and whether your parcel sits inside the Tustin Legacy environmental review area. Paver patios run $3,500 to $11,000. Call (877) 265-6284 for an exact quote on your lot – estimates are free.
