Unilock Construction in North Tustin, CA | Sycamore Contractors
We install, repair, and replace Unilock paver driveways, patios, and walls across North Tustin, CA, and also provide Unilock in Tustin proper. Sycamore Contractors is an independent Unilock service provider, which means we work for you, not the manufacturer. What makes our Unilock work different in North Tustin comes down to one thing: this unincorporated community answers to OC Public Works instead of a city building department, and that changes how hardscape projects get planned, permitted, and built. Call (877) 265-6284 for a free estimate.
Why North Tustin Residents Choose Us for Unilock Service
We’ve spent enough time on Unilock service in Orange County hillsides to know which pavers hold up under the Santa Anas and which base designs fail after two wet winters. North Tustin specifically has its own rhythm: big lots, mature trees, older ranch-style homes, and drainage patterns that rarely behave the way a flat tract does. Nate Calloway, our owner, learned the construction trades at Palomar College’s construction technology program and spent nearly two decades running crews before starting Sycamore. He’ll tell you the same thing we all believe: paver work is only as good as what’s underneath it. That’s where most Unilock failures in North Tustin actually start.
We’re a full-scope general contractor, which matters more than people realize when a driveway replacement ties into a drainage fix, a retaining wall, or a patio rebuild. One contract, one team, one point of accountability. We bring brand-name options, you make the final call.

Common Unilock Construction Problems We Solve in North Tustin
Here are the five failure patterns we see most often on Unilock installations in North Tustin, and what’s actually causing each one:
- Efflorescence and color fading on older Brussels Block. The combination of intense UV exposure and the drying effect of Santa Ana winds draws salts to the surface of the paver over years of service. The chalky white residue isn’t damage to the paver, but it sure looks like it. We clean, treat, and re-sand these installations regularly.
- Base settlement and paver shifting on hillside lots. North Tustin’s slopes run up into the Santa Ana Mountains foothills, and many homes sit on expansive soils that swell and shrink with moisture. When the base wasn’t engineered for that movement, pavers sink or rotate. We see this most often on older driveways where the original installer skipped a proper aggregate subbase.
- Edge restraint failure. Without a solid perimeter, pavers migrate outward under repeated wheel loads and wind-driven rain. North Tustin’s long driveways on sloped terrain put constant pressure on the edges, and once the restraint lets go, the whole field starts to drift.
- Joint sand erosion and weed growth. Santa Ana winds push dust and grit into paver joints, which breaks down sand over time. Once the joints open up, weeds and ants move in. Reapplying polymeric sand every few years is cheap insurance; ignoring it isn’t.
- Drainage conflicts with county requirements. We’ve fixed several Unilock patios where the original installer didn’t account for impervious coverage limits or slope drainage rules. The county flags it during a later remodel inspection, and the homeowner is left with a patio that has to be partially rebuilt. We’ll talk about this more below.
Unilock Service in North Tustin: What Local Conditions Mean for Your Equipment
North Tustin is an unincorporated island of custom and semi-custom homes surrounded by incorporated Orange County cities. That jurisdictional fact isn’t trivia; it directly affects your Unilock project. Any paver driveway or patio that alters lot drainage or changes the amount of impervious surface on your property must go through OC Public Works for grading and drainage review. Neighboring Unilock in Villa Park and Tustin proper handle many hardscape permits over the counter. North Tustin does not. If you live in the hillside areas off Newport Avenue or along the older streets feeding into Cowan Heights, expect a longer timeline and possibly an engineered drainage plan, even for what feels like a modest patio addition. We handle this paperwork as part of our scope, because we’ve been through it enough times to know what OC Public Works reviewers look for. It’s not a reason to skip the project, but it is a reason to use a contractor who’s done it before.
Unilock Models & Products We Service in North Tustin
We install and repair the Unilock lines most common on North Tustin properties: Brussels Block, Brussels Dimensional, Town Hall, and Beacon Hill. For repairs and additions, we source OEM Unilock pavers to keep color and dimensional consistency tight, especially on older Brussels Block installations where the manufacturing pigments have naturally shifted over the decades. When OEM polymeric sands or edge restraints are hard to source or overpriced, we use high-quality aftermarket equivalents that meet the same performance spec. We also stock common paver sizes and joint sands locally, which means faster turnaround for North Tustin repairs.

AfterUnilock Service Pricing in North Tustin
Here are the two most common Unilock project types we quote in North Tustin, with the market-calibrated ranges we work within:
| Project Type | Typical Range |
|---|---|
| Paver Driveway Installation | $7,000 – $18,000 |
| Paver Patio Installation | $3,500 – $11,000 |
What moves the number is the base work, not the pavers. A hillside lot that needs deeper aggregate excavation, a channel drain, and OC Public Works drainage review will land at the higher end of the range every time. Flat, well-draining lots? Lower. A free estimate with us includes an on-site look at your existing drainage and a written line-item quote, so you can see exactly where the money goes. Call (877) 265-6284 to schedule one.

FAQs – Unilock Construction in North Tustin
Straight answers to the questions we hear most from North Tustin homeowners.
Yes, if the project changes lot drainage patterns or increases impervious coverage, which most driveway replacements do. Because North Tustin is unincorporated, the permit goes through OC Public Works, not a city hall counter. We handle the application, plans, and inspections as part of our scope. Call (877) 265-6284 and we’ll tell you early whether your specific project will trigger a grading review.
Unilock pavers handle the heat well, but the winds are the real test. The wind itself doesn’t harm the pavers; it’s the wind-driven dust and debris that erode joint sand and accelerate surface wear. High-quality polymeric sand and a properly compacted base do more for wind resistance than any paver choice. We design North Tustin installs with that in mind from day one.
That chalky appearance is efflorescence, a natural mineral deposit drawn to the surface by moisture and evaporation. It’s common on older Brussels Block installations in North Tustin because of the dry, hot conditions. The good news: it’s treatable and almost never means the pavers need replacement.
Usually, yes. We source OEM Unilock pavers for repairs and additions so the color and dimensions match. On older installations, there may be slight pigment variation from the original batch, but we’ll show you a sample before we commit. That’s part of the estimate.
A sloped lot needs at minimum a deeper aggregate subbase, proper compaction in lifts, and a drainage plan that moves water away from the paver field. On hillside properties, we often add a channel drain to satisfy OC Public Works’ drainage review. Skipping the base work is the fastest way to a patio that shifts within two seasons. Call (877) 265-6284 and we’ll walk your specific slope and drainage with you.
