Unilock Construction in Hillsborough, CA | Iron Beam Contractors
We provide independent Unilock paver construction and repair across Hillsborough, from full driveway replacements to patio builds and settlement repairs, as your trusted Hillsborough General Contractor. What makes our Unilock work different here is that we plan every base, slope, and joint around Hillsborough’s tree-protection review process, expansive clay soils, and atmospheric-river drainage patterns before the first paver gets set. If you need Unilock work done right in Hillsborough, call us at (833) 756-5936 for a free estimate.
Why Hillsborough Residents Choose Us for Unilock Service
Unilock pavers are a premium hardscape product line, but the difference between a paver driveway that holds for 20 years and one that starts lipping in three comes down to what happens underneath. Our crews have laid and repaired Unilock Brussels Block, Turfstone, Beacon Hill, and Town Hall across Hillsborough’s sloped estate lots, and we’ve seen how each profile behaves when Peninsula rain saturates the subgrade. We’re independent Unilock specialists offering Unilock service in San Mateo County, which means we don’t claim Unilock authorization or warranty endorsement. What we do claim is real field knowledge: know the base spec, know the grade, know the drainage, and the surface takes care of itself.
Nolan Driscoll, our owner, grew up in the Friendly Hills area of Orange and spent enough afternoons at Santiago Oaks as a kid to understand soil, grade, and clay behavior from the ground up. He built Iron Beam Contractors on a simple principle: tell the homeowner exactly what’s in the ground before you open it up, not after. That matters in Hillsborough, where the answer underneath is often expansive clay with a redwood root running through it.

Common Unilock Construction Problems We Solve in Hillsborough
- Efflorescence on Brussels Block after damp Peninsula winters. Hillsborough’s cool, wet winters push moisture up through pavers, leaving white mineral deposits on the surface. We see it most often where pavers sit against north-facing estate foundations that never fully dry out. Cleaning it takes the right process; keeping it from returning takes addressing the drainage behind it.
- Joint sand washout and paver migration on sloped lanes. Atmospheric-river storms send a lot of water down Hillsborough’s private lanes quickly. When base compaction wasn’t engineered for the grade, we see joint sand wash out and pavers start to drift. The fix is more than sweeping in new sand; the edge restraint and base profile usually need rework.
- Subsidence and lipping over expansive clay. On tree-root-constrained lots, a sub-base that’s cut short will heave and settle unevenly as clay swells and shrinks with seasonal moisture. The pavers start to lip, and you feel it underfoot. Re-basing is the only real fix.
- Turfstone grid clogging with oak and redwood debris. Hillsborough’s mature canopies drop a steady load of leaves and needles. Turfstone grids fill up, infiltration dies, and water pools against driveways instead of percolating through. Seasonal clearing and re-speccing the fill material address it.
- Edge restraint failures on steep lanes. When storm runoff undermines the edge restraint on a sloped driveway, the entire field can start to creep downhill. We’ve reset more than a few Hillsborough driveways where the pavers were fine but the restraint system had failed quietly at the perimeter.
Unilock Service in Hillsborough: What Local Conditions Mean for Your Equipment
No, your pavers aren’t equipment. But the planning constraints around them in Hillsborough are unlike anywhere else on the Peninsula. On many Hillsborough estates the mature oak and redwood canopy triggers tree-protection review that locks the site plan before a paver driveway and patio layout can be finalized. You can’t just mark out a rectangle and start cutting base. We bring an arborist to flag root zones before we design the base footprint around them, because a protected redwood root zone doesn’t move no matter how much you want that driveway to be three feet wider. In Hillsborough, the tree ordinance often dictates the entire hardscape layout, and a contractor who doesn’t plan for that is going to hand you a redesign bill after the plans get kicked back. If the structure makes sense on paper, it’ll hold in the field. If it doesn’t make sense on paper, we fix it before we touch a beam.
Unilock Models & Products We Service in Hillsborough
We work across the Unilock lines most common in Hillsborough’s estate-scale projects. Brussels Block, with its tumbled edges and varied face, is the paver we see most on older Hillsborough driveways and walkways. Beacon Hill and Town Hall show up on newer tear-down rebuilds where the architecture leans more formal. Turfstone is the pick for overflow parking and fire-access strips, though maintenance reality differs under a dense canopy. When we repair or extend a Unilock field, we source genuine Unilock pavers and matching units where available to keep color and thickness consistent with the existing field, and we use quality polymeric joint sand and edge restraint rather than cheap substitutes. For Hillsborough jobs, we plan material delivery around the narrow private lanes that make staging a logistical puzzle on its own.

AfterUnilock Service Pricing in Hillsborough
What you’ll pay for Unilock work in Hillsborough depends mostly on what’s underneath the pavers. A fresh driveway on a properly engineered base costs one thing; pulling up a heaved field, re-grading over expansive clay, and re-laying around protected root zones costs another. Here’s where our most common Hillsborough Unilock scopes land:
| Service | Typical Range in Hillsborough |
|---|---|
| Paver Driveway Installation | $7,000 – $18,000 |
| Paver Patio Installation | $3,500 – $11,000 |
| Driveway Replacement | $5,000 – $14,000 |
Our estimates include a full site walk, base assessment, and a written line-item quote so you know exactly what you’re paying for before any work starts. On a steep private lane off Brewer Drive near Unilock repair in Highlands-Baywood Park areas, our crew pulled up a heaved Brussels Block driveway where storm runoff had undermined the edge restraint over expansive clay. We called in an arborist to protect a redwood root zone, reset the engineered base to grade, and re-laid the field with fresh Unilock units and polymeric joint sand behind new edge restraints. The homeowner finally had a driveway that drained instead of caving. Call (833) 756-5936 for your free estimate.

FAQs – Unilock Construction in Hillsborough
No. We are an independent general contractor with deep hands-on experience installing and repairing Unilock pavers across Hillsborough. We don’t claim Unilock authorization or warranty endorsement. We do source genuine Unilock units and matching pavers where available to keep your existing field consistent, and we stand behind our base and installation work.
Yes, if the base, cross-slope, and edge restraint are engineered for it. Hillsborough’s sloped lots move a lot of water quickly during atmospheric-river storms. The failure point is usually not the paver surface; it’s the sub-base compaction, the joint sand, or the edge restraint. We design and re-lay driveways to move water off the field and into proper drainage, and we’ll tell you honestly if your existing base needs to be rebuilt rather than patched. Call (833) 756-5936 for an on-site assessment.
Most Hillsborough Unilock projects run from a few days for a repair or re-lay of a modest patio to two or three weeks for a full driveway replacement with base rebuild, arborist review, and drainage work. Tree-protection review and design approval can add time before work starts, but we handle that planning up front. We’ll give you a realistic sequence and schedule in your estimate.
We install and repair Brussels Block, Turfstone, Beacon Hill, and Town Hall. Brussels Block is the most common on Hillsborough’s older estate driveways. Beacon Hill and Town Hall show up on newer custom builds. If you have a different Unilock line, call us anyway and we’ll tell you straight whether we can match it or whether a border transition makes more sense.
Repair pricing spans a wide range because the real variable is what’s underneath. Small joint sand and paver reset work runs lower; a full re-base and re-lay after clay settlement or root intrusion runs higher, typically landing in the $3,500 to $14,000 range depending on area and base conditions. The estimate is free. Call (833) 756-5936 and we’ll walk the site with you.
