Unilock Construction in Los Altos Hills, CA | Milpitas Construction
Milpitas Construction provides independent Unilock paver, wall, and fire feature installation and repair throughout Los Altos Hills. We have installed Unilock Brussels Block, Beacon Hill, Umbriano, and Treo across this town’s steep, wooded lots for more than a decade. The one thing that makes our Unilock work different here: every project on a private road or hillside triggers a drainage review that most neighboring towns never require, and we build bases and edges specifically to pass it. Call (877) 752-4194 for a fix or a full paver driveway plan.
Why Los Altos Hills Residents Choose Us for Unilock Service
Ken Stafford runs Milpitas Construction, and he has spent two-plus decades building in Bay Area conditions that punish shortcuts. We know Unilock’s product line from real installation reps and real repair calls, not from a catalog. We are independent: not authorized, sponsored, or endorsed by Unilock. We choose their systems because they perform on Los Altos Hills terrain.
When a Unilock driveway on a private road settles or a Treo patio loses its edge, we diagnose the base and drainage first, not just the visible paver. That matters here. Los Altos Hills lots run one acre or more, often with unimproved shoulders, oak roots, and downslope neighbors whose wells and septic systems the town requires you to protect. We pull permits, we submit the drainage exhibits, and we schedule work around private-road flagging without making your project the neighbor’s drainage problem.
We also carry OEM-compatible Unilock pavers and edge restraints for repair and extension work. That means a Brussels Block apron or Umbriano path can be matched without waiting on a special order. For base and drainage components, we spec quality aftermarket geogrid and perforated pipe because Unilock does not manufacture those layers. That is the right call. The paver is only as good as what sits under it.

Common Unilock Construction Problems We Solve in Los Altos Hills
- Efflorescence on Brussels Block driveways. White salt deposits form when winter runoff from unimproved private-road shoulders sheets across the pavers and never fully drains. This is common along narrow roads off Stonebrook, where the shoulder drops right onto the driveway field. We re-route runoff and clean the surface so the salt stops bleeding through.
- Base settlement and paver heave on sloped driveways. Hillside drainage routed under the pavers instead of away from them wrecks the base layer after El Niño rains. On one-acre lots without curb and gutter, that water has nowhere to go but down. We re-grade, add infiltration, and re-lay the field tight.
- Joint sand loss and edge restraint failure on Umbriano patios. Protected oak roots push up from below and the bedding layer shifts. The pavers themselves stay intact but the field turns uneven within a season or two. We reset the edge and stabilize the base without damaging the root zone the town protects.
- Surface spalling on west-facing Beacon Hill walls. Full afternoon sun plus wildfire ember wash wears older wall units hard on exposed slopes. The face flakes and the color fades. We replace spalled units with OEM Beacon Hill and adjust the cap detail so it sheds heat better.
- Driveway failure at the garage lip. Runoff channels off unimproved shoulders and ponds right where the apron meets the slab. We fixed a Brussels Block apron on a steep private drive off Stonebrook Court that had settled two inches at the lip. The re-grade and new infiltration trench passed the town’s hillside review and the fire-hardening defensible-space check.
Unilock Service in Los Altos Hills: What Local Conditions Mean for Your Equipment
Los Altos Hills is a semi-rural town of one-acre-plus lots and private roads, and nearly every construction project triggers the town’s hillside and drainage review. That review requires a grading plan showing downslope impacts on neighboring wells and septic systems. It is not a formality. It dictates where you can place a dry well or infiltration trench, and that decision directly changes the Unilock paver base design. In Palo Alto or Unilock repair in Los Altos, a paver driveway is often a straightforward base-and-sand job. Here it is an engineered surface. If you skip the exhibit or guess the drainage, the town rejects the permit or your neighbor’s well takes the runoff. This is why our Unilock driveways and patios in Los Altos Hills start with the water, not the paver. The paver is the top layer. The drainage is the project.
Add WUI fire-hardening requirements and the stakes rise again. Pavers near the structure have to support defensible-space access without shedding ember-catching debris. We account for that in every driveway and patio plan, including material selection and edge detail.
Unilock Models & Products We Service in Los Altos Hills
We install and repair the Unilock lines that hold up on Los Altos Hills slopes: Brussels Block for driveways and aprons, Beacon Hill for retaining and seat walls, Umbriano for patios and pool decks with a smooth, contemporary surface, and Treo for fire pit surrounds and accent paving. For repairs and extensions we use Unilock OEM pavers, wall units, and edge restraints so the color and bond match the existing field. We stock common Brussels Block and Umbriano units locally for faster Los Altos Hills turnaround, and we order Treo and Beacon Hill units in quickly through our Mountain View Unilock service. For everything below the paver, we use aftermarket geogrid and perforated pipe because Unilock does not manufacture them, and the base in this town matters more than in most places.

AfterUnilock Service Pricing in Los Altos Hills
Paver work in Los Altos Hills costs more per square foot than flat-lot work in San Jose, and the reason is local: hillside access, drainage exhibits, and private-road logistics. Here are our current market ranges for the work we do most often:
| Service | Typical Range |
|---|---|
| Paver Driveway Installation | $7,000 – $18,000 |
| Paver Patio Installation | $3,500 – $11,000 |
| Driveway Replacement | $5,000 – $14,000 |
What drives the number: slope grading, drainage exhibit preparation, existing base condition, and whether the site needs an infiltration trench approved under hillside review. If more than 20 percent of a driveway field is settled or spalled, we recommend a full re-lay over spot patching. Patching a failed base on a sloped lot just moves the failure downhill. Call (877) 752-4194 for a free estimate that includes the drainage plan.

FAQs – Unilock Construction in Los Altos Hills
Yes. Nearly every paver driveway on a private road in Los Altos Hills triggers the town’s hillside and drainage review, which requires a grading exhibit showing downslope impacts on neighboring wells and septic systems. That exhibit often dictates where we can place a dry well or infiltration trench. Milpitas Construction prepares the exhibit as part of the permit package. Call (877) 752-4194 to discuss your site before you file.
Yes, properly installed Unilock pavers perform well within WUI defensible-space standards. They are non-combustible and do not trap ember-catching debris the way bark or wood decking can. The edge detail and base grading still need to support fire-access and runoff control. We design for that on every Los Altos Hills install.
Efflorescence on Brussels Block comes from water carrying salts through the paver and depositing them on the surface. In Los Altos Hills, the common trigger is winter runoff off an unimproved private-road shoulder that sheets across the driveway and never fully drains. Cleaning the surface helps for a while, but fixing it for good means re-routing the runoff and correcting the base drainage. That is standard work for us here.
No. Sloped patio sites in Los Altos Hills require engineering for any retaining component, and the town’s review looks at downslope drainage as part of the same package. Skipping the engineering usually fails inspection and can push water onto a neighbor’s septic area. We do the engineering with the paver plan, not after it.
Private roads in Los Altos Hills are often narrow with unimproved shoulders, so we use small equipment and schedule flaggers for paver and base material deliveries. We coordinate with the town and your neighbors on delivery windows and staging, because a paver truck cannot park the way it does on a city street. This adds a logistics step but keeps the road open.
