Unilock Construction in Castroville, CA | Milpitas Construction
We provide independent Unilock paver and retaining wall installation and repair across Castroville, CA.

We’re a full-scope general contractor with access to 50+ brand-name product lines, and Unilock is one we know down to the base material — learn more about our General Contractor in Castroville.
Why Castroville Residents Choose Us for Unilock Service
Ken Stafford, our owner, has spent two-plus decades working in and around the Bay Area’s coastal valleys, and he’s seen what damp air does to a poorly prepped paver base. We don’t sell Unilock; we install and repair it as an independent contractor. That independence matters in Castroville because we call out a shallow base or a grading problem before it becomes a sunken driveway. Our crews follow Unilock’s published installation specs, and we pair genuine Unilock units with base and joint-sand materials suited to damp coastal soils. Unilock sales & service through Milpitas Construction means one accountable team from the first excavation to the final compaction, not a dealer script and a subcontractor who never saw the original estimate.

Common Unilock Construction Problems We Solve in Castroville
- Efflorescence on Brussels Block and Hollandstone pavers. Castroville’s fog keeps paver surfaces damp and slows evaporation between wet and dry cycles. That white mineral bloom isn’t a product defect; it’s moisture moving through the paver pulling salts to the surface. We remove it and adjust drainage so it doesn’t keep coming back.
- Paver edge slumping and joint sand loss on driveways. Harvest season brings heavy trucks and equipment cutting across residential frontages. When the base is only a few inches deep over native soil, edges spread and joints empty out. We rebuild the base, not just the surface.
- Moss and algae in shaded paver joints. Marine air that never fully burns off means patios on the north side of older Castroville homes stay wet. Joint sand washes out, moss moves in, and the surface gets slick. We reset the field and re-sand with an angular, stabilized product that resists washout.
- Pisa2 retaining wall settlement. Field-edge lots in Castroville drain poorly, and saturated soil through the fog season pushes on wall sections. Wall caps shift, courses tilt. We fix the drainage behind the wall first, then re-level the wall itself.
- Color matching on weathered Unilock units. A 15-year-old Brussels Block driveway doesn’t match a new pallet. The sun and marine air have faded the original. Blending new units into a weathered field is often the honest answer over a tear-out, and we’ll tell you when it isn’t.
Unilock Service in Castroville: What Local Conditions Mean for Your Pavers
Here’s what changes in Castroville compared to a subdivision in Salinas or Marina. Much of the older downtown housing was built for seasonal farm labor, so frontages are narrow and often share a single unpaved or partly paved access strip with a neighboring lot. That means Unilock driveway and patio work here usually starts with resolving shared access, drainage, and property-line questions before a single paver comes off the truck. You can’t just widen a driveway or re-grade a patio when the water from your neighbor’s lot runs across your paver field. We’ve worked on older single-story homes off the downtown grid where the only access for equipment is a shared strip barely wide enough for a wheelbarrow. Sequencing the job around that reality is half the work. On one of those homes, our crew pulled up a sunken Brussels Block driveway that had rocked loose for years under harvest-season truck traffic and found a base only a few inches deep over damp native soil. We re-graded and compacted a proper aggregate base with drainage away from the shared access strip, then reset the salvageable Unilock units and blended in new ones for the damaged runs. The result is a driveway that sheds fog-season moisture instead of holding it in the joints. That’s the difference between a paver job that lasts and one that looks good for two winters.
Unilock Models & Products We Service in Castroville
We install and repair the full range of Unilock products you’ll find in Castroville yards: Brussels Block, Hollandstone, Beacon Hill, and the Pisa2 retaining wall system. When a repair calls for matching units, we source genuine Unilock pavers and pair them with base and joint-sand materials appropriate to damp coastal soils. Discontinued colors happen, and matching a decades-old faded field isn’t always possible. When it isn’t, we’ll say so and offer the most sensible path: blending new units, resetting an existing field on a corrected base, or replacing a section with a deliberate contrast. We don’t push full tear-outs when a repair will hold.

FAQs – Unilock Construction in Castroville
We can often blend new Brussels Block units into a weathered field, but an exact match on a decades-old surface is rarely possible. The coastal sun and marine air change the paver color over time. We’ll show you samples against your existing field and recommend either a blend or a deliberate contrast section. Call (877) 752-4194 and we’ll bring samples to your home.
Castroville’s persistent coastal fog means shaded paver surfaces may stay damp for weeks. Moss and algae move into joints when the sand washes out and the surface never fully dries. The fix is usually re-sanding with a stabilized product and improving surface drainage, not just pressure washing. Call (877) 752-4194 for a site evaluation and a re-sanding quote.
Yes. Fog-season moisture saturates the soil behind a Pisa2 wall, especially on field-edge lots with poor drainage. That saturation adds lateral pressure and causes settlement and cap shifting. We address the drainage behind the wall first, then re-level the wall. A wall that holds through Castroville’s damp winters needs proper drainage and a solid base. Call (877) 752-4194 to have your wall inspected.
We resolve shared access, drainage, and property-line questions before any excavation. That means talking with your neighbor or their property manager about access during the job, confirming where the property line sits, and making sure the finished paver field doesn’t push water onto the adjacent lot. This is standard practice for Castroville’s older downtown housing. Call (877) 752-4194 and we’ll walk the site with you first.
If the base is intact and the pavers are sound, resetting and re-sanding is often the better value. If the base has failed, you’ll fight the same problems every few years until it’s rebuilt. We’ll pull a few units and check the base before recommending anything. Call (877) 752-4194 for an honest assessment and a written quote.
