Unilock Construction in Las Lomas, CA | Spruce Contractors
We install, repair, and replace Unilock paver systems throughout Las Lomas, and the work here is shaped by something most contractors miss: this unincorporated Pajaro Valley community sits in Monterey County’s floodplain, which means every paver project has to answer to county grading and drainage rules, not Watsonville’s city code. That changes how we build bases, how we handle runoff, and which Unilock products actually hold up. If your driveway or patio is settling, stained, or holding water, call (877) 265-5771 for a free estimate from a crew that knows this specific ground.
Nate Calloway runs Spruce Contractors, and he’s spent enough years working San Mateo and Monterey County hillsides to know that the soil under a paver matters more than the paver itself. We’re an independent Unilock service provider, which means we work with the full product line and genuine OEM replacement parts, but we don’t answer to a manufacturer’s sales targets. We answer to you.
Key takeaways:
– Independent Unilock installer and repair specialist serving Las Lomas, CA
– County floodplain and agricultural buffer expertise baked into every quote
– Genuine Unilock OEM pavers plus climate-appropriate base and joint materials
– Free estimates, itemized pricing, and honest repair-vs-replace guidance

Why Las Lomas Residents Choose Us for Unilock Service
Most homeowners in Las Lomas don’t need a contractor who shows up with a catalog and a smile. They need someone who knows why a paver driveway on Hall Road fails differently than one in Capitola. We’ve been working Unilock systems in this valley long enough to recognize the patterns before we lift a single paver. Efflorescence from fog, settlement from clay, joint sand washing out during winter rains: these aren’t surprises to us. They’re Tuesday.
Nate’s background matters here. He grew up in Hillsborough watching older homes come down and new ones go up, then put in years on construction crews across San Mateo County before running his own projects. That means he’s seen what happens when a base isn’t compacted right, and he knows which materials survive the Bay’s wet winters. His daughter started at Hillsborough City School recently, so when he talks about building things that last, he’s not throwing around a slogan. He lives in the same zip code as the work he stands behind.
We specify Unilock because their modular paver systems, especially Brussels Block and Beacon Hill, give us a product we can install with confidence in this climate. But the product is only half the equation. The base, the drainage plan, and the joint material decide whether you’re redoing the job in five years or twenty. That’s where local knowledge earns its keep.

Common Unilock Construction Problems We Solve in Las Lomas
Paver failures in Las Lomas tend to follow a pattern, and we’ve seen most of them more than once:
– Efflorescence on Brussels Block pavers. The coastal fog and damp winters leave a white mineral haze on the surface. It looks like the paver is failing, but it’s actually salts migrating through the concrete. If you seal before treating it, the haze comes right back. We clean, treat, and seal in the right order.
– Paver settlement and heaving from inadequate base compaction. Las Lomas sits on clay-rich soil with high water tables near the Pajaro River floodplain. A base that works in sandy coastal soil won’t survive here. We see driveways drop two inches in a single winter when the base was never built for this ground.
– Joint sand erosion in Beacon Hill and Copthorne pavers. Poor drainage plus heavy winter rain equals joints that wash out, then weeds, then shifting pavers. The fix isn’t more sand. It’s fixing the drainage first, then using a polymeric sand that handles our damp climate.
– Color fading and surface degradation on older Town Hall pavers. These pavers sit in constant dampness with limited sun, and older installations lose their finish and start spalling. Sometimes sealing extends their life. Sometimes replacement is the honest answer.
– Water pooling near garages and foundations. We see this constantly on older Las Lomas properties where the grade has shifted over decades. It’s rarely just a paver problem. The water is telling you something about the slope. We listen.

Unilock Service in Las Lomas: What Local Conditions Mean for Your Equipment
Here’s the thing most Unilock pages won’t tell you: Las Lomas is unincorporated Monterey County, and your paver project doesn’t get to hide behind Watsonville’s rules. The county looks at grading, drainage, and flood-zone elevation because this land sits in the Pajaro River floodplain, right next to some of the most productive strawberry ground in the state. Agricultural buffers and runoff rules apply to residential parcels here in a way they simply don’t in incorporated cities. What that means for your Unilock driveway or patio is practical: the base has to be engineered to move water without sending it onto adjacent farmland or into the floodplain. A contractor who shows up with a standard paver quote and no drainage plan is guessing. On a recent job off Hall Road, we replaced a failing Brussels Block driveway that had settled and was holding water. The homeowner had persistent puddles near the garage, so we removed the old pavers, re-graded the base to improve drainage away from the house, and reinstalled with a compacted aggregate base and polymeric joint sand. County floodplain requirements met, and the driveway looks the way it should have from the start.

Unilock Models & Products We Service in Las Lomas
We work across the Unilock line most common in Pajaro Valley residential projects: Brussels Block, Beacon Hill, Copthorne, and Town Hall. Each has its own installation quirks and failure modes, and we stock or source the right materials for each. For repairs, we use genuine Unilock OEM replacement pavers whenever available. Color and size match matters, especially on a driveway where a mismatched paver stands out from the curb. Base materials and joint sands are where we’ll sometimes go aftermarket, because the right aggregate base and polymeric sand for Las Lomas’s clay and moisture aren’t always what the manufacturer ships by default. We tell you what we’re using and why before we start. Good work doesn’t need a lot of explaining, but you’ll get the explanation anyway because you’re paying for it.

FAQs – Unilock Construction in Las Lomas
Do Unilock pavers require special installation in Las Lomas due to county regulations?
Yes. Because Las Lomas is unincorporated Monterey County, paver projects can trigger county-level grading, drainage, and floodplain requirements that don’t apply in Watsonville or other incorporated cities. We design bases and drainage to meet those county standards from the first quote, so you don’t get hit with a surprise change order mid-project. Call (877) 265-5771 if you want to know how county rules apply to your specific parcel.
How does the coastal fog in Las Lomas affect Unilock pavers?
The fog and damp winters in Las Lomas accelerate efflorescence and moss growth on pavers, especially on Brussels Block. Frequent moisture pulls mineral salts to the surface, leaving a white haze that returns if the paver isn’t properly cleaned and sealed. The fix is a proper treatment sequence, not just pressure washing.
Can you repair my existing Unilock patio that has settled unevenly?
Yes, and this is one of the most common jobs we do in Las Lomas. We lift the affected area, re-grade and compact the base, address the drainage that caused the settlement, and reinstall the existing pavers if they’re in good shape. If matching pavers are needed, we source OEM replacements. Most patio repairs take one to two days.
What type of base is best for Unilock pavers in Las Lomas’s clay soils?
A compacted aggregate base with proper geotextile separation is what we use in Las Lomas. The clay-rich soil expands and contracts with moisture, and without a stable base and good drainage, pavers will shift within a season or two. We also adjust the base thickness based on whether your property sits in the floodplain or on higher ground.
Do you offer permeable paver options to help with drainage in the floodplain?
Yes. For properties in or near the Pajaro River floodplain, permeable paver systems can help manage runoff and meet county drainage requirements. We’ll assess your site and recommend whether permeable is the right call. Call (877) 265-5771 for a free site evaluation and an exact quote.
