Unilock Construction in Monte Sereno, CA | Spruce Contractors
We provide independent Unilock paver and retaining wall service across Monte Sereno, CA, from full driveway replacements to resetting failed joints on sloped hillside lots. The one thing that makes our Unilock work here different is that we plan every hardscape job around the city’s arborist report and tree-protection requirements before a single paver is delivered. Spruce Contractors is not manufacturer-affiliated or authorized by Unilock, and we’d rather tell a Monte Sereno homeowner their wall needs re-engineering than sell a rebuild it doesn’t need. Call (877) 265-5771 for a free estimate.
Why Monte Sereno Residents Choose Us for Unilock Service
Monte Sereno isn’t a standard tract-home market. Nearly every property sits on a large, heavily treed lot with some degree of slope, which changes how Unilock systems need to be installed and maintained. We’ve set Brussels Block driveways and Pasadena Block patios on these wooded hillsides long enough to know what happens when redwood roots lift a base course or winter rain saturates the joints and washes poly sand downhill. As a Monte Sereno General Contractor, Nate Calloway grew up in Hillsborough watching older homes get rebuilt and understands Bay Area hillside soil conditions intimately. You pick the look; we know the materials and the ground they’re going into.
We stock genuine Unilock units and compatible joint sand for color-matched repairs, and we source quality aftermarket base aggregate, geotextile, and drain components where they meet or exceed spec. You’re getting the same product line, not a mystery substitution. See our full Unilock sales & service page for the broader scope of what we cover.

Common Unilock Construction Problems We Solve in Monte Sereno
- Polymeric sand joint failure after winter rain. Monte Sereno sits in the Santa Cruz Mountains foothills, and when winter storms soak a sloped driveway, water migrates under the pavers and washes the joints out on the downhill side. We strip the failed sand, re-grade where needed, and re-joint with a Unilock-matched poly sand that sets properly in our wet-winter climate.
- Tree-root heave on paver walkways. Oak and redwood roots push up Pasadena Block walks and create a rocking trip edge. Common on Monte Sereno’s wooded lots. We lift the affected units, cut back the offending root, and re-set the base course so the surface stays flush.
- Beacon Hill retaining wall drainage clogging. Hillside silt fines blind the filter fabric behind the wall, hydrostatic pressure builds, and the wall face starts pushing out. We rebuild the drainage system with clean aggregate and new geotextile rather than just pushing the blocks back.
- Efflorescence and salt bloom on new Brussels Block driveways. Monte Sereno’s hot, dry summers can accelerate mineral migration through the pavers, especially where the base wasn’t compacted in lifts. We clean the bloom and address the base compaction that caused it.
- Depressions and wheel ruts in paver driveways. Heavier vehicles and poor subgrade prep on steep lots create low spots that pool water at the garage edge. We re-level the surface course or re-base the failed section depending on what the subgrade shows us.
Unilock Service in Monte Sereno: What Local Conditions Mean for Your Equipment
Monte Sereno is almost fully built out. There’s no greenfield, no easy expansion, and most lots are large, heavily treed parcels where the city requires an arborist report and tree-protection plan before grading permits are issued. That’s the step that surprises contractors who work mostly in Saratoga or need Unilock repair in Los Gatos. For Unilock owners it means your paver driveway or patio expansion has to be drawn around root protection zones, not just the design review packet. On a recent project off a quiet Monte Sereno lane, our crew replaced a cracked concrete apron with a Brussels Block paver driveway and re-graded drainage away from the garage. The arborist flagged a protected oak at the driveway edge, so we hand-dug the base course, kept the paver field outside the root zone, and set a hidden channel drain at the low side. The drive now sheds winter rain instead of pooling at the garage door. That’s the difference between a contractor who has pulled permits in Monte Sereno and one who hasn’t.

Unilock Models & Products We Service in Monte Sereno
We work with the Unilock lines that hold up best on sloped, tree-rooted lots. Brussels Block for driveways and motor courts where the tumbled, dimensional look hides minor surface wear. Pasadena Block for patios and walkways, where the finish stays consistent through rain cycles. Beacon Hill smooth-face wall block for retaining walls and grade transitions. Series pavers with Unilock permeable jointing for drainage-sensitive hardscape. Our stockroom keeps the common Monte Sereno colors and sizes on hand, and we also carry inventory for Cambrian Park Unilock service, so we’re not waiting on a truck from the distributor for most repairs. For discontinued or long-lead units, we source directly and tell you the timeline upfront.

FAQs – Unilock Construction in Monte Sereno
Yes, sometimes by $1,500 to $4,000. An arborist report and tree-protection plan are required on most treed Monte Sereno lots before grading, and hand-digging a base course around protected roots takes more labor than running a skid steer through an open yard. If you have a protected oak at the driveway edge, expect hand excavation near the drip line. Call (877) 265-5771 and we’ll walk your lot before you commit to anything.
Brussels Block is the best choice for a sloped driveway in Monte Sereno. Its tumbled, dimensional edges give the surface more interlock under wheel load than a smooth-face paver, which matters when a car is turning on a grade. We recommend a permeable or channel-drain design on any slope above 3% to keep winter rain from pooling at the garage.
Generally yes for retaining walls over 3 feet and for any hardscape that involves grading, drainage changes, or tree protection. Patios at grade may not need a building permit, but Monte Sereno’s design review process can still flag them. We pull permits ourselves for walls and driveways so you’re not stuck navigating City Hall on a hillside parcel.
Almost always because water is migrating under the pavers on the downhill side, which means the base course on the low side isn’t draining. Monte Sereno’s winter rain saturates the joints, and if there’s no positive drainage away from the driveway edge, the sand washes out with every storm. We fix this by re-grading the base and installing a hidden channel drain at the low elevation before re-jointing. Call (877) 265-5771 for a drainage assessment.
Sometimes. If your existing concrete apron has failed but the subgrade underneath is sound, we can remove the concrete and set Unilock pavers on a proper base without re-contouring the entire lot. If the subgrade has washed or settled, which happens often on sloped Monte Sereno hillsides, a partial re-grade is necessary to keep the new paver field from failing in two seasons. We’ll tell you which case you’re in before we quote a dollar figure.
