Unilock Construction in Los Gatos, CA | Spruce Contractors
Spruce Contractors installs and repairs Unilock paver driveways, patios, and retaining walls across Los Gatos, from the 95030 flats to the Lexington Hills Unilock service areas off 95033. Our work here carries a different set of demands than what flat-lot paver companies handle daily: tree ordinances around native oaks, hillside drainage, and base compaction over expansive clay. We are an independent contractor, not an authorized Unilock dealer, and we specify Unilock systems by name for one reason: we know how these units perform on graded lots, and we know what makes them fail. Call (877) 265-5771 for a free estimate.
Why Los Gatos Residents Choose Us for Unilock Service
Nate Calloway runs our crews with a simple rule: the base matters more than the paver. That’s doubly true in Los Gatos, where a driveway cut into a hillside behaves nothing like one poured on a level Santa Clara Valley lot. We’ve spent enough seasons in these foothills to know which soil pockets swell in winter and which slope grades start pulling joint sand after two wet years. We build the Unilock system to survive those conditions, not just to look sharp for a photo. Our Unilock sales & service approach means we stock the manufacturer’s edge restraints, bedding materials, and polymeric sand rather than mixing in substitutes that show up as color drift at the joints within a season.
Some contractors treat pavers as decorative concrete slabs. We treat them as a layered system: excavated subgrade, geotextile where the clay demands it, compacted aggregate in lifts, then the Unilock units on a screeded bed. Skip one step and the whole surface telegraphs it within two winters. We specify the layers properly the first time because re-excavating a failed driveway off a mountain road costs far more than building it right.

Common Unilock Construction Problems We Solve in Los Gatos
- Edge spalling and surface scaling on tumbled pavers: Brussels Block and similar tumbled units absorb more moisture than dense concrete pavers. When winter rain saturates the base and the lot’s hillside drainage was never addressed, the trapped water expands and contracts through the units, flaking the surface edges. We correct the drainage first, then re-set the damaged units. If you see chipped edges spreading across an older Los Gatos patio, the paver is rarely the root cause.
- Lateral creep and joint sand loss on sloped driveways: Driveway aprons cut into a Los Gatos hillside put constant downhill pressure on the paver layer. Without an oversized aggregate base and proper edge restraint, the whole field creeps downhill a fraction of an inch each wet season. You’ll see widening gaps at the top joints and sand washing out at the bottom. We rebuild these with deeper base sections and Unilock’s matching restraint systems, not aftermarket edging.
- Paver settlement over expansive soils: The clay-rich soils common on Los Gatos slopes expand when wet and shrink when dry. Pavers laid directly over an under-prepared clay subgrade will settle unevenly within a few years. We see dips and birdbaths forming in older patios around downtown Los Gatos and the 95030 hills. The fix is over-excavation, geotextile separation, and re-compaction in lifts before a single paver goes back down.
- Retaining wall face bulging on Pisa2 systems: A Pisa2 wall is only as strong as the geogrid and drainage stone behind it. We regularly find walls in Los Gatos that were built as gravity walls without any reinforcement, then loaded with a full winter’s runoff from the slope above. The face starts to migrate forward, blocks separate, and the wall looks pregnant. Repair usually means rebuilding the affected section with proper drainage and grid, not stacking the blocks back and hoping.
- Efflorescence blooming after the first wet season: That whitish haze on newer Unilock pavers in Los Gatos isn’t a defect. It’s mineral salts migrating to the surface as moisture moves through the base and the units. It appears more aggressively here because our wet winters drive more water through the paver profile than drier valley climates. Proper base drainage and correct joint sand reduce it. Sealing too early locks moisture in and makes it worse. We tell homeowners what they’re actually seeing before recommending a fix.
Unilock Service in Los Gatos: What Local Conditions Mean for Your Equipment
Los Gatos sits at the base of the Santa Cruz Mountains, and that single fact changes Unilock construction in ways a flat-lot paver page never addresses. The Town of Los Gatos enforces hillside and tree-protection ordinances written specifically for the wildland-urban interface, and protected native oaks often sit exactly where a paver driveway or patio would logically go. You cannot cut the roots. You cannot remove the tree. So we design Unilock installations around root zones, using root-preserving base details, bridging where necessary, and grading so runoff moves away from the trunk rather than pooling at the base. That means excavating shallower in some areas and deeper in others, adding geotextile to separate root-affected soil from the aggregate, and choosing unit patterns that tolerate the subtle ground movement living roots create. Up in the 95033 mountain ZIPs, we add slope-stability and fire-safe grading considerations, because the Town’s hillside review process won’t sign off on a paver project that increases erosion or blocks emergency access. A paver driveway isn’t just a surface here; it’s part of the site’s drainage and defensible-space system. We design it that way from the first sketch.
Unilock Models & Products We Service in Los Gatos
We work with the full Unilock line: Brussels Block for that tumbled, old-world profile, Beacon Hill Flagstone for larger-format patios, Pisa2 for modular retaining walls, and the Copthorne and Town Hall series for clean-lined driveways. We use Unilock-manufactured units and their matching edge restraints and polymeric sand, not aftermarket lookalikes. Color and dimensional tolerances break down fast at the joints when you mix suppliers, and the mismatch reads like a patch job within one season. For Los Gatos turnaround, we keep common Unilock units and matching restraint systems accessible through our local supplier network, so mid-project repairs and phased installations don’t stall while a pallet ships from the Midwest. When a repair calls for a specific discontinued color, we’ll track down remaining stock before substituting anything that won’t match.

AfterUnilock Service Pricing in Los Gatos
Los Gatos paver work prices differently than valley floor work because the site conditions drive the prep. A flat, well-drained lot with clean soil costs less to prep than a hillside with expansive clay and a protected oak in the middle. Here’s what we quote in this market:
| Unilock Service | Typical Range |
|---|---|
| Paver Driveway Installation | $7,000 – $18,000 |
| Paver Patio Installation | $3,500 – $11,000 |
| Driveway Replacement | $5,000 – $14,000 |
| Driveway Sealing | $250 – $700 |
The range reflects site prep depth, slope, access, and whether we’re pulling a failed base or starting clean. A free estimate from us includes walking the site, checking drainage patterns, and identifying whether protected trees or hillside review will shape the design. Call (877) 265-5771 to schedule yours.

FAQs – Unilock Construction in Los Gatos
Yes, and it’s work we do regularly in Los Gatos. We design root-zone-preserving base details that keep the paver system clear of major roots while giving the surface enough support to prevent settling. The key is grading runoff away from the tree rather than toward it, which keeps the root crown dry and satisfies the Town’s tree protection requirements. We will not cut roots to simplify a layout; we work around them. Call (877) 265-5771 if you have a protected oak shaping your project.
The answer depends on what’s behind the face of the wall. If the blocks themselves are intact and the failure is from missing geogrid, undersized drainage stone, or a footing that never keyed into stable soil, we can often rebuild the affected section properly and reuse the blocks. If the units are cracked or spalled beyond re-use, replacement is the honest call. On a steep lot off the 95033 mountain ZIPs, we rebuilt a Brussels Block driveway that had crept downhill after two wet winters, pulling the failed base, adding geotextile over the expansive clay, and re-compacting in lifts before re-setting the pavers. The Pisa2 wall below it finally got the drainage stone and geogrid it never had the first time. Call (877) 265-5771 and we’ll tell you which path your wall actually needs.
Yes. Los Gatos winters drive water through the paver profile differently than a dry summer, and any drainage deficiencies in the base show up as settling, joint sand loss, or surface scaling by spring. Patios on expansive clay are especially vulnerable if no geotextile separation was used at the original install. We build the base to handle full winter saturation, not just summer traffic. For an exact assessment of your patio, call (877) 265-5771.
We are an independent contractor. We are not authorized, sponsored, or endorsed by Unilock, and we don’t claim to be. We specify and install their paver and wall systems because we know the bedding and compaction requirements well, and we’ve seen how the units perform on graded Los Gatos lots over multiple wet seasons. That field experience is what we bring to your project, not a manufacturer badge.
Paver driveway installation runs $7,000 to $18,000, paver patios $3,500 to $11,000, and a full driveway replacement $5,000 to $14,000, depending on slope, soil, and access. Hillside prep and oak-root accommodations push toward the higher end. Call (877) 265-5771 for a free estimate that reflects your actual site.
