Unilock Construction in Monte Sereno, CA | Viceroy Construction
We provide independent Unilock construction and repair across Monte Sereno, from paver driveways and patios to retaining walls and estate hardscape. What makes our work here different is simple: we plan every Unilock project against Monte Sereno’s strict lot-coverage and impervious-surface caps before a single paver goes down. That means your driveway, patio, or pool deck not only looks right but actually passes the town’s planning scrutiny. Call (877) 358-6557 for a free estimate.
Why Monte Sereno Residents Choose Us for Unilock Service
We’ve built enough Unilock hardscape in Monte Sereno to know exactly how these pavers behave on the town’s sloped, 1/3-acre-and-up estate lots. Neil Drummond grew up in the Saratoga foothills and trained in the building trades program at West Valley College, where framing, concrete, and structural coursework taught him what holds up and what doesn’t. That background matters when you’re laying Brussels Block on a 12% grade or engineering drainage behind a Pisa retaining wall. We use genuine Unilock pavers and matching wall components, paired with quality polymeric joint sand and proper edge restraint. We don’t substitute cheap aftermarket units to shave a bid. The details you don’t see are the ones that matter most.
We also know the town itself. Monte Sereno has no commercial zoning, almost entirely large-lot single-family homes, and an approval process that neighboring Los Gatos and Saratoga don’t apply the same way. That local fluency shows up in how we scope the work. We’re not manufacturer-affiliated or authorized by Unilock. We’re an independent installer whose credibility is built on jobs that hold up through wildfire season and winter runoff. For more on our Unilock sales & service capabilities, see the brand page.

Common Unilock Construction Problems We Solve in Monte Sereno
- Joint sand washout and edge migration on sloped driveways. Winter rains hit Monte Sereno hillside lots hard, and when runoff isn’t managed, it strips joint sand and pushes pavers outward at the edges. We see this constantly on long, steep drives where the original install skimped on edge restraint. The fix is re-sanding with polymeric sand and installing proper restraint, not just sweeping more sand in.
- Efflorescence and surface staining from roof and site drainage. Lighter Unilock lines like Beacon Hill show white mineral deposits when runoff from roofs and site drains isn’t directed away from the paver surface. On Monte Sereno estate lots with big roof planes, this is a recurring issue. We address the drainage path first, then clean and re-seal.
- Base settlement and rutting on under-compacted sub-bases. We’ve pulled apart driveways where the original base was never compacted to spec, and years of vehicle loads on a steep grade created ruts you could feel through the steering wheel. Cambridge and Brussels Block both show this failure mode. The repair means pulling the pavers, re-grading, re-compacting, and re-laying.
- Retaining wall bowing and cap displacement from saturated hillside soils. Pisa walls built without engineered drainage behind them bow outward after a few wet winters. The weight of saturated soil pushing against the wall is enormous. We rebuild the wall with proper gravel backfill and drainage pipe so the water has somewhere to go.
- Driveway apron heaving at the low corner of the slope. This one’s specific to Monte Sereno’s topography. When water pools at the bottom of a sloped drive, it undermines the base and the apron lifts or settles unevenly. We fix it by re-grading the sub-base to shed water away from the garage.
Unilock Service in Monte Sereno: What Local Conditions Mean for Your Hardscape
Here’s the thing most Monte Sereno General Contractor competitors won’t tell you about Monte Sereno: this is one of the smallest, wealthiest incorporated cities in California, under 3 square miles, with no commercial zoning and strict lot-coverage and setback limits. That’s not a fun fact. It’s a construction constraint. Any new Unilock driveway, patio, or pool deck has to be sized against the property’s existing coverage, and on many of these estate lots, adding a paver surface can push you right up against the impervious-surface cap. Sometimes the answer is a permeable Unilock system that lets water pass through instead of running off. Sometimes it means reconfiguring the layout so the new hardscape replaces old concrete instead of adding to total coverage. Either way, the planning has to happen before the pavers arrive, not after the town flags it. On an estate lot off Vineland Avenue we replaced a heaved, sand-starved paver apron where winter runoff had undermined the base at the low corner of a sloped drive. We pulled the Brussels Block, re-graded and re-compacted the sub-base to restore drainage away from the garage, re-laid the units in the original pattern, and locked them with polymeric sand and new edge restraint. The drive now sheds stormwater instead of puddling against the door. That’s what Monte Sereno work actually looks like.
Unilock Models & Products We Service in Monte Sereno
We install and repair the full range of Unilock hardscape products commonly used in Monte Sereno: Brussels Block for estate driveways and aprons where the classic tumbled edge fits the mid-century architecture, Beacon Hill for patios and pool decks where a cleaner, more contemporary surface is wanted, Cambridge for both driveways and walkways where a modular three-piece pattern works well, and the Pisa retaining wall system for terracing and hillside retention. When existing hardscape is sound, we re-level and re-sand rather than tear out. Replacement is reserved for failed base or cracked units. We stock common Unilock pavers and matching wall components locally for faster Unilock in Campbell and Monte Sereno turnaround, and we order exact color and dimensional matches for larger jobs.

AfterUnilock Service Pricing in Monte Sereno
Unilock work in Monte Sereno runs on the same project costs as the surrounding Cambrian Park Unilock service area market, though slope and drainage conditions can push a job toward the higher end of a range. A paver driveway on a steep lot with significant re-grading work will cost more than a flat patio over stable ground. Our estimates are free, in writing, and line-itemed so you see exactly where the money goes. Here’s what to expect:
| Project | Typical Price Range |
|---|---|
| Paver Driveway Installation | $7,000 – $18,000 |
| Paver Patio Installation | $3,500 – $11,000 |
| Driveway Replacement | $5,000 – $14,000 |
| Home Addition | $45,000 – $130,000 |

FAQs – Unilock Construction in Monte Sereno
Yes, in most cases a new paver surface counts as impervious coverage, and Monte Sereno enforces strict lot-coverage caps. We review your property’s existing coverage during the estimate and, where needed, recommend a permeable Unilock system or a layout that replaces existing concrete instead of adding new coverage. Call (877) 358-6557 for a site assessment before you plan around a specific paver size.
Absolutely. Slopes over 5% need deeper excavation, geotextile fabric, and properly compacted aggregate base in lifts, plus drainage planning so water doesn’t undermine the pavers. We see more base failures on steep Monte Sereno lots than anywhere else in the South Bay, and almost all of it traces back to under-compaction or skipped drainage work on the original install.
Unilock concrete pavers are non-combustible and perform well in wildland-urban interface zones, but the real issue is keeping hardscape integrated with defensible-space clearing and drainage. Gravel, decomposed granite, and paver surfaces all hold up to heat far better than wood decking, which is partly why so many Monte Sereno homeowners are replacing combustible surfaces near the house.
Usually yes. We use genuine Unilock pavers so color and dimensional tolerances stay consistent, and we can order from the same product line and batch when needed. Weathering can make an exact match harder on older installations, but blending new and existing Brussels Block or Cambridge units is something we do regularly on Monte Sereno estate properties.
No. Efflorescence is a white mineral deposit that rises to the surface with moisture and can be cleaned with the right paver-safe products. Fading is gradual and doesn’t compromise structural integrity. If the pavers are sound, we re-level, re-sand, and clean rather than tear out. Replacement is for cracked units or failed base.
