Unilock Construction in Saratoga, CA | Toolbox Contractors
We provide independent Unilock paver installation and rebuilding across Saratoga, CA and nearby communities including Unilock service in Los Gatos, from Brussels Block driveways to U-Cara retaining walls on steep hillside lots. The single biggest difference in our work here: we plan every Unilock assembly around Saratoga’s septic systems, well locations, winter storm runoff, and wildfire defensible-space rules before we ever excavate. Most paver quotes from flatland crews skip those steps and the driveway pays for it later. Call (855) 382-3257 for a free estimate, or keep reading to understand what your hillside property actually needs.
We carry genuine Unilock units and matching edge restraints, and we rebuild full bases when the existing one has failed. We are not affiliated with, sponsored by, or authorized by Unilock. We’re a licensed general contractor that installs and repairs their systems because they hold up in Saratoga conditions when the base is done right.
Why Saratoga Residents Choose Us for Unilock Service
Norm Castellano runs Toolbox Contractors with a simple approach: he’s the guy you call when a previous contractor left a mess and the real work hasn’t started yet. He grew up around half-finished houses in Muscoy, learned construction fundamentals at San Bernardino Valley College, and spent nearly two decades framing, roofing, and rebuilding kitchens across the Inland Empire before taking on hardscape work in Saratoga’s hills. His crew has seen what happens when pavers get laid over bad base, and they know how to fix it properly.
Saratoga homeowners call us because we treat a Unilock driveway as a structural system, not a cosmetic layer. We hand-dig to locate old septic leach lines and private wells before any base excavation. We re-establish positive slope away from garages and foundations. We use OEM Unilock units for color-matched field patches, and spec-equivalent polymeric sand and base aggregate where it makes structural sense. You get one contractor who owns the entire job from the first shovel cut to the final sweep of sand.

Common Unilock Construction Problems We Solve in Saratoga
- Efflorescence and salt bloom on Brussels Block and Copthorne. Saratoga’s winter atmospheric-river storms push water through hillside irrigation zones and into paver joints, keeping them saturated for weeks. That mineral-rich water rises through the units and leaves white salt deposits on the surface. We clean the bloom, correct the drainage path feeding it, and reseal the field.
- Polymeric sand washout on sloped driveways off Highway 9 and Pierce Road. When sheet flow concentrates during heavy storms, water moves fast across an angled paver field and scours the joints. We address it by re-grading the surface flow, replacing the sand with a well-compacted spec-equivalent product, and installing edge restraint that actually holds.
- Edge restraint failure and paver migration over old concrete. Many 1950s and 1960s Saratoga ranch homes have unpermitted concrete aprons or walkways under what appears to be a paver driveway. The base underneath has no gravel structure, so the edges creep outward and wheel loads crack the joints. We pull the field, haul out the failed flatwork, and rebuild from soil up.
- Unit spalling and color loss on south-facing patios. Saratoga’s hot, dry summers bake exposed pavers for months. When sprinkler overspray hits a baked paver surface repeatedly, the thermal shock and mineral deposition wear through the surface layer. We replace spalled units, adjust irrigation throw, and reseal the whole field.
- Costly discovery of septic and well lines mid-project. On hillside estate lots, original 1960s leach fields and well casings often sit right under what looks like an empty area for a patio expansion. A contractor who excavates blind can puncture a leach line or crack a casing. We locate everything before the machine starts, which saves Saratoga homeowners a five-figure repair they didn’t budget for.
Unilock Service in Saratoga: What Local Conditions Mean for Your Equipment
Here’s the thing most paver quotes don’t mention: on many Saratoga hillside properties, the original 1960s septic systems and private wells are still in use, and they sit directly under the flat pads that look perfect for a paver patio or a widened driveway. Any excavation over a leach field or well easement triggers a Santa Clara County percolation test and well-yield certification, and trenching near a leach line without knowing its exact layout can collapse the field entirely. We hand-dig test pits and verify utility locations before any base excavation happens off Pierce Road or anywhere else in the foothills. That step takes a few extra hours on the front end, and it’s the difference between a driveway that lasts decades and one that gets torn up by the county six months after it’s finished. No flatland tract crew from San Jose thinks about this until the inspector is standing on the site. We plan for it from the first walk-through.
The drainage side matters too. Saratoga sits at the base of the Santa Cruz Mountains with hot, dry summers and sudden winter storm cycles. A paver driveway on a 12% grade off Highway 9 moves water fast, and the base has to be built to shed it without blowing out the joints. We build positive slope into the assembly itself and make sure the storm runoff has a clear path to a legal discharge point, not into the neighbor’s hillside or your own foundation.
Unilock Models & Products We Service in Saratoga
We install and rebuild the Unilock lines most common on Saratoga properties: Brussels Block for driveways and entry courts, Beacon Hill Flagstone for patios and pool decks, Copthorne for a more formal estate look, and the U-Cara retaining wall system for terracing sloped lots and holding back hillside cuts. For repairs, we use genuine Unilock units when the existing field can be color-matched and the base under it is structurally sound. When the base has failed, we won’t simply drop new pavers on top of it. We rebuild the aggregate structure from the subgrade, set new edge restraints, and then lay the field. It costs more up front than a patch job, and it’s the only repair that actually lasts on a Saratoga hillside. Our Unilock sales & service work covers new installs, full rebuilds, and field repairs across the 95070 and 95071 zip codes.

AfterUnilock Service Pricing in Saratoga
Paver work in Saratoga runs higher than flatland pricing because the site conditions demand more prep: slope correction, septic and well verification, drainage re-routing, and wildfire-adjacent material choices all add labor hours before the first paver is set. Here’s what you should expect in this market:
| Service | Typical Range in Saratoga |
|---|---|
| Paver Driveway Installation | $7,000 – $18,000 |
| Paver Patio Installation | $3,500 – $11,000 |
| Driveway Replacement | $5,000 – $14,000 |
| Driveway Sealing | $250 – $700 |
What drives the price is what’s under the pavers. A driveway with a failed concrete apron underneath costs more because we haul out the old flatwork and rebuild from clean subgrade. A patio with septic lines running through it costs more because we hand-dig and adapt the design around the field. Every estimate we write is line-item, so you see exactly where the money goes. Call (855) 382-3257 to schedule yours. There’s no charge for the estimate and no obligation to move forward.

FAQs – Unilock Construction in Saratoga
Can Unilock pavers be installed on a Saratoga hillside driveway without triggering county grading review?
Yes, if the project stays under the county’s grading threshold and doesn’t move more than the permitted cubic yards of material. But if your driveway is on a steep lot and the base has failed, re-grading that slope often triggers review anyway. We check your property against Santa Clara County’s current grading and geotechnical requirements before we quote, just as we do for Unilock repair in Cupertino, so you know what’s coming. Call (855) 382-3257 and we’ll walk you through what applies to your specific lot.
Why does the polymeric sand keep washing out of my Unilock joints every winter?
Because water is moving across your paver field too fast, and the sand is the first thing it takes with it. On Saratoga hillside driveways and patios off winding roads, concentrated sheet flow during atmospheric-river storms scours joints unless the assembly includes proper edge restraint, a compacted base, and surface drainage that directs water off the field. We fix the drainage first, then reset the sand. Call (855) 382-3257 for an assessment.
My 1960s ranch lot has an old septic system – can we still put a paver patio over that area?
Not directly over the leach field, no. Leach fields need to breathe, and sealing them under pavers can saturate the soil and fail the system. But you can often place a paver patio adjacent to or partially over the edges of a leach field with proper setbacks, hand-digging, and a permeable assembly. We verify the septic layout before we design the patio, not after the permit gets flagged. Call (855) 382-3257 for an exact quote on your lot.
Do Unilock installations in Saratoga need fire-resistant detailing near the wildland edge?
Yes, and this catches a lot of homeowners off guard. Properties in Saratoga’s wildland-urban interface zones fall under Santa Clara County fire-safe regulations. That affects paver work in two ways: you need an ember-resistant zone immediately around the structure, and you often need a fire department turnout and access path for emergency vehicles. Paver hardscape actually helps here because it’s noncombustible, but the assembly has to be designed with the fire access turning radius in mind. We build to those requirements from the start. Call (855) 382-3257 if you’re planning work near the wildland edge.
What does a paver driveway cost in Saratoga compared with concrete?
In Saratoga, a paver driveway runs $7,000 to $18,000 depending on slope, drainage work, and what’s under the existing surface. Concrete runs $4,500 to $12,000 for the same area. The paver cost includes a stronger base, better drainage behavior, and individual unit replacement if one cracks. Concrete is cheaper up front and harder to patch invisibly later. For a hillside lot where water moves fast, we generally recommend pavers with a properly built base. Call (855) 382-3257 for a line-item quote specific to your property.
