Unilock Construction in Mountain View, CA | Toolbox Contractors
We install and repair Unilock pavers, walls, and steps across Mountain View, from 94035 up to 94041, and also handle Unilock repair in Loyola. What makes our Unilock work different here is straightforward: we understand how Mountain View’s flat-roof Eichler runoff and expansive clay subgrades tear up paver installations, so we prep and drain for those specific conditions from day one. Call (855) 382-3257 for a free estimate. We tell you what the fix actually needs, not what the brochure says.
Why Mountain View Residents Choose Us for Unilock Service
Unilock is a premium paver system, and it deserves more than a generic install-and-go approach. Norm Castellano, our owner, grew up around half-built houses in the Muscoy area and spent years untangling bad contractor work before he ever hung a shingle here. His crew treats every Unilock driveway and patio as a small engineering job, not a weekend project. We’re an independent Unilock service provider. We are not authorized, sponsored, or endorsed by Unilock, and we don’t pretend otherwise. What we are is intimately familiar with the full Unilock paver and wall line, and we know what holds up in Mountain View’s specific soil and drainage reality better than an out-of-area crew reading a spec sheet.
We keep OEM-compatible Unilock pieces in our normal order rotation, and we source genuine Unilock pavers for repairs and expansions so color and texture blend with the existing field. When a full tear-out isn’t necessary, we re-level and re-sand rather than replace, and we’ll tell you straight when a spot repair won’t match an aged surface. That honesty saves you money and frustration. For a deeper look at our full Unilock sales & service experience, we break down our paver and wall capabilities in more detail there.

Common Unilock Construction Problems We Solve in Mountain View
These are the calls we take most often from Mountain View homeowners, and each one ties back to something specific about this city’s housing stock, weather, or soil.
- Driveway base failure and rutting over expansive clay. Older 94040 and 94041 tracts sit on Bay Area clay that was never engineered for modern vehicle loads. Contractors who skip proper over-excavation and recompaction leave you with a paver driveway that ruts within two or three winters. We fix the base first, then re-lay the pavers.
- Efflorescence and salt staining after wet winters. Mountain View’s November-through-April rains push minerals up through dense pavers like Brussels Block, and the white chalky residue left behind is stubborn. We clean it properly and seal where it makes sense, without pretending a quick power wash solves the underlying moisture path.
- Scupper discharge washing out driveways and patios. Flat-roof Eichler homes in 94040 dump concentrated roof runoff right onto paver surfaces. The discharge point erodes joint sand, shifts pavers, and creates standing water at the garage door. We re-pitch and add channel drains before relaying the field.
- Joint sand loss and paver shifting where runoff concentrates. Newer infill construction near downtown and Shoreline changes surface drainage patterns. Water that used to sheet broadly now channels across a paver patio or driveway, flushing joint sand and leaving loose pavers in its path.
- Color fade and surface scaling on Legacy and Beacon Hill pavers. Years of UV exposure plus occasional freeze-thaw nights in the North Bayshore wind corridor take a toll on older installations. We match aged pavers where possible and are honest when a full replacement is the only way to get a uniform look.
Unilock Service in Mountain View: What Local Conditions Mean for Your Equipment
On the flat-roof Eichler homes in 94040, winter storm runoff often overwhelms original interior downspouts and scuppers, so Unilock paver driveways and patios there frequently fail at the discharge point. This isn’t a generic drainage issue. The original Eichler builders routed roof water through interior downspouts, and when those clog or back up during a heavy December storm, the overflow dumps directly onto whatever sits below. We routinely re-pitch the paver base and add channel drains before re-laying pavers, a step that infill-only crews skip because they’ve never had to think about mid-century roofline drainage. Last December in the 94040 Eichler tract off Rengstorff Avenue, our crew tore out a heaved Unilock Brussels Block driveway where the original scupper dumped straight onto the pavers. We re-graded the base, tied the downspout into a new channel drain, and re-laid the field with fresh Brussels Block and matching edge restraints. The owner finally stopped getting standing water at the garage door. That’s the difference between someone who installs pavers and someone who installs them for Mountain View’s actual houses.
Unilock Models & Products We Service in Mountain View
We work across the Unilock paver and wall line that shows up most often in Mountain View yards and driveways. That includes Brussels Block, the dense, irregular-edged paver that dominates older Eichler-era patios; Beacon Hill, a tumbled paver that reads more formal and holds up well on covered patios; Legacy, a larger-format paver for driveways and pool decks where fewer joints matter; and Lineo, a clean-modern plank that fits the aesthetic of newer townhome and infill construction near downtown. When we repair, we source genuine Unilock pieces matched to the existing field. When we replace, we talk through the model’s actual performance in Mountain View’s clay, not just how it looks in a showroom photo. Our Mountain View service area coverage runs from Old Mountain View up through North Bayshore and across the 94035, 94039, 94040, and 94041 ZIP codes.

FAQs – Unilock Construction in Mountain View
Yes, in most cases, because paver joints allow water to move instead of pooling and cracking a monolithic slab. But that only holds true when the base is properly over-excavated and compacted, especially on Mountain View’s expansive clay. A poorly prepped paver driveway fails just as dramatically as cracked concrete, often in the form of ruts and shifting rather than slab cracks. Call (855) 382-3257 if you want us to look at your base before winter hits.
Unilock pavers handle runoff fine as long as the water has a managed path. Direct discharge from a scupper onto any paver surface will erode joint sand and shift pavers over time. We fix this by adding a channel drain at the discharge point, re-pitching the base so water moves away from the garage, and then relaying the pavers. The pavers themselves are not the weak link; the drainage plan is. Call (855) 382-3257 for an exact quote on a channel-drain retrofit.
We source genuine Unilock pieces from the same model line, then work the new pieces into the field so they don’t sit as an obvious patch. For installations where the old pavers have faded badly or the color lot has shifted, we’ll tell you honestly: a perfect match may not be achievable, and we’ll show you options before we start. An independent Unilock service provider isn’t obligated to sell you a fantasy of a seamless patch. Estimates are free at (855) 382-3257.
We over-excavate below the original subgrade, typically 10 to 14 inches depending on soil conditions, then recompact in lifts with angular aggregate before laying the paver bedding course. On 94040 and 94041 sites where the original subgrade was never engineered, this is the single most important difference between a driveway that lasts and one that ruts in two winters. We include the full base-prep breakdown in every written quote.
Often yes. We re-level and re-sand the affected section, replace cracked or spalled units with genuine Unilock pieces, and rebuild the wall segment with new geo-grid where needed. If the underlying footing has failed, we’ll show you why a section rebuild won’t hold, and we’ll quote the scope honestly. Call (855) 382-3257 and we’ll evaluate the wall or steps in person before recommending anything.
