AfterUnilock Construction in Mountain View, CA | Rowan Construction Group Sunnyvale
We provide independent Unilock hardscape installation and repair across Mountain View, with crews who understand the specific soil and permit conditions that separate a lasting paver driveway from one that settles in two seasons. The one thing that makes our Unilock work here different: we routinely build on former ranch-home teardown lots where demolition fill and disturbed bay-mud soils demand base reconstruction that standard spec sheets don’t address. Call (650) 405-3637 to schedule your free written estimate.
Why Mountain View Residents Choose Us for Unilock Service
We’ve installed and repaired Unilock hardscape systems across the Peninsula and South Bay since 2007, and our crews know the difference between a proper compaction schedule and a paver patio that will shift after one wet winter. In Mountain View specifically, we’ve handled everything from Brussels Dimensional Stone driveways on rebuilt ranch lots to Umbriano patios for Eichler-influenced homes near the Rex Manor neighborhood, and we’re also available for our Kitchen Remodeling in Mountain View.
Grant Rowan, our owner, trained in construction technology at Santa Monica College, where coursework covered structural load calculations and site safety - fundamentals he still references when scoping a job today. That background shows up in how we write our estimates: material costs, labor hours, and subcontractor scope listed separately so you know exactly where each dollar goes. We source genuine Unilock replacement pavers whenever possible, and we use only quality aftermarket grading aggregates, polymeric sand, and edge restraints that meet or exceed manufacturer spec. We won’t pass off mismatched stock as a match.
We are an independent contractor and are not authorized, sponsored, or endorsed by Unilock. Our Unilock sales & service is built on direct product knowledge and documented field experience, not a dealer agreement. Every project gets a flat written price before work begins, backed by our 365-Day Done Right Promise. “Measure it twice, write it down, then build it.” That’s how we work.
Common Unilock Construction Problems We Solve in Mountain View
- Differential settlement and rutting in paver driveways - This happens when base is placed over loose demolition fill from a torn-down ranch slab without re-compaction or over-excavation. In Mountain View, where teardown-and-rebuild is economically routine on $1.5M-$2M+ lots, we see this constantly on Brussels Dimensional Stone and Copthorne driveways installed by crews who treated the site like undisturbed soil.
- Sand-joint erosion and sporadic joint washout on bay-facing patios - The North Bayshore and Shoreline corridor gets heavy marine layer moisture summer mornings plus winter rain, and that combination drives sub-base fines migration through improperly sealed joints. Beacon Hill Flagstone patios in this zone need polymeric sand rated for saturated conditions, not standard kiln-dried jointing.
- Edge restraint failure and toe kick-out at driveway aprons - When pavers spread at the perimeter because plastic or concrete edge restraints were undersized or base settled, you get the characteristic kicked-out row. This is especially common at apron transitions on older 1950s-60s ranch neighborhoods where original driveways were narrow and new layouts widen the footprint without adequate structural support at the margins.
- Freeze-thaw spalling and surface scaling on lower-density tumbled pavers - Mountain View’s climate is nearly frost-free, but shaded north-facing areas in the foothill zones toward Los Altos stay damp longer. Tumbled products like older Brussels Dimensional runs can show surface degradation where sealing was skipped and moisture lingers for weeks.
- Premature color loss and efflorescence on newer installations - Umbriano and other smooth-finish pavers in shaded, damp locations develop white mineral bloom when vapor drive pushes soluble salts to the surface. The fix is proper sealing at installation and correct drainage design, not a topical cleaner after the fact.

AfterUnilock Service in Mountain View: What Local Conditions Mean for Your Equipment
In Mountain View, a large share of the hardest Unilock work we do is not on untouched ground but on lots where a 1950s-60s ranch home was torn down: the original slab and utility trenches leave loose, non-uniform fill that must be re-compacted or over-excavated before any paver base is placed, and that condition is far more common here than in neighboring Sunnyvale or Santa Clara. The land value simply exceeds the structure’s value by enough to make wholesale demolition routine, which means we’re regularly called to jobs on Rex Manor streets or near Old Mountain View where the previous contractor poured base over demolition debris and called it graded aggregate. Many of these same homeowners later ask about our Bathroom Remodeling in Mountain View.
The North Bayshore and Shoreline corridor sits on engineered bay fill and compressible bay mud, requiring geotechnical investigation and deep foundation systems for any significant structure. For hardscape, that translates to unexpected settlement patterns that standard 6-inch base courses won’t handle. We factor this into our Mountain View service area estimates, and we document the substrate condition with photos before any base goes in. The customer leaves with evidence of what was found and what was done.
There’s also the permit reality. Contractors pulling permits through Mountain View’s Community Development department during active phases of Google’s North Bayshore approvals often report longer-than-usual plan-check queues, since the same staff reviews both the city’s largest-ever mixed-use entitlements and routine residential remodel permits simultaneously. We schedule our submittals with that capacity crunch in mind, and we advise Mountain View clients to build extra lead time into their project calendars.
Unilock Models & Products We Service in Mountain View
We work with the full Unilock residential line, with particular depth on the products most common in Mountain View’s housing stock:
- Brussels Dimensional Stone - Tumbled, three-piece modular pavers, the default choice for Mountain View driveways and walkways on rebuilt ranch lots. We stock common earth-tone blends for repair work.
- Beacon Hill Flagstone - Flagstone-look pavers widely used for patios and pool decks; the textured surface handles marine-layer moisture better than smooth finishes in bay-facing locations.
- Umbriano - Large-format smooth pavers frequently specified for modern ranch rebuilds and Eichler-adjacent patios where clean lines matter. Requires precise base prep because the large units telegraph any substrate irregularity.
- Copthorne and Town Hall - Clay-brick-look pavers often chosen for driveways in the older 1950s-60s ranch neighborhoods where homeowners want period-appropriate aesthetics without the maintenance of actual clay brick.
For repairs, we source genuine Unilock replacement pavers to match color, size, and profile. If a hardscape is settled or failing over a broad area, partial repair is usually a false economy and full re-lay over a corrected base is the honest recommendation.
Unilock Service Pricing in Mountain View
Our written quotes break out material, labor, and equipment separately. For Unilock hardscape work in Mountain View, typical ranges are:
| Service | Price Range |
|---|---|
| Paver Driveway Installation | $7,000-$18,000 |
| Paver Patio Installation | $3,500-$11,000 |
| Driveway Replacement | $5,000-$14,000 |
What drives cost: site access, the condition of existing substrate or fill, whether demolition and haul-off is included, and the complexity of edge conditions and drainage. A teardown lot with 10 inches of over-excavation and geotextile separation runs higher than undisturbed soil. Every estimate includes a documented photo record of site conditions, a written scope, and our 365-Day Done Right Promise. Under Clause 1 of the Haven Standard, the price is written before anyone starts. Call (650) 405-3637 for your exact quote - estimates are free.

FAQs - Unilock Construction in Mountain View
Yes. The original slab and utility trenches leave loose, non-uniform fill that standard base prep won’t address. We over-excavate, re-compact in lifts, and often install geotextile separation before placing aggregate. On a teardown-rebuild lot near the Rex Manor neighborhood, our crew removed a failing Brussels Dimensional Stone driveway where the pavers had settled 1 to 1.5 inches in wheel paths because the original installer had placed base directly over demolition fill from the old ranch slab. We over-excavated 10 inches, re-compacted in lifts, installed a geotextile separation layer and a fresh aggregate base, then re-laid the salvaged and new Unilock pavers with a proper edge restraint and polymeric joint sand - the driveway has stayed flat through two wet seasons. Call (650) 405-3637 for a site-specific assessment.
Yes, if standard kiln-dried sand is used. The summer marine layer in the North Bayshore and Shoreline corridor keeps joints damp for hours each morning, which accelerates washout and sub-base fines migration. We specify polymeric sand rated for saturated conditions on all bay-facing Mountain View installations. Call (650) 405-3637 to discuss jointing specifications for your specific site.
We source genuine Unilock replacement pavers whenever possible to match color, size, and profile. If the original product line has been discontinued, we’ll show you the closest current match and document the difference in writing before any work proceeds. We won’t pass off mismatched stock as a match. Call (650) 405-3637 and we can review your existing installation.
Mountain View’s Community Development department handles both Google’s North Bayshore mega-campus entitlements and routine residential permits with the same staff, which creates longer-than-usual plan-check queues during active approval phases. We schedule our submittals with this capacity crunch in mind and advise building extra lead time into your project calendar. The permit is included in our scope and pricing. Call (650) 405-3637 for current timeline estimates.
