Why Mountain View Residents Choose Us for Unilock Service

We’re not a landscaping crew that dabbles in pavers. We’re a Mountain View General Contractor that’s set Unilock product on lots ranging from 1920s downtown bungalows to mid-century Eichler homes on the west side, and we’ve learned exactly how this city’s soil and drainage behave. That experience matters when a Beacon Hill driveway starts lipping at the apron after one wet winter, or when Brussels Block walkway pavers bloom white after the first rains and the homeowner thinks the product failed. Most of the time the product didn’t fail. The base did.

Ruben Castillo, our owner, grew up watching his uncle frame garages and reroof houses on a tight budget, which taught him early that the work you can’t see is the work that keeps the project alive. That’s the same philosophy we bring to Unilock pavers in Mountain View: if the subgrade moves, nothing you lay on top of it matters.

We’re an independent Unilock installer, not authorized, sponsored, or endorsed by Unilock. That independence means we call it straight. When a repair makes sense, we say so. When the base is gone and a patch would be throwing your money away, we tell you that too.

Common Unilock Construction Problems We Solve in Mountain View

• Efflorescence on Brussels Block and other wet-cast pavers: Mountain View’s first winter rains push moisture through pavers that were laid over a base that never drained properly. That white powdery bloom often gets misread as a product defect. It’s usually moisture migrating through a saturated base, and the fix starts below the paver, not on its surface.
• Polymeric sand washout where a walkway or patio sits tight to a bungalow foundation: Many older downtown Mountain View homes in 94041 have hardscape laid within inches of foundation walls with no positive slope away from the house. Water channels between the paver and the foundation, eroding the joint sand until the pavers loosen and shift.
• Settling and lippage on Beacon Hill driveways over expansive North County clay: When a driveway is laid over undisturbed clay without proper over-excavation and recompaction, the surface looks fine until spring. Then the clay’s shrink-swell cycle does its thing and the pavers heave or dip, creating trip hazards at the apron.
• Edge restraint failure and paver spread at driveway aprons: On sloped west-side lots in 94040, we regularly see edge restraints that weren’t anchored deeply enough or weren’t installed at all, so the paver field drifts toward the street over a couple of seasons, especially where the driveway ties into existing flatwork.
• Mismatched paver replacement from prior contractors: We’ve walked onto Mountain View properties where a previous installer dropped in a different manufacturer’s paver to patch an old Uni-Stone patio. Different dimensions, different color, different texture. We won’t do that. We buy genuine Unilock units for the visible field and matching edge components.

Unilock Service in Mountain View: What Local Conditions Mean for Your Hardscape

The single biggest factor in whether a Unilock paver installation in Mountain View survives is what’s underneath it. This city sits on clay-heavy North County soil that expands when wet and shrinks when dry. Combine that with a rain-shadowed but real wet season, and you get a shrink-swell cycle that moves ground more than most homeowners realize. A driveway or patio laid on a thin sand bed over undisturbed clay will fail here. Not might fail. Will fail. We’ve pulled enough failed Beacon Hill and Brussels Block installations on the west side to know the pattern cold: surface looks fine for a year or two, first heavy rains arrive, and by spring the pavers are lipping at the apron or separating along the foundation line.

On west-side Eichler-era lots, there’s an additional constraint. Those flat-roof homes often have existing flatwork, radiant slab edges, and lot grading that can’t be freely re-sloped to drain a new paver field. The hardscape has to tie into what’s already there, which means the base design has to account for water that already collects in ways the original 1960s builder never planned for. Off Wilkie Way in 94040, we replaced a Beacon Hill driveway that had heaved and lipped at the apron after two wet winters. When we pulled the field, the original installer had laid pavers on a thin sand bed over undisturbed expansive clay with no geotextile fabric. We over-excavated, recompacted in lifts with separator fabric, re-set the edge restraint, and reinstalled on a proper base with positive slope to the street. That driveway has now gone through two storm seasons with no movement. The paver was never the problem. What was under it was.

Unilock Models & Products We Service in Mountain View

We work with the full range of Unilock installed product here. Brussels Block shows up a lot on downtown Mountain View bungalow walkways in 94041, where its tumbled, dimensional look matches the older architecture. Beacon Hill is the workhorse for west-side driveways and patios in 94040. We also service older Uni-Stone installations on patios and pool decks throughout the city as part of our Home Remodeling in Mountain View. On high-end rebuilds, particularly teardown-and-rebuild projects near the Googleplex, we’ve replaced dated slab pavers with Unilock’s Elegance and other large-format series to match the scale of newer custom homes.

When a repair requires matching paver units, we source genuine Unilock product, not a different manufacturer’s paver dropped in to save a few dollars. We stock common edge restraint components and jointing materials for fast Mountain View turnaround, but we order field units per project to match existing color and texture. If the base and drainage are sound, we pull, re-set, and re-sand affected pavers. If the base has failed, we say so plainly. Patching the surface over failed subgrade is money thrown away.

FAQs – Unilock Construction in Mountain View

Why does my Unilock driveway in Mountain View heave and lip at the street apron every spring?
That heaving at the apron is almost always expansive clay under the base going through its shrink-swell cycle. The pavers didn’t fail. The subgrade moved because it wasn’t over-excavated, recompacted, and separated properly during the original install. The fix is pulling the field, rebuilding the base with separator fabric and compacted lifts, and re-setting the pavers with a positive slope to the street. Call (855) 473-5620 and we’ll inspect your driveway base before you spend money on surface patches that won’t hold.

Is white powdery bloom on my Brussels Block pavers a defect?
No. Efflorescence on Brussels Block in Mountain View is moisture carrying minerals through the paver after the first winter rains, and it usually means the base isn’t draining properly. It’s often misread as a manufacturing flaw. Once the drainage under the paver is corrected and the pavers are cleaned with the right product, the bloom doesn’t keep coming back. If it recurs every season, the base is the issue, not the paver.

Can you match new Unilock pavers to an existing patio that’s only partly failing?
If the field is otherwise sound and the base and drainage are in good shape, we’ll pull the affected area, re-set with matching genuine Unilock units, and re-sand the joints. Matching older Uni-Stone or Beacon Hill color can take some sourcing, but we won’t substitute another manufacturer’s paver into a Unilock field just to close the job faster. If the base has failed under a portion of the patio, we’ll tell you that patching is a short-term fix and give you a straight answer on full replacement cost. Estimates are free, so call (855) 473-5620.

How does the flat-roof Eichler housing stock on the west side affect a paver project?
Eichler-era lots in 94040 often have existing flatwork and radiant-slab edges that can’t be re-graded freely, plus drainage patterns that were set in the 1960s. That means a new paver patio or driveway has to tie into existing concrete and work with the original site grading. We design the base and drainage around those constraints rather than pretending the lot is a blank slate. It’s more planning up front, but it’s why the work holds up.

Do you install Unilock over an existing concrete driveway in Mountain View?
Sometimes, yes, but only when the concrete is structurally intact with no significant cracking or movement. In Mountain View, where expansive clay moves concrete slabs, most existing driveways aren’t candidates for an overlay, and installing pavers over a slab that’s already moving just transfers the movement to the paver. We’ll assess the slab during a free estimate and tell you honestly whether an overlay makes sense or whether full removal and a proper base is the right call. Call (855) 473-5620 to schedule a look.
