Unilock Construction in Mountain View, CA | Ashford Contractors
We provide independent Unilock hardscape installation and repair across Mountain View and Los Altos Hills Unilock service, from paver driveways and patios to seat walls and planter systems. The thing that separates our Unilock work here from anywhere else on the Peninsula is this: Mountain View’s flat and low-slope roofs dump concentrated storm water directly onto hardscape during atmospheric-river events, so paving here is a drainage and base-depth job first, and a paver job second. We buy genuine Unilock units, base aggregates, and Unilock polymeric sand, and we build to the manufacturer’s published installation specs. Call (877) 752-3868 to schedule a free estimate.
Why Mountain View Residents Choose Us for Unilock Service
Most hardscape crews in Mountain View can lay pavers. Few can explain why your Brussels Block drive rutted at the garage apron while your neighbor’s did not. We’ve installed and repaired Unilock systems across the Peninsula for years, including Unilock repair in Los Altos, and we know how the 94040 and 94041 neighborhoods specifically punish flat work. Glen Mossier, our owner, grew up in Foster City’s Marlin Cove watching lagoon-side homes get rebuilt after water damage, and he brought that same fixation on drainage and base prep to every Unilock job we take. We are an independent crew, not Unilock-authorized and not manufacturer-affiliated. Our credibility comes from finished drives and patios that hold up through Mountain View’s wet winters and long dry summers, not from a dealer badge.

Common Unilock Construction Problems We Solve in Mountain View
- Rutting and lipping at drive aprons and garage transitions. Mountain View’s postwar soils were never over-excavated and compacted to the depth Unilock pavers require. When the base gives way, the pavers shift as a plane. We see this most often on ranchers off El Camino where the original drive was poured decades ago and the base beneath it was never engineered for paver loading.
- Polymeric joint sand washing out after dry summers, then atmospheric-river downpours. Months of sun bake the joints, and when the first winter storm hits, concentrated roof runoff finds every weak seam and flushes the sand out. Once the sand is gone, the base beneath starts eroding and the pavers begin to move.
- Efflorescence bloom and salt staining on Brussels Block. This shows up after wet-season cycles, especially where the base drains toward the house instead of away. It’s cosmetic, but it signals a drainage problem that will eventually undermine the installation.
- Bristol Valley and Bristol Renaissance wall unit settlement and cap separation. We see this on seat walls and planters built against Eichler-era flat-roof lots where roof runoff discharges directly onto the hardscape. The concentrated water erodes the base beneath the wall, and the caps start separating.
- Edge spalling at paver borders. Where edge restraint is missing or was installed as an afterthought, the perimeter pavers chip and fracture under point loads. In Mountain View, this happens fastest at drive apron corners where cars cut the turn tight.
Unilock Service in Mountain View: What Local Conditions Mean for Your Equipment
Mountain View’s mid-century flat and low-slope roofs pond water and fail at seams when the first atmospheric-river storms hit. What that means for your hardscape is straightforward: roof water does not disappear when it reaches the ground. On ranch and Eichler-style homes in the 94040 and 94041 neighborhoods, downspouts and scuppers discharge directly onto driveways and patio aprons, so the pavers become the roof’s drain whether you planned for it or not. Unilock installations here have to be graded and edge-restrained to route that roof water away, not absorb it. The paver is the finish surface. The grading, base depth, and edge restraint are the actual drainage system. Skip those, and you’ll be re-lifting and re-compacting within three wet seasons. Build it right the first time, and you won’t be rebuilding it in ten years.
Unilock Models & Products We Service in Mountain View
We work with the full Unilock paver and wall lineup you’re likely to see on Mountain View properties. Brussels Block, the tumbled dimensional paver, shows up on driveways and aprons throughout the older neighborhoods. Beacon Hill, the flagstone-style paver with irregular edges, is common on patios and walkways. For seat walls and planters, we work with Bristol Valley and Bristol Renaissance tumbled wall and cap units. Town Hall, the slab-style paver, fits the low-profile modern hardscape you see on newer infill projects near downtown and Unilock in Sunnyvale. On every job, we specify genuine Unilock units and Unilock-branded polymeric sand so the color, chamfer, and joint spec match warranty expectations. For base and drainage, we use quality compatible aggregates and edge restraint rather than knockoff lookalikes. We stock common Brussels Block and Beacon Hill replacement units locally for faster Mountain View turnaround, and we can order any Unilock product line in for larger work.

What moves the price in Mountain View is base work. If the existing base under a paver drive was never compacted to depth, we’re excavating and rebuilding it before a single paver goes down. That’s most of the labor on the older ranch properties. A free estimate from us includes an on-site look at your drainage, a base-depth assessment, and a written line-item quote. Call (877) 752-3868 for an exact number for your property. Estimates are free.

FAQs – Unilock Construction in Mountain View
The original base under most postwar driveways in Mountain View was never over-excavated and compacted to the depth Unilock pavers require, so when concentrated roof runoff and vehicle loading combine, the base fails and the pavers shift as a plane. We fix it by over-excavating, re-compacting to manufacturer spec, and regrading so water sheds away from the garage. Call (877) 752-3868 for an evaluation.
No. Efflorescence is a cosmetic salt bloom that appears when water moves through the paver and evaporates at the surface. It’s common after Mountain View’s wet winters, and it signals a drainage issue beneath the surface. Fix the drainage, clean the bloom. The pavers are fine. We can assess your base drainage and recommend the right correction.
Yes. Hardscape additions are routinely folded into the same permit package as a home addition or ADU in Mountain View, and we handle the hardscape scope alongside the structural work. That’s the advantage of one contractor on the job. Call (877) 752-3868 to discuss your project scope.
They hold when the base beneath them is solid and the hardscape is graded to shed roof water. The sand fails when the base erodes or when concentrated downspout discharge flushes through the joints. We specify Unilock-branded polymeric sand and verify drainage before and after install. Call us for a joint assessment if your sand is washing out.
Expect $7,000 to $18,000 depending on square footage, access, and how much base rebuild is needed. On older Mountain View properties where the original base was underbuilt, the excavation and re-compaction is the bulk of the cost.
