Unilock Construction in Mountain View, CA | Penhallow Remodeling San Jose
We’re Penhallow Remodeling San Jose, and we provide independent Unilock paver and wall system service across Mountain View. We are not a Unilock dealer or an authorized manufacturer rep. What we are is a General Contractor in Mountain View with crews who have torn out and rebuilt enough failed hardscape in this city to know exactly what holds up on adobe clay, small lots, and fog-heavy mornings. Call (669) 274-2362 for a free estimate on Unilock work in Mountain View.
Why Mountain View Residents Choose Us for Unilock Service
The reason homeowners here call us is simple: we give you a written price before a single paver gets pulled, and that number is what you pay. Not an estimate range that balloons after demo day. A written number, backed by our 365-Day Done Right Promise. If the pavers shift, the edge restraint warps, or the joint sand washes out inside the guarantee period, we come back and make it right at no charge. That’s the Kingswell standard, and Trevor Nash, who leads our crew, has spent close to two decades running remodeling and hardscape projects across the South Bay, including some of the cleanest finish work he’s ever done on our Bathroom Remodeling in Mountain View and kitchen gut-jobs in San Jose’s Willow Glen neighborhood. He treats paver work the same way: written scope, firm number, plain explanation of what’s under the surface.
We stock genuine Unilock pavers and Unilock jointing sand for color-matched repairs throughout Mountain View. Because we’re independent, we’re free to recommend what actually works in your yard, not what a factory manual dictates. Our techs are background-checked and arrive in uniform, so you always know who’s at your door. And a live person answers our phone 24/7, not a voicemail prompt.

Common Unilock Construction Problems We Solve in Mountain View
- Concrete paver efflorescence on Brussels Block walkways. White mineral deposits bloom on Unilock Brussels Block surfaces when moisture wicks through the paver and evaporates, leaving salts behind. Mountain View’s fog-heavy mornings near the Bay, especially in the Cuesta Park and Old Mountain View neighborhoods, keep paver surfaces damp and make this worse than inland. We clean the surface and, more importantly, correct the drainage path so the moisture stops migrating through the paver in the first place.
- Polymeric sand failure between Mattoni pavers on small front yards. Mountain View’s small lots mean tight front yards with limited windbreaks. The Bay breeze scours joints, and once the top layer of polymeric sand erodes, water gets underneath and the pavers start shifting under foot traffic. We re-sand with Unilock jointing sand and address the edge restraints so the perimeter actually holds.
- Base settlement and heaving in Richcliff patios over adobe clay. Mountain View sits on expansive adobe clay that swells when wet and shrinks when dry. A Richcliff patio set on a shallow base will heave within two or three seasons. We excavate to proper depth, lay geotextile, and compact a high-performance local gravel base before relaying the pavers.
- Edge restraint warping on Town Hall borders. When sprinkler overspray keeps the edges of a paver installation perpetually wet, plastic edge restraints loosen and the paver bond fails. This is common on Mountain View’s ranch-style homes where irrigation systems run on tight timers close to the house. We replace plastic with aluminum edging that holds its line.
- Failed stamped-concrete driveways being converted to Unilock pavers. Many Mountain View homes built in the 1950s and 1960s have original concrete driveways that have cracked and heaved over the clay. We remove the old slab, build a proper base, and install Unilock pavers that flex with soil movement instead of cracking.
Our Unilock sales & service teams handle all of this work across the Peninsula, and we write a written guarantee on every repair.
Unilock Service in Mountain View: What Local Conditions Mean for Your Equipment
Here’s the thing about Mountain View that doesn’t get talked about enough: this city is built out. There’s almost no new land to develop, so every project is a negotiation with a small lot, a strict setback rule, and a front-yard paving cap that limits how much of your yard can be impervious surface. Mountain View’s 1950s ranch homes, especially in Old Mountain View, often have original concrete walkways and patios that cracked decades ago from adobe clay expansion. Owners want to replace them with Unilock pavers, but the city’s planning rules cap hardscape coverage. So we design permeable Unilock paver systems, open-graded base, wider joints, the whole approach, that meet Mountain View’s stormwater code without sacrificing curb appeal. This is not a generic hardscape project. It’s a Mountain View-specific problem with a Unilock-specific solution, and it’s one of the main reasons our page looks different from a factory brochure. If you’re within the Mountain View service area, we can walk your lot and tell you exactly what the paving limits mean for your project.
Unilock Models & Products We Service in Mountain View
We work on the full range of Unilock residential lines: Brussels Block, Mattoni, Richcliff, and Town Hall. Brussels Block is the classic tumbled paver with that old-world look, and it’s the one we see most often on Mountain View walkways. Mattoni is a good fit for driveways with its tighter joint pattern, and Richcliff works well for patios where you want a more contemporary, quarried-stone appearance. Town Hall is our go-to for borders and accent bands.
When it comes to parts, we carry genuine Unilock pavers and Unilock jointing sand so color matches are seamless and the repair work doesn’t void any manufacturer’s coverage on the new material. For base and edge materials, we often spec higher-performance local gravel and aluminum edging instead of OEM accessories, because those hold up better in Mountain View’s clay than the factory defaults. We repair individual pavers and re-sand joints whenever the base is stable. If the base has failed, we’ll tell you straight: a full lift-and-relay is the honest fix, not another patch job.

FAQs – Unilock Construction in Mountain View
In most cases, no. If the concrete has cracked from adobe clay movement, the slab is not a stable base for pavers. We remove the old concrete, excavate to proper depth, and build a compacted gravel base that will actually hold. Installing pavers over a failed slab just delays the same problem by two years. Call (669) 274-2362 and we’ll tell you what your patio actually needs, for free.
Mattoni. Its tighter joint pattern and dimensional consistency handle repeated vehicle loading better than more ornamental lines. We lay it in a herringbone pattern for driveways, which distributes the weight across more pavers and resists the shoving that straight-line patterns show after a few years of daily commutes. The base matters as much as the paver on Mountain View clay.
That white powder is efflorescence, mineral salts wicking through the paver as moisture evaporates from the surface. Cleaning it off without fixing the moisture path means it’ll be back next fog season. We solve it by correcting drainage around the walkway, improving the base so water moves down instead of up, and sealing only when appropriate. Long-term, the fix is drainage, not scrubbing.
Unilock pavers themselves are not permeable, but the system can be. We build permeable installations using open-graded base, wider joints, and proper edge design so water infiltrates through the joints and into the ground below. That’s the approach that meets Mountain View’s impervious surface caps while still giving you a paver surface you can actually walk on and park on.
The joints wash out because the edge restraint is failing or missing, and water is moving through the installation instead of around it. Small Mountain View front yards catch the Bay wind directly, which accelerates sand erosion once the top protective layer is gone. We fix it by replacing the edge restraint with aluminum, re-sanding with Unilock polymeric sand, and compacting so the sand locks properly. Call (669) 274-2362 for an exact quote, estimates are free.
