Unilock Construction in Sunnyvale, CA

Unilock Construction in Sunnyvale, CA | Milpitas Construction

We provide independent Unilock paver installation and repair across Sunnyvale, and the service is built around one thing most contractors miss here: your paving plan has to bend around protected trees and slab-on-grade rebuild lots, not the other way around. If you’re putting in a paver driveway, patio, or replacing a failed one on a 6,000 – 8,000 sq ft infill lot, we handle the base, the drainage, the edge restraint, and the tree-ordinance setbacks from day one. We buy and set genuine Unilock product directly, answer to you and the City of Sunnyvale, not the factory. Call (877) 752-4194 for a free estimate.

Why Sunnyvale Residents Choose Us for Unilock Service

Ken Stafford grew up near the Milpitas BART station when that corridor was mostly warehouse lots, and he’s spent two-plus decades building in the South Bay. That means we show up to a Sunnyvale paver job already knowing what the soil, the drainage rules, and the tree ordinances will do to your project. We’re a full-scope general contractor, not a paver-only crew: the same team managing your Unilock driveway can also handle the roof, windows, kitchen, or ADU that’s part of the same rebuild. One accountable partner, one contract, and we spec materials by name so you know exactly what’s going into your home. Our Unilock sales & service work covers genuine Brussels Block, Beacon Hill, Town Hall, and Cambridge Paving Stones, with matching edge restraints and joint sand, not whatever generic block the big-box store happens to stock.

Common Unilock Construction Problems We Solve in Sunnyvale

Here’s what actually goes wrong with Unilock pavers on Sunnyvale lots, and why:

• Efflorescence bloom on gray-toned pavers. On tight Sunnyvale lots, downspouts and drip lines often dump onto the same narrow strip as the paver edge. That keeps the base saturated, and salts migrate up through the paver face as a white chalky haze. We fix the drainage first, then treat the bloom; otherwise it comes back.
• Polymeric sand joint failure after atmospheric-river storms. When a paver driveway gets laid over the old compacted subgrade from the original 1950s slab driveway, without a fresh, properly drained aggregate base, the rare winter storm exceeds what that base can move. Joints wash out, sand pumps up, and pavers start rocking. We re-base and relay, not just re-sand.
• Edge restraint heave and paver spread on rebuilt driveways. During a teardown-and-rebuild, the original slab-edge grade often never gets re-cut for the new paver elevation. The edge restraint sits too high or too shallow, and after a few seasons the whole border starts to drift. We cut the grade properly before the first paver goes down.
• Faded or chipped surfaces from construction traffic. On lots with radiant-heated slab demo and constant ADU construction access, pavers take a beating before the project’s even done. We sequence paver work after the heavy phase or protect the finished surface during phased builds.
• Root-zone heave under existing patios. Sunnyvale’s protected valley oaks and redwoods don’t stop growing because a patio’s already there. We’ve seen pavers lift and crack where roots were ignored in the original install. The fix starts with an arborist’s line on the root zone.

Unilock Service in Sunnyvale: What Local Conditions Mean for Your Pavers

Sunnyvale is ground zero for the demolition-and-rebuild cycle of mid-century Eichler-style and 1950s-60s ranch tract homes. The original houses in Fairbrae and the tracts near downtown sit on shallow slab foundations with radiant heating loops, and when those come out, the new build goes up on a re-graded lot with new drainage patterns the old paver work was never designed for. That’s the part that matters for Unilock work. A paver driveway that held for twenty years on the original lot can fail in two wet seasons behind a new two-story infill home, because the new roofline concentrates runoff right where the old driveway used to be. We see it regularly in the Fairbrae Eichler rebuilds. The paving plan has to be re-drawn for the new grade, the new downspout locations, and the new slab elevations, and that’s exactly the work we quote. On a rebuild off Fairbrae, our crew pulled up a failed asphalt apron and set a Brussels Block driveway with a fresh compacted aggregate base and slotted edge restraint, after the arborist fenced off the root zone of a protected oak at the property line. We re-graded the fall toward the street so the rare winter storm runoff wouldn’t pool against the new slab. Those pavers have held their joints through two wet seasons since.

Unilock Models & Products We Service in Sunnyvale

We set and repair the Unilock lines that fit Sunnyvale’s architectural stock and lot scale: Brussels Block for driveways and front aprons, Beacon Hill and Town Hall for patios and walkways, and Cambridge Paving Stones where a more uniform face reads better against a contemporary rebuild. We use genuine Unilock pavers and their matching edge restraints and joint sand, because the unit dimensions and interlock tolerances drive the finished pattern; generic blocks from a different mold won’t seat the same way, and the joints telegraph it within a year. We stock common Unilock replacement units locally for fast Sunnyvale turnarounds, and when a patio is failing on base rather than stone, we tell you honestly: re-base and relay is often the cheaper fix. Full replacement only makes sense when the units themselves are spalling or the grade can’t be corrected. If you’re in Sunnyvale and need Unilock pavers matched, serviced, or newly installed, we’re your Sunnyvale service area team.

FAQs – Unilock Construction in Sunnyvale

Can you install Unilock pavers around a protected valley oak on my Sunnyvale lot?

Yes, but the paving plan gets redrawn around the tree, not the other way around. Sunnyvale’s tree ordinance puts valley oaks and redwoods under arborist review, so a patio or driveway footprint often has to be pulled back from the protected root zone and re-graded. That changes the square footage, the edge restraint layout, and sometimes the paver pattern. We handle the arborist coordination as part of the scope. Call (877) 752-4194 for a site walk and a quote that accounts for the tree first.

My Fairbrae Eichler driveway pavers are sinking and the joints wash out every winter – what’s wrong?

Nearly always, the base is failing, not the pavers. The original Fairbrae Eichler driveways sat on the same compacted subgrade as the slab, and when you lay Unilock pavers directly over that without a fresh, properly drained aggregate base, the first atmospheric-river storm overwhelms it. Joints wash out, the base pumps, and the pavers sink. The fix is removal, a proper base rebuild with edge restraint, and re-laying the same units if they’re still sound. Call (877) 752-4194 and we’ll tell you whether it’s a re-base or a full replacement, honestly.

Do you need a permit to install a Unilock paver driveway in Sunnyvale?

In most Sunnyvale cases, a paver driveway replacement on the original footprint doesn’t trigger a building permit, but a new or expanded driveway can, and any work near a protected tree needs arborist review regardless. We check the current Sunnyvale requirements as part of every quote and handle the permit process when it’s needed.

Can you match my existing Unilock pavers when I add a patio to a rebuilt home?

Yes, we match Unilock paver lines by model family: Brussels Block, Beacon Hill, Town Hall, Cambridge Paving Stones. The catch on rebuild lots is that a paver patio poured years ago may be too weathered or faded to match a new batch cleanly. We’ll tell you if a full relay or a re-pattern makes more visual sense. We set genuine Unilock product, never generic blocks, so the interlock tolerances stay consistent.

How do you handle storm drainage on a paver patio behind a new two-story infill home?

We re-grade the entire patio area for the new roofline and downspout locations before the first paver goes down. A two-story infill home concentrates more runoff onto the same square footage than the original single-story, so the base has to be built to move that water, not just hold the pavers. That means a properly compacted aggregate base, the right fall, and edge restraints that won’t heave. Call (877) 752-4194 for a drainage check with your paver quote.
