Unilock Construction in Sausalito, CA | San Bruno Construction
We provide independent Unilock paver, wall, and step installation and repair across Sausalito as a Sausalito General Contractor, and we’re one of the few contractors here who plans every job around the hillside reality: narrow lanes, steep grades, and limited staging. The pavers matter, but in Sausalito the base drainage and material-handling plan decide whether the work holds. Call (866) 472-1908 for a free estimate on any Unilock patio, driveway, or retaining wall project. We specify genuine Unilock product, we’ve worked the hillside lots above Bridgeway for years, and we coordinate the whole job under one contract.
Why Sausalito Residents Choose Us for Unilock Service
We know how Unilock materials perform when a Sausalito winter puts them through fog, salt air, and rain driven against a hillside exposure. Flat-lot installers don’t get the same test. Noel Carvalho, our owner, grew up off El Camino Real in San Bruno and trained in construction technology at Skyline College before running residential projects across Marin and San Mateo counties for more than two decades. He learned to read load paths and drainage before ever touching a paver, and that’s the background we bring to every Unilock sales & service job. We’re an independent contractor, not a manufacturer affiliate. That means we specify Unilock because it performs, and we build the base, drainage, and edge restraint that actually keep it performing.
Our crew has installed Unilock Brussels Block, Pisa2, Beacon Hill Flagstone, and Lineo Stone on lots where a concrete truck never gets closer than the road below. We stage material where it can be staged, move it up by hand or conveyor, and excavate to a proper open-graded base with a real drainage outlet. That’s the difference between a paver field that sheds water and one that pumps after the first wet season. We serve all of Sausalito service area, including 94965 and 94966.

Common Unilock Construction Problems We Solve in Sausalito
- Settled, rocking pavers after winter rain. Water sheeting down a Sausalito slope erodes uncompacted base aggregate fast. Pavers start rocking and joint sand washes out. We re-excavate, compact a proper open-graded base with drainage, and re-set the field so water moves away from the house and the slope face.
- Efflorescence and salt staining. Marine fog off Richardson Bay deposits salt on unsealed pavers and drives white efflorescence bloom through capillary action. We clean, correct the joint-sealing issue, and apply a breathable sealer where the exposure calls for it.
- Leaning or bulging Pisa2 and Lineo retaining walls. On tight hillside lots, walls built without geogrid reinforcement and a drainage column behind the face collect saturated soil load. The wall leans. We rebuild with proper reinforcement and a drainage outlet, which is what the original install should have had.
- Polymeric sand failing in shaded north-facing yards. Winter rain driven against hillside exposures soaks unsealed joints, and the sand cures unevenly in shaded conditions. It crumbles and migrates. We time joint work for a dry window and use a sand that suits the specific exposure.
- Driveway aprons cracking where slope meets flat. The transition from a steep Sausalito lane to a driveway apron concentrates water and load. If the sub-base wasn’t built for it, the edge units crack or sink. We rebuild that transition with edge restraint and a compacted base that handles the grade change.
Unilock Service in Sausalito: What Local Conditions Mean for Your Equipment
Sausalito’s hillside lots climb above Bridgeway on narrow winding lanes where concrete trucks, dumpsters, and lifts often can’t reach the work area. That changes a Unilock job in a way no flat-lot city deals with. A paver patio or driveway here is really a material-handling and staging plan: pallets get staged on Bridgeway or a driveway apron, then moved up by hand or conveyor before a single unit goes down. In the Banana Belt hillside streets, this isn’t a convenience issue, it’s the whole job. The handling plan determines access, the drainage plan determines whether the base survives the first rainy season, and both determine whether the pavers stay tight. Good construction doesn’t announce itself: it just works, year after year. And if you’re on a steep lot above Bridgeway, the plan has to be built for Sausalito, not Marin City Unilock service.
Unilock Models & Products We Service in Sausalito
We install and repair the Unilock lines that hold up on Marin hillsides: Brussels Block tumbled concrete pavers, Beacon Hill Flagstone for a flagstone look, Pisa2 retaining wall systems, and Lineo Stone modular wall block. We use genuine Unilock pavers, wall units, matching edge restraints, and their polymeric joint sand, not generic substitutes. Color-through body and dimensional tolerances keep a slope-side install tight, and that’s always worth the difference. If a field is only settled or a wall is losing cap units to a drainage flaw, we repair and re-detail the base before recommending replacement. The material usually outlasts the failed sub-base.
We stock the standard joint materials and edge restraints locally so Sausalito turnaround is measured in days, not weeks. If a few Brussels Block units spalled or a Pisa2 cap cracked, we don’t have to wait on a full pallet to get the repair moving.

AfterUnilock Service Pricing in Sausalito
Sausalito pricing runs toward the higher end of these ranges because of access, staging, and slope work. A patio on a flat Mill Valley lot does not carry the same handling cost as a hillside field above Bridgeway where every unit moves by hand. Here’s what we quote across Sausalito:
| Unilock Service | Price Range |
|---|---|
| Paver Patio Installation | $3,500 – $11,000 |
| Paver Driveway Installation | $7,000 – $18,000 |
| Driveway Replacement | $5,000 – $14,000 |
| Driveway Sealing | $250 – $700 |
What drives the number: slope grade, access for material, the drainage work required, and the paver line you choose. Our free estimate walks the lot with you, checks where water goes, and gives you a written line-item quote before any work starts. Call (866) 472-1908 to schedule yours.

FAQs – Unilock Construction in Sausalito
Yes, but not with a standard truck delivery. We stage pallets and aggregate on Bridgeway or at the nearest driveway apron, then move material up by hand or conveyor. The handling plan is part of the estimate, and on the tightest hillside lanes it’s often the single largest labor line. Call (866) 472-1908 and we’ll walk the lane with you to see what’s workable.
Because the base wasn’t built for slope drainage. Water sheeting down a paved surface erodes uncompacted base aggregate and washes out joint sand. The fix is open-graded base, compaction, and a drainage outlet, not just re-setting pavers.
It accelerates staining and efflorescence on unsealed units. The concrete itself holds up, but the surface needs proper joint sealing and sometimes a breathable sealer. We correct the joint issue first, then seal where the exposure calls for it.
Yes, with shoring, stepped base, and geogrid reinforcement behind the wall face. The slope and lot lines control what’s buildable, and we pull permit-required staging plans when the city asks for them. Every wall we build has a drainage column and outlet behind it, which is what prevents lean and bulge.
A paver patio typically runs $3,500 – $11,000 and a paver driveway $7,000 – $18,000 here. Hillside access and drainage work push most Sausalito jobs toward the upper end. Call (866) 472-1908 for an exact quote after we walk the lot, estimates are free.
