Why Los Gatos Residents Choose Us for Unilock Service

Grant Rowan built this company on a discipline he learned at Santa Monica College’s construction technology program: read the drawing, price the work, then don’t touch a tool until the customer has both in writing. That was 2007. Since then, Rowan Construction Group has delivered 4,000-plus projects across the South Bay, every one with a flat written price before work started and a documented photo record when the crew left.

Our Unilock sales & service work in Los Gatos is different because the terrain is different. We’ve reset Brussels Block on heaved driveway aprons above Highway 17, re-leveled Umbriano pool decks softened by hillside fog, and engineered Pisa2 retaining walls for graded lots that other contractors wouldn’t touch. We carry Unilock’s OEM edge restraints, joint sand, and matching paver units in our local stock so repairs match the existing field without the wait. Under Clause 1 of the Haven Standard, the price is written before anyone starts. Under the 365-Day Done Right Promise, if it’s not done right, we make it right.

We are Los Gatos service area locals in practice if not in mailing address - Grant spent three straight years running residential and light commercial crews through Willow Glen and the Santa Cruz Mountains foothills, and our trucks are up in the Lexington Reservoir neighborhoods weekly.

Common Unilock Construction Problems We Solve in Los Gatos

• Efflorescence bloom on Umbriano and Brussels Block - Los Gatos hillside fog, especially on lots above Highway 17 near Lexington Reservoir, keeps paver beds damp far longer than the San Jose valley floor just miles east. Soluble salts migrate to the surface and dry into a white mineral haze. We treat with a proprietary efflorescence cleaner, then reseal with a breathable silane-siloxane so moisture can escape without carrying new salts.
• Differential settling and lippage on graded hillside subgrades - The clay soils and seasonal moisture movement on Los Gatos’s sloped lots push the compacted aggregate base out of plane. We’ve lifted and re-screened entire Brussels Block driveway sections where the base had shifted 3/4 inch across a single winter. The paver itself is sound; the base course failed.
• Joint sand washout along the WUI edge - Diablo wind events and defensible-space pressure-washing strip polymeric sand from joints faster here than in flatland Campbell or Santa Clara. We re-sand with Unilock’s OEM polymeric product, then mist-cure it properly so the binder sets before the next Santa Ana-type blow.
• Base erosion on steep driveway aprons - Water sheeting off a sloped Los Gatos lot undercuts the compacted aggregate base and collapses the edge restraint. Up off Highway 17, we tore out a heaved apron that had been undercut by runoff from the graded pad above it, re-compacted the base in lifts, reset Unilock’s OEM edge restraint, and relayed the original pavers with fresh joint sand so the owner kept the color match.
• Retaining wall distress on engineered hillside systems - Unilock Pisa2 and U-Cara walls on Los Gatos’s steep parcels carry surcharge loads from driveways, pools, and graded pads that flatland walls never see. We inspect for bowed courses, failed geogrid layers, and drainage behind the wall face, then repair with the manufacturer’s own corner units, capstones, and drainage aggregate.

Unilock Service in Los Gatos: What Local Conditions Mean for Your Equipment

Here’s the Los Gatos factor that reshapes every Unilock decision we make: because so much of the hillside residential area sits inside California’s Very High Fire Hazard Severity Zone, noncombustible hardscape is now doing double duty as defensible-space fuel break. A paver driveway apron, walkway, or patio border isn’t just circulation - it’s a calculated noncombustible zone between the structure and the wildland interface. This is a design driver you simply don’t see on the flatland side of Campbell or Santa Clara, where Chapter 7A compliance is a checkbox and not a terrain-driven geometry problem.

The Town of Los Gatos Community Development Department adds another layer. Most exterior alterations visible from a public street trigger discretionary design review, not just a standard building permit. A contractor used to pulling straightforward permits in San Jose will find that a Los Gatos Unilock patio replacement or driveway re-grade routinely adds 6-12 weeks and an architectural consistency hearing before a shovel hits the ground. We’ve been through that process enough times to know which plans examiner asks for cross-sections of the base course and which wants to see the paver color against the existing facade. “Measure twice, permit once, then we talk timeline.”

On a separate hillside patio off Blossom Hill Road, we reset Umbriano units that had lipped along the pool edge, re-leveling the sand bed and re-screeding the border course where fog-driven moisture had softened the base. The coastal fog that makes Los Gatos hills pleasant in August is the same fog that keeps substrate moisture elevated year-round.

Unilock Models & Products We Service in Los Gatos

We work with the full Unilock residential line, with particular depth on the units we see most in Los Gatos:

• Brussels Block - the tumbled segmental paver that dominates Los Gatos driveways and walkways. We stock the full color range for repair matching.
• Umbriano - smooth, mottled large-format paver common on hillside patios and pool decks. Efflorescence-prone in fog zones; we carry the manufacturer’s recommended cleaner and sealer.
• Pisa2 and U-Cara - retaining wall systems routinely specified for engineered walls on graded hillside parcels. We source OEM corner units, capstones, and connector pins.
• Copthorne and Town Hall - clay-look pavers frequently chosen for downtown Craftsman and Victorian-era walkways, where the Town’s preservation guidelines favor traditional materials.

When a section is sound, we lift, re-screen, re-base, and relay rather than tear out. Full replacement only when the base course itself has failed or the paver face is spalled past cosmetic repair. We use Unilock’s own OEM edge restraints, joint sand, and matching paver units so color and module match the existing field.

Unilock Service Pricing in Los Gatos

FAQs - Unilock Construction in Los Gatos

Are you an authorized Unilock dealer or installer?

No. We are an independent Unilock service provider - not authorized, sponsored, or warranty-endorsed by Unilock. We tell homeowners that up front because it’s honest, and because our work stands on its own documentation, not a manufacturer’s logo.

Does the coastal fog in the Los Gatos hills cause Unilock pavers to fail?

The fog itself doesn’t damage the paver, but it keeps the substrate damp for extended periods, which accelerates efflorescence bloom on Umbriano and Brussels Block and can soften the sand bed beneath pool-edge courses. We address this with proper drainage design, breathable sealers, and base materials graded for the local moisture regime. Call (669) 271-8644 for an exact quote - estimates are free.

Do you use OEM Unilock parts for repairs?

Yes. We carry Unilock’s own edge restraints, joint sand, and matching paver units in local stock. Color match matters when you’re repairing a 15-year-old Brussels Block driveway and the original lot number is long gone.

How long does a typical Unilock repair take in Los Gatos?

Most single-area repairs - efflorescence treatment, joint sand replacement, or lippage correction on a patio section - finish in one day. Full driveway replacements run 3-5 days plus the Town’s permit timeline, which we handle as part of our scope. We don’t start until the permit is in hand.

Which Unilock models do you cover in Los Gatos?

We service all residential Unilock lines, with the most frequent calls for Brussels Block, Umbriano, Pisa2, U-Cara, Copthorne, and Town Hall. If you have a discontinued series, we can often source matching units through our salvage network or recommend a compatible replacement with a written color comparison.
