Unilock Construction in Los Gatos, CA | Millwright Builders
We install, repair, and rebuild Unilock paver driveways, patios, and walls across Los Gatos, from downtown 95030 up into the hillside zones of 95032 and 95033, and we also provide Unilock service in Monte Sereno. The thing that separates our Unilock work here from flatland crews is simple: we build for expansive clay soils and WUI Chapter 7A fire code, because both shape every hillside project in Los Gatos. Call (866) 925-0334 for a free estimate on Unilock construction, repair, or full replacement.
Why Los Gatos Residents Choose Us for Unilock Service
Noel Castañeda spent two decades doing residential work across the Peninsula before founding Millwright Builders, and he’s seen what happens when paver crews treat Los Gatos like any other Bay Area suburb. It doesn’t end well. Slopes move. Clay swells. Winter storms wash out bases that were never engineered for this terrain. We carry that experience into every Unilock job we take.
We’re an independent hardscape contractor, not a Unilock dealer and not manufacturer-affiliated. That independence matters because it means we spec what actually performs on your site rather than what a brand catalog pushes. We install Unilock pavers and walls because they’re good products. We also know their failure modes well enough to repair them properly when Los Gatos conditions do their worst. Build it right the first time – the Peninsula weather will find out if you didn’t.

Common Unilock Construction Problems We Solve in Los Gatos
These are the calls we get most often from Los Gatos homeowners:
- Efflorescence and salt bloom on Brussels Block. The expansive clay under Los Gatos hillsides holds moisture and wicks it upward through the paver. What looks like white staining is mineral salts being pulled to the surface. We clean it properly and address the drainage that feeds it.
- Settlement and heaving on sloped driveways. When a base wasn’t compacted for Los Gatos clay, the dry-wet cycle of summer drought and winter atmospheric rivers shifts the subgrade. Pavers sink, lift, or separate. We rebuild with proper base depth and compaction for the actual soil you have.
- Edge restraint failure on hillside installations. Seasonal soil movement and runoff push against paver edges. If the restraint wasn’t anchored properly, you get spreading and gaps along the edges. We repair or rebuild with edge systems that actually hold.
- Permeable paver clogging with clay fines. Eco-Priora pavers are excellent for managing stormwater, but after a few atmospheric-river winters in Los Gatos, the joint aggregate can clog with fine clay particles. We restore infiltration capacity without replacing the whole surface.
- Base washout after storm events. On steeper Los Gatos lots, concentrated runoff can erode the base from under a paver driveway or patio, even when the surface looks intact. We identify the drainage failure and fix it so the base doesn’t disappear twice.
Unilock Service in Los Gatos: What Local Conditions Mean for Your Equipment
Here’s what most paver crews miss in Los Gatos. The hillside zones in 95032 and 95033 fall under WUI Chapter 7A, which means even hardscape elements like paver walkways, patio edges, and retaining walls have to meet ignition-resistant construction details. That’s a fire-code requirement on top of the geotechnical concerns around expansive clay and slope stability. A flatland crew that’s never pulled a permit in the Santa Cruz Mountains foothills won’t know to check it. We do.
On a steep driveway off Blossom Hill Road in 95032, we tore out a heaved Unilock Brussels Block driveway where the original base had been washed out by winter storms — a problem we also address with our Lexington Hills Unilock service. We rebuilt with geogrid and a permeable Eco-Priora border to manage runoff, and the homeowner now has a stable, WUI-compliant surface that sheds water instead of trapping it. That’s the difference between installing pavers and engineering them for Los Gatos.

FAQs – Unilock Construction in Los Gatos
Yes, but only with proper base engineering. Expansive clay expands and contracts with moisture changes, which transfers movement to the paver surface above. We over-excavate the clay, install geotextile fabric, and build a compacted aggregate base deep enough to isolate the pavers from soil movement. On slopes, we add geogrid. Skip these steps and you’ll get cracking and heaving within a few seasons. Call (866) 925-0334 if you want to know what your specific lot requires.
Unilock concrete pavers themselves are non-combustible, but Chapter 7A compliance goes beyond the paver material. The base, edge details, and surrounding landscape all factor into ignition resistance. We build hardscape details that satisfy Los Gatos hillside fire code, including non-combustible zones at structure edges and proper joint materials. If your project is in the WUI, this gets handled in the plans, not skipped at installation.
That white staining is efflorescence, mineral salts migrating up through the paver from moisture in the subgrade. In Los Gatos, expansive clay holds water and feeds the process. Cleaning the surface alone won’t fix it – you need drainage correction so water isn’t sitting under the pavers. We diagnose the moisture source and repair it, then clean the surface so the stains don’t return every winter.
In Los Gatos, a Unilock paver driveway typically runs $7,000 to $18,000 depending on square footage, slope, soil conditions, and whether we’re starting from bare ground or removing an existing surface. Hillside jobs with retaining walls or drainage work fall at the upper end or beyond. Call (866) 925-0334 for an exact quote – estimates are free.
In most cases, yes. If the base is stable and only specific areas have settled, we lift the affected pavers, re-level and re-compact the base, and relaid them. If the settlement traces back to a failing base or a drainage problem, a partial repair won’t last – and we’ll tell you that upfront. We recommend repair over replacement whenever the base is sound.
