Unilock Construction in Los Gatos, CA | Seaside Contractors
We’re Seaside Contractors, and we install and repair Unilock paver systems across Los Gatos and nearby communities like Monte Sereno, from flat downtown lots to steep 95033 hillside properties. The single biggest factor shaping Unilock work here is water: the atmospheric-river storms that hit the Santa Cruz Mountains concentrate runoff in ways that destroy poorly built bases. If your Unilock driveway, patio, or retaining wall is failing in Los Gatos, call (833) 589-8103 for a free estimate.
Why Los Gatos Residents Choose Us for Unilock Service
Glen Sorrento, our owner, grew up watching lagoon-side homes in Foster City get built and rebuilt, then spent two-plus decades working through nearly every project type the Peninsula throws at a contractor. He’s the guy who can look at a Unilock Brussels Block spec sheet and a hillside drainage plan in the same afternoon and give you a straight answer on both. That matters in Los Gatos, where the terrain punishes shortcuts.
We approach every Unilock installation as a structural project, not a cosmetic one. Base depth, compaction, geogrid reinforcement, drainage routing: these are the unglamorous details that determine whether your pavers stay put through five winters of heavy rain or start shifting after two. Our Unilock sales & service knowledge runs deep enough that we’ll tell you when a repair makes sense and when a full rebuild is the honest answer. We’re an independent provider, not a manufacturer affiliate, so our recommendations don’t come with a sales quota attached.

Common Unilock Construction Problems We Solve in Los Gatos
Here’s what we see repeatedly on Los Gatos properties, and what’s actually causing it:
- Base erosion and settling on sloped sites. In the 95033 hills above Lexington Reservoir, concentrated winter runoff cuts through undersized bases like a knife. We excavate deeper, install proper drainage, and rebuild with a base that can handle the flow.
- Paver heaving from expansive clay soils. The rain-shadowed valley floor around 95032 has clay that swells and contracts through wet-dry cycles. When base depth was minimized to save cost, pavers heave and buckle within a few seasons.
- Efflorescence and surface staining. Los Gatos’s atmospheric-river storms soak paver surfaces repeatedly, and the white chalky residue that follows isn’t a manufacturing defect: it’s mineral salts wicking through the concrete. Proper sealing and drainage planning prevent most of it.
- Edge restraint failure on driveways. Tight turns and steep grades on hillside driveways put enormous lateral pressure on edge restraints. Once the restraint fails, pavers migrate outward and joints widen, creating trip hazards and accelerating base erosion.
- Retaining wall saturation and failure. Unilock Estate Wall systems built without weep holes or gravel backfill trap water behind the wall. On Los Gatos hillsides, that trapped water freezes, expands, and eventually pushes the wall out of plumb.
Unilock Service in Los Gatos: What Local Conditions Mean for Your Equipment
Here’s something you won’t find on a generic Unilock page. The Town of Los Gatos enforces Wildland-Urban Interface building codes for hillside properties, which means Class A fire-resistant construction standards and ember-resistant venting apply to structures in the WUI zone. What does that have to do with pavers? Plenty. A paver patio or driveway isn’t just a surface: it’s part of your defensible space. Gravel and concrete pavers can serve as a fuel break, but the installation method matters. We design Unilock layouts with WUI setbacks in mind, ensuring your hardscape actually helps create usable defensible space rather than adding flammable materials near the structure. That’s the kind of detail a Los Gatos General Contractor understands, while flatland San Jose contractors never touch it because they don’t have to.
Let’s figure out what the job actually needs – then we’ll talk materials.
Unilock Models & Products We Service in Los Gatos
We work with the full Unilock residential lineup, but the models we install most often in Los Gatos are Brussels Block, Beacon Hill, Estate Wall, and Lineo. Brussels Block’s tumbled texture works well for driveways where freeze-thaw cycles demand flexibility. Beacon Hill’s rectangular format suits patios with clean sightlines. Estate Wall handles the retaining demands of hillside terracing. Lineo’s plank format gives a contemporary look that works on modern hillside homes.
On the parts side, we use OEM Unilock pavers for repairs to maintain color and dimensional consistency. Base materials, geotextiles, edge restraints, and drainage components: we source quality aftermarket products that meet or exceed manufacturer specs. The goal is a repair that blends seamlessly and performs better than the original.

AfterUnilock Service Pricing in Los Gatos
Pricing for Unilock work in Los Gatos depends on access, slope, base conditions, and the specific product line. Here are the ranges you should expect for the most common projects:
| Project | Price Range |
|---|---|
| Paver Driveway Installation | $7,000 – $18,000 |
| Paver Patio Installation | $3,500 – $11,000 |
| Home Addition | $45,000 – $130,000 |
Driveways cost more on hillside lots where excavation is deeper and drainage routing is complex. Patios stay more affordable when access is straightforward. A home addition that includes Unilock hardscape integration – outdoor living space, retaining walls, steps – falls into the wider range depending on scope. Every estimate is free and line-itemized. Call (833) 589-8103 for exact numbers on your property.

FAQs – Unilock Construction in Los Gatos
Hillside lots require deeper excavation, geogrid-reinforced bases, and engineered drainage to prevent base erosion and paver migration. On slopes over 5%, we typically excavate 12 to 18 inches, install a geotextile separator, and add channel drains or French drains to route runoff away from the installation. Call (833) 589-8103 for a site-specific assessment.
Brussels Block is our most common choice for hillside driveways because its interlocking shape and textured surface provide traction and structural interlock under load on grades. Lineo works well for a more modern look, but requires precise edge restraint. We’ll spec the right product after evaluating your specific slope and drainage conditions.
Yes, when the base is built correctly. The paver itself is just the surface layer: the base, drainage, and edge restraints do the heavy lifting. We field-tested this on a steep Summit Road lot where we replaced a failing concrete driveway with Unilock Brussels Block, excavating 18 inches for a geogrid-reinforced base and channel drain. Two winters of heavy rain later, no shifting, no ponding, no callbacks. Call (833) 589-8103 to get yours built right.
Driveways and significant retaining walls typically require permits in Los Gatos, especially on hillside properties where geotechnical review may be triggered. Patios at grade often don’t, but if your project includes drainage modifications or WUI-zone compliance work, the Town will want to see plans. We pull permits and schedule inspections on every job where they’re required.
Los Gatos has strict oak tree protection ordinances. We won’t trench within a tree’s dripline without a plan that protects the root zone, and in many cases we’ll adjust the hardscape layout to preserve the tree. Root barriers, permeable base designs, and raised paver systems are all tools we use to build around mature oaks rather than through their roots. Call (833) 589-8103 to discuss your specific trees.
