Unilock Construction in Los Altos, CA | Milpitas Construction
We install and repair Unilock paver driveways, patios, and retaining walls across Los Altos, including the 94022, 94023, and 94024 ZIP codes. We’re an independent contractor, not a Unilock-authorized dealer, and that independence means we specify Brussels Block, Town Hall, Beacon Hill, and Estate Wall systems because they hold up on Los Altos lots, not because of a badge. If you’re planning a Unilock driveway or patio in Los Altos, call (877) 752-4194 for a free estimate that includes a straight answer about what design review will ask for.
Why Los Altos Residents Choose Us for Unilock Service
Unilock pavers show up on a lot of Los Altos driveways because they handle the wide frontage and mature landscaping this city is known for. We’ve installed Brussels Block and Town Hall fields on those 7,000 to 10,000 square foot lots where a paver driveway has to read clean from the street and hold up to root pressure from 60-year-old oaks. We also offer Unilock service in Stanford for similar estate properties. Ken Stafford grew up in the South Bay and got his construction training at Evergreen Valley College in San Jose, and he’s spent the last two decades working around the soil shifts and entitlement processes that define Silicon Valley residential work. Build it right the first time, the Bay Area doesn’t give you a free pass on shortcuts. That’s the standard we bring to every Unilock job in Los Altos, from a 400-square-foot back patio to a full curb-to-garage driveway replacement.

Common Unilock Construction Problems We Solve in Los Altos
- Efflorescence bloom on Brussels Block and Town Hall. Los Altos gets most of its rain in a short winter window, and that first wet season pulls salts through new pavers and leaves a white haze across the field. We clean it properly and re-seal so the paver color reads the way it should, not chalky and washed out.
- Base settlement and lippage on driveways. The clay subgrade under a lot of Los Altos homes expands and contracts with winter moisture, and tree roots from mature landscaping push up through poorly compacted base. You’ll see individual pavers lift or a low rut form where the car tracks sit. We pull the affected area, correct the sub-base, and re-lay with proper compaction, not just a sand top-up.
- Polymeric sand erosion in permeable joints. Los Altos summers are dry, and the dust, leaf litter, and pollen that settle into paver joints clog the permeable openings. Water stops infiltrating, weeds colonize the joints, and the sand washes out during the first heavy rain. We re-sand with the right polymeric mix and detail the joint profile so it doesn’t just fail again next season.
- Edge restraint failure on wide driveway aprons. Many Los Altos driveways have a long curb-to-garage run, and when the edge restraint spacing is stretched to save material, pavers creep toward the street over time. We install Unilock OEM edge restraints at the manufacturer’s spacing and stake them so the field stays locked.
- Retaining wall movement on grade changes. Los Altos lots aren’t flat, and estate walls built without proper geogrid or drainage behind them start leaning within a few wet seasons. We rebuild with Unilock Estate Wall components and backfill with drainage so the wall does its job through the winter without bowing.
Unilock Service in Los Altos: What Local Conditions Mean for Your Equipment
Los Altos is not a tract-subdivision city. It’s a low-density, discretionary-review jurisdiction where nearly every front-yard change runs through the planning department before you ever move dirt. A Unilock driveway or entry walk addition on a wide, mature-lot street in the Country Club area isn’t just a hardscape swap, it’s part of a larger design-review package. The city will want to see drainage calculations, sightline documentation from the street, and often a shadow or massing study if the project touches a neighbor-visible frontage. We prepare that documentation as part of the bid, because going into a planning hearing without it in Los Altos means a continuance, a revision cycle, and a project that stalls for months. That’s the local reality here, and it’s why our Unilock estimates include the entitlement paperwork, not just the paver count. If you’re outside city limits, we also provide Unilock service in Mountain View with the same thorough approach.
Unilock Models & Products We Service in Los Altos
We work with the Unilock lines that make sense on Los Altos lots: Brussels Block for tumbled, classic driveway and walkway fields; Town Hall for heritage-look patios and entry courts; Beacon Hill for smooth, capped permeable driveways where drainage matters; and Estate Wall for segmental retaining walls and seat walls on sloped yards. When we repair a Unilock installation, we use Unilock’s own edge restraints, polymeric joint sand, and wall-geogrid components so the system stays within the manufacturer’s published detailing. Base aggregate and drainage fittings come from local suppliers to keep cost down without cutting corners on the structural layer. We stock common Unilock components for fast Los Altos turnaround, and we can source any profile we don’t keep on hand within a few days.

AfterUnilock Service Pricing in Los Altos
Unilock paver work in Los Altos is priced by square footage, site access, and how much base correction the existing ground needs. A field on flat, well-drained soil with good truck access costs less than a driveway on a sloped lot with tree roots and a tight side yard. Here’s where our Unilock work typically lands in this market:
| Service | Typical Range |
|---|---|
| Paver Driveway Installation | $7,000 – $18,000 |
| Paver Patio Installation | $3,500 – $11,000 |
| Driveway Replacement | $5,000 – $14,000 |
Every estimate includes the design-review documentation Los Altos will ask for, a written line-item scope, and a fixed price. Call (877) 752-4194 and we’ll walk the site and give you a number that holds.

FAQs – Unilock Construction in Los Altos
Yes, in most cases. Los Altos runs nearly all front-yard hardscape changes through a discretionary design-review process, especially on lots where the driveway is visible from the street or a neighbor’s sightline. We prepare the drainage, sightline, and massing documentation as part of your bid so the planning hearing doesn’t turn into a stall. Call (877) 752-4194 and we’ll tell you what your specific project will trigger before you commit to anything.
Los Altos has short, concentrated winter rains and long, dry summers, so the smart move is to sequence base prep and paver installation into the dry months. Laying pavers into a wet base means compaction problems, joint-sand washout, and a field that settles unevenly before it’s even a year old. We schedule Unilock work for the dry-season window whenever possible, and we’ve built enough Los Altos driveways to know when the weather is about to turn. Nearby homeowners can also request Unilock service in Los Altos Hills with the same weather-aware scheduling.
For driveways, we usually specify Brussels Block or Beacon Hill. Brussels Block gives you the classic tumbled look with the structural density for vehicle loads, and Beacon Hill’s capped permeable profile handles drainage requirements that Los Altos design review often flags. For back patios and entry courts, Town Hall is the go-to because it reads warmer and doesn’t need the same load tolerance. We’ll show you samples and explain the trade-offs before you pick.
It’s normal, not a defect. The white haze is salt migrating through the paver as winter moisture cycles through it, and Los Altos’ wet-then-dry pattern makes the first bloom common on Brussels Block and Town Hall fields. We clean it and re-seal as part of our handoff when it appears, and we’ll tell you how to keep it from returning. If you’re seeing it on a newer install, call (877) 752-4194 and we’ll take a look.
In most cases, yes. Settlement from root pressure or clay movement usually affects a localized area, not the entire field. We pull the affected pavers, correct the sub-base, and re-lay with proper compaction and edge restraint. A full tear-out only makes sense when the base has failed across the whole driveway or the paver color has been discontinued. Call (877) 752-4194 for a repair assessment; estimates are free.
