Unilock Construction in Los Altos, CA | Brookside Contractors
We provide independent Unilock paver and retaining wall installation, repair, and rebuild work across Los Altos through our General Contractor in Los Altos. Our Unilock jobs here are shaped by one thing most contractors miss: the city’s tree-protection ordinance. A heritage oak or redwood and its root-zone setback often dictate the shape, base depth, and edge restraint of a paver driveway or patio before you even get the permit. Call (833) 725-3508 for a free estimate on Unilock work built around your lot, not against it.
Why Los Altos Residents Choose Us for Unilock Service
Nate Burrell, our owner and general contractor, cut his teeth on South Santa Clara County job sites where base compaction and drainage were the difference between a paver field that held for twenty years and one that rutted in three. We know Unilock units the way a mechanic knows a specific engine family – which products tolerate Los Altos’s clay, which ones need geogrid at the edge, and when a repair makes sense versus a full rebuild. We’re an independent contractor, not a Unilock-authorized or manufacturer-affiliated dealer. That means when we tell you a Brussels Block driveway off a tree-canopied Los Altos street is failing because the original base was never compacted to spec, we’re not protecting a brand image. We’re telling you what the soil and the pavers are actually doing. See our full Unilock sales & service capabilities across the South Bay.

Common Unilock Construction Problems We Solve in Los Altos
- Sand-joint washout and rutting on Brussels Block driveways. Dense canopy from mature oaks and redwoods keeps Los Altos pavement shaded and damp long after a winter rain. Water lingers in the joints, the polymeric sand breaks down, and the field starts to wander. We lift, re-base, and relay the affected bay, then seal with fresh polymeric sand that handles the shade and moisture.
- Frost-heave and lateral creep at the edge restraint where the paver field meets a new ADU or second-story addition. Los Altos rarely sees frost, but what homeowners call “heave” here is usually shallow base plus poor edge restraint under new construction weight. When a second-story addition changes the load path, the old paver edge moves outward. We cut back the field, deepen the base, and install a proper curb restraint.
- Efflorescence and algae bloom on Elegance slabs and U-Cara caps. On the shaded north side of older ranch lots in Los Altos, redwood canopies keep surfaces damp for months. White mineral deposits and green algae colonize the paver faces. We clean and re-seal when the surface is sound; when the paver itself is spalled through, we replace the units with genuine Unilock stock.
- Settling and face chipping on U-Cara retaining walls built at the Los Altos Hills WUI edge. Cut slopes along the wildland interface are steeper, and when a wall’s geogrid and drainage aggregate were undersized at original install, the face settles and chips. We rebuild with proper geogrid lifts, drainage gravel, and a perforated drain at the base so the wall doesn’t become a slow-motion failure.
- Narrow-band paver failures pushed against protected root zones. When an arborist report restricts paving to a narrow band between a heritage oak and a property line, the paver field gets narrow and the base detail has to work harder. We see edge failures and joint pumping in these tight strips because the original installer treated it like a normal patio. It isn’t.
Unilock Service in Los Altos: What Local Conditions Mean for Your Paver Work
Los Altos requires an arborist report and root-zone setbacks before a hardscape permit is issued. That sounds bureaucratic until you live it: a mature heritage oak or redwood in the rear yard frequently dictates exactly where a paver patio or driveway apron can sit. On Old Los Altos lots this often pushes the paver field into a narrow band rather than a clean rectangle. Your base detail and edge restraint now have to be designed around a protected root zone, not the clean geometry on the original landscape plan. We build the paver field to work within that constraint. On a North Los Altos lot off a tree-lined street, we rebuilt a rutted Brussels Block driveway where the arborist’s root-zone line cut across the planned apron. We lifted the pavers, re-excavated to proper depth outside the protected zone, installed geogrid and a curb restraint, and relayed the field with fresh polymeric sand, keeping the protected root area unpaved. Do it once, do it right – everything else is just a future repair bill. This is the Unilock work that separates us from a flatland contractor who’s never had to argue with an arborist.

Unilock Models & Products We Service in Los Altos
We work with the Unilock lines Los Altos homeowners actually install: Brussels Block for classic tumbled driveways, U-Cara Wall System for segmental retaining walls with interchangeable face panels, Elegance for larger-format patio slabs, and Beacon Hill Flagstone for textured walkways. For repairs we source genuine Unilock units and matching edge restraints so a patch blends with the existing field rather than showing a mismatched seam. We stock our shop van with the common Los Altos-spec base aggregate, polymeric joint sand, and geogrid so a small repair doesn’t wait on a parts run. When a paver field fails only in one bay, we lift, re-base, and relay. When the base or wall structure is compromised, we tell owners to rebuild rather than patch. We don’t sell aftermarket units as “just as good” – we’ve pulled enough cheap Chinese pavers out of Los Altos driveways to know better.

AfterUnilock Service Pricing in Los Altos
What drives the cost on Unilock work here is access, root-zone constraints, and whether the existing base is salvageable. A clean paver patio on an open lot is a different job than a Brussels Block driveway that threads between two protected oaks and a WUI setback. Here’s the range for the Unilock services we most often handle in Los Altos:
| Unilock Service | Typical Los Altos Price Range |
|---|---|
| Paver Driveway Installation | $7,000 – $18,000 |
| Paver Patio Installation | $3,500 – $11,000 |
| Driveway Replacement | $5,000 – $14,000 |
| Driveway Sealing | $250 – $700 |
Every job gets a written line-item quote after we walk the site and read the arborist report if one applies. No change orders for base depth we should’ve caught on day one. Call (833) 725-3508 for an exact estimate on your Unilock project in Los Altos.

FAQs – Unilock Construction in Los Altos
Yes. We source genuine Unilock units from the same product line you already have and match the joint sand and edge restraint so the repair blends correctly. The trick is knowing which lot your pavers came from and whether the color has weathered, which is exactly the kind of detail that separates a clean patch from a visible scar. Call (833) 725-3508 and we’ll tell you what’s possible for your specific paver line.
No. Brookside Contractors is an independent general contractor. We buy genuine Unilock units direct and install them to manufacturer spec, but we do not claim Unilock authorization, partnership, or warranty endorsement. We like it that way. It means our advice on whether to repair or rebuild is based on your paver field’s condition, not on a dealer agreement.
A single-bay lift and re-lay on a Brussels Block driveway usually takes two to three days on site. A full driveway rebuild or U-Cara wall reconstruction runs one to three weeks depending on access, root-zone constraints, and weather, and we also provide Unilock service in Mountain View for similar projects. Los Altos’s dry summers mean we can schedule hardscape work nearly year-round, which most of our clients appreciate. Call (833) 725-3508 and we’ll give you a realistic timeline, not a sales pitch.
We service Brussels Block, U-Cara Wall System, Elegance, and Beacon Hill Flagstone lines, including adjacent edge restraints and caps. If you have an older Unilock line that’s still in the field, we’ll assess it in person and tell you honestly whether matching units are still available or whether a complementary replacement is the better move.
Rutted driveway repairs that require lifting, re-basing, and relaying a bay of pavers typically fall between $2,500 and $6,000 depending on square footage and whether the edge restraint needs replacement. Full driveway replacement with Unilock units runs $5,000 to $14,000 in Los Altos. The difference between patch and rebuild comes down to what we find under the pavers once we lift them. Call (833) 725-3508 for an exact quote – estimates are free.
