Unilock Construction in Los Altos Hills, CA | Framework Contractors
Unilock paver and wall work in Los Altos Hills succeeds or fails on grading, drainage, and access. As a Los Altos Hills General Contractor, Framework Contractors installs and repairs Unilock Brussels Block, Cambridge, and Brussels Dimensional systems independently, which means our recommendations come from building on these specific hillside parcels, not from a manufacturer script. Call (844) 681-3590 for a free Unilock estimate anywhere in the 94022 zip code.
We’ve rebuilt enough settled patios and shifted walls in Los Altos Hills to know that the paver itself is rarely the problem. The sub-base, the drainage plan, and the way the site was graded are what determine whether a Unilock hardscape holds for five years or twenty-five. That’s the experience we bring to every job, from Unilock sales & service through full installation and repair.
Why Los Altos Hills Residents Choose Us for Unilock Service
Unilock makes a genuinely good product. Brussels Block and Cambridge pavers with ArmorTec hold color and surface texture better than most alternatives, and the Brussels Dimensional System wall units lock together cleanly when built correctly. But a Unilock system performs only as well as the base beneath it and the drainage routed around it. On Los Altos Hills lots with 20 to 40 percent slopes, seasonal creeks, and clay-to-shale subsoils, that base work is everything.
Noel Carbajal, our owner, started building and remodeling in hilly terrain almost three decades ago. He learned early that water moves downhill and it will find the easiest path, often directly under a freshly laid paver patio. Since then, we’ve made drainage and base stabilization the first questions we ask on every Los Altos Hills Unilock project, not an afterthought. We’re Los Altos Hills service area regulars, and we know what these parcels demand.

Common Unilock Construction Problems We Solve in Los Altos Hills
- Efflorescence and salt bloom on Brussels Block and Cambridge pavers. Los Altos Hills sits against the Santa Cruz Mountains foothills. When sub-base drainage fails on a slope, water sits under the unit layer and wicks minerals to the surface, leaving a chalky white film. We fix the drainage first, then address the surface. Replacing pavers without fixing the water path means the bloom returns in a season.
- Base settlement and paver heaving on steep grades. Hilliside patios built for a view often get built with shallow excavation and no geogrid. Two wet winters later the field is uneven and trip-hazardous. We pull the units, cut the grade properly, install a stabilized base with geogrid where the slope calls for it, and re-lay the field level.
- Chipping and edge spalling at driveway aprons and turning radii. On tight hillside driveways off private lanes, delivery trucks and concrete mixers track right over the edge restraints. Cambridge pavers at the apron take the abuse. We replace spalled units and re-set edge restraints with the proper restraint system so the damage doesn’t spread inward.
- Retaining wall movement in Brussels Dimensional System or Copthorne units. Walls built without geogrid tie-back into the slope, especially above seasonal creek drainages, start to lean or bow within a few winters. We rebuild the wall with proper tie-back, drainage gravel, and positive drainage behind the face, using genuine Unilock units and caps.
- Standing water and ponding on paver patios. A patio built without a positive fall away from the house ends up holding water where the soil meets the foundation. On Los Altos Hills lots with clay-heavy subsoil, that water doesn’t drain. We re-grade and re-lay the field so stormwater moves off the surface and away from the structure.
Unilock Service in Los Altos Hills: What Local Conditions Mean for Your Equipment
Here’s something specific to Los Altos Hills that stock Unilock pages never mention: projects on the narrow private lanes off Arastradero, Page Mill, and Moody often can’t get a delivery truck turned around. Unilock pallets get dropped at the lane mouth and walked in by machine or hand. That changes how we stage base material, sand, and units. It means a job that takes two days on a flat Palo Alto lot can take four here. We factor that reality into our schedules and our bids from the start. The town’s lot-coverage and planning-review rules also mean hardscape gets drawn and approved alongside the house, so paver layouts need to be settled before earthwork starts. We’ve learned to work with the planning timelines rather than against them, and we recommend clients in Los Altos Hills settle hardscape decisions early in the design process. We also offer Unilock repair in Los Altos for nearby properties with similar hillside challenges. On a steep wooded parcel off Page Mill, we rebuilt a settled Brussels Block patio behind a mid-century ranch that had heaved where runoff from the slope above pooled under the base. We pulled the units, re-cut the grade to a positive fall away from the house, added a stabilized base with drainage and edge restraint, and re-laid the salvaged and replacement pavers. The patio now sheds stormwater instead of trapping it.
Unilock Models & Products We Service in Los Altos Hills
We work with the full Unilock residential hardscape line: Brussels Block in all standard and tumbled finishes, Cambridge Pavingstones with ArmorTec in plank and standard formats, the Brussels Dimensional System for walls and steps, and Copthorne and Town Hall wall units for accent walls and seat walls. When we repair a field, we use genuine Unilock units and matching edge restraints, caps, and polymeric joint sand so color and dimensional tolerances stay consistent across the entire surface. Where a wall face or paver field has settled or spalled, we rebuild the base and replace affected units rather than patch over a failing sub-base. For Los Altos Hills clients, we keep the most common Brussels Block and Cambridge units readily orderable and can typically have material on site within a week of estimate approval.

AfterUnilock Service Pricing in Los Altos Hills
Every bid depends on access, slope, and what’s underneath the existing surface. On a flat lot with easy access, a paver patio runs on the lower end. On a steep parcel with lane-walked pallets and saturated clay, it trends higher. Here’s what you can expect in Los Altos Hills:
| Service | Price Range |
|---|---|
| Paver Driveway Installation | $7,000 – $18,000 |
| Paver Patio Installation | $3,500 – $11,000 |
| Home Addition | $45,000 – $130,000 |

FAQs – Unilock Construction in Los Altos Hills
Yes, when the base is built for it. A properly compacted base with geogrid reinforcement and a restrained edge will hold up to the grades we see on Los Altos Hills lanes. The paver itself isn’t the limiting factor; excavation depth and compaction are. Call (844) 681-3590 for a site evaluation.
The chalky look is efflorescence from water sitting under the paver layer and wicking minerals up through the units. The holding water is a separate grading problem. Both share the same root cause: sub-surface drainage. We fix the drainage path first, then address the surface. Call (844) 681-3590 and we’ll diagnose what’s happening under your patio.
Yes. Los Altos Hills caps home size relative to lot area and requires planning and architecture review for new construction. Hardscape typically gets drawn and approved alongside the house, so paver layouts need to be settled before earthwork starts. We’ve worked through enough Los Altos Hills planning reviews to know where the friction points are and how to avoid them. Our Unilock repair in Loyola covers similar planning requirements in that nearby community.
We have them dropped at the lane mouth and walk them in by machine or hand. It’s slower and costs more in labor, and we budget for it from the first bid. We won’t surprise you with a staging fee mid-project.
Built correctly, yes. The key is geogrid tie-back into the slope, proper drainage gravel behind the wall face, and a solid leveling pad. Build a Unilock wall without those on a Los Altos Hills hillside and it will move. Build it correctly and it’ll hold for decades. Call (844) 681-3590 for an exact quote on your wall project.
