Unilock Construction in Los Altos, CA | Framework Contractors
We provide independent Unilock installation and repair across Los Altos, including Loyola Unilock service,, from paver driveways on wide ranch lots to fire-hardened patios near the foothills. The thing that separates our Unilock work here is simple: we build for the city’s 45% lot-coverage cap and its clay-heavy soil, not just for the brochure photo. That changes which pavers you choose and how the base goes in.
Framework Contractors is an independent Unilock service provider, not a manufacturer affiliate or authorized dealer. We install what fits your Los Altos property and your design review constraints. Call (844) 681-3590 for a free estimate, or read on for what Unilock work in Los Altos actually involves.
Why Los Altos Residents Choose Us for Unilock Service
Noel Carbajal grew up helping his uncle patch stucco and reroof porches before he was old enough to drive, and he’s spent nearly three decades since then building and remodeling across California. We apply the same standard to every Unilock paver we set: excavate to spec, compact in lifts, contain the edges. You don’t get that from every crew that shows up with a skid steer.
Los Altos homeowners mostly own 1950s-to-1970s ranch houses on 8,000 to 10,000 square foot lots. Those lots leave room for hardscape, but the city’s planning requirements do not leave room for error. We know what the Los Altos planning counter looks for, which speeds up the back-and-forth when your paver patio or driveway needs design review. One contractor. Every system. Your materials, our craftsmanship. We also offer Unilock service in Mountain View.

Common Unilock Construction Problems We Solve in Los Altos
- Efflorescence on Brussels Block and Beacon Hill after winter rains. Los Altos’ heavy clay soil holds water at the paver base, and when that moisture wicks up through the joints, white mineral bloom follows. We re-grade the base, add drainage, and re-bed the pavers so the moisture moves away instead of up.
- Polymeric sand washout on Eco-Priora permeable pavers. When Eco-Priora is laid over compacted native clay without the specified open-graded base, the joints fill with fines and the sand washes out after a season. We excavate the clay and build the base the way Unilock’s engineering specifies.
- Edge restraint failure on driveways squeezed by setbacks. Los Altos’ 45% lot-coverage cap means driveway bases often get narrowed to fit within the envelope. When the edge restraint can’t hold the lateral load, pavers migrate outward and the driveway starts to bow. We rebuild the edge with deeper restraints and compacted shoulder stone.
- Color fading and surface scaling on U-Cara wall blocks near the foothills. Wildland-urban-interface sun is relentless, and ember exposure strips unprotected wall faces fast. We re-seat or replace scaled blocks and apply the right sealer for the exposure level.
- Paver heaving from clay soil on hillside lots. Loose, expanding clay under a badly prepared base pushes pavers up and out of plane every winter. We see this most on the sloped lots off Springer Road and similar streets in the hills. The fix is excavation and a proper open-graded base, not just re-leveling the surface.
Unilock Service in Los Altos: What Local Conditions Mean for Your Equipment
Here’s the Los Altos-specific fact that changes how Unilock jobs get designed: the city caps lot coverage at 45%, and that cap includes hardscape. A paver patio or driveway counts against your total impervious area. Add too much, and you trigger a variance or a redesign. For Los Altos homeowners, Unilock’s Eco-Priora permeable paver system frequently becomes the only way to add a new patio or expand a driveway without blowing past the limit. Pervious pavers let water infiltrate through the joints and into the ground, so the city’s stormwater calculations treat them differently than solid concrete or standard pavers.
This is not a theory. On a 1960s ranch off Springer Road, we rebuilt a failing Brussels Block driveway where the original base had been laid directly on clay and heaved every winter. We excavated to spec, installed an open-graded base with edge restraint, and re-laid the pavers with fresh polymeric sand. Two seasons later, no movement and no efflorescence. The homeowner said it was the first time the driveway drained instead of puddling at the garage. That’s the difference between building for Los Altos and building somewhere flat with sandy soil and no coverage cap.
Unilock Models & Products We Service in Los Altos
We install and repair the Unilock lines that hold up in Los Altos conditions: Brussels Block, Eco-Priora, Beacon Hill, and U-Cara. Brussels Block and Beacon Hill are our most frequent driveway and patio pavers. Eco-Priora we specify for permeable applications where the coverage cap or drainage needs it. U-Cara wall blocks handle retaining and seat walls, and we treat them differently at the foothills edge where UV and ember exposure run high.
When an existing Unilock surface fails, we diagnose the base before we quote the repair. Re-laying sound pavers over a rebuilt base is often smarter than buying new. When replacement is needed, we source genuine Unilock units for color and dimensional match, paired with high-quality polymeric sand and edge restraints rather than cheap substitutes. We stock common Unilock units regionally for faster Los Altos turnaround. This is what we mean by Unilock sales & service done the way the system is engineered.

AfterUnilock Service Pricing in Los Altos
What you pay depends on the size of the job, access, and what’s under the grass. Los Altos clay soil almost always requires deeper excavation and more base stone than a flatland Peninsula site, which is the single biggest cost driver on paver work here. The numbers below reflect what we see across Los Altos projects:
| Project | Typical Price Range |
|---|---|
| Paver Driveway Installation | $7,000 – $18,000 |
| Paver Patio Installation | $3,500 – $11,000 |
| Home Addition | $45,000 – $130,000 |
Every estimate includes a written line-item quote, base preparation and drainage work, and the specific Unilock product matched to your exposure and coverage constraints. We do not design to the minimum and change-order you later. Built to spec, not to shortcut. Call (844) 681-3590 for exact pricing on your Los Altos property.

FAQs – Unilock Construction in Los Altos
Yes. The city caps lot coverage at 45%, and hardscape counts against that number. If you’re close to the limit, a standard paver patio may push you over, and you’d need a variance or a redesign. That’s exactly why we often specify Unilock’s Eco-Priora permeable pavers for Los Altos patios: the city’s stormwater rules treat pervious surfaces differently, and you can often add the patio without triggering a coverage variance. Call (844) 681-3590 and we’ll run your lot’s numbers before you commit.
That white bloom is efflorescence, and in Los Altos it’s almost always a drainage problem, not a paver defect. Our clay-heavy soil traps moisture at the base, and that moisture wicks up through the pavers, carrying mineral salts that crust on the surface. We fix it by excavating the clay, installing a proper open-graded base, and directing groundwater away from the paver bed. Sealing without fixing the drainage just traps the moisture and makes it worse. Call (844) 681-3590 for a base inspection.
They are, when installed with the right sealer and joint treatment. Concrete pavers don’t burn, which makes them a defensible-space asset. The vulnerability is the surface: U-Cara wall blocks and certain paver faces can scale or fade under prolonged ember exposure and foothill UV. We specify sealers rated for that exposure and schedule re-sealing as part of the maintenance plan. Los Altos hillside properties should not use an unsealed paver face within 30 feet of wildland vegetation.
Usually, yes. When a Los Altos home addition changes the driveway layout or extends a patio, we source genuine Unilock units in the same color, texture, and size. For older Unilock lines that have been discontinued, we can often pull matching units from reclaimed stock or blend a new line into the existing field so the transition reads clean. We’ll always show you the match before we set a single paver. Call (844) 681-3590 and bring a photo of your existing surface.
It raises the base-prep portion of the quote. Clay expands when wet and shrinks when dry, and it drains poorly, so a paver base on untreated clay will heave within a season or two. We excavate deeper than standard practice and bring in an open-graded stone base, sometimes with a geotextile separator, to keep the clay from migrating up into the pavers. That’s labor and material most flatland installs skip, which is why pricing in Los Altos runs higher than in cities with sandier soil. Estimates are free. Call (844) 681-3590.
