Unilock Construction in Portola Valley, CA | Viceroy Construction
Viceroy Construction installs and repairs Unilock pavers and walls across Portola Valley, offering independent service with no dealership markup and no warranty-agent delays. What makes our Unilock work different here comes down to one thing: we build every paver project to satisfy Portola Valley’s WUI defensible-space code, not just to look good in a brochure photo. That means noncombustible hardscape within five feet of the house, compacted base work that won’t heave on clay, and edge restraints that meet ignition-resistant detailing. Call (877) 358-6557 to talk with Neil Drummond about your project scope.
Why Portola Valley Residents Choose Us for Unilock Service
Plenty of hardscape crews can lay pavers. Far fewer understand how Unilock systems behave on Portola Valley’s sloped, wooded lots with clay soil and winter rain cycles. Neil Drummond grew up in the Saratoga foothills and trained in the building trades program at West Valley College, where framing, concrete, and structural coursework gave him a foundation in what actually holds up over time, including Stanford Unilock service work. His father was a finish carpenter who never cut corners, and that particular lesson stuck. The details you don’t see are the ones that matter most.
Our crews work with Unilock product lines every season, so we know which pavers show salt bloom in Portola Valley’s wet winters and which wall blocks hold up through red-flag summer heat. We’re an independent contractor, not a manufacturer affiliate, which means we recommend the right Unilock product for the site rather than pushing whatever’s in stock at a distributor. And because we’re a full-scope general contractor, the same team handling your paver patio can also manage the adjacent retaining wall, drainage, or landscape lighting without handing you off to a sub you’ve never met. See our full Unilock sales & service coverage for more on our approach.

Common Unilock Construction Problems We Solve in Portola Valley
- Efflorescence and salt bloom on Brussels Block pavers. Portola Valley’s clay soils hold moisture through winter, then dry hard in summer. That seasonal wetting and drying pulls mineral salts up through the paver face, leaving white, powdery deposits that are ugly and stubborn. We clean and reseal, and we adjust the base and bedding layer so the cycle stops recurring.
- Paver heaving and settlement from inadequate base compaction. Older Portola Valley estates often have driveways and patios that were laid on whatever fill was handy decades ago. On a sloped lot, that unengineered base shifts with the first heavy rain, and you get sunken sections, lippage, or pavers that rock underfoot. We tear out, grade, compact, and rebuild with a proper aggregate base and geotextile separation.
- Estate Wall block cracking or leaning from hydrostatic pressure. When drainage behind an Estate Wall is compromised, Portola Valley’s winter rains build up water pressure that the wall was never designed to hold. Blocks crack, the wall leans, and the top course starts drifting. We rebuild the wall with proper drainage aggregate, weep holes, and geogrid where the site demands it.
- Surface spalling and color fade on Beacon Hill pavers. South-facing patios in Portola Valley take intense UV all summer, plus abrasive wildfire ash in the fall. The surface gradually erodes and the color goes chalky. We can resurface and seal, or replace individual units to restore the original look without a full tear-out.
- WUI code violations on older hardscape. Homes built before the current Chapter 7A ignition-resistant standards often have wood chips, bark mulch, or combustible decking within five feet of the structure. Swapping those zones to Unilock concrete pavers brings the property into compliance while improving the look. We know what the town’s reviewers flag, because we’ve been through their checklists.
Unilock Service in Portola Valley: What Local Conditions Mean for Your Equipment
Portola Valley’s WUI code is strict enough that even a paver patio replacement can trigger a full defensible-space review, and the town’s architectural review of every new build often adds months to the project timeline. But the code also creates an opportunity: noncombustible hardscaping within the first five feet of a structure is specifically allowed and often encouraged, which means Unilock concrete pavers and walls are not just an aesthetic choice here. They’re a defensible-space component. That changes how the work has to be done. Base prep and edge restraints must meet ignition-resistant detailing, not just drainage standards, and the paver selection has to work with the fire-resistant cladding and roofing choices the town’s reviewers already approved. On a Westridge Drive estate near Unilock service in West Menlo Park, our crew tore out a heaved Brussels Block driveway that had been laid on insufficient base and reinstalled it with a compacted aggregate base, geotextile separation, and new edge restraints to meet the town’s WUI defensible-space requirements. We matched the existing Brussels Block color and replaced the failing Estate Wall segment with proper drainage. The homeowner now has a stable, fire-resistant hardscape that also improves driveway access for emergency vehicles. This is the work generic hardscape pages don’t tell you about, because they were never written for Portola Valley’s specific code environment.
Unilock Models & Products We Service in Portola Valley
We install and repair the Unilock lines most common on Portola Valley properties: Brussels Block for driveways and walkways where that tumbled, old-world look fits the rural estate character; Beacon Hill for patios where a more formal, large-format paver reads clean against modern rebuilds; Estate Wall for retaining and freestanding walls on sloped lots; and Lineo for contemporary hardscape designs that suit the newer fire-resistant builds going up around town. For replacements we source genuine Unilock pavers and wall blocks so color and texture match the existing surface. For base materials, bedding sand, and polymeric joint stabilizer, we use quality aftermarket products that outperform OEM equivalents in Portola Valley’s specific soil and drainage conditions. We stock common repair materials locally, which speeds up smaller jobs without shipping delays.

FAQs – Unilock Construction in Portola Valley
Yes, in most cases any exterior work within the defensible-space zone can trigger a WUI compliance review, and if your project involves new hardscape adjacent to a structure, the town will look at it through that lens. We handle the paperwork and detail the installation to pass review the first time. Call (877) 358-6557 and we’ll tell you exactly what your property triggers before we quote.
Yes. We source genuine Unilock Brussels Block pavers in the same color blend as your existing surface, and we’re realistic about aging: a brand-new paver next to a 15-year-old one won’t be invisible. Where it matters, we’ll blend by pulling pavers from a less visible area and feathering in the new stock. Call us if you’ve got a section that’s failing and want an honest assessment of whether to patch or rebuild.
That’s efflorescence: mineral salts carried up through the paver by moisture that’s wicking from the clay soil and the bedding layer. Portola Valley’s wet-winter, dry-summer cycle makes it especially common here. We clean it, seal the surface, and address the base and drainage so the moisture path that caused it stops repeating. Call (877) 358-6557 and we’ll come look at it.
Portola Valley and Unilock in Los Altos Hills reviews nearly every exterior improvement, and a hardscape project can sit in that queue for weeks or months depending on scope and current workload. We prepare submittals with the WUI and defensible-space details the reviewers care about, which is usually the difference between an approval and a resubmittal. That preparation shortens the review, but we can’t make the town move faster. We’ll give you a realistic timeline before you commit.
A minimum of 6 – 8 inches of compacted aggregate over geotextile fabric on native soil, with additional depth and possibly geogrid on slopes over 5% or where the existing fill is suspect. Edge restraints have to be pinned into the base, not just staked into dirt, or the pavers will creep downhill with the first heavy rain. On Portola Valley clay, we typically over-excavate and import better drainage aggregate. Call for an exact scope: (877) 358-6557.
