Belgard Construction in Hillsborough, CA | Ashford Contractors
We provide independent Belgard hardscape construction and repair across Hillsborough, and our work here is shaped by the one condition most paver crews miss: clay-heavy hillsides that hold winter moisture against the base. If your paver driveway or patio is settling, heaving, or creeping at the edges, we fix it at the base and drainage level, not with cosmetic patching. Call Ashford Contractors at (877) 752-3868 for Belgard construction in Hillsborough, from new driveway and patio installs to structural repair of existing hardscape.
Why Hillsborough Residents Choose Us for Belgard Service
Hillsborough isn’t a tract-home market. Nearly every project we take on here sits on a sloped, tree-covered estate lot where the hardscape has to survive clay soil, winter runoff, and root-zone pressure from mature oaks and redwoods. Most Belgard paver failures we see in Hillsborough trace back to two things: a base that was never graded to drain, and edge restraint that wasn’t built for the grade. We approach every Belgard installation here with those two factors as the starting point, not an afterthought.
Glen Mossier, who leads Ashford Contractors, trained in construction technology at Skyline College and has spent two decades building on Peninsula soils. He grew up watching Foster City lagoon-side homes get rebuilt after water intrusion, and he carries the same approach into Hillsborough: fix the drainage and base first, and the surface lasts. We’re an independent Belgard service provider, which means we’re not tied to any manufacturer’s warranty program. We’re also a Hillsborough General Contractor, so when a paver project opens up a retaining wall issue, a drainage problem at the foundation line, or an opportunity to tie the hardscape into a home addition, we handle it in-house rather than handing you off to three different crews.

Common Belgard Construction Problems We Solve in Hillsborough
- Edge creep and paver dropout on sloped driveways. Hillsborough driveways frequently run at 10 to 15 percent grade or steeper. When the edge restraint is undersized or the polymeric sand was installed over a base that doesn’t drain, the outside courses start walking downhill within a few wet seasons. We reset the edge, re-grade where necessary, and restore the restraint system before the pattern fails entirely.
- Efflorescence and salt bloom on paver surfaces. Hillsborough’s clay-heavy soil holds water against the base well into spring. When that moisture wicks up through a shallow base, you get white mineral deposits on Belgard pavers that keep coming back after surface cleaning. The fix isn’t scrubbing; it’s deeper aggregate, better subdrainage, and a correct base depth so moisture never reaches the wear layer.
- Retaining wall block cracking and rotation. We see Belgard wall systems fail behind the block when clay backfill isn’t drained and hydrostatic pressure builds during winter rains. A wall that looked fine in October can lean by February. We excavate, install proper drainage behind the wall, and rebuild with the original Belgard units where they’re intact.
- Tree-root heave cracking paver fields. On wooded Hillsborough lots, roots from mature oaks and eucalyptus extend far beyond the trunk. When the base is compacted too thin around protected root zones, the pavers lift and crack within a few years. We build root-zone-aware bases that hold their grade without damaging the tree, and we coordinate with the arborist when the project requires it.
- Settling at the lower apron of sloped driveways. This is the classic Hillsborough failure. Water collects at the bottom of the slope, seeps into the base, and the apron sinks. Patching the low spot without fixing drainage just moves the problem a few feet over. We re-grade, add a subdrain where the slope demands it, and reset the apron so water never pools under the pavers.
Belgard Service in Hillsborough: What Local Conditions Mean for Your Equipment
Hillsborough’s large, wooded estate lots mean a Belgard paver driveway or patio is almost always installed within an active tree-protection zone. Root-zone limits and architectural review of the hardscape footprint can decide the layout before we set a single base course. That’s a constraint that rarely appears on flatter San Mateo or Burlingame lots, where the main concern is usually just square footage and curb appeal. Here, the town’s design review can restrict how close pavers may run to a heritage oak, and a tree-protection fence may shrink the buildable area by ten or fifteen feet from the original design. We’ve built Belgard driveways and patios on Hillsborough lots where the final layout was 20 percent smaller than the first sketch, entirely because of root-zone setbacks. A contractor who doesn’t do Hillsborough work regularly learns this the day permits get flagged. We plan for it before the first base course is ever ordered.
On a sloped wooded lot off Eucalyptus Avenue in Hillsborough, we rebuilt a Belgard Dimensions driveway that kept heaving at the lower apron each winter. The original base drained straight into clay and the edge restraint had crept. We pulled the failed course, re-graded the base with a proper subdrain and thicker compacted aggregate, reset the Belgard pavers with fresh edge restraint and polymeric joint sand. The apron has stayed level through two wet seasons since. That’s the kind of fix you only get when someone looks at the ground under the pavers, not just the pavers themselves.
Belgard Models & Products We Service in Hillsborough
We install and repair the full range of Belgard hardscape systems in Hillsborough: Belgard Dimensions pavers for large-format driveways and modern estate patios, Belgard Catalina granite pavers where a natural stone look fits the home’s architecture, Belgard Urbana stone wall blocks for retaining walls and garden terracing, and Belgard Holland Stone pavers for traditional patterns that work well on period Hillsborough homes. When we repair an existing Belgard field, we source matching Belgard units and use compatible OEM edge restraints and polymeric joint sand for structural continuity. We don’t patch Belgard with mismatched generic concrete pavers. On a sound field, we repair and re-sand. When base failure or widespread settling makes patching a losing cycle, we say so and recommend full replacement.

AfterBelgard Service Pricing in Hillsborough
Hillsborough Belgard work prices on three things: the size of the paver field, the amount of base and drainage work the slope demands, and whether tree protection or design review adds engineering time. Here are the ranges we work within for Belgard construction in Hillsborough:
| Service | Price Range |
|---|---|
| Paver Driveway Installation | $7,000 – $18,000 |
| Paver Patio Installation | $3,500 – $11,000 |
| Home Addition | $45,000 – $130,000 |
What drives a Hillsborough paver project higher within those ranges is typically the base. A flat lot with sandy soil needs less aggregate and less drainage than a sloped clay lot with decades of root activity beneath it. Our free estimates include a site visit, base assessment, and a written line-item quote so you know exactly what the grade and drainage on your lot will require. Call (877) 752-3868 to schedule yours.

FAQs – Belgard Construction in Hillsborough
Yes, with a properly engineered base and drainage. We’ve installed Belgard Dimensions and Holland Stone driveways on grades up to 15 percent in Hillsborough, but the base matters more than the paver. A sloped driveway on clay soil needs deeper compacted aggregate, a subdrain at the low point, and a reinforced edge restraint. Skip any one of those and the driveway starts creeping. Call (877) 752-3868 and we’ll assess your grade before any work is quoted.
That white haze is efflorescence, and on Hillsborough clay soil it’s almost always a moisture problem under the pavers, not a defect in the Belgard units. When groundwater wicks up through a shallow or poorly drained base, it carries minerals that crystallize on the surface. Cleaning the surface without fixing the base means the haze returns. We correct the drainage and base, then clean and re-sand the field. For an exact diagnosis, call (877) 752-3868.
In most cases, yes. Hillsborough requires architectural review for new hardscape, and if your lot has protected trees, you may also need arborist sign-off and a tree-protection plan before excavation begins. We handle the paperwork as part of the project, including the site plan showing the Belgard paver footprint relative to root zones and property line setbacks. Call (877) 752-3868 and we’ll walk you through what your specific lot will trigger.
We work within the tree-protection zone, which usually means hand-digging near critical root areas, installing root-barrier fabric where the wall crosses root zones, and building drainage that doesn’t saturate the remaining root plate. Hillsborough’s review process sets the exact limits, and we build to those limits rather than pushing them. If the wall conflicts with a protected tree, we’ll tell you before we dig, and we’ll work with your arborist on an alternative. Call (877) 752-3868 to talk through your lot.
For a Hillsborough home addition or ADU, Belgard makes sense when the patio or walkway needs to tie visually into the existing hardscape and survive sloped clay conditions. We’re a full-scope general contractor, so we can run the Belgard patio, the addition’s foundation drainage, and the ADU layout as one coordinated scope rather than three separate trades. The paver patio typically runs $3,500 to $11,000 depending on size and base work. Call (877) 752-3868 for a combined estimate on the hardscape plus the addition.
