Oldcastle Driveway & Pavers Nationwide

Oldcastle Driveway & Pavers: The Sunnyvale Owner’s Guide

Oldcastle driveway and paver systems installed in Sunnyvale typically run $7,000-$18,000 for a full paver driveway replacement, with repair of failed sections starting around $1,200-$3,500 depending on base damage. We stock Oldcastle-compatible pavers and base materials, and most Sunnyvale homeowners get a written quote the same day they call. The failure usually shows up as settled areas where the compacted base has washed out, or as individual pavers that rock underfoot because the bedding sand has migrated through a failed edge restraint.

Which Oldcastle Models This Applies To

Oldcastle operates under several product lines in California, and matching the right paver to your existing surface matters for color consistency and structural compatibility. The Oldcastle Coastal series, common in Sunnyvale installations from 2012-2019, uses a 60mm thickness with chamfered edges that differ from the sharper 80mm Commercial line used in heavier-load applications. Check the paver edge for a molded batch code, usually stamped on the vertical face, or measure thickness with a straightedge - mixing 60mm and 80mm pavers in the same field creates a trip hazard within two seasons.

We also see Belgard-branded pavers (Oldcastle’s hardscapes division) in Sunnyvale’s Lakewood Village and Washington Park areas, particularly the Dublin Cobble and Bergerac patterns installed during the 2015-2018 build cycle. OEM Oldcastle pavers are still manufactured, but quality aftermarket equivalents from Techo-Bloc and Belgard’s current line often match closer than aging inventory - we source both and show you the sample side by side before quoting. If your driveway was installed with an Oldcastle permeable paver system, the aggregate base specification differs from standard interlocking concrete pavement, and using conventional bedding sand voids the drainage design.

Signs Your Oldcastle Driveway & Pavers Is Failing

• Sunken or settled sections. Water pooling after rain indicates the compacted aggregate base has washed out or wasn’t installed to the 6-inch minimum depth required in Santa Clara County’s expansive clay soils. The pavers themselves are usually intact; the support beneath them has failed.
• Individual pavers rock or click underfoot. Bedding sand has migrated through a gap, often where edge restraints have pulled away from the perimeter. Left unaddressed, the void spreads and neighboring pavers lose interlock.
• Weeds growing through joints wider than 1/8 inch. Polymeric sand degradation allows seeds to root; in Sunnyvale’s dry summers, this signals the jointing material has broken down and is no longer locking the pavers vertically.
• Edge restraints visible above the paver surface. Plastic or aluminum edging has heaved due to freeze-thaw cycling or inadequate spike depth. In Sunnyvale’s mild climate, this usually means the edging was set with 8-inch spikes in native soil rather than concrete haunching.
• Efflorescence that doesn’t clean off. White mineral deposits migrating from the paver body indicate moisture moving through the unit repeatedly, often from a failed vapor barrier beneath or incorrect slope directing water underneath rather than away.

Replacement Cost & What’s Included

The range depends on three factors: how much base material must be excavated and recompacted (we test with a nuclear density gauge, not visual guesswork), whether the original pavers are still manufactured or require a full-field replacement for color match, and access - tight Sunnyvale lots between neighboring homes add labor hours for material handling. Every quote lists paver cost per square foot, base aggregate delivered and compacted, labor hours, and disposal separately. Under Clause 1 of the Haven Standard, that written price is fixed; no change order, no surprise. Our 365-Day Done Right Promise covers the installation workmanship, and we document the compacted base density with photos you receive before pavers go down.

DIY or Call Us?

Homeowners can safely assess the problem: photograph the settled area, measure the paver thickness with a ruler, and check whether the edge restraint is visible or loose. What you cannot verify without equipment is the compacted density of the aggregate base - visual inspection of “it looks solid” fails regularly, and re-laying pavers on uncompacted base guarantees the same settlement in one rainy season.

Removing and resetting pavers is not dangerous work, but it is precise work. The base must be screeded to 1/4-inch tolerance over 10 feet, the bedding sand graded to prevent washout, and the edge restraint secured with concrete haunching or proper spike depth. We’ve repaired more than a few Sunnyvale DIY resets where the owner spent a weekend and $400 in materials, only to call us six months later when the same section settled again. Measure it twice, write it down, then build it - or call (650) 405-3637 and we’ll quote it in writing before anyone lifts a paver.
