AfterES Windows Driveway & Pavers: The Sunnyvale Owner’s Guide
We stock and install ES Windows-compatible driveway and paver systems in Sunnyvale, with typical installed pricing from $7,000 for paver driveway work and $3,500 for paver patio installations. Most ES Windows paver projects we see involve matching existing hardscape profiles where the original installation has settled, cracked, or lost edge restraint. You’ll usually notice the failure first as a wobble underfoot near the garage threshold, or a visible gap where the paver field meets the concrete foundation pad - both signs that the bedding layer or edge restraint has degraded.
Which ES Windows Models This Applies To
ES Windows, based in Miami, manufactures impact-rated windows and doors; their hardscape division produces paver systems sold through regional distributors in California, including the ES Windows StoneGate and TerraPave lines most common in Sunnyvale installations from 2012 to 2020. To identify your exact profile, check the spacer tabs on the paver edge - StoneGate uses a 3/16-inch beveled tab, TerraPave a flat 1/4-inch tab - or look for the stamped lot number on the pallet wrap if you have leftover material.
We are an independent service provider, not affiliated with ES Windows. For OEM matching, we source through ES Windows’ West Coast distribution in Ontario, California, with a 5-7 business day lead time. For faster turnaround, we stock Belgard and Techo-Bloc equivalents in our Sunnyvale warehouse that match the 60mm and 80mm thicknesses ES Windows specifies, and we’ll show you both options on the written quote - OEM part number, aftermarket equivalent, and the price difference - so you decide before we order. The compatibility gotcha: ES Windows’ early TerraPave runs (pre-2016) used a proprietary chamfer angle that doesn’t seat cleanly with standard ICPI-compliant edge restraints. We measure it on site before quoting.
Signs Your ES Windows Driveway & Pavers Is Failing
- Sunken or tilted pavers near the garage slab. The bedding sand has washed out or compacted unevenly, often from irrigation overspray against the foundation - a pattern we see repeatedly in Sunnyvale’s older Lakewood Village homes where the original screed layer was too thin.
- Gaps opening between paver rows. The joint sand has degraded and the edge restraint - plastic, concrete, or aluminum - has pulled away from the perimeter, letting the field spread. In CA’s dry summers followed by winter saturation, this cycle accelerates.
- White efflorescence haze on the surface. Soluble salts migrating through the paver body, usually from hard water contact or deicing residue. It’s cosmetic but signals porous paver degradation that will worsen with freeze-thaw if left untreated.
- Cracked pavers in the wheel path. The base layer (typically Class II aggregate, 4-6 inches) has insufficient depth or was inadequately compacted; the paver itself is the symptom, not the cause, and spot replacement without base repair fails within two seasons.
- Pooling water that didn’t used to collect. The original slope, spec’d at 1/8 inch per foot minimum, has been lost to settlement or root intrusion from the parkway trees common along Sunnyvale’s Washington Avenue corridor.

AfterReplacement Cost & What’s Included
| Scope | Price Range in Sunnyvale |
|---|---|
| Paver driveway installation (new) | $7,000 - $18,000 |
| Concrete driveway installation (new) | $4,500 - $12,000 |
| Driveway replacement (remove and replace) | $5,000 - $14,000 |
| Paver patio installation | $3,500 - $11,000 |
| Driveway sealing (maintenance) | $250 - $700 |
| Spot paver repair / edge restraint replacement | $800 - $2,500 |
The range depends on three factors: paver material cost (concrete pavers run $3-$6 per square foot, natural stone $8-$15), base condition (whether we can reuse the aggregate or need to excavate and recompact), and access (narrow side yards in Sunnyvale’s postwar tracts add labor hours for wheelbarrow work). Every quote we write lists these separately - material, labor, disposal, base repair if needed - so you see where each dollar goes. Under Clause 1 of The Haven Standard, that written price is locked before work starts; no change proceeds without a signed change order. Our paver work carries the 365-Day Done Right Promise.
DIY or Call Us?
An owner can safely check three things: measure the sunken area’s dimensions, photograph the paver stamp or lot number, and verify whether water drains toward the foundation (a level and a bucket of water will tell you). What goes wrong with DIY paver repair is almost always the base - homeowners lift the pavers, add sand, and reset them without addressing the compromised aggregate or failed edge restraint. The repair looks fine in May and is wobbling again by November.
We don’t recommend DIY removal if the paver field borders a gas meter, irrigation valve box, or AC pad - common in Sunnyvale’s tight side setbacks - because the excavation risk isn’t worth the savings. Call (650) 405-3637 and we’ll scope it, write the price, and schedule the work.
FAQs
Concrete pavers rated for 8,000 PSI, properly installed with a compacted base and polymeric joint sand, typically last 25-30 years in Santa Clara County’s mild climate - longer than the national average because we avoid deep freeze-thaw cycles. The failure point we see at year 15-20 is almost always edge restraint degradation or tree root intrusion, not the paver itself. Call (650) 405-3637 for an exact quote on extending the life of your installation - estimates are free.
Yes, if the base is sound and the damage is limited to surface spalling or fewer than 10% of pavers in a defined area. We lift the affected section, regrade and recompact the bedding layer, and reset with matching material. If the base has settled or the edge restraint has failed, partial repair becomes false economy - the problem migrates. We’ll show you both options on the written quote. Call (650) 405-3637 for a free assessment.
A typical driveway replacement runs 3-5 working days: one day for removal and base prep, one for aggregate placement and compaction in lifts, one for paver laying and initial compaction, and one-two for joint sand and final compaction with a plate vibrator. Weather delays happen - we won’t compact wet base material, and Sunnyvale’s winter rains can push a schedule. We text confirmed start dates, not verbal promises. Call (650) 405-3637 to schedule your free estimate.
We stock Belgard and Techo-Bloc equivalents in 60mm and 80mm thicknesses at our Sunnyvale warehouse, and we can source OEM ES Windows material with a 5-7 day lead through their Ontario, California distribution center. For most repairs, the equivalent matches in profile and color; for warranty work or strict HOA requirements, we order OEM and schedule accordingly. Call (650) 405-3637 - we’ll verify your lot number and give you both options on the written quote.
Measure it twice, write it down, then build it. That’s how we’ve kept projects within a few percent of the agreed price across 4,000-plus jobs since 2007.
