Unilock Construction in Folsom, CA | Penhallow Remodeling Sacramento
We provide our Unilock services for paver and wall construction across Folsom, from new driveway and patio installs to repairs on shifting or spalling stone. What makes our Unilock work different here is simple: we know what Folsom’s expansive clay does to interlock systems, because we’ve dug out enough failed bases in Prairie Oaks and Empire Ranch to recognize the pattern before it costs you a second rebuild. Call (279) 300-1177 for a straight answer and a written price.
Why Folsom Residents Choose Us for Unilock Service

We’re a Folsom service area remodeler that treats paver installation like the structural job it actually is. Unilock stones are only as stable as the base beneath them, and base failure is the root cause of nearly every shifting patio or lipped driveway we’re called to fix in this city. Trevor Nash, who owns Penhallow Remodeling Sacramento, started in the trades at Los Angeles Trade-Technical College and spent two decades swinging a hammer across Southern California before bringing that experience to Sacramento. He’s the one who walks your yard, points to the low spot, and tells you exactly why water is pooling there and what it’ll take to keep your pavers flat.
We use Unilock OEM replacement pavers and caps whenever a repair calls for matching color and size. We don’t cut corners with generic stone that looks close under fluorescent light but wrong in your backyard at noon. You’ll also get our 365-Day Done Right Promise in writing: if the work fails inside a year, we come back and make it right at no charge. That’s the Kingswell standard, and it applies to every Unilock project we touch in our Bathroom Remodeling in Folsom and across all our work.

Common Unilock Construction Problems We Solve in Folsom
- Paver shifting and lippage on clay-heaved bases. Folsom’s expansive clay shrinks and swells with moisture changes, and when a patio base wasn’t compacted over a clay lens, the stones move with it. We see this constantly in Prairie Oaks, where back patios poured without proper compaction start showing trip-hazard edges within five years.
- Efflorescence and face spalling from winter freeze-thaw. Folsom gets real frost in the winter months, and older Unilock stones with saturated faces can spall when water freezes inside the surface pores. That white, chalky efflorescence isn’t just cosmetic – it’s usually the first sign that moisture is moving through the stone in a way it shouldn’t be.
- Polymeric sand joint erosion on sloped driveways. Empire Ranch has some of the steeper residential grades in the city. Heavy runoff during winter rains scours joints between Unilock Hollandstone pavers, washing out the polymeric sand and leaving stones loose enough to rock under a car tire.
- Retaining wall leaning from inadequate drainage. Rivercrest Wall blocks hold soil beautifully when the water behind them has somewhere to go. On Folsom’s hillside lots, a wall built without proper gravel backfill and weep holes will start leaning within a few seasons as hydrostatic pressure builds.
- Permeable paver installations that weren’t spec’d right for clay. Unilock’s Eco-Priora permeable system works well in Folsom, but the base spec is different from what a standard paver needs. We’ve corrected installations where contractors used the wrong aggregate gradation, leaving the surface too porous in one spot and too tight in another.
Unilock Service in Folsom: What Local Conditions Mean for Your Equipment

Folsom’s city code requires permeable pavement for new driveways in certain planned-unit developments, and Unilock’s Eco-Priora permeable pavers are one of the few systems that satisfy that requirement while still handling the heaving tendency of our clay soils. This isn’t a generic solution – it’s the specific answer to a regulatory problem Folsom homeowners face that residents of, say, Roseville don’t deal with the same way. Prairie Oaks homeowners ask us about Eco-Priora specifically after watching neighbors’ standard slab driveways heave and crack within five years. The way the open-graded base under Eco-Priora manages water movement actually reduces the moisture cycling that drives clay expansion, which means the paver system works with the soil rather than fighting it.
That field experience carries over to every Unilock job we quote in Folsom. We know which sub-base depths hold up on the clay lenses behind Empire Ranch, and we know where to add geogrid reinforcement when the grade slopes hard toward the street.
Unilock Models & Products We Service in Folsom
We install and repair Unilock’s workhorse lines that fit Folsom’s housing stock and soil conditions. Estate Paver handles the wide, sweeping driveways common in newer planned communities. Hollandstone works well for traditional patios and walkways around older homes near Historic Sutter Street. Rivercrest Wall gives you a clean retaining wall face that stands up to hillside work, and Lineo Dimensional Stone is popular for clean-edged patio borders and steps. We keep OEM Unilock caps and replacement pavers in common sizes available for quicker turnaround, but anything non-stock gets ordered with full transparency on lead time before we start.
Our approach is honest replace-vs-repair. If your base is failing, we tell you it’s a re-base job and explain why surface patching won’t last. If it’s just worn joints and good base underneath, we repair rather than tear out. We’re not interested in selling you a rebuild that doesn’t need to happen.

AfterUnilock Service Pricing in Folsom

Here’s what you can expect to pay for Unilock work in Folsom, based on current Sacramento market pricing:

| Paver Patio Installation | $3,500 – $11,000 |
| Driveway Sealing | $250 – $700 |
What drives the number up or down? Square footage, base condition, excavation depth, and whether you need geogrid or specialized aggregate for clay mitigation. Accessibility matters too: a tight side yard in an older Folsom neighborhood means more wheelbarrow work than an open backyard in Empire Ranch. A free estimate from us means Trevor walks the site, checks the base, and gives you a written number with no change orders after demo day. Call (279) 300-1177 to schedule yours.

FAQs – Unilock Construction in Folsom
Pavers heave in these neighborhoods because the original patio or driveway slabs underneath were often poured over clay lenses without proper compaction, and Folsom’s expansive clay shrinks in summer heat and swells with winter moisture, forcing the stones out of plane. Our crews dig down to the base, remove the clay lens, add compacted aggregate and geogrid where needed, then relay the pavers. Call (279) 300-1177 for an exact quote on your specific yard.
Yes. We use Unilock OEM replacement pavers and caps to match the existing color, size, and finish on your patio. If the manufacturer still produces that line, we get it. If it’s discontinued, we’ll be straight with you about your options upfront. Call (279) 300-1177 and we’ll identify your specific Unilock product during a free estimate.
Folsom’s city code does require permeable pavement for new driveways in certain planned-unit developments, and Unilock’s Eco-Priora permeable pavers are one of the systems that meets that requirement. We check the specific code requirements for your property before we spec any replacement so you don’t get surprised by a permit issue. Call (279) 300-1177 to find out what applies to your driveway.
Look for the wall starting to lean or bulge outward, especially near the bottom courses. Efflorescence staining the face of the blocks is another warning sign: water is moving through the wall instead of draining behind it. In Folsom’s clay, winter rains build up hydrostatic pressure fast, and a Rivercrest wall without proper gravel backfill and weep holes will keep leaning until it fails. Call (279) 300-1177 for a wall inspection – estimates are free.
Most Folsom paver driveways need resealing every two to three years to keep efflorescence controlled and the surface protected from our freeze-thaw cycles. The exact interval depends on sun exposure, drainage, and how much water sits on the surface. Driveway sealing runs $250 to $700 in this market. Call (279) 300-1177 and we’ll tell you whether a reseal is enough or if you’re due for joint replacement.
