Unilock Construction in El Cajon, CA | Penhallow Remodeling San Diego
We provide independent Unilock construction service across El Cajon, from full paver patio and driveway builds to structural repairs on older installations. The one thing that makes our Unilock work here different is that we build for El Cajon’s reality: mapped earthquake fault traces, expansive soils, and summers that bake polymeric sand until it crumbles. If your Unilock pavers are shifting, stained, or pulling away at the edges, call (619) 604-9624 and we’ll put a written price in your hand before any work starts.
Why El Cajon Residents Choose Us for Unilock Service
Unilock pavers aren’t a sideline for us. Our crews know the full lineup, from Brussels Block and Town Hall to EnduraColor and Elegance, and we’ve torn apart enough failing installations in El Cajon to know exactly where they break. Trevor Nash, our owner, came up through a trade program at Los Angeles Trade-Technical College and has spent the better part of two decades running remodeling crews across San Diego. That means when we diagnose a sinking driveway or a chalky patio, the recommendation comes from hands-on experience, not a sales script. We’re an independent contractor, not a manufacturer affiliate, so our loyalty is to the homeowner in El Cajon, not a parts quota. For full product background, see our Unilock sales & service page.

Common Unilock Construction Problems We Solve in El Cajon
- Polymeric sand degradation from intense UV and occasional downpours. El Cajon’s summer sun bakes joint sand until it loses its binder, then a single heavy rain flushes it out. Weeds follow. We remove the failed sand, re-level any shifted pavers, and install a high-performance jointing compound rated for our temperature swings. It costs more than the bagged stuff from the hardware store and it’s worth every dollar.
- Edge restraint failure on driveways bordering sandy, expansive soil. When the soil under a driveway edge expands and contracts, a flimsy plastic edge restraint will pull loose and let pavers creep outward. We see this constantly on older El Cajon homes. Our fix is a reinforced aluminum restraint driven below the base layer, not staked into it.
- Efflorescence bloom on tumbled concrete pavers like Brussels Block. Hard irrigation water plus low humidity pulls mineral salts to the paver surface, leaving that white chalky haze. It’s not a defect, but it looks like one. We can clean it and, where the water source is the culprit, recommend better drainage or irrigation routing so it doesn’t return six months later.
- Cracking at stress points on paver steps and caps. Tree-root pressure and the seismic micro-movements common in El Cajon concentrate force at step corners and wall caps. A cracked cap isn’t just cosmetic, it lets water into the wall and accelerates failure. We replace damaged units with genuine Unilock material so the color and dimensions match.
- Sunken sections from base washout. Broken downspouts and poor drainage are the hidden culprits behind most sinking pavers in El Cajon. We don’t just lift and relay; we find what washed the base out and fix that too, otherwise the same section sinks again.
Unilock Service in El Cajon: What Local Conditions Mean for Your Hardscape
Here’s something most San Diego contractors never have to think about: El Cajon sits atop several mapped earthquake fault traces, including the El Cajon Fault. A hardscape that survives fine in coastal neighborhoods built on stable sandstone may not hold up here when the ground oscillates. That’s why any Unilock installation or major repair we do as a General Contractor in El Cajon starts with a deeper, properly compacted base and flexible edge restraints that can absorb movement without failing. On homes off Avocado Avenue, where we found a 1962 ranch with a Town Hall driveway sunk two inches at the garage apron, the original installer had used decomposed granite that washed out from a broken downspout. We rebuilt that section with 4 inches of Class II road base and a reinforced aluminum edge restraint. The owner drives in without the thump now, and the new permeable joint sand doesn’t wash out. That’s the difference between patching a symptom and addressing what El Cajon’s geology actually does to a hardscape.
Unilock Models & Products We Service in El Cajon
Our crews handle the Unilock lines most common in El Cajon: Brussels Block for its classic tumbled look, Town Hall for driveways and larger paved areas, and EnduraColor and Elegance for homeowners who want sharper color retention and a more contemporary finish. We recommend genuine Unilock replacement units for visible patios, steps, and any area where color mismatch would stand out. For structural work like base stabilization, we use premium locally sourced aggregates and edge restraints that outperform the generic big-box options. And we’ll tell you plainly when a full lift-and-relay is the smarter buy versus patching a section that’s going to fail again. No mystery, just a straight answer and a written price.
Unilock Service Pricing in El Cajon
| Service | Typical Range in El Cajon |
|---|---|
| Paver Patio Installation | $3,500 – $11,000 |

What moves the number? Square footage, access to the site, whether we’re pulling up and hauling away an old concrete slab, and how much base material the existing soil needs. In El Cajon, we’re often adding more compacted base than a coastal job would require, because the soil here expands and contracts. Every quote we write is a fixed number, not a range you hope will hold. You’ll know the price before a single paver gets pulled. Call (619) 604-9624 and we’ll come out, look at what you’ve got, and hand you a written estimate.

FAQs – Unilock Construction in El Cajon
That white residue is efflorescence, which happens when hard irrigation water and El Cajon’s low humidity pull mineral salts up through the paver surface. We can clean it with the right chemical treatment, but if your irrigation is spraying the patio directly, the stains will return. We’ll assess the water source and recommend a fix that lasts, not a rinse-and-repeat cleaning. Call (619) 604-9624 for an exact diagnosis and price.
Most likely, the original sand wasn’t rated for El Cajon’s temperature swings, or the joints were too wide, or water is flowing across the surface and eroding it. We remove the failed material, correct the drainage where needed, and install a higher-grade jointing compound that holds through our heat and the occasional heavy rain. The fix is priced by square footage, and we’ll give you a written number before we start.
Yes, in most cases. Unilock pavers fade somewhat with age, especially in El Cajon’s sun, so a brand-new unit placed next to a weathered one will look slightly different. We can source the closest current production run and sometimes blend new and existing units to minimize the visual shift. We’ll show you samples before committing.
In most cases, no, if you’re keeping the same footprint and not changing drainage patterns. But if the work involves altering grade, adding retaining walls, or changing how water flows off the property, a permit may be required. We’ll check the specific requirements for your property in El Cajon and tell you straight whether a permit is needed for your El Cajon Bathroom Remodeling or hardscape project before anything gets ordered.
For a 600-square-foot patio in El Cajon, a full lift-and-relay with base correction typically falls between $4,200 and $9,000, depending on how much new base material is needed and what’s causing the sinking. If it’s straightforward compaction, you’re at the lower end. If we’re fixing drainage and rebuilding the edge restraints too, the number climbs. We’ll give you one written price for the whole job. Call (619) 604-9624 to schedule a look.
