Why San Diego Homeowners Choose Unilock Construction
We’re an independent Unilock service provider in San Diego, and we handle paver driveways, patios, walkways, and retaining walls with a level of detail most general contractors don’t get into. The difference comes down to this: we know how Unilock pavers behave in San Diego’s specific soil conditions, and we diagnose problems before they spread. This page is built for San Diego homeowners who already own Unilock products or are considering them, and want a crew that actually understands the product, not just the category. Call (619) 604-9624 to talk through what you’re seeing.
Trevor Nash, our owner, grew up in Los Angeles and picked up his first framing hammer in a trade program at Los Angeles Trade-Technical College. He learned early that honest measurements matter more than anything else. That’s the lens we bring to every Unilock in Chula Vista and San Diego project, whether it’s a Mission Hills patio extension or a full driveway replacement in Clairemont.
Why Trust Penhallow Remodeling San Diego for Your Unilock Construction?
Unilock pavers are not a sideline for us. Our technicians have diagnosed and rebuilt paver systems across San Diego and El Cajon Unilock service areas that failed due to hard water, expansive clay soils, and coastal salt air. We see the same failure patterns repeat across Unilock installations in this region, and that field experience means we can often pinpoint the cause of a problem in the first visit rather than guessing through multiple trips.
Here’s what that looks like in practice. When a paver surface heaves or sinks in San Diego, it’s rarely the paver’s fault. It’s almost always the base, or the edge restraint, or drainage. We diagnose the system, not just the symptom. That approach saves San Diego homeowners real money because it prevents us from selling a full tear-out when a targeted repair would hold for years. We use genuine Unilock replacement units when we can source them, and when we can’t, we match the texture and color blend as closely as possible with premium compatible pavers. We never pretend a repair is authorized by Unilock, because we’re an independent provider, and we believe you should know exactly who’s doing the work and who stands behind it.
The Kingswell Way, our operating standard since 2004, applies to every Unilock job in San Diego. A written price before any work starts. A defined arrival window. A clean job site. And a written guarantee on every project. It’s not marketing language. It’s the same standard we’ve applied to kitchen remodels, bathroom work, and paver installations across the city.

Common Unilock Construction Problems We Fix in San Diego
San Diego’s climate and geology create a specific set of failure modes for Unilock pavers. These are the ones we see most often:
- Efflorescence whitening on Unilock Brussels Block driveways. Hard water from San Diego irrigation systems leaves mineral deposits that wick through the paver and crystallize on the surface as a white haze. It looks like the paver is fading, but it’s a mineral reaction, not a product defect. We remove it and adjust the irrigation or drainage that caused it, so it doesn’t return in six months.
- Settling and heaving on paver driveways from San Diego’s clay-rich, shrink-swell soils. Expansive clay expands when wet and shrinks when dry. That cycle moves the soil under the pavers, creating low spots and ridges. The fix requires removing the affected band, recompacting the base, and often adding road-grade gravel for stability, not just adding more sand. This is the most common driveway problem we encounter in neighborhoods like Mira Mesa and Clairemont.
- Paver joint-sand washout and weed intrusion on Unilock Richcliff patios near coastal bluffs. Near the coast, wind and rain strip the joint sand faster than inland. Once the joints are empty, weeds root in the remaining material and push pavers apart. We replace the joint sand with a stabilized polymeric product after cleaning, which locks the surface together and resists both erosion and weeds.
- Edge restraint failure causing Unilock Town Hall borders to spread open under vehicle loads. The border units on a driveway take lateral force every time a car turns or stops. If the original install used a thin plastic edge restraint or none at all, the borders push outward and the pattern opens up. We install proper aluminum or concrete edge restraint, reset the borders, and tighten the pattern.
- Sunken bowls across Unilock Series 3000 surfaces where the clay sub-base dried unevenly. In areas with inconsistent irrigation or large tree roots, the clay under the pavers dries at different rates, creating localized settlement. On a University City driveway, we found the Series 3000 surface had shifted into three distinct sunken bowls. We removed the affected bands, recompacted the base with road-grade gravel, and reinstalled the same pavers with new edge restraints. No visible patching, and the trip hazard was gone.
Unilock Parts & Our Repair-vs-Replace Approach
We take a straight approach to every Unilock repair: show you both options and let the math do the talking.
Genuine Unilock replacement units are our first choice when we can source them from local San Diego suppliers. Unilock manufactures in North America, but specific color blends and product lines come in and out of regional availability. When we can’t source the exact unit, we match the texture and color blend as closely as possible using premium compatible pavers from other manufacturers. We tell you which path we’re taking before we start, not after.
The repair-vs-replace decision comes down to three questions. How old is the installation? How widespread is the failure? And what does the customer actually want the paver surface to do over the next decade? A single settled area on a five-year-old patio is usually a repair. A 20-year-old driveway with failing base material across half the surface is usually a replacement. We quote both numbers when the answer isn’t obvious, so you can weigh cost against longevity with real figures in front of you.
For pricing: Paver driveway installation in San Diego runs $8,260 to $21,240. Paver patio installation typically runs $4,130 to $12,980. Full driveway replacement runs $5,900 to $16,520. Call (619) 604-9624 for an exact written quote on your specific project.
Our Unilock Service Process – Step by Step
No job starts until you understand what’s happening and what it will cost. Here’s how we handle Unilock service in San Diego:
- 1
Diagnosis. We inspect the paver surface, check the base material, assess drainage, and identify the failure mode. For Unilock issues in San Diego, that means looking specifically at soil movement, irrigation overspray, and edge restraint condition.
- 2
Written quote. We put the repair or replacement price in writing before any work starts. Not a range, not a verbal ballpark. A number you can hold us to.
- 3
Repair or install. For repairs, we remove the affected pavers, recompact or rebuild the base as needed, reset or replace the edge restraints, and reinstall matching units. For new installs, we build the base properly from day one: excavation, road-grade gravel compaction, bedding sand, pavers, edge restraint, and joint sand.
- 4
Testing and verification. We check drainage by running water across the surface and observing flow. We walk the full area looking for lippage, loose units, or unstable edges. We verify the pattern is tight and the slope is correct.
- 5
Written guarantee. Every job includes our 365-Day Done Right Promise in writing. If the work fails inside the guarantee period, we come back and fix it at no charge. No service call fee, no re-inspection fee.

FAQs – Unilock Construction Service in San Diego
Yes, in most cases. We source genuine Unilock Beacon Hill Flagstone units when the blend is available from our San Diego suppliers. When a specific color run is discontinued or out of region, we match the dominant tones and texture using premium compatible pavers. We show you samples side by side against your existing surface before any work begins, so you can approve the match first. Call (619) 604-9624 for a free estimate on your extension.
The white haze is efflorescence, a mineral deposit caused by hard water from irrigation that wicks through the paver and crystallizes on the surface. It’s common in San Diego because our water carries high mineral content. The fix is removing the deposit and correcting the water source so it isn’t repeatedly soaking the pavers. We can walk you through exactly what’s causing yours. Call (619) 604-9624 and we’ll take a look.
Usually not. Isolated settlement on a Unilock Richcliff patio in San Diego is typically caused by localized base failure or drainage issues, not a problem with the entire installation. We remove the sunken section, rebuild the base, and reinstall the same or matched pavers. A full replacement is only necessary when the base has failed broadly or the pavers are severely damaged. Call (619) 604-9624 and we’ll give you a straight answer with both options priced.
For coastal San Diego properties, we recommend a penetrating silane-siloxane sealer specifically formulated for concrete pavers. It protects against salt air and moisture without leaving a surface film that can trap efflorescence under the surface. Film-forming acrylic sealers tend to peel in our marine layer conditions and are not what we usually recommend. We can match the right sealer to your specific Unilock product and exposure.
The border spreads because the edge restraint isn’t holding it under lateral pressure. We remove the border units, install proper aluminum or concrete edge restraint anchored below the base material, reset the borders, and recompact the area. That fixes the root cause rather than just pushing the pavers back together, which would fail again under vehicle loads. This is a common repair on San Diego driveways where cars turn sharply at the curb line.
No. We are an independent Unilock service provider, not an authorized dealer or installer. That means we work for you, not the manufacturer, and our recommendations are based on what’s best for your specific San Diego property, not on protecting a dealership agreement. We source genuine Unilock products when available and use quality compatible alternatives when they’re the better fit for the repair.
Yes, we use genuine Unilock replacement units when we can source them from our San Diego suppliers. When a specific product line or color blend isn’t available, we use premium compatible pavers matched as closely as possible to the existing texture and color. We always tell you which path we’re taking before the work starts.
Work performed by an independent service provider does not void the manufacturer’s product warranty, which covers material defects in the pavers themselves. Installation and workmanship issues are not covered by the manufacturer’s warranty in the first place, which is why we provide our own written guarantee on every repair and installation. Our 365-Day Done Right Promise covers our work in writing for a full year.
