Unilock Construction in Miami, FL | Penhallow Remodeling Miami
We provide independent Unilock paver and wall installation, repair, and replacement across Miami, and we do it with a written price before any work starts. The thing that makes our Unilock work here different is simple: we build for Miami’s limestone, salt air, and afternoon downpours, not for a generic Florida postcard. If you have a Unilock driveway, patio, or retaining wall that is failing, call (850) 988-7559 and we will tell you exactly what is wrong and what it costs to fix.
Why Miami Residents Choose Us for Unilock Service
Our crews have spent years installing and repairing Unilock pavers and walls across Miami’s toughest conditions, so we know which products hold up and which fail when hurricane winds and humidity attack. That experience means we do not guess. We pull the pavers, look at the base, and show you what we found before we quote a number.
Trevor Nash grew up in Los Angeles and learned the trade at Los Angeles Trade-Technical College, then spent the better part of three decades swinging a hammer and managing crews on jobs from small bath refreshes to full structural overhauls. He and his team have been working throughout Miami for years as a General Contractor - Miami, including plenty of projects in Coconut Grove where older homes tend to have a story hiding behind every wall. Trevor is known for showing up with a written estimate before anything else gets discussed and for being straight with homeowners about what a job actually involves. His ethos is simple: give you a number first, then pick up the tools.
We are an independent Unilock service provider. We are not manufacturer-affiliated or authorized, which means our recommendation is based on what works in Miami, not what a brand rep tells us to push. That independence is why homeowners call us when a paver job fails and they want someone who will actually fix it.
We also handle Unilock sales & service for full installations, not just repairs. If you are building new, we can help you choose the right paver line for your specific site conditions.

Common Unilock Construction Problems We Solve in Miami
Unilock makes a solid product. But Miami’s climate and soil find the weak points in any installation. Here are the five problems we see most often:
- Efflorescence on pavers. Miami’s constant high humidity and frequent heavy rain pull salts up through the concrete, leaving a chalky white residue that homeowners mistake for permanent stains. It is not permanent, but the cause matters. We clean it and, more importantly, address the drainage issue that keeps feeding it.
- Settled and shifted pavers at pool decks and driveways. Miami’s porous limestone shifts under repeated saturation. A driveway that looked flat in March can be two inches low at the apron by September. The fix is rarely just releveling. The base underneath is usually the problem.
- Edge restraint failure. In older Miami installations, especially after hurricanes rip out original plastic edging, paver borders sink or spread. Once the edge goes, the whole field starts walking. We replace plastic edging with steel or aluminum restraint that actually holds.
- Polymeric sand washout. Heavy afternoon downpours blast the joint sand right out of the gaps. Then pavers rock, weeds sprout, and the surface feels loose underfoot. We re-sand with a properly activated polymeric product and make sure the drainage is moving water off the surface, not through the joints.
- Failed base under the pavers. This is the big one. A paver surface is only as good as what is underneath it. In Miami, that often means loose sand over limestone that was never compacted properly in the first place. We excavate, rebuild the base with compacted aggregate, and reinstall the pavers so they stay put.
Unilock Service in Miami: What Local Conditions Mean for Your Pavers
Many Miami homes sit on fill dirt over oolite limestone. In Coral Gables specifically, a 2,000 psi concrete base under a Unilock driveway is not enough. Miami-Dade code often requires a 3,000+ psi reinforced slab or deep compacted aggregate because the limestone reacts with groundwater during king tides. The ground literally moves under your pavers. Add 60+ inches of annual rainfall, 90% humidity, and direct Atlantic salt air, and you have a recipe for base failure that contractors in Broward or Palm Beach simply do not face to the same degree.
We were called to a 1950s CBS home in Little Havana where the original Unilock Brussels Block driveway had sunk two inches at the apron. Our crew pulled the pavers and found no compacted base, just loose sand over limestone that had settled from years of afternoon storms. We excavated eight inches, added geotextile fabric, compacted crushed concrete, reinstalled the same pavers with only five cracked units replaced, and locked the edges with steel restraint. A year later, the owner says it still drains flat before the next thunderstorm. That is what building for Miami actually means.
Unilock Models & Products We Service in Miami
We install and repair the full range of Unilock residential hardscape products, including Beacon Hill Flagstone pavers, Brussels Block pavers, Olde Greenwich Cobble pavers, and the U-Cara Multi-Face Wall System. Each line has a different joint pattern, thickness tolerance, and base requirement, and we match the repair to the product correctly.
For repairs, we use genuine Unilock replacement pavers and matching color blends whenever the original series is still in production. That keeps patches invisible. When a paver is severely faded, spalled, or the installation base has failed, we recommend replacing the affected section with a new compacted base and fresh joint sand rather than trying to glue broken units back together. Glue does not fix a failed base. We keep common Unilock colors and sizes stocked locally for fast Miami turnaround, which means less waiting when you need a repair before rainy season.
We serve the whole Miami service area, from older CBS neighborhoods in Little Havana and Allapattah to newer builds along Brickell and Edgewater.

AfterUnilock Service Pricing in Miami
Every job gets a written price before work starts, so the number you see is the number on the invoice. That is not a marketing line. That is how Trevor runs the company. Here are the market-calibrated ranges for the most common Unilock-related jobs we handle in Miami:
| Service | Typical Price Range |
|---|---|
| Paver Driveway Installation | $8,260 – $21,240 |
| Paver Patio Installation | $4,130 – $12,980 |
| Concrete Driveway Installation | $5,310 – $14,160 |
| Driveway Replacement (failed Unilock base) | $5,900 – $16,520 |
What drives the cost up or down? Depth of the base excavation, whether geotextile fabric and steel edging are needed, paver thickness, and how much of the old material can be reused. A patio on compacted soil is a different job than a driveway on loose fill over limestone. Call (850) 988-7559 for an exact quote. Estimates are free, and we put the number in writing before any tools come off the truck.

FAQs – Unilock Construction in Miami
That white residue is efflorescence, which happens when Miami’s high humidity and frequent rain pull naturally occurring salts up through the concrete paver. It is cosmetic, not structural damage, but it often points to a drainage problem underneath. We clean the surface and fix the drainage so the cycle stops. Call (850) 988-7559 and we will take a look.
Yes, usually. If the original series is still in production, we source genuine Unilock replacement pavers in the matching color blend, so patches blend into the surrounding field. If the fading is too severe or the base has failed, we recommend replacing the affected section with a rebuilt base. Call (850) 988-7559 for a free assessment.
They can, but the installation method matters more than the paver itself. Miami-Dade codes often require a reinforced concrete slab or deep compacted aggregate base under hardscape in flood-prone areas, especially where limestone and king tides are factors. We build to those standards, not around them. If you want to know whether your existing installation meets code, call us and we will tell you straight.
No, and here is why. The patio is sinking because the base underneath is failing, likely due to water saturation loosening the fill over limestone. Releveling without rebuilding the base is a temporary fix that will sink again after the next heavy rain. We excavate, compact a proper base, and reinstall the pavers so they hold. Call (850) 988-7559 for a written price.
For a driveway that handles Hialeah’s intense afternoon downpours, we typically recommend Unilock Brussels Block or Beacon Hill Flagstone on a properly compacted base with steel edge restraint and a drainage plan that moves water off the surface. The paver choice matters less than the base. If you are pricing a new driveway, call (850) 988-7559 and we will give you a written number.
