Why Miami Homeowners Choose Unilock Construction
We’re an independent Miami Unilock service provider, and we install and repair Unilock pavers, walls, and driveways without pretending to be factory reps. Our crews have worked on hundreds of Unilock projects across Miami-Dade, from Coral Gables driveways to Brickell condo walkways, so we know exactly how these concrete products hold up in salt air, 90% humidity, and afternoon thunderstorms. We use genuine Unilock pavers for color-matched repairs and commercial-grade aftermarket adhesives and sealers that actually survive South Florida conditions. Call (850) 988-7559 for a free estimate, and we’ll give you a written number before any work starts.
Why Trust Penhallow Remodeling Miami for Your Unilock Construction?
Trevor Nash, the owner of Penhallow Remodeling Miami, learned the trade at Los Angeles Trade-Technical College and has spent three decades managing crews on everything from small bath refreshes to full structural overhauls. When it comes to Unilock work, he’s the guy who shows up with a written estimate before anything else gets discussed. That’s not a sales tactic. It’s how we operate under The Kingswell Way, which since 2004 has required a written price before work starts, a defined arrival window, a clean job site, and a written guarantee on every project.
Our technicians know Unilock product lines by name: EnduraColor, Town Hall, Brussels Block, Estate Wall. We’ve pulled up failed paver beds in Little Havana and Allapattah where the base prep was done wrong, and we’ve re-laid entire driveway sections in Coral Gables where joint sand had turned to mush. Background-checked, uniformed technicians arrive on every job, and a live person answers our phone 24/7. No answering service. No voicemail maze.
But the thing that matters most is this: we back every Unilock repair with a 365-Day Done Right Promise in writing. If the work fails inside a year, we come back and fix it at no charge. That’s not a verbal assurance. It’s on the invoice.

Common Unilock Construction Problems We Fix in Miami
- Efflorescence on Charcoal and Sierra pavers. That white powdery streak you see on dark Unilock pavers isn’t a defect. It’s mineral salts wicking up through the concrete as Miami’s constant humidity pushes moisture through the paver body. We see it most often on Unilock EnduraColor Charcoal and Sierra because dark colors make the white deposit obvious. The fix is a proper cleaning with efflorescence-specific cleaners, then sealing with a commercial-grade penetrating sealer rated for South Florida’s wet conditions. Store-bought sealers won’t hold up.
- Joint sand washing out after afternoon downpours. Miami gets 60+ inches of rain a year, much of it in daily thunderstorms. Regular joint sand doesn’t survive that. It washes out, the pavers shift, and the patio starts looking like a wave pool. We re-sand with polymeric sand that hardens after moisture exposure, locking the pavers in place. On some Unilock installations we’ve pulled up, the original contractor used cheap builder’s sand, and the paver bed was already shifting within six months.
- Edge restraint failure on driveways. Unilock driveways in Miami take a beating from repeated SUV loads. If the edge restraint wasn’t installed properly, or the base prep was thin, the borders drift outward and the whole installation loses its tension. We pull the edge pavers, install proper aluminum or concrete edging, and re-compact the base before re-laying the blocks. This is the most common driveway failure we see in neighborhoods like Allapattah where older concrete-block homes have seen decades of soil movement.
- UV color fade on budget Unilock lines. Cheaper Unilock product lines fade after years of direct Miami sun. The pigment in standard concrete pavers oxidizes under intense UV exposure, and by year five or six, the color is noticeably lighter than the sample you originally approved. EnduraColor holds up much better because the color is embedded in the top layer during manufacturing, not just applied as a surface treatment. We steer Miami homeowners toward EnduraColor for any full-sun installation.
- Base settlement on older Unilock installations. Miami sits on porous limestone, and soil movement is a constant reality. Older Unilock paver jobs, especially those installed without proper crushed limestone base, settle unevenly over time. You’ll see a paver section dip four inches, hold water after a storm, or crack under the stress. The repair isn’t a patch job. We lift the affected section, add fresh base material, compact it, and re-lay the original pavers. Patching a settled section without fixing the base is just asking for a callback.
Unilock Parts & Our Repair-vs-Replace Approach
For color-matched paver replacements, we use genuine Unilock pavers. Off-brand or mismatched pavers stand out like a sore thumb, and you’ll see the patch every time you walk to your front door. Genuine Unilock product guarantees the color, texture, and dimensions match the surrounding installation. But for adhesives and sealers, we choose commercial-grade aftermarket products. South Florida’s humidity, salt air, and standing water demand products that outperform what the manufacturer ships for national markets. A penetrating sealer rated for coastal conditions will protect better than a general-purpose product.
How we decide repair versus replace comes down to honesty. If a paver has a hairline crack, we repair it. If a whole section has shifted or settled from poor base prep, we lift and re-lay the layer rather than patching indefinitely. Patching a symptom without fixing the cause is what gives contractors a bad name. Trevor’s signature phrase sums it up: give you a number first, then pick up the tools. That means we tell you what the job actually needs, even if it’s not the cheapest option. Call (850) 988-7559 to talk through what your Unilock installation needs, and we’ll give you a straight answer.
Our Unilock Service Process – Step by Step
Every Unilock job in Miami follows the same written-in-stone process. No shortcuts, no mystery.
- 1
Diagnosis. We walk the site with you, inspect the paver bed, check for base settlement, measure drainage patterns, and document every issue. For Unilock driveways, we check edge restraint tension and joint sand condition. You get a written diagnosis with our findings before we quote anything.
- 2
Repair or install. We put the written price in your hand first. That number is the number on the invoice, not an estimate range. Our crew pulls up any failed sections, adds fresh crushed limestone base where needed, re-compacts, and lays genuine Unilock pavers with proper edge restraint. For new installations, we follow the same base prep standards Unilock requires for warranty compliance.
- 3
Testing. We run water across the finished surface to verify drainage. Miami’s rainfall makes this non-negotiable. If water pools, we adjust before we call the job done. We also walk the surface to check for any shifting underfoot.
- 4
Warranty. Every Unilock job comes with our 365-Day Done Right Promise in writing. If the work fails inside a year, we return and fix it at no charge. No service call fee, no re-inspection fee, no debate. That’s the guarantee we’ve operated under since 2004.

AfterUnilock Products We Service & Install in Miami
We work on the Unilock lines Miami homeowners actually have installed. Unilock EnduraColor is the workhorse for driveways and high-traffic walkways here because its color won’t fade under our sun the way cheaper lines do. Unilock Town Hall shows up often on patios and pool decks in Brickell and Edgewater. Brussels Block is the classic rounded-edge paver we see on older Miami-Dade properties, and we re-lay plenty of those when the base gives out. Unilock Estate Wall is the retaining wall system we install most often for Coral Gables and Coconut Grove homes dealing with grade changes. We stock common Unilock pavers locally for color-matched repairs, and we order special lines with a short turnaround.
We Also Service These Brands
Unilock isn’t the only brand we handle. We install and service KraftMaid and Wellborn cabinetry, Cambria and Silestone countertops, and Kohler and Moen fixtures. If your Miami home needs a full remodel that includes hardscape work, we can handle the entire project as your General Contractor services under one written price and one written guarantee.
FAQs – Unilock Construction Service in Miami
That white powder is efflorescence, and it’s caused by mineral salts migrating through the concrete paver as Miami’s constant humidity and rainfall push moisture through the material. It’s more visible on dark Unilock colors like Charcoal and Sierra. The fix is proper cleaning with an efflorescence-specific product, followed by sealing with a commercial-grade penetrating sealer rated for South Florida’s coastal conditions. We see this constantly on older Unilock installations where the original sealer has worn off. Call (850) 988-7559 and we’ll assess your patio and give you a written price to clean and seal it properly.
Yes, in most cases. We maintain relationships with Unilock suppliers and can often source discontinued colors through distributor inventory or special order. When a color is truly gone, we can blend a match from available lines or recommend a complementary color that transitions cleanly. This is one of the biggest advantages of working with a contractor who knows Unilock product lines by name, not just by the sample board. Give us a call at (850) 988-7559 with the color name or a photo, and we’ll tell you honestly whether we can match it.
Unilock pavers themselves hold up well in Miami’s climate, but the installation details decide whether your patio survives or shifts. The base prep, edge restraint, and joint sand all matter more than the paver brand. We use crushed limestone base material, proper compaction, aluminum or concrete edge restraints, and polymeric joint sand on every Unilock installation in Miami. That combination resists the washout and settlement that cheaper installations suffer. If your existing paver patio holds water after a storm, that’s a drainage or settlement problem, not a paver defect. Call (850) 988-7559 for a free estimate, and we’ll diagnose exactly what’s happening.
It depends on the total condition. If you have one or two cracked pavers with a stable base, we repair by replacing the individual units with genuine Unilock color-matched pavers. If the cracking is widespread or the base has settled, replacing individual pavers is just a temporary patch. In that case, we recommend lifting the affected section, adding fresh base material, compacting, and re-laying the original pavers where possible. This approach costs less than a full replacement but gives you a stable driveway that drains properly. Paver driveway replacement in Miami typically runs $8260 – $21240 depending on square footage and base condition. Call (850) 988-7559 and we’ll give you a written recommendation based on what we actually see.
Unilock’s manufacturer warranty covers the pavers themselves, independent of who installs them. That said, Unilock’s warranty does not cover installation defects like improper base prep, missing edge restraint, or joint sand failure. Those issues fall on the contractor who did the work. As an independent Unilock service provider, we are not affiliated with or authorized by Unilock, but we back every installation and repair with our own 365-Day Done Right Promise in writing. If our work fails inside a year, we fix it at no charge. Period. That’s the guarantee we’ve operated under since 2004.
Unilock paver patio installation in Miami typically runs $4130 – $12980. Paver driveway installation runs $8260 – $21240, and concrete driveway installation runs $5310 – $14160. These ranges reflect Miami-Dade’s specific conditions: porous limestone substrate, hurricane wind-load requirements, and the need for proper drainage layers that many homeowners don’t see but absolutely need. Here’s a breakdown of what drives the price:
| Service | Miami Price Range |
|---|---|
| Paver Patio Installation | $4130 – $12980 |
| Paver Driveway Installation | $8260 – $21240 |
| Concrete Driveway Installation | $5310 – $14160 |
Square footage, base prep depth, paver line selection (EnduraColor costs more than standard lines but holds its color longer), and accessibility all move the number. You’ll get a written price from us before any work starts, and that’s the number you pay. Call (850) 988-7559 for a free estimate.
