Why Dallas Homeowners Choose Unilock Construction
We provide Dallas Unilock service as an independent contractor, from Brussels Block driveway resets to Estate Wall retaining repairs, and we’ve been doing it long enough to know exactly how North Texas clay and heat stress these systems. As an independent contractor, not a Unilock dealer or installer, we give you straight advice on whether a repair makes sense or a replacement is the smarter money. Dallas homeowners call Penhallow Remodeling Dallas when they want someone who understands Unilock products, gives a written price before work starts, and backs the job with our 365-Day Done Right Promise. Call (940) 204-5368 and we’ll talk through what you’re seeing.
Here’s what matters: our crews work on Unilock in Irving and across Dallas every week, from Oak Cliff bungalows with cracking EdgeStone walls to newer builds near White Rock Lake with Brussels Block driveways showing settlement. We know these products at the level you need when something goes wrong. Trevor Nash, Owner at Penhallow Remodeling Dallas, has spent years diagnosing paver failures that most contractors misread, and the difference shows in how long our repairs actually last.

Why Trust Penhallow Remodeling Dallas for Your Unilock Construction?
Most Dallas contractors treat Unilock pavers like any other paving stone, but a Brussels Block paver behaves differently in expansive clay than a generic concrete unit, and an Estate Wall block has stress points that matter when your retaining wall is holding back a slope. Trevor Nash grew up in Los Angeles and picked up his first framing hammer in a neighbor’s garage around age fourteen, then trained at Los Angeles Trade-Technical College and spent years doing everything from foundation repairs to full kitchen gut-outs before serving the Dallas area. That background taught him something most paver installers never learn: what’s underneath the surface decides whether the surface survives.
When you call us about a Unilock problem, we arrive with more than a clipboard and a rough quote. We arrive knowing the failure patterns specific to each Unilock product line, understanding how Dallas’s blackland prairie clay moves seasonally, and carrying the tools to diagnose whether the base is failing or just the surface units need attention. Our technicians are background-checked and arrive in uniform, so you know exactly who’s walking onto your property. We’re part of the Kingswell family of companies, operating to The Kingswell Way since 2004: say the price before the work, show up in the window we gave, leave the place cleaner than we found it, and put the guarantee in writing.
Give you a number before we pick up a tool, that’s the only way we know how to start. Whether you need a Brussels Block driveway reset or an Estate Wall column rebuilt, you’ll have a written price before anything gets pulled apart, and a written 365-Day Done Right Promise, so if something fails inside the guarantee window, we come back and fix it at no charge.

Common Unilock Construction Problems We Fix in Dallas
These are the Unilock failures we see most often in Dallas, and each one has a specific cause tied to our soil, our heat, or our water. If you’re seeing any of these, don’t guess at the fix. Call us and we’ll diagnose it properly.
- Edge spalling on Brussels Block pavers: Brussels Block units have a distinctive rounded edge profile that looks great but concentrates stress at the paver’s shoulder. In Dallas, where the highly expansive blackland prairie clay shifts with every seasonal moisture swing, pavers rub and grind against each other as the ground moves, and that shoulder is the first place to chip. Add thermal expansion from summer heat exceeding 100°F, and the edges start popping off within a few years. This isn’t a product defect. It’s a base and drainage problem expressing itself at the paver edges.
- Efflorescence on Richcliff pavers: Richcliff has a textured, stone-like face that holds moisture differently than smooth pavers. When sprinkler runoff repeatedly soaks the surface, salts in the concrete and the water migrate to the top and leave a white, chalky haze. It’s not structural damage, but it looks terrible and it won’t wash off. The fix involves correcting the drainage pattern and applying a proper cleaning and sealing regimen, not scrubbing harder.
- Settlement and waviness in Town Hall driveway pavers: Town Hall is a larger-format paver often used for driveways and heavy-load areas. In Dallas, where many homes sit on clay-heavy subgrades, poor base compaction under these larger units shows up as waves and dips within one to two seasons. The paver is fine. The compacted aggregate base underneath wasn’t prepared correctly for clay that expands when wet and shrinks when dry. In many Dallas neighborhoods, concrete driveways and walkways are poured with no expansion joints, so homeowners are used to cracking. Pavers should not crack like that, and when they sink, it’s almost always the base.
- Fading and chalking on older Unilock pavers: Dallas gets intense UV year-round, and summer heat exceeding 100°F breaks down the pigment and surface polymers on older Unilock pavers that were never sealed. The color goes chalky and flat, especially on red and charcoal tones. Sealing isn’t just cosmetic in this climate. It’s the difference between a paver that looks new in ten years and one that looks twenty years old in four.
- Estate Wall blocks cracking at the bottom corners: Estate Wall is a split-face retaining wall block that’s built to hold back soil, but when the base course sits on inadequately compacted fill or clay that moves seasonally, the bottom blocks take uneven point loads and crack at the corners. We see this most often in Dallas neighborhoods where retaining walls were built decades ago as afterthoughts, often with no drainage aggregate behind them. Water builds up in the clay, freezes rarely but expands, and the pressure finds the weakest point in the wall.
Unilock Parts & Our Repair-vs-Replace Approach
When a Unilock paver fails, the first question is always whether you can still get the matching unit. We use genuine Unilock replacement units whenever possible to match color, texture, and dimension. A Brussels Block paver from 2010 isn’t the same as one poured last year, even in the same color family. Pigments drift. Molds wear. We account for that. For discontinued lines where genuine units aren’t available, we source high-quality compatible pavers from local Dallas suppliers and blend them so the repair doesn’t look like a patch.
But here’s the conversation we have more often than you’d think: if the base or drainage is failing, replacing just the surface units is a waste of your money. A new layer of pavers on a bad bed will fail again within two to three Dallas summers. That’s not opinion; it’s what we’ve seen on job sites across the city. We’ll tell you honestly whether a spot repair holds or whether the base needs rebuilding. If the base is sound and a few units are damaged, we replace them and you’re done. If the base is moving, we repair the base first, then the surface. That honest call is why our written price comes before the work, not after we’ve opened things up and found what we expected to find. Call (940) 204-5368 and we’ll walk you through what your specific situation calls for.
Our Unilock Service Process – Step by Step
We work a straight process on every Unilock service in Plano and Dallas, whether it’s a full paver driveway installation or a repair on an existing patio. No mystery, no surprises. Here’s how it goes.
- 1
Diagnosis: We inspect the full installation, not just the visible damage. That means checking the base depth, looking at drainage patterns, evaluating edge restraint, and identifying whether the subgrade is clay and moving. On a recent job in Richardson, we reset a 750-square-foot Unilock Brussels Block driveway after the original base washed out under heavy rain. Our crew pulled the pavers, replaced the failing sand, and added a new compacted aggregate base; the original installer had skipped that step entirely, and the customer’s driveway was sinking within a year.
- 2
Repair or install: For repairs, we remove the affected units, correct the underlying cause, and reinstall with fresh Edge Restraint and sand. For new installations, we compact the base in lifts, run proper drainage, and lay units with consistent joint spacing before compaction.
- 3
Test and verify: We check joint stability, surface drainage, and edge restraint before we call the job done. If we find a problem during testing, we fix it before we tell you it’s finished.
- 4
Documentation and warranty: Every job comes with the written 365-Day Done Right Promise. If something fails inside the guarantee window, Penhallow Remodeling Dallas comes back and fixes it at no charge, including a free second visit, no service call fee, no re-inspection fee. That’s the Kingswell standard.

AfterUnilock Products We Service & Install in Dallas
We service and install the full range of Unilock hardscape products across Dallas, including the lines we see most often in local installations. Brussels Block is the most common driveway and walkway product we service, with the distinctive rounded edges and the spalling issues Dallas clay causes. Richcliff shows up frequently on patios and pool surrounds, where its textured face holds moisture and requires sealing discipline. Town Hall appears in larger driveway applications where base compaction matters more than anything. Estate Wall is the retaining wall block we rebuild most often, especially on older Dallas properties where original drainage was never installed. We also work with other Unilock lines, including wet cast products and permeable pavers, and we keep common replacement units and sand supplies in stock locally for faster turnaround.
We Also Service These Brands
Unilock is one of the brands we work with, but it’s not the only one. Penhallow Remodeling Dallas offers General Contractor services as a multi-brand contractor, and we bring the same written-price, written-guarantee standard to every job, whether it’s a KraftMaid kitchen remodel, Cambria or Silestone countertop installation, or a Kohler bathroom fixture upgrade. Our experience with multiple trade brands means we’re not locked into one product family or one way of working. We recommend what fits your project, even if that recommendation is a different brand than Unilock.
FAQs – Unilock Construction Service in Dallas
Can I add a new section to my existing Unilock Brussels Block patio and match the color?
Color matching an existing Brussels Block patio is possible, but it requires care. Sun exposure ages paver pigments over time, so a newly poured unit in the same color family will look brighter than your installed pavers. We source genuine Unilock units and can shift the blend to account for fading, but the honest answer is that a perfect match on a patio that’s five or more years old is difficult. What usually works better is adding a border or band with intentional contrast; that reads as a design choice rather than a patch. Call (940) 204-5368 and we’ll tell you what’s realistic for your specific patio.
Why are my Unilock Estate Wall blocks cracking at the corners near the bottom?
Estate Wall blocks crack at the bottom corners when the base course is unevenly supported, usually because the original installer didn’t compact the foundation material properly or there’s water expanding in the clay behind the wall. Dallas’s expansive blackland prairie clay swells when wet and shrinks when dry, creating uneven loads on the wall base. The bottom blocks carry the entire weight of the wall plus the soil pressure behind it, so they crack first. The fix is rebuilding the affected section with a properly compacted base and proper drainage aggregate behind the wall. Call (940) 204-5368 and we’ll diagnose it before you decide anything.
How do you fix Unilock pavers that have sunk in the middle of a Dallas driveway?
Sinking pavers in the middle of a driveway happen when the base underneath isn’t compacted correctly for Dallas clay. The pavers themselves are almost never the problem. We pull the affected section, rebuild the base with properly compacted aggregate, address any drainage issues, and reinstall the pavers with fresh sand and edge restraint. If the base has washed out from poor drainage, we correct that first. A patch on top of a moving base will sink again within a few summers. For an exact quote on your driveway, call (940) 204-5368. Estimates are free and the price you get in writing is the price you’ll pay.
Is it worth having my old Unilock Richcliff patio sealed every year in Dallas?
Annual sealing is not necessary for most Richcliff patios, but periodic sealing absolutely extends the life of the color and surface finish in Dallas’s intense UV. The bigger issue is what’s causing the surface to hold moisture. If sprinkler runoff is soaking the patio repeatedly, you’ll get efflorescence and surface staining whether you seal or not. We recommend correcting drainage first, then sealing every two to three years depending on exposure. If your patio faces full afternoon sun and you want the color to hold, a quality sealer every two years is worth the cost. For an exact recommendation, call (940) 204-5368 and we’ll take a look.
Can you repair a Unilock retaining wall that’s bowing out over my driveway?
Yes, a bowing Unilock retaining wall can be repaired, but it needs to be diagnosed correctly. A bow usually means water is building up behind the wall because there’s no drainage aggregate or weep holes, and that hydrostatic pressure is pushing the blocks forward. We remove the affected section, install proper drainage behind the wall, rebuild the base if needed, and reset the blocks. In some cases, when the wall is severely bowed or the blocks are fractured, replacement of that section is the safer option. Call (940) 204-5368 and we’ll tell you which approach your wall needs.
How much does Unilock construction cost in Dallas?
Pricing depends on scope, access, and what’s underneath the surface. Here are the ranges we see most often in the Dallas market.
| Service | Price Range |
|---|---|
| Paver Driveway Installation | $7,000 – $18,000 |
| Driveway Replacement | $5,000 – $14,000 |
| Paver Patio Installation | $3,500 – $11,000 |
These ranges reflect what we’ve priced and built in Dallas over the years. A paver driveway replacement on a standard two-car driveway with good access lands lower in the range; a larger driveway with failing base, drainage correction, or premium paver selection lands higher. You’ll get an exact written price before any work starts, and that number doesn’t change once we begin. Call (940) 204-5368 to schedule your free estimate.
