Why Dallas Homeowners Choose Unilock Construction
Mason Remodeling Co Dallas provides Dallas Unilock service for construction, repair, and installation across Dallas, TX. We work on Unilock paver patios, driveways, retaining walls, and walkways every week, which means we know how Texas clay soil, brutal UV exposure, and sudden downpours actually stress these products over time. We’re not a manufacturer-authorized dealer, and we’re not here to push a replacement program. We’re here to fix what’s broken, match what’s already in your yard, and build new Unilock work that holds up in Dallas conditions. Call (432) 302-8761 for a written estimate on any Unilock project.
If you’re reading this, you probably already have Unilock pavers or walls on your property, or you’re about to invest in them. Unilock makes a genuinely good product. The Brussels Block, Richcliff, Beacon Hill Flagstone, and Estate Wall lines are all over Dallas, from Preston Hollow to Lakewood. But the product is only half the equation. The base underneath it, the edge restraint around it, and the joint sand between the blocks determine whether it still looks right in five years. That’s where our crew comes in.
You should know who is coming, what it costs, and what happens if something goes wrong – before we ever pick up a tool. That’s how Isaac Pruett runs this company, and it’s how every Unilock job gets handled, whether we’re repairing a sunken paver section in East Dallas or building a new driveway with our Mesquite Unilock service area.
Why Trust Mason Remodeling Co Dallas for Your Unilock Construction?
Unilock work looks simple from the outside. Blocks go on the ground, sand goes between them, done. But anyone who has pulled up a failed Dallas paver patio knows the truth: the problems are almost always underneath. Our crew has spent years diagnosing Unilock failures in this city’s specific soil conditions, and that experience changes how we approach every job.
Isaac Pruett learned construction at Los Angeles Trade-Technical College and spent years running jobs across Southern California before bringing his method to Dallas. He walks every Unilock job himself before the first block gets pulled or laid. That matters because Dallas expansive clay behaves differently than almost any other soil in the country. It swells when wet, shrinks when dry, and can shift a paver base by inches in a single season. A crew that learned pavers in Florida or Arizona doesn’t know what that means. We do.
We’re an independent Grapevine Unilock service provider. That’s worth understanding clearly. We are not affiliated with Unilock, we are not an authorized dealer, and we don’t claim to be. What we are is a crew that works with these products constantly and knows their failure modes in Dallas specifically. When a repair requires an exact color and size match, we source OEM Unilock pavers and matching joint sand. When a structural fix calls for crushed stone and geotextile, we use the same spec materials Unilock recommends, sourced from local Dallas suppliers. We never cut corners on the base, because in this soil, the base is everything.
Every job gets a written price before work starts. Every completed project carries a written guarantee with plain-language terms. And if something fails after we leave, you call us and we come back at no charge. That’s the 365-Day Done Right Promise, and it applies to Unilock work just like everything else we do.

Common Unilock Construction Problems We Fix in Dallas
- Polymeric sand breakdown in joints. Dallas sun is relentless. The intense UV exposure breaks down the polymers that bind joint sand together, and heavy spring and fall rains wash the loose material away. The result: weeds sprouting between pavers and ant colonies setting up shop in the gaps. We see this constantly on Unilock Brussels Block patios and Richcliff driveways that are three to five years old. The fix is removing the old sand, cleaning the joints properly, and reinstalling a high-quality polymeric sand rated for our climate. Skipping the cleaning step is why DIY fixes fail.
- Edge restraint failure along driveways and pool decks. Unilock pavers are held in place by a rigid edge restraint system, usually aluminum or plastic, pinned into the base. When that restraint fails or was never installed correctly, the border pavers drift outward. You’ll notice the outside edge of your driveway developing gaps that widen over time, or a paver that’s shifted an inch out of line with its neighbor. In Dallas, repeated thermal expansion and contraction works these edges loose faster than in milder climates. We rebuild the edge with proper restraint and re-anchor the border course.
- Settling and heaving over expansive clay. This is the big one in Dallas. The region’s clay soil expands and contracts dramatically with moisture changes. A drought followed by heavy rain can lift or drop paver sections by two to three inches. Unilock Estate Wall installations on slopes are particularly vulnerable, as the wall’s drainage layer gets overwhelmed and hydrostatic pressure builds behind the blocks. When pavers settle unevenly, they create trip hazards that are a genuine liability, especially around pools and walkways. The repair often involves pulling the affected area, rebuilding the base with properly compacted crushed stone, and relaying the original pavers. If the color hasn’t faded, the result is invisible.
- Efflorescence on dark Unilock colors. If you chose Unilock pavers in Basalt or Coal, you may have noticed a white, chalky film developing after a few humid months. That’s efflorescence, a mineral deposit that wicks up through the paver as moisture evaporates. It’s cosmetic, not structural, but it’s ugly on dark pavers. Dallas’s humid summers make it more pronounced than in drier climates. We can clean it with efflorescence removers and help you understand what’s normal versus what indicates a drainage problem underneath.
- Drainage failure behind retaining walls. Unilock Estate Wall blocks are designed to work with a proper drainage system: gravel backfill, a perforated pipe, and a geotextile separation layer. When that system is skipped, shortcutted, or clogged, water pressure builds behind the wall. Over time, the wall leans forward or the top course begins to separate. In Dallas, a wet spring after a dry winter is exactly when these failures show up. We rebuild the wall section with the drainage system done correctly, because patching the face without fixing the drainage is a temporary fix.
Unilock Parts & Our Repair-vs-Replace Approach
Here’s a conversation we have regularly in Dallas. A homeowner calls us about a paver patio with a few cracked border units and a small depression. Another contractor told them the whole patio needs to come out. The quote is five figures. They want a second opinion.
Our answer depends on what’s underneath. If the base is still sound, which means it was compacted correctly in the first place and the drainage is working, we repair. We pull the cracked pavers, check the bedding layer, and relay the section with matching OEM Unilock pavers and fresh joint sand. The color match has to be exact, and with Unilock’s consistent manufacturing, we can usually get it done without a visible patch line. Replacing an entire patio for a few cracked border units is often unnecessary cost, and we’re not interested in selling you work you don’t need.
If the base has failed, which we diagnose by lifting pavers and checking for voids, organic material, or insufficient compaction, then repair means rebuilding the section properly. That means excavation to the right depth, a geotextile layer, compacted crushed stone in lifts, and a fresh bedding layer. We stock common Unilock pavers in our Dallas yard and source less common colors and profiles from local suppliers, usually within a few days.
For structural elements like retaining walls, we use OEM Unilock blocks but pair them with high-quality drainage materials from Dallas suppliers. The spec is what matters, and we follow Unilock’s published installation guidelines regardless of who manufactures the gravel or pipe. If you’re weighing repair against replacement, call (432) 302-8761. We’ll give you our honest read and a written price either way.
Our Unilock Service Process – Step by Step
- 1
Site evaluation and diagnosis. We walk the entire area, not just the visible problem. Unilock failures often start at the edges, under downspouts, or where the grade changes. We check for base voids, edge restraint condition, drainage patterns, and signs of clay movement. You get a written diagnosis with photos.
- 2
Written estimate with line items. Before any work starts, you receive a written price covering materials, labor, and any required base rebuild. No verbal numbers, no change orders unless the scope changes by mutual agreement. The price you sign is the price you pay.
- 3
Repair or installation. For repairs, we remove only what’s necessary. Damaged pavers come out, the base gets inspected and rebuilt if needed, and the original or replacement pavers go back in with proper edge restraint and joint sand. For new installations, we build from the ground up: excavation, geotextile, compacted base, bedding layer, pavers, edge restraint, joint sand.
- 4
Testing and finish. We run water across the surface to confirm drainage, walk every joint to check stability, and clean the area before we leave. You’ll see the finished work and we’ll walk it with you before we consider the job done.
- 5
Written warranty and follow-up. Every Unilock job carries our written guarantee, which covers workmanship for 365 days from the completion date. If something shifts or fails within that window, call us. We come back at no charge.

AfterUnilock Products We Service & Install in Dallas
Our crew works with the full range of Unilock products commonly installed across Dallas. That includes the Brussels Block, a tumbled paver with an old-world look that’s extremely popular for patios and walkways in older East Dallas neighborhoods. We also handle Richcliff, a larger-format paver with a more contemporary profile that shows up frequently in newer Preston Hollow and North Dallas developments. For natural stone aesthetics, we service and install Beacon Hill Flagstone, which mimics the irregularity of real flagstone with the consistency of manufactured concrete. On the wall side, we build and repair Estate Wall systems, including corners and caps, with a focus on drainage that actually works in Dallas clay. We stock common colors locally and order specialty profiles as needed.
We Also Service These Brands
Unilock is one of several specification-grade brands we work with across our General Contractor services and hardscaping projects. If your project involves other elements, whether it’s KraftMaid cabinetry, Cambria or Silestone countertops, or Kohler fixtures, the same written-price, verified-crew standard applies. One company, one standard, no surprises.
FAQs – Unilock Construction Service in Dallas
Yes, in most cases. Unilock’s manufacturing process produces consistent color across production runs, and we source OEM pavers in the same color and profile as your existing installation. We can also pull pavers from a less visible area of your patio, like under a grill or planter, to use in the visible repair zone, then place the new pavers in the hidden spot. That guarantees a perfect match. Call (432) 302-8761 for a written quote on your repair.
Ants and weeds in paver joints almost always indicate the polymeric sand has failed or was never installed correctly. Dallas UV exposure breaks down the polymer binders faster than in many other climates, and once the sand becomes loose and granular, ants can tunnel through it and weed seeds can take root. The fix is removing the old sand, thoroughly cleaning the joints, and reinstalling a high-quality polymeric joint sand rated for our sun and rain conditions. If it’s happening only a year in, the original installation likely used a low-grade sand or skipped the joint cleaning step.
Unilock uses integral color pigments in the concrete mix, not surface-applied dyes, so the color runs through the full depth of the paver. They resist fading much better than stained or painted concrete. However, prolonged UV exposure does gradually soften the color, particularly on darker tones, and you may notice slight variation between sun-exposed and shaded areas after many years. This is normal and generally even across the surface. A proper sealant can slow the process if you want to preserve the original look longer.
Almost never. A leaning Unilock Estate Wall is nearly always a drainage failure, not a block failure. The wall needs a gravel drainage layer, a perforated pipe at the base, and a geotextile separation fabric between the soil and the drainage material. If any of those elements is missing or clogged, water pressure builds behind the wall and pushes it forward. The repair involves rebuilding the affected section with the drainage system done correctly. Patching the face of the wall without fixing the drainage will fail again, often within the same year.
Technically possible, but rarely the right approach in Dallas. Our expansive clay soil shifts constantly, and if the concrete slab underneath is cracked or moving, laying pavers on top will just transfer those movements through to the surface. The pavers will crack and settle along the underlying slab’s fault lines. The proper method is removing the slab, preparing a compacted base that can handle Dallas’s soil movement, and installing the pavers correctly. It costs more upfront, but it’s the difference between a driveway that lasts 20 years and one that needs repair in three. Call (432) 302-8761 for a written estimate on your specific driveway.
Unilock paver patio installation in Dallas typically ranges from $3,500 to $11,000 depending on size, site prep, and paver profile. A paver driveway runs $7,000 to $18,000, and full driveway replacement including removal of the existing surface lands between $5,000 and $14,000. These are real ranges for our market, not national averages. Your exact price depends on what’s underneath the surface and what needs to come out first. Call (432) 302-8761 and we’ll give you a written line-item quote so you know exactly what you’re paying for.
