Unilock Construction in The Woodlands, TX | Penhallow Remodeling Houston
We install and repair our Unilock services, including pavers, walls, and driveways throughout The Woodlands. What sets our Unilock work here apart is simple: we build every project around The Woodlands’ tree preservation rules and expansive clay soils, not around a generic installation template. If you need Unilock hardscape work done right in The Woodlands, call Penhallow Remodeling Houston at (254) 527-5340 for a free estimate.
Trevor Nash and our crew have been working with Unilock products long enough to know where they shine and where they fail in this climate. We’re an independent contractor, not a manufacturer affiliate. That means we recommend what actually works for your yard, not what a corporate catalog tells us to push.
Why The Woodlands Residents Choose Us for Unilock Service

Most contractors in The Woodlands can lay pavers. Far fewer understand how Unilock’s specific product lines behave under our local conditions. We do. Trevor studied construction technology at Los Angeles Trade-Technical College before spending years on everything from tract homes to full gut renovations, and that training shows in how we approach paver work: base preparation first, drainage second, aesthetics third. You’d be surprised how many crews reverse that order.
We’re a General Contractor in The Woodlands and a local Unilock service provider with a straightforward approach. We use OEM Unilock pavers and walls when matching existing color and texture is critical, especially for EnduraColor blends that have faded under years of Texas sun. Where aftermarket base and jointing materials outperform OEM for our soil conditions, we use those instead and tell you why. The written price you get before work starts is the price on the final invoice. That’s the Kingswell standard we’ve operated under since 2004.
Every technician who walks onto your property is background-checked and in uniform. A live person answers our phone 24/7, not a voicemail prompt. And every Unilock project carries our 365-Day Done Right Promise: if something fails within the guarantee period, we come back and fix it at no charge, in writing.

Common Unilock Construction Problems We Solve in The Woodlands
Unilock products are well made, but The Woodlands tests them hard. Here are the failure modes we see most often, and what’s behind each one:
- Efflorescence on EnduraColor pavers. The Woodlands’ humid summers mean repeated wet-dry cycles. Water wicks through the paver, carries minerals to the surface, and leaves that chalky white residue. We clean it properly and, more importantly, address the drainage issue that keeps feeding it.
- Settlement and edge shifting on paver patios. Our expansive clay soils swell when wet and shrink when dry. Add root pressure from mature pines and oaks, and pavers start to sink or drift within a few seasons. A properly compacted base with geogrid reinforcement prevents most of this.
- Weed and ant intrusion through polymeric sand joints. Heavy rainstorms overwhelm drainage and wash out joint sand. Ants and weeds move in fast. We re-joint with an aftermarket polymeric sand blended for high-rainfall climates, which holds up better than what many pavers ship with.
- Color fading on Brussels Block in south-facing areas. Intense summer sun in The Woodlands bleaches darker pavers faster than most homeowners expect. We match replacement pavers to the existing faded tone rather than the original factory color, so repairs don’t look like patches.
- Leaning Unilock retaining walls. Clay soil expansion pushes against walls from behind, especially when drainage wasn’t installed correctly the first time. We rebuild with proper gravel backfill, weep holes, and sometimes geogrid reinforcement tied into the slope.
Unilock Service in The Woodlands: What Local Conditions Mean for Your Equipment

Here’s something most Houston-area contractors don’t deal with, and it changes how Unilock work gets done in The Woodlands: many villages require a permit and a tree protection plan before any hardscape work happens within the drip line of a protected pine or oak. That means paver layouts often need root-bridge designs or shallow-base construction. You can’t just dig down 8 inches everywhere and call it a day. A root bridge spans over major roots instead of cutting through them, and shallow-base construction uses a reduced excavation depth with a compacted aggregate layer that won’t suffocate the tree. These techniques protect both the tree and your pavers.
This matters for Unilock owners specifically. A standard paver installation in Katy or Tomball might never encounter a single protected tree. In the Village of Cochran’s Crossing or Grogan’s Mill, nearly every backyard has mature pines within 20 feet of the patio. On a Richcliff paver patio in Cochran’s Crossing, our crew found a 12-by-14-foot section had settled 3 inches where a mature loblolly pine’s roots were drawing moisture from the clay. We excavated without cutting any root over 2 inches, installed a compacted aggregate base with geogrid, and relayed the pavers to match the original pattern. The patio is now level and the tree is untouched. That’s the kind of work this township demands, and it’s exactly the kind of work we’ve built our process around.
The Woodlands was developed under strict, tree-preserving standards set by The Woodlands Development Company. Unlike most Houston suburbs, builders here navigate restrictive covenants and architectural review that influence everything from foundation design to exterior materials. Unilock hardscape work falls under that same umbrella. A paver driveway or patio that looks beautiful but kills a 40-year-old oak will not pass village review. We design around the trees, not through them.
Unilock Models & Products We Service in The Woodlands
Our crews work with the full range of Unilock product lines common to The Woodlands homes. That includes the EnduraColor series (Elegance, Richcliff, Thornbury) for upscale patios and pool decks, Brussels Block for driveways and walkways, and Ledgestone for retaining walls and vertical features. We keep a small inventory of current-production pavers locally for fast turnaround on repairs, and we order OEM Unilock pavers directly when matching older or discontinued blends. For complete Unilock sales and service, or if you need our Bathroom Remodeling in The Woodlands, we’re your independent local resource.
When a client asks whether to patch or replace, we’re honest. Small, isolated damage can often be spot-repaired with matching pavers. But large sun-faded sections or widespread settlement usually look better with selective replacement of the affected area. Patching a 10-year-old Brussels Block driveway one paver at a time leaves a patchwork that draws more attention than the damage did.

What drives the number up or down? Square footage is the biggest factor. So is base preparation. In The Woodlands, where expansive clay and tree roots are common, a proper base with geogrid and drainage costs more than a thin gravel layer, but it’s what keeps the pavers flat for 20 years. If root-bridge construction is required, that adds some cost. So do complex patterns, borders, and curves.

FAQs – Unilock Construction in The Woodlands
Yes, in most cases. Sun and rain in The Woodlands fade pavers at a predictable rate, so we match replacement pavers to the existing faded tone rather than the factory-fresh color. For EnduraColor blends especially, we order OEM Unilock pavers and sometimes blend in a slightly different production lot to create a seamless repair. If you send us a photo and the approximate install year, we can usually tell you before the visit whether a true match is feasible. Call (254) 527-5340 and we’ll take a look.
We design around the roots. The Woodlands requires tree protection plans for hardscape work within the drip line of protected trees, so we use root-bridge construction or shallow-base techniques that avoid cutting roots over 2 inches in diameter. That keeps the tree healthy and keeps your patio from settling later, because cutting a major root destabilizes both the tree and the ground under your pavers. As independent contractors, we’ve done enough of these in villages like Cochran’s Crossing and Indian Springs to know what passes review.
Sealing is optional, but it helps. The Woodlands’ humidity and heavy rainfall accelerate efflorescence and algae growth on unsealed pavers, especially in shaded areas. A quality penetrating sealer also slows color fading from our intense summer sun. We don’t push sealing as mandatory, but for driveways in full sun or under heavy tree canopy, we often recommend it as part of the installation. We’ll include it as a separate line item with its own price, so you decide.
Lighter colors in the Unilock EnduraColor line, like lighter Thornbury or Elegance blends, stay noticeably cooler underfoot than darker Brussels Block or charcoal tones. EnduraColor also resists fading better than standard pavers, which matters for a pool deck that takes direct sun all afternoon. We’ve installed enough pool surrounds across The Woodlands to know that surface temperature matters more than most people expect. Schedule a free estimate at (254) 527-5340 and we’ll bring samples you can actually stand on in the sun.
Yes, and this is one of our most common repairs. Clay soil in The Woodlands swells when wet and pushes against the back of retaining walls, especially when the original install skipped proper drainage. We excavate behind the wall, install gravel backfill and a drainage pipe, reset or replace the wall blocks, and often add geogrid reinforcement tied into the slope. If the blocks are intact, we reuse them. If they’re cracked or severely displaced, we order matching Unilock Ledgestone or whatever line was originally used.
