Unilock Construction in Chatsworth, CA | Elmstead Remodeling Santa Clarita
We provide independent Unilock hardscape installation and repair across Chatsworth, from paver driveways on ranch properties to wall systems along equestrian fencing. What makes our Unilock work different here is that we plan for the expansive clay soils and 100°F-plus summer swings that are part of living in the northwest San Fernando Valley. If you’re pricing a new paver driveway or trying to figure out why your existing patio is separating at the joints, call (661) 542-4056 for a written estimate before any work starts.
Why Chatsworth Residents Choose Us for Unilock Service
We work on Unilock hardscapes across Santa Clarita and the San Fernando Valley, and as a General Contractor in Chatsworth, we’ve learned how their modular systems behave on the expansive soils and heat cycles specific to Chatsworth ranch properties. That means we diagnose and build around real site conditions instead of just swapping pavers and hoping for the best. Graham Stein, our owner, picked up the fundamentals of construction at Los Angeles Trade-Technical College and spent the better part of two decades swinging a hammer on projects across Southern California. He and the crew have worked steadily throughout the area, building a reputation on jobs where the written price doesn’t change and the drop cloths come out before anything else.
We’re an independent Unilock service provider. We are not manufacturer-affiliated or authorized, which means our recommendations about parts and repair strategy are based on what holds up in Chatsworth’s specific conditions, not on what a distributor wants moved this quarter. For OEM versus aftermarket choices, we tell you exactly what we’d use on our own equipment. More on that below.

Common Unilock Construction Problems We Solve in Chatsworth
- Thermal heaving and joint widening on paver driveways. Chatsworth summers routinely push past 100°F and Santa Ana winds drive dust and dry heat across the valley. On older ranch lots with unamended clay soils, those temperature swings make pavers expand and contract hard. We see Town Hall driveways where the joints have opened up an extra quarter inch in a single season, letting sand wash out and leaving units to shift under vehicle weight.
- Edge restraint failure on equestrian properties. The original plastic edging on many older Unilock installations rots or shifts over time. On properties with horse facilities, the added vibration from hoof traffic makes it fail faster. Once the edge lets go, Town Hall pavers drift into the gravel base and the whole border starts to wander. We replace that plastic with aluminum edging rated for the load.
- Efflorescence bloom on Richcliff pavers in shaded courtyards. White mineral deposits show up when water moves through the paver and evaporates at the surface. In Chatsworth, we see this most in courtyards shaded by mature oaks or near unsealed retaining walls, where irrigation overspray from horse wash racks keeps the pavers damp. The fix is often a drainage correction and a proper sealer, not just scrubbing the surface.
- Warped or cracked U-Cara wall caps on south-facing property lines. U-Cara Multi-Face Wall System caps take direct sun on south exposures. When the original install left no expansion gaps, the caps warp or crack within a few summers. We reset the wall section with proper gap spacing and matching units.
- Washed-out base material on older Brussels Block drives. Decades of Santa Ana-driven dust and occasional heavy rain can wash the sand bed out from under older paver installations. The pavers tilt, the surface gets wavy, and drainage stops working. We re-grade the base, add geotextile where needed, and reinstall the pavers with clean bedding sand.
Unilock Service in Chatsworth: What Local Conditions Mean for Your Equipment
Chatsworth’s unincorporated status means many ranch properties still rely on county permitting rather than city. That’s not a bureaucratic footnote; it changes what you can build and what it costs. Hardscape projects that add permeable pavers can qualify for LA County’s stormwater infiltration credits, which is a real financial offset never offered a few miles away in incorporated Canoga Park. For Unilock owners, this means a paver patio or driveway replacement isn’t just a cosmetic upgrade. It can be a county-blessed stormwater improvement that reduces runoff into the local watershed. We’ve helped property owners along Valley Circle Boulevard and throughout the equestrian pockets of northwest Chatsworth plan projects that meet county standards while using Unilock units rated for vehicular and hoof traffic. The credits don’t show up on every project, but when they do, they’re worth knowing about before you finalize your scope of work.
Unilock Models & Products We Service in Chatsworth
We install and repair the Unilock lines most common in the San Fernando Valley: Town Hall for driveways and walkways, Brussels Block for older ranch-style entries, Richcliff for a more contemporary patio look, and U-Cara Multi-Face Wall System for retaining and seat walls. When matching color and texture matters, especially on odd lots from older Town Hall drives, we use genuine Unilock replacement units. For sub-base and edge restraints, we spec higher-quality aftermarket geotextile and aluminum edging that outperform the original plastic. If more than 15 percent of a patio is damaged, we typically recommend resetting the entire section rather than piecemeal patching, because the color fade difference between old and new units will be visible forever. We keep common Town Hall and Brussels Block units and aluminum edging on the truck or readily available for fast Chatsworth turnaround.

AfterUnilock Service Pricing in Chatsworth
Every Unilock project starts with a written price before any work begins. That’s not a marketing line; it’s the way we run every job in Chatsworth and across the valley. The price on the paper is the price on the invoice, and we put that in writing before the first board goes down. What drives cost is site access, drainage corrections, the condition of the existing sub-base, and how much of the old installation needs to come out. A free estimate includes a walkthrough, a line-by-line scope, and a hard number, not a range that grows after the crew arrives.
| Service | Price Range |
|---|---|
| Paver Driveway Installation | $7,000 – $18,000 |
| Paver Patio Installation | $3,500 – $11,000 |
| Driveway Replacement | $5,000 – $14,000 |
These ranges reflect typical Chatsworth ranch properties with half-acre or larger lots and driveway runs measured in the tens of feet, not the hundreds. For an exact number on your property, call (661) 542-4056. Estimates are free and the number we give you is the number you’ll see on the invoice.

FAQs – Unilock Construction in Chatsworth
Chatsworth’s clay soils expand and contract with moisture changes, and when summer temperatures push past 100°F for days at a time, the pavers themselves expand. With unamended clay beneath the base and no expansion allowance at the edges, the units push against each other and the joints widen. The fix is a properly compacted base, the right joint sand, and edge restraint that actually holds. Call (661) 542-4056 if your joints are opening up; we’ll tell you whether a reset is worth it before you spend a dollar.
Usually not for a paver patio on grade, but it depends on the scope. If the patio ties into a structure or if we’re altering drainage that affects a building wall, the county may want a look. For simple paver installations away from structures, the permit path is much lighter, and permeable pavers can actually work in your favor under LA County’s stormwater rules. If you’re considering a Chatsworth Bathroom Remodeling project alongside your hardscape work, we’ll coordinate the scope so both trades line up cleanly. We’ll walk you through exactly what applies before any work starts.
Town Hall and Richcliff are both rated for vehicular traffic and both can last 30-plus years with a proper base and edge restraint. The difference on a Chatsworth ranch comes down to surface texture and joint width. Town Hall has a more traditional look with tighter joints; Richcliff has a broader face and wider joints that handle thermal movement a bit more gracefully. On a south-facing driveway with no shade, Richcliff’s wider joints give the pavers more room to move in 105°F heat. Both fail early without a good base, and both hold up well when the drainage and edge restraint are done right.
Yes, we can source genuine Unilock replacement units for most current lines, but color matching on older pavers is never perfect. UV exposure fades the surface, and new units will look newer. That’s why if more than 15 percent of a patio is damaged, we recommend resetting the entire section rather than patching a few spots. The eye catches a fade difference faster than a full fresh surface. Call (661) 542-4056 and we’ll look at your existing patio in person and tell you honestly which way makes sense.
It can help with water management and soil stability, but it is not a fire barrier. Permeable pavers reduce runoff and keep ground moisture more consistent, which can help the landscape around your home stay less tinder-dry in August. What’s more directly useful for fire risk is keeping the area around the house clear of fine fuels and maintaining the hardscape as a non-combustible zone. If you’re planning a patio with fire resilience in mind, we’ll spec the right base and drainage for it. Call (661) 542-4056 and we’ll walk the site with you.

Last fall our crew reset a 1970s-era Unilock Brussels Block driveway on a horse property off Valley Circle Boulevard. The original sand bed had washed out from decades of Santa Ana-driven dust and the pavers had tilted toward the barn. We re-graded the base, installed aluminum edge restraint, and swapped in matching factory seconds where the old units had cracked. That drive now stays true under hoof and tire traffic. If your pavers are doing something similar, call (661) 542-4056 for a free estimate. We’ll give you a written price before anything goes down.
