Why Los Angeles Homeowners Choose Unilock Construction
We provide independent Unilock construction service across Los Angeles, from paver driveway installations in the Hollywood Hills to patio repairs in Mar Vista. Our crew has installed and repaired Unilock pavers throughout the Basin for over a decade, and we track how EnduraColor and Richcliff products actually hold up under L.A.’s specific sun, drought, and soil movement conditions. As an independent Unilock service provider, not factory-authorized, we give straight answers on when a paver can be salvaged versus replaced, without warranty pressure. Call (213) 277-6578 to talk through your project.
If you’ve got a Unilock patio that’s settling, a driveway with fading pavers, or joint sand washing out after every rain, you already know the factory brochure won’t tell you what’s actually happening under your feet. That’s where we come in. Trevor Nash, our owner, grew up in the Crenshaw district watching his uncle patch drywall and re-frame doorways in the bungalows nearby, and he studied construction technology at Los Angeles Trade-Technical College before spending two decades working residential and light commercial jobs across the Basin. He’ll give you a number first, then pick up the tools.
Why Trust Penhallow Remodeling Los Angeles for Your Unilock Construction?
Unilock pavers are a specific animal. They’re not poured concrete, and they’re not thin-set tile. The base matters more than the paver, the joint sand matters more than the pattern, and the way water moves through and around the whole system determines whether you’re calling us back in three years or fifteen. Our technicians have worked with Unilock EnduraColor, Richcliff, Town Hall, and Promenade lines long enough to know what each one does when L.A. throws UV, hard water, and expansive clay soil at it.
We stock genuine Unilock EnduraColor pavers locally for color-matched partial replacements, because when you only need twelve pavers to patch a section, aftermarket options won’t match the surface texture and the color will drift within two summers. For base material and joint sand, we lean on high-quality poly sand and aggregate that handle Los Angeles drainage conditions better than what comes off the factory pallet. The poly sand we use resists the mineral-rich irrigation water that breaks down standard joint material in this city.
Trevor still lives a few miles from where he grew up. He knows which neighborhoods sit on expansive clay and which ones drain toward the foundation. That local knowledge changes how we prep a base, where we add drainage, and how we compact the subgrade. It’s the difference between a patio that looks great for one season and one that stays level through five Santa Ana seasons.

Common Unilock Construction Problems We Fix in Los Angeles
- Efflorescence on EnduraColor and Richcliff pavers. That white chalky film isn’t a manufacturing defect, it’s mineral salts from L.A.’s hard irrigation water wicking up through the paver and crystallizing on the surface. We see it constantly in neighborhoods where homeowners run sprinkler systems on recycled municipal water. The fix is a proper cleaning protocol and, where warranted, a breathable sealer that lets moisture escape without trapping the salts underneath.
- Fading and color washout on older Town Hall and Promenade pavers. Los Angeles gets roughly 284 sunny days a year, and the UV exposure breaks down pigment over time. Town Hall pavers from the early 2000s are especially prone to turning chalky-beige, even when the original color was a rich charcoal. Replacing a few faded pavers won’t solve the problem if the rest of the field has aged differently, so we’ll tell you honestly whether spot replacement will look right or whether a full color refresh makes more sense.
- Joint sand loss between pavers on sloped L.A. properties. Heavy rainfall, poor drainage, and steep lots in areas like Echo Park and Silver Lake wash joint sand out faster than most homeowners expect. Once the sand goes, pavers start shifting, then edges chip, and the problem compounds. We re-sand with high-quality poly sand that resists runoff better than standard silica sand, and we’ll talk to you about fixing the drainage that caused the loss in the first place.
- Settling and heaving of paver base from expansive clay soil and seismic activity. Los Angeles sits on some of the most reactive soil in the country. Clay expands when wet and contracts when dry, and over a decade of wet winters and dry summers, a paver base can move enough to create visible dips, humps, and cracks. Add in the seismic shifting we experience, and even well-built paver installations can develop movement. We diagnose whether the movement is cosmetic or structural, then tell you what it’ll take to fix it properly.
- Tree root damage under paver driveways. Ficus roots, magnolia roots, and mature oak roots all push up against paver bases in this city. The pavers themselves rarely break from root pressure, but the base underneath gets disrupted and the surface starts to crown or dip. We lift the affected section, stabilize the root zone, and rebuild the base so the driveway doesn’t turn into a washboard within eighteen months.
Unilock Parts & Our Repair-vs-Replace Approach
Here’s the honest math on Unilock repair in Los Angeles versus replacement. If structural movement is under one inch and the pavers themselves are intact, we recommend repair. Lifting, re-compacting the base, and re-sanding usually brings the surface back to level and saves you thousands compared to tearing everything out. If movement is over an inch, or the pavers are cracked through body and not just chipped at the edge, replacement of the affected section (or the whole field) is the better long-term play.
For parts, we use genuine Unilock pavers when we’re doing partial replacements where color and texture need to match the existing field, especially with EnduraColor finishes. The factory surface texture is difficult to replicate with aftermarket products, and a mismatched paver stands out like a sore, expensive thumb. For joint sand and base aggregate, we specify poly sand and compacted gravel that outperform what the factory sells. The poly sand we use locks together when wet, resists the mineral-laden irrigation water in L.A., and stays in place through the kind of runoff that follows a strong winter storm.

Our Unilock Service Process – Step by Step
- 1
Diagnosis. We walk the site with you, check the base condition, the joint sand, the drainage, and the pavers themselves. Trevor will point out what’s failing and why. No charge for the visit, and you get a written diagnosis of what we find.
- 2
Repair or installation plan. We write up a scope of work with a fixed price. The number we hand you is the number on the invoice. If we’re replacing pavers, we’ll confirm we can source a genuine Unilock color match before we commit to the job.
- 3
Base and drainage work. For repairs, we lift the affected pavers, re-compact or replace the base, and add drainage where the water is causing the problem. For new installations, we build the base from subgrade up, compacted in lifts, with the slope set for L.A.’s rainfall patterns.
- 4
Paver install and joint sand. We reset or install the pavers, then sweep in poly sand and compact everything so the joints are full and tight. We’ll walk you through curing time and what to expect as the sand locks in.
- 5
Test and warranty. We check the surface for level, make sure water is moving where it should, and review the written guarantee with you. Every Unilock job carries the 365-Day Done Right Promise in writing: if it fails inside the guarantee period, we come back and fix it at no charge.

AfterUnilock Products We Service & Install in Los Angeles
We install and repair the full Unilock residential paver range: EnduraColor, including the Umbriano and Courtstone lines; Richcliff; Town Hall; and Promenade. EnduraColor pavers have a factory-applied color layer that’s denser and more resistant to fading than older generation products, and we stock a working inventory of common EnduraColor colors for partial replacements in L.A. driveways and patios. Richcliff pavers give that weathered stone look with better through-body color consistency. We’ll source whatever you need for the job, and we’ll tell you ahead of time if a specific color or series is back-ordered before you commit to the wait.
We Also Service These Brands
While Unilock is a big part of what we do, we’re not a one-trick shop-we also provide General Contractor services. Penhallow Remodeling Los Angeles also installs and services KraftMaid cabinetry, Cambria and Silestone countertops, and Kohler fixtures across full kitchen and bath remodels. If your project spreads beyond the patio, we’re equipped to handle the whole thing under one written price.
FAQs – Unilock Construction Service in Los Angeles
No. We are an independent Unilock service provider. That means we’re not bound by factory sales quotas or warranty-claim targets, so when we tell you a paver can be salvaged, we mean it structurally, not as a way to avoid filing paperwork. We install and repair Unilock products because they’re good products, and we service them because we know how they fail in Los Angeles conditions. Call (213) 277-6578 for a straight answer on your specific situation.
Yes, for partial paver replacements where color and surface texture need to match the existing field, especially with EnduraColor products. For base material and joint sand, we use high-quality poly sand and compacted aggregate that hold up better in L.A.’s hard water and heavy runoff conditions than factory-sold alternatives. We’ll explain which we’re using and why on every job, and it’s all in the written scope of work before we start.
Small repairs, like re-sanding joints or replacing a handful of pavers, are usually done in a single day. A full paver driveway repair with base rebuild and tree root stabilization typically takes three to five days. New paver patio installations in Los Angeles usually run five to ten days depending on the size, access, and how much base preparation the site needs. We’ll give you a written timeline with the written price, and we show up in the window we gave you.
We service and install the full residential line: EnduraColor, including the Umbriano and Courtstone series; Richcliff; Town Hall; and Promenade. Most of what we see in Unilock in Santa Monica and across Los Angeles is EnduraColor on newer driveways and patios, and older Town Hall or Promenade from installations that went in fifteen to twenty years ago. Each line has its own failure profile under L.A. sun, water, and soil, and we’ll tell you what to expect from yours.
Here’s the practical answer. If you’re under a Unilock factory or installer warranty, we’ll work within its terms. As an independent provider, we can’t file claims on your behalf, but we’ll document the repair, photograph what we find, and use genuine Unilock pavers for replacement so the work doesn’t create a warranty problem downstream. Our own work carries the 365-Day Done Right Promise in writing, which covers the repair or installation we perform. If the work fails inside the guarantee period, we come back and fix it at no charge. Call (213) 277-6578 and we’ll walk you through what your warranty covers in plain English.

That white film is efflorescence, and it’s caused by mineral-rich irrigation water wicking up through the paver and leaving salt deposits on the surface. Los Angeles municipal water and recycled irrigation water carry high dissolved mineral loads, and the combination of hard water plus our dry, rapid-evaporation climate makes efflorescence more persistent here than in most other cities. We clean it with a paver-safe efflorescence remover, and where it keeps returning, we discuss a breathable sealer that slows the moisture migration without trapping salts. Call (213) 277-6578 for a free assessment.
Usually, yes. Richcliff has a consistent surface texture, so genuine Unilock replacements in the same color series blend well with the existing field. The challenge comes with age and UV fade: a Richcliff paver that’s been in the L.A. sun for eight years will have shifted color slightly from a fresh factory paver. We’ll source the closest genuine Unilock match and, where necessary, blend replacement pavers from less visible areas so the patch doesn’t read as a patch. For a free color-match assessment, call (213) 277-6578.
Joint sand loss happens when water moves across the paver surface fast enough to carry the sand with it, and that’s common on sloped L.A. lots, especially in areas like Echo Park and Silver Lake where Burbank Unilock service areas and other regions see significant runoff. Older Town Hall installations often used standard silica sand, which is too light and too loose to resist Southern California rain patterns. We re-sand with poly sand that locks together when wet, and we’ll check the slope, the drainage, and the base to make sure the water stops taking your joints with it. For a written fix plan and price, call (213) 277-6578.
It’s not something to ignore, but it’s also not unusual. The area near the garage door sees concentrated wheel load, and if the base wasn’t compacted thoroughly or drainage is pooling there, that section is the first to drop. In Los Angeles, expansive clay soil makes the problem worse: the soil swells when wet and shrinks when dry, which can create settling under any paver base. We’ll lift the affected pavers, re-compact or rebuild the base, and address the drainage so it doesn’t sink again. For a free diagnosis, call (213) 277-6578.
Yes, we seal Unilock pavers, and in Los Angeles it genuinely helps with UV fading and efflorescence. A breathable sealer designed for concrete pavers will slow the color washout that direct sun causes year after year, and it reduces the water absorption that feeds efflorescence. We don’t seal every paver job by default, because some pavers and some sites shouldn’t be sealed, but for EnduraColor and Richcliff installations in full sun, a sealer typically extends the life of the color by years. Call (213) 277-6578 and we’ll tell you honestly whether sealing your specific patio is worth it.
