Why Pasadena Homeowners Choose Unilock Construction
We provide Unilock in Pasadena, offering independent paver construction and repair service from Bungalow Heaven to the San Rafael Hills. Our crews work on Unilock driveways, patios, and pool decks weekly, and we know which lines hold up in Southern California’s heavy clay soil and how to repair settled or faded sections without tearing everything out and starting over. We are not a Unilock dealer or authorized service center. We are a Pasadena remodeling and hardscape contractor that reaches for Unilock pavers when a project calls for them, and we fix them when they fail. Call (626) 714-2992 for a free estimate.
Why Trust Elmstead Remodeling Pasadena for Your Unilock Construction?
Graham Stein, our owner, grew up in Los Angeles and learned the trade at Los Angeles Trade-Technical College before spending nearly two decades working projects across the San Gabriel Valley, including Pasadena’s Bungalow Heaven neighborhood, where older Craftsman bones require a slower hand than most crews are willing to give. That matters for paver work because Unilock pavers sit on a base, and the base is only as good as the person who compacts it. Our crews work on Unilock Beacon Hill Flagstone, Brussels Block, Richcliff, and Courtstone installations regularly enough to know how each line behaves under Pasadena sun, rain, and clay. We are an independent Unilock service provider, not an authorized one. That independence means we can be honest when a repair is smarter than a replacement, even when a replacement would put more money in our pocket. We would rather reset a paver edge correctly and hand you a written price that covers exactly that work.

Common Unilock Construction Problems We Fix in Pasadena
- Edge settling in driveways. Pasadena clay soil swells after winter rain, then shrinks in summer heat. Without a proper paver edge restraint, Unilock Brussels Block and Beacon Hill Flagstone driveways start to settle at the outside edges, leaving a visible dip where the paver meets the lawn or planter bed. We see this most often on driveways where the original installer skipped the edge restraint to save a few dollars.
- Whitish haze on Richcliff and Courtstone. Hard water from Pasadena irrigation systems leaves mineral deposits that show up as efflorescence on Unilock Richcliff and Courtstone surfaces. It looks like a white film that brushing alone will not remove. The fix is a specific cleaning process followed by re-sanding the joints, and a conversation about irrigation overspray so it does not come right back.
- Joint sand gone from leaf blowers and pressure washing. A powerful leaf blower or a strong pressure washer will strip polymeric sand from paver joints in a single season. Once the sand is gone, individual Unilock pavers start to shift and develop lippage. Our crews re-sand and recompact, then we tell you what cleaning habits will not undo the work.
- UV fading on dark-tone pavers. Pasadena gets over 280 days of sun a year. Dark-tone Unilock pavers in full sun will fade eventually, and no sealer can fully stop that. We help owners pick the right line for their exposure, and when fading has already happened, we talk through whether a partial replacement or a full color refresh makes sense.
- Cracked pavers from root growth or poor base. Tree roots from mature Pasadena oaks push up individual pavers and crack them. We repoint, replace single pavers, and where the base has truly failed, we recompact only the affected section rather than tearing out the whole patio.
Unilock Parts & Our Repair-vs-Replace Approach
When a Unilock paver cracks or settles, matching the existing color and size matters more than anything else. We source original Unilock pavers directly from local distributors whenever color and size matching is critical. For older or discontinued Unilock lines, we use high-quality aftermarket equivalents only after showing physical samples to the homeowner, side by side with the existing pavers, in daylight. We do not guess at a match. We repair individual pavers and settled sections whenever the base underneath is still sound. Replacement is only recommended when more than a third of the area is compromised, and we will show you why we reached that conclusion. If you are unsure whether your Unilock pavers can be saved, call (626) 714-2992 and we will walk the site with you.
Our Unilock Service Process – Step by Step
- 1
Site walk and honest diagnosis. We look at the base, edge restraint, drainage, and joint sand. We identify which Unilock line you have and whether the problem is the paver or what is underneath it. You get a written price before any work starts.
- 2
Repair or install. If it is a repair, we pull only the affected pavers, fix the base, reset them, and lock the edge restraint if that was the culprit. If it is an install, we excavate, compact the base in lifts, and lay the Unilock pavers to manufacturer spec.
- 3
Joint sand and compaction. Polymeric sand goes in the joints, then we run a plate compactor over the surface to lock everything together. This step is what keeps Pasadena clay from undoing the work in a year.
- 4
Clean-up and photo proof. The crew sweeps, hoses if needed, and takes a photo of the finished surface before they leave. You see the job the way we left it.
- 5
365-Day Done Right Promise. If something is not done right after the job is complete, we make it right. That promise is stamped on every project.

AfterUnilock Products We Service & Install in Pasadena
We install and repair Unilock Beacon Hill Flagstone for a more organic, irregular look, Brussels Block for classic driveways and walkways, Richcliff for a modern, tighter-jointed patio, and Courtstone for pool decks and clean-lined outdoor spaces. We keep a small stock of common joint sand, edge restraints, and base material in our Pasadena yard so repairs can start quickly. Most Unilock projects involve one of these four lines, and we know how each one behaves under Pasadena’s sun, rain, and clay soil.
We Also Service These Brands
While Unilock is a brand we reach for often, we also provide General Contractor services, so we are not a single-brand shop. Our Pasadena remodeling work also includes KraftMaid and Wellborn cabinetry, Cambria and Silestone countertops, and Kohler and Moen fixtures. The point is that our crews are comfortable across named-brand materials, and we will tell you honestly which one fits your project.
FAQs – Unilock Construction Service in Pasadena

Efflorescence on Unilock Richcliff and Courtstone pavers in Pasadena is almost always caused by hard irrigation water leaving mineral deposits on the paver surface. It can be removed with a proper paver cleaning process followed by re-sanding the joints, but if the irrigation overspray continues, the haze will return. Give us a call at (626) 714-2992 and we can assess the source before we treat the surface.
Yes, in most cases we can replace individual cracked Unilock Richcliff pavers without touching the surrounding patio. We match the color and size as closely as possible, and if the original line is still available, we source it directly from a local distributor. The larger question is whether the base under those pavers failed, and we will check that before we pull anything.
Pasadena’s clay soil expands when wet and shrinks when dry, which puts real pressure on paver edges and base material. Driveways with a properly compacted base and a locked paver edge restraint hold up well. Driveways without them settle within a few seasons. We rebuild problem sections with an engineered base and a proper edge restraint, and the difference is something you feel the first time you drive over it.
In some cases, yes, an overlay on existing concrete can work if the slab is structurally sound and the drainage is right. But many Pasadena driveways and patios have cracked concrete with poor slope, and putting pavers over that just hides the problem for a few years. We will tell you honestly whether an overlay makes sense or whether a proper base rebuild is the better use of your money. Call (626) 714-2992 for a free assessment.
For a Pasadena pool deck, we typically recommend Unilock Courtstone because its surface stays cooler under bare feet than darker, denser lines, and its lighter tones resist visible fading better in full sun. Richcliff is a fine modern option as long as you choose a lighter color and are willing to manage efflorescence from hard water. We can show you samples of both lines at your home.
Unilock paver work in Pasadena is priced by the project, and here are the ranges we typically see:

| Paver Patio Installation | $3,500 – $11,000 |
| Driveway Replacement | $5,000 – $14,000 |
Every project gets a written, line-item price before any work starts. The price you see on paper is the price you pay at the end – no footnotes. Call (626) 714-2992 for an exact quote.
