Unilock Construction in Westminster, CA | Alder Contractors
We provide independent Unilock paver installation and repair across Westminster and nearby, including Unilock service in Huntington Beach, from Brussels Block driveways on postwar ranch lots to Town Hall entry bands on Bolsa Avenue storefronts. What makes our Unilock work different here is that we plan every base, slope, and edge restraint around Westminster’s shared driveway approaches and compact lot drainage, because that’s what actually determines whether a paver field in this city stays flat. We’re not manufacturer-authorized or warranty-endorsed by Unilock, and we tell every client that up front. Call (833) 467-7020 for a free estimate on your paver driveway, patio, or commercial frontage.
Why Westminster Residents Choose Us for Unilock Service
Nelson Ibarra grew up in the Willow Avenue corridor of Rialto and spent three decades on Inland Empire job sites before building Alder Contractors, so when we set a paver base, we’re thinking about what that ground will do after three wet winters, not just how the finished field looks on install day. We’re a licensed general contractor with material access to 50+ established brands, including Unilock, Belgard, and Techo-Bloc hardscape lines, which means we can source genuine Unilock units, edge restraints, and polymeric joint sand without a middleman delay — the same supply chain that supports our Stanton Unilock service. For Westminster homeowners, that translates to a single crew handling excavation, base work, paver setting, and drainage under one contract. We don’t sub out the critical layers. Do it right the first time; the callback always costs more than the extra hour up front.

Common Unilock Construction Problems We Solve in Westminster
- Base failure under Brussels Block driveways: Most 1950s to 1970s ranch homes in Westminster had patios and walkways laid on thin sand over original graded soil. After a wet winter, the pavers look fine but the field ruts and heaves. We over-excavate, compact a proper aggregate base, and re-set the same pavers when they’re still dimensionally sound.
- Creeping paver courses along shared driveway lines: Compact lots and duplexes in 92683 and 92684 frequently share an approach apron with a neighbor. Old installs used minimal or wood edge restraint, so courses open up along the property line. We set stiffer restraints and re-align the field so the shared edge stays put.
- Joint sand washout after turf removal: Westminster’s drought-conscious landscaping push means homeowners pull lawn and re-grade, which redirects runoff across paver fields. Beacon Hill patios and Town Hall walkways end up with scoured joints and stained faces. We re-sand with polymeric joint sand and correct the slope so water moves off the field instead of through it.
- Spalled edges on Bolsa Avenue commercial aprons: Landlord-grade paver entry bands along Little Saigon storefronts take delivery-truck and grease-trap service traffic. Low-base installs show settled edges and chipped corners within a few years. We rebuild those sections with proper base depth and stronger edge treatment.
- Failed paver driveways being patched with mismatched units: A lot of Westminster driveways have been spot-patched over the years with whatever paver was on sale. Color and dimensional mismatch gets worse every repair. We lift and re-set with genuine matching series so the field reads as one surface again.
Unilock Service in Westminster: What Local Conditions Mean for Your Equipment
Westminster’s residential fabric is dominated by 1950s to 1970s single-story ranch and tract homes on compact lots, plus dense pockets of duplexes and fourplexes on the same blocks. That means paver driveways here frequently share a single approach apron and drainage path with a neighboring driveway, a condition you rarely see on newer Orange County tract streets with wider setbacks. Our base, slope, and edge-restraint detail has to shed water to the street without pushing it onto the adjacent parcel. On a compact ranch lot off Bolsa Avenue near the Little Saigon commercial spine, a homeowner wanted their failing concrete driveway replaced with Brussels Block. The shared approach with the neighboring duplex meant our slope and drainage had to shed to the street without dumping runoff on the adjacent lot. We cut out the old slab, over-excavated and compacted a deeper aggregate base, set a stiffer edge restraint along the shared line, and hand-troweled the joint sand so the field drained cleanly and the neighbor’s apron stayed dry through the next rain. That’s the daily reality of hardscape work in Westminster, and it’s why generic paver installation specs written for newer subdivisions don’t hold up here.
Unilock Models & Products We Service in Westminster
We install and repair the full Unilock residential and commercial line, but the ones we see most in Westminster are Brussels Block, Beacon Hill, Town Hall, and the Seneca retaining wall system. Brussels Block is the workhorse for driveway and patio work in older Orange County tracts, thanks to its tumbled, dimensional profile that hides minor wear. Beacon Hill smooth-faced pavers show up on patio and walkway fields where a cleaner face matters. Town Hall modular units work well for walkways and accent bands. For grade changes on compact lots, Seneca retaining wall units handle the transition without eating usable yard space. We buy genuine Unilock units, edge restraints, and polymeric joint sand rather than mixing in generic pavers, because color and dimensional match across phased repairs depends on the actual series. For phased work in Westminster, we keep a rotating stock of common Brussels Block and Town Hall units locally so we can pull matching material quickly.

What drives the cost on a Westminster Unilock job is base depth, drainage correction, and whether we’re working on a shared lot line that needs extra restraint and grading. A paver patio on flat, stable ground runs lower. A shared driveway approach that needs over-excavation and a new drainage path runs higher. Every free estimate from us includes a written line-item quote with the base, restraint, pavers, and joint sand broken out separately, so you see exactly where the money goes.

FAQs – Unilock Construction in Westminster
Can we install Unilock pavers over our existing Westminster driveway concrete to save money?
No, not if you want the field to last. Westminster’s older ranch lots were graded in the 1960s and 70s, and the concrete underneath has usually shifted or cracked along the same lines the new pavers would follow. We remove the slab, compact a proper base, and set the pavers so they drain and hold. The savings from skipping that step disappear within two to three winters. Call (833) 467-7020 and we’ll give you an honest read on what your slab can and can’t carry.
Our duplex shares a driveway approach with the neighbor – how do you handle the property line?
We treat the shared line as a drainage boundary, not a visual afterthought. That means a stiffer edge restraint along the property line, slope set to shed water to the street, and joint sand compacted so nothing migrates toward the neighbor’s parcel. We’ve done this on compact lots across 92683 and 92684, and we check the grade with a level before we ever set the first paver.
Which Unilock line holds up best against a Santa Ana wind and dry-summer sun on an exposed patio?
Brussels Block, hands down. The tumbled face and dimensional profile hide the small surface wear that Santa Ana wind and dry heat cause over time, and the color range doesn’t show sun fade the way smoother-faced lines can. Beacon Hill looks great on shaded patios, but for a fully exposed Westminster backyard, Brussels Block reads better for longer.
Can you install a paver apron or entry band for a shop along Bolsa Avenue?
Yes, and we’ve done them. Commercial frontage along Bolsa takes delivery-truck turns and grease-trap service traffic, so we build those aprons to a deeper base spec than residential work and set the edges to hold. Westminster plan-check and sign-permit timelines can move a job, but our scope is the hardscape, not the tenant improvement paperwork. Call (833) 467-7020 to talk about your storefront.
How do we match new pavers to an existing Unilock field already on the property?
We buy genuine Unilock units from the same series, not a generic lookalike. Brussels Block, Beacon Hill, and Town Hall each have specific dimensional and color tolerances that only the actual series matches. If the existing field is too sun-faded or worn, we’ll tell you honestly that a clean match isn’t possible and we’ll rebuild the section instead of leaving you with a patch that shows. Estimates are free, so call (833) 467-7020 and we’ll take a look.
