Most homeowners decide between paver brands by walking into the showroom and picking the color they like. Most installers decide between brands by which one comes back with a warranty problem. We've been laying Unilock since 2003 and laid two competitor brands during the 2008–2010 stretch when supply was tight. Here's what 23 years of installs have surfaced.
The four things that separate paver brands
Pavers all look pretty similar in a brochure. Up close, four specs matter — and the brands that get it right cost 10–20% more for reasons that show up in year 8.
Production tolerance
Unilock's spec sheet says ±1.5mm on dimensional tolerance. That means a "Brussels Block 6×6" paver is 6.000 inches wide give or take 1.5mm; a discount brand might run ±4mm. Tighter tolerances mean the joint width stays consistent across the patio — the eye reads it as a single field, not a checkered surface where some joints are tight and some are wide.
You don't notice this on the showroom display because the display has 8 perfect pieces. You notice it on a 600-square-foot patio where 200 pavers are 1mm tighter and 200 are 3mm looser. The discount brand looks unsettled; the premium brand reads like architecture.
Freeze-thaw rating
Every paver carries a freeze-thaw rating expressed in cycles before degradation. Unilock's rating runs 1,000+ cycles; competitor pavers run 200–600.
DuPage gets about 80–100 freeze-thaw cycles per winter. Math: a 200-cycle paver degrades in two winters; a 1,000-cycle paver outlasts the homeowner. Discount-brand patios installed in 2018 are starting to face-spall in 2026.
Color durability
Unilock pigments are integrated through the entire paver — the color you see is the color all the way through. Discount brands face-stamp the pigment; the bottom of the paver is gray concrete. When the surface wears, the discount paver shows the gray; the Unilock paver still shows the color.
We replaced one section of a 2014 discount-brand patio in Wheaton last year. The pigment had worn off the high-traffic areas; the homeowner could see the unfinished concrete underneath. Same patio in Unilock would have aged into the property; this one had to be reset.
The warranty
Unilock backs their pavers with a 25-year transferable warranty — meaning the warranty follows the property if you sell. The discount brands run 5–10 years and don't transfer. Buyers and inspectors pay attention to this; we've seen it surface in resale negotiations as a $4,000–$8,000 swing.
Where the premium actually shows up

Unilock-trained crew, no subcontracted base prep, and a 5-year installation warranty. Two decades of paver experience under one project lead.
See the service →The retail markup on Unilock vs. discount is about $0.80–$1.20/sq ft. On a 600-square-foot patio, that's $480–$720. The labor cost is the same. So a "Unilock" patio costs the homeowner $480–$720 more than a "discount" patio for the materials, full stop.
Where does that $720 go? Five places:
- Production tolerance keeps the install crew from cutting custom pieces ($240 of labor saved on a typical install).
- Freeze-thaw rating delays the first major repair by 8–10 years (saves $4,000–$6,000 in lifecycle cost).
- Color durability extends the "looks new" window by 4–5 years (immaterial in cash, material in resale appraisal).
- Transferable warranty adds documentation at resale (worth $4,000–$8,000 in negotiations per the homes we've sold).
- Unilock's installer-certification program makes the warranty enforceable. Discount brands often deny warranty claims unless the installer is "certified," which they sometimes don't enforce.
What we'd actually pick from the catalog
The Unilock catalog runs ~80 SKUs. Most homeowners don't know which to pick, so they pick by what's on display in the showroom. Here's what we'd specify on our own properties:
- Brussels Block (Sierra blend): the workhorse. 90% of the patios we install. $26–$28/sq ft. Tumbled edge, three-color blend that hides minor wear.
- Senza: the contemporary line. $30–$32/sq ft. Smoother face, narrower joint look. Right for modern home architecture.
- Estate Wall + caps: for the retaining walls that frame patios. Pairs visually with Brussels Block. $42–$60 per linear foot installed.
- Skip: Stonehenge entry-level — looks fine, but the freeze-thaw rating runs 600 cycles which is borderline for DuPage.
What we'd never specify
The discount brands. We've installed Cambridge and Pavestone on three jobs over the years where the homeowner's budget required it. Two of those jobs called us back inside 8 years for face-spalling; the third hasn't yet but we expect it.
The math is brutal: save $720 on the materials in 2026, spend $4,000–$6,000 in 2034 on a partial reset. Plus the homeowner-frustration cost of having a patio that looks tired at year 8.
When discount makes sense
Two cases. First, a temporary install — a homeowner planning to sell in 5 years and wants the patio for the listing. Second, a back-of-house path that will rarely be seen and never carry weight. Anywhere in the high-visibility, high-use zones of the property, premium pays back in lifecycle cost and resale value.
How we ship our quotes
Every Sunset Services hardscape bid lists the brand, the SKU, and the freeze-thaw rating in the spec line. If you're looking at three bids and two of them say "premium pavers" without naming the brand, you're being asked to imagine the same product across three quotes. They are not the same product.
