AfterUnilock Construction in Modesto, CA | Barrett & Sons Construction
We provide independent Unilock paver and retaining wall service across Modesto, from patio teardowns to driveway rebuilds, and we know exactly how valley clay treats these pavers after twenty years of wet winters and 105-degree summers. The short version: if your Unilock patio is sinking, separating, or sprouting weeds through every joint in 95355, 95356, or 95357, we’ve seen it before and we fix it so it stays fixed. Call (877) 610-1318 for a free estimate, and we’ll come look at your pavers in person.
Barrett & Sons Construction has been doing local building and hardscape work since 1998, and we’ve earned our reputation in Modesto by pulling permits, writing change orders before any price moves, and standing behind every job with our 90-Day Done Right Promise. We’re independent, not manufacturer-affiliated, which means we answer to you and the permit inspector, not to a brand rep. For deeper background on how we approach Unilock work, see our Unilock sales & service page.
Why Modesto Residents Choose Us for Unilock Service
Unilock pavers are well-made, but they’re only as good as the base under them, and Modesto‘s adobe clay is a base that fights back. We’ve rebuilt hundreds of failed walks and patios across this city, which means we know how Richcliff and Brussels Block behave when the soil beneath them heaves and shrinks through the cycle of winter fog and summer drought. That experience is the difference between a patch that sinks again in two seasons and a rebuild that holds for decades.
Tom Barrett started this company because his oldest boy showed the same interest in tools Tom had at sixteen, and that family investment still shows up on every job. We source genuine Unilock pavers and coping straight from regional dealers so colors and profiles match the original install, and we use high-density polymeric sand and stainless edge restraints rated for clay soils. No generic substitutes, no short cuts on base prep. We live here, and when we’re done with your patio, we’ll see you at the hardware store.
Common Unilock Construction Problems We Solve in Modesto
- Edge creep and joint blowouts on 2000s patios. Many original Unilock installs from the speculative boom years went in with no edge restraint or geotextile, and Modesto’s expanding clay pushes those edges outward every winter. Your paver border starts to bow, then the whole field loosens.
- Sunken pavement over trench lines. When utility crews backfill without proper compaction, individual Unilock pavers begin to teeter and chip. We see this constantly in east Modesto subdivisions where PGE and city water work cut through front walks and aprons.
- Efflorescence and surface spalling from sprinkler overspray. East-side tract homes with angled sprinklers keep Unilock pavers permanently saturated with high-mineral Modesto water. That white crust and flaking surface isn’t a paver defect; it’s a watering problem we solve by adjusting coverage and re-sealing.
- Bulging retaining walls at mid-height. On 95355 hillside lots, clay swell pushes against the backside of Unilock walls that were originally installed without drainage stone. The wall bows, the coping separates, and water has nowhere to go.
- Weed-choked, sand-starved patios on foreclosed homes. Modesto’s 2008 foreclosure crisis left thousands of homes vacant for years, and their Unilock patios in 95355-95357 filled with weeds, lost their joint sand, and shifted enough to fail city resale inspections. We tear them up and rebuild them properly.
Unilock Service in Modesto: What Local Conditions Mean for Your Equipment
Modesto is one of the few Central Valley cities where foreclosed homes sat vacant long enough that their Unilock patios in 95355 through 95357 became weed-choked, sand-starved, and shifted enough to fail city resale inspections, which means we get called in to tear up and reinstall pavers that look fine until you pull up the first course. That’s the hidden cost of the 2008-2010 housing collapse here: a decade and a half later, local owners still inherit hardscape that was never maintained and never built for valley soil in the first place.
Then there’s the clay itself. Modesto sits on San Joaquin Valley adobe-clay soils that swell in wet winters and shrink during drought summers, and the movement is dramatic enough to separate a Unilock field from its edge restraint within a few seasons. A slab or paver base that looked fine at the 2005 final inspection has often moved an inch or more by now, especially on the east side where homes went up fast during the boom. Contractors who don’t understand Central Valley soil underestimate that movement every time, and the homeowner pays for it twice.
Unilock Models & Products We Service in Modesto
We service the full range of Unilock product lines across Modesto, including Richcliff, U-Cara, Hollandstone, and Brussels Block. When a section of your 2000s driveway or walk needs replacement, we match the existing paver color and profile through regional dealers so the patch doesn’t read as a patch. When the underlying base failure is extensive, we recommend a full reinstallation with proper geotextile and edge restraints over a patch that will sink again within two seasons.
Our crews stock the high-demand accessories locally for fast Modesto turnaround: high-density polymeric sand for clay soils, stainless edge restraints made for expansive conditions, and geotextile separators. We don’t use cheap generic substitutes because we’ve watched them fail here year after year. Your Unilock pavers deserve a base that respects the soil they sit on.
Unilock Service Pricing in Modesto
Here are the ranges we quote most often for Unilock and related hardscape work in Modesto. These are line-item prices, not vague “starting at” numbers:
| Service | Modesto Price Range |
|---|---|
| Paver Patio Installation | $3,500 – $11,000 |
| Paver Driveway Installation | $7,000 – $18,000 |
| Concrete Driveway Installation | $4,500 – $12,000 |
What actually drives the cost is what’s under the pavers. If the base was never compacted properly, or there’s no geotextile over clay, or the edge restraints are missing, the price moves up because we’re rebuilding a foundation, not just re-setting pavers. We’ll give you a written scope, written allowances, and a written change order before any price moves. Call (877) 610-1318 for a free estimate, and we’ll tell you exactly what you’re dealing with.

FAQs – Unilock Construction in Modesto
Street-edge sinking is almost always a utility trench backfill problem. When the city or PGE cuts across your apron and backfills without proper compaction, the soil settles over a couple of years and your Unilock pavers drop right along the trench line. The fix is to pull the pavers, re-compact the trench in lifts, and reinstall with edge restraints. Call (877) 610-1318 and we’ll assess the trench line for free.
It’s normal for Modesto clay, but it’s not what Unilock intended. The clay under your patio has been swelling and shrinking seasonally, and without a geotextile separator and proper edge restraint, the pavers shift and the joint sand washes out. Weeds sprout in every gap. We rebuild these patios with the proper base and restraints so the movement stops and the weeds have nowhere to grow.
Yes. We source genuine Unilock pavers direct from regional dealers and match color and profile to the existing field. Fair warning: two decades of Central Valley sun and sprinkler minerals have faded the original surface, so the match will be slightly fresher. We blend the new pavers into the old field so the transition reads as natural. Call (877) 610-1318 for a color match assessment.
We trench behind the wall, install a perforated drain wrapped in geotextile, and backfill with clear drainage stone so water never builds up against the backside. Modesto clay holds water like a sponge, and without drainage, the wall bulges. The original installs that skipped this step are the ones we rebuild every winter.
For a ground-level paver patio, typically no permit is required, but if your project involves a retaining wall over three feet or changes to site drainage, the city may require one. We pull permits on every eligible job and sign every inspection, because the permit inspector works for you, not for me. Call (877) 610-1318 and we’ll check your specific project against current Modesto code.
We’ll do it right the first time, or we’ll come back and make it right.
