Tremron Home Additions & ADU: The Huntington Beach Owner’s Guide
We stock and install Tremron-compatible hardscape components for home additions and ADU projects in Huntington Beach, with typical installed pricing for integrated paver patios, walkways, and retaining walls running $7,000-$18,000 for paver driveway-adjacent work and $45,000-$130,000 for full home additions that incorporate Tremron surfaces. Most Tremron paver replacement and repair calls in Huntington Beach are scheduled within 24-48 hours, with common Autumn Gold, Sierra, and Olde Towne series units in stock. Homeowners usually discover a failing Tremron installation when pavers shift or settle after winter rains, when joint sand washes out near the Bolsa Chica marsh’s high water table, or when a previously level patio develops pooling that wasn’t there in the dry season.
Which Tremron Models This Applies To
Tremron manufactures several paver series that appear regularly in Huntington Beach home additions and ADU hardscaping, and identifying your exact series determines whether we match OEM or move to an equivalent that performs better in coastal Orange County’s salt-air environment.
The Autumn Gold and Sierra lines are the most common in local ADU courtyard installations from 2015-2022, typically 60mm thickness in 6×6 and 6×9 configurations. The Olde Towne series, often used for permeable driveway extensions tied to garage conversions, runs 80mm and carries a different edge profile that won’t interlock correctly with 60mm replacements. Check the spacer bars on the paver underside or the stamped Tremron code on the edge of any remaining original unit.
We source direct from Tremron’s Florida manufacturing for color-matched replacements when the lot code is legible. When it isn’t, we stock Belgard and Techo-Bloc equivalents with comparable compressive strength (8,000+ PSI) that integrate cleanly and carry the same written warranty. Rowan Construction Group Huntington Beach is an independent contractor and is not affiliated with Tremron.
Signs Your Tremron Home Additions & ADU Is Failing

- Pavers rock underfoot or sink in clusters. This usually indicates inadequate base compaction during the original install, common in Huntington Beach’s sandy loam near the coast where crews sometimes shortcut the 4-inch minimum compacted aggregate base. The void beneath allows water to accelerate settlement during our brief but intense winter storms.
- Joint sand washes out repeatedly after rain. Polymeric sand failure happens faster within two miles of the Pacific due to salt crystallization breaking the bond. We see this most often on Tremron installations that used standard joint sand instead of the stabilized product specified for coastal zones.
- Efflorescence blooms that don’t clean off. White mineral deposits indicate moisture migration through the paver body, often from improper drainage slope or a failed vapor barrier beneath the bedding layer. In ADU patios with roof runoff directed onto the surface, this accelerates dramatically.
- Chipping or spalling on driveway-adjacent Tremron surfaces. The 60mm residential pavers weren’t designed for vehicle loading; garage conversions that retained the original paver apron see this failure pattern by year five or six in our market.
- Weeds growing through joints despite sealing. This signals a breakdown in the bedding layer or base, not a surface problem. The root structure follows the moisture channel, and in Huntington Beach’s mild climate, weed growth is nearly year-round.

AfterReplacement Cost & What’s Included
| Scope | Price Range in Huntington Beach |
|---|---|
| Tremron paver patio repair / partial reset (up to 200 sq ft) | $3,500-$8,500 |
| Full Tremron paver replacement with corrected base (up to 400 sq ft) | $7,000-$18,000 |
| Home addition with integrated Tremron hardscape | $45,000-$130,000 |
| ADU with courtyard / walkway Tremron installation | $90,000-$220,000 |
The range depends on three factors: whether we can salvage and relay existing pavers (saves 30-40% on material), how much base reconstruction is needed, and whether the project ties into permitted ADU work requiring inspection. Every quote is a flat written price with line-item scope before work starts, under Clause 1 of the Haven Standard. Our 365-Day Done Right Promise covers the installation, and the documented photo record shows you the base condition before we cover it.
DIY or Call Us?

There’s an honest line here. A homeowner can safely check whether pavers are loose by hand, verify the Tremron stamp on an edge piece, and photograph the failure pattern for a quote. What doesn’t work as DIY: lifting settled sections without proper base reconstruction, which guarantees the same failure in 18 months, and any cutting with a wet saw near the house without dust containment.
The real risk is structural. Pavers that have settled indicate compromised base material, and simply relaying them traps the underlying problem. We’ve pulled up “fixed” DIY jobs in the Huntington Beach Highlands where the homeowner added an inch of sand that washed out in the first season. Measure twice, price once, and put it in writing. Call (657) 288-3368 and we’ll scope it properly.
FAQs
Properly installed Tremron pavers last 25-30 years in inland Orange County, but within a mile of the coast, salt air and moisture cycling reduce that to 18-25 years unless stabilized joint sand and sealed surfaces are maintained from year three. Call (657) 288-3368 for an exact quote on your specific installation - estimates are free.
Individual units can be lifted and relayed if the base is intact, but settlement over 3/8 inch indicates base failure that relaying won’t fix; we quote both options when we inspect. Call (657) 288-3368 for an exact quote - estimates are free.
A 200-square-foot patio reset with base correction takes 2-3 days, including compaction and joint sand curing time; full ADU-integrated hardscape runs 1-2 weeks depending on inspection scheduling with the City of Huntington Beach. Call (657) 288-3368 for an exact quote - estimates are free.
We stock Autumn Gold, Sierra, and Olde Towne in the most common Huntington Beach color blends, with specialty orders arriving in 7-10 business days from Tremron’s Jacksonville plant; equivalent Belgard and Techo-Bloc lines are typically next-day from our Orange County supplier.

We’ll inspect the installation, photograph the base condition, and deliver a flat written price with scope before any work starts - that’s Clause 1 of the Haven Standard, and it’s how we’ve kept 4,000-plus projects within a few percent of the agreed cost since 2007.
