Tremron Home Additions & ADU: The Woodland Hills Owner’s Guide
We stock and install Tremron-compatible hardscape and masonry components for home additions and ADU projects across Woodland Hills, with full addition work typically running $45,000 to $130,000 installed. Most Woodland Hills homeowners discover a Tremron part has failed when a retaining wall shifts, a paver settles near a new foundation line, or a bond beam cracks along an addition’s stem wall. You’ll know it when you see it: a paver that sits proud of its neighbors, a capstone that rocks under foot, or a hairline crack that lets water track into the ADU’s slab edge.
Which Tremron Models This Applies To
Tremron manufactures concrete pavers, retaining wall block, and segmental wall systems under several product lines that show up constantly in Woodland Hills addition and ADU work. The three we handle most are the Mega Olde Towne paver line, the Legacy retaining wall system, and Tremron’s bullnose coping units that cap pool-adjacent planter walls. The parts that fail are rarely the pavers themselves. It’s the edge restraint, the base material, or a retaining wall block that took water intrusion and spalled. Here’s what you need to know about matching parts:
Tremron stamps a lot number on the underside of most pavers and on the top lip of wall block. That number tells you the production run, which matters because concrete color shifts slightly between runs. If you replace one section of a Woodland Hills ADU patio with a mismatched run, you’ll see it. We match by lot number first, then by visual sample against your existing surface. Aftermarket equivalents from Pacific Interlock or Basalite can work if the dimensions and compressive strength match, but we default to OEM Tremron for anything load-bearing. It costs maybe 8 to 12 percent more and removes the guesswork on freeze-thaw and UV performance.

Signs Your Tremron Home Additions & ADU Is Failing
- Pavers rocking or shifting near the addition’s foundation line. This almost always means the base layer has eroded from water running off the new roofline. The paver isn’t the failure; the drainage is. Fix the water path first, then reset the pavers.
- Retaining wall block tilting forward at the top. The geogrid or deadman anchor behind the wall wasn’t installed deep enough, or water pressure is building up behind the wall. In Woodland Hills we see this most on hillside ADU sites where grading was cut tight.
- Cracks running vertically through consecutive wall blocks. That’s settlement below the wall’s footing, not a block defect. Adding fill without compaction is the usual culprit. The repair starts below grade, not on the face of the wall.
- Capstones loose or separated from the wall. Adhesive failure from UV exposure and heat cycling. Woodland Hills summers bake the adhesive; it turns brittle inside three to five years on south-facing walls.
- White chalky residue spreading across paver surfaces. Efflorescence, not structural failure, but it signals water moving through the paver body. On new ADU hardscapes it usually corrects itself, but persistent cases mean a drainage or vapor barrier issue beneath.

AfterReplacement Cost & What’s Included
Full home addition work in Woodland Hills runs $45,000 to $130,000, and ADU construction ranges $90,000 to $220,000. When the project scope is specifically Tremron hardscape repair or replacement tied to that addition, most homeowners pay between $3,500 and $11,000 for paver patio work, and $7,000 to $18,000 if a paver driveway is part of the addition’s footprint. What drives the price: how much of the base layer needs re-compaction, whether we’re removing and resetting existing block or installing new, and access to the work area. A hillside ADU in the streets above Topanga Canyon Boulevard costs more than flat ground near Warner Center because we’re hauling material by wheelbarrow, not by machine.
Every quote is a written line-item price before any work starts. You see the cost of the Tremron block or pavers, the base material, the labor, and the haul-away. No change orders unless we find something genuinely hidden, and we tell you before we touch it. The work carries our 365-Day Done Right Promise: if a paver settles or a block shifts within a year of completion, we come back and make it right, in writing, no argument.
DIY or Call Us?
You can reset a single loose paver. Pull it, check the base, add a little crushed stone, tap it back. That’s a Saturday job. What you should not do is rebuild a retaining wall that holds back soil against your ADU’s foundation, or re-level a paver section where water is pooling against the addition. Get the footer depth or drainage wrong and you’ve turned a $3,500 repair into a $45,000 foundation problem. The work tells you everything. We just make sure it tells the right story. If you’re in Woodland Hills and the wall or hardscape is tied to a structure you’re living in, have someone who does this every day look at it. Call (341) 217-2776 and Luca will come out, walk the site, and give you a straight answer on what it needs and what it costs.
FAQs
Twenty to thirty years for properly installed pavers, and thirty-plus for retaining wall block, even with our UV exposure and the occasional freeze cycle we get in the canyons. What shortens that lifespan is base failure and water, not the Tremron product itself. Call (341) 217-2776 if you’re seeing movement before year ten; something underneath is wrong.
Yes, if the failure is confined to a small area and the base is still sound. We can cut out and replace individual pavers or reset a short section of wall block. If settlement has spread or the drainage is wrong, a patch will fail again within a year or two. We’ll tell you which situation you have before you spend a dollar.
Small paver resets and capstone rebonding are usually done in a day. A retaining wall section rebuild takes two to four days, depending on height and access. Full paver patio reset around an ADU runs three to five days, including base re-compaction.
We stock common Tremron capstones, edge restraints, joint sand, and a rotating inventory of wall block from current production runs. For exact lot-matched pavers or special order colors, we source directly through Tremron’s distributor network, usually within three to five business days here in Woodland Hills. Estimates are free; call (341) 217-2776 for an exact quote.
