Tremron Home Additions & ADU Nationwide

Tremron Home Additions & ADU: The Miami Owner’s Guide

Tremron pavers, retaining wall blocks, and patio stones are built for Florida, but the structures around them often aren’t. In Miami, we handle home additions and ADU construction where Tremron products are the foundation, and the installed cost typically runs $53,100 – $153,400. You usually discover the problem not in the pavers themselves, but in the addition sitting on them: a door that suddenly sticks, a floor that slopes toward the new wing, or a hairline crack running up through the stucco from the paver base. That’s the structure telling you the ground under the Tremron material shifted, and it’s time to address the addition before the issue moves into the living space. We stock Tremron-compatible base material, edge restraints, and replacement pavers on the truck for exactly these call-outs, and we can usually get eyes on the problem the same week you call (850) 988-7559.

Which Tremron Models This Applies To

If your Miami addition or ADU sits on Tremron pavers, block, or wall units, the compatibility question usually starts with the product line. Tremron’s Travertine Series uses a 60mm paver in 6×12, 12×12, and 16×16 formats that need a compacted base of at least 4 inches of crushed concrete, then 1 inch of bedding sand. Their Riviera Series comes in 40mm thickness and is better suited to foot-traffic patios than driveway-rated loads. A common gotcha in Miami: homeowners pour a slab for the addition, then butt Tremron pavers against it without a proper edge restraint, and the pavers start drifting within two seasons of freeze-and-thaw cycles near the slab line. We always verify the specific product with the label stamp on the underside of the paver or a leftover box from the original install. Penhallow Remodeling Miami is an independent provider, not a Tremron dealer, but we work with their product lines consistently because they’re the standard in South Florida. We also handle components from KraftMaid, Cambria, and Silestone when an addition or ADU includes kitchen or bath finishes.

Signs Your Tremron Home Additions & ADU Is Failing

• Pavers sinking near the addition’s foundation. This is usually base failure: Miami’s sandy soil shifts after heavy rains, and if the original base wasn’t compacted in lifts, the pavers sink. You’ll see a low spot where water pools next to the new structure.
• Edge pavers separating from the slab or house wall. The edge restraint was either never installed or failed. Once edge pavers move, the whole field can start drifting, and you’ll feel a loose paver underfoot.
• Cracks running through the stucco or drywall of the addition. If the ADU is on a slab and the Tremron pavers outside are shifting, the crack pattern usually starts at the corner of the new structure and travels upward. This tells you the soil movement is affecting the addition, not just the patio.
• Doors or windows in the addition binding. When a door that used to swing freely starts sticking at the top corner, the header or the floor plane has moved. It’s rarely the door. It’s the structure, and it’s often tied to what’s happening under the Tremron surface outside.
• Water pooling against the addition’s foundation after a storm. Miami’s rain is relentless, and if the pavers pitched away from the house originally but have settled, you now have water running toward the new wing. That’s a slow rot problem in the making.

Replacement Cost & What’s Included

A full home addition with Tremron-compatible exterior work in Miami runs $53,100 – $153,400. A smaller ADU, if you’re scoping the entire structure, can push toward $106,200 – $259,600 depending on finishes, square footage, and site prep. The range for this page covers the structural repair plus the Tremron surface work: base excavation and re-compaction, new edge restraints, replacement pavers or blocks as needed, and re-pitching away from the structure. What drives the number up is access (tight Miami lots behind gates cost more), the depth of base failure, and whether we’re matching existing Tremron product that’s no longer in production. Our written quote spells out parts and labor separately, so you see exactly what the material costs versus what the crew costs. And every job is covered by the 365-Day Done Right Promise: if the pavers shift again inside a year, we return and fix it at no charge. Penhallow Remodeling Miami operates under The Kingswell Way, which means a written price before any work starts, a defined arrival window, and a written guarantee on every project. We install under the same standard whether we’re repairing a kitchen in Coconut Grove or rebuilding a paver base in Kendall.

DIY or Call Us?

You can safely check a few things yourself. Pick up a border paver near the addition and look at the base underneath: if you see sand that’s washed out or no compacted aggregate at all, that’s useful to note. Check if the pavers pitch toward or away from the structure with a 4-foot level. What you shouldn’t do is start pulling up a paver field that’s butted against the addition’s foundation, because you can destabilize the edge that’s holding the remaining pavers, and then the problem spreads. You also shouldn’t try to re-compact a base with a rental plate compactor if you don’t know whether the original failure was from poor compaction or a drainage issue; doing the wrong fix means paying twice. If the door is sticking or you have cracks in the new addition, that’s structural, and you need a general contractor on site, not a paver patch. Give you a number first, then pick up the tools. Call (850) 988-7559 and we’ll schedule a walkthrough and hand you the written estimate before any tools come off the truck.
