Tremron Home Additions & ADU: The Fort Myers Owner’s Guide
If you’re reading this, you’ve probably got a Tremron paver or wall block product on your property and something isn’t right. Maybe the soldier course on your patio is pulling away, a retaining wall is leaning after the last tropical storm, or the base under your driveway pavers has settled into a low spot that holds water. When you’re adding square footage to your home or building an ADU in Fort Myers, the hardscape around it matters just as much as the structure itself. We stock and install Tremron-compatible pavers, wall blocks, and coping for home additions and ADU projects, with most full installations running between $45,000 and $130,000 depending on scope, drainage requirements, and lot conditions here in Lee County.
We’re an independent contractor, not part of Tremron, which means we can be straight with you about what works and what doesn’t in Southwest Florida’s climate without a sales script getting in the way.
Which Tremron Products We Work With for Additions & ADUs
Tremron manufactures pavers, wall blocks, fire pits, and outdoor kitchen components at their Florida plants, and we’ve installed their full lineup across Fort Myers, from McGregor Boulevard estates to new construction out in Gateway. The product families most relevant to a home addition or ADU project are the paver lines used for driveways, pool decks, and patios, plus the wall systems that handle grade changes and planter boxes.
The key compatibility issue most owners miss involves the specific series: Tremron’s Olde Towne Cobble, Sierra, and Holland Stone lines each have slightly different joint widths and thickness tolerances. If your existing patio was built with Olde Towne Cobble in the Rio color blend and you’re adding an ADU that needs a connecting walkway, trying to match it with a different series creates a visible seam that can’t be hidden by polymeric sand alone. We match by taking a physical sample from your existing installation, pulling the mold number off the back of the paver, and confirming batch availability through Tremron’s Fort Myers distribution yard off Alico Road. That extra step prevents the mismatch you’ll see on half the home addition projects in town where another contractor just grabbed whatever was in stock.
Signs Your Tremron Hardscape Is Failing Around Your Addition
- Pavers sinking or separating near the foundation connection. This almost always traces back to inadequate base compaction where the new addition meets the existing hardscape. In Fort Myers, our sandy soil compacts differently than the clay soils up north. Without a proper geotextile fabric and at least 6 inches of compacted limerock base, you’ll see settlement within the first rainy season.
- Retaining wall blocks tilting forward after heavy rain. Tremron wall blocks are designed with a lip system that locks each course together, but that system depends on a level base and proper drainage behind the wall. When you see leaning, the weep holes are likely clogged or the drain field gravel behind the wall was skipped entirely. We see this on half the retaining walls we inspect in Fort Myers neighborhoods like Whiskey Creek and Fort Myers Shores.
- Efflorescence that won’t scrub off. A white, chalky film on your Tremron pavers signals trapped moisture wicking through the concrete. It’s cosmetic, but persistent efflorescence on a wall that’s only two years old usually means the cap isn’t sealed correctly or the grading directs water toward the wall instead of away from it.
- Gaps opening between the coping and pool deck. Pool coping takes the most abuse from our Florida sun and pool chemicals. Tremron bullnose coping stones can shift when the mortar bed underneath cracks from thermal expansion. If you’ve got a gap wider than a quarter-inch, water is getting behind it and accelerating the damage.
- Pavers fading unevenly across the addition footprint. Tremron color blends are consistent lot-to-lot within a production run, but if your original patio was installed in 2018 and you’re adding a new section now, even the same color name will look different. UV exposure and foot traffic have aged your originals. We lay out a blending plan that feathers old and new pavers together so the transition disappears rather than looking like a patch job.
Replacement & Installation Cost in Fort Myers
A Tremron-based hardscape package for a home addition or ADU in Fort Myers typically falls between $45,000 and $130,000 installed. The spread isn’t arbitrary. It comes down to three things: how much square footage you’re covering, what the subgrade looks like once we excavate, and how much drainage infrastructure the site needs to meet Lee County code.
Here’s how that breaks down on a typical project:
- Excavation, base prep, and compaction: $8-$15 per square foot. Sandy Fort Myers soil usually means bringing in limerock and compacting in lifts. Skip this step and you’ll be back here in three years with the same problem.
- Tremron paver installation (driveway, patio, walkway): $12-$22 per square foot, including the polymeric sand and edge restraint. The higher end reflects complex patterns like herringbone or jobs that require extensive cutting around curved foundation walls.
- Tremron retaining wall or seat wall: $45-$75 per linear foot for walls under three feet. Taller walls that need engineering and geogrid reinforcement run $80-$150 per linear foot.
- Drainage (catch basins, French drains, downspout tie-ins): $2,000-$8,000 depending on how much water we’re managing. A lot with poor percolation or a high water table out near the Caloosahatchee can push this to the upper end.
Every estimate from us is a written, line-item quote. The number you see is the number you pay. That’s been our policy since Derek Hollenbeck started this company, and our 730-Day Done Right Promise backs every paver we set - if something settles or shifts within two years of completion, we come back and make it right at no charge.
DIY or Call Us?
You can clean and re-sand your Tremron pavers yourself. If the joints between pavers have washed out and you’re just refreshing polymeric sand on a flat patio, that’s a reasonable Saturday project. What you shouldn’t attempt is resetting pavers that have sunk near a foundation, rebuilding a retaining wall taller than two feet, or regrading around an ADU to fix drainage. Those aren’t cosmetic fixes. They involve compaction equipment that weighs hundreds of pounds, an understanding of how water moves through Florida’s sandy soil profile, and a real risk of making the drainage problem worse by trapping water against your foundation.
Retaining walls over three feet in Fort Myers also require a permit and an engineered design. We handle that start to finish, from the soil report to the final inspection. If you’re staring at a leaning wall or pavers that have pulled away from your new addition, call (844) 638-7249. We’ll come look at it and give you an honest assessment and a written estimate.
FAQs
A properly installed Tremron paver system in Southwest Florida lasts 25 to 40 years before the surface shows enough wear to consider replacement. The pavers themselves are compressed concrete rated at 8,000+ PSI, so they don’t crack from vehicle loads. What shortens their lifespan here is UV degradation of the color and settlement from our seasonal rain cycles saturating a poorly compacted base. We’ve pulled up 30-year-old Tremron patios in Fort Myers that looked nearly new underneath because the original contractor did the base right.
Yes, and we do it often. If the damage is confined to a low spot, a cracked area, or pavers stained by a grill grease spill, we can lift and reset just that section. The challenge is color matching. Your existing pavers have years of sun and weather on them compared to a brand-new pallet. We address this by pulling pavers from a less visible area of your property to fill the repair zone and putting the new ones where they’re less noticeable. Call (844) 638-7249 for an exact quote - estimates are free.
For a typical ADU with a driveway extension, walkway, and small patio, plan on 5 to 10 working days from excavation to final sanding. The timeline stretches if we’re building retaining walls, running new drainage lines, or if the project falls during our summer rainy season when afternoon thunderstorms stop work for the day. We give you a schedule upfront and stick to it. Our crews show up in uniform, background-checked, and we don’t disappear mid-job to start someone else’s project.
We don’t warehouse large quantities of Tremron product at our yard because color blends and series selection vary so much from project to project. What we do is pull directly from Tremron’s Fort Myers distribution yard, usually with next-day availability for their core lines like Olde Towne Cobble, Holland Stone, and Sierra. For less common products or special-order colors, it’s a 3- to 7-day turnaround. We include the paver cost, delivery, and any material lead time in your estimate so there are no surprises.
