Tremron Home Additions & ADU: The Tampa Owner’s Guide
Tremron home additions and ADU construction in Tampa typically falls between $45,000 and $130,000 for a full addition, with detached ADUs running $90,000 to $220,000 depending on size, utility runs, and finish level. When a Tremron product fails or underperforms – whether it’s a paver base shifting, a retaining wall block cracking, or a drainage channel separating – the repair usually points back to the substrate, not the product itself. We stock the Tremron-compatible materials and install the structural fixes Tampa’s sandy soil and summer downpours actually demand.
Most Tampa owners discover the problem the way you did: a corner of the patio settles after a heavy rain, a section of retaining wall starts leaning into the yard, or a driveway paver cracks under a delivery truck. The Tremron product is rarely the culprit. It’s what’s underneath it. We’ll get into that below, but first: this page covers exactly which Tremron applications we work with, what failure looks like, what a fix costs, and whether you should touch it yourself.
Key Takeaways
- Installed home addition and ADU work in Tampa runs $45,000 to $130,000 for additions and $90,000 to $220,000 for ADUs, with a written price before any work starts.
- Most Tremron failures in Tampa are substrate or drainage problems, not product defects.
- We are an independent Tampa remodeling contractor, not affiliated with Tremron, but we install and repair Tremron-compatible hardscape and structural work every month.
- The 365-Day Done Right Promise applies to every Tremron-related repair and addition we complete.
Which Tremron Models This Applies To
Tremron manufactures concrete pavers, retaining wall blocks, and hardscape products across several Tampa-area product lines, including their Highlands, Olde Towne, and Mega series. The compatibility question matters less about the specific Tremron paver name and more about what’s happening underneath it. When we do a Tremron-related repair or addition in Tampa, we’re looking at the base course depth, the bedding sand, the edge restraint, and the drainage path. Miss any one of those and the new pavers fail the same way the old ones did.
For retaining walls, Tremron’s block sizes vary by series – some use a lip system, some use pins, some are gravity-stack. That changes what we can safely repair versus what needs a rebuild. The quickest way to identify your Tremron product is the stamp or texture pattern on the face, but if you’re not sure, send us a photo. Graham Stein has been matching Tampa hardscape failures to their causes for years, and he would rather look at a picture than guess.
On the OEM-versus-aftermarket question: for Tremron pavers and blocks, there is no functional aftermarket equivalent worth buying. The product is the product. What matters is the base, the compaction, and the joint stabilization. That’s where we put the money, and that’s where the difference between a repair that lasts three years and one that lasts twenty actually lives.

Signs Your Tremron Home Additions & ADU Is Failing
- Settling or dipping pavers near downspouts or roof edges. This is the classic Tampa failure. Rainwater concentrates at the edge of a home addition or ADU, saturates the base, and the pavers sink. The Tremron paver is fine; the drainage path isn’t.
- Retaining wall leaning or bulging mid-span. Tampa’s sandy soil holds water differently than clay. A wall that wasn’t backfilled with proper drainage stone will start to lean within three to five years. If you can see the wall moving outward at all, stop putting it off.
- Cracked or spalled pavers under routine foot traffic or vehicles. A paver that cracks under normal use is sitting on an uneven or too-thin base. The load isn’t spreading. Adding another paver on top doesn’t fix the base.
- Weeds or ants pushing up through the joints every few weeks. This means the polymeric sand has failed or was never installed correctly. In Florida’s wet season, a failed joint lets water and roots work their way under the whole surface.
- Water pooling on the paver surface after light rain. Pavers should drain. Flat spots that hold water tell us the base has settled unevenly. It will keep getting worse.

AfterReplacement Cost & What’s Included
Here is what we tell Tampa families before we write anything down: a full home addition runs $45,000 to $130,000. An ADU runs $90,000 to $220,000. The Tremron hardscape portion of that – patios, walkways, driveways, retaining walls – typically runs $3,500 to $18,000 depending on square footage and what’s happening underground. You get a written price before any work starts, on every project. No crew shows up and discovers the price.
| Project Type | Tampa Installed Range |
|---|---|
| Home Addition | $45,000 – $130,000 |
| ADU Construction | $90,000 – $220,000 |
| Garage Conversion | $30,000 – $80,000 |
| Paver Patio Installation | $3,500 – $11,000 |
| Paver Driveway Installation | $7,000 – $18,000 |
| Driveway Replacement | $5,000 – $14,000 |
The range is driven by square footage, access for equipment, the condition of the existing base, and whether we’re tying into older Tampa structures. In neighborhoods like Seminole Heights, older lot lines and original foundations add a layer of care that matters. The written price includes the full scope: materials, labor, clean-up, and the 365-Day Done Right Promise. If something isn’t right after the job is done, we make it right.
DIY or Call Us?
You can spot the drainage problem yourself. Walk the perimeter of your Tremron surface after a rain and look for standing water, soft spots, or washout at the edges. You can also check whether your downspouts are directing water away from the pavers, not onto them. None of that requires a tool.
What you should not do is pull up pavers and re-lay them yourself. The base needs to be excavated, re-compacted in lifts, and graded. Get that wrong in Tampa’s sandy soil and you’ll be back out there in eighteen months doing it again. Same logic applies to retaining walls – a leaning wall holds back more weight than people think, and a wall that lets go during rainy season is dangerous. Call (850) 779-4017 and we’ll walk the site with you. We write it down before we start so nobody is guessing mid-project.
FAQs
A properly installed Tremron paver surface in Tampa lasts twenty to thirty years with basic joint maintenance. The paver itself rarely fails; what fails is the base, the joint sand, or the drainage around it.
Yes, in most cases. If the pavers themselves are intact, we can lift an affected section, rework the base, re-grade the surface, and re-lay the same Tremron product. If the base was never built correctly from the start, a full remove-and-reinstall is the honest answer.
Most Tampa additions run three to six months from first walkthrough to final inspection. ADUs often run five to eight months, depending on utility connections and permitting. We’ll give you a written timeline along with the written price, and we keep noise confined to the hours we said we would.
We order Tremron and Tremron-compatible hardscape materials directly for each project, and we maintain relationships with Tampa suppliers who carry the Highlands, Olde Towne, and Mega lines. We also work with KraftMaid cabinetry, Cambria countertops, and Silestone surfaces when the addition calls for interior finish work. Call (850) 779-4017 and we’ll tell you what’s available for your project this month.
