Tremron Home Additions & ADU: The Orlando Owner’s Guide
A Tremron home addition or ADU in Orlando typically runs $45,000 to $130,000 installed, and the parts we see fail first are nearly always at the connection points: the ledger board against the main structure, the roof tie-in flashing, and the sill plate where wood meets Tremron’s concrete paver or block base. Most owners discover a problem the same way: a soft spot in the floor, a door that suddenly sticks in summer humidity, or water staining on the interior wall where the addition meets the original house. Sawyer Remodel Orlando can source or fabricate the right Tremron-compatible components and have the repair quoted in writing before anything gets torn open.
We’re an independent general contractor, not a Tremron factory arm, which means we’ll tell you straight when a part should come from Tremron’s spec sheet and when a quality aftermarket equivalent gets the job done for less. Luca Romano has torn apart enough of these additions across Orlando to know which corners hold up and which ones Florida weather punishes first.
Which Tremron Models This Applies To

Tremron’s home addition and ADU components fall into a few categories depending on how the project was originally built: concrete paver base systems, precast concrete block, and their segmental retaining wall units that often support grade-level additions. The critical compatibility check is the connection hardware: Tremron block coursing (typically 8-inch nominal) dictates the anchor bolt patterns, and the ledger board spec varies by the block’s solid-web configuration. If your addition sits on a Tremron paver base, the parts that matter are the edge restraints and the compaction layers beneath the sill, not the pavers themselves.
To identify what you have, look for a stamped code on the underside of any exposed block or on the original permit set. Many Orlando additions built after 2010 using Tremron Turin or Lafitt pavers under a slab have specific load ratings stamped on the pallet ticket and sometimes on the block itself. Match that to the addition’s intended dead load and you’ll know whether the part you’re replacing is structural or cosmetic. OEM matters most around engineered connections: lintels, anchor straps, and any embedded tie. Aftermarket is usually fine for sill gaskets, flashing, and non-rated trim, as long as the material spec (gauge, coating, and profile) matches what’s already there.

Signs Your Tremron Home Additions & ADU Is Failing
- Soft spots in the floor near the original exterior wall. This is almost always moisture getting between the Tremron base material and the subfloor. In Orlando’s wet season, a failed sill gasket wicks water under the plate and rots the bottom plate from the inside out. You feel it before you see it.
- Horizontal cracking in the mortar joints where the addition block meets the house. Differential settlement between the foundation and the addition’s Tremron base shows up as stair-step cracks in the joints, not the blocks themselves. That’s the structure telling you the base is moving.
- Rust staining dripping from any embedded steel connector or strap. Central Florida humidity demands galvanized or stainless connectors. When a builder used plain steel to save fifty bucks, the rust marks appear within a few years and the bracket loses section fast.
- Doors and windows that stick in August but work fine in January. Orlando’s humidity swings cause expansion. If the addition’s roof tie-in wasn’t flashed with movement in mind, the frame binds and the drywall cracks at the corners each summer.
- A dark mold line forming where the addition’s slab or block meets the finished wall. This is the ledger board wicking ground moisture up. Left alone it becomes a structural issue and an air quality problem. In Orlando, it never dries out on its own.

AfterReplacement Cost & What’s Included

Full Tremron home additions and ADU projects in Orlando run $45,000 to $130,000 depending on square footage, whether you’re building on a paver base or pouring a new slab, and how much of the original tie-in needs rework. A smaller repair, like replacing a failed sill plate on one wall, usually lands in the $2,000 to $6,000 range once we open the wall, treat the framing, and close it back up with new flashing. Rebuilds of the roof tie-in hover between $4,000 and $9,000 depending on slope and roofing material.
Every quote goes to you in writing before work starts. That number is the number: parts, labor, haul-away, and the permit if one’s required in Orange County. We don’t run change orders unless you ask us to change scope. And every repair carries the 365-Day Done Right Promise: if it’s not done right, we make it right, in writing, on every job.
DIY or Call Us?
You can safely check a few things yourself: walk the addition’s perimeter and look for cracks wider than an eighth of an inch, run your hand along the base plates for soft wood, and clear any debris blocking weep holes or drainage channels. That’s inspection, not repair. The moment a Tremron base system needs work, forget DIY. Cutting into block, removing a ledger board that’s carrying roof load, or re-tensioning embedded anchors without knowing the original engineer’s spec is how small problems become surgical bills. We’ve pulled more than one homeowner out of a hole that started as a “I watched a YouTube video” Saturday project.

FAQs

A properly built Tremron-based addition in Central Florida should last 50-plus years structurally, but the connection hardware (sill gaskets, flashing, anchor straps) typically needs evaluation every 10 to 15 years because Orlando’s heat and humidity age those materials faster than the block itself. Call (850) 809-0306 and we’ll inspect that connection line before it becomes a repair.
Yes, in most cases the failing part is isolated to the connection points, not the Tremron material itself. Replacing a sill plate, re-flashing the roof tie-in, or re-anchoring a ledger is routine work. We’ll give you a written price for the exact repair before anything starts.
How long does a home additions & ADU repair take?
Small connection repairs take two to four working days including inspection and finishing. Full additions and ADU builds run eight to sixteen weeks depending on size and permitting in Orange County. We give you the schedule in writing before work begins.
Do you stock Tremron home additions & ADU parts locally?
We keep common sill gaskets, flashing profiles, anchor straps, and Tremron-compatible base materials on our trucks, and we can source OEM Tremron components from Orlando suppliers within one to three business days. No waiting weeks for a part that should already be here.
