Dvele Home Additions & ADU: The Orlando Owner’s Guide
Dvele home additions and ADUs in Orlando typically run $45,000 to $130,000 installed, depending on square footage, site prep, and how much of the existing structure we’re tying into. We work on Dvele-built homes throughout Orlando, and most owners call us after noticing water intrusion at the transition point where the original Dvele panel system meets the new addition, or when the HVAC load calc wasn’t redone properly and the new space never holds temperature. The good news: we diagnose the failure, write the price, and fix it right, with the number on paper before we pick up a tool.
Which Dvele Models This Applies To
Dvele builds panelized homes, which means the wall, floor, and roof sections arrive on site pre-fabricated and get craned into place. Additions and ADUs attached to these homes have to match the original panel dimensions and connection details, and that’s where we see most compatibility problems. The critical measurement is the panel-to-panel seam width and the specific weather barrier Dvele used on the original envelope. If your Dvele home was built before 2020, the exterior sheathing is likely a different spec than what the company ships now, so ordering a “Dvele-compatible” addition kit without checking the year of the original build is asking for a leak at the seam. We match the addition to the original panel profile, not just the model name.
Here’s what we check before quoting: the original build year, the panel edge profile at the connection point, the roof pitch and overhang depth (Orlando’s afternoon downpours punish shallow overhangs), and whether the existing foundation has the capacity for the added load. On the OEM-versus-aftermarket question: Dvele’s own panels are the cleanest match, but lead times from the factory can run months. For most Orlando owners, a properly engineered stick-built or SIP (structural insulated panel) addition tied in correctly performs just as well and lands inside the same price range, often with a faster start date.

Signs Your Dvele Home Additions & ADU Is Failing
- Water staining at the seam where the addition meets the original wall. This is the most common Dvele-specific failure we see in Orlando. The transition flashing wasn’t lapped correctly, and Orlando’s summer storms drive water behind the weather barrier.
- The new space runs 8 – 12 degrees hotter than the rest of the house. The original HVAC system wasn’t sized for the added square footage, or the duct run wasn’t balanced. You’ll feel it most in August afternoons.
- Cracking at the interior drywall joint along the connection line. Differential settling between the original slab and the new foundation. Florida’s sandy soils move, and if the addition’s footers weren’t engineered for the same bearing capacity, you get a visible crack right at the old-meets-new line.
- Doors and windows in the addition stick or won’t latch. The framing has shifted. In Orlando’s humidity cycle, lumber expands and contracts; if the addition wasn’t allowed to dry properly before drywall, you’ll notice it within the first year.
- Musty smell in the ADU after rain. Water is getting in somewhere, likely at the roof-to-wall connection or a window flashing detail. By the time you smell it, the moisture has already been sitting in the wall cavity.
Replacement Cost & What’s Included
In Orlando, full Dvele home additions land between $45,000 and $130,000. An ADU on a Dvele property runs $90,000 to $220,000. The spread comes down to four things: square footage, whether we’re matching the original Dvele panel system or engineering a conventional addition, site access for equipment, and the condition of the existing foundation. A garage conversion on a Dvele home runs $30,000 to $80,000, which is often the smartest way to add living space without touching the panelized envelope at all.
What you get with our price: a written number covering all labor, materials, permits, and dump fees, plus a written 365-Day Done Right Promise. If the addition or ADU fails inside that year, we come back and fix it at no charge. The price on day one is the price on the final invoice. Trevor Nash signs off on every Dvele-related estimate personally, because he’s spent enough time in College Park bungalows to know exactly what happens when someone cuts corners on a tie-in detail.

Honest answer: there is no safe DIY path for a Dvele addition or ADU repair. The work involves structural tie-ins, weather barrier continuity, and in many cases electrical and HVAC integration that requires permitting and inspection in Orlando. What you can do is document the problem: take photos of the seam, note when the water appears, mark the temperature difference between rooms. That information helps us quote accurately over the phone. What you should not do: cut into the panelized wall to “take a look.” You’ll compromise the air barrier, and you’ll likely turn a $1,200 flashing repair into a $12,000 envelope rebuild. If you see active water intrusion, call us at (850) 427-6454 and we’ll walk you through what to do until we get there.
FAQs
A properly tied-in addition on a Dvele home should last 50+ years structurally, but the connection details, flashing, and weather barrier typically need attention at the 10 to 15-year mark in Orlando’s heat and humidity. The original Dvele panels themselves are solid; it’s almost always the transition work that ages first.
Most failures can be repaired without teardown. Water intrusion at the seam, HVAC imbalance, and cracking at the drywall joint are all fixable if caught before rot sets in. The exception is foundation failure, which happens when the addition’s footers weren’t engineered for Florida’s soil. Call (850) 427-6454 and we’ll tell you honestly which situation you have.
A garage conversion typically takes 6 to 10 weeks. An attached addition runs 10 to 16 weeks depending on permitting, inspections, and scope. An ADU is a 4 to 6 month project. We’ll give you a written schedule before we start, and we show up in the window we gave you.
We source everything. For Dvele-specific projects, we’re an independent service provider, not affiliated with Dvele, but we have working relationships with engineered panel suppliers and can match or better factory lead times in most cases. We also work with trade brands like KraftMaid, Cambria, and Silestone for finishes inside the addition, so you’re not stuck with a short list.
