Dvele Home Additions & ADU: The Orlando Owner’s Guide
Dvele homes are built differently than stick-frame construction, and adding onto one is not a standard remodel. In Orlando, a Dvele-compatible home addition typically runs $45,000 – $130,000, while a full Dvele-matched ADU starts around $90,000 and can reach $220,000 depending on size and site conditions. If you’re noticing water intrusion at the junction between your original Dvele module and an addition, delaminating panel seams, or HVAC zone imbalances that started after someone added square footage, you’re likely dealing with an addition or ADU that wasn’t matched to Dvele’s tolerances. Most Orlando owners discover the problem when humidity spikes inside the added space or when the original Dvele envelope shows stress at the tie-in point.
We’re Sawyer Remodel Orlando, an independent contractor serving Orlando and Central Florida since 2005. We’re not affiliated with Dvele. What we are is a crew that has cut into enough panelized, high-performance building envelopes to know what happens when an addition gets treated like a conventional frame-out.
Which Dvele Models This Applies To
Dvele’s home modules are factory-built with precision tolerances that stick-frame crews in Orlando rarely match. When an addition or ADU gets tied into a Dvele structure, the compatibility issue isn’t about a model number on a label. It’s about whether the new structure respects the original panel dimensions, the mechanical chases, and the air-sealing strategy Dvele engineered into the factory build.
This applies to Dvele’s single-family and multi-module homes, including any home built on Dvele’s panelized wall system with factory-applied sheathing and integrated utility routing. The way to identify what you’re working with: check the utility closet for the factory spec sheet or module layout drawing, often glued to the back of a panel or inside an electrical chase cover. Dvele homes also carry a serialized ID on the main electrical panel door or on a placard near the utility entry point. If you don’t have that sheet, we can usually identify the module boundaries by measuring from the exterior corner to the first vertical seam at 4-foot or 8-foot increments, since Dvele panels are made to those module widths.
On the OEM-versus-aftermarket question for Dvele additions specifically: there is no “Dvele addition kit” sitting on a shelf. Every tie-in is custom-fabricated to match the existing panel layout. The decision we help Orlando owners make is whether to match Dvele’s original panel specs exactly, or to use a high-performance alternative with equivalent R-value and vapor permeability. In Central Florida’s humidity, mismatched vapor profiles at the tie-in are what cause problems three years later.
Styles & brands we work with
Signs Your Dvele Home Additions & ADU Is Failing
- Condensation or staining at the tie-in seam. A properly matched addition flashes and seals the joint between old and new so the thermal break stays continuous. Staining means the air barrier was broken and humid Orlando air is condensing inside the wall cavity.
- HVAC zones far apart in temperature. Dvele’s envelope is tight enough that the HVAC was sized for the original volume. When an addition wasn’t matched, the system often can’t keep up, and you’ll see a 5 – 8 degree split between the original module and the new space.
- Cracks at interior corners of the added room. Stick-frame additions move at different rates than Dvele’s engineered panels. Movement shows up fastest at drywall corners and ceiling lines where the two structures meet.
- Higher humidity in the addition, year-round. A Dvele house breathes as a system. An unmatched addition without proper mechanical ventilation traps moisture. You’ll feel the difference, and a $20 hygrometer will confirm it: 65%+ while the original module holds 45 – 50%.
- Increased energy bills that never drop. If the addition created a leak in the original envelope or the tie-in wasn’t sealed to Dvele’s standard, the whole house works harder. Heat gain through a bad tie-in can add 10 – 20% to cooling costs in Orlando summers.
Replacement Cost & What’s Included
In Orlando, the installed cost for a Dvele-matched home addition runs $45,000 – $130,000 depending on the size of the addition, whether it’s a single-story bump-out or a second-story addition, and how much structural reinforcement the original module needs at the tie-in. A detached Dvele-compatible ADU starts at $90,000 and goes up from there based on square footage, utility runs, and site prep.
What you’re paying for: demolition and careful removal of the existing tie-in (when retrofitting a failed prior addition), structural engineering for the connection, framing and panel matching to Dvele’s module dimensions, air-sealing and flashing at every junction, insulation matched to the original envelope, drywall, trim, paint, and HVAC integration. Every job gets a written price before any work starts, so the number you approve is the number on the invoice. No change orders, no “we found something” at the end. That’s the Sawyer Remodel Orlando way under The Relay Visibility Guarantee.
Key takeaways for Orlando owners:
- Price range: $45,000 – $130,000 for additions; $90,000 – $220,000 for Dvele-compatible ADUs
- Written quote before any work starts, always, under The Relay Visibility Guarantee
- 365-Day Done Right Promise on every addition and ADU project

There is no safe DIY version of tying an addition into a Dvele panelized envelope. Cutting into the original envelope without understanding the panel layout, the air barrier, and the load path through the modules is how Orlando homeowners end up with a five-figure repair after a three-figure “cost saving.” The structural connection between old and new carries real load, and in hurricane-country wind zones, a bad tie-in is a safety problem, not just a performance problem.
What you can do safely: document temperature and humidity differences between the original module and the added space, check the tie-in seam for visible gaps or staining after a hard rain, and locate your Dvele spec sheet if you have it. That information helps us give you an accurate quote faster.

FAQs
A properly matched addition tied into a Dvele envelope with correct flashing, air-sealing, and ventilation should last decades in Orlando’s climate, with the same service life as the original modules. The tie-in is the weak point, not the addition itself, and that’s what we engineer most carefully. Call (850) 809-0306 if you’re seeing signs of tie-in failure.
Yes, in many cases we can repair the tie-in without full demolition, especially when the failure is in the flashing, air-sealing, or ventilation rather than the structure. We’ll open the junction, assess what’s actually failed, and give you a written price for the repair before we start. Estimates are free – call (850) 809-0306.
A single-story addition on a Dvele home typically takes 10 – 16 weeks from permit to final walkthrough, while a detached ADU usually runs 4 – 7 months including site work and utility connections. Permitting through Orange County adds time, and we pull every permit and pass every inspection. Call (850) 809-0306 for a project timeline based on your specific scope.
We don’t stock Dvele-branded panels because Dvele doesn’t sell retrofit panel kits to independent contractors. What we do stock and source are high-performance panel materials, flashing systems, and air-sealing products matched to Dvele’s specified performance, along with finishes from brands like KraftMaid, Cambria, and Silestone. Call (850) 809-0306 and we’ll put together a written quote with exact materials specified.
