Dvele Home Additions & ADU: The West Palm Beach Owner’s Guide
Bradford Remodeling Co West Palm Beach installs and services Dvele home additions and ADU builds in West Palm Beach, with typical projects running $45,000 – $130,000 for additions and $90,000 – $220,000 for full ADU construction. Most Dvele-compatible addition projects in our pipeline are diagnosed, scoped, and priced within one site visit. The problem usually shows up the way most structural or envelope failures do: water where it should not be, separation at the seams, or a system that worked fine until the first big South Florida storm season tested it.
We are an independent contractor. We are not affiliated with Dvele, and we do not represent their warranty. What we do is match the right materials and trade work to the Dvele build spec so your addition or ADU performs the way it was designed to, in this climate, under these codes.
Which Dvele Models This Applies To
Dvele’s panelized construction system relies on precision-cut wall, floor, and roof panels that get assembled on site. When you need an addition or ADU tied into an existing Dvele structure, the compatibility question is not cosmetic, it is structural. Dvele builds across a range of floor plans and series lines, and the panel dimensions, anchor points, and utility chases vary by model and year. You cannot assume a standard stick-frame addition will marry cleanly to a Dvele envelope.
The first thing we do on any Dvele addition job is match the existing structure’s spec, and we start with these checkable details:
- Panel joint locations. Dvele panels have engineered seam patterns. An addition has to tie into those seams, not bridge them.
- Foundation and anchor compatibility. West Palm Beach sits on sandy, fast-draining soil with a high water table in many neighborhoods, from Northwood to Flamingo Park. Your addition’s foundation design depends on what the original Dvele slab or pier system is doing.
- Hurricane strapping and uplift hardware. Florida Building Code requires continuous load path hardware from roof to foundation. A Dvele panel connection is not the same as a conventional stick-frame connection, and the strapping spec matters.
- Utility chase alignment. Dvele panels route electrical and plumbing through pre-cut chases. An addition that misses those chases means cutting into finished panels, which is expensive and, done wrong, compromises the envelope.
On the OEM-versus-aftermarket question: for structural connectors, flashing, and waterproofing membranes tied to the Dvele envelope, we use materials that meet or exceed the original spec, sourced from the manufacturers Bradford works with across the Garrison Partners network, including GAF and James Hardie for exterior envelope products. For interior finishes, fixtures, and cabinetry, we install the documented brand roster: KraftMaid, Cambria, Kohler, Moen, and the rest. You’ll know every material before it goes in, and the price is written down before work starts.

Signs Your Dvele Home Additions & ADU Is Failing
These are the five most common failure signs we see on Dvele addition and ADU projects in West Palm Beach, along with what each one means:
- Water staining at panel seams or along the roofline. When a panel joint loses its seal, wind-driven rain from a summer squall finds it fast. This is usually a flashing or sealant failure, but it can also mean a seam was not compressed properly during the original installation.
- Visible gap or separation between the addition and the main structure. Differential settlement is real here. Sandy soil plus seasonal moisture swings means a slab can move fractions of an inch. If your addition was not tied with the right connectors, that movement shows up as a crack at the transition.
- Doors or windows that stick seasonally. A panelized system should stay dimensionally stable. If a door in the addition binds in August but swings fine in January, the foundation or the panel connections are shifting more than they should.
- Condensation or dampness inside wall cavities near the panel joints. This points to a vapor barrier or air sealing problem. In Florida humidity, trapped moisture inside a wall assembly turns into mold faster than most people expect.
- Higher cooling bills after the addition is complete. A properly sealed Dvele envelope is tight. If your AC is running harder after the addition, the thermal break between old and new is not doing its job, and that means air is leaking.

AfterReplacement Cost & What’s Included
For a Dvele home addition in West Palm Beach, the installed range is $45,000 – $130,000. ADU construction runs $90,000 – $220,000. The spread is driven by square footage, foundation work, panel integration complexity, utility runs, and finish level. A garage conversion under a Dvele roof is typically $30,000 – $80,000.
Here is how the pricing breaks down on a typical mid-range Dvele addition:
- Foundation and slab work: $8,000 – $25,000 depending on soil conditions and pier requirements
- Panel tie-in, framing, and rough carpentry: $12,000 – $35,000
- Roofing and waterproofing integration: $6,000 – $18,000
- Electrical, plumbing, and HVAC rough-in: $7,000 – $22,000
- Drywall, finishes, flooring, and fixtures: $12,000 – $30,000
Every line item is written down before the first tool comes out. If something changes in the field, Curtis Lane calls you before touching it. The 365-Day Done Right Promise covers the completed work for a full year: if anything we installed fails inside that window, we come back and fix it at no charge.
DIY or Call Us?
This is not a parts-swap situation, and I want to be direct about that. A Dvele addition or ADU involves structural connections, foundation work, and building envelope sealing. If any of those are done wrong, you are not dealing with a cosmetic problem, you are dealing with water intrusion, mold, or a structural failure during a hurricane. The high-tension and load-bearing components here are not things a homeowner should be touching themselves. That is not gatekeeping. That is Florida Building Code and common sense.
What you can safely do is document what you are seeing: photos of the seam or crack, notes on when it appears, and any changes in your utility bills. That record helps us scope the job faster and price it accurately. Then call (728) 203-9809. We will send a background-checked, uniformed technician to walk the site, take measurements, and give you a written price. Straight number, full scope, no surprises after the invoice.
FAQs
A properly tied-in Dvele addition should last as long as the original structure, 50 years or more, provided the envelope is sealed correctly and the foundation is engineered for local soil conditions. The weak points are the transitions: the panel seams, the roof tie-in, and the slab joint. Those are where the Florida climate attacks first, and those are exactly the details we inspect on every job.
In most cases, yes. If the issue is flashing, sealant, or settling at a transition point, we can often correct it without tearing out the addition. The repair might involve re-flashing the roofline, injecting or reinforcing the slab connection, or re-sealing panel joints. If the panel structure itself is compromised, partial panel replacement becomes the conversation. Call (728) 203-9809 for a free estimate, and we will tell you what is actually needed, not what is easiest to bill.
A typical Dvele-compatible addition runs 6 to 14 weeks from permit approval to final inspection. The timeline depends on city of West Palm Beach permit review, which moves at its own pace, and on the extent of foundation and panel integration work. We pull the permits, we schedule the inspections, and we keep the site clean at the end of every day.
We keep a truck stock of the fast-moving envelope and tie-in materials: the flashing, sealants, connectors, and strapping we use on most Dvele integration jobs. Panel-specific and model-specific components are ordered to match your existing structure’s spec, which is how we make sure the addition performs correctly. Materials are sourced from the same documented manufacturer roster we use across all Bradford projects.
