Dvele Garage Conversion Contractor in Austin: What to Know First
We convert Dvele garages into finished living space across Austin, and most projects move from first measurement to final inspection in six to nine weeks depending on scope, plumbing, and how Austin’s permitting office is running that month. You get a written price before any work starts, and every conversion is backed by our one-year written guarantee. If you own a Dvele home and you’re weighing a garage conversion, this page tells you what to expect, what it costs, and how we keep the job from drifting. Call (361) 309-9568 and a live person picks up, day or night.
This page is for Dvele homeowners in Austin who want their attached or detached garage turned into a bedroom, ADU, apartment, or living space. If that’s you, Reed Calloway and our crew have worked these structures before. We know where they get tricky, and we know how to keep the conversion clean.
How Dvele Products Fail, and How We Fix Them
Dvele builds panelized, factory-cut homes with tight tolerances. That’s good for energy performance, but it creates a specific set of friction points when you convert a garage. Here’s what we see in Austin:
- Air-sealing membrane conflicts on partition walls. Dvele homes ship with continuous air barrier detailing that runs through the garage shell. When you cut a new door or window opening into the main house wall, you can break that seal if the contractor doesn’t know how to flash and tape it back to Dvele’s spec. We’ve opened walls on Dvele garage conversions started by other crews and found condensation staining behind the drywall within a season. Our fix is to re-tie the membrane before insulation goes back in, not after.
- Factory-installed electrical home runs pass through the garage ceiling. Many Dvele models, including the larger series homes we’ve converted off South Congress and in Mueller, route main panel feeders and branch circuits through the garage overhead. A careless conversion can bury a junction box above new drywall, which violates code and sets up a service nightmare later. We map every circuit before framing, and we move or terminate every box where it stays accessible.
- Pre-cut panel seams at garage slab edges don’t tolerate shimming. Dvele wall panels are milled to fit a near-perfect slab. Austin’s expansive clay moves garages over time, and we regularly see a quarter-inch of slab heave at truck door edges six or seven years after install. Any new partition that ties into a heaved edge needs a slip detail, not a hard connection, or the drywall cracks at the seam within months. This is one of the most common callbacks we fix from earlier Dvele conversion attempts.
- HRV ducting is quieter than conventional systems but harder to extend. Dvele’s balanced ventilation systems run at low velocity. When you convert a garage into a bedroom, you need to extend supply and return into that space. Off-the-shelf flex duct glued to the existing HRV manifold will starve the room and unbalance the whole home. We size the extension to the HRV’s static pressure budget, using rigid duct where the run exceeds twelve feet.
- Garage door rail and opener removal leaves structural brackets embedded in Dvele’s shear walls. Dvele’s side walls carry more lateral load than a typical stick-framed garage, so the brackets anchoring the door rails and torsion spring are usually oversized and through-bolted into the panel framing. Removing them incorrectly leaves holes that compromise the shear panel. We patch to shear spec, not just cosmetically, and we document it for your records.
Our Dvele Garage Conversion Contractor Process
- 1
Walk the garage and measure. Reed or a senior lead visits your Austin property, checks slab level, ceiling height, existing electrical, plumbing access, and Dvele panel condition. We photograph everything.
- 2
Written scope and price. The full job goes on paper before any work starts: framing, insulation, drywall, electrical, HVAC extension, flooring, paint, door and window changes, permit line items. The number you approve on day one is the number on the final invoice.
- 3
Permits and plan review. We pull permits with the City of Austin and handle any corrections. For detached garage conversions to ADUs, we confirm setback and utility routing early so nothing stalls at inspection.
- 4
Build and inspect. Our crew is background-checked and uniformed. We frame to our own conversion details for Dvele panel construction, run the mechanicals, and call inspections at the right moments so we’re never waiting idle.
- 5
Test and walk through. We check temperature drop across the converted space, look for any drywall movement at panel seams, and run every circuit. You walk the space with us before we call it done.
- 6
Written guarantee. Your one-year guarantee comes on paper: what it covers, how long it runs, and exactly what we do if something fails.
What Dvele Garage Conversion Contractor Costs in Austin

In Austin, a Dvele attached garage conversion to a bedroom or living space typically runs $68,000 to $112,000 before permit fees, depending on square footage, plumbing additions, and how much HVAC work the build requires. A detached garage conversion to a full ADU with a bathroom and kitchenette usually lands between $135,000 and $210,000, with the spread driven by utility trenching, panel upgrades, and finish level. A simple garage-to-bedroom conversion without plumbing can start around $55,000 if the electrical panel has capacity and we’re not cutting new exterior openings.
What moves the price: adding a bathroom, upgrading your electrical service, extending the HRV system, leveling a heaved slab, and any structural patching to Dvele shear walls. We price all of it in writing before we start. Call (361) 309-9568 for a free estimate on your specific garage.

FAQs

It can, if the conversion is done carelessly. Any modification that alters Dvele’s panel framing or air barrier can affect portions of the original manufacturer warranty on those components. The best way to protect yourself is to work with a contractor who documents everything, pulls permits, and builds to code. As an independent Dvele service provider, we don’t file warranty claims for you, but our written one-year guarantee stands behind our conversion work regardless of how Dvele’s warranty terms shake out. Call (361) 309-9568 and we’ll walk you through the specific details of your home before any decisions get made.
Most attached garage conversions run six to nine weeks from start to final inspection. Detached conversions to full ADUs run longer, typically ten to fourteen weeks, because of utility trenching, separate metering questions, and the extra plan review the City of Austin requires. We give you a written schedule with your written price, and we hold ourselves to both. Call (361) 309-9568 for a project-specific timeline.
Yes. Dvele’s interior palette is fairly standardized, so we can match drywall texture, paint, flooring, and trim closely enough that the converted space reads as original to the house. Where Dvele used factory-applied finishes we can’t source, we tell you before pricing so there are no surprises at walkthrough. Call (361) 309-9568 and we’ll bring finish samples to the estimate.
Always. Garage conversions in Austin require building permits, and detached conversions to ADUs also require zoning and utility approvals. We pull every permit, post them on the job site, and call inspections at the right time so the work passes legally. No permit, no exception. That’s part of The Garrison Code: by the book, every time.
Call us. The Garrison Standard covers workmanship defects for 365 days from completion. If something fails inside that year, we return and correct it at no charge. The terms are written on your guarantee before the job starts, so you know exactly what’s covered and how we make it right.
