How Dvele Products Fail – and How We Fix Them
Dvele builds homes on a panelized system, not stick framing. That changes how a garage conversion has to be approached. Here are the failure modes we see on Dvele garage jobs in San Jose:
- Steel moment-frame settling at the garage header. Dvele’s structural system uses steel plates and moment connections at the garage opening. After a few seasons of Bay Area wet-dry cycling, the anchor bolts can work loose, and the header will drop three quarters of an inch. You’ll see a diagonal crack running from the upper corner of the garage door. We pull the anchor covers, torque the bolts to Dvele’s spec, and patch the fire-rated assembly before closing it up. A conventional GC will just caulk the crack and call it done. We don’t.
- HVAC mini-split condensation in the garage slab. Dvele specs the garage slab without a vapor barrier in some model years, which means the mini-split line sets condense inside the wall cavity during San Jose’s warm nights. On Dvele Series 2 and Series 3 homes, we see this in garages that never had insulation upgraded. The fix is pulling the bottom plate, adding closed-cell insulation to the first 12 inches of cavity, and re-flashing the penetration. It’s a two-day job that prevents mold and drywall rot.
- Panelized wall joint gapping at the garage-to-house connection. Dvele walls arrive as pre-built panels, and the joint where the garage panel meets the main living panel opens up over time. On colder mornings you’ll feel a draft at the baseboard. The cause is thermal expansion of the panel edge channels. We cut back the drywall at the seam, install a slip track with acoustic sealant, and re-tape. That’s a Dvele-specific fix; most San Jose GCs won’t know the panel layout well enough to find the seam quickly.
- Electrical chase routing that blocks ceiling work. Dvele runs a central wiring chase through the garage ceiling, which means a standard recessed-light layout will hit conduit. If a contractor doesn’t know the chase location before cutting, you end up with patched drywall or, worse, a buried junction box that won’t pass inspection. We map the chase before any ceiling work starts and route lighting around it.
- Garage floor slab elevation issues for ADU conversion. Dvele garages in San Jose are often poured flush with the driveway, which means converting one to living space requires raising the floor or adding a step-down entry. The city wants 6 inches of separation from exterior grade at the finished floor. We handle the concrete lift or the step-down design so the permit passes on the first submittal.
Our Dvele Garage Conversion Contractor Process
- 1
Call and walkthrough. Reed Calloway or a senior lead walks the Dvele garage with you. We look at panel seams, the moment frame, the slab height, and the electrical chase. This visit is free.
- 2
Written scope and price. Within the week you get a line-item written price. It includes permits, materials, labor, and the name of the inspector we’ll work with. No allowances, no “we’ll see.”
- 3
Permit submittal. We draw the conversion to San Jose code, including any setback variance if you’re adding a separate entrance. The city plan reviewer sees a complete package, not half a set.
- 4
Demo and structural work. We open the walls at the panel joints, verify the moment frame, seal the vapor barrier, and run the new mechanical and electrical around Dvele’s existing chases.
- 5
Finish work and systems test. We drywall, paint, set the doors and windows, and run the HVAC for a full cycle before final inspection.
- 6
Inspection and The Garrison Standard. We walk the job with you, hand you the written one-year guarantee, and make sure the site is swept and clean before we leave.
What Dvele Garage Conversion Contractor Costs in San Jose

Garage conversions in San Jose typically run $95,000 to $165,000 before permit fees, depending on square footage and whether you’re adding a bath or kitchenette. The Dvele-specific scope adds a few thousand dollars to the lower end because of the panel seam sealing and chase mapping we won’t skip, but the structural system is generally sound enough to avoid major reframing. Here’s the line-item view:
- Basic living space conversion, 400 square feet: $95,000 to $115,000
- Garage to bedroom with half bath: $120,000 to $140,000
- Full garage ADU with kitchenette and separate entrance: $150,000 to $165,000
- Permit and plan fees: $8,000 to $14,000, depending on San Jose’s current fee schedule
What moves the price is the bath count, the need for a slab lift, and whether the Dvele panel joints need structural re-torquing. We put it in writing before the work starts. Call (669) 201-3984 to get your free estimate.
Why San Jose Homeowners Call Fielding ADU San Jose for Dvele Work
Most of the calls we get in San Jose start the same way: the homeowner already has a bid from someone who doesn’t know Dvele, and the bid left out the chase mapping, the panel seams, and the slab separation. We’re not the cheapest bid. We’re the one that doesn’t move. The Garrison Code is how we operate: show up in the window, put the price in writing, build it by the book, leave it clean, and stand behind it for a year. Reed Calloway runs a crew of background-checked, uniformed techs, and someone answers the phone at 2 a.m. if you call. If the Dvele conversion shifts a panel or a seam opens inside 365 days, we come back and fix it at no charge.
FAQs

Modifications to structural panels or the moment frame can void portions of the original Dvele warranty for those components, which is why we document every change, torque to OEM spec, and leave the panel system intact wherever possible. We’re an independent Dvele service provider, not authorized by Dvele, and we’ll tell you honestly what your modification touches. Call (669) 201-3984 and we’ll walk you through it.
Yes. Dvele exterior panels use a proprietary cladding that can be order-matched through their supply partners, but it’s often a six-week lead time. We can match the finish from the existing panels using the same supplier or offer a James Hardie siding alternative that reads clean against the original. For an exact quote on your panel match, call (669) 201-3984.
Every garage conversion we do in San Jose is permitted, including the electrical, plumbing, and any setback variance the city requires. We hand you the completed permit record at final inspection. If a contractor tells you the permit can be skipped on a Dvele conversion, walk away. Call (669) 201-3984 to see a written scope with the permit line item included.
