Dvele Garage Conversion ADU: The San Jose Owner’s Guide
Fielding ADU San Jose stocks and installs Dvele-compatible garage conversion hardware, fasteners, seal systems, and enclosure components, with most parts on the truck and installed in one visit. Typical replacement work on a Dvele garage conversion in San Jose runs $240 to $1,100 for parts and labor, depending on which component failed and how much access work is involved. Homeowners usually discover the problem the same way: a door that no longer seals, a floor-to-wall joint that has opened up, or a smell that says moisture got somewhere it shouldn’t have.
We’re an independent service provider in San Jose, not affiliated with Dvele, but we’ve worked on enough of their units to know exactly what to look for. Reed Calloway and the crew have pulled apart Dvele panels in Willow Glen, Cambrian, and over near Santana Row. The failures are consistent, and the fixes are usually straightforward once you know the part number.
Which Dvele Models This Applies To

Dvele builds their units as factory-made modules that get assembled on site. The garage conversion components we service span the panels, perimeter gaskets, through-wall utility penetrations, and the transition hardware where the Dvele module meets the existing garage slab and framing.
The part you need depends on which Dvele chassis you have and when it was built. Early Dvele units, roughly 2019 through 2022, used a clip-and-gasket system at panel joints that we still match today; later builds shifted to a different seal profile that is about 3mm wider and does not interchange. If you can read the label, check the interior module tag inside the electrical closet or the mechanical chase. The serial will start with “DV-” followed by four digits. Take a photo of that tag before you call, and we can usually identify your exact spec before we roll the truck.
OEM versus aftermarket matters on this part class. Dvele hardware is machined to tight tolerances and sourced in small runs, which means availability can be slow and prices run higher. For seals, gaskets, and non-structural fasteners, there are solid aftermarket equivalents that meet or exceed the original spec. For anything load-bearing, hanger brackets, panel anchors, or utility flanges, we recommend staying OEM. This is not where you want to save forty dollars.
Signs Your Dvele Garage Conversion ADU Is Failing
- Visible daylight at the floor-to-wall joint. The perimeter gasket has compressed or torn. In San Jose, this often starts on the east-facing wall where morning sun heats the panel and accelerates seal aging.
- Musty smell after rain. Water is wicking through a failed through-wall penetration seal and sitting in the sill channel. It doesn’t need to be a big leak to cause real damage.
- Draft you can feel with your hand near an outlet or light switch box. The utility penetration grommet has dried out and shrunk. Air moving through the wall cavity means the thermal envelope is broken.
- Panel-to-panel gap that has opened more than a quarter inch. The clip or bracket has shifted or loosened. Early Dvele units are prone to this on walls that carry a loft load or heavy cabinetry.
- Rattle or creak in wind. A panel anchor or hanger bracket has loosened. This does not fix itself, and ignoring it lets the panel drift further out of alignment.
Replacement Cost & What’s Included

For a Dvele garage conversion in San Jose, we price by the job, not by the hour. Here’s the range you’re looking at, installed, before any permit fees:
- Perimeter gasket replacement: $240 to $480. New seal profile, old seal removed, sill channel cleaned and insect-shielded.
- Through-wall penetration reseal (per penetration): $120 to $220. Done correctly with a compression grommet and perimeter sealant, not just caulk over the top.
- Panel clip or bracket replacement: $380 to $780. Includes alignment checks on the adjacent panel and torque verification.
- Full perimeter re-seal on a single Dvele module: $900 to $1,100. All gaskets, all penetrations, all tested with a smoke pencil before we leave.
The number on your written price is the number on the final invoice. That’s The Garrison Standard: price in writing before we start, and if the work fails inside 365 days, we come back and correct it at no charge. Reed’s take on this is simple: “Put it in writing, show up on time, build it right.”
DIY or Call Us?
There’s an honest split here. You can safely inspect your Dvele unit for the signs we listed above. You can take photos, check the serial tag, and feel for drafts. You should not open the wall cavities. Garage conversion ADUs carry plumbing, electrical, and structural connections behind the panels, and the last thing you want is to nick a wire or a water line while chasing a draft. Getting into a panel joint without knowing which fastener system you’re dealing with is how a $300 reseal turns into a $3,000 repair.
If you’re not sure what you have, call (669) 201-3984. We’ll ask for the serial number, we’ll tell you over the phone what we think it is, and we’ll give you the price before we schedule the visit. A live person answers, day or night.
FAQs

In San Jose’s climate, expect 6 to 9 years from original perimeter gaskets before compression set and UV exposure start to show. East-facing walls age faster, and units near the coast fall at the lower end of that range. Call (669) 201-3984 for a replacement quote.
Seals and gaskets cannot be meaningfully repaired; once the profile is compressed or torn, the fix is replacement. Panel brackets and clips can sometimes be re-torqued if caught early, but if the panel has drifted more than a quarter inch, replacement is the honest call.
Most Dvele garage conversion part replacements are done in one visit, typically 2 to 4 hours. A full perimeter re-seal on a single module takes about 6 hours including testing.
Yes. We keep common Dvele seal profiles, grommets, and bracket hardware on the truck, plus aftermarket equivalents where they hold up better. We also work with Abodu and Cover units, so we’re familiar with the differences between prefab systems and what fits what. Call (669) 201-3984 and we’ll confirm availability by serial number.
