Dvele Construction in San Jose, CA | San Mateo Construction
We’re an independent general contractor providing Dvele sales & service support across San Jose, and the short version is this: we build, install, repair, and retrofit Dvele’s panelized construction system on postwar tract lots, slab foundations, and the kind of tight urban infill sites that define San Jose. What sets our Dvele work apart here is that we plan every panelized addition and ADU around San Jose’s permit portal, historic-resource overlays, and the hidden wiring and footing issues hiding in 1950s-to-1970s stucco homes. We are not authorized by Dvele, and we don’t claim any partnership with the manufacturer. Call (855) 901-7266 for a free estimate.
Why San Jose Residents Choose Us for Dvele Service
Dvele’s system is genuinely different from stick framing: factory-built wall panels, pre-engineered floor and roof cassettes, and weather-resistive barrier pre-applied at the panel plant. That means the failure points are different too. Over the past decade we’ve learned where Dvele assemblies leak, where the connection hardware corrodes, and where the panel-to-foundation interface fails on slab-on-grade San Jose homes. Noel Carrington, our owner, grew up pouring concrete footings with his father in San Mateo and has spent nearly three decades on residential and light commercial jobs across the Bay Area. He’ll tell you what you actually need and won’t pad the bid with work that isn’t required. We carry factory-spec Dvele splines, tapes, membranes, and corrosion-rated connectors, and when factory parts are back-ordered we source documented equivalent-grade assemblies instead of whatever the supply house has on the shelf.

Common Dvele Construction Problems We Solve in San Jose
- Moisture intrusion at panel splines and tape joints. Dvele panels arrive with the weather-resistive barrier sealed at the factory, but after San Jose’s wet winters, those tape joints wick water into the wall cavity if the assembly wasn’t back-sealed on site. We see this on panelized additions and ADUs more often than on full Dvele home builds, because the field crew takes over more of the sealing work.
- Roof cassette ponding and edge-flashing leaks. Flat and low-slope Dvele roof cassettes hold water after a rainy December, and the resulting dry-rot in the fascia doesn’t show up until the first warm spring. Two wet winters is all it takes.
- Galvanic corrosion at panel-to-foundation hold-downs. When the factory hardware gets swapped for unrated fasteners during field assembly, the steel against concrete starts to break down. We replace with corrosion-rated connectors matched to the original Dvele load path.
- Thermal bridging condensation at panel-perimeter joints. On Dvele ADU and garage-conversion builds in uninsulated existing structures, the panel skins sweat, rust, and run moisture back into the interior cavity. It’s a slow failure, but it’s structural once it starts.
- Non-permitted additions blocking panel tie-in approval. The Dvele structure itself may be fine, but if the original San Jose house has an unpermitted sunroom or garage conversion, the city won’t sign off on the panelized addition until the old work is brought to current code.
Dvele Service in San Jose: What Local Conditions Mean for Your Equipment
Nearly every Dvele addition or ADU inquiry we get in San Jose lands in the 1950s – 1970s postwar single-family tract zone, which means the panelized structure has to tie into an existing slab-on-grade or pier-and-grade foundation whose original footings and hidden knob-and-tube or aluminum wiring have to be exposed and brought to code before a single Dvele panel can be signed off. That’s the part a generic Dvele page never tells you. In neighborhoods like Willow Glen, Buena Vista, and the Rose Garden, the same project often triggers San Jose’s historic-resource review and tree-preservation rules, so a simple kitchen bump-out becomes an arborist report plus design-review hearings before permits are issued. We plan the Dvele assembly around that paperwork, not after it. A Willow Glen homeowner had us build a panelized rear addition in a 1960s stucco-and-wood-frame tract house, and we found the Dvele panel spline tape had been weather-sealed at the factory but not back-sealed after the wet season. Water had been wicking into the wall for two rainy winters. We opened the assembly, replaced the failed membrane and anchor hardware, re-flashed the roof cassette, and the panelized addition went in true and dry with the stucco tied back in.
Dvele Models & Products We Service in San Jose
We service the full Dvele panelized line: the prefabricated wall panel system, pre-engineered floor and roof cassettes, high-performance wall assemblies with integrated weather-resistive barrier and rainscreen detailing, and modular/panelized post-and-beam addition packages. For repairs, we source OEM Dvele panel splines, tapes, weather-resistive membranes, and connection hardware from the factory whenever they’re available. When a factory part is back-ordered or the original spec isn’t recoverable from the home’s documentation, we switch to equivalent-grade exterior assemblies and corrosion-rated connectors, never uncertified hardware. Repairable panel-joint, flashing, and connection failures get fixed and re-sealed. When a panel’s structural skin or load path has gone soft, we replace rather than patch.

What drives the cost on a San Jose Dvele project isn’t just square footage. It’s the condition of the existing slab or crawl space, whether the electrical panel needs to be replaced for the added load, whether the site hits historic or tree review, and what we find when we open the walls. A free estimate from us includes a walk-through of those conditions and a written line-item scope, so you know what you’re paying for before you sign. Call (855) 901-7266 for exact numbers on your project.

FAQs – Dvele Construction in San Jose
Yes, but the slab has to be evaluated first. San Jose’s 1950s – 1970s tract homes typically have slab-on-grade or pier-and-grade foundations with original footings that were sized for a much lighter single-story house. We expose the existing footing at the tie-in points, confirm the concrete is intact and rated for the Dvele panel load, and bring any hidden knob-and-tube or aluminum wiring up to current code before the panelized structure is set. If you’re in Communications Hill or nearby, call (855) 901-7266 to schedule a foundation and electrical review with your estimate.
It often will. Older neighborhoods in San Jose, including Alum Rock, carry historic-resource overlays and tree-preservation rules that can require design-review hearings and arborist reports before the city issues permits. We prepare the Dvele panelized addition drawings and material specs specifically for that review, so the permit process moves as cleanly as possible.
Yes. San Jose’s permit portal flags any existing non-permitted work on the parcel, and the city won’t sign off on a new Dvele ADU or panelized addition until that old work is legalized or removed. We handle that scope as part of the same contract, which keeps the schedule and the permit package in one place.
We verify against the original Dvele assembly documentation for your panel system, and when that spec isn’t recoverable we pull the engineering data from the panel tags and site photos. Every piece of connection hardware we install is corrosion-rated and matched to the Dvele load path. We don’t substitute what the supply house happens to carry that week.
Plan on $53,100 to $153,400 for a panelized home addition and $106,200 to $259,600 for a Dvele ADU in San Jose, depending on site conditions, foundation work, and permit requirements. Garage conversions integrated with Dvele panels run $35,400 to $94,400. Call (855) 901-7266 for a written line-item quote; estimates are free.
