Dvele ADU Builders Nationwide

Dvele ADU Builders in San Jose: What to Know First

We build, install, and service Dvele ADUs across San Jose as an independent Dvele service provider. Most Dvele projects we take on run 3 to 5 months from permit submittal to final inspection, depending on lot conditions and utility work. The price goes in writing before any work starts, and the same written price follows through to the final invoice.

How Dvele Products Fail – and How We Fix Them

• Envelope sealing around the marriage line on Dvele’s panelized models. Dvele ships units in large wall and floor panels that get joined on site. On the Dvele 320 and 420 series we’ve seen in San Jose, the factory-applied gaskets at those panel joints can degrade after two or three wet seasons. The symptom is damp drywall or a musty smell near the ceiling corners in winter. The fix is pulling the interior trim, replacing the gasket with a marine-grade seal, and re-flashing the exterior joint. It’s slow work, but it stops the water for good.
• ERP and smart-home sensor drift. Dvele’s platform leans hard on embedded sensors for air quality, humidity, and energy monitoring. In San Jose’s dry summers and damp winters, the humidity sensors can drift out of calibration. Owners see alerts that don’t match what a standalone hygrometer reads. We recalibrate or replace the sensor, and we don’t sell you a full re-commission unless the unit actually needs it.
• Panel joint settling on the Dvele 160 and 240 studio units. Lighter Dvele units on pier-and-beam foundations can settle unevenly in San Jose’s varied soils, especially in the Berryessa and Evergreen areas where clay content runs high. You’ll see a hairline crack along the interior panel seam, usually above a window or door. The root cause is foundation movement. We level the piers, then repair the seam with a flexible joint compound so it doesn’t re-crack on the next dry cycle.
• HVAC condensate routing on Dvele units with the factory ERV package. The energy recovery ventilator drains condensate through a small line that can clog with dust and mineral buildup. The first sign is water staining on the ceiling near the mechanical closet. We clean the line, check the drain slope, and install a larger diameter drain where needed. It’s a one-day fix that most manufacturers won’t cover under warranty because they classify it as maintenance.
• Exterior cladding attachments on Dvele’s larger Dvele 640 and multi-module configurations. When two or more Dvele modules join, the exterior cladding at the marriage line is site-applied. We’ve seen profile mismatches and loose fasteners there within 18 months on San Jose installations, especially on the south-facing elevations where daily thermal expansion is most aggressive. We re-secure the cladding, replace any warped sections, and seal the joint to match the factory finish as closely as the material allows.

Our Dvele ADU Builders Process

1. 1
   Site walk and measurement. We start on your lot, not on the phone. We check access, utility locations, setback lines, and the foundation or pad condition. If the Dvele unit is already on site, we inspect the existing panels, seals, and mechanical connections.
2. 2
   Written scope and price. You get a line-by-line scope with a fixed price before any permits are pulled. The number you approve on day one is the number on the final invoice.
3. 3
   Permits and city coordination. We handle the San Jose building permit, including any setback variance paperwork (the city’s written permission to build closer to the property line than the standard rule allows). We pull permits, schedule inspections, and stand on site for each one.
4. 4
   Foundation, assembly, and utility connection. We build the pad or footings to Dvele’s published foundation specs, then receive, set, and assemble the panels. Electrical, plumbing, and mechanical connections go in by the book, inspected at each stage.
5. 5
   Interior and exterior finish work. Drywall, trim, paint, flooring, cladding, and any site-built elements like decks or stairs. We match the factory finish where we can, and we’ll tell you plainly where we can’t.
6. 6
   Testing and walkthrough. We run every system, calibrate the Dvele sensors, and walk the unit with you before final inspection. Every Dvele project we build is backed by the Garrison Standard: a written one-year guarantee. If something fails inside that year, we come back and correct it at no charge.
