Why San Francisco Homeowners Choose Dvele ADU
We provide San Francisco Dvele service for independent ADU support, from panel gasket resealing and IQ sensor recalibration to full seismic tie-down inspection after the small tremors most people never feel but older wood-frame houses definitely register. As an independent Dvele service provider, we are not affiliated with or authorized by Dvele, but our crew has installed, leveled, and recommissioned Dvele’s panelized envelope systems on San Francisco hillsides and infill lots, so we understand the brand’s structural gaskets, mechanical chases, and sensor-driven commissioning steps from direct field work. If your Dvele ADU is showing signs of air leakage, sensor dropouts, or panel racking, call (424) 328-5746 and we’ll put the diagnosis and the fix in writing before a single tool comes off the truck.
Why Trust Benson ADU San Francisco for Your Dvele ADU?
Dvele builds a genuinely different wall and roof system than site-built framing, and servicing it well requires knowing how those factory-assembled panels are supposed to behave under Berkeley Dvele service conditions as well as San Francisco’s. Our lead builder, Troy Eastman, trained in construction technology at Los Angeles Trade-Technical College and spent years working through every phase of residential building before focusing exclusively on ADUs, including Dvele projects tucked into tight lots near Bernal Heights. That matters because a Dvele panel is not just lumber and sheathing. It is a steel-chassis structural component with embedded wiring chases, factory-installed gaskets, and sensor nodes that report back to the IQ gateway. When something feels off, you need a tech who can read both the physical panel and the building data, not someone who will poke at it with a moisture meter and shrug. We use factory-sourced steel connectors, panel gaskets, and IQ control boards for any structural or sensor work. We do not substitute knockoff structural parts on a Dvele. And like every project we take, the price is in writing before work starts, and a live person answers the phone around the clock.
Common Dvele ADU Problems We Fix in San Francisco
- Seismic tie-down plate loosening and panel racking. Dvele’s Steel Frame Series uses bolted tie-down plates at panel corners to keep the chassis rigid. After minor tremors, which San Francisco feels more often than most residents realize, those bolts can back off a few foot-pounds. The first sign is usually a hairline gap at an interior corner or a door that starts catching. We re-torque tie-downs to factory spec and check for panel racking before it becomes a structural issue.
- IQ sensor bus drops after power cycles. The Dvele IQ system is a real differentiator, but its humidity and CO2 nodes can fall off the bus after a PG&E line-voltage sag or a quick power flicker. When that happens, ventilation automations freeze and bedrooms go stuffy. We reflash the IQ gateway, replace failed PoE injectors, and rebalance the ERV so the system returns to automatic control without a full factory reset.
- Panel gasket compression set from fog and marine air. San Francisco’s fog belt, especially on the west side and in Potrero Hill, pushes moisture into every exterior seam. Over time, Dvele’s panel gaskets can take a compression set, meaning they flatten and stop rebounding, which lets air leak at roof-to-wall transitions. We inspect gasket condition with measured air leakage diagnostics and reseal or replace before condensation becomes mold inside the wall cavity.
- Drain-water heat recovery scaling from hard San Francisco water. Dvele’s mechanical package often includes a drain-water heat recovery unit, a copper coil that preheats incoming cold water using waste heat from shower drain water. San Francisco’s water is harder than most people assume, and mineral scale builds up on the coil over a few years, slowly dropping heat exchange efficiency. The owner notices the water heater working harder and longer. We descale the unit using manufacturer-safe procedures and restore efficiency without replacing the whole coil unless it has corroded through.
- ERV imbalance in foggy microclimates. Dvele ADUs ship with energy recovery ventilators that are commissioned at the factory for a generic climate profile. But San Francisco’s microclimates vary block by block. An ERV balanced for a dry inland morning will overcool a Richmond District unit on a foggy afternoon. We recalibrate humidity setpoints and airflow rates to match the actual conditions at your address, not the manufacturer’s default curve.
Dvele Parts & Our Repair-vs-Replace Approach
For Dvele envelope and chassis components, we use only factory-sourced parts: steel connectors, panel gaskets, IQ control boards. That is not a preference. Substituting an aftermarket gasket with a slightly different durometer can change how the whole panel system breathes, and a generic control board will not talk to the IQ gateway correctly. For generic mechanicals like pumps, valves, and thermostats, we install high-quality aftermarket equivalents when factory parts are backordered, and we always tell you which path we are taking and why. The repair-vs-replace decision is based on measured air leakage, sensor diagnostics, and the age of the component, not on what makes us a bigger invoice. If a panel can be resealed correctly, we say so. If the steel chassis shows cracking or the gasket channel is deformed, we quote panel replacement honestly. Call (424) 328-5746 for an exact quote, and we’ll put the parts and labor in writing.
Our Dvele Service Process – Step by Step
- 1
Diagnosis. We arrive in uniform, background-checked, and start with the IQ system logs and a physical inspection of panel seams, tie-downs, and mechanicals. If the IQ gateway has fault codes, we pull them before touching anything.
- 2
Repair or install. For gasket work, we remove the old compression-set gasket, clean the channel, and install factory-sourced replacement gasketing with the correct sealant bead. For sensor drops, we reflash the gateway, replace dead PoE injectors or nodes, and confirm each sensor reports back. For seismic work, we re-torque tie-downs and check panel alignment.
- 3
Test. Every repair ends with a functional test: blower-door numbers if air sealing was involved, sensor reporting verification, ERV airflow measurement, and a walkthrough of the IQ app with you.
- 4
Warranty. Every job carries our 365-Day Done Right Promise. If the same issue returns within a year, we come back and make it right, in writing.
Dvele Products We Service & Install in San Francisco
We service and install across the Dvele product family, including the Dvele IQ Whole Health monitoring system, the Dvele Steel Frame Series with its panelized structural chassis, the Dvele EQ seismic resilience package, and the Dvele Adaptive Panelized Envelope. We keep common Dvele gasket profiles, IQ PoE injectors, and steel connector hardware on hand locally so a diagnosis does not turn into a two-week parts wait. We also handle recommissioning for used Dvele ADUs where the original sensor and ventilation programming no longer matches the current floor plan, like a garage converted into a studio with different occupancy patterns.
We Also Service These Brands
Dvele is one of the strongest prefab systems on the market, but it is not the only one we know well. Our crew also services Abodu and Cover ADUs in San Francisco, which means we can give you an honest comparison if you are weighing brands, or switch seamlessly if your property has more than one prefab unit from different manufacturers. For other areas, see our Dvele in Vallejo coverage.
FAQs – Dvele ADU Service in San Francisco

No. We are an independent Dvele service provider, not an authorized factory service center. That said, our crew has installed, leveled, and recommissioned Dvele panelized systems across San Francisco, and we know the brand’s structural gaskets, mechanical chases, and IQ commissioning steps from direct field work rather than from a training manual.
For structural and sensor components, yes: factory-sourced steel connectors, panel gaskets, and IQ control boards. For generic mechanicals like pumps, valves, and thermostats, we install high-quality aftermarket equivalents when factory parts are backordered, and we flag the difference on your written quote before you approve anything.
Most single-issue Dvele repairs, like a dropped IQ sensor or a loosened seismic tie-down, are completed in one visit, usually four to six hours including testing. Larger jobs like full panel gasket replacement on a two-story unit can take two to three days. We give you a written timeline when we quote, not a vague “soon.”
We service the Dvele IQ, Steel Frame Series, EQ package, and Adaptive Panelized Envelope. That covers everything from sensor recalibration and ERV rebalancing to seismic inspection and envelope air-sealing, whether your unit is a backyard studio or a two-bedroom hillside build.
That is the right question to ask. If your Dvele ADU is still under factory warranty, we recommend you contact Dvele first for any covered defect. For out-of-warranty work or issues the factory will not cover, we use factory-sourced parts for structural and sensor repairs to protect the integrity of the system, and we document everything in writing. Call (424) 328-5746 if you want to walk through your specific warranty situation before scheduling.
Most ADU Builders charge variable rates, and our Dvele service calls in San Francisco run between $350 and $1,600 depending on what we find.
