Dvele Construction in Palo Alto, CA | Bradford Remodeling Co San Jose
Dvele construction service in Palo Alto means working on a high-performance envelope inside a city that regulates every wall penetration, circuit, and roofline with unusual care. We’re Bradford Remodeling Co San Jose, an independent Dvele service provider serving Palo Alto homeowners who need envelope repair, ADU work, and whole-home remodeling on Dvele 100, 200, and 300 Series homes. Our crews understand the 9.25-inch wall assemblies, Zehnder ERV routing, and DveleIQ control boards, and we pair that with practical knowledge of Palo Alto’s reach code and historic overlays. Call (669) 272-2637 for a free estimate on your Dvele project.
Why Palo Alto Residents Choose Us for Dvele Service
Most general contractors in Palo Alto have never opened a Dvele wall. We have. Curtis Lane, owner of Bradford Remodeling Co San Jose, trained through the construction technology program at Los Angeles Trade-Technical College, where he learned to read structural drawings and run a job by the numbers, not by feel. That discipline matters on a Dvele home, where the continuous vapor barrier, service cavity, and rainscreen detailing mean every cut has consequences. We carry that hands-on knowledge to every Dvele sales & service call across Palo Alto, from Barron Park to Professorville. Our crews stock OEM Dvele items like Zehnder ERV filters and proprietary flashing tapes when lead times allow, and we’re straight about when a high-quality aftermarket part does the job without touching the envelope. For anything involving the vapor barrier, wall assembly, or DveleIQ control board, we lean toward repair before replacement. Straight number, written scope, done when we said done.

Common Dvele Construction Problems We Solve in Palo Alto
- Concealed sheathing rot behind the rainscreen. In Palo Alto’s wet winters, the continuous vapor barrier detail behind the rainscreen can trap moisture at the bottom plate on south-facing walls. We open the interior carefully, dry the cavity, seal the breach with Dvele-approved butyl tape, and reinstall sheathing before the rough inspection.
- Condensate pooling in Zehnder ERV ducts. The pre-plumbed ComfoAir ERV runs in Dvele homes often develop condensate at low elbows in unconditioned crawl spaces. That produces the earthy smell near supply registers in winter. We reroute or re-pitch those runs so condensate drains instead of pooling.
- DveleIQ lighting resets during PG&E voltage sags. Palo Alto gets its share of PG&E equipment switching, and the DveleIQ board is sensitive to local voltage dips. We diagnose whether it’s a hard reset issue or a deeper wiring fault, then correct it without hacking the smart system out of the wall.
- Triple-glazed tilt-turn window hardware losing sash tension. Years of daily use on older Dvele installs wears the European hardware. In Palo Alto’s mild, wet winters, that lets slight air leakage and moisture film form on interior frames. We replace gaskets and retune the hinge tension rather than pulling the entire window unit.
- Envelope breaches from prior appliance swaps. This is the expensive one. In the Barron Park neighborhood, our techs pulled the interior drywall off a Dvele 100 Series kitchen wall to find the original vapor barrier had been nicked during the owner’s prior appliance swap. We sealed the breach with Dvele-approved butyl tape, rerouted a 50-amp induction range circuit through the service cavity, and reinstalled the sheathing before rough inspection, no new envelope penetrations, no thermal bridging at the stud lines.
Dvele Service in Palo Alto: What Local Conditions Mean for Your Equipment
Palo Alto’s Reach Code requires all new low-rise residential construction, including ADUs on Dvele properties, to be all-electric with no natural gas piping. That rule changes how Kitchen Remodeling in Palo Alto works on a Dvele home compared to Sunnyvale or San Jose. Any kitchen remodel that touches the wall assembly must route new 240V circuits through the same 9.25-inch stud cavities without severing the existing service cavity or vapor barrier. In Professorville, the Single Story Overlay adds another layer: new second stories often need to be set back to preserve street views, which forces creative dormer and loft designs that still have to maintain the continuous insulation layer Dvele built in the first place. That’s a local constraint most contractors outside Palo Alto never face. Our crews plan around it from the first site visit.
Dvele Models & Products We Service in Palo Alto
We work on all four Dvele lines in Palo Alto: the DveleIQ smart-home platform, the Dvele 100 Series passive house-inspired prefab, the Dvele 200 Series mid-size single-family and ADU builds, and the Dvele 300 Series custom luxury builds with advanced envelope detailing. For critical envelope and mechanical components, we stock OEM Dvele parts when lead times allow, including Zehnder ERV filters and proprietary flashing tapes. For generic hardware like window gaskets and interior fixtures, we use high-quality aftermarket equivalents and tell you which is which. No guesswork, no mystery parts.

FAQs – Dvele Construction in Palo Alto
Yes, but only with careful planning. We design the second-story connection so the new framing ties into the existing structure without puncturing the continuous insulation. In Professorville, the Single Story Overlay also requires the new story to be set back, which actually works in our favor: less wall area means fewer envelope penetrations. Call (669) 272-2637 for a written plan and exact price.
The smell is condensate pooling at low elbows in the Zehnder ComfoAir duct runs, usually in unconditioned crawl spaces. New filters don’t fix it because the water is sitting in the duct, not the filter. We re-pitch the runs so condensate drains, and the smell clears. Call (669) 272-2637 for a diagnostic visit.
No. Palo Alto requires a separate foundation permit for any ADU, including one next to a Dvele home. What we can do is handle the full permit package through the city, including the all-electric reach code compliance, so you don’t end up with a stop-work order. Estimates are free, call (669) 272-2637.
It’s usually voltage sags during PG&E equipment switching. The DveleIQ board reads the dip as a fault and resets the lighting scenes. We can install a small line conditioner or reroute the board’s power supply so it stops dropping. Call (669) 272-2637 and we’ll diagnose it on the first visit.
Yes. We remove the sash and hardware from the interior without cutting into the wall assembly, then install the replacement unit from the inside. The vapor barrier stays intact. If the original install left a small breach, we seal it with Dvele-approved butyl tape before reinstalling. Call (669) 272-2637 for an exact quote.
