Dvele Construction in Pomona, CA | Sycamore Contractors
We’re an independent Dvele construction partner serving Pomona and the surrounding San Gabriel Valley. Our crews assemble Dvele panelized walls, floors, and ADU packages on real Pomona lots – infill parcels, tear-down footprints, and century-old foundations that a factory drawing never accounted for. If you’re planning a Dvele build in Pomona, call (877) 265-6284 for a free estimate and a straight answer about whether your site can support a panel system without a fight.
Full transparency: we are not a Dvele dealer, and we aren’t authorized by the manufacturer. We’re the crew that shows up after the panels arrive, and the crew that fixes what the factory detail missed. That matters in Pomona, where the ground moves and the wind blows harder than most panel manufacturers expect. Nate Calloway, our owner, has spent his career making prefab systems work on lots that weren’t drawn in a CAD file – and Pomona has plenty of those.
Why Pomona Residents Choose Us for Dvele Service
Dvele builds a genuinely good panel system. But a panel system is only as good as the site it’s set on, and Pomona’s older neighborhoods push those systems hard. We’ve assembled Dvele packages on flat suburban lots and on 1920s bungalow additions in Wilton Heights, and the difference between those two jobs is the whole game. A crew that only knows the factory script gets in trouble fast on Pomona’s pre-war foundations.
What sets us apart is honest sequencing. Before a single Dvele panel comes off the truck in Pomona, we’ve already walked the foundation with a level, reviewed the soil report, and pulled the city’s retrofit requirements. That’s not extra work – it’s the actual work. On Dvele builds where the foundation sits out of tolerance, we bring in an engineer-specified leveling curb before panel set, because chasing settlement after the envelope is sealed costs triple. For Pomona homeowners considering a Dvele sales & service project, we’d rather have the hard conversation early than the expensive one later.
We also stock the consumables that keep Dvele builds moving: proprietary connection hardware, spec-matched sealants, and envelope tape. Not every part, but enough to avoid the two-week factory lead time on the common items. That’s the practical difference between a crew that works on Dvele occasionally and a crew that works on Dvele in Pomona regularly.

Common Dvele Construction Problems We Solve in Pomona
- Panel joint separation at floor-to-wall connections. Pomona’s expansive clay soils swell in winter rain and shrink in summer heat, which causes differential settlement the factory detail doesn’t anticipate. We’ve seen Dvele panel seams open up enough to break the air barrier within two years. The fix usually means re-leveling the interface, re-torquing connection hardware, and re-flashing the joint – not just caulking over the crack.
- Water intrusion at roof-to-wall transitions. Santa Ana winds drive rain sideways in Pomona. A Dvele envelope is tested for that, but field-cut penetrations are the weak link. When a vent or conduit gets cut on site and flashed by a crew that doesn’t understand Dvele’s seam taping sequence, water finds a way in. We re-flash every penetration we touch and verify the roof-to-wall transition against Dvele’s spec before anyone signs off.
- Rough-opening misalignment on additions. When a Dvele panel ties into legacy framing on a pre-1950 Pomona house, the panel’s rough openings don’t always line up with the existing structure. Forcing them to align compromises the sealed envelope. We field-verify every chase and opening before panels are set, and when misalignment exists, we modify the framing properly – not the panel.
- Foundation interface problems on 1920s concrete. Pomona’s older core has thousands of homes on original 1920s concrete foundations that are neither flat nor level within Dvele’s panel tolerance. Setting panels on that surface creates stress points that telegraph into the envelope. Our standard practice on those jobs is an engineer-specified leveling curb or retrofit before panel set.
- Compromised envelope after water-damaged panel exposure. Once water penetrates a Dvele panel and the structural core delaminates, the panel is done. We don’t chase those with patch kits. An honest repair-vs-replace call usually favors replacement, because a compromised envelope panel will haunt you for the life of the home in Pomona’s heat and wind cycles.
Dvele Service in Pomona: What Local Conditions Mean for Your Equipment
Pomona sits at the eastern edge of Los Angeles County where the San Gabriel Valley meets the Inland Empire, and much of its buildable land is already spoken for. That’s the quiet fact that shapes every Dvele job here. A Dvele panel package in Pomona almost always lands on an infill lot or a tear-down footprint – set against existing property lines, shared driveways, and neighbor setbacks that a greenfield build never has to solve. We’re moving panels with a crane over a 1920s Craftsman’s roofline, not staging them across an empty field.
The older housing stock compounds this. In neighborhoods around downtown (the 91766 and 91767 ZIPs), we routinely find original redwood sill plates and 1920s concrete foundations that predate modern seismic codes. Those conditions require engineer-specified retrofits before any Dvele addition can be permitted. The panel system itself is fine – it’s the interface between a 2026 factory panel and a 1924 foundation that needs the engineering attention. That’s the information a generic Dvele brochure won’t give you.
Dvele Models & Products We Service in Pomona
We work across the Dvele platform: their standard panelized wall and floor systems, modular single-family packages built to the high-performance envelope spec, Dvele ADU packages, and panelized additions for tight urban lots. The jobs we see most in Pomona are ADUs on infill parcels and panelized additions tied to existing pre-war homes.
Parts-wise, we source Dvele’s proprietary connection hardware, sealants, and replacement envelope components through the manufacturer and spec-matched suppliers. We don’t substitute aftermarket hardware just because it’s cheaper – it has to meet or exceed the original performance spec. For older Dvele assemblies with settled or water-damaged panels, we give a straight repair-vs-replace call. Spot repairs make sense on isolated joint failures. A panel with structural delamination or a broken envelope usually costs less to replace than to chase.

FAQs – Dvele Construction in Pomona
Yes, with the right foundation retrofit. Most pre-1950 homes in Pomona sit on concrete or pier-and-beam foundations that are neither flat nor level within Dvele’s panel tolerance. We bring in an engineer to spec a leveling curb or seismic retrofit before panel set, then install the Dvele panels to that corrected interface. It adds cost and time upfront, but it prevents joint separation and envelope failure later. Call (877) 265-6284 for a site assessment – we’ll tell you in one walk what your foundation needs.
Pomona’s expansive clay soils drive differential settlement, and the city’s building department enforces current seismic standards even on older existing structures. When a Dvele panel system ties into a pre-war home, the seismic retrofit of the existing foundation is typically triggered as part of the permit. That’s a Pomona-specific reality a panel manufacturer’s standard detail doesn’t address. We handle the retrofit engineering as part of the project.
Yes, and it’s most of what we do in Pomona. Infill ADUs on lots with shared driveways, narrow setbacks, and overhead utility conflicts require crane planning and sequencing that a standard drop-and-set crew won’t manage. We handle the logistics, the permits, and the panel assembly as one scope. Pomona service area coverage includes the 91766, 91767, 91768, and 91769 ZIP codes.
Not if it’s sealed and flashed correctly. Dvele’s high-performance envelope is designed for exactly those conditions, but field-cut penetrations and roof-to-wall transitions are the weak points. In Pomona, wind-driven rain finds any unflashed joint fast. We verify every penetration and transition against Dvele’s spec before close-out. For an envelope inspection or repair, call (877) 265-6284.
No. We’re an independent general contractor that builds and services Dvele panel systems. That independence is the point. Every Dvele project we take on gets our own engineering review, our own permitting legwork, and our own site-specific detailing – not a factory script applied blindly. If you’re looking for a Dvele sales & service partner who will tell you when the standard detail won’t work on your Pomona lot, that’s us.
