Dvele Construction in Ontario, CA | Polaris Contractors
Dvele panelized homes go up fast, but they still answer to Ontario’s soil, heat, and wind long after the factory seals are in place. We’re Polaris Contractors, led by Rick Sondermann, and we provide independent Dvele construction service across Ontario’s 91758, 91761, 91762, and 91764 ZIP codes. What sets our work apart here is simple: we read Dvele’s assembly drawings directly and we know what Ontario’s former citrus-grove lots do to a foundation-to-panel connection. Call (855) 473-6535 for a free estimate on your Dvele build or repair.
Why Ontario Residents Choose Us for Dvele Service
We’ve spent years working alongside Dvele’s panelized, factory-built wall and roof assemblies, which means we’ve seen how their structural screw-together systems and weather-sealed panel joints actually behave once they’re standing in Ontario’s heat and Santa Ana wind cycles. Our crew coordinates site prep, foundation interface, and finish work to the tolerances those panels demand, and we source Dvele’s OEM structural fasteners, gaskets, and flashing profiles wherever they’re available. If a panel seam is going to fail, it usually fails where the factory seal meets the local climate, and we know where to look first.
Rick Sondermann grew up in Corona del Mar and has spent the better part of three decades building and renovating homes up and down the Southern California coastline. He learned the fundamentals of construction at Saddleback College in Mission Viejo, and the philosophy he brought from his father, a finish carpenter, still drives how we approach every Dvele project in Ontario: do it right the first time, because the second time always costs more. One team, full scope, from the roof down to the pavers.

Common Dvele Construction Problems We Solve in Ontario
- Panel joint weather-seal failures. Factory gaskets and flashing shrink and crack after Ontario’s hot, dry summers and Santa Ana wind cycling. When the seal fails, water gets behind the panel and the drywall tells you about it months later. We remove the failed gasket, verify the panel edge, and re-seal with the correct OEM profile.
- Differential settling at the foundation-to-panel sill plate. Dvele builds sit on expansive soils that dry and shrink fast in Ontario’s heat, and the result is drywall cracks at panel seams where the sill plate moves slightly. We diagnose whether it’s cosmetic movement or something structural, then re-level and re-torque as needed.
- Roof panel seam lifting under Santa Ana wind uplift. When edge flashing wasn’t sealed to spec at install, the wind gets underneath and backs fasteners out. We see this most often on two-story Dvele assemblies where the roof overhang catches the full force of a gust. Re-seating and re-sealing those seams is repair work, not replacement.
- Moisture intrusion at window and door penetrations. Ontario’s winter rain events follow long dry summers, and the panel envelope expands and contracts around every penetration. Caulked joints let go, finish delaminates, and water finds the gap. We pull the trim, inspect the flashing, and rebuild the weather barrier to the assembly drawing.
- Foundation surprises on former citrus grove lots. In the 91764 ZIP especially, old irrigation lines and pockets of organic debris under a new Dvele addition can undermine the slab. We over-excavate, recompact, and document everything the Ontario building inspector wants before the first panel goes vertical.
Dvele Service in Ontario: What Local Conditions Mean for Your Equipment
In the 91764 ZIP, many of the postwar lots where homeowners add Dvele ADUs or additions sit on former citrus groves. That’s not a footnote; it’s the most Ontario-specific factor in any Dvele build here. We hit old irrigation lines and pockets of organic debris under the surface, material that lets a new foundation settle unevenly unless it’s over-excavated and recompacted first. Ontario inspectors now push hard on soil reports and drainage plans for ADU permits, so we document everything. On a Dvele two-story panel assembly going up behind an older ranch home in the 91764 grove tracts, our crew found an old irrigation lateral and loose organic fill right in the footing line. We over-excavated and recompacted before setting the sill plate, then re-torqued the structural fasteners and re-sealed every gasket and flashing joint once the panels were standing. The homeowner passed the ADU inspection with the added soil documentation the city wanted. That’s the difference between building a Dvele here and building one somewhere without grove history.
Dvele Models & Products We Service in Ontario
We work on Dvele’s self-powered panelized wall and roof assembly packages, single-story and two-story modular home designs, net-zero-ready high-performance envelope series, and steel-and-wood hybrid structural panel systems. Our repair-and-replace stance is honest: we fix joint, flashing, and sill-plate issues first, and we only recommend panel replacement when a section’s structural integrity is genuinely compromised. For parts, we source Dvele’s OEM structural fasteners, gaskets, and flashing profiles wherever they’re available, because the panel system’s water and air seals depend on exact-fit components. Aftermarket substitutes are a last resort only when timelines force it. We keep the common gasket profiles and fastener sets in local inventory so Ontario service calls don’t wait on cross-country freight. Dvele sales & service through Polaris covers the full assembly, from base plates to ridge caps.

FAQs – Dvele Construction in Ontario
Yes. Most ADU permits in Ontario’s 91761 and 91762 tracts require soil documentation and drainage plans, especially where the lot was once agricultural. We handle the over-excavation, recompaction, and permit paperwork before the first Dvele panel leaves the factory, and we coordinate Dvele in Upland and throughout Ontario from foundation to finish. Call (855) 473-6535 for a free site evaluation.
They can, and it’s one of the most common Dvele failure modes we see in Ontario. The factory gaskets and flashing shrink and crack after repeated hot, dry summers and Santa Ana wind cycling. The good news is that seam-level issues are almost always repairable without replacing panels, if they’re caught before water intrusion spreads. If you see drywall cracks at panel seams, call (855) 473-6535 and we’ll diagnose it.
We use Dvele’s OEM structural fasteners, gaskets, and flashing profiles wherever they’re available. The panel system’s water and air seals depend on exact-fit components, and aftermarket substitutes are a last resort only when delivery timelines force a decision. We keep common profiles in local inventory so most Dvele repair in Chino and Ontario don’t wait on freight.
Yes, we do it regularly. Ontario’s 1950s – 1970s ranch homes are wood-frame, and a Dvele addition ties in at the roofline and foundation with careful flashing and transition detailing. We also account for the older home’s foundation movement, since the two structures will sit on different soil conditions and may settle at different rates, whether we’re working in Ontario or handling Dvele in San Antonio Heights. Call (855) 473-6535 to have us look at your roofline and foundation.
The big ones are old irrigation lines, pockets of organic debris, and loose fill that lets a new foundation settle unevenly. We see this most in the 91764 ZIP, where postwar lots were once groves. We over-excavate, recompact, and document the soil work so your Ontario ADU inspection goes through clean. Estimates are free, so call (855) 473-6535 and we’ll walk your lot with you.
