Dvele Construction in Pomona, CA | San Bernardino Contractors
We provide independent Dvele construction service across Pomona for modular homes, ADUs, and panelized additions, and we also offer General Contractor in Pomona support for related site work. What makes our Dvele work different in this city is the pre-construction piece nobody warns you about: Pomona’s older housing stock arrives at a Dvele project carrying unpermitted garage conversions and bootleg room additions that have to be legalized with the city before your new modular structure can even be permitted. If you’re dealing with a Dvele ADU in Pomona or planning one, call (855) 473-5620 to have us walk the property first.
We’re Dvele sales & service specialists with years working around panel-based assembly, factory-set tolerances, and the system interfaces Dvele modules demand. We know how these structures go together, we know what fails on them in Pomona’s heat, and we know what the City of Pomona is going to ask for before any modular work gets approved.
Why Pomona Residents Choose Us for Dvele Service
We are an independent Dvele service provider. That’s worth saying plainly: we are not authorized, endorsed, or partnered with Dvele. Our loyalty runs to the homeowner who needs a structure closed in, finished, and permitted correctly, not to a manufacturer’s warranty department. That independence means when we tell you a repair is a repair and not a replacement, you can trust the recommendation isn’t being driven by an OEM incentive.
Ruben Castillo, Owner at San Bernardino Contractors, grew up in San Bernardino’s Westside watching his uncle reroof houses and frame garages on a shoestring. He learned early that panel seams and load paths don’t forgive shortcuts. The crew here treats Dvele module-set work the same way we treat any structural job: check the factory tolerances, verify the weather barrier, document what’s actually there before we touch anything.
We serve the whole of our Pomona service area from the pre-war bungalows near downtown to the ranch homes up in the 91766 and 91768 zips. If it’s not built right the first time, you’re just paying for it twice.

Common Dvele Construction Problems We Solve in Pomona
- Stucco cracking at panel-to-panel seams. Dvele modules are factory-built to tight tolerances, but the thermal movement between panels in Pomona’s inland heat cycles is real. When the summer sun blasts the south-facing walls and Santa Ana wind events swing the temperature, the seams move. If the stucco wasn’t applied with proper joint treatment and a flexible transition at the panel break, you get vertical cracks that come back every year no matter how many times they’re patched. We remove the failed section, install the proper seam tape and lath, and re-stucco so it actually holds.
- Moisture intrusion at module-set joints and window flanges. A dry, high-UV Pomona summer cures flashing tape fast. If the field crew compressed or skipped the gasket during the set, water finds the gap. We diagnose these after the first winter rain when the drywall shows staining at the set joint. The fix is to open the wall from the exterior, reset the gasket, and reflash the flange with the factory-spec material, not whatever sealant was on the truck.
- Interior drywall and trim separation at set-point seams. Homeowners call this “the house settling.” It isn’t. It’s a module alignment or fastening issue from the day the modules were placed. When the factory-set alignment is off even slightly, the finished drywall at the ceiling and floor lines telegraphs it. We find the root alignment problem, re-secure the module connection, and repair the finish so it stays flat.
- Misaligned electrical and plumbing chases. Dvele modules ship with rough-in chases in fixed factory locations. Site trades sometimes have to fight a layout that was locked in before the foundation was even measured. We’ve realigned electrical and plumbing runs on Pomona ADUs where the factory chase didn’t line up with the site-built foundation. It’s tedious work but it has to be done before drywall goes on, or you’re chasing it for the life of the structure.
- Window flange failures from sun exposure. Pre-installed Dvele windows are a great thing until the flange tape bakes in three seasons of Pomona sun and lets go. We replace the flange with rated tape, verify the rough opening is still square, and reset the window so the exterior finish stays watertight.
Dvele Service in Pomona: What Local Conditions Mean for Your Equipment
Pomona sits at the eastern edge of LA County where the San Gabriel Valley meets the Inland Empire. The construction story here isn’t tract-home subdivisions; it’s older single-family housing stock and aging commercial buildings from the citrus and rail era being remodeled, added onto, and re-invested in. That’s the exact opposite of what Dvele’s factory-built panel system was designed around. A Dvele ADU placed on a Pomona lot usually has to integrate with a house built in the 1940s, 50s, or 60s, with all the foundation irregularities, lot-line issues, and unpermitted history that comes with it. The pre-1970s bungalows flanking downtown and near the colleges were built in a different era, before anyone imagined a factory-built module arriving on a truck. That means our crews spend as much time on pre-construction site work, permitting, and legalizing existing conditions as they do on the actual module set and finish.
Dvele Models & Products We Service in Pomona
We build, finish, and repair Dvele factory-built single-family modular homes, ADU and small-home modules, and prefab systems with integrated mechanical and electrical rough-in chases and pre-installed windows. For structural connectors, sealants, window components, and system gaskets, we specify factory-original or Dvele-spec equivalents so the tolerances hold. For finish materials, doors, and hardware, we source quality equivalents where the spec matches and the homeowner keeps money in pocket. On repairable set-seam or finish issues, we fix rather than replace. Replacement only makes sense when a module’s structural or weather-barrier integrity is actually compromised, and we’ll tell you straight which situation you’re in.

FAQs – Dvele Construction in Pomona
Yes, that’s one of the more common situations we handle in Pomona. Before any new modular structure can be permitted, our crew documents the existing unpermitted conversion, works through the legalization process with the City of Pomona, and then proceeds with the Dvele ADU set and finish. Call (855) 473-5620 and we’ll tell you exactly what the city is going to require for your specific property.
Because the panel-to-panel seams are moving with the thermal cycles, and the original finish wasn’t built to flex. Pomona’s inland heat and Santa Ana wind swings stress the seam constantly, just as they do for properties needing Los Serranos Dvele service. The fix is a proper flexible transition at the panel break, not another coat of patch. We open the seam, install the right tape and lath, and re-stucco so it moves without cracking. Call us and we’ll take a look at what’s happening on your walls.
We are not Dvele-authorized. We’re an independent service provider, so we don’t file warranty claims on Dvele’s behalf and we can’t tell you what their warranty department will decide. What we can do is diagnose the actual failure, repair it to factory spec, and give you documentation the manufacturer can review. If it’s a warranty case, you’ll have the evidence. If it isn’t, you’ll have the repair done right. Call (855) 473-5620 to schedule a diagnosis.
Yes. Pomona requires permits for modular and prefab additions just like any site-built structure, and the city will check for unpermitted work already on the property before issuing anything. We handle the permit package, the existing-condition documentation, and the inspection process from start to final sign-off, so you don’t have to walk through the city’s process alone.
Sometimes, and only within the limits of the factory’s design. The chases are built into the module, so relocation depends on the specific Dvele model, the chase layout, and what the site conditions require. We’ve done realignment work on Pomona ADUs where the chase needed to move to hit the foundation or the utility stub-out. Call (855) 473-5620 and we’ll tell you whether yours can move before you spend money on site work.
