Why San Bernardino Residents Choose Us for Dvele Service

Our Dvele sales & service experience comes from working on these panelized, factory-built modular units throughout the Inland Empire. We understand factory tolerances and the site-built interfaces most contractors miss. We’re independent. No dealer network. No manufacturer pressure. We answer to you, the homeowner.

Neil Stratton leads our crew. He’s managed Dvele in Highland and around the region, so he knows the specific headaches San Bernardino throws at prefab installs: old single-panel electrical service, 1940s-era grading, and alleys that were never designed for a crane. That’s why we start every Dvele project in San Bernardino with a site assessment that checks what’s underground, overhead, and at the property line before money gets spent. From permit to punch-list, we keep the whole thing moving.

Common Dvele ADU Problems We Solve in San Bernardino

Here’s what we actually see on Dvele units in this city:

• Factory panel seams opening during transport. Dvele units ship panelized and get craned into place. On San Bernardino’s older streets, the ride to the lot plus the lift itself can pop a seam, especially on north-facing walls. We caught one on a 92405 install, re-flashed it, and sealed it before the first Santa Ana wind hit.
• HVAC undersizing on hot summer days. Dvele modular units ship with mechanicals specced for a generic California climate. San Bernardino routinely pushes past 100°F. Without recalculating for Inland Empire design-day temperatures, the mini-split struggles and the unit bakes. We check load sizing on every install we touch.
• Electrical service mismatches. Most homes here were built between the 1940s and 1970s with a single-panel service. Add a Dvele unit’s load and you’re over capacity. We flag this in the site assessment and get the panel upgraded before the unit arrives, not after it’s sitting there.
• Settling and joint separation from old lot grading. A lot graded before 1940 has soil and drainage conditions nobody re-checked. When a Dvele lands on a foundation poured to current spec but the surrounding yard still drains toward it, you get movement and gaping panel joints over time.
• Roof-to-wall flashing failures on mountain-adjacent lots. In 92407, Santa Ana wind-driven rain hits differently than in the flat valley. Flashing details that work fine in Fontana leak here because the wind drives water sideways into the transitions. We use materials rated for ember exposure and wind-driven moisture up there.

Dvele Service in San Bernardino: What Local Conditions Mean for Your Equipment

Most Dvele repair in Loma Linda and modular installs in San Bernardino land on 1940s-1970s lots in 92404 and 92405 with existing detached garages fronting alleys. That’s the thing that trips up a generic Dvele contractor. The crane and delivery path usually runs down that alley, not the street. So before Dvele ships, someone has to map alley access, overhead lines, and garage roof clearance. Miss that, and you’ve got a crane sitting on a residential street with nowhere to swing. We re-survey these things before the delivery window. A family on a wide side-yard lot in 92405 had us set a Dvele Sol series modular unit at the rear. Their crane access ran down the alley behind the detached garage. We caught a panel joint on the north wall after set and re-flashed and sealed it against the Santa Ana wind-driven rain. We also upgraded the aging single-panel electrical service to carry the Dvele load before final inspection. That’s the difference between a San Bernardino install that holds up and one that becomes a six-month punch-list headache.

Dvele Models & Products We Service in San Bernardino

We service the full Dvele line: the Sol series modular ADU, the Haven series prefab ADU, custom panelized detached ADUs, and two-story modular ADUs. For parts, we source Dvele-spec factory replacement panels and proprietary connectors directly from the manufacturer when they’re available. Where the factory part isn’t the right call, we use equivalent structural and MEP components rather than forcing an OEM piece into an interface it wasn’t designed for. That’s a repair-versus-replace judgment we make honestly. If a Dvele shell is sound but the mechanicals are failing, we repair. If foundation or module-level structural problems show up, we’ll tell you when replacement is the better spend.
