Dvele Construction in Midway City, CA | Square One Builders
We’re Square One Builders, an independent General Contractor in Midway City with Dvele panelized construction, additions, ADUs, and garage conversions. We are not authorized, endorsed, or affiliated with Dvele – we’re the crew that actually sets the panels, chases the seams, and makes the envelope right. The thing that makes Dvele work different here: Midway City is unincorporated, so every Dvele project runs through Orange County plan check, and most of these tight post-war lots leave no room for error (or staging). Call (877) 688-9930 to talk through your lot.

Why Midway City Residents Choose Us for Dvele Service
We’ve spent years pulling apart and reassembling Dvele’s panelized shell, seam, and roof-edge assemblies on tight Orange County infill lots, so we know where the system’s tolerances actually bind. Brent Calloway, our owner, grew up in the Midway City pocket just off Bolsa Avenue and has spent the better part of three decades working on homes throughout Westminster and the surrounding communities, where our Westminster Dvele service has earned trust. He learned framing, concrete, and finish work through the Construction Technology program at Golden West College, then spent years doing the ground-level work – hauling material, reading blueprints in parking lots, asking questions until he got straight answers. That’s the standard we bring to every Dvele job in Midway City. We work on the envelope and finish side, not as factory reps.

Common Dvele Construction Problems We Solve in Midway City
- Panel-to-foundation seam movement on older slabs. Dvele shells are precise. A 1950s Midway City slab is not. When a panelized room addition or ADU gets set on a post-war tract slab that’s out of level, the panel-to-foundation connection shifts and the seams open up. We straighten the connection, shim correctly, and close the gaps.
- Roof-edge and cladding flashing failures at panel joints. Santa Ana winds don’t treat Dvele joints gently. Edge uplift and sealant cracking at roof-to-wall transitions are the most common call we get in Midway City – it reads as a slow leak, not a sudden one. We re-flash the joint to Dvele’s weather barrier spec and move on.
- Solar and battery penetration moisture tracking. Dvele’s self-powered package means roof penetrations for conduit and mounting hardware. If those weren’t flashed to the panel’s weather barrier, marine-layer mornings in Midway City push moisture in along the seam. We strip, re-flash, and seal.
- Crane-set panel alignment issues on narrow lots. Streets off Beach Boulevard and Bolsa Avenue don’t give a crane much room. When panels get set a few degrees off square, interior seams gap and finish-out fails. We correct alignment before the drywall goes up.
- Detached garage and cottage shell tie-in problems. Many Midway City homes have detached garages and cottage-style shells built before current code. Tying a Dvele addition onto that framing takes careful load-path work and a lot of as-built documentation for the county.
Dvele Service in Midway City: What Local Conditions Mean for Your Equipment
Here’s what you won’t read on any other Dvele page: Midway City is unincorporated, so a Dvele addition, ADU, or garage conversion here is permitted and inspected through Orange County rather than a city building department. That sounds like a paperwork detail, but it changes how the project gets built. County plan check wants the existing structure documented before it will approve tying a new Dvele panel assembly onto a mid-century cottage shell. On a job off Bolsa Avenue, we had to submit as-built photos of the existing 1950s framing before the county would even review the addition drawings. The reason this matters for a Dvele shell specifically: the county reviewer treats the panel-to-house connection as a structural splice, not a fresh build, so the existing slab, foundation, and framing all go under scrutiny. In a city with its own building department, the review is often lighter. In Midway City, you need a contractor who has already been through that county process with panelized construction. We have.
Dvele Models & Products We Service in Midway City
We work on the full Dvele range: the self-powered single-family panelized home with integrated solar and battery, modular and prefab ADU packages, panelized room-addition and expansion kits tied to an existing home, and high-performance envelope builds spec’d for fire-hardened and WUI detailing. We match Dvele’s specified envelope components and flashing where the factory spec matters for weather- and fire-resistance. Where it doesn’t compromise the assembly – hardware, sealants, minor trim – we use quality aftermarket parts that hold up in Midway City’s coastal-influenced climate.

FAQs – Dvele Construction in Midway City
Does adding a Dvele panel addition in Midway City go through the county or a city building department?
Orange County. Midway City is unincorporated, so there is no city building department. Plan check, permits, and inspections all run through OC Public Works or the county’s building division, depending on the project type. We handle that end-to-end.
Can you set Dvele panels on my older Midway City slab instead of pouring a new foundation?
Sometimes. If your existing slab is within tolerance and the county accepts the structural evaluation, we can tie a Dvele panel assembly onto it. If it’s too far out of level, we’ll tell you straight – and a new foundation may be the better call. Call (877) 688-9930 and we’ll look at it.
How do you handle Dvele panel staging on a tight lot off Beach or Bolsa Boulevard?
Carefully, and usually with a crane set from the street. Those lots leave almost no side-yard room for staging, so panels get delivered the day of the set, not days ahead. We’ve done enough of these to plan the sequence before the truck arrives.
Do Dvele’s solar and battery penetrations hold up to Midway City’s marine-layer mornings?
They hold up when they’re flashed correctly. The failures we see are almost always installation-based – penetrations that were never sealed to the panel’s weather barrier, so marine moisture tracks in along the seam. We re-flash them to spec.
Is a Dvele garage conversion or ADU realistic on a small Midway City lot?
Usually yes. The lot coverage and setback rules in this area are tight, but a detached garage conversion or a compact Dvele ADU package fits more Midway City parcels than people expect. The limiting factor is usually the existing slab, not the lot size. Call (877) 688-9930 for an exact take on your parcel.
