Dvele Construction in Tustin, CA | Square One Builders
We provide Dvele sales & service across Tustin, from panelized additions in Old Town to full self-powered homes out at Tustin Legacy. We’re not a Dvele dealer or factory affiliate – we’re a general contractor who sets, finishes, and repairs Dvele panelized and modular structures, and we work for the homeowner, not the manufacturer. What makes our Dvele work different in Tustin is that we understand the city’s unusual split between pier-and-beam bungalows and slab-on-grade infill, and we detail every panel seam and tie-down to match the lot you actually own. Call (877) 688-9930 for a free estimate on any Dvele project.

Why Tustin Residents Choose Us for Dvele Service
Dvele structures are precision-built in a factory, but they land on Tustin soil – and that’s where the real work happens. We’ve set and finished Dvele wall, floor, and roof panel assemblies across Southern California, and we know how those assemblies behave when they meet a 1920s Craftsman on raised piers or a 2000s stucco tract wall on slab-on-grade. Brent Calloway, our owner and general contractor, grew up in Midway City and spent three decades working Orange County homes before leading Square One Builders. His grandfather was a carpenter who never wasted a board, and that same instinct against wasted material, wasted time, and wasted opportunity drives how we scope every Dvele job. We use Dvele-specified panel connectors where the structural assembly demands them, and quality aftermarket cladding and sealants where they outperform the factory part. One contractor, every system – from the panelized shell down to the flashing and finish.

Common Dvele Construction Problems We Solve in Tustin
- Panel-to-foundation seam movement on Old Town pier-and-beam retrofits. When a Dvele panelized addition meets a 1920s-40s raised bungalow in 92780, the existing house has usually settled on its own schedule. The panel seam opens, the flashing pulls, and water finds its way in during winter rains. We re-underpin or shim the piers first, then close the seam so it drains cleanly instead of fighting the movement.
- Ember and UV intrusion at panel penetrations on Tustin Legacy and hillside-adjacent parcels. Santa Ana wind events push embers hard against roof edges and wall penetrations in 92782. Factory-sealed Dvele penetrations that were fine on paper can dry out and crack after a few seasons of Tustin sun and wind. We re-flash and re-seal with materials that hold up to UV and ember exposure.
- Stucco and cladding joint cracking where Dvele panels tie into 1980s-2000s Tustin Ranch tract walls. Slab-on-grade tract homes move differently than panelized assemblies, especially at attached-garage corners. The joint cracks, water gets behind the cladding, and the damage compounds. We re-detail those tie-ins before they become a structural problem.
- Crane-set and finish-out defects from panels delivered to unverified sites. Racked openings, out-of-plumb walls, and door or window reveal gaps happen when panels are set on ground that wasn’t checked for level before the truck arrived. We fix that: we verify, shim, and square every panel before finish work begins. If an opening is too far out to re-detail, we’ll tell you the panel section should be replaced. We won’t hide behind trim.
- Panel seam leaks that factory touch-up caulk can’t fix. Dvele panel seams are precise when they leave the factory, but Tustin’s fall Santa Ana winds and winter rain cycles stress them hard. We remove failed factory sealant, inspect the panel edges, and re-detail the seam with flashing and sealants that move with the assembly.
Dvele Service in Tustin: What Local Conditions Mean for Your Equipment
Tustin is one of the only Orange County cities where a Dvele set crew can be tying panels into a 1920s pier-and-beam bungalow in Old Town 92780 one week and setting modules on fresh slab-on-grade infill out at Dvele in North Tustin the next. Two completely different foundation and tie-down playbooks inside the same permit jurisdiction. The old military blimp hangars at the former MCAS Tustin – among the largest wooden structures ever built – are a local touchstone for anyone who understands how wood assemblies behave over time. A Dvele panel tied to a raised pier foundation near El Camino Real needs vertical movement accommodation at every seam. A Dvele module set on slab at Tustin Legacy needs lateral tie-down and seismic anchoring appropriate for new infill construction. We check the actual foundation condition before we ever set a panel, because the wrong playbook on a Dvele addition is an expensive lesson. We saw this play out on a raised pier-and-beam Craftsman in Old Town near El Camino Real: the existing rear wall had settled nearly an inch out of level, so we re-underpinned the piers and shimmed the panel-to-foundation connection before closing the seam. That tie-in now flashes and drains cleanly through the fall Santa Ana winds. Start from square one, build it right.
Dvele Models & Products We Service in Tustin
We work on the full Dvele range: the Dvele Self-Powered Home with its solar-plus-battery package, custom modular single-family shells with panelized wall and roof assemblies, Dvele ADU and accessory dwelling module packages, and Dvele panelized room-addition and infill packages. When a structural connection depends on Dvele-specified panel connectors or fasteners, we use them. When cladding, flashing, or sealants need to outperform the factory part – which is often the case in Tustin’s sun, wind, and rain cycles – we spec aftermarket materials that do the job better. We keep standard Dvele-compatible connectors and flashing on hand for faster turnaround on Tustin jobs, and we’re honest about when a seam can be re-detailed versus when a panel section should come out. No mystery. No factory jargon.

AfterDvele Service Pricing in Tustin
Dvele work in Tustin costs what it costs because of the scope, not because we pad the number. A panelized room addition runs a wide range depending on site prep, foundation work, and whether we’re tying into a settled Old Town bungalow or setting on clean Tustin Legacy slab. A Dvele ADU package lands differently on a Tustin Ranch tract lot with an attached garage than on an open Legacy parcel. Here’s what to expect:
| Service | Typical Tustin Range |
|---|---|
| Home Addition | $45,000 – $130,000 |
| ADU Construction | $90,000 – $220,000 |
| Full Kitchen Remodeling | $14,000 – $45,000 |
| Roof Repair | $400 – $1,800 |

FAQs – Dvele Construction in Tustin
Yes, and we do it regularly in 92780. The work requires assessing the existing pier condition, re-underpinning or shimming where the old house has settled, and detailing the panel-to-foundation connection so it moves with the structure instead of against it. Get a free assessment – call (877) 688-9930.
Yes. Tustin Legacy 92782 is mostly fresh slab-on-grade infill, which means lateral tie-down and seismic anchoring are the priority. Old Town’s raised piers need vertical movement accommodation at every seam. Different foundation, different playbook. We’ll tell you which one your lot needs.
Dvele repair in Santa Ana becomes critical when winds in fall push embers and fine dust hard against Dvele panel seams, roof edges, and penetrations. Factory sealant dries out under UV and fails under wind pressure. We re-flash and re-seal with materials rated for ember and UV exposure, so your Dvele envelope holds through the wind season. Call (877) 688-9930 for an inspection.
Yes. Tustin Ranch 92782 lots with attached garages usually have slab-on-grade construction, which simplifies the Irvine Dvele service ADU tie-in. The work involves verifying the existing slab condition, detailing the module-to-slab connection, and re-working any stucco or cladding joints where the new structure meets the garage wall. We scope and build it from the ground up under one contract.
Full kitchen remodeling in Tustin runs $14,000 to $45,000 depending on the existing structure, cabinet and countertop selections, and whether we’re integrating Dvele panelized components.
