Dvele Construction in Sunnyvale, CA | Ashford Contractors
We provide independent Dvele construction service across Sunnyvale, from the 1950s rancher tracts of 94087 to the newer infill lots in 94085, and we also offer General Contractor in Sunnyvale support for related site-built work. We are not a Dvele-authorized dealer, and we do not pretend to be. What we bring is years of hands-on work closing out Dvele shells, correcting transport racking, and running the seismic and Title 24 gauntlet that Sunnyvale’s building department puts every modular project through. That local approval work is where a prefab home either succeeds or stalls. If you own a Dvele home in Sunnyvale or are planning one, call us at (877) 752-3868 and we will tell you honestly what your project needs.
Why Sunnyvale Residents Choose Us for Dvele Service
Most remodelers in Sunnyvale know stick framing. A Dvele Origin Series or Summit Series panel is a different animal. Factory tolerances, marriage lines, factory-applied waterproofing, and module-to-foundation anchor spacing all behave differently than site-built walls, and the inspectors here know it. Glen Mossier grew up in Foster City’s Marlin Cove neighborhood watching lagoon-side homes get rebuilt after water damage, and he trained in construction technology at Skyline College in San Bruno before spending two decades on structural remodels across the Peninsula. That foundation informs how our crew approaches every Dvele project: read the factory engineering, compare it to Sunnyvale’s site-built shear wall requirements, and correct the gap before inspection. We also work across Dvele sales & service scopes beyond just repair, so we understand how the whole system should perform.

Common Dvele Construction Problems We Solve in Sunnyvale
Dvele homes are well engineered at the factory, but the trip from factory to foundation stresses panels in ways that show up months or years later. Here is what we see most often in Sunnyvale, and what local conditions do to each problem.
- Transport-induced micro-cracking at shear wall to foundation interfaces. The ride from factory to lot can hairline-crack the panel edges where shear walls meet the anchor bolts. Sunnyvale’s seismic bolting inspections catch these because inspectors compare factory calcs to the site-built shear wall spec. We repair the interface with equal-or-better aftermarket seismic hardware before it becomes a structural flag.
- Panel joint differential movement at roof-to-wall connections. Sunnyvale’s wet season runs concentrated from late fall through spring, and the first winter after a modular set is when marriage-line seal failures show up as roof leaks. The panels move slightly with temperature swings, and factory sealant does not always survive the first full cycle.
- Factory waterproofing compromised at plumbing penetrations during MEP rough-in. The factory applies waterproofing before plumbing is roughed in on site. When a plumber cuts through that membrane for a shower valve or tub drain, the seal is broken and slow leaks start behind tile. This is the most common Dvele bathroom failure we find in Sunnyvale remodels.
- HVAC chase misalignment between modules. When two modules meet, the factory-cut HVAC chases do not always line up. The resulting duct leakage fails Title 24 HERS verification, which Sunnyvale requires on nearly every project. We realign and seal the chases before testing.
- Foundation settlement gaps on slab-on-grade lots. Many older Sunnyvale lots in 94086 and 94087 were graded decades ago for single-story ranchers. A heavier two-module Dvele set can expose differential settlement, which opens panel joints and stresses roof connections. We level and shim, then reseal the marriage line.
Dvele Service in Sunnyvale: What Local Conditions Mean for Your Equipment
Here is the part you will not find in a generic Dvele guide. Sunnyvale’s building department requires separate seismic and Title 24 calculations for every modular addition or ADU. That is not a coastal-California generic requirement; it is a Sunnyvale-specific approval step. The plan reviewer compares Dvele’s factory engineering directly to the site-built shear wall calcs, and that comparison often surfaces anchor spacing discrepancies unique to prefab panel systems. On a Dvele Origin Series home in the 94087 ZIP near our Dvele repair in Loyola coverage area, our crew addressed a persistent roof leak where module panels met the site-built garage. We found the factory sealant had failed at the marriage line. After re-flashing and applying a Title 24-compliant membrane, we passed Sunnyvale’s inspection on the first try, and we documented the fix so the homeowner had a record for the next project. In older Sunnyvale tracts, where a single rancher on an oversized lot is now a permitted second-story addition or an ADU behind the main house, that documentation matters because inspectors scrutinize the seismic and energy calcs as closely as the framing itself. If you are planning a Dvele project in Sunnyvale, the approval path is the project. We have walked it enough times to know where it snags.
Dvele Models & Products We Service in Sunnyvale
We work on the full Dvele product range: the Origin Series, Vista Series, Summit Series, and Custom Modular builds. Our parts approach is straightforward. We source Dvele-specific connectors, sealants, and panel hardware from the factory when it is available and correct for the application. When it is not available or a factory part underperforms against Sunnyvale’s code requirements, we use equal-or-better aftermarket seismic hardware and waterproofing membranes. Compliance wins over brand loyalty every time. For most panelized Dvele issues, repair is the right call. Structural damage from transport racking or significant foundation movement may justify replacement, but we will show you the condition before we recommend spending that money.

FAQs – Dvele Construction in Sunnyvale
We can modify the layout in most cases, but the structural warranty picture depends on what you are changing. Interior partition moves away from panel joints rarely affect the factory structural warranty. Cutting into a shear wall or altering a marriage line does, and the right approach is usually to document the modification and submit it with your Sunnyvale permit package so the building department reviews it as part of the approval. That documentation protects you if a future structural question comes up. Call (877) 752-3868 and we will assess the specific walls you want to move.
We document the defect, photograph it, and file the information with Dvele’s warranty group on your behalf if the home is still under factory coverage. For defects outside the warranty window, we quote the repair using the same factory or aftermarket materials we would use on any Dvele panel system. Either way, you get the defect in writing before any repair starts, and we pull permits for the work if Sunnyvale requires them. For an exact repair quote, call (877) 752-3868.
Most Dvele kitchen remodels in Sunnyvale run six to ten weeks from the first demo day to final inspection. The variable is approval. If your project touches a panel joint or the Title 24 calcs change, the Sunnyvale plan review adds time. We sequence the permit work first so inspections do not stall the finish. Call (877) 752-3868 for a schedule estimate tied to your specific scope.
Yes, most roof repairs on a Dvele home in Sunnyvale need a building permit, especially if the repair involves a marriage line between modules or changes the roof assembly. Sunnyvale treats modular roof systems as engineered assemblies, so we pull the permit, adjust the Title 24 calcs if needed, and schedule the inspection. A simple patch on field shingles is sometimes exempt, but we will confirm with the city before touching anything. Call (877) 752-3868 with your roof’s condition and we will tell you what the permit path looks like.
Yes, but the approach is different from a site-built home. The factory waterproofing behind the existing shower often gets cut during demolition to expose plumbing. Before any tile goes back up, we re-waterproof the entire wet area with a Title 24-compliant membrane and tie it into the factory membrane at the panel joints. That continuity is what prevents slow leaks behind tile in a Dvele bathroom. Call (877) 752-3868 for a shower conversion quote in Sunnyvale.
