Dvele Construction in San Martin, CA | Toolbox Contractors

We’re an independent construction crew that works on Dvele panelized and modular homes across San Martin and the surrounding Santa Clara County ranch country. We handle everything from the site prep and county permitting to the envelope detailing and interior finishes around Dvele’s factory-built shells. If you own a Dvele home here, or you’re planning to put one on a San Martin parcel, we already know what the county will flag before the modules ever leave the factory. Call (855) 382-3257 to talk through your project.

The short version: we’re not a Dvele dealer and we don’t work for the factory. We’re the crew that makes their homes actually work on the ground in San Martin, where the clay moves, the county inspects, and the fire marshal wants details a generic drawing never showed.

Why San Martin Residents Choose Us for Dvele Service

Norm Castellano grew up around houses that were always half-finished, and he’s spent two decades untangling projects other contractors walked away from. That’s exactly the skillset a Dvele build in San Martin calls for. The factory delivers a tight, well-engineered shell. The site conditions here, the unincorporated county rules, the buried orchard infrastructure, they’re all site-built problems that don’t show up in the Dvele manual. We bridge that gap.

We know how Dvele’s panel joints and marriage lines behave when they land on expansive former-orchard clay. We know what Santa Clara County wants to see before it signs off on a modular set. And we know which parts of a Dvele envelope will need local detailing, fire-rated venting, positive drainage, and septic coordination, long before the crane shows up. You’re not hiring a factory rep. You’re hiring a General Contractor in San Martin who already understands both halves of the job.

We also offer full-scope remodeling through one contract. Same crew that handles your Dvele shell can gut and rebuild the kitchen with KraftMaid cabinets and Caesarstone counters, replace the roof with a GAF system, and rework the bathrooms with Kohler or Moen fixtures. One point of accountability from the modules to the finishes.

Common Dvele Construction Problems We Solve in San Martin

• Module marriage-line and panel-joint separation from expansive clay. San Martin sits on former orchard ground, and when that clay gets wet in winter then bakes dry in summer, it moves. If the pad wasn’t over-excavated and moisture-conditioned before the modules were set, the seams between factory sections start to open. The shell is fine. The ground under it isn’t. We correct the drainage and re-flash the joints, and we only recommend panel rework when movement has actually distorted the modules.
• Roof-edge and eave terminations that pack with grit and embers. San Martin’s wildland-urban interface rules mean a factory-sealed Dvele envelope needs site-built fire details the original drawings often don’t spell out for high-severity zones. We hard-end roof edges and replace vulnerable vents with ember-resistant assemblies that actually pass a county WUI inspection.
• Roof-to-wall flashing and drainage failures after winter rains. If site grading against the modules was never tied to a positive-drainage plan, water runs under the shell and eats at the connection hardware. We regrade, install proper swales, and rework the flashing so the water goes somewhere besides into the envelope.
• Mismatched utility penetrations on raw ranch parcels. Standard Dvele factory layouts assume a clean lot. San Martin parcels hide buried irrigation lines, old well casings, and septic systems the seller maybe didn’t disclose. We scope the parcel before the modules arrive so the factory penetrations match the site reality, not the other way around.
• Interior finish work left to a second crew. The Dvele package gets you a shell. The kitchen, baths, and flooring are site-scope. We handle those from start to finish with the same contract, using brand-name materials from our 50+ vetted manufacturers, so you’re not coordinating a shell contractor and a finish contractor on a county-permitted job.

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

Here’s the thing about San Martin most people don’t get until they’re already in the permit process. The whole area is unincorporated. That means your Dvele build is permitted and inspected by Santa Clara County, not a city building department, and the county’s reviewers look at these parcels differently than a Morgan Hill or Gilroy city plan checker ever would. They know the orchards. They know the clay. They know the old irrigation lines that crisscross these lots. And they want documentation showing the pad was engineered for expansive soil before any modules get set.

We’ve worked parcels off the Llagas-area ranch roads where site prep turned up exactly that, buried irrigation lines and a capped well casing the seller never disclosed. On one one-acre former-orchard parcel in 95046, we were setting a Dvele modular home for a family replacing an aging single-story ranch, and the excavation caught old orchard plumbing nobody had on a map. We re-routed utilities, over-excavated and re-compacted the clay pad before the crane set the modules, and hard-ended the roof-edge venting to the county’s WUI fire details. Two winters later the marriage lines are still tight and the drainage swales are moving water away from the foundation as intended. That’s not luck. That’s knowing what this ground does before you build on it.

Dvele Models & Products We Service in San Martin

We work on the full Dvele lineup as site and envelope contractors, not factory techs. That includes Dvele’s fully modular single-family home packages, the panelized enclosure and roof-panel systems used on custom ranch-lot builds, their high-performance sealed envelope assemblies, and the modular ADU and accessory-structure packages. Where a module or panel joint depends on Dvele’s factory components and connection hardware, we match them. Where the site condition governs, ember-resistant vents, Class A roofing material, positive-drainage flashing, we use the right aftermarket part and document it for the county.

We repair module-level and envelope issues honestly when the shell is sound. We only recommend re-working major assemblies when drainage or foundation movement has actually distorted the panels. And we stock the common connection hardware, flashing profiles, and fire-rated vent components locally so a San Martin service visit doesn’t wait on a factory shipment.

Our Dvele sales & service work always starts with the site, not the shell. That’s what keeps these homes tight here.

FAQs – Dvele Construction in San Martin

Do I pull my Dvele permit through Santa Clara County or a city for a San Martin address?

Santa Clara County, every time. San Martin is unincorporated, so there is no city building department in the loop. The county handles building, fire, grading, and often the well/septic sign-offs on the same plan check. If you’re in 95046, budget for county review timelines and WUI submittals from day one.

Why does my Dvele home show cracks at the module seams even though the panels look fine?

That is almost always expansive clay under the pad, not a factory defect. San Martin’s former orchard soils shrink and swell enough to move a set module over two or three wet-dry cycles. The fix starts with drainage and pad correction, then re-flashing the marriage lines. If you catch it before the panels distort, you usually don’t need to re-work the shell. Call (855) 382-3257 and we will tell you what you’ve actually got.

What fire-hardening does a Dvele build in San Martin’s wildland-urban interface actually need?

Class A roofing, ember-resistant vents, hard-ended roof edges, and defensible-space grading that the county fire marshal can sign off on. The factory envelope often needs site-built detailing at the eaves and penetrations to meet the WUI checklist. We handle that as part of the same contract.

Can we add a kitchen or bathroom remodel without re-engineering the Dvele shell?

In most cases, yes. The Dvele structure is independent of the interior finishes, so gutting a kitchen or bath doesn’t touch the factory engineering. We do full kitchen remodels with KraftMaid or Wellborn cabinets and Caesarstone or Silestone counters, and full bath remodels with Kohler, Moen, or Grohe fixtures. The shell stays intact. The county cares about plumbing and electrical scope, which we pull and pass.

What should we check before a Dvele ADU or addition goes on a San Martin ranch parcel?

Utility locations, soil bearing, and fire setbacks. Old orchard parcels in San Martin hide irrigation lines, capped wells, and clay that hasn’t been tested since the trees came out. We scope the site before the Dvele package is ordered so the factory layout fits the parcel. Call (855) 382-3257 for a free site walk.
