Dvele Construction in San Martin, CA | Gold Star Contractors
We’re Gold Star Contractors, an independent General Contractor in San Martin and a Dvele service provider working across the area. We build, repair, and retrofit Dvele panelized homes, and we’re not authorized by Dvele, which means we answer to one party only: you. The thing that separates our Dvele work in San Martin from everywhere else is simple – this is unincorporated Santa Clara County, so every Dvele panel we set has to clear county-level septic and well review before concrete ever hits the ground. Call (833) 382-8544 for a free estimate from a team that understands Dvele assemblies on rural land.
Why San Martin Residents Choose Us for Dvele Service
Dvele homes go together differently than stick-built houses. The factory-panelized shell system has specific tolerances, joint details, and weather-proofing requirements. Most general contractors in Santa Clara County have never touched one. We have. Noel Carranza grew up watching older tract homes get renovated block by block in Anaheim’s Platinum Triangle, and that early exposure to how buildings actually go together stuck with him. He studied construction technology at Fullerton College and spent his twenties doing concrete work and finish carpentry before building Gold Star Contractors. Now we bring that hands-on, multi-trade background to every Dvele project in San Martin, from ADU construction to full panel retrofits on existing Dvele homes.
One contractor. Every system. No handoff gaps. When a Dvele panel joint fails or a roof cassette needs fire-code retrofit, you’re not juggling a framer, a roofer, and a county inspector. We coordinate the whole scope, including the county paperwork most city contractors don’t know exists in San Martin.

Common Dvele Construction Problems We Solve in San Martin
- Panel joint sealant failure at wall-to-roof intersections. San Martin’s hot, dry summers bake west-facing walls, and the dust that blows across graded rural lots grinds into sealant beads. We see joints on west exposures fail years earlier than east-facing ones. We remove the failed sealant, prep the joint, and re-seal with material rated for high-UV, high-dust conditions.
- Factory roof cassette flashing that doesn’t meet Class A fire requirements. Parts of San Martin sit in wildland-urban interface zones, and not every Dvele roof cassette ships with Class A-compliant flashing from the factory. We retrofit the flashing so the assembly passes Santa Clara County fire review.
- Foundation settling on former agricultural soil. Much of San Martin’s buildable land was orchard or row-crop ground. That soil compacts unevenly, and Dvele’s panelized walls telegraph even minor settling as door and window misalignment. We over-excavate, re-compact, and set panels on properly engineered foundations.
- Poorly sealed utility penetrations. Rural San Martin means orchards, fields, and rodents. Mice and rats find their way through plumbing and electrical penetrations that were sealed hastily at the factory or on-site. We seal every penetration with pest-resistant materials and verify before close-up.
- Panel racking from expansive clay. Some San Martin parcels have clay soil that swells and shrinks with moisture. That movement racks Dvele panels if the slab wasn’t designed for it. We assess the soil, the slab, and the panel connections, then correct the cause rather than chasing the symptom.
Dvele Service in San Martin: What Local Conditions Mean for Your Equipment
Here’s what separates Dvele construction in San Martin from the same job in Morgan Hill or Gilroy. San Martin is unincorporated. That means every Dvele addition, ADU, or new build clears Santa Clara County Building and Safety, not a city building department. And because most San Martin lots are on private wells and septic systems, the county routinely requires a percolation test and well setback verification before any panel foundation is poured. That gating step doesn’t exist on city-sewer lots in Morgan Hill. It adds weeks to the front end of a project, and it’s exactly the kind of thing a contractor who only works incorporated areas never anticipates. We recently set a Dvele LUMEN Series ADU on an acre-and-a-half parcel off Maple Avenue. The county required septic clearance before we could pour the slab. We coordinated the perc test and well setback review, over-excavated a former orchard pad to reach stable soil, then set the panels. Final inspection passed with no joint issues, and the owner now has a code-compliant rental unit. That’s the San Martin difference, and it’s why you want a contractor who already knows the county’s playbook. Our full Dvele sales & service team brings that county-level experience to every project.
Dvele Models & Products We Service in San Martin
We work on the three production Dvele lines: the LUMEN Series, the ONE Series, and the Custom Line. Each has different panel sizes, joint details, and roof cassette configurations, but they share the same factory-panelized DNA. When a structural panel or envelope component fails, we use Dvele OEM parts to preserve system integrity. For non-structural finishes like sealants, trim, and flashing, we source high-quality aftermarket equivalents that meet or beat factory specs. We keep common sealants, flashing profiles, and fasteners stocked locally so San Martin service calls don’t wait on cross-country shipping. Repair-versus-replace calls are made case by case: we repair localized issues, and we only replace a full panel when the structural bond or weather seal is compromised beyond repair. If you’re considering a Dvele build, speak with our San Martin service area team about what fits your lot.

AfterDvele Service Pricing in San Martin
Dvele work in San Martin carries a wider cost range than the same work on a tight subdivision lot. County permits, septic and well reviews, agricultural grading questions, and rural site access all shape the final number. Here are the ranges we typically see:

|---|---|
| ADU Construction | $90,000 – $220,000 |
| Home Addition | $45,000 – $130,000 |
| Roof Replacement | $8,000 – $20,000 |
What drives the cost: soil conditions on former agricultural land, whether the county requires a perc test and well setback review before foundation work, fire-code retrofit needs on roof cassettes, and the condition of any existing panel joints. Our free estimate includes a written line-item breakdown, so you know what’s permit, what’s labor, and what’s material. Call (833) 382-8544 for a fixed quote on your Dvele project in San Martin.

FAQs – Dvele Construction in San Martin
Yes. San Martin is unincorporated, so Dvele ADUs clear Santa Clara County Building and Safety, not the city of Morgan Hill or Gilroy. Because most San Martin lots are on private wells and septic, the county typically requires a percolation test and well setback verification before a panel foundation is poured. That step doesn’t exist on city-sewer lots in neighboring cities, and it adds weeks to the front end. Call (833) 382-8544 if you want our team to handle the county path from day one.
Former orchard and row-crop soils in San Martin tend to compact unevenly and may contain pockets of loose fill or decomposing root material. Dvele’s panelized walls transfer any slab settling directly into door and window misalignment, and in some areas expansive clay causes panel racking. We over-excavate to stable soil, re-compact, and engineer the slab for the specific soil we’re on. The answer depends on your parcel. Call (833) 382-8544 for a site-specific foundation assessment.
West-facing panel joints take the worst of it. San Martin summers push temperatures high enough to accelerate UV breakdown of sealant, and dust from graded rural lots acts as an abrasive, grinding into joint material every time the wind picks up. We see sealant failures on west exposures five to ten years earlier than on shaded walls. We re-seal with products formulated for high-UV, high-dust environments, and we verify joint adhesion before close-up.
Some factory Dvele roof cassettes ship without Class A-compliant flashing, and parts of San Martin fall within wildland-urban interface zones. If Santa Clara County fire review flags a cassette, we retrofit the flashing to meet the code before final inspection. If you’re planning a Dvele build or addition in San Martin, have us review the roof assembly during the estimate so you’re not surprised late in the project. Call (833) 382-8544 for a free roof assembly review.
Yes. San Martin has a lot of older ranch-style homes on acre-plus lots, and tying a Dvele panelized addition into one is a different animal than building a standalone ADU. The connections at the roof line, the foundation transition from existing slab or pier construction, and the utility tie-ins all need careful detailing. We’ve done it, and we handle the county permits, the septic and well clearance, and the structural connection as one scope. Call (833) 382-8544 to talk through your addition.
