Dvele’s prefab modular systems, including the Dvele ONE, Dvele TWO, and Dvele Accessory Dwelling Unit lines, arrive in Sunnyvale with factory-precision framing and integrated MEP chases that can save weeks on the construction calendar. But factory precision does not eliminate site-specific problems. The expansive Bay clay beneath Sunnyvale shrinks in dry months and heaves when winter rains return, which means foundation movement and module settlement are realities we plan for, not surprises we discover. Our crew has reworked Dvele installations where out-of-level piers caused spline binding at module seams, and we’ve corrected roof-to-wall flashing details that the factory spec did not account for in local wind-driven rain conditions. We know what Dvele homes do well and where they need a Sunnyvale-experienced hand.

Grant Rowan, our owner, grew up in Beverly Hills and picked up his first framing hammer before he could drive. He trained in construction technology at Santa Monica College, where coursework covered structural load calculations, blueprint reading, and site safety - fundamentals he still references when scoping a Dvele job today. For more than two decades he and our crew have worked across Sunnyvale, including extensive remodel and build-out work in Lakewood Village near Washington Park. “Measure it twice, write it down, then build it” - that’s the discipline we bring to every Dvele project.

Why Trust Rowan Construction Group Sunnyvale for Your Dvele Construction?

Our technicians are background-checked, uniformed, and trained specifically on Dvele’s modular connection systems, not general carpentry adapted on the fly. We carry OEM Dvele structural hardware and connection components for module-to-module repairs, and we stock locally manufactured, code-compliant alternatives for finishes, MEP fittings, and weatherproofing when OEM parts are back-ordered. Every visit includes a documented photo record as standard - not an upgrade - so you have evidence of what we found and what we corrected.

Under Clause 1 of the Haven Standard, the price is written before anyone starts. For Dvele work, that means a line-item estimate: material costs, labor hours, subcontractor scope for electrical or plumbing tie-ins, and any foundation remediation listed separately. No change proceeds without a signed change order. This is the administrative discipline that has kept our projects within a few percent of the agreed cost across 4,000-plus jobs since 2007.

We also offer a Free Second Opinion on any written estimate. Bring us a competitor’s Dvele quote and we will review it line by line at no charge. Our sourcing depth across fifty-plus vetted brands - KraftMaid and Wellborn cabinets, Cambria and Caesarstone countertops, GAF and Owens Corning roofing, Kohler and Toto fixtures - means the written quote contains honest numbers rather than inflated placeholders.

The 365-Day Done Right Promise applies to all Dvele work: if it is not done right, we make it right. The guarantee is printed on every page and backed by a terms page, not an asterisk.

Common Dvele Construction Problems We Fix in Sunnyvale

• Settlement at module-to-module connection seams. The Dvele ONE and Dvele TWO are delivered in sections, and the spline connections between modules bear directly on the foundation system. In Sunnyvale, the post-tensioned slabs common in 1970s and 1980s homes, or the pier-and-grade-beam foundations we specify on new construction in expansive clay soils, can shift seasonally. When piers settle unevenly, the factory spline binds, producing hairline drywall cracks along ceiling lines and air infiltration that shows up on blower-door tests. We open the seam, re-shim bearing points, and re-tape with flexible joint compound rated for structural movement.
• Water intrusion at factory-installed window and door penetrations. Dvele units ship with windows and doors pre-installed, which eliminates field flashing variability but also means the penetrations endure transport vibration and crane-setting stress. In Sunnyvale’s wind-driven rain, especially during winter storms off the Bay, the factory sealant bead can separate from the modular wall panel. We remove compromised sealant, install backer rod and fluid-applied membrane compatible with Dvele’s exterior cladding, and verify with a hose test before we leave.
• MEP rough-in misalignments between modules. The integrated MEP chases in Dvele homes are precise in the factory but can shift during transport or sit slightly out of plumb after setting. In a recent Dvele ADU installation near Birdland, the electrical conduit chase between the kitchen module and the bathroom module was offset by 3/4 inch, which prevented the GFCI circuit from grounding properly. We mapped the chase with a borescope, fabricated a custom offset coupling, and brought the circuit up to Sunnyvale’s current NEC adoption without opening finished walls.
• Roof-to-wall flashing details inadequate for local conditions. Dvele’s modular roof panels use a compression gasket at the wall transition that performs adequately in moderate climates. Sunnyvale’s combination of dry-season thermal expansion and winter wind-driven rain exceeds that gasket’s design range. We’ve replaced the factory detail with a stepped counter-flashing and self-adhered ice-and-water shield that meets CalGreen Tier 1 requirements and passes the Title 24 energy compliance report that Sunnyvale Building Division requires for any roof work.
• Exterior door threshold misalignment after module setting. The crane operator’s final placement determines whether the Dvele’s pre-hung entry door sits level. A threshold even 1/8 inch out of plane creates a capillary path for water tracking toward the wall base, which is how we find rot in the subfloor at six-month inspections. We relevel with composite shims, seal the threshold pan to the sill plate, and verify with a water flood test.

Dvele Parts & Our Repair-vs-Replace Approach

Because Dvele homes are engineered as integrated systems, we lean toward targeted repair and reinforcement rather than piecemeal replacement unless damage is extensive. We use OEM Dvele structural hardware and connection components wherever available to maintain module integrity. For finishes, MEP fittings, and weatherproofing, we source locally manufactured, code-compliant alternatives when OEM parts are unavailable - Cambria for countertop replacements where Dvele’s spec slab is discontinued, Kohler fixtures for bathroom repairs, GAF or Owens Corning roofing when the modular roof panel needs sectional replacement.

Our repair-vs-replace decision follows the documented photo record. We show you the crack pattern, the moisture meter reading, or the borescope image, then explain whether a local repair will last or whether the module connection needs full disassembly. No work proceeds until you have a written price and a signed scope. Call (650) 405-3637 for an exact quote - estimates are free.

Our Dvele Service Process - Step by Step

1. 1
   Diagnosis with documentation. We arrive with a blower-door kit, moisture meter, borescope, and level. For module seam complaints, we map the crack pattern and measure differential settlement across the foundation. For water intrusion, we trace the leak path with thermal imaging. You receive the photo record before we leave.
2. 2
   Written price, signed scope. Under Clause 1 of the Haven Standard, we deliver a flat written price with material costs, labor hours, and any subcontractor scope listed separately. On Dvele jobs, this includes OEM part numbers where applicable and local-equivalent alternatives where not.
3. 3
   Repair or installation with module-specific protocols. For module seam work, we support adjacent sections with temporary shoring before releasing the spline. For roof repairs, we coordinate with Sunnyvale Building Division for the required Title 24 energy compliance report. For ADU additions, we verify that the Dvele unit’s pre-approved plan matches Sunnyvale’s ADU program requirements before the crane arrives.
4. 4
   Testing and verification. We re-run the blower-door test after seam repairs, hose-test window penetrations, and flood-test door thresholds. The documented photo record from this step shows the correction and the verification.
5. 5
   Warranty documentation. The 365-Day Done Right Promise is printed on your invoice. The terms page is available on request. Our workmanship warranty runs concurrent with any remaining Dvele factory warranty, and we note where our work ends and factory coverage begins so there is no gap.

Dvele Products We Service & Install in Sunnyvale

We work on the full Dvele residential line: the Dvele ONE modular single-family home, the Dvele TWO modular single-family home, and the Dvele Accessory Dwelling Unit prefab offerings. We also handle Dvele custom modular home packages where the owner has modified the standard plan. For Sunnyvale’s teardown-rebuild market, we coordinate Dvele in Mountain View and local Dvele TWO installations on cleared lots in Birdland and Lakewood Village, including foundation design for expansive clay conditions. For the parallel ADU market driven by Sunnyvale’s pre-approved ADU plan program, we verify Dvele ADU compliance with local RHNA mandates and CalGreen Tier 1 requirements before permit submission. We stock OEM connection hardware, compatible sealants and membranes, and replacement thresholds and flashing kits for same-week turnaround on most service calls.

We Also Service These Brands

Our multi-brand capability means a Dvele kitchen repair can include KraftMaid cabinet adjustments and our Kitchen Remodeling services, a Dvele bathroom fix can specify Kohler valve compatibility, and a Dvele countertop replacement can quote Cambria or Silestone alongside the factory spec. We are not dependent on any single brand’s parts pipeline, which keeps your project on calendar when one supplier is back-ordered.

FAQs - Dvele Construction Service in Sunnyvale

Can you modify a Dvele modular home after it’s set, like adding a room or changing the roofline?

Yes, with engineering review. Dvele modules are structurally interdependent, so a room addition requires analysis of load transfer at existing module connections. We work with a structural engineer to design the tie-in, pull the required Sunnyvale permits with Title 24 compliance, and execute the modification without compromising the original module integrity. Call (650) 405-3637 to discuss your specific plan.

Do Dvele homes qualify for standard ADU permits in Sunnyvale?

Dvele ADU units can qualify under Sunnyvale’s pre-approved ADU plan program if the factory drawings match the city’s checklist for setbacks, height, and utility connections. We review the Dvele plan set against Sunnyvale’s current ADU requirements before permit submission, which avoids the weeks-long revision cycle that catches owners who submit factory drawings unmodified. Call (650) 405-3637 for a compliance review.

What should I do if I see cracks or drafts where the Dvele modules meet?

Document the location with photos and call us. Module seam cracks in Sunnyvale usually indicate differential foundation settlement, which will worsen through the dry season as clay soils contract. We prioritize these calls because the repair is simpler before the spline binds fully or the drywall tear extends into the corner bead. Call (650) 405-3637 - estimates are free.

Are Dvele’s factory-installed windows and doors covered if they start leaking?

Factory warranty coverage depends on the installation date and whether the leak stems from a manufacturing defect or transport/setting damage. We diagnose the cause before any claim is filed: if the sealant failed in transport, that’s a service issue we handle directly; if the frame extrusion is defective, we document it for your factory claim and perform the weatherproofing repair so your home is protected while the claim processes. Call (650) 405-3637 for diagnosis.

How do you handle Dvele roof repairs given the modular roofing system?

Dvele roof panels are prefabricated sections with integrated structure and finish, so we repair by section rather than shingle. For minor leaks, we reflash at the panel joints and upgrade the compression gasket to a stepped counter-flashing detail that handles Sunnyvale’s wind-driven rain. For extensive damage, we coordinate panel replacement with GAF or Owens Corning materials that match the factory R-value and meet Title 24 requirements. Roof repair in Sunnyvale typically runs $400-$1,800 depending on access and panel count.

How much does Dvele construction cost in Sunnyvale?

Dvele in Santa Clara and Sunnyvale ADU construction typically ranges from $90,000 to $220,000, including foundation work for expansive clay soils, utility tie-ins, and CalGreen Tier 1 compliance. Home additions run $45,000 to $130,000 depending on module count and structural tie-in complexity. Repairs for module seams, water intrusion, or roof flashing typically fall between $400 and $1,800. Every quote is a flat written price with line-item scope before work begins. Call (650) 405-3637 for an exact quote - estimates are free.
