AfterDvele Construction in Bonita, CA | Rowan Construction Group Chula Vista
We provide independent Dvele construction service across Bonita, CA, specializing in SIP panel repairs, roof replacements, and additions on Dvele’s LUMEN, VISION, ELEMENT, and Custom Series homes. The one thing that sets our Dvele work apart in Bonita is our fluency with San Diego County’s unincorporated permitting process, including the dual-agency reviews that catch most out-of-town contractors off guard when work touches equestrian structures or ADUs on large-lot horse properties. Call (619) 536-0571 to schedule your free estimate.
Why Bonita Residents Choose Us for Dvele Service
We’ve completed dozens of projects using Dvele sales & service panelized wall, floor, and roof systems, from structural repairs to full finish work on their high-performance home packages. Our crew understands Dvele’s precise engineering, from SIP panel joinery to integrated MEP chases, and we apply that knowledge to every remodel or repair we take on in Bonita.
Grant Rowan, our owner, grew up watching older homes get flipped carelessly in Beverly Hills. He trained in construction technology at West Los Angeles College, then spent nearly two decades working through every phase of residential construction before founding Rowan Construction Group in 2007. His crew has framed additions in Rancho del Rey, pulled permits at the Chula Vista Civic Center, and handled scopes that most outfits either underestimate or overprice. Grant still shows up in boots on day one of every project. He hasn’t found a better way to take a measurement than standing on the site himself.
Under Clause 1 of The Haven Standard, every project gets a written price before any work starts. No exceptions. Our 365-Day Done Right Promise means if it is not done right, we make it right, backed by a terms page you can read, not an asterisk. We also offer a Free Second Opinion on any written estimate, line by line, at no charge.
Common Dvele Construction Problems We Solve in Bonita
- Panel seam separation and air infiltration - Bonita’s canyon-rim temperature swings and high winds stress Dvele’s SIP joints. The daily expansion and contraction cycles open gaps that standard caulk won’t hold. We remove the failed sealant, inspect the OSB facing for delamination, and reinstall with proper vapor-open tape and compatible foam.
- Roof membrane or flashing failures - Intense sun exposure on Dvele’s flat or low-slope roof assemblies degrades the membrane faster than pitched alternatives. When seasonal rains follow, moisture intrudes at panel edges. We trace the leak path, replace compromised panels if structural integrity is lost, and upgrade to a more robust flashing detail.
- Foundation settlement cracks transferring into structural panels - Bonita’s clay-heavy hillside soils shift with moisture changes. That movement cracks slabs and transfers stress into Dvele’s rigid panel system, causing door and window misalignment and drywall cracking. We stabilize the foundation interface, then relevel and reseal the panel connections.
- Ember intrusion at vent penetrations or panel gaps - Homes in the county’s High Fire Hazard Severity Zone, including canyon-rim properties in Bonita, require Chapter 7A ember-resistant construction. Standard Dvele vent details may not meet this standard. We retrofit with 1/8-inch mesh screening, intumescent sealants, and proper soffit enclosure.
- Flood-zone moisture compromise along north walls - Properties near the Sweetwater River valley face FEMA flood-zone requirements. We recently repaired a Dvele LUMEN Series home where flood-zone moisture had compromised the SIP panel seams along the north wall, causing air infiltration and minor mold. After coordinating with county inspectors for flood-resistant repairs, we replaced the affected panels, resealed all joints, and upgraded the drainage, restoring the home’s airtight envelope without a full rebuild.

AfterDvele Service in Bonita: What Local Conditions Mean for Your Equipment
Bonita is unincorporated San Diego County. Every permit, every inspection, every plan check runs through the county’s Department of Planning & Development Services. Contractors who know Chula Vista’s city building department are routinely surprised by county timelines, county fire overlay requirements, and the separate county grading ordinance that governs Bonita’s hilly terrain.
For Dvele owners, this matters in specific ways. A roof replacement on a VISION Series home in the canyon rim triggers Chapter 7A material requirements that a standard permit wouldn’t include. An ADU on a half-acre horse property off Bonita Road or near the Sweetwater valley starts with Planning, then gets routed to Agriculture for equestrian structure review. That dual-agency coordination adds weeks. We’ve seen contractors submit once, wait, then learn about the second review only after the first approval came through. We build that timeline into our schedule from the start. “Measure twice, document once, build it so you never have to come back.” That’s how we avoid the surprises that derail Dvele projects in Bonita.
Dvele Models & Products We Service in Bonita
We work on all Dvele model lines: the LUMEN Series with its emphasis on open plans and natural light; the VISION Series with its integrated smart-home infrastructure; the ELEMENT Series with its more compact, efficient footprints; and the Custom Series where Dvele’s engineering adapts to owner-specific architecture.
For repairs, we source Dvele-specific OEM replacement panels and connectors when available. For non-structural components, trim, sealants, and flashing, we use tested, code-compliant aftermarket equivalents that meet or exceed the original spec. Our Bonita warehouse stocks common SIP panel tape, compatible closed-cell foam, and Chapter 7A-rated vent mesh for same-week turnaround on most service calls. We’ll always give you an honest repair-vs-replace assessment. Many Dvele panel issues can be locally repaired without full replacement.
Dvele Service Pricing in Bonita
Our written quotes use flat pricing with a written scope. No change proceeds without a signed change order. That’s the discipline that has kept our projects within a few percent of the agreed cost across 4,000-plus jobs since 2007.
| Service | Price Range in Bonita |
|---|---|
| Kitchen Remodel | $14,000-$45,000 |
| Roof Replacement | $8,000-$20,000 |
| Home Addition | $45,000-$130,000 |
What drives cost: Dvele’s panelized construction requires precise sequencing. Removing a kitchen wall for a Bathroom Remodeling in Bonita project means understanding the SIP load path first. Adding a room means matching the existing panel thickness and connection detail. County permit fees for unincorporated Bonita run higher than Chula Vista’s city fees, and dual-agency reviews add administrative time. We include all of this in the written quote. Every customer receives a documented photo record of existing conditions before work begins. Call (619) 536-0571 for your exact numbers. Estimates are free.

FAQs - Dvele Construction in Bonita
Yes. We stabilize the foundation interface, relieve stress on the panel connections, then reseal or replace affected SIPs depending on structural damage. Most cases don’t require full panel replacement. Call (619) 536-0571 and we’ll assess the crack pattern and give you a written repair scope.
Yes. We pull all permits through San Diego County Planning & Development Services, including the grading permits and fire-overlay clearances that unincorporated Bonita requires. If your property includes equestrian structures, we coordinate the Agriculture department review simultaneously rather than sequentially, saving weeks. Call (619) 536-0571 to review your parcel’s specific requirements.
Chapter 7A of the California Building Code requires ember-resistant materials and sealed eave and soffit assemblies. For Dvele’s low-slope roof designs, this means upgraded vent screening, intumescent sealants at panel joints, and often a Class A fire-rated membrane where the original spec used a lower rating. We specify these upgrades in the written quote. Call (619) 536-0571 for a roof assessment that includes fire-zone compliance.
Yes, if the airtight envelope is maintained. We preserve existing SIP panel integrity, use compatible sealants at any new penetrations, and verify blower-door performance after electrical and plumbing rough-in. The key is sequencing: structure first, then MEP, then air-sealing verification before finishes. Call (619) 536-0571 to schedule a Kitchen Remodeling - Bonita estimate with energy performance included in the scope.
Plan for 8-14 weeks of permitting before construction starts. The county Planning review takes 4-6 weeks, and the Agriculture department review for equestrian structure proximity adds another 3-6 weeks if submitted separately. We coordinate both from day one. Construction timeline depends on ADU size and utility connections, typically 3-5 months. Call (619) 536-0571 and we’ll map the specific timeline for your parcel.
