Dvele Construction in Sunnyvale, CA | Daly City Construction
We provide independent Dvele construction service across Sunnyvale, covering panel repairs, ADU builds, additions, and roof work on Dvele ONE, TWO, and ADU models. The thing that makes our Dvele work here different is simple: this is a city of Eichlers, radiant slabs, flat roofs, and tree ordinances that force custom crane positioning on tight lots. Most contractors meet those conditions once. We have built enough Dvele projects in Sunnyvale that we plan for them from day one. Call (866) 505-5254 for a free estimate, and read on for what Dvele ownership actually looks like in this city.
Why Sunnyvale Residents Choose Us for Dvele Service
Dvele builds a genuinely advanced panelized system. But a high-performance envelope only stays high-performance if the crew touching it understands thermal bridging, air-sealing continuity, and low-slope drainage. That is where we come in. Our team has completed multiple Dvele builds and retrofits in Sunnyvale, from a Dvele ONE ADU on an Eichler lot to panel replacements on existing homes. We also offer Mountain View Dvele service for homeowners just north of the city. Noel Cabrera, our owner, grew up around Daly City’s postwar tract homes and trained in construction technology at City College of San Francisco. He has spent years on residential work throughout San Mateo and San Francisco counties, and he brings that same straight-talking approach to every Dvele job: name the problem, explain the fix, use the right part, move on.
We are an independent Dvele service provider. We are not manufacturer-affiliated or authorized. That independence matters because it means we have no reason to push a module replacement when a repair is the honest call, and no reason to cut corners on aftermarket parts when genuine components are what the structure needs. We also maintain working relationships with Dvele sales & service channels for sourcing panels and connection hardware, which keeps turnaround reasonable for Sunnyvale homeowners.

Common Dvele Construction Problems We Solve in Sunnyvale
Every prefab system has failure points. In Sunnyvale, the local climate and housing stock push Dvele into a specific set of them. Here are the five we see most often when we are called out across Sunnyvale service area ZIP codes 94085, 94086, 94087, and 94088:
- Panel joint separation at floor-to-wall connections. Sunnyvale’s mild but thermally variable climate cycles between cool fog mornings and hot inland afternoons. Dvele panels expand and contract enough that original joint sealants eventually fail, opening air-infiltration paths and energy loss. On the 94087 ADU project we completed, we replaced affected panels with genuine Dvele components and reinstalled a flexible sealant rated for these temperature swings.
- Moisture intrusion at window and door penetrations. Dvele’s proprietary flashing system was not designed to tie into the original flat-roof conditions on many mid-century Sunnyvale homes. When a Dvele addition meets an Eichler-era post-and-beam roof, the transition can allow water to track inside, causing staining and mold risk behind the trim. We reflash and retape these interfaces properly.
- Foundation interface problems on radiant-heated slabs. A Dvele module set directly on an original 1950s-60s slab with radiant heating sees uneven thermal expansion. That movement cracks floor finishes and can compromise the structural connection at the module base. We inspect the slab, isolate movement where needed, and re-anchor the module correctly.
- Roof ponding on low-slope Dvele roofs. Sunnyvale gets almost no snow, but its winter rain arrives in concentrated bursts. Many Dvele roof sections use scuppers sized for average rainfall, not the heavy single-storm events common here. Standing water leads to premature membrane failure. We inspect drainage and, where needed, resize scuppers or add tapered insulation to direct water off the roof.
- Wrong flashing or incompatible sealants from prior repairs. We routinely find Dvele homes where a previous contractor used a standard silicone over a moving panel joint. The joint fails again within a season or two. We strip the old sealant, evaluate movement capacity, and install a product matched to the actual joint condition.
Dvele Service in Sunnyvale: What Local Conditions Mean for Your Equipment
The one Sunnyvale factor that changes everything on Dvele projects is the city’s tree-preservation ordinance. Before any construction within the drip line of a protected tree, the city requires a review by a city arborist. That review can stall a Dvele module placement for weeks and, more importantly, can force custom crane positioning on lots that are already tight. On a typical Eichler lot in 94087, the crane has to thread between the existing home, the property line, and a mature oak that cannot be limbed without a permit. That is not a hurdle you will find in Cupertino or when arranging Santa Clara Dvele service nearby. In Sunnyvale, it is the reality of nearly every ADU or addition we build. We sequence our Dvele projects around the arborist review, and we include crane access planning in our site walk before we ever submit drawings. If you are adding a Dvele ADU to a property with a protected tree, that planning is the difference between a build that starts on schedule and one that sits dead in permitting for months.
Dvele Models & Products We Service in Sunnyvale
We work on all three Dvele product lines: the Dvele ONE single-family modular home, the Dvele TWO two-story modular, and the Dvele ADU. For structural work, we source genuine Dvele replacement panels and connection hardware. Non-structural parts such as trim, sealants, and flashing are matched with high-quality aftermarket equivalents that meet or exceed OEM specification. Locally, we stock the fast-moving items: flexible panel-joint sealants, low-slope roof patch materials rated for ponding exposure, and flashing components compatible with Eichler-era roof transitions. That stock means we can often start a Sunnyvale repair without waiting days for shipped parts. When a full module replacement is under consideration, we give you the honest cost comparison between repair and replacement, and we let the numbers make the case.

FAQs – Dvele Construction in Sunnyvale
Yes. The critical step is reflashing the panel junction where it meets the original flat-roof structure, because that transition is where most moisture intrusion starts on Eichler-era homes. We repair the panel, rework the transition, and test the area for airtightness before we finish. Call (866) 505-5254 to have a specific condition assessed.
Sunnyvale’s building division is among the strictest in the county, and when a protected tree sits within the drip line of your planned ADU, the city arborist review is mandatory before placement approval. That review alone can add weeks to a project. We build that time into the schedule and sequence site work so the arborist review does not idle the rest of the job.
Roof repair on a Dvele home in Sunnyvale typically runs $400 to $1,800 depending on panel size, membrane condition, and whether drainage scuppers need resizing. If it is a small area, a targeted membrane replacement usually handles it. If the panel underneath has delaminated from prolonged ponding, we will quote a panel replacement. Call (866) 505-5254 for an exact number after we inspect the roof.
We do. A second-story addition on a 1950s or 1960s Sunnyvale ranch means tying Dvele’s panelized wall and roof assemblies into an existing single-story frame. The key detail is the floor-to-wall connection at the new level: we specify hardware and sealants that accommodate differential movement between the original stick framing and the Dvele panels. We bring the same rigor to Dvele repair in Loyola and surrounding neighborhoods.
We start with a slab inspection to understand exactly where the radiant tubes run and how stable the slab is. When the ADU footprint sits over or near an original slab, we install an isolation layer or design a shifted foundation so the radiant heating cycles do not move the Dvele module. That approach has prevented the floor-cracking problem we have seen on projects where the module was set directly on the old slab without isolation.
