Dvele Construction in San Antonio Heights, CA | Polaris Contractors
We provide independent Dvele construction service across San Antonio Heights, handling everything from room additions and ADUs to foundation retrofits on the steep foothill lots that define this ZIP code. What makes our Dvele work different here is the landslide and county-island permitting picture: homes on ancient landslide deposits often trigger LA County geologist review, soil reports, and caisson foundations even for modest additions. If you own a Dvele home in the 91784 ZIP and you’re planning any structural work, call us at (855) 473-6535 before you draw plans.
Our team has worked on Dvele sales & service projects across the San Gabriel foothills and understands the factory-built panel systems, connection brackets, and finish details that a flatland contractor will miss or fake. We’re an independent contractor. No manufacturer affiliation. That means we specify what the house actually needs, not what a factory rep wants sold. San Antonio Heights service area coverage includes the upper slope streets where foundation work gets complicated fast.
Why San Antonio Heights Residents Choose Us for Dvele Service
Dvele homes are built around the LUMEN, VISION, and ELEMENT modular series, with factory-sealed panels and proprietary steel connection brackets. The systems are good. What fails isn’t usually the factory work. It’s the interface: where a Dvele module meets a San Antonio Heights hillside, where factory flashing meets five months of dry heat then three weeks of storm rain, where panel seams meet soil that moves seasonally. That interface layer is what we understand.
Rick Sondermann, our owner, grew up in Corona del Mar and spent nearly three decades building and renovating homes from the Newport coast up into these foothills. His father was a finish carpenter who believed in doing things once and doing them right, and that philosophy stuck. When we take on a Dvele project in San Antonio Heights, we treat the factory structure with respect and the site conditions with suspicion. That combination keeps small problems from becoming structural ones.
We stock Dvele OEM connection brackets and proprietary flashing for the common failure points, and we keep tested aftermarket equivalents for standard fasteners and sealants. You won’t wait two weeks for a bracket when the fix takes a morning.

Common Dvele Construction Problems We Solve in San Antonio Heights
Here’s what we see most often on Dvele homes in this specific ZIP code:
- Panel-to-foundation connection corrosion. Hillside moisture and soil expansion work against Dvele’s steel brackets year after year. On terraced lots in San Antonio Heights, drainage from the slope above concentrates moisture at the foundation line. We replace corroded brackets with OEM hardware and re-grade where necessary.
- Window and door flashing failures. Factory-sealed flashing that holds up in a moderate climate gets hammered by foothill UV in summer and driven rain in winter. We see water intrusion at the head flashing first. The fix is removal, proper lapping, and re-sealing with materials rated for wildfire-zone UV.
- Settlement cracks at module joints. Dvele modules are joined at seams that sit right where a terraced lot wants to move. After a wet winter, those joints can open hairline cracks. Do not ignore them: on lots sitting on ancient landslide deposits, hairline cracks are the first sign of differential settlement.
- Fire-resistant detailing gaps at roof-to-wall intersections. San Antonio Heights sits in a high fire-severity zone. Roof-to-wall intersections are the weak point. We retrofit these junctions on Dvele homes with ember-resistant materials and proper flashing.
- Foundation movement under additions. When you add square footage to a hillside Dvele home, the new foundation and the original module foundation move at different rates. We sequence the work and specify connection details that accommodate that movement rather than fighting it.
Dvele Service in San Antonio Heights: What Local Conditions Mean for Your Home
The thing about San Antonio Heights that doesn’t apply one ZIP code over in Rancho Cucamonga or even Upland is the geology and the permitting path together. San Antonio Heights is an unincorporated county island. That means your Dvele project goes through LA County building officials and, often, LA County geologists, not a city plan checker who sees flatland tract homes all day. Homes on the upper slopes, along streets that climb toward the San Gabriels, frequently sit on ancient landslide deposits. Even a seemingly minor room addition can trigger a required soil report. And once the geologist is involved, caisson foundations are the usual answer.
We saw this play out on a steep lot off the upper slopes of San Antonio Heights. A Dvele LUMEN home had developed a hairline crack at the module joint where the kitchen addition met the original structure. The owner had been told it was cosmetic. It wasn’t. We traced it to differential settlement on the ancient landslide deposit beneath the addition, coordinated the LA County geologist’s soil report, and installed a caisson-supported foundation retrofit using Dvele OEM connection brackets before re-sealing the joint. The crack has not returned. Had that gone unexamined for another year, the repair would have been a teardown of the addition, not a retrofit.
Dvele Models & Products We Service in San Antonio Heights
We service the full Dvele range: LUMEN series homes, VISION series homes, ELEMENT series, and custom modular packages. That covers factory panel systems, structural connection brackets, module joint flashing, envelope penetrations, and roof systems. We use Dvele OEM parts for structural connections and proprietary flashing. For standard components like fasteners and sealants, we use tested aftermarket equivalents that match or exceed the spec. We keep the common OEM brackets and flashing profiles on hand or available within a day for San Antonio Heights jobs, so you’re not waiting on a factory shipment to move the project forward.
When a module has repairable joint or finish damage, we repair. We don’t push replacement. Replacement only becomes honest when the structural panel itself is compromised, and at that point we’ll show you why with photos and measurements, not sales language.

FAQs – Dvele Construction in San Antonio Heights
Yes, in most cases we can. The catch is that hillside lots in San Antonio Heights often sit on ancient landslide deposits, and LA County will likely require a geologist’s soil report before permitting. If the report calls for caissons, that adds cost and time, but we’ve done these retrofits and additions before. Call (855) 473-6535 and we’ll give you an honest read on your specific lot.
Yes. San Antonio Heights is an unincorporated county island, so ADU permits go through LA County, not a city building department. The county reviews hillside stability, septic capacity (many homes here are on septic, not sewer), and fire zone requirements. We handle the permitting and coordinate the engineering, which is usually the slowest and most expensive part of a Dvele ADU here.
We open the joint, remove the failed flashing, inspect the connection bracket for corrosion, replace any compromised parts with Dvele OEM hardware, and re-seal with materials rated for our UV and rain conditions. The repair itself often takes one day; the inspection of what’s underneath is what tells us whether the water did structural damage that needs more. Call (855) 473-6535 and we’ll come look.
For the fire zones in the San Antonio Heights foothills, a Class A metal roof is the smartest long-term choice. It handles the ember risk better than eaves and shingle intersections. We also retrofit the roof-to-wall junction with ember-resistant detailing for Dvele homes where the factory assembly left gaps. The cost depends on roof size and slope, but it’s one of the best fire-hardening investments you can make here.
It depends on the location, width, and whether the crack is moving. Hairline finish cracks at seam tape are usually cosmetic. Cracks that open wider, run through the panel itself, or appear at module joints on a sloped lot can be the first sign of settlement or foundation movement. On San Antonio Heights hillsides, we don’t tell homeowners to “watch and wait.” If you see cracks, call us at (855) 473-6535. A quick inspection settles the question.
