Dvele Construction in San Antonio Heights, CA | Timberline Contractors
We provide independent Dvele construction service across San Antonio Heights, CA as a licensed general contractor who handles the site-side work a factory panel set can’t do for itself: county permitting, grading, foundation prep, panel setting, and the finish work that turns a panelized shell into a finished foothill home. What makes our Dvele work different here comes down to one thing: San Antonio Heights is unincorporated San Bernardino County, not the City of Upland, and every hillside Dvele job we touch gets plan-checked and inspected under county code. Call (866) 253-5808 to talk through your project.
Why San Antonio Heights Residents Choose Us for Dvele Service
We came to Dvele work through the foundation side of things, and that’s exactly where most panelized builds on these foothill lots need real attention. Nelson Fung, our owner and general contractor, spent years at Los Angeles Trade-Technical College and on job sites across the LA basin before Timberline took on our first panelized home, and he’ll tell you the same thing he tells every client: the panel is only as good as the base under it. On a sloped San Antonio Heights parcel with expansive clay, that base is everything — something we also address with our Rancho Cucamonga Dvele service.
We’re an independent Dvele service provider, not a factory-authorized dealer or installer. That independence matters because when a panel joint fails or a hold-down pulls loose, you want someone who will tell you the truth about whether the panel is the problem or the foundation is. We source genuine Dvele panel, connection, and flashing components where they’re still available for the assembly, and we match them against rated aftermarket structural connectors, sealants, and ember-resistant venting that meet the same engineering. For a full look at our brand-specific work, see our Dvele sales & service page.

Common Dvele Construction Problems We Solve in San Antonio Heights
- Panel-to-foundation separation and settlement cracking. Dvele’s rigid panel base sits on clay that swells with winter moisture and shrinks through hot, dry summers. On sloped San Antonio Heights lots, that movement concentrates at panel corners and hold-down points, producing stair-step cracks and gaps at the base connection. We re-anchor affected hold-downs to foundations that were often never engineered for panelized point loads.
- Roof-cassette and panel-seam flashing failures from Santa Ana wind uplift. The foothills get real wind, and Dvele’s factory flashing details weren’t always re-specified for what happens when a sustained northeast wind hits the roof-to-wall interface at an angle. We’ve seen seams peel, ember-laden air get into the envelope, and rain follow the same path.
- Foundation hold-down and sill-plate corrosion or pull-out. On original slabs and pier footings that predate panelized construction, the hold-down bolts carry loads they were never sized for. Corroded sill plates and back-out failures are common, and they’re a structural issue, not a cosmetic one.
- Moisture intrusion and sealant breakdown at panel joints on frost-pocket lots. San Antonio Heights gets winter frost pockets, and the freeze-thaw cycle stresses factory sealant lines at panel joints and eaves. Water works its way in slowly, then the first hard freeze pops the joint open wider.
- Grading and drainage failures that undermine the entire assembly. This is the unincorporated-county reality. If the hillside above a Dvele foundation wasn’t graded and drained properly, no panel assembly will stay tight. We fix the drainage first, then the structure.
Dvele Service in San Antonio Heights: What Local Conditions Mean for Your Equipment
San Antonio Heights is unincorporated, so a Dvele panel addition, ADU, or re-roof here is plan-checked and inspected by San Bernardino County, not the City of Upland. That single fact reshapes every project timeline. Hillside parcels in the 91784 ZIP typically trigger engineered grading and drainage review under county code, which means the county counter, not the factory panel set, is what actually sets the schedule on a Dvele job. We’ve had projects where the panel package was ready to ship while the grading plan was still in review. On a sloped custom-hillside lot off the foothill streets of San Antonio Heights, we opened up a Dvele panelized home where the roof cassette seams and panel-to-wall flashing had pulled apart after a couple of Santa Ana wind seasons, letting ember-laden air and rain into the envelope. We re-detailed the roof-to-wall junction with ember-resistant venting and rated flashing, replaced the failed sealant at the panel joints, and re-anchored the affected hold-downs to a foundation that had begun to move on the expansive clay, then documented the whole assembly for the county inspection. That’s the job: making the factory panel work with the county’s rules and the ground’s behavior. Our San Antonio Heights service area coverage includes the full foothill corridor.
Dvele Models & Products We Service in San Antonio Heights
We work on Dvele’s signature single-family panelized home, which pairs factory-built wall panels and roof cassettes with a pre-engineered foundation interface. We handle Dvele ADU and accessory dwelling panel packages from pad prep through final inspection. And we take on Dvele high-performance panelized custom estate builds on engineered foundations, the projects where a factory shell meets a one-off hillside lot and everything has to be reconciled on site.
Our parts approach is repair-first. We’ll replace a single failed panel joint or flashing line before recommending an assembly-wide replacement, and we’ll tell you honestly when the foundation, not the panel, is the real problem. Do it right the first time or explain yourself twice.

FAQs – Dvele Construction in San Antonio Heights
Yes. San Antonio Heights sits in a WUI-designated foothill zone, and any Dvele panel addition, kitchen extension, or re-roof should include ember-resistant venting, rated flashing at the roof-to-wall interface, and non-combustible exterior material choices where the county requires them. We work these details into the plan set from the first day. Call (866) 253-5808 and we’ll walk you through what your specific lot needs.
No. We’re an independent general contractor who works on Dvele’s panelized and modular homes on the site side: county permitting, grading, foundations, panel setting, and all finish construction. We source genuine Dvele components where available and match rated aftermarket alternatives where the factory part is discontinued or no longer specified for local conditions.
It depends on the county more than anything. A panel repair with no grading or drainage triggers can happen in days. A panel addition or ADU that requires engineered grading and drainage review typically adds weeks to the front end before any construction starts. We’ll give you a straight timeline after the first site visit.
We work on Dvele’s signature single-family panelized home, Dvele ADU and accessory dwelling panel packages, and Dvele high-performance panelized custom estate builds on engineered foundations. If you have a Dvele assembly that’s failing at the panel joints, roof seams, or foundation interface, call (866) 253-5808 for a free assessment.
Foundation work on expansive clay varies widely by lot slope, soil movement, and what the original pad actually was. Small hold-down repairs and crack stitching can run $2,000 – $6,000. A full re-anchoring or pier retrofit on a sloped parcel runs higher, and the only honest answer comes from a site visit. Estimates are free. Call (866) 253-5808.
