Dvele Construction in San Antonio Heights, CA | Sycamore Contractors
We provide independent Dvele construction service across San Antonio Heights, from small envelope repairs to full home additions and ADU builds. What makes our Dvele work different here comes down to one thing: we understand how San Bernardino County’s wildland-urban-interface rules and steep foothill terrain change how a Dvele home has to be assembled, flashed, and finished. If you own a Dvele home in the 91784 ZIP and something isn’t performing the way it should, call us at (877) 265-6284 for a free estimate.
Why San Antonio Heights Residents Choose Us for Dvele Service
Dvele builds a genuinely tight, high-performance home. The panelized envelope, the factory-sealed assemblies, the continuous insulation – it’s a different animal than stick framing, and it demands a crew that has actually worked with the system. We have. Nate Calloway, who owns Sycamore Contractors, spent the better part of two decades running crews across Southern California before taking on Dvele modular and panelized builds in the foothill country above the valley. He’ll tell you straight: Dvele’s engineering is solid, but the details that win or lose a County inspection happen in the field, on your specific lot, with your specific slope and exposure.
We service Dvele homes throughout San Antonio Heights with an approach that respects the original system. For structural connections and envelope seals, we source OEM Dvele components so the build stays true to the manufacturer’s engineering. For finish hardware and trim, we’ll use quality aftermarket parts where performance is equal and lead time is better. You get a clear explanation of which is which before any work starts.

Common Dvele Construction Problems We Solve in San Antonio Heights
- Thermal bridging at panel joints. Dvele’s high-performance walls are excellent, but when foothill temperature swings run from 100-degree summer days to cold winter nights, panel joints can develop condensation and finish cracks. We see this most often on exposed hillside elevations in San Antonio Heights, where the sun beats on one wall while the shaded side stays cool. We repair the joint, restore the thermal break, and re-finish so the wall looks and performs right.
- Window and door gasket compression after Santa Ana winds. Factory-sealed Dvele assemblies are built tight, but sustained wind events can compress gaskets or degrade sealant, leading to air infiltration at rough openings. In San Antonio Heights, where Santa Anas funnel through the foothill canyons with real force, this failure mode shows up faster than it would on the valley floor. We re-seat or replace gaskets and re-seal openings using materials rated for the wind exposure.
- Roof-to-wall flashing that doesn’t meet WUI fire code. Dvele’s standard roof-to-wall flashing details often need field modification to pass San Bernardino County’s Class A fire-rated assembly requirements. Inadequate flashing at the soffit line means ember intrusion risk during wildfire season. We re-flash these junctions with ember-resistant materials and detail them to the county’s satisfaction.
- Foundation interface issues on sloped lots. Dvele’s standard anchor systems are engineered for flat or near-flat sites. On San Antonio Heights’ terraced hillside lots, where foundations step and pier-and-beam understructures are common, those anchors can meet uneven load transfer, causing floor squeaks and stress cracks if the modules aren’t properly shimmed and grouted. We correct the interface and restore even load distribution.
- Envelope seal degradation from high UV exposure. Inland foothill sun is relentless, and seals at module seams and penetrations can dry out faster here than in coastal climates. We inspect, identify dried or cracked seals, and replace them before they become water intrusion points.
Dvele Service in San Antonio Heights: What Local Conditions Mean for Your Equipment
Here’s the thing most Dvele owners in San Antonio Heights discover on their first project: because this community is unincorporated, every Dvele home addition, roof replacement, or ADU build here has to clear San Bernardino County’s WUI and slope-drainage review. That’s a completely different approval path than what homeowners in Upland or Rancho Cucamonga face. The county will require fire-resistant roof assemblies and engineered drainage plans that Dvele’s standard details simply don’t address. We saw this firsthand on a steep lot off one of San Antonio Heights’ hillside streets, where our crew completed a Dvele LUMEN Series home addition. The factory roof panels met a new Class A fire-rated assembly required by the county, and we had to re-flash the entire roof-to-wall junction with ember-resistant materials and add a drainage swale to direct runoff away from the foundation. The project passed county WUI inspection on the first try. That’s the level of local knowledge Dvele work in San Antonio Heights demands, and it’s not something a contractor who only works the flat subdivisions below will bring to your job.
Dvele Models & Products We Service in San Antonio Heights
We work on the full Dvele lineup, including the LUMEN Series, HARBOR Series, VISTA Series, and custom modular configurations. For structural tie-ins at module seams, roof connections, and foundation points, we keep OEM Dvele components on hand or sourced quickly through our supplier network. For finish trim, flashings, and hardware, we stock commonly needed aftermarket parts locally so a San Antonio Heights repair doesn’t stall waiting on a cross-country shipment. If your Dvele home needs a repair, our team can tell you on the first visit whether we’re working with OEM or aftermarket and why that’s the right call for your situation.

FAQs – Dvele Construction in San Antonio Heights
WUI review means your Dvele addition has to meet fire-resistant standards that go beyond standard building code. In San Antonio Heights, that typically means a Class A roof assembly, ember-resistant venting, and specific defensible-space clearances. We handle the county submittal and build your addition to pass the first time. Call (877) 265-6284 and we’ll walk you through the exact requirements for your lot.
Yes. Sloped lots in San Antonio Heights usually require stepped or pier-and-beam foundations, and Dvele’s standard anchor system has to be adapted at the interface. We shim, grout, and anchor the modules properly, and we engineer the drainage so runoff moves away from the structure. ADU construction here typically runs $90,000 to $220,000 depending on site work. Call (877) 265-6284 for a site-specific quote.
Class A fire-rated assemblies are the standard in San Antonio Heights, and metal roofing is a strong choice for the combination of fire resistance and longevity in hot, dry foothill conditions. We install metal roof systems from multiple manufacturers and integrate them with Dvele’s wall and soffit details so the whole envelope works as one system. Roof replacement here typically runs $8,000 to $20,000.
We identify the failed joint, remove the damaged sealant or gasket, restore the thermal break, and re-seal with materials rated for sustained wind exposure. Where finish cracks have formed from thermal movement, we repair and re-finish the surface so the wall looks original. The fix stops air infiltration and condensation at the source.
We do. Pier-and-beam foundations on San Antonio Heights hillsides shift over time, and Dvele’s anchor points can lose even contact. We re-shim the module interface, grout anchor points, and correct load transfer so floors stop squeaking and stress cracks stop spreading. Call (877) 265-6284 and we’ll inspect your foundation and give you an honest read on what’s needed.
