Dvele Construction in Pomona, CA | Timberline Contractors
We provide independent Dvele construction service across Pomona and nearby communities, from Dvele in La Verne to panel tie-ins on century-old bungalows near Lincoln Park and full Dvele ADU builds on the east side. What makes our Dvele work different here is that we start where Pomona actually starts: with the foundation. Most Pomona lots with older housing stock sit on raised pier-and-beam supports that have settled or rotted through decades of dry-summer/wet-winter cycling, and no factory panel can be set to tolerance until that’s fixed. We’re Timberline Contractors, led by Nelson Fung, and our crews set, tie in, and re-detail Dvele panelized assemblies across the San Gabriel Valley and Inland Empire edge. Call (866) 253-5808 for a free estimate.

Why Pomona Residents Choose Us for Dvele Service
We’ve had to solve Dvele connection and tolerance issues on real Pomona sites, not in a training room. The factory didn’t send us. Our crews work to Dvele’s factory connection and tolerance specs because we’ve seen where they hold and where they fail when the ground under them moves. That’s the difference between a contractor who installs Dvele panels and one who understands what happens to them on Pomona’s expansive clay and raised foundations.
Nelson Fung, our owner and general contractor, learned the trade at Los Angeles Trade-Technical College and spent years swinging hammers on everything from Eastside bungalow remodels to mid-size commercial builds across the LA basin. He grew up watching his grandfather debate tile prices at the hardware stalls on Broadway in Chinatown, which is probably where the obsession with materials started. Today that means we use Dvele’s factory connection hardware and specified sealants wherever the assembly’s engineering depends on them, and quality aftermarket flashing, fasteners, and cladding only where the spec allows. Dvele sales & service is what we do, but Pomona foundations are what we know.

Common Dvele Construction Problems We Solve in Pomona
Here’s what we see when Dvele panel systems run into Pomona’s older housing stock and climate:
- Panel-to-foundation connections that lost tolerance. Pomona’s raised bungalow lots are the usual culprit. Our crew finds settled or rotted piers under a room-add tie-in before any Dvele panel goes down, and we re-level and re-pier before setting panels. Skip that step and the factory tolerance is already blown before the first fastener goes in.
- Roof-to-wall flashing and panel-joint sealant failure. Pomona’s summer heat dries and cracks stucco and seam sealant, then the first heavy winter rain finds every compromised joint. We see this most often where Dvele roof cassettes meet existing stucco walls on 1960s-era tract homes on the east side.
- Expansive clay movement racking panel joints. The valley floor under Pomona holds expansive clay that swells and shrinks with seasonal moisture. Dvele panels set to a flat pad with no allowance for that movement will open seams at corners and window openings within a couple of years.
- Factory-tolerance mismatch with lath-and-plaster walls. In Pomona’s 1900s – 1940s bungalow neighborhoods, a Dvele panel often butts against original lath-and-plaster or stucco-over-no-sheathing walls. The connection point between a factory-true panel and a hand-built 1920s wall needs real detailing work, not a bead of caulk.
- Stucco tie-in failures at panel edges. Where a Dvele panel meets an existing stucco wall, the transition cracks along the panel edge as the two systems move differently. We re-detail those transitions with proper flashing and control joints before they leak.
Dvele Service in Pomona: What Local Conditions Mean for Your Equipment
Here’s the thing most generic Dvele pages won’t tell you, and it’s specific to Pomona. The older bungalow neighborhoods here were largely built on raised pier-and-beam foundations, not slabs. So a Dvele addition or ADU in Pomona usually starts with re-leveling and re-piering the existing structure before a factory panel set can be tied to it. That’s a pre-framing step that a slab-on-grade tract city like neighboring Chino or Ontario rarely forces, though we’ve handled similar foundation work for Dvele service in Claremont. When we tie a Dvele panel into a home near Garey Avenue or Holt Boulevard, we assume the existing piers have moved. We inspect them, re-level what’s needed, and only then do we set the factory panels to Dvele’s connection spec. That means our Pomona Dvele projects carry a foundation scope that a generic panel installer won’t even look for, and it’s why our projects close in tight while others open up at the corners within a season.
On a Lincoln Park-area bungalow off the downtown grid, the owner wanted a Dvele panel addition on the back of a 1920s Spanish Colonial. Our crew found the original pier-and-beam supports had settled and rotted through decades of dry-summer/wet-winter cycling. We re-leveled and re-piered the existing footprint, then set the Dvele wall and roof panels with upgraded flashing at the roof-to-wall junction and stucco tie-in to the lath-and-plaster wall. The addition closed in tight ahead of the winter rains. That’s the work a Pomona Dvele project actually requires.
Dvele Models & Products We Service in Pomona
We work on the full Dvele product range: modular and panelized single-family home packages, Dvele ADU and accessory dwelling panel packages, prefabricated wall and roof cassette systems used in additions and infill builds, and Dvele high-performance envelope assemblies with continuous insulation and factory-set panel joints. When a panel joint or sealant has failed, we repair and re-detail rather than quoting a panel replacement. Full replacement only happens when the structural panel or cassette itself is compromised. We keep Dvele-compatible connection hardware, specified sealants, and the flashing profiles we use most often in Pomona stock, which means faster turnaround when a seam opens up on a Ganesha Hills home, a Philips Ranch addition needs a tie-in detail corrected, or a homeowner calls us for Dvele repair in Montclair.

FAQs – Dvele Construction in Pomona
Yes, it can go onto the existing pier-and-beam foundation, but only after we re-level and re-pier the settled or rotted supports. In Pomona’s older core near the downtown grid, we almost always find original piers that have moved, and setting factory panels to tolerance requires a stable base first. It’s rare that the entire foundation needs replacement. Call (866) 253-5808 for a free inspection and a straight answer on your specific lot.
Expansive clay expands when wet and shrinks when dry, and Pomona’s dry-summer/wet-winter cycling drives that movement every year. A Dvele panel set to a flat pad with no allowance for seasonal soil movement will rack at the panel joints and open seams at corners and window openings. We account for the clay with proper pad design and connection detailing so the assembly moves as one system instead of working against itself.
The city requires the same permits, inspections, and code compliance as any ADU, but panelized construction usually means more scrutiny on the panel-to-foundation connection and the engineering documents from the factory. We pull permits, schedule inspections, and keep the paperwork straight so your Dvele ADU passes without a surprise correction list. Call (866) 253-5808 and we’ll walk you through what Pomona’s building department will ask for.
Pomona’s summer heat dries and cracks the sealant, then the first heavy winter rain finds every compromised joint. On a newer build the connections are fresh and the sealant is intact. On an older Pomona home, the existing stucco or lath-and-plaster wall has already been through decades of that cycling, and the tie-in point between old wall and new panel is where the movement concentrates.
No. We’re an independent contractor, not manufacturer-affiliated or authorized by Dvele, and we say so plainly. Our crews work to Dvele’s factory connection and tolerance specs because we’ve had to solve them on real Pomona sites, not because the factory sent us. That independence means we recommend repair over replacement when it’s the right call, and we never upsell you on parts you don’t need.
