AfterDvele Construction in Pasadena, CA | Barrett & Sons Construction
We’re Barrett & Sons Construction, and we install, service, and repair Dvele panelized homes across Pasadena. We’re an independent Dvele service provider-not factory-authorized, not manufacturer-owned. What makes our Dvele work different here is simple: we’ve bolted Dvele’s factory-precise steel frames onto hundred-year-old foundations in Bungalow Heaven and Lower Hastings Ranch, and we understand what the seismic codes, fire zones, and historic districts in this city demand before the first panel arrives. Call (877) 610-1318 for a straight answer about your project.
Key takeaways:
- We’re an independent Dvele service provider serving Pasadena and nearby cities for over 29 years, founded in 1998.
- We’ve installed and serviced Dvele Signature Series, Architect Series, and panelized ADUs on pre-war Pasadena lots, including historic district properties.
- Permits pulled, inspections signed, and price changes in writing before work proceeds on every eligible job.
- Dvele panel seam repairs, foundation retrofits, and WUI-compliant roof replacements are all in our wheelhouse.
Why Pasadena Residents Choose Us for Dvele Service
We’ve installed and serviced Dvele’s panelized steel-frame and SIP envelope systems across dozens of pre-war Pasadena lots, from Bungalow Heaven to Lower Hastings Ranch. That hands-on work gives us real knowledge of how Dvele’s tight factory tolerances interact with 1905-1940 framing, historic district approvals, and seismic retrofits-things you won’t learn from a brochure. Tom Barrett founded Barrett & Sons in 1998, and he learned framing at Los Angeles Trade-Technical College, so none of this is theory. His sons run crews now, but Tom still walks jobs in Pasadena himself. We answer the phone when it rings, we pull permits on eligible jobs, and every scope change arrives as a written change order before a nail moves. Our 90-Day Done Right Promise is written on every contract. If it’s not done right, Tom comes back and makes it right-one call.
We also understand the Dvele-specific challenges Pasadena throws at a panelized home. This isn’t Arcadia or Monrovia. When a Dvele panel meets a plaster-and-lath wall on a 1921 Craftsman, the connection details matter. We get them right.
Common Dvele Construction Problems We Solve in Pasadena
- Panel-to-foundation seam separation: Older Pasadena lots in 91103 and 91104 sit on expansive clay with unreinforced masonry foundations. Dvele’s factory panels are precise; the ground under them isn’t. We see seam separation at the panel-to-foundation interface when differential settling pulls the steel frame against the original mudsill. We fix the connection and, where needed, retrofit the foundation first.
- Thermal bridging and condensation at steel frame connections: When Dvele panels attach to original plaster-and-lath walls on an addition, the steel frame conducts heat differently than the old envelope. Pasadena’s winter nights and hot summer days make condensation visible at those joints. We address the thermal break and re-detail the connection properly.
- Exterior cladding attachment failures in WUI zones: Foothill neighborhoods like 91107 sit inside CalFire-designated Fire Hazard Severity Zones. Santa Ana winds push against ignition-resistant cladding on Dvele panels, and poorly attached assemblies fail at the fasteners. We spec WUI-compliant fastening patterns that hold.
- Cripple-wall retrofit conflicts: Dvele panels bolted to pre-1940 structures without modern anchor bolts trigger mandatory seismic assessments, especially along Lake Avenue and Fair Oaks corridors. We’ve handled those retrofit scopes and know how Pasadena’s building department reviews them.
- Historic district cladding mismatches: A Dvele addition to a designated historic home in Bungalow Heaven or Prospect Park has to match original materials and roof pitch under Secretary of the Interior Standards. We clad factory panels with site-approved materials that pass Historic Preservation Commission review.
Dvele Service in Pasadena: What Local Conditions Mean for Your Project
Here’s the thing nobody tells you until the permit application stalls. Pasadena’s Historic Preservation Commission requires any Dvele addition to a locally designated historic home-the majority of housing stock in 91103 and 91104-to match original materials and roof pitch. That means our Dvele panel designs must be clad and detailed to pass Secretary of the Interior Standards. No generic Dvele installer from outside the city carries that knowledge. We do. On a 1922 Craftsman bungalow in Bungalow Heaven, our crew installed a 600-square-foot Dvele Architect Series addition. The original foundation lacked anchor bolts, so first we completed a city-mandated cripple-wall retrofit, then integrated Dvele’s steel frame with custom redwood shingle cladding to satisfy the Historic Preservation Commission. We used the Dvele factory connection kit but substituted WUI-rated fire-blocking foam around the SIP seams-passing both seismic and historic review inspection on the first pass. Neighboring Arcadia or San Gabriel won’t hit that double review. Pasadena will every time.
That’s the real cost driver and the real risk: a Dvele panel system is factory-perfect, but Pasadena’s rules are 1920s-perfect. We bridge both.
Why this matters for your job: If your Dvele project is in a historic district, plan for commission review from day one. We do. We submit drawings, spec compatible cladding, and schedule inspections so the project doesn’t stall mid-frame. Our Dvele sales & service knowledge is built on jobs exactly like yours.
Dvele Models & Products We Service in Pasadena
We service all three Dvele lines: Signature Series, Architect Series, and panelized ADUs. Our repair approach is straightforward-we source Dvele factory panels and proprietary connection hardware only from the manufacturer’s supply chain, but use locally approved, WUI-compliant sealants and fasteners where field conditions require. We repair before replacing when panel integrity holds. When thermal envelope or structural seams are compromised, we recommend panel replacement-honest advice, not upsell. Parts aren’t stocked in bulk because Dvele projects here vary; we order per job after a site visit and coordinate delivery to your Pasadena address.
We inspect panels, connections, and cladding on existing Dvele homes, and we fix what fails. If your project involves a Home Addition, ADU Construction, or Roof Replacement, we handle those too. Roof work in foothill ZIP 91107 means Class A roofing and ember-resistant vents when required-we spec that from day one.

FAQs - Dvele Construction in Pasadena
Yes, but not without extra steps. Any Dvele ADU in Bungalow Heaven or another Pasadena historic district must pass Historic Preservation Commission review and meet Secretary of the Interior Standards for exterior materials, roof pitch, and massing. The panelized structure itself doesn’t disqualify it-but the exterior cladding and roofline must match the district’s character. We handle the drawings, materials, and submittals. Call (877) 610-1318 to talk through your lot.
Usually, yes. Pasadena’s building department takes soft-story and cripple-wall conditions seriously, especially on pre-1940 homes. When you attach a Dvele panel system to a structure that lacks modern anchor bolts, the permit review typically flags the deficiency and requires a retrofit before framing proceeds. We scope that upfront so the price doesn’t surprise you later.
Most Dvele home additions in Pasadena land between $45,000 and $65,000 per square foot on the low end before historic or seismic scope. Foundation retrofit work adds $8,000 to $15,000 when required. An exact quote comes from a site visit-our estimates are free. Call (877) 610-1318.
They do where the city enforces Wildland-Urban Interface codes. In 91107 and other CalFire-designated Fire Hazard Severity Zones, exterior cladding, vents, and roof assemblies need Class A or ignition-resistant materials. We spec WUI-rated fasteners and sealants at every seam, and we use fire-blocking details that pass inspection.
First, we find out whether the failure came from soil movement or a bad connection. On a 1940s Pasadena lot with unverified bearing capacity, differential settling is the usual culprit. We repair the seam when the panel is structurally sound, and we typically recommend a foundation retrofit before reattaching anything. If the panel envelope is compromised, replacement is the honest call. We’ll show you the evidence and quote it in writing.
