Dvele Home Addition Contractor in San Antonio: What to Know First

We’re an independent Dvele home addition contractor serving San Antonio, and we handle room additions, second story additions, and bump-outs for Dvele owners who need more space without losing the clean lines their home was built with. Most Dvele additions in San Antonio run between $185 and $340 per square foot depending on finish level, roofline complexity, and how much structural connection work the existing panel system requires. You’ll get a written price before any work starts, no verbal ballparks that drift later.

This page is for Dvele homeowners in San Antonio who want a contractor that actually understands their home’s panelized construction instead of treating it like a stick-built ranch house from 1987. Call (430) 258-2928 and a live person answers, day or night.

How Dvele Products Fail – and How We Fix Them

Dvele builds with prefabricated steel-framed panels, which means the failure points on a home addition are different from what you’d see on a conventional wood-framed house. Here’s what we encounter most often on San Antonio Dvele jobs:

• Panel joint separation at the existing structure connection. Dvele homes are modular by design, and where an addition ties into the original envelope, thermal movement between steel panels and the existing foundation creates hairline gaps at the seam. We see this on Dvele’s D187 and D230 models, especially after San Antonio’s wild temperature swings between August heat and February cold snaps. We open the seam, install a proper expansion channel, and re-flash the transition so it moves without cracking.
• Roof membrane failure at parapet intersections. Dvele’s flat and low-slope roof profiles use a continuous membrane system, but at the parapet wall where an addition meets the existing roofline, poor original detailing leads to ponding water and eventual leaks. We strip back the membrane, rebuild the parapet termination with proper drainage mat, and re-seal with a TPO-compatible system that matches what Dvele originally spec’d.
• Window and door rough-opening drift in panel seams. Because Dvele panels are factory-cut, field modifications during a San Antonio addition can leave window and door openings slightly out of square when the new panels settle. You’ll notice sticky doors or windows that bind at the header within the first year. We re-shim the opening, verify the header load path, and reset the flashing so the unit operates clean again.
• Stucco and exterior finish cracking over panel joints. Dvele’s exterior cladding systems hide panel seams, but San Antonio’s clay soil expands and contracts with moisture, and that movement telegraphs through the finish as vertical hairline cracks. The fix is not just patching the stucco; we backer-rod the joint, install a proper joint treatment, and refinish so the seam can flex without re-cracking.
• Moisture intrusion at cantilevered bump-out transitions. Bump-out additions on Dvele homes create a ledger point where the cantilever meets the main panel wall. If the original flashing was done with standard housewrap tape instead of a fluid-applied membrane, you get slow water wicking into the steel frame. On the D165 line we’ve seen this at the floor transition. We remove the bottom panel trim, inspect the ledger, replace any corroded connectors, and re-apply a proper peeling-stick membrane before reinstalling.

Our Dvele Home Addition Contractor Process

Every Dvele addition we build in San Antonio follows the same path, and you’ll know exactly where things stand at each step. No disappearing acts, no “the engineer is out of town” phone calls.

1. 1
   Site walk and panel assessment. We inspect the existing Dvele structure, measure the panel connection points, and document the roof and foundation condition. You get photos of everything we find.
2. 2
   Written scope and price. Before any work starts, you get a line-item proposal with real numbers. Troy Eastman puts the number on paper first. Everything else follows from there.
3. 3
   Engineering and permit package. We pull the structural engineering for the addition’s connection to your Dvele system, and we file the permit paperwork with San Antonio’s development services department. You don’t chase anything.
4. 4
   Foundation and panel installation. We pour or tie in the foundation per plan, set the new panels, and weatherproof the seam between old and new immediately. No exposed framing left to the elements overnight.
5. 5
   Interior finish and system integration. We tie electrical, HVAC, and plumbing into the existing Dvele infrastructure, then finish drywall, flooring, and trim to match your current interior. Before-and-after photos included.
6. 6
   Final walkthrough and written guarantee. We walk the project together, sign off the punch list, and hand you our 365-Day Done Right Promise in writing. If anything’s wrong within a year, we come back and make it right.
