Cover ADU in Dallas | Ellery ADU Studio
We’re an independent design-build studio that services, repairs, and installs Cover in Irving and across Dallas. Our crew has torn into more Cover panel systems sitting on Blackland Prairie clay than any independent shop we know. We fix the foundation problems first, then the panels, and we document every step. If your Cover unit is shifting, cracking at the seams, or failing inspection, call (971) 497-2402 for a written price before any work starts.
Why Dallas Residents Choose Us for Cover Service
Cover builds a smart, steel-framed ADU. But in Dallas, the ground under it moves in ways the factory manual doesn’t fully account for. That’s where we come in. We know the S-Series, L-Series, and XL-Series panel systems well enough to diagnose a failing track or a separating joint without guessing, and we’ve done it on garage conversions from Oak Cliff to Lakewood. Nadia Ellery, our principal, studied architectural drafting and construction management at LATTC and has spent years focused exclusively on accessory dwelling units. She’s the reason our permit sets pass first review, which matters when your Cover unit needs foundation work that triggers a Dallas building permit.
We source genuine Cover clips, track sections, and panel gaskets whenever they’re available. When a part is discontinued or backordered for months, we machine high-gauge steel equivalents that match the original profile, not whatever’s cheapest at the supply yard. And we’re local to Dallas, which means when your Cover unit shifts after a wet spring, we’re not flying someone in from California to look at it.
Common Cover ADU Problems We Solve in Dallas
- Perimeter steel track buckling at slab corners. Dallas garages built before 1980 usually sit on unreinforced slabs. When those slabs shift more than two inches on reactive clay, the Cover track kinks at the corners and the wall panels start fighting each other. We see it most often in East Dallas and Oak Cliff.
- Panel joint gaps opening seasonally. Original installers sometimes anchor Cover base plates directly to clay without pier isolation. After one Dallas summer of 105-degree heat followed by a soaking October, the joints open up enough to let air and pests through. We fix this by re-seating panels on isolated piers, not by caulking the gap and hoping.
- Mini-split line sets pulling loose. The exterior wall of a Cover unit flexes with Dallas temperature swings. When the line set isn’t properly supported, that flex works the flare fittings loose and you lose refrigerant by July. We re-route and brace line sets so they survive a full summer.
- Roof panel uplift at the eaves. Spring microbursts in Dallas hit hard and fast. If the original anchor bolts have been sitting in humid clay soil for a few years, they corrode, and the roof panels start lifting. We replace anchors with corrosion-resistant hardware rated for local wind loads.
- Cover warranty void due to slab movement. Here’s what most Dallas homeowners don’t learn until it’s too late: Cover’s warranty doesn’t cover damage from foundation movement. When your unit is seated on clay that heaves three inches a year, the warranty is effectively gone. We fix the foundation so the unit stops moving, because patching panels on a moving slab is throwing money away.
Cover Service in Dallas: What Local Conditions Mean for Your Equipment
Dallas is the only major Texas city sitting entirely on the Houston Black clay of the Blackland Prairie. That clay swells up to 40% in volume between the wet season and the dry season. A Cover panelized ADU set on a standard slab will experience up to three inches of differential heave between the front door and the back wall every single year. The same unit in Fort Worth, on slightly less active clay, moves half as much. In Austin, on thinner soils, it moves less than that.
What this means for a Cover owner on North Winnetka Avenue in Oak Cliff is concrete: the steel frame doesn’t bend, so it transfers all that movement into the panel joints and the track connections. The panels don’t fail. The connections fail. That’s the thing to understand. You don’t replace a Cover ADU when it starts cracking. You fix what it’s sitting on and re-seat the panels. Last March, a homeowner asked us to build a New Detached ADU in Dallas from a 1962 garage, using a Cover L-Series 1-bed. When our tech pulled the base trim, we found the original galvanized track had kinked at both east corners. The slab had settled 3.1 inches toward the alley on that same clay everyone ignores. We saw-cut the slab, bored four 12-inch piers to 18 feet, poured a new post-tension slab, and re-seated the Cover panels with new shear clips. The city inspector signed off on the first pass.
Cover Models & Products We Service in Dallas
We service the full Cover residential line: the S-Series studio, the L-Series 1-bedroom, the XL-Series 2-bedroom, and the panelized Backyard Cottage shell. On parts, we use genuine Cover replacement clips, track sections, and gaskets when we can get them. When a part is discontinued or backordered, we machine a high-gauge steel equivalent in-house that matches the original profile and exceeds local wind-load standards. We keep common track sections, shear clips, and gasket profiles on hand for faster Dallas turnaround, because waiting six weeks for a factory part while your ADU sits open to the weather is not acceptable.
Cover Service Pricing in Dallas
Foundation repair on a Cover ADU in Dallas typically starts around $9,000 for a full slab demo and drilled-pier re-pour under a small studio unit, and runs higher when the existing garage slab is heavily tilted or the pier depth requirement increases. Panel re-seating and joint repair work usually falls between $2,500 and $6,000 depending on how many connections are compromised. Mini-split line set repair with refrigerant recharge runs $600 to $1,400. Every quote is a written, line-item price before work starts. That’s Haven Standard Clause 1, and it’s not negotiable. Call (971) 497-2402 for a written estimate.

FAQs - Cover ADU in Dallas
A Cover unit on an unreinforced Dallas garage slab will be out of level by more than the code allows before the inspector even arrives. The slab has usually settled two to four inches on the Blackland Prairie clay. The city inspector will flag it, and then you’re paying for foundation work anyway, plus a second inspection. Hire someone who prices the foundation from day one. Call (971) 497-2402 and we’ll give you a written price that includes it.
Yes, in most cases. Cover panels are designed to be lifted and re-seated. We unbolt the track, crane or jack the panels, pour the drilled piers and new slab, then re-seat everything with new shear clips and gaskets. The panels themselves usually survive. The connections are what failed. If your panels are structurally intact, reusing them saves you real money.
Dallas hits 100 to 110 degrees for weeks at a time. That heat pushes refrigerant pressures up, and if the line sets were not properly braced against the exterior wall flex, the flare fittings loosen and leak. By July, the unit stops cooling. We re-route line sets with proper support and check the charge before summer hits. An annual pre-summer check costs less than a July emergency call. Call (971) 497-2402 to schedule one.
Oak Cliff homes built in the 1940s through 1960s sit on pier-and-beam main houses with detached garages on unreinforced slabs. Those slabs move with the Houston Black clay. Newer subdivisions north of the city often have post-tension slabs from the start, or better site prep. The difference isn’t the Cover unit. It’s the foundation under it. Oak Cliff needs piers. Full stop.
Lakewood has some beautiful 1940s garages with good roof lines, but most sit on slabs that have tilted noticeably on the clay. In our experience, the roof can often stay if the structure is sound, but the slab usually has to come out. A Cover XL-Series 2-bedroom is heavy enough that a settled slab will cause problems fast. We’ll tell you what can stay and what has to go in the written estimate, before any work starts. Call (971) 497-2402 for that written price.
