Cover ADU in Arlington, CA | Ellery ADU Studio
We provide independent Cover ADU service across Arlington, handling everything from foundation correction and panel upgrades to full unit retrofits. We also offer Fort Worth Cover service for properties just west of the metroplex. One factor separates our Cover work here from anywhere else: Arlington sits on Blackland Prairie clay that moves enough to rack a modular steel frame if the slab wasn’t engineered for it. We’ve built our entire Cover practice around that soil. If you’re weighing a Cover unit in Arlington or already own one, call (971) 497-2402 for a written price before any work begins.
Why Arlington Residents Choose Us for Cover Service
We’ve spent years working with Cover’s modular steel-and-glass system, which means we know where these units fail and what fixes actually hold. In Arlington specifically, that knowledge matters more than in most markets. A Cover unit installed on a generic slab will move when the clay beneath it shrinks in July and swells in April. We catch that before the inspector does. We also carry Cover-specific structural connectors and panel gaskets from the manufacturer’s licensed supply chain, so warranty coverage stays intact while we work. Nadia Ellery founded this studio in 2015, and her crew has been hands-on with every phase of residential design-build since. We’re not a Cover authorized dealer; we’re an independent shop that has simply done the homework. That independence means we tell you when a part should be OEM and when an aftermarket component does the same job for less. Our Cover sales & service work is built around that judgment.
Common Cover ADU Problems We Solve in Arlington

Here’s what we see most often when Cover units in Arlington start showing problems.
- Frame racking from slab movement. Arlington’s expansive clay swells with spring rain and shrinks hard through dry summers. A Cover S or C Series bolted to an under-engineered slab will twist, causing wall panels to fall out of alignment and doors to bind. The fix starts below grade, not at the frame.
- Mini-split systems undersized for 105°F weeks. Factory specs for Cover’s heat pumps often assume a milder climate. When August heat indexes in Arlington pass 105°F, those units run constantly and still can’t hold setpoint. We replace them with correctly sized systems and verify airflow through the unit’s glass-heavy envelope.
- Tripped breakers on 100-amp service. Most Arlington homes built between 1960 and 1985 came with 100-amp panels. A Cover unit’s all-electric appliances, heat pump, and induction cooktop overload that panel fast. We upgrade to 200 amps before the main breaker starts nuisance-tripping during a game-night rental.
- Roof-to-wall leaks during spring storms. Cover’s flat-roof profile works fine in dry climates, but Arlington’s heavy spring rains expose any gap in flashing at the junction points. DIY installs skip this detail often. Water intrusion then shows up as condensation streaks on interior glass panels.
- Condensation at panel joints in humid months. The steel frame cools faster than the surrounding air during shoulder seasons. If gaskets between modules were compressed incorrectly at install, that condensation migrates inward and damages interior finishes. We re-seat or replace those gaskets properly.
Cover Service in Arlington: What Local Conditions Mean for Your Equipment
Arlington holds a distinction that quietly reshapes every Cover ADU decision here: it’s the largest U.S. city without a fixed-route public bus system. That means every person living in a backyard Cover unit drives a car, and Arlington’s zoning code responds by requiring garage conversions and new accessory units to preserve covered parking on the same parcel. For a Cover owner, that requirement pulls the conversation toward the narrow S Series. A wider C or M Series eats enough rear yard that the required carport no longer fits without a setback variance, and Arlington’s planner’s office grants those sparingly. We’ve taken clients through this exact sequence enough times that we now bring a parking plan to the first site visit. It saves a project that otherwise stalls at plan check. This is the kind of detail that generic Arlington service area pages never connect to a specific product line.
Cover Models & Products We Service in Arlington

We work on every Cover model currently in production: the S Series studio, the C Series one-bedroom, the M Series two-bedroom, and the Accessory Unit line. Our parts discipline is simple. Frame members, panel gaskets, and structural connectors come only from Cover’s licensed supply chain, because using anything else voids the factory warranty and compromises the module-to-module connections the system depends on. For replaceable items like mini-split filters, moisture barriers, and interior trim, we use quality aftermarket parts where they make sense. If a Cover frame member is warped beyond shimming or a wall panel has delaminated, we recommend replacement over patching every time. A modular steel unit loses its structural logic when one connection is compromised.
Cover Service Pricing in Arlington
Cover service costs in Arlington depend on what we find. A panel gasket replacement runs $180 to $420 per joint. Mini-split replacement for an undersized unit lands between $3,800 and $7,200 depending on tonnage and line-set length. A full 100-amp to 200-amp panel upgrade runs $4,200 to $6,800 all-in with Arlington permitting. Foundation correction on a racked unit, including piers and re-leveling, starts around $8,000 and climbs with soil conditions and access. Every one of those prices is written down before we start, per Haven Standard Clause 1. No door-side upsells, no surprises at the end. Call (971) 497-2402 for a line-item quote specific to your lot.

FAQs - Cover ADU in Arlington
No. We’re an independent Cover service provider in Arlington. That means we can recommend the right fix without a factory sales target attached. We source structural parts from Cover’s licensed supply chain to protect your warranty, and we’re free to tell you when an aftermarket component is the smarter choice.
They hold up structurally, but their factory-specified HVAC often doesn’t. Arlington heat indexes regularly pass 105°F, and Cover’s original mini-split sizing assumes a milder climate. We frequently replace those units with higher-capacity systems. The glass-heavy envelope also needs proper air sealing at every module joint, or humidity finds its way inside during shoulder-season months. Call (971) 497-2402 if your unit can’t hold temperature in August.
Yes, but the parking requirement shapes which Cover model fits. Arlington requires covered parking on the same parcel for new accessory units, which differs from requirements for a New Detached ADU - Arlington project. The S Series, being narrower, leaves room for a carport where a C or M Series often doesn’t. We bring a parking plan to every first visit so the model choice doesn’t stall at plan check.
Most single-issue repairs, like a gasket replacement or a panel adjustment, finish in one day on site. Foundation correction and re-leveling takes three to five days because the concrete must cure before we reset the frame. Panel upgrades take one to two days plus the Arlington inspection schedule. We give you a written timeline with your written price.
Racked frame correction starts around $8,000 when it involves piers below grade and re-leveling of the steel base channels. The exact number depends on soil conditions on your lot and how far the frame has moved. Every quote is written before work starts. Call (971) 497-2402 for an exact figure.
