Price of irregularly shaped electrical distribution box cover

Material and Cover Options

Standard metal or plastic electrical box covers for indoor or outdoor use generally range from $20 to $50 for pre-made sizes and shapes, including square, rectangular, and round boxes. For irregularly shaped boxes, custom metal covers may be required, which can increase costs to $100–$200 or more depending on the complexity, thickness, and corrosion resistance. Weatherproof or outdoor-rated covers carry a premium due to additional sealing and durability requirements.

Typical labor for installing a standard cover ranges from $50 to $150, while complex or custom installations may add $100–$300 to the total cost. For full panel replacements or upgrades, total costs including labor and permits can reach $1,200–$6,000, but this includes the panel itself, not just the cover.
