To fix proud drywall and tight fits around a box extension, start by turning off power and removing the cover plate. Detach the electrical box and install the extension carefully, ensuring it’s flush with the drywall surface. Use drywall shims or trim as needed to fill gaps for a smooth finish. Tighten all components securely, then reattach the cover and restore power. Continuing will guide you through precise steps for a safe, professional-looking result.
Key Takeaways
- Use a box extension to increase box depth, reducing drywall bulges and creating a flush surface.
- Select an extension matching your existing box size and drywall opening for a proper fit.
- Turn off the power, remove the cover, and detach the box before installing the extension.
- Securely attach the extension, ensuring it doesn’t interfere with wiring or drywall integrity.
- Reinstall the cover, restore power, and verify a flush, safe, and compliant electrical setup.

Have you ever wished you could expand the storage or functionality of your existing boxes? Whether you’re installing new outlets, switches, or adding extra circuits, sometimes the current box just isn’t enough. That’s where box extensions come into play. They allow you to fix proud drywall openings or tight fits, providing a seamless way to increase space without tearing into walls. When working with electrical boxes, it’s essential to follow electrical codes to ensure safety and compliance. This means choosing the right extension size and type, and making sure everything fits securely and correctly. It’s also important to have the proper installation tools handy—like screwdrivers, pliers, and possibly a drywall saw—to make the process smooth and efficient.
Using box extensions is straightforward, but attention to detail is key. First, turn off the power to the circuit you’re working on to prevent any accidents. Remove the existing cover plate and carefully detach the box from its mounting. If the box is protruding too much or the drywall opening is larger than needed, you can install an extension that fits snugly onto the existing box. These extensions are designed to align with electrical codes, ensuring they provide enough space for wires and allow proper ventilation. Make sure to choose an extension made from durable materials, usually plastic or metal, that match your existing box for a clean finish.
When installing the extension, use appropriate installation tools to secure it firmly. Screws should be tightened enough to prevent movement but not so tight that they crack the extension or damage the drywall. As you work, double-check that the extension doesn’t interfere with other components or create a bulge in the drywall. If needed, you can trim the drywall opening or use additional drywall repair techniques for a flush fit. Remember, all wiring must be kept within the box and extension, without overfilling, to stay within electrical code limits. Overcrowding can lead to overheating and is a serious safety concern. Additionally, understanding box size and capacity helps ensure the extension will accommodate the wiring safely and meet code requirements.
Once the extension is securely in place, reattach the cover plate and restore power. Testing your work confirms that everything functions properly and looks professional. Using box extensions is an effective way to fix proud drywall and tight fits, making your electrical setup safer and more functional. Always prioritize safety and adhere to electrical codes throughout the process. With the right tools and a careful approach, expanding your electrical boxes becomes a simple task that enhances both safety and aesthetics.
