Why Cover Plates Matter

Cover plates serve both functional and aesthetic purposes in your finished attic. Functionally, they protect you from accidental contact with electrical terminals and prevent debris from entering electrical boxes. Aesthetically, they provide a clean, finished appearance that shows attention to detail. Building codes require cover plates on all outlets, switches, and junction boxes. While this is a simple task, taking time to choose the right style and install them correctly makes a noticeable difference in the overall quality of your finished space.

Step-by-Step Guide

1

Count and Purchase Cover Plates

Inventory all devices and purchase matching plates:

  • Count standard duplex outlets (2-plug receptacles)
  • Count single-pole light switches
  • Note any combo boxes (switch + outlet, double switches)
  • Count GFCI outlets, USB outlets, or decorator-style devices
  • Identify data, cable TV, or phone jack locations
  • Buy a few extras in case of breakage or future changes
2

Turn Off Power and Verify

Take safety precautions before working:

  • Turn off circuit breakers for the attic electrical circuits
  • Use voltage tester to confirm power is off at each device
  • This is especially important if you need to adjust device positioning

Note: If all devices are already properly positioned and you're only adding cover plates, power can remain on - but turning it off is always the safest approach.

3

Adjust Device Positioning

Ensure outlets and switches are properly aligned:

  • Devices should be flush with or slightly recessed from wall surface
  • Loosen mounting screws slightly to allow adjustment
  • Ensure device is straight (parallel to wall edges)
  • Use device ears to space properly from drywall
  • Retighten mounting screws securely but don't overtighten
4

Install Cover Plates

Attach cover plates with care:

  • Position cover plate over device, aligning screw holes
  • Insert screws and hand-tighten first
  • Use screwdriver to snug - don't overtighten or plate will crack
  • Align screw slots vertically for professional appearance
  • For screwless plates: attach base plate first, snap on cover

Pro Tip: If using plastic plates, consider getting a few extras. They can crack if overtightened. Screwless plates cost more but look much cleaner.

5

Test and Inspect

Verify everything works correctly:

  • Turn power back on at the breaker panel
  • Test each outlet with a plug-in tester or lamp
  • Test each switch to confirm it operates correct fixture
  • Test GFCI outlets with the test/reset buttons
  • Visually inspect all plates for proper alignment and fit

Pro Tips

  • Match plate finishes to door hardware and light fixtures for cohesive design
  • Screwless plates are worth the extra cost for a cleaner, modern look
  • Use painter's tape on screwdriver tips to avoid scratching metal plates
  • Keep screws in a magnetic bowl while working to avoid losing them
  • Align all screw slots the same direction (vertical is traditional)

Frequently Asked Questions

What type of outlet covers should I choose?

Standard plastic plates work well and are most affordable ($1-3 each). Screwless plates have a cleaner, modern look ($4-8 each). Metal plates (stainless steel, brass) add durability and style ($5-15 each). Match the finish to your door hardware and light fixtures for a cohesive look. White is standard and works in most spaces; consider colors or metal finishes for design-focused rooms.

Do I need to turn off power to install cover plates?

Yes, always turn off power before installing or adjusting cover plates. While cover plate installation itself doesn't involve touching wires, you may need to adjust the outlet or switch positioning, which could cause accidental contact with live terminals. It's a simple safety precaution that takes only a moment.

My outlet doesn't sit flush with the wall. How do I fix this?

Outlets should be mounted so they're flush with or slightly recessed from the wall surface. If the outlet protrudes, loosen the mounting screws and push it in before retightening. If it's recessed too deep (more than 1/4 inch), you can use an electrical box extender or spacer ring. Gaps larger than 1/8 inch between the device and cover plate indicate the box may not be properly installed.

Should cover plate screws be vertical or horizontal?

Traditionally, cover plate screws are installed with the slots aligned vertically, which is the professional standard. This creates a clean, uniform appearance throughout the house. Some prefer horizontal alignment, but consistency is most important. Screwless plates eliminate this consideration entirely for a seamless look.
