Attic Access Stairs

Click here to view a larger image.

Attic stairs provide easy access to additional storage space.
Problem: You have lots of storage space in your attic, but you aren't using it because you hate to drag out a ladder and squeeze through your access panel every time you want to put something up or take something out.

Solution: It's easy to gain access to your attic if you have attic stairs.

Equipment list:
 
measuring tape
drill, with assorted drill bits and a Phillips driver bit
crowbar
safety glasses
reciprocating saw
ratchet
miter box
hammer
circular saw
 
*  Your ceiling joists are placed either on 16" or 24" centers. Check the measurements before you purchase your attic stairs.
 
*  It's usually best to install attic stairs in place of an existing access panel. However, you can install them almost anywhere.
 
Install the stair assembly

  1. Remove the access panel, and pry off any trim pieces. Make sure the area between the joists is free of obstructions such as plumbing or electrical wiring.
  2. Remove any framing between the joists. Use the reciprocating saw with a flexible metal-cutting blade to cut through any nails holding the framing in place. You may need to pry the framing away from the joists to provide a gap for the blade.
  3. Mark the stair measurements onto the ceiling. Make sure the marks are between the joists.
  4. Cut along the lines with the reciprocating saw. Support the edges of the drywall as you cut; otherwise, the drywall could break and tear off. You may want to cut the drywall in small sections.
  5. Use drywall screws to fasten the edges of the stair opening to the ceiling joists.
  6. Install temporary 2"x4" support ledges on each end of the stair opening. The ledges will hold the stair assembly in place so that you can secure it in position.
  7. Install 2"x8" headers between the ceiling joists beside the stairs. The headers will help support the weight of the stairs.
  8. Tie the stair assembly together, and have someone help you to lift it into the attic and set it on the temporary ledges.

* For extra safety, drive screws through the stair frame into the joists. Drive the screws only part of the way into the joists; they will provide additional support while you adjust the position of the stairs.

  1. Use wooden shims to square the stairs and fill any gaps between the frame and the joists.

* The shims will remain in place and be trimmed flush later.

  1. Have an assistant lower the stair door without unfolding the stairs.
  2. Pre-drill pilot holes for lag screws, and then use a ratchet to screw the frame to the joists.
  3. Remove the temporary screws from the frame.

Cut the stairs to size

* Attic stairs are usually long enough to accommodate different ceiling heights. Most stairs will need to be trimmed for a custom fit.

  1. Unfold all but the bottom section of stairs.
  2. On the next-to-last section, measure the distance to the floor from both the front edge and the back edge.
  3. Unfold the last section, and transfer the measurements. Place the stairs on a stable surface, and cut them to size with a circular saw.

Finish the project

  1. Remove the temporary support ledges.
  2. Use finish nails to install trim around the edges of the stair opening. Miter the corners of the trim for a more professional look. Leave 1/4" clearance between the trim and the stair panel so that the stairs open easily.
  3. Set the nails, fill any nail holes, and apply touch-up paint if necessary.
