Steps for Installing an Attic Ladder

And most importantly ... don’t forget the new attic ladder itself!

Step 1: Mark the Access Point

After you gather your tools and ladder, you’ll first need to mark up where you want the ladder to go. Choose a spot that has enough clearance so you can open the ladder fully without bumping into a wall or door. Also, think about where the access point is in the attic. Ideally, you’ll want a space where you can stand up all the way and not bump your head.

Finally, you’ll need to consider other obstacles, like plumbing, electrical wiring, or air ducts.

Once you’ve found the ideal location, measure out the dimensions using the tape measure and carpenter’s square, and draw a line using chalk or pencil.

Step 3: Assemble the Header

The header is what the ladder attaches to, so it needs to be secured to the attic. Create two 2" x 6" header boards and attach them to the top of the opening in the attic with the nail gun. You can nail into nearby ceiling joists for better support.

Step 4: Add Support Boards

Support boards help during the installation process while you’re lifting the ladder into place. Use one 1" x 4" piece of wood at each end of the opening, leaving a small ¼" lip for the ladder to sit on. Again, you can just nail these up through the drywall.

Step 5: Lift and Shim the Ladder Assembly

Now it’s time to lift the ladder into place on the support boards. This is a two-person job, as you’ll need someone in the attic to lift the ladder, as well as someone on the ground to assist. You’ll want to lift the ladder so the hinged end is resting on the ledge you created in the last step. When you’re ready, extend the hinge, but don’t pull the ladder down yet.

With everything in its place, check to make sure it’s level, then add in shims between the frame and the joists.

Step 7: Adjust the Ladder Length

Now it’s time to make sure your ladder is level. You may need to trim the legs of your ladder so they sit perfectly on your floor. Release the ladder to the floor and see if it extends all the way. The feet should be flush with the floor, and the metal hinges at the top shouldn’t have any gaps. If you have gaps, trim the legs with your saw until the ladder is at the right angle.

Step 8: Install the Feet

The last step is to install the ladder feet. These should slide easily over the rail, and you’ll want to secure them in place using bolts. Double-check again that the ladder fits the floor with the feet on, and you’re good to go.
