How to build porch stairs
The first step of the project is to attach the ledger board to the wooden posts, as in the image. Cut the 2×10 piece of lumber at the right size and lock it to the posts with carriage bolts. Lock the ledger to the posts with clamps, drill pilot holes and insert the carriage bolts into place. Use a spirit level to make sure the ledger is perfectly horizontal.
The next step is to build the four stringers for the stairs. As you can see in the plans, you need to use a piece of 2×12 lumber and a carpentry square to mark the cut lines. Make the notches in the slats with a good circular saw. Clean the cuts with a sanding block.
In order to get the job done in a professional manner, we recommend you to set the 4×4 posts for the railing into concrete. Dig 3′ deep holes, set the posts, plumb them with a spirit level and fill the tube forms with concrete. In addition, we recommend you to build a small concrete landing pad, as to protect the stringers from moisture. Lock the stringers to the ledger and to the landing pad with metal hardware and appropriate screws.
Afterwards, you need to attach the 2×6 risers to the stringers, as in the image. Drill several pilot holes and lock the components into place with 2 1/2″ galvanized screws. Make sure both ends of the risers are flush with the stringers, before locking them into place.
Installing the 2×6 treads into place is a straight forward job, as you just need to cut them to size with a circular saw and attach them to the stairs frame. Make sure you place a nail between the slats, to drain the water in a professional manner. Smooth the exposed edges with a router or a sanding block. Cut notches in the treads, as to fit around the 4×4 posts.
Last but not least, we recommend you to take care of the finishing touches. Fill the holes with wood filler and let it to dry out for several hours. Afterwards, smooth the wooden surface with fine-grit sandpaper and vacuum the residues. Take a look on the rest of the project is you want to learn how to build the railing and the frame of the porch.
Smart tip: Apply several coats of stain or paint to the wooden components, if you want to protect them from decay and to enhance the look of the porch stairs.
