Attach Stringers

Step 1: Select Site, Set Posts

Select the site for the pergola and mark the placement of the four posts. Use a post-hole digger or two-person auger to dig holes to a depth of 24" and width of 9". Add a few inches of gravel to the bottom of the holes for drainage. Insert 4" x 4" posts in holes. Ensure the posts are level and plumb. Attach temporary 2" x 4" bracing to hold in place. Mix fast-drying cement according to manufacturer's directions and pour in holes. Let cure for 24 hours.

Step 2: Attach Joist Beams

Cut joist beams from 2" x 10" boards to span the pergola posts. To create a decorative look on the end of the joist beams, draw a straight or curved design on the wood and cut along the line with a jigsaw. Temporarily clamp in place while holes are drilled through the beams and posts. Attach the beams to the posts using 3" lag bolts.

Step 3: Attach Stringers

Cut the stringers from 2" x 6" boards to span and overhang the joist beams. To create a decorative look on the end of the stringers, draw a straight or curved design on the wood and cut along the line with a jigsaw. Evenly space the stringers perpendicular to the beams and toenail in place using 3" galvanized deck screws.
