The crew wrapped the post bases with the same MortairVent rainscreen fabric that was used under wood shingles in the upper stories. The fabric creates an air space that promotes drying for the pre-primed shingles and extends the service life of the paint job.
Here, a course of shingles has been nailed on over the MortairVent and a plinth, or "shingle base cap," as the crew terms it, has been applied at mid height.
To help visually unify the home's front facade, the shingles on the porch post bases echo the shade of the shingles on the dormers above.
The location of the porch top was dictated by structural considerations. Here, the crew is experimenting with a trim solution for the upper termination of the columns, which was ultimately rejected in favor of an untrimmed column top.
With the columns wrapped and ready, Mark Pollard makes a layout mark for a railing at the center of the post.
Pollard holds a top sub-rail in place before marking it and cutting it to length. This piece will be used to build the baluster assembly and fasten it in place.
Pollard measures the distance from post to post in order to determine where mark the center of the opening on the ralis for his baluster layout.
Pollard makes a layout mark at the center of the top rail (left) and transfers the mark onto the bottom rail (right).
Pollard transfers layout marks from a template onto the porch railing, establishing a three-and-three-quarter-inch space between balusters as required by code.
Pollard works his way along the bottom rail, setting a screw through the pre-drilled hole into the end of each baluster.
Pollard pins the top ends of the balusters to the sub-top-rail with three 15-gauge stainless steel nails.
Pollard pre-sets stainless steel #7 1.5-inch screws into the sub-top-rail in preparation for attaching the baluster and rail assembly to the already placed top rail.
Pollard pre-sets #8 three-inch screws in the bottom rail as he gets ready to install the baluster and rail section between the porch columns.
Pollard shims the lower rail and baluster assembly up tight against the already-positioned upper rail.
Screwing from below, Pollard fastens the railing assembly through the sub-top-rail into the upper railing using his pre-placed stainless steel #7 1.5-inch screws.
Pollard screws up into the top rail through the sub-top-rail to fasten the baluster assembly in place.
