The old, rusty and disintegrated weather seal has been removed from the bottom of this old wooden sliding patio door along with the rollers to be replaced.

Tiny nail holes are drilled about every ten inches along one leg of two lengths of 1/16″ x 3/8″ x 3/8″ aluminum L stock.

The other leg of each length is wiped clean with Acetone.

Self-adhesive fiber weather-stripping is added to the newly cleaned surface.

Using small brads, the first length is nailed along the bottom edge.

And, then the final length is installed the same way along the top edge.

You now have a door that will no longer be drafty.
