removing railing
After cutting the end post flush with the deck using a reciprocating saw, remove the old railing in sections.
Step 4: Redoing a Railing

Because the original railing on their deck was in such bad shape, the Johnsons decided to replace it with a maintenance-free railing system. They chose Fiberon, a vinyl-coated wood-plastic composite that costs about $70 per 6-ft. section. It's available in premade panels or as kits. The Johnsons liked the contrast the white railing offered.

For an existing deck or concrete slab, Fiberon makes a surface-mount bracket, as shown below. For new decks, the manufacturer recommends installing the posts before the decking and using metal brackets that attach to the joists. To conceal any minor gaps where the balusters meet the bottom rail, Graf recommends using a mildew-resistant acrylic caulk.

installation of post
The hollow post in this system slides onto the 12-in.-high aluminum base. Shim the bottom of the base as necessary so the post is plumb.

After you attach the bottom rail and insert the composite 2x2s into their precut mortises, wiggle the balusters into the top handrail. Instead of using toenails, the Fiberon rail attaches to the post with self-locking flanges for a fastener-free finish.
