Repairing a Deck

Project Overview

Repairing a Deck

Repair and maintenance needs for a well-built deck less than 10-15 years old are few. They usually involve resetting some fasteners, replacing a few pieces of decking, cleaning the deck to remove dirt and mildew, or reapplying finish. An older deck, especially one included in a home purchase, may have more problems. Moisture damage or rot in deck framing indicates that it is time for a new deck. One deteriorating joist or post usually indicates that more will soon follow.

Step 1

PULL POPPED NAILS

Remove loose or popped nails with a cat's paw or pry bar. Protect the board surface with a wide putty knife. Drive long deck screws in place of the nails. Drill pilot holes and use additional screws if necessary.

Step 2

REMOVE DAMAGED DECKING

Drive the claws of the cat's paw underneath nailheads to pry them out when removing damaged decking. Use a pry bar to lift out damaged boards.

Replace boards

Step 3

Replace boards

Protect adjacent boards with a wide putty knife. Cut and install replacement boards. Let a new board overhang at the edge of a deck; it's quicker and more accurate to trim in place than to trim before installing.
