Deck repair is something that many homeowners have to face from time to time. There are a myriad of issues that will arise over the life of the deck which can include anything from popped nails to rotting posts. A common problem that happens to a deck that is not properly weather treated, maintained or sees a lot of hard weather conditions is that the floorboards begin to warp and bow. A bowed floorboard is one that is no longer straight in one way or another. The following article will show you how to spot and replace warped floorboards.

Step 1 - Spotting a Warped Board

If you can see that a board is warped then it took too long to get to replacing it. Boards that are terribly warped will be very noticeable because it will most likely be popping nails and have an extreme curvature of some kind. Not every warped board will be easy to spot. In order to find a warped piece of wood you must get eye level with it. You will be able to spot a warped board fairly easily as the ends will not lay flat or the centers will be slightly raised higher than the other boards. Use your level to be sure of warping.

Step 2 - Removing the Warped Board

Unless the nails are visibly popping out you will need to apply force in order to remove the boards. Pick an end to start with and insert the pry bar between the warped board and its neighbor. Push down and the board that is warped will pop off of the cross beams of the wooden deck. Move to the other side of the board in question; lodge the pry bar between it and the neighbor and then push down to dislodge it from the deck. With both ends removed you can insert the pry bar between the board you are removing and its neighbor based on where the nails are in the boards. When the board is completely loose you can simply remove it from the deck.

Step 3 - Putting in a new Board

Measure one of the boards that is not warped and go to a home improvement store or lumberyard and purchase a plank of wood and have them cut it to match the old board. When you get the lumber home, slide it in place and make it even with the other boards. Nail the board in place using galvanized nails as they are coated in zinc which protects the nail from the elements. Put two nails into each section at the crossbeams. When the nails are in place you can use the nail set to drive the nails below the surface of the board. Line the screws up with each nail so they are just next to each other. Use the screwdriver to drive the screws in place so that the head of the screw is over the head of the nail.
