How To Extend A Deck
What You’ll Need
First, use a tape measure to determine how much extra space you want to add to your existing deck flooring. Once you have that measurement, add 6 inches to allow for an overhang on each end of the extension. For example, if you want your extension to be 10 feet long, you will need 12 feet of lumber.
Next, using either 4”x4”s or 6”x6”s for support posts, nail or screw them into the ground at each end of the desired extension. Make sure that they are level as you work. Then, attach your 2”x8” or 2”x10” joists to the support posts using nails or screws. Predrill holes for the screws to avoid splitting the wood. Start in the middle and work your way out so that the joists are evenly spaced.
Once the joists are attached, lay your flooring boards perpendicular to the joists. Start at one end and work your way down, attaching each deck board with either nails or screws. Be sure to predrill holes for the screws again. Do not attach the composite decking flooring all the way to the end of the joists yet – this will be done later.
Now it’s time for railing! If your deck already has railing, simply unscrew the top rails and reattach them at the appropriate height on your new extension. If you need to install a new railing, begin by attaching stair stringers at each end of your extension using lag bolts and washers. The stringers should be placed at least 16 inches apart but no more than 24 inches apart.
Once the stringers are in place, screw top and bottom rails into them using 3-inch screws. Finally, attach balusters by screwing them into both the top and bottom rails using 2-inch screws spaced no more than 4 inches apart. Now you’ll have a deck extension that is perfect for family gatherings.
