1. First, determine how much hardwood you'll need for your particular area. Figure the square footage, then add 15-20% more to allow for damaged wood and installation problems. Then select the installation method: nail-down, glue-down or floating. Because the room in the this example has a sub-floor, the crew nailed the hardwood directly to the floor.
2. When the wood arrives, open the packages and let the wood acclimate to the temperature and humidity of the area in which you plan to install. The wood will expand and contract according to the moisture (or lack of moisture) in the air, so a few days of acclimation will allow for maximum contraction/expansion of the wood.
3. Next, weed out any discolored, damaged or broken pieces and be sure to check the tongue and groove areas to make sure they aren't damaged or irregular (preventing them from joining properly).
4. Remove old carpet and inspect the floor underneath. (The DeWittes had carpet with sub-floor underneath.) The sub-floor should always be level, flat and in good condition. If water damage is present, replace with clean, dry plywood. To remedy squeaks, screw a long drywall screw into the sub-floor and into the joist below.
5. If available, use a miter saw to cut the flooring to quickly produce a clean cut.
6. Begin the installation. Start at the end wall and move outward across the room. Position the groove edge flush against the wall, then move out to create a 1/2" expansion gap.
7. Set the new floorboard in place with the groove set into the tongue of the existing board (figure A). Use a rubber mallet to tap the board snugly in place. To secure, use a nail gun to nail through the tongue of the new board at a 45-degree angle, directly into the sub-floor at approximately 12" intervals.8. When you have moved about two rows away from the wall, use a flooring nail gun to secure the boards (figure B).
9. Continue moving along, staggering the lengths of the boards and installing securely. Cut the last board to fit the space as close to the wall as possible. To install under a door jamb, simply measure the thickness and mark on the jamb. Use a saw, followed by a chisel, to remove that portion of the doorjamb that will allow the hardwood to be installed underneath (about 1/16" - 1/8").
10. Once finished, follow manufacturer's directions for the care and maintenance of your particular hardwood flooring.
