Installing your own carpeting is a job many do-it-yourself enthusiasts shy away from, but with the right tools it can done. Start by removing all of the old carpet or other flooring in the room you're renovating. Be sure that all of the old carpet pad is gone, as they are usually as worn as the carpet and should be replaced. once your subfloor is clean and you've repaired any creaks or weak spots, lay out your new tackless strips.
Tackless strips do have a few tacks, but they save you time because they hold the carpet and you won't need to go over the whole floor putting in individual takes. Lay them along the perimeter of the room, avoiding doorways, and be sure they fit tightly together in corners. Then roll out your strips of carpet, attaching them firmly to the tackless strips and joining their edges together with duct tape.
You are now ready to lay out your carpet pieces. Most rooms will require more than one piece, especially with the special shapes required to fit doorways properly. When cutting your pieces, remember to measure twice and use a piece of scrap plywood as a cutting board. Use seam tape, activated by a hot iron, to seal carpet seams together and a carpet roller to smooth out any excess.
You will need to rent a knee kicker and a carpet stretcher to finish your carpeting. The knee kicker grips the carpet and stretches it over the tackless strip, which is nearly impossible to do by hand. The carpet stretcher works the same way, but is longer and is used to attach the area between two finished sections of carpet. Then use a stair tool to tuck the edge of the carpet in at the wall, trim any extra pieces off, and attach a door edge strip. Your carpeting is now complete, and ready for your enjoyment.
