Phillips driving bit
Remove an old sliding door from your vinyl siding home and replace it with a new one.
Patio doors in a vinyl siding home are not mounted to the siding but to the wood beneath the siding, which makes door removal similar no matter what type of siding your home has. The old patio door's weight makes it necessary for two people to work together on this project. However, neither person needs to have any special construction knowledge to successfully remove the door. This should take only a few hours.

Slide a small crowbar between the sliding door's molding and the wall. Work the molding off the interior wall and set it aside. If you get the molding off without damaging it, you can reuse it around your new sliding patio door. Remove any exterior door trim in the same way. Be careful not to apply too much pressure to the vinyl siding as you pry the exterior molding off because it can crack.
Close the sliding doors while you stand on the door's interior side. Slide the screen door down slightly and hold it firmly with one hand on each side. Lift the screen door and pull the bottom out toward you. Lower the screen door to free the top edge from the top track. Set the screen door aside.
Remove the screws on the glass sliding door's top and bottom edge, using a Phillips screwdriver. Slide the door down slightly and hold it with one hand on each side. Lift the glass door and pull the bottom toward you. Lower the door from the top track and set the door aside.
Look around the fixed glass section's perimeter for all the screws securing it in place. Use a Phillips screwdriver to remove all the screws. Slide the glass section down slightly and remove it the same way you removed the door in Step 3.
Use a drill and Phillips driving bit to back out all the screws that secure the sliding door frame to the rough opening. You may notice some nails holding the door in place as well. Insert a reciprocating saw's blade between the sliding door frame and the rough opening. Turn the saw on and run the blade down each side and along the top to cut through all the nails.
Cut through the caulk bead running along the gap between the door frame and the vinyl siding, using a utility knife.
Tap the door frame's top two corners with a hammer to begin removing it from the rough opening. Pull the entire frame out of the opening.
