If you have damaged aluminum siding, it is possible to replace single panels. Aluminum siding installs with interlocking panels, which have lips shaped like a reverse "J", alternating at the top and bottom of pieces.
Aluminum siding is commonly chosen because of its durability, but it can fade, rust, and get damaged from weather or objects. Replace an aluminum siding section by following these steps.
Prepare to Replace the Aluminum Siding Section
To replace the aluminum siding section, gather:
- work gloves
- tape measure
- utility knife
- yellow tin snips
- siding removal tool
- scrap wood
- one-and-one-half inch galvanized finishing nails
- replacement siding
Attempt to locate a spare siding section left over from installation. Otherwise, contact the manufacturer for replacement pieces, or find a close match.
Remove the Damaged Piece
Start by checking for loose pieces of siding that are easier to remove. If you can't find loose sections, isolate a siding piece at the top to remove first. Insert the siding removal tool below the lip of the siding piece directly above the one you want to remove and wiggle it slightly. After the piece has loosened, separate the lower edge of the piece you want to remove from the good piece by hand.
Be careful not to bend the siding upward, or it may create creases in good siding. Set scrap wood below the upper piece to keep it in place while you remove nails.
Use the hammer and pry bar to remove nails, taking care to not push down on the siding, then remove the piece. Avoid removing sections by pulling on overlapping seams, which bends the good siding.
If you don't have a siding removal tool, score a vertical line on both sides of the panel with a utility knife two inches from the top. Use the tin yellow snips to cut the line, leaving the two inches at the top. Yellow tin snips are made for cutting straight lines.
Install the New Siding Piece
Measure the empty space and transfer the measurements to the new piece. Add three-fourths of an inch to each side, then cut the piece with tin snips or the knife. Be certain to cut with yellow tin snips that are made to cut straight lines.
Apply caulk to the edges of the remaining piece of damaged siding. Align the flanges on existing siding with the flange on the new piece, remove the wood, and hammer in the nails. Don't reuse nails from old siding.
Space nails according to manufacturer's suggestion, or nail them four inches apart, but not too tight to allow room for expansion, Use the siding tool to help you hook lips in place. Click here for more information on choosing a siding service.Share
