Aluminum Siding Repair

Some of the primary benefits of having aluminum siding installed on your home are that this material is strong, durable, and virtually maintenance free. However, even the best of the best can become damaged. For instance, aluminum siding can become dented. If a baseball were to hit it hard enough or perhaps the home struck by hail, you would likely experience some type of damage. The good news is that aluminum siding can usually be repaired.


You will find that when aluminum siding becomes damaged fixing it is pretty much pain free. For example, if you find a dent in your siding, you could start by drilling a couple of one/eighth inch holes inside the large dent. Then, place a flat washer onto a sheet metal screw, screwing it partially into one of the drilled holes. Now, using pliers, pull the screw, which will help pop the dent out. Once you have the dent out, take two parts of body filler to fill in any leftover dent and drill holes. The screw is removed, and then filler applied, and once dry, sanded down. The final step is to paint over the area where the dent was found.

Another option for repairing a damaged section of aluminum siding is to take a utility knife, cutting the top and sides of a rectangle around the area. Next, cut a patch of matching aluminum foil, making sure the new piece is three inches wider than the damaged spot. Keep in mind that you want the top portion of the patch to push a minimum of one-quarter inch under the piece located above. This way, the bottom section will slide easily into place.

When done, the surfaces should be cleaned off so they can be glued. The patch you just inserted would then be applied with clear silicone sealant to the back. Pressing this patch of aluminum siding in place for about 30 seconds will help it adhere. You then can use a damp cloth to wipe off any excessive sealant that might have seeped out of the sides. The result is repaired siding that is difficult to see.

Corner Caps

Sometimes, corner caps are also damaged. To correct this problem, the damaged caps would be removed, as well as nails with a small crowbar. For the next step, work at the lowest section, simply sliding replacement corner caps into place, making sure they fit snugly under the bottom lip. Then with aluminum nails, secure them in place. After this step is complete, the nailing strip would be cut off the top cap, followed by the application of a clear, silicone sealant to the backside. Finally, the cap would be slipped underneath the outside strip, and pressed into place for approximately 30 seconds to help the cap adhere.
