As a home owner, you want to keep your residence in good repair. Despite your best efforts, exterior siding panels on homes can crack, rot, or sustain water damage from cold and wet weather. If you have damaged siding panels, you can easily remove and replace individual panels or sections of panels. Here is the procedure to remove and replace damaged siding made of the most common siding materials:

Wood Siding:  With a utility knife, cut through any caulk joints where the ends of the wood siding panels join upright posts. Next, remove all rotted or damaged wood panels by prying them away from the building. If you have small areas of damage that do not involve an entire panel, cut them away with a circular saw. Check for wood rot or termite damage under the removed panels and repair or replace the damaged substructure as needed. Measure and cut new wood panels to the exact lengths that you need. Prepare the new panels by priming the back of each with an oil-based primer. Install 1" x 4" strips of treated lumber where the new siding will be placed. These strips are used to hold the bottom edge of the siding panels away from the building. Slide the first panel into position and use a hammer to pound it underneath the bottom edge of the panel above it. Screw the panel in place by drilling through the bottom of the panel into one of the 1" x 4" lumber strips. After installation, prime and paint the new panels with acrylic exterior house paint.

Vinyl Siding:  Use a metal scribe to outline the damage on a vinyl siding panel. Use a zip tool (a tool to lift the edges of vinyl siding) to pry the damaged panel away from adjacent panels. With tin snips, cut out the damaged portion of the panel. This will expose a metal strip where the panel was secured to the building. Cut a new piece of vinyl siding that is a few inches longer than the damaged original. Cover the back of the new panel with vinyl siding adhesive and hang it on the metal strip to secure it to the building. Allow the edges of the new panel to overlap the siding panels on each side. Secure the new panel in place with stainless steel screws.

Fiber Cement Siding:  Use a pry bar to loosen a damaged panel of fiber cement siding. Remove the panel by prying it away from the panel above it. Remove any nails that remain on the panel above the removed panel. Run a screw driver underneath the bottom edge of the panel above to make sure that all nails have been removed and you have a clear path to insert a new siding panel. Cut a new panel of fiber cement siding to fit the exact length of the removed panel. Slide the top of the new panel under the panel directly above it. Blind nail the panel on the top edge by angling stainless steel nails into the panel and the building substrate. Paint the new panels with acrylic exterior house paint.   

Inspect the exterior siding on your residence often to spot any new damage before it can become a problem. With consistent inspections and new siding panels installed, you can keep your residence looking good for many years.
