This often involves loosening and removing existing fasteners, taking care not to damage the surrounding siding. Once the damaged corner is removed, the area should be thoroughly cleaned of any debris, dirt, or loose paint. This clean surface ensures optimal adhesion for the new corner piece and sealant. The new corner should then be positioned precisely against the adjacent siding panels, ensuring a perfect alignment. This precise alignment is crucial for a seamless and visually appealing finish.
Securing the Replacement Corner
Securing the replacement corner piece involves using appropriate fasteners, typically self-tapping screws designed for aluminum siding. These screws should be spaced evenly along the length of the corner, approximately every 6-8 inches, depending on the size and type of corner piece and the manufacturer’s recommendations. It is crucial to avoid over-tightening the screws, which can damage the aluminum and compromise the integrity of the corner. The screws should be driven in firmly, but not to the point of stripping the screw head or causing the aluminum to dent or buckle. The goal is to create a secure and firm attachment without causing any damage.
Ensuring a Weather-Tight Seal
After the corner piece is securely fastened, a weather-resistant sealant should be applied to further enhance the weatherproofing. This sealant should be compatible with aluminum siding and applied along all seams and joints where the corner piece meets the existing siding. This creates a barrier against moisture, preventing water infiltration and potential damage to the underlying structure. A high-quality, paintable sealant is recommended to allow for easy matching with the existing siding color. The sealant should be applied neatly and evenly, ensuring complete coverage of all exposed edges and joints.
Final Installation Appearance
The final installation should exhibit a seamless integration of the replacement corner with the existing siding. The new corner should be flush with the adjacent siding panels, with no gaps or misalignments visible. The fasteners should be evenly spaced and countersunk slightly below the surface of the aluminum, preventing them from becoming snagging points or potential sources of water penetration. The sealant should be neatly applied, without any visible excess or runs. The overall appearance should be one of clean lines, consistent color, and a professional finish. A well-installed corner piece will be virtually indistinguishable from the original siding, restoring the aesthetic integrity of the home’s exterior. The entire repair should appear as if the original corner piece was never damaged.
