Installing or changing a windowsill or lintel involves several steps to ensure a secure and aesthetically pleasing outcome. First, the existing windowsill or lintel is carefully removed, taking care not to damage the surrounding structure. The new windowsill/lintel is then measured and cut to fit precisely. After fitting, it is securely attached, often using screws or appropriate adhesive. Sealant is applied to prevent water infiltration and promote longevity. The final step involves finishing touches, ensuring the new windowsill/lintel blends seamlessly with the overall aesthetic. This process, when executed with precision, enhances the functionality and visual appeal of the window or opening while addressing any structural concerns.
