This meticulous application not only enhances the window’s performance but also contributes to the longevity of the installation. Homeowners in Plano, TX, will appreciate the added protection against the elements, safeguarding their homes for years to come.
Next, smoothing out the sealant with a tool or finger ensures an even, tight seal around the window. This step is vital for achieving a professional-looking finish that complements the home’s aesthetics.
