Many people are unaware that, over time, dirt and debris can accumulate in window frames and sills. When it rains, this buildup is often washed onto the glass, leaving windows dirty again shortly after being cleaned. As the accumulation grows, it becomes more difficult to maintain clean windows and can even affect indoor air quality, potentially impacting health. If left unaddressed, the buildup can begin to eat away at the sills, causing rot, corrosion, or structural damage, which may require extensive repairs. It can also lead to long-term damage to the window components, resulting in costly replacements. Regular professional cleaning not only preserves the appearance of your windows but also protects their structural integrity and helps maintain a healthier indoor environment.
