One of the most significant benefits of window caulking is its ability to improve energy efficiency. Over time, gaps and cracks around windows can develop due to settling of the home, weathering, or the natural wear and tear of materials. These gaps allow warm or cool air to escape, making it harder for your heating or cooling system to maintain the desired indoor temperature kettle contracting. By sealing these gaps with caulk, you can prevent air leakage, reduce drafts, and minimize the load on your HVAC system. This, in turn, can help lower energy bills and make your home more comfortable throughout the year.
