Temperature increases cause objects to expand…. like our house. In hot summer days, our houses stretch and creak, also causing those nice caulked lines to crack. If those seams are not caulked correctly, we allow moisture to seap in that could create problems in the future. The best way to avoid this is by using Sherwin Williams Elastomeric caulking. This caulking is designed to expand with the change in temperatures so you only caulk once! This was the tip of the day from your RC Painters, Colorado Springs.
