Storm Window Condensation

One issue to be concerned about when having a storm window installed in your home is condensation between the storm windows and your standard home windows. If condensation is allowed to build up between these two layers, all of the trim and exterior wood on the home will rot away over time. To prevent this from occurring it is vital to ensure that the standard window is sealed properly before the storm window is ever put in place. Use caulk on the sides and top of the window to seal any possible holes. This will help keep condensation out after installation.
