Whether or not storm windows are a good investment for your home depends on the windows that you currently have. If your home has high quality Energy Star certified windows that are well insulated, you will not benefit from a storm window like you would with poorer quality or older windows.

Storm windows are an option worth considering if you are looking for a way to improve the insulation of your home. They will help cut down on heating and cooling expenses throughout the year, but can be somewhat of a hassle if you like opening and closing your windows. It is important to consider both interior and exterior storm windows and replacement windows before deciding on what is right for your home.

Storm Window Maintenance

Even though a storm window will save you money compared to totally replacing the windows, they require more maintenance if you like to open and close the windows during the warmer months. You will have to remove the storm windows and reinstall them each year in order to retain the function of your standard windows. This can be a lot of work if you are using storm windows on a second story home.

Storm Window Condensation

One issue to be aware of before installing storm windows 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 can rot away over time.

To prevent damage from condensation, it is vital to ensure that the standard window is sealed properly before the storm window is put into place. Use caulk on the sides and top of the window to seal any possible holes.

Your local contractor will also be able to guide you on the best way to upkeep your new storm windows, prevent damage, and extend their lifespan.
