Condensation on the inside of your windows means humidity levels are too high in your home. Attracted to cooler surfaces, such as windows or thin, outer wall, the combination of air and water vapor creates that "sweat" you notice on windows during cold weather. The cooler the air is, the less moisture it can hold, which is also why you sometimes see condensation on windows if you have your air conditioning on high and your home's interior temperature is below 60 degrees.

Although minimal humidity is essential for comfort and health, excessive and continuous condensation may cause expensive damage to your home, such as paint peeling, decay and development of dangerous mold. In extreme cases, condensation may even promote structural damage.

Allowing high humidity levels to exist in your home invites rapid growth of mildew, mold and bacteria that thrive on warmth and moisture. Insects such as cockroaches, termites, fleas, dust mites and moths also flourish in these conditions, contributing to health problems, home damage and a tenacious infestation that could require the services of a pest control company.

Investing in replacement windows and window insulation to prevent condensation can help:

  • Reduce symptoms of rheumatism and arthritis
  • Reduce asthma attacks exacerbated by dust mites
  • Reduce allergy symptoms caused by mold spores
  • Eliminate irreparable damage to furniture, clothes and walls due to mildew
  • Eliminate moldy, musty smells that could aggravate respiratory conditions
  • Reduce sweating and continual perspiration, a common cause of rashes and dermatitis


Solutions to Sweaty Windows

Discount vinyl replacement windowsReplacing single-pane glass windows with double-paned glass windows enhanced by argon gas filling and low-e coating will significantly reduce condensation on ill-fitting or drafty windows. Double-pane window insulation helps regulate relative indoor humidity by keeping it around 35 percent, enough to prevent condensation from accumulating on windows.

Homeowners dealing with window condensation problems might also consider installing double-paned, sliding doors made with glass that has been coated with a substance capable of separating light and heat energy. By reflecting heat back to its source (the sun) and allowing light to pass into the home, condensation is effectively reduced. In addition, you will save on daytime lighting costs by enhancing your home's brightness with insulated sliding glass doors.

Some replacement windows are equipped with "warm edge" technology that reduces conduction around the edge of an insulated glass unit. By keeping window edges warm, the chance of condensation forming is minimal to none.


Replacing Drafty Windows to Reduce Condensation and Lower Energy Bills

Conserving energy within the home means paying lower heating and cooling bills as well as feeling comfortable in a consistently temperate environment. Many homeowners do not realize how much leaky windows and condensation cost them even if the leak is negligible. In fact, government research into how much ill-fitting windows cost a homeowner in annual energy bills found that homeowners can potentially save nearly 20 percent on energy bills each month by repairing or replacing windows that allow heat or cold to escape through bad seals, rotting frames or windows that were unprofessionally installed.
