A Simple Guide to Weatherproofing Windows for Ultimate Comfort

Did you know the average American pays $2000 for home energy costs per year? On average, more than half of a household’s annual energy consumption comes from two end uses: heating and air conditioning. Depending on the time of year, when heat or cold air escapes your home, you are losing money.

Weatherproofing windows is an effective way to reduce costs associated with your attempts to keep cold out of your home.

In this comprehensive guide, you’ll learn:

• Signs your windows need weatherproofing (from leaks to unmanageable utility bills)
• The best ways to weatherproof windows and get optimal results
• DIY weatherproofing methods
• When to call in the pros for a permanent solution

Signs Your Windows Need Weatherproofing

The main goal of weatherproofing windows is to keep outdoor elements like wind, rain, and cold air out while trapping indoor warmth during colder months. This involves sealing gaps and cracks around window frames to prevent drafts and energy loss.

Here are some telltale signs that it’s time to seal those gaps and keep your home comfortable:

• Drafts: If you feel a slight breeze near closed windows, even on a calm day, you likely have drafty windows. This is usually due to air leakage through cracks in the window frame or poor caulking. Drafts can lead to significant heat loss during the colder months and force your heating system to work harder, increasing energy costs.
• Visible Gaps or Cracks: Inspect the window frame for cracks in the caulking or gaps around the edges. Over time, weather conditions can cause caulk to crack or deteriorate, allowing air and moisture to seep through. Use a caulking gun to fill these cracks with fresh caulk or sealant foam to create a tight seal.
• Condensation or Frost: Are you noticing foggy or frosty windows? This often indicates seal failure or poor insulation. Double-pane windows should maintain an airtight seal to trap an insulating layer of air or gas between the glass panes. Condensation inside the window points to broken seals and gaps that let in water, risking mold growth and damage.
• Increased Energy Bills: Have your energy costs been rising unexpectedly? Inefficient windows could be the culprit. Poorly sealed doors and windows cause heat transfer, forcing your air conditioner and heating units to run longer to maintain a comfortable indoor temperature. 

How to Weatherproof Windows: DIY Methods

Ready to keep those drafts out and your energy bills in check? Here are some simple DIY weatherproofing methods to get your windows ready for the cold season:

• Inspect and Repair Seals
  • Start by checking your window frame for gaps, cracks, or worn-out caulking. 
  • If you find gaps around windows, use a caulking gun to apply a fresh bead of caulk or foam weatherstripping. Look for self-adhesive foam strips for an easy-to-apply solution.
  • Don’t forget to inspect the window sill and the bottom of the window sashes, where air leakage often occurs. 
• Add Window Insulation Film to Old Windows
  • Window insulation film is a cost-effective solution to prevent air leaks from drafty windows. It creates an additional layer between the window and the room, minimizing heat transfer.
  • The window film, which you can find in window insulation kits at hardware stores, is usually applied with double-sided tape and a hairdryer to shrink it tightly to the glass panes.
• Hang Heavy Drapes
  • Heavy drapes or thermal curtains are a simple yet effective way to weatherproof your windows. 
  • Choose close-fitting drapes that cover the entire window frame, and consider insulated curtains for maximum energy efficiency. For the best results, keep them closed during the colder months to trap heat inside your home.
• Use Sealant Foam
  • Sealant foam is applied in the same fashion as caulk around the perimeter of the interior window. Some people prefer to use something less messy and easily removable. The solution is vinyl or rubber weather stripping material.
  • Weather strips often have adhesive on the back for easy application. If you prefer a different method to create a barrier between your window and the outside and prevent heat transfer, condensation, and mildew growth, add staples every 6 inches to the window frame. 
• Use Draft Stoppers
  • Placing draft stoppers along the bottoms of windows and doors can block out drafts. You can buy fabric tubes filled with foam or make your own with common materials.
  • Closed-cell foam or foam tape strips are another alternative, providing a tight seal against air drafts for casement windows and double-hung windows.

Best Way to Insulate Windows for the Winter: Long-Term Solutions

In terms of weatherproofing durability, you get what you pay for. If you take a cheap and straightforward approach, it will likely only last for a while and fail to prevent energy loss. Weatherproof stripping, for instance, needs to be replaced often due to the degradation of the rubber. Vinyl gaskets are typically removed after the winter is over.

Some people prefer to take permanent action to enhance their home’s windows. Long-term options with good thermal properties include shades, energy-efficient windows, or insulating shutters.

• Install Shades or Shutters
  • Not only do shades look great, but they also contain side pockets called cells. These cells trap air in the pockets and prevent it from flowing inside, increasing the airtightness of windows.
  • Another stylish option is insulating shutters. Because they can be closed, shutters provide a complete blockage of airflow into the home. 
• Install energy-efficient weather-seal windows
  • If your current windows are older or showing significant wear, consider upgrading to energy-efficient, weather-seal windows. These windows are designed with tight seals and double-pane glass to provide excellent insulation, reducing air leakage and energy loss.
  • While it’s a bigger investment, installing energy-efficient windows can significantly lower your energy costs over time and is a great permanent solution for keeping your home comfortable in all seasons.
• Install Storm Windows
  • Storm windows offer an additional layer of insulation by sealing in warm air and reducing heat loss through single-pane windows.
  • They’re easy to install and provide an airtight seal, making them an ideal permanent solution for energy-efficient windows. Look for double-pane storm windows for even better thermal properties.
