how to stop a drafty window

A drafty window can be a real nuisance, letting cold air in during winter and hot air out in summer. This not only makes your home uncomfortable but also significantly increases your energy bills. Fortunately, there are several ways to tackle this problem, ranging from simple DIY solutions to more permanent fixes. This guide will walk you through effective methods to stop that pesky draft and keep your home cozy and energy-efficient.

Identify the Source of the Draft

Before you start applying solutions, it's crucial to pinpoint the exact source of the draft. Is it coming from the frame, the glass panes, or the seal around the window?

  • Feel around the window frame: Gently run your hand along the edges of the window frame, paying close attention to the areas where the window meets the wall. You'll likely feel a noticeable temperature difference where the draft is strongest.
  • Look for gaps and cracks: Carefully inspect the window frame, the seals, and the panes for any visible gaps or cracks. These are common culprits for drafts.
  • Use incense or a smoke stick: Light a stick of incense or a similar smoking object and hold it near the window. Watch the direction the smoke flows – it will be pulled towards any gaps or leaks.

Simple and Affordable Solutions to Stop Drafty Windows

These methods are inexpensive, easy to implement, and can make a noticeable difference in reducing drafts.

1. Weatherstripping

Weatherstripping is an incredibly effective and inexpensive solution for sealing gaps around window frames. Various types are available, including foam tape, rubber seals, felt, and vinyl. Choose the type that best suits your window type and the size of the gap you're trying to seal. Applying weatherstripping is a simple DIY project that requires minimal tools.

2. Window Insulation Film

Window insulation film is a thin, plastic film that you apply to the inside of your window. It creates an extra layer of insulation, effectively reducing drafts and improving energy efficiency. This is a particularly effective solution for older windows with single-pane glass. Many kits are available and are easy to install.

3. Caulk

Caulk is a versatile sealant used to fill gaps and cracks around window frames and other areas where air leakage occurs. Choose a caulk that is specifically designed for exterior use and is paintable if you wish to match the color of your window frame. Proper caulking can significantly improve the seal around your window, preventing drafts and water leakage.

4. Draft Stopper

Draft stoppers are simple, inexpensive solutions that can be placed along the bottom of a drafty window to block the cold air. They are typically long tubes filled with fabric, sand, or other materials. You can even make your own using old fabric scraps!

5. Curtains and Drapes

Heavy curtains or drapes can act as an additional layer of insulation, helping to prevent drafts and improve overall energy efficiency. Choosing curtains made from thick, insulating materials like velvet or fleece will maximize their effectiveness. Make sure the curtains extend beyond the window frame to cover any gaps.

More Involved Solutions for Severe Drafts

If the simple solutions don't completely eliminate the draft, you may need to consider more involved options.

1. Window Repair or Replacement

If your windows are severely damaged, cracked, or significantly deteriorated, repairing or replacing them is the most effective long-term solution. This will provide a permanent solution to the draft issue and significantly improve the overall energy efficiency of your home. Consider investing in energy-efficient windows with double or triple-pane glass.

2. Professional Window Sealing

If you’re uncomfortable tackling the repairs yourself, hiring a professional to seal your windows can ensure a proper and long-lasting solution. They have the expertise and tools to address more complex draft issues.

Saving Money and Improving Comfort

By addressing drafts in your windows, you'll not only improve the comfort of your home but also significantly reduce your energy bills. Implementing even one or two of the methods discussed above can make a considerable difference in how effectively your home is insulated, keeping you warm in winter and cool in summer and saving you money all year round.
