As a Maryland homeowner, you’re well aware of the harsh winters that can take a toll on your comfort and your wallet. Maximizing the energy efficiency of your home during the cold months is a top priority, but you’re determined to do so without watching your energy bill skyrocket. One key element to achieve this goal is ensuring that your windows are well-sealed. In this article, “How to Reseal Windows,” we’ll walk you through the essential steps to seal your windows effectively, preventing drafts and maintaining a cozy indoor environment throughout the winter season. By the time you finish reading, you’ll be equipped with the knowledge and techniques to not only keep the chill out but also keep your energy expenses in check.
What are Window Seals?
Window seals, often known as insulated glass units, are an essential part of modern windows. These seals hold in the air between multiple panes of glass. Unlike older single-pane windows, modern windows have two or sometimes three panes separated by layers of air or inert gas and sealed with elastic sealant. This construction enhances insulation and energy efficiency, making them more suitable for today’s homes.
What Causes Window Seals to Fail?
Window seal failure can happen for various reasons, but one common culprit is solar pumping. This occurs as the sun shines on your windows, causing the glass to expand and put pressure on the seal. At night, the glass cools and contracts. Over time, this cycle can lead to seal failure, especially in windows exposed to ample sunshine, like those on the south and west sides of your home. Other reasons for seal failure include poor installation, damage from heat during painting, harsh chemicals used in painting, high winds, and house settling.
How to Tell If Your Window Seals Have Failed
Fogged windows are a clear sign of window seal failure. Moisture enters between the glass panes and condenses, causing fog. Even if the fog disappears temporarily, the underlying seal issue remains. In windows with inert gases, losing the seal means losing their insulation benefits, which can lead to warping, collapsing, or cracking.
Steps to Reseal Windows in Your Home
Checking for Drafts:
- Light a candle inside your house.
- Slowly move the flame along the window edges.
- Wherever the flame flickers strongly, a draft is present.
Caulking Window Seams:
- Apply a caulk softening product to old caulk on the outside.
- Wait for about 2 hours.
- Scrape off old caulk with a putty knife.
- Apply exterior-grade caulk at a 45-degree angle to window seams.
- Run a bead of caulk along the gaps.
- Seal the bottom seam.
- Smooth the caulk with a wet finger.
- Check for loose glazing by tapping the windowpane.
- Scrape out old glazing with a putty knife.
- Clean the glass and frame edges.
- Apply new glazing between the windowpane and frame.
- Create a smooth surface with firm pressure.
- Allow several days for the glazing to dry before painting.
