Q: Is it normal for windows to rattle in the wind?

• <div><p>No, it&rsquo;s not normal for windows to rattle in the wind. If they do, it may signal that there&rsquo;s a larger problem at play. Common reasons that windows rattle in the wind are because the glass isn&rsquo;t secure enough, the frame is loose, or the wood is rotting. In any of these cases, you should identify the problem and take steps to fix it.</p></div>

Q: Does condensation on windows mean poor insulation?

• <div><p>Actually, condensation can mean that your windows are more energy efficient because the seal keeps cold air out and warm air in. In some cases, windows with poor seals can lead to more condensation, but they may allow the cold and warm air to mix and reduce condensation. If you&rsquo;re worried about whether or not your windows are properly insulated, have a pro assess them.</p></div>

Q: Can you make an existing window bigger?

• <div><p>Yes, you can always make an existing window bigger, but the job complexity varies widely depending on the location of the window and the framing around it. Exterior walls are always load-bearing, so making windows wider will require structural changes that make for a more complex but doable project. Making windows taller often won&rsquo;t require structural changes.</p></div>

Q: How can I improve the energy efficiency of my windows?

• <div><p>Upgrade to double-glazed glass or apply energy-efficient coatings to reduce heat loss and utility costs.</p></div>

Q: Should I replace 20-year-old windows?

• <div><p>In short, it depends. After 20 years, the glass in your windows is less energy efficient, which can cause increased electricity bills. You might also see signs of water damage or natural wear and tear over the years. However, with proper maintenance, some window frames can last up to 50 years, so you may only need to replace the glass to save on energy. </p><p>At the same time, window replacement is a major investment, so replacing the glass in rooms most impacted by outdoor temperatures is one way to avoid going all-in to replace your windows.</p></div>
