The Main Causes of Window Air Leaks

So, why are you feeling cold air coming through your windows? It’s often due to poor seals, gaps between the window frame, or damage to the window itself. While temporary solutions like weatherstripping may help, the most effective long-term fix is to upgrade to modern, energy-efficient windows designed to prevent drafts.

These are the four most common reasons for window air leaks:

Broken Seal – There’s no question that this is one of the most common culprits behind your windows leaking cold air. As some window frames sit in the sunlight, they expand and contract. Over time, this expansion and contraction causes the seal between the window frame and the glass to break. This breakage causes air to be able to infiltrate right through to the inside of your home.

Exterior Damage – In some cases, the outside window frame can become damaged. Whether it’s a small issue like the weatherstripping getting knocked loose or cracks in the frame, this kind of damage can let air in. If the problem is fairly minor (like weatherstripping), this is one of the causes of window air leaks that can be repaired, instead of fully replacing your windows.

Gaps During Installation – While generally older windows are more likely to be drafty, these leaks can affect newer windows, too. For example, if the construction team that built the house rushed the job, they may have left small gaps between the window frame and the wall. While they may be difficult to see with the naked eye, you’ll be able to feel the drafty air.

Low-Quality Glass Window – Although this generally is not an issue with any recently installed windows, some very old windows may just be made with energy-inefficient glass that doesn’t provide insulation and lets the air right through. So, if this is the window you unfortunately have, there could be nothing else wrong with it, yet you’ll still experience the tell-tale draft of a window air leak.

In the vast majority of cases, the best way to stop drafty windows is to replace them with an attractive and energy-efficient upgrade. While minor exterior damage – like missing weatherstrip – can be repaired fairly simply, all of the other causes of window air leaks require replacement. Not only is repairing sub-par windows not cost-effective, but you also miss out on all of the advantages that new windows deliver, including:

  • Reduced Energy Bills in Every Season
  • Attractive Interior & Exterior Styles
  • Boosted Property Value
  • Guaranteed Air Leak-Free Protection

We recently completed a major renovation with Choice Home Remodeling, and we couldn’t be happier with the results. This project involved a full first-floor layout change, a brand new kitchen, adding a bathroom, and a roof replacement—so it was a significant undertaking. From start to finish, their team handled everything with professionalism, organization, and clear communication.

One thing that really sets them apart is their consistency. We’ve used Choice Home Remodeling for several projects over the years, including smaller jobs, and they approach every project—big or small—with the same level of care, attention to detail, and commitment to quality.

Throughout this renovation, they kept us informed every step of the way and were always proactive when it came to addressing questions or unexpected challenges. The craftsmanship is excellent, and it’s obvious they take pride in their work.

We’re thrilled with how everything turned out and would highly recommend Choice Home Remodeling to anyone looking for a reliable, skilled, and trustworthy contractor.

We recently replaced our original 2007 steel front door and had a great experience with Choice. Tim was very patient and helpful throughout the process, making sure we found the right door for our style and budget. We made three trips before deciding and never felt pressured.

The installer was also excellent—professional, polite, and clearly very skilled. You can tell he takes pride in his work.

We’re extremely happy with the end result and would definitely recommend Choice to anyone looking to upgrade their front door.
