Old, inefficient windows allow for heat loss throughout your home, causing your HVAC system to work harder to keep your home at a comfortable temperature. While installing new windows is the best way to fix the issue, there are things you can do to prepare your old windows if you’re not quite ready to replace them.

Inspect the weatherstripping

Look at the weatherstripping around your windows to see if you notice any leaks, gaps, or damage. If you don’t see anything visually, hold a candle or lighter near the window to see if the flame moves more than usual. If it does, there are small gaps you should fix. Head to your local hardware store to pick up some new weatherstripping and follow the instructions to replace it.

Check the Caulking

You should also look at the original line of caulk between your window trim and the wall. Does it look dried out or show signs of cracking and flaking? If so, remove it with a putty knife and wipe the area clean. Then, dry it completely before applying new caulk. We recommend using a silicone-based caulk for best results.

Check the Frames for Signs of Rot

As you’re doing your window inspection, check to see if any parts of the frame are damaged or showing signs of rot. Fix any issues you notice as quickly as possible before more serious issues develop. Contact a professional window replacement company like Semper Fi Roofing & Exteriors to learn more about how to replace damaged window frames.

Learn How to Prevent Condensation Issues

Have you ever noticed your windows “sweating” during the winter? This happens when the dry, cool winter air comes in contact with moist, warmer air. This excess moisture on your windows can lead to rot on the molding and frames. Help combat condensation buildup during the winter by getting a dehumidifier that you can use to help lower humidity levels.

Consider Installing Storm Windows

Adding storm windows to your home can give your old windows extra insulation. They’re a very efficient option, helping to keep your home at a more comfortable temperature all winter long. Best of all, they can be installed either temporarily or permanently.

Add an Extra Layer of Insulation

Looking for a budget-friendly way to insulate your windows? Cover the inside of your windows with clear plastic sheets to add extra insulation. At your local hardware store, you can find cheap window insulation kits that come with all the supplies you need. Then, just cut the sheets to fit your windows, apply the heat-shrink plastic to them, and you’re good to go. In the spring, you can then remove the plastic without doing any damage to your windows.

Keep Your Windows Locked

This tip is a simple one! When your windows are closed, keep them locked. Unlocked windows aren’t sealed as tightly, which can allow cold drafts in, especially with older windows. Keeping them locked is a simple update that can make all the difference.

Get a Professional Window Inspection

Structural damage to your windows isn’t always easy to see unless you know what to look for. Consider scheduling a professional window inspection to get a full overview of the state of your windows. They’ll check for things like small cracks, broken glass, and small gaps so you have a better idea of whether there are any issues that need immediate repair.
