Let’s talk about something that can make a huge difference in your comfort and energy bills: sealing air leaks. Whether it’s chilly drafts sneaking in through your windows or cold air slipping under your doors, those leaks are robbing your home of warmth. If you’re struggling with heating in Union, I’ve got practical advice to help you keep the warm air in and the cold air out.
The first step is identifying where the air is escaping. Common culprits include windows, doors, attics, basements, and even your ductwork. You might notice drafts, uneven temperatures, or higher-than-usual energy bills—these are all signs that your home isn’t sealed as well as it could be.

DIY Air-Sealing Tips
For those of you who enjoy a hands-on approach, there are a few things you can do yourself.
- Weatherstripping: Apply weatherstripping around doors and windows to close gaps. This simple fix prevents cold air from sneaking in and warm air from escaping.
- Window Film: Installing shrink film over windows during the winter months creates an extra layer of insulation. It’s inexpensive, easy to install, and can dramatically reduce drafts.
- Door Sweeps: Adding door sweeps to exterior doors seals the bottom gap, keeping cold air out and your heated air in.
- Caulking: For small cracks and gaps around window frames, baseboards, and plumbing penetrations, a high-quality caulk works wonders.
These DIY measures are great for minor leaks, but sometimes the problem is bigger than a few gaps or drafts. That’s where professional help comes in.
When to Call the Pros
If you’ve sealed windows and doors but still notice cold spots or high energy bills, it’s time to call in a professional. Insulation and duct sealing are two areas where expert attention makes a big difference. Proper insulation in your attic, walls, and crawlspaces keeps heat where it belongs. And duct sealing ensures that the warm air your system produces actually reaches every room in your house—not lost in hidden leaks.
