For homeowners in Indianapolis, where summers are humid and winters can be brutally cold, energy loss can really drive up utility bills. It also puts extra pressure on your HVAC system and makes it harder to keep your home comfortable year-round.
If your home isn’t sealed tight, seasonal changes can lead to moisture problems, pest issues, and even structural wear. Taking time now to weatherproof your house means fewer surprises when the next storm hits.
Getting ahead of it doesn’t require a big budget or a long list of tools. Many steps are simple and cost-effective. And when you start early, you’ll have time to make smarter decisions about any upgrades.
Improve Insulation in Key Areas
Your attic and crawl space are two spots where poor insulation causes big energy losses. In winter, heat rises and escapes through the attic. In summer, hot air builds up and makes your air conditioner work harder. Without enough insulation, it’s harder to control the temperature indoors.
Check the insulation in these areas. If it looks thin, uneven, or wet, it’s time to replace or add more. Fiberglass batts and blown-in cellulose are two common choices. Some insulation types also help block moisture and pests. Adding proper insulation doesn’t just lower energy costs—it also helps extend the life of your heating and cooling systems.
Upgrade Old Siding for Better Efficiency
Some homes still have siding that’s decades old. While it might look okay on the surface, older materials often don’t insulate well or hold up to extreme weather. Modern siding options like vinyl or fiber cement offer better energy performance and are built to last.
If you notice that your home feels drafty or your energy bills keep rising, it could be time to upgrade. Work with a trusted Indianapolis siding company to explore new siding types that work well for local weather. New siding can improve insulation, stop moisture problems, and give your home a fresh appearance.
Seal Gaps Around Doors and Windows
Doors and windows are common places where heat or cool air escapes. Even tiny gaps can let in cold drafts during winter or warm air in summer. That makes your HVAC system work harder and raises your energy bill.
Run your hand along the edges of your windows and doors. If you feel air coming through, that’s a sign you need to seal them. Use caulk for smaller gaps and weatherstripping for larger spaces. These materials are easy to find and simple to apply. This step alone can make a big difference in your home’s temperature and comfort level.
Install Storm Doors and Windows
If your home feels drafty even with closed doors and windows, you might benefit from adding storm protection. Storm doors and windows add an extra layer that helps block wind and keep heat or cool air inside. They also reduce outside noise and can make your main windows last longer.
These additions are not too costly and are usually quick to install. Some even come with screens so you can let in fresh air during mild weather without letting bugs inside. In regions with strong seasonal changes, they make a big difference in indoor comfort.
Check the Roof for Missing or Loose Shingles
Your roof takes on a lot throughout the year—sun, rain, snow, and wind. If you have shingles that are curling, broken, or missing, water can seep in and cause serious damage. Over time, that moisture can weaken your roof deck and even get into your attic or walls.
Walk around your home and look up at the roof. Look for uneven spots, lifted corners, or exposed nails. If you’re comfortable using a ladder, take a closer look, but never walk on the roof unless you know it’s safe. If you spot issues, get help from a roofing contractor. Fixing a few shingles now is easier than dealing with a leak after a storm.
Install Door Sweeps to Stop Drafts
Many homes lose warm or cool air through the gap under exterior doors. It may seem small, but it’s enough to change how your home feels inside. A simple fix is to install door sweeps. These are long strips that attach to the bottom of your doors and block air, dirt, and bugs.
They are easy to install and come in different sizes and materials. Choose one that fits snugly without making the door hard to open. You can find them at most hardware stores, and they’re often one of the cheapest upgrades on this list. You’ll notice the difference right away—especially near back doors or garage entries.
Inspect and Seal HVAC Ductwork
If your heating or cooling system doesn’t seem to work evenly across the house, the ductwork could be the problem. Ducts that run through attics, basements, or crawl spaces often develop leaks or gaps over time. This means your system uses more energy to maintain your set temperature.
Look for loose connections or areas where insulation around the ducts is damaged. If you’re not sure what to look for, consider hiring a technician for an energy audit. Sealing ducts with mastic or foil tape—not regular duct tape—can improve airflow and make your home feel more balanced room to room.
Getting your home ready before the weather shifts is one of the smartest things you can do as a homeowner. It helps lower your bills, improves indoor comfort, and protects your property from damage. You don’t need to take on everything at once. Start with the most obvious issues, like sealing cracks or cleaning gutters, and then move on to bigger upgrades as needed.
Even small changes—like adding a door sweep or sealing pipe openings—can have a big effect. And when you’re ready for more permanent fixes, such as new siding or better insulation, connect with local professionals who know what works in your area. A well-prepped home is a safer and more comfortable place to live—no matter what season comes next.
