Knoxville Winterizing Checklist — 20 Things Every Homeowner Should Do Before a Cold Snap

1. 🚰 Insulate exposed pipes in unheated areas
Wrap any exposed water lines in your crawlspace, garage, or unfinished basement with foam pipe insulation. This helps prevent frozen pipes and expensive bursts when temps drop below freezing.








 

2. 🧊 Cover and disconnect outdoor faucets
Unhook all hoses and drain them before storing. Add insulated faucet covers to every outdoor spigot so cold air doesn’t freeze the line inside your wall.
 

3. ⛔🚿 Know where your main water shutoff is
Find your main water shutoff valve now and make sure it actually turns. In an emergency leak or burst pipe, shutting the water off fast can minimize damage.
 

4. 🌬️ Seal gaps around drafty windows and doors
Feel for cold air coming in around trim, sills, and frames. Use caulk and weatherstripping to seal cracks so your heat isn’t leaking straight outside.








 

5. 🚪 Install or replace worn door sweeps
If you can see light under an exterior door, you’re losing heat. A simple door sweep helps block cold air, dust, and even bugs from sneaking in.

6. 🪟 Add window film to cold, drafty rooms
Apply clear insulation film on older or leaky windows, especially in bonus rooms or rooms over the garage. It adds an extra barrier against cold air without replacing the window.

7. 🌀 Change your HVAC filter regularly
A dirty filter makes your system work much harder and can raise your energy bill. Swap it every 1–2 months during heavy winter use to keep airflow strong and air quality better.
 

8. 🔥 Schedule a heating system checkup
Have a professional inspect your furnace or heat pump before the coldest part of winter. They can catch safety issues, carbon monoxide risks, and efficiency problems early.
 

9. 🌡️ Open vents and clear return grilles
Make sure vents aren’t blocked by furniture, rugs, or boxes. Good airflow helps your system heat more evenly and prevents hot and cold spots in the house.








 

10. 🌧️ Clean gutters and downspouts thoroughly
Remove leaves, sticks, and gunk so water can drain like it should. Clogged gutters can overflow, freeze, and cause roof leaks or foundation problems.

11. 🏠 Inspect your roof from the ground
Look for missing, cracked, or lifted shingles with your eyes or phone camera. Catching small issues now can prevent water from getting into your attic and ceilings later.
 

12. 🧱 Seal gaps in siding, trim, and around penetrations
Look around windows, doors, and places where wires or pipes enter the house. Fresh caulk keeps out cold air, moisture, and even small pests looking for a warm home.
 

13. 🪵 Check deck boards, posts, and railings
Walk your deck and feel for soft spots, loose boards, or wobbly rails. Winter moisture and freeze–thaw cycles can make existing damage worse, so fix it before it becomes unsafe.
 

14. 🚶‍♂️ Inspect and secure exterior steps and walkways
Look for cracked concrete, loose bricks, or shifting pavers where people walk. Add non-slip treads or grip tape to slick steps to reduce the risk of slips when it’s icy.
 

15. 💧 Look at drainage around your foundation
After a rain, see if water is pooling near the house instead of draining away. Adjust soil grading or extend downspouts so water flows away and doesn’t cause moisture issues.









 

16. 🕳️ Check your crawlspace or basement for moisture
Shine a light in and look for standing water, hanging insulation, or signs of mold. Catching these early makes repairs easier and helps protect your home’s structure and air quality.
 

17. 🚨 Test smoke detectors and CO detectors
Press the test button on each device and replace batteries if needed. Winter is when heating systems run most, so you want working alarms for both fire and carbon monoxide.
 

18. 🔌 Use space heaters safely
Only plug space heaters directly into a wall outlet, never into cheap power strips. Keep them three feet away from bedding, curtains, and furniture, and turn them off when you leave the room or go to bed.
 

19. 🧰 Put together a simple winter emergency kit
Keep flashlights, extra batteries, blankets, and bottled water in an easy-to-reach spot. If ice or wind knocks out the power, you’ll be glad everything’s already prepared.
 

20. ✅ Make a winter repair punch-list for a pro
As you go through the house, write down anything you don’t want to tackle yourself—like railings, gutters, caulking, or drywall repairs. Hand that list to a trusted local handyman or remodeler and knock it all out in one visit.
