20 Things Every Homeowner Should Know How to Do
Owning a home is exciting — but it also comes with responsibilities. From small maintenance tasks to emergency fixes, knowing how to handle the basics can save you time, money, and stress.
Whether you’re a new homeowner in Bethesda, MD, or you’ve lived in your home for years, these are 20 essential things every homeowner should know how to do.
1. Shut Off the Main Water Supply
In an emergency — like a burst pipe — knowing where your main water shut-off valve is can prevent major flooding and costly water damage. Locate it (usually in the basement or near your water meter) and make sure it turns easily.
2. Reset a Tripped Circuit Breaker
If your power suddenly goes out in one room, check your breaker panel. Flip the tripped breaker off, then back on. Labeling each switch helps you quickly identify which area it controls.
3. Unclog a Drain
Avoid calling a plumber for simple clogs. A plunger, drain snake, or baking soda + vinegar can often do the trick. Stay away from harsh chemicals that can damage pipes.
4. Change the HVAC Filter
Replace your air filters every 1–3 months to keep your system running efficiently and improve indoor air quality. Dirty filters make your HVAC system work harder — and cost more to operate.
5. Test Smoke and Carbon Monoxide Detectors
Check your detectors monthly and replace batteries at least once a year. These small devices save lives and are often overlooked.
6. Locate the Gas Shut-Off Valve
If you smell gas, you should immediately shut off the gas and leave the house. Knowing the location of your gas shut-off valve (usually near your meter) is essential for safety.
7. Fix a Running Toilet
A constantly running toilet wastes gallons of water daily. Most of the time, replacing a flapper or fill valve is all it takes to stop the flow.
8. Clean the Gutters
Clogged gutters cause roof leaks and foundation issues. Clean them at least twice a year, especially after fall leaves or heavy storms.
9. Seal Drafts and Air Leaks
Use weatherstripping or caulk around windows and doors to keep warm air in and cold air out. This simple task can lower energy bills significantly.
10. Turn Off Water to Individual Fixtures
Under every sink and toilet is a local shut-off valve. Knowing how to use them helps you isolate small leaks without shutting off your entire home’s water.
11. Patch Small Drywall Holes
You don’t need to hire a contractor for nail holes or dents. A little spackle, sandpaper, and touch-up paint go a long way in keeping walls fresh.
12. Know How to Use a Fire Extinguisher
Always keep a working ABC fire extinguisher in your kitchen or near your furnace. Remember the acronym PASS: Pull, Aim, Squeeze, Sweep.
13. Clean the Dryer Vent
Lint buildup is a leading cause of house fires. Clean your dryer vent and lint trap regularly to improve safety and dryer efficiency.
14. Check and Maintain Your Sump Pump
If you have a basement, test your sump pump before heavy rain. Pour water into the pit to ensure it activates properly — a dry basement depends on it.
15. Flip the Breaker for Resetting Appliances
When large appliances stop working, try flipping their dedicated breaker before calling for service. Sometimes, it’s just a simple reset.
16. Know How to Shut Off Water to Your Water Heater
If you ever need to replace or service your water heater, you’ll need to know how to shut off both water and power/gas to it safely.
17. Check the Water Pressure
Too much pressure can damage plumbing and appliances. A water pressure gauge (available at hardware stores) helps you monitor and adjust as needed.
18. Clean Refrigerator Coils
Dusty coils make your fridge work harder. Clean them every 6–12 months to keep it cooling efficiently and extend its lifespan.
19. Locate Your Septic Tank or Clean-Out Pipe
If you’re not on city sewer, know where your septic tank or main clean-out is. It’s helpful for maintenance or in case of a backup.
20. Know When to Call a Professional
While DIY is great, some jobs — like electrical wiring, major plumbing, or structural changes — should always be left to the experts.
