Something is creaking on the topmost floor, and yet you all know that no one's there. Why did your door slam shut seemingly by itself? Could ghosts be causing your lights to flicker? You love your home, but it seems to be producing a variety of creepy and unexplainable noises. Sometimes, experiencing only one or two things is enough to suspect your house might be haunted.

And since it's Halloween, it’s easier to think that there must be some supernatural connection to these eerie property issues. But before you get the jitters, chances are that a lot of these ‘hauntings’ and happenings have not-so-scary reasons as to why they occur. Here’s a look at some of the most common issues in your home that may be causing the hair on the back of your neck to rise, and a few simple fixes to ease your mind.

Spooky problem #1: Flickering lights

Are the lights in your home turning on and off at random times? It's easy to regard this as a paranormal phenomenon, especially if you’re home alone and need to go to the bathroom in the wee hours of the morning. But rather than ghosts or ghouls causing this unearthly scene, the flickering is most likely due to faulty wiring, loose bulbs, or fluctuating voltage. 

In older houses, flickering lights were almost expected since electrical wiring wasn’t always up to modern standards.

The fix: There could be a dozen reasons why lights flicker, and many of them can be dangerous. You could do some minor fixes, such as making sure you installed the correct bulb with proper wattage or that the bulb is tightened properly. And instead of calling an exorcist, get a licensed electrician to inspect your property. Depending on the age of your home and whether there have been any electrical upgrades performed, you may have knob and tube wiring which can become loose or damaged over time, a defective switch, or an overloaded circuit — all of which should be handled only by a professional to ensure that your home is up to code.

Spooky problem #2: Creaking floors

It's the middle of the night and you’ve stopped whatever you’re doing to listen closely. It’s that creepy creaking noise! No wonder you’ve got goosebumps. But several potential factors could be the reason for your home’s creaking floors. The paranormal, fortunately, or unfortunately, isn’t one of them. Creaking spots are common on hardwood, laminate, vinyl, or even carpeted floors. The change in weather in regards to humidity and cold can cause your substructure to expand and contract seasonally. 

Likewise, sounds that resemble footsteps can be due to the settling noises in the structure, which are common occurrences in homes with larger open spaces or attics. An improperly fastened subfloor can also cause creaks when you walk over areas where screws or nails may have loosened or possibly were not fastened correctly.

The fix: Hiring a handyman or a carpenter is your best bet to fix the problem. Since your floor joists can buckle and twist due to weather or settling, you may require joist bridging to help eliminate the twisting and causing further issues which result in more creaks.

Spooky problem #3: Cold spots in certain areas

Cold spots don't automatically mean there’s a ghost nearby or a spirit passing by. Cold spots are common, especially in older and multilevel homes. They may be due to insulation not being properly installed, is actually nonexistent, or was damaged in some way. Or it could be due to some gaps or cracks in windows or siding that are letting in more air, causing a cold spot or draft. 

The fix: There are several ways to eliminate cold spots. You may add insulation and seal any gaps under doors and windows by using caulk or weatherstripping. If there’s an issue with your HVAC system itself, an expert will be able to offer solutions to fix it.

Spooky problem #4: Doors that open or close on their own

Whether or not you believe in the supernatural, doors that would slowly creak open on their own feel like a scene from any horror movie. Rest assured, it's only normal because as the house begins to settle over time, the door frames can become unlevel and out of plumb. This can cause the weight of the door to close or open on its own.

The fix: To stop being haunted by a door that’s opening and closing by itself, it’s better to bring in a qualified carpenter to align the hinge and fix the issue, especially if you can’t DIY.

Spooky problem #5: Scratching inside the walls and/or in the basement

Hearing scratching noises and scurrying at night? It can be terrifying, yes. But with the colder months just around the corner, the more plausible explanation is that there may be critters in your wall. Animals such as rats, squirrels, and even skunks and raccoons, can find their way into your home through openings in your crawl spaces and cause a variety of problems. Moreover, the bacteria from their wastes and/or carcasses can become airborne and cause toxic health hazards.

The fix: Unfortunately, calling Ghostbusters in this kind of situation isn't gonna help. Depending on what critter is involved, a pest- or animal-control service may be what you need. You can also mitigate the problem by investigating and sealing off possible entry points with a metal screen or wood. Clean your backyard and garage, keep your garbage cans clean and tidy, and make sure pet food and birdseed are stored in gnaw-proof containers.
