Why Does My House Smell Like Rotten Eggs?

Why Does My House Smell Like Rotten Eggs?

Unless you have a carton of eggs in your living room, your house shouldn’t smell like rotten eggs, but you should know the reasons if it does.

Most homeowners want their homes to smell pleasant, but what if your house smells like rotten eggs?

You can easily distinguish the smell of rotten eggs, and it is definitely not a smell that you would want to be stuck in your house.

Gas leakage is one of the most common reasons why your house might smell like rotten eggs. Natural or sewer gas leakages can lead to your house smelling like rotten eggs. Additionally, humidity in the air can lead to toxic drywall and mold growth in homes, which can cause your home to smell like rotten eggs.

Your home is the place where you want to relax and unwind after a long day, but if your house smells like rotten eggs, it is certainly not the most comfortable place.

Since there are no detectors that indicate the presence of foul odors, you have to rely on your nose to sniff and notice any unusual smells.

If you recognize the smell of rotten eggs in your home, you should know what could be some of the potential reasons that can cause your house to smell like rotten eggs.

As experts in recognizing smells as a warning sign for a possible problem, we share some of the reasons why your house smells like this.

So let’s get started.

Why Does My Home Smell Like Rotten Eggs?

Gas Leakage

Perhaps the most common cause of rotten egg smell in homes is gas leakage.

It could be the leakage of natural gas or sewer gas leakage. Let’s take a closer look at each of the two types of leakages.

Gas Leak

Natural Gas Leakage

Naturally, gas doesn’t have the smell of rotten eggs. Instead, a substance that utility companies inject into the gas lines could potentially cause rotten eggs to smell in homes.

This is why as soon as you notice this smell, you should know that there is a gas line leakage in your home which needs immediate attention.

Sewer Gas Leakage

Typically sulfur has a rotten eggs smell, and you may experience this smell in your home if you have a sewer gas leakage.

If you suspect sewer gas leakage, know that sewer gas also contains toxic elements that can lead to health issues, including fatigue, dizziness, headaches, and loss of appetite.

Therefore, it is critical to identify and rectify the gas leakage in your home as soon as possible.

It is best to call a professional plumber so they can investigate the source and fix the leakage immediately.

Humidity That Leads to Toxic Drywall

Apart from gas leakages, another possible cause of the unwanted smell of rotten eggs in your home could be an issue with your drywall.

If you live in an area that experiences a high level of humidity in the air, it can cause sulfur in the drywall to release a gas that can cause your home to smell like rotten eggs.

Moreover, the gas release can cause health problems and can also corrode any exposed wiring and copper pipes in your home.

If your plumber has assured you no leakages in your home, toxic drywall could be a possible cause of smell like rotten eggs; however, fixing this problem is not a DIY job.

You will need to get in touch with a professional who can rip out any damaged sheets and replace them as soon as possible.

Mold Growth in Your Home

While mold growth in homes typically has a musky odor, some people may describe the smell caused by mold growth as the smell of rotten eggs.

Mold growth in your home may not always be a major inconvenience and often does not cause health problems, but certain types of molds can be dangerous, so it is integral to address this problem immediately.

Some homeowners may try a few DIY solutions to get rid of mold growth, but the most effective solution comes from professionals who are trained to help you get rid of all types of molds.

Dirty Garbage Disposal

One of the other possible reasons why your house smells like rotten eggs could be your dirty garbage disposal.

When you do not clean your garbage disposal regularly, the odor-causing bacteria can reside in the garbage disposals, grow from garbage scraps, and cause a foul odor in your home.

Conclusion to Your Home Smelling Like Rotten Eggs

There could be many reasons why your home smells like rotten eggs. Most commonly, however, it’s because of a gas leak, humidity levels, or mold growth.

All of these things are issues that should be rectified immediately if you notice them, as they can all possibly damage your health.
