Why Does My House Smell Like Sewer in the Winter

There are a few reasons why your house might smell like sewer in the winter. One reason could be that your drains are freezing and not draining properly. Another reason could be that you have a leak in your sewer line.

If you think you might have a leak, it’s important to call a plumber right away to fix it.

If you’ve ever noticed an unpleasant sewer smell in your home during the winter, you’re not alone. This is a common problem that can be caused by a variety of factors, from simple plumbing issues to more serious problems with your septic system.One of the most common causes of a sewer smell in your home is due to a dry P-trap.

The P-trap is designed to hold water in order to create a seal that prevents sewer gases from entering your home. However, if the P-trap dries out (which can happen if there’s not enough water flowing through it on a regular basis), those gases can escape and make their way into your home.Another potential cause of a sewer smell in your home is cracks or gaps in your plumbing pipes.

These small openings can allow sewage gases to escape and enter your home, leading to that unpleasant odor. In some cases, these cracks or gaps may also allow water from the sewers to leak into your home, which can lead to even more serious problems.If you have ruled out these simpler causes of a sewer smell in your home, it’s possible that there may be an issue with your septic system.

If you have a septic tank, it’s important to have it pumped regularly (generally every 3-5 years) in order to prevent any build-up of sewage or wastewater inside the tank which could lead to odors escaping into your home. Additionally, if there are any leaks in the pipes leading from your septic tank to your house, this could also allow sewage odors into your living space.If you’re dealing with a sewer smell in your home this winter, don’t ignore it!

While it may seem like a minor nuisance, it could be indicative of bigger problems that need to be addressed by a professional before they cause even more damage (and smells) down the road!

Can Cold Weather Cause Sewer Smell?

When the weather outside is cold, you may notice your sewer smell more. This is because cold weather can cause your sewer pipes to freeze. When this happens, the water in the pipes can’t flow properly and starts to back up.

This can cause a nasty smell to come into your home through your drains. If you think your sewer smell is due to frozen pipes, you should call a plumber right away to thaw them out before they burst.

How Do I Get My House to Stop Smelling Like Sewer?

If your home smells like sewer, it is most likely due to a problem with your plumbing. The first step is to check all of your drains and make sure they are clear. If you have a clog, you can try using a plunger or a drain snake to clear it.

If that doesn’t work, you will need to call a plumber.Once you have cleared the drains, you should take measures to prevent the problem from happening again. First, pour some baking soda down the drain and flush with hot water once a week.

This will help keep the drains clean and free of odor-causing build-up. You should also avoid putting grease and food waste down the drain. Grease can solidify in the pipes and cause clogs.

Food waste will decompose and create bacteria that can cause an unpleasant smell.

Why Does My House Occasionally Smell Like Sewer?

If your house occasionally smells like sewer, there are a few possible explanations. First, if you have a garbage disposal, food scraps can sometimes get trapped in the pipes and cause a smell. Second, if your home has an old or faulty septic system, sewage can backup into your home and cause a smell.

Third, if there is water leakage somewhere in your home, that could also be the source of the smell. If you’re not sure where the smell is coming from, call a plumber to come and take a look.

Why Does Sewer Gas Smell Come And Go?

When it comes to sewer gas, there are a few things that can cause that distinct smell. First off, sewer gas is made up of a mixture of different gases, including hydrogen sulfide and methane. These gases are produced when organic matter breaks down in anaerobic conditions – which can happen in a septic tank or sewage system.

The gases then escape into the air through cracks or holes in the system.The second reason why you might notice your sewer gas smell coming and going has to do with the weather. Colder temperatures will cause the gas to condense and become more concentrated, making it more noticeable.

On the other hand, warmer weather will cause the gas to disperse and dissipate more quickly. So if you’re noticing that your home smells like a sewer after a cold snap, that’s probably why!If you’re concerned about sewer gas smells in your home, there are a few things you can do to help mitigate them.

First, make sure all of your drains are properly sealed and free of any cracks or holes. This will help prevent gases from escaping into your home in the first place. You can also have a professional inspect your septic tank or sewage system to look for any potential problems that could be causing gases to escape.

Sewage Smell in House Comes And Goes

If you’ve ever had the misfortune of smelling sewage in your home, you know it’s an incredibly unpleasant experience. Unfortunately, it’s also a relatively common one. There are a number of potential causes for a sewage smell in your house, and often, it can be difficult to pinpoint the exact source.

However, there are some steps you can take to try to identify the problem and get rid of the stink for good.One common cause of a sewage smell in your home is a clog in your sewer line. If this is the case, you’ll likely notice that the smell comes and goes, depending on how much water is flowing through the line at any given time.

To check for a sewer line clog, flush all toilets in your home at the same time and see if the smell gets worse or disappears altogether. If flushing doesn’t make a difference, try pouring several gallons of water down each drain in your house (one at a time) to see if that clears things up. If neither of these methods works, you may need to call a professional plumber to take a look at your sewer line.

Another possible cause of sewage odor in your home is leaks from either your sewer line or from fixtures like toilets or sinks. These types of leaks can allow sewer gas to escape into your home, causing that characteristic foul smell. To check for leaks, start by checking all visible pipes for any signs of moisture or dripping water.

Then move on to inspecting all fixtures (toilets, sinks, showers/tubs) to make sure they’re not leaking around seals or gaskets. If you suspect there may be a hidden leak somewhere in your plumbing system, contact a professional plumber so they can use specialized equipment to locate and repair it.In some cases, sewage smells can waft into homes from outside sources like nearby manholes or septic tanks.

This is especially common if there’s been heavy rains lately which can inundate these systems and cause odors to escape. If you think this might be the case where you live, open windows and doors near affected areas to help air things out until the smells dissipate on their own.


If you’ve ever wondered why your house smells like sewer in the winter, you’re not alone. Many homeowners experience this problem, and it can be a real nuisance. There are several possible causes of the problem, but the most likely culprit is a dry trap.

A dry trap is a small hole in your drain that allows air to escape when water is flowing through it. This hole prevents sewer gases from coming up into your home through the drains. However, if the hole becomes dry, those gases can escape and cause an unpleasant smell.

There are a few things you can do to prevent your trap from drying out. First, make sure that all of your faucets are turned off when you’re not using them. This will keep water from evaporating from the traps.

Second, pour a cup of water down each drain every week or so to keep the traps filled with water. Finally, if you have an outdoor drain that’s prone to freezing in cold weather, pour some antifreeze down it before winter arrives to keep it from freezing solid.Following these tips should help eliminate any sewer smells in your home this winter.

If you continue to have problems, contact a plumber for assistance.
