My Home Stinks – What Is It and What Can I Do
There are times when I am at a home inspection and there is a smell in the home that usually is not strong but persistent and annoying. There are many areas odors can come from and simple maintenance that can repair them to keep your home smelling like you want to live there. I will explain many common smells in the home and what you can do to remedy the annoyance.
I am not talking about animal smells, that is a whole subject on its own
Sewer odor can come from many areas in the home, but here are some common areas to look first
- Drain traps, if there is a drain that has not been used in while; the water will evaporate and allow sewer gas to enter your home
- Damaged or broken waste line in the home, this will allow sewer gas to enter and build up in your home
- Improper venting of the sewer system, this also will allow sewer gas to enter the home
Many times, a bathroom will have a persistent smell of sewer and urine.
- The wax ring may be bad and leaking, if the toilet rocks or your see moisture around the wax ring, it’s probably bad
- If the wax ring is bad, the toilet will need to be pulled and the wax ring replaced
- There is the potential that the toilet is cracked, then the toilet will need replacing
- Damaged toilet flange, not allowing the toilet to seal correctly
- This should be performed by a qualified plumber
If there is a smell noticed around a sink and the trap has been checked and is good, there are several areas to check
- Check the sewer line for any cracks that would allow sewer gas to escape
- Check the overflow for any debris and food that may have gotten stuck in it.
- Food and debris stuck just below the drain lid or under the pull up stopper in the bathroom drain
Garbage Disposal Smells:
Garbage disposals are a common area of odors, because of everything people like to put in them. They are required to be cleaned.
- First you want to clean the rubber flaps to remove trapped food and don’t forget to get under the flap
- I recommend running a couple cups of ice with cold water, this will break food particles loose allow the water to wash them down the drain
- Next put lemon or orange rinds to help remove deposits and give a clean aroma
Dishwashers like disposals will require cleaning also. It’s a good idea to clean it monthly. There are several dishwasher cleaners that can be purchased, they work good enough but what I recommend to my clients is:
- Remove the lower basket and clean out all visible debris, then put the basket back in
- Put a cup of bleach on the top basket and run a wash cycle
- DO NOT ALLOW TO GO THOUGH DRY CYCLE
- Dump the excess left in the cup and pour in a cup of white vinegar and run the dishwasher though a new clean cycling allowing it to go through the dry cycle
Sewer Smell from Hot Water:
Hot water can have a sewer smell if there is bacteria in the water because the hot water will react with the bacteria. Water high in sulfur will give the water a smell like rotten eggs. This is not harmful to drink, but the smell is not pleasant.
- To help with the bacteria, you can have a professional shock your well
- Shock chlorination is the process by which home water systems such as wells, springs, and cisterns are disinfected using household liquid bleach (or chlorine). Shock chlorination is NOT a recommended method for treating recurring bacteria problems.
- A home owner can also install special water filtration systems to remove the bacteria
Fireplace Smoke Smells:
If the home is using a wood burning fireplace, the chimney needs cleaned and inspected annually.
- Damper needs to be sealed when the fireplace is not in use. When using any vents or dryer in the home it can create a negative pressure pulling air and odors into the home
- Clean out needs to be sealed also for the same reason above
Performing simple maintenance can help to prevent unwanted odors in your home, making it more comfortable and inviting, for you and your guests.
