I just found mold & mushrooms growing behind my toilet!!!?

I am very particular about cleaning, but after returning from vacation, I discovered thick mold and mushrooms growing behind the toilet in our guest bathroom. I am both disgusted and confused about how this could have happened. What are the potential causes of this growth? How can I prevent it in the future? What is the best way to clean it up—would bleach be effective?

I rented a house and went throught this issue.

Its actually been suggested not to use mold. I am searching this website through and through. It is the one my husband and I used.

HERE IS WHAT I FOUND:

Virtually everyone has one type or another of mold somewhere in their home. Although not all types are toxic, it is sometimes difficult to distinguish types without lab testing. Thus it is imperative to treat and remove all molds as if they’re potentially harmful. Regardless of the type of mold found, a home containing mold is not essentially a healthy home. Mold spores are very easily transported to different areas by attaching themselves to various hosts. These hosts would include people, animals, shoes and they even enter through open windows and doors. The spores then thrive and grow where it is damp and moist. Very toxic molds can develop from water seepage, and while black mold is “less common than other mold species it is not rare.”

How to Get Rid of Mold

don’t use humidifiers, unless humidity levels are below 30 percent relative humidity; avoid drying firewood indoors; operate bathroom exhaust fans during a bath or shower; use your range hood exhaust when cooking; avoid steam-cleaning carpets in winter; clean mold from wood and gyproc with a 10 percent to 30 percent solution of hydrogen peroxide applied with a spray bottle. This is more effective than bleach and water.

If you use chlorine bleach, mix one part bleach with two parts water and a little detergent to clean nearby surfaces. Leave for 15 minutes and rinse well. Use gloves, protective glasses and a tight-fitting dust mask, along with good ventilation. Persons with any respiratory problems should not perform clean-up or be in the clean-up area. Children and pets should not be allowed access. Soiled curtains, clothing, linens and any other washable materials should be removed and cleaned. Badly mildewed carpets, furnishings and books will probably need to be thrown out.

Water, and mushroom spores. You may have an old tank that is not lined. This could cause condensation from the tank to drip onto the floor or soak into the wall. A new styrofoam lined tank installed by someone who knows what they are doing will eliminate or greatly reduce condensation troubles. It could also be a leaky toilet line or toilet line connection. In this case tighten the flange on the part of the line that goes into the bottom of the toilet tank.If it still is drippy or leaking then get a new toilet water supply line put in. It could also be a leaky tank mount bolt hole. If that is the case then someone who knows what they are doing needs to remove the old tank bolts and seals and replace them with new ones. Another cause could be a bad toilet seal that is allowing water to seep from the toilet to the floor and wall. In this case the toilet would need to be lifted and a new wax or rubber seal installed. You could also have a dripping/faulty shut off valve which would need to be changed. I would get a plumber to check it out. None of these fixes are that expensive. Especially compared to fixing water damage which will only get worse the longer you wait. One other thing make sure you guys aim well so as not to feed the mushrooms;)

Can you elaborate on what the mushrooms look like? Color and size?

I would freak if I found them growing in my house too.

I left a rental place that had huge black mold in the walls. They found it after I left. Professionals cleaned it out. My neighbor said it smelled like a septic system. The pipes were leaking in my 100 year old apt. that I rented. I reported the walls were bulging but landlord was not interested. He sold it and the new one had a large expense in repairs.

Good luck! I starred this to see the best answer.

Clean it with bleach and figure out where the moisture is coming from – Both mold & mushrooms need lots of moisture to grow.

Just FYI – Just because the mold is black, does not mean it is the dreaded “black mold” – True black mold is a specific strain of mold, but several others are black in color as well.

Get rid of it any way you can!

That’s extremely unhealthy, especially with a baby in the house!

Is it coming from the bottom? Maybe it’s molding underneath the tiles? In that case you might have to rip out the toilet can replace where the damage is.

I would use bleach! Bleach the **** out of it.

There is a lot of rotted wood behind the wall there. It is being supplied with water that is escaping the plumbing probably. The wall needs to be opened up and the wood replaced and the leak fixed.

Pour salt directly on mushroom. It should kill it and then clean with bleach. Hope this was helpful.

EW! i think i would never go to the bathroom there again. Use bleach and get a mold removal spray protections products at the local store! (help local stores stay in business!)

STILL GROSS!
