There is mold growing on the insulation in my basement.

The insulation has plastic sheet over it. How do I clean the mold?

Remove and discard the plastic and insulation.

Then if any mold remains it can be removed with soap and water.

Then see this for how to do it correctly.

If you have mold in your basement it could be an indication of a water problem, what I mean is water that gets inside your concrete foundation walls and can't get out. Sometimes when it builds itself up enough it will force itself into basement. If you have ever had water during heavy rain storms it is likely the water that gets trapped in wall is causing the moisture problem - causing mold problem. The mold will continue to re-appear after cleaning it if the water inside the walls remains. If you do have mold b/c of what I've explained the way to fix it is to get the water out of the walls. In order to do so a water-management system is needed which will relieve the hydrostatic pressure built-up against the wall and pressure that may exist from floor also. A dual pressure relief system. Many waterproofing contractors offer free inspections and can tell you if you have mold b/c of a below ground water problem, after looking at your entire foundation. Hope this makes sense to you and helps in some way.

you kidding?

if he or anyone else on this planet has water entering a block wall THROUGH crack(s) or other outside openings(loose parging etc) then the OUTSIDE of THAT-area needs to be waterproof and backfilled correctly.

Then, IF water has built-up INSIDE the cells of the blocks all they have to do is drill some holes in blocks to allow the water OUT and then seal those holes.

Water can build-up Inside the cores of block wall but when it does, its because water IS GETTING IN from OUTSIDE.

They do NOT NEED ANY Interior System, period, end of story! Get the FACTS right please.

Sooner or later, those advertising these FALSE CLAIMS are going to get a call/visit from their states ATTY GEN, believe that. To bllchtttt/scheme homeowners into things they do NOT need for SELF GAIN and is a crime!

Thats right, many-not all companies who ONLY or RATHER install these inside systems purposely misinform/MISREPRESENT `n Falsify claims to get into homeowners bank accounts, dang right.

Hydrostatic pressure against basement walls is RELIEVED/LESSENED by digging up exterior to footing, hauling soil away, waterproofing the dang wall and backfilling with gravel/peastone, sand if one has to.

Hydrostatic-pressure is....

2nd para.. "Many soils absorb vast-quantities of water and this added water, COMBINED with the SOIL, pushes-against your foundation wall. THIS FORCE is COMMONLY referred to as HYDROSTATIC PRESSURE"

READ what these people tell you what is the MOST SUCCESSFUL REPAIR METHOD, cracks,bowed basement walls. What do THEY tell you to backfill with,huh?

2nd para.. Hydrostatic pressure against a basement wall IS....when the SOIL gets SATURATED.

in order to RELIEVE/LESSEN this hydrostatic-soil-pressure AND, take off any-other-WEIGHT/force off outside of wall like tree roots etc is to GET RID of the SOIL,roots etc!

Then 'waterproof' the dang wall correctly, NOT damproof it.

Then backfill carefully/not with a backhoe with most/all gravel! If you can`t get yer hands on gravel/peastone for some reason then use sand.

Larry`s Q) contractors have suggested that i DON`T need to seal the EXTERIOR of blocks, i should just place drains on the inside.....

ANSWER) "You`ve got to stop the water from coming in--any amount is too much.Alot of contractors tell you that you can use an Interior weeping system, usually because its LESS WORK (and less expensive...NOT TRUE in MOST CASES) than excavating around the basement and sealing from the outside. I prefer to seal the EXTERIOR of blocks.Period"

What do THEY also say?

"Basement Walls MUST be sealed to..(AHEM)..PREVENT water intrusion"

Mold can be dangerous and adding water to mold only feeds it. So, if the area is not properly cleaned, you will be adding to the problem.

Please do not offer advise people to use soap and water.

"Basic Mold Cleanup

The key to mold control is moisture control. It is important to dry water damaged areas and items within 24-48 hours to prevent mold growth. If mold is a problem in your home, clean up the mold and get rid of the excess water or moisture. Fix leaky plumbing or other sources of water. Wash mold off hard surfaces with detergent and water, and dry completely. Absorbent materials (such as ceiling tiles & carpet) that become moldy may have to be replaced."

Bill,

With all due respect, all situations are different and while detergent will clean and area, it will not kill the mold. There is a difference between cleaning and sanitizing. If you do not kill the mold, you can spread the mold. Simply wiping down an area WILL NOT remove all of the spores from the surface. Any items used in the process should be thrown away if it cannot be properly sanitized. Also, if you have mold forming in the basement, there are spores in the air which will want to find new sources of food. So, if you do not treat the air as well as the surfaces, the chances of the mold returning at some point are high, not to mention it can be spread to other areas of the house.

Here area possible scenerios to consider by washing an area with water and detergent.

1. Since mold is not killed by detergents, you will feed the mold with water.

2. Any water droplets that reach the floor will now contain active mold spores where they can grow, or you can step on it and track it to other areas of the house.

3. If is sponge/rag is used, now the sponge is infected. If this sponge is put under your sink, there is a risk of cross contamination to other items under your sink.

4. If a water pail is used to rinse the rag/sponge, now the bucket can be infected.

5. if you don't use gloves, the mold spores can lodge under your fingernails. Then if you touch your eyes, ears, nose or other areas of the body you can become infected.

I'm not trying to scare anyone, but these are real world concerns that are well documented.

You can never be too careful when it comes to dealing with mold and your health.

Education is the key.

There are thousand of things in the house that are food for mold.

And there are spores in the air everywhere.

Mold is not caused just by a spore falling on somethig that is food.

It needs MOISTURE.

MOISTURE control is the important thing.
