Answer Questions

What type of walls do you have in your basement? Sheetrock and studs most likely need to be removed if they're moldy, but block walls can be cleaned with a hard (dry) brush, bleached and quickly dried. There are also many mold cleaners available at your local hardware store--including some green options. (Be sure to wear a mask and ventillate the area if you're going to attempt a DIY. Hiring a mold removal specialist is also an option.)

To keep the mold from returning, you'll need to find out where the moisture and dampness is coming from. Have a dehumidifier on hand and be sure to properly vent the area and increase air flow if possible.

I believe you can also get paint that will prevent the spread of mold.

As previous answer stated...find the moisture problem and you will solve your mold problem. Find a contractor that has experience dealing with below grade moisture issues and have them try to determine the cause of the moisture and what some remedes might be. This can be a very complicated issue or one that is as simple as deverting the water away from your house with gutters. Best of luck with finding the resolution!!

You may need to remove drywall and insulation - studs only if they are rotten. You will obviously want to stop future leaks so repair the foundation if it's cracked, get a battery backup on your sump pump, or repair the leak by the roof or window that's leaking. Once the cause has been fixed, you need to stop the mold. Bleach diluted with water and sprayed can take care of most minor mold problems. But if you want to be ultra safe or if you have a lot of mold or potentially dangerous mold, you will want to have a professional company fix it. There are mold remediation companies that charge a lot of money for this. However, I think the most effective treatment is with Ozone, as it will kill all mold and mold spores. You will need a company to do this as well. You also will have to leave your home (with all pets) for at least 24 hours, as the ozone is toxic to breathe.

1. Correct Moisture Problem
2. Install dehumidifier to reduce RH (relative humidity) to a level below 55%
3. Set up / operate negative air machine (hire contractor or rent a unit short term)
4. Seal any floor vents or duct work leading into living space
5. REMOVE ALL SHEETROCK AND INSULATION (if you have any)
6. Sand infected areas lightly
7. Spray apply biocide (or lysol concentrate) to all lumber surfaces (upper floor joists and subfloor)
8. Allow 48 hours dry time (RH should once again come down under 55%)
9. Spray apply a good mold inhibitor (olympic makes a good product for this)
10. install new R 19 insulation (if there was any)
11. call a local inspector or remediation company for an air test to insure you have dealt with the problem correctly.
BY ALL MEANS DO NOT USE CLOROX OR BLEACH, IT WILL ENHANCE YOUR PROBLEM DRAMATICLY
Good Luck

You have to get rid of the moisture proublem, buy fixing the water from coming into the basement, or fixing the moisture problem, or leak that has accured in the basement, this is never a quick fix unless you have a leaking drain line, leaking water pipe, hvac drain stoped up or bad pan and in some cases it could even be coming from a roof leak that has not shown up in the home.

Mold in a basement is a common problem. My company helps people with this every day. Some of the answers you received were helpful but not all the information is correct. First, you need to eliminate the two main ingrediants that mold needs to survive. The first one is water intrusion. This is a must. I am assuming you have no water intrusion as you make no mention. The second componant that needs to be eliminated is moisture. Moisture is also humidity. Basements need to be kept airtight in the summer months. Some folks have posted that you need air flow in your basement. Nothing could be furthur from the truth. When you open any windows for example, not one micron of air goes out of the basement, Warm humid air is sucked into the basement. Houses suck air into the basement and it meets the cool surfaces and skyrockets humidity. The windows must be kept closed and a dehumidification device installed to ensure humidity stays below 60% humidity. The dehumidifier should be energy star rated and purchasing a seperate humidity guage is a must to monitor the unit's progress. We like to keep our customer's basements at 50% humidity. This eliminates the smell that is active mold spore growth. Once the water and humidity is brought under control. Remove the organic materials that have mold on them. Walls, sheetrock and studs that have been affected. Follow the advice of previous posts as you must ensure that you do not affect the rest of the home. Once removed, install new walls using as much inorganic material as possible. We also install vapor barrier over the walls and seal the floors to stopwater vapor transmission into the basement. Poly plastic is not a acceptable vapor barrier. It is not "zero-perm" and will still allow moisture transmission. It will also crack and break into pieces over the years. A PVC liner rated "zero-perm" is the correct product in this application. Depending how large the basement is and if it is sectioned off will determine the dehumidifier strength. We use the Santa Fe line of dehidifiers as they are super energy efficiant and work like a dehumidifier on steriods. I hope this helps and I wish you the best in Basement Health!

The bast way to get rid of mold it just use blich 1 : 10 ratio (1 blich + water) all pros use it . Save money and use it . sometime I use 50% +50% Do NOT forget Gloves. $5.00 on materials and spray bottle solve your problems.
