Guide to Mold Cleanup After Disasters
Cleaning up after a ﬂood can pose health risks. You, your family, coworkers, or employees should wait to re-enter the property until Envirogyn and other Professionals tell you it is safe, with no structural, electrical or other hazards.
Before you start cleanup activities, contact your insurance company and take pictures of the property and your belongings. Remember – drying your property and removing water-damaged items is your most important step for preventing mold damage.
Is there a Problem?
Was your property ﬂooded? If so, and you were not able to dry your property (including furniture and other items) within 24-48 hours, you should assume you have mold growth. You need to completely dry everything, clean up the mold, and make sure you don’t still have a moisture problem.
You may see or smell mold on clothing, drywall, furniture, cardboard boxes, or books, but it may also be hidden under or behind items like carpet, cushions, or walls.
Mold Basics: How Molds Can Affect Your Health
Exposure to mold can lead to asthma attacks, eye and skin irritation, and allergic reactions. It can lead to severe infections in people with weakened immune systems. Avoid contaminated buildings and contaminated water as much as you can.
Flood water may have carried sewage or chemicals into your property. This could expose you or your family to viruses, bacteria, disease carriers (such as mosquitos), and parasites, as well as mold.

You can protect yourself and your family from mold exposure by following these steps.
- Wear personal protective equipment. Wear an N-95 respirator at a minimum, goggles, and protective gloves.
- Use portable generators carefully, outside and away from the home, to avoid carbon monoxide poisoning and fires.
- Ensure the mold cleanup is complete before reoccupying your home.
Before You Enter Any Mold Site:
- Protect yourself and loved ones against hazards. People with breathing problems like asthma or who have weakened immune systems should stay away from moldy sites. Children should not take part in disaster cleanup work. Check for loose power lines or gas leaks. Make sure the electricity and gas are turned off. Look for sagging ceilings or ﬂoors or other structural problems. Watch out for wet, muddy, or slippery ﬂoors.
- Protect your mouth and nose against breathing in mold: wear at least an N-95 respirator. If you plan to spend a lot of time removing moldy belongings or doing work like ripping out moldy drywall, wear a half-face or full-face respirator. Basic information on using it is in OSHA’s general respiratory protection guidance.
- Protect your skin. Wear protective gloves (non-latex, vinyl, nitrile, or rubber). Do not touch mold or moldy items with bare hands.
- Protect your eyes. Wear goggles that provide complete eye protection. Choose goggles designed to keep out dust and small particles. Safety glasses or goggles that have open vent holes will not protect you against dust and small particles.
After You Leave A Mold Site:
Protect yourself and loved ones. Shower and change your clothes. This will help you avoid carrying mold and other hazards back to your current living quarters.
Should I Do This Myself?
This job may be too difﬁcult or dangerous for you. It may be best to get help from experienced and qualiﬁed professionals if you can. Hire Envirogyn to inspect, report, and recommended the damaged parts of your property. Texas does regulate mold remediation.
Sampling for mold is not usually recommended. Understanding the results can be difﬁcult, and no matter what kind of mold is in your property, you need to clean it up and ﬁx the moisture problem.
If I must do this myself, how can I do it safely?
Follow these steps:
- Put on the personal protective equipment described above to protect your eyes, nose, mouth, and skin.
- Remove standing water and wet materials. Use a wet vacuum to remove water from ﬂoors, carpets, and hard surfaces. Dry your property and everything in it as quickly as you can within 24 to 48 hours if you can.
- Open all doors and windows when you are working and leave as many open as is safe when you leave. Open inside doors, especially closets and interior rooms, to let air ﬂow to all areas. Take doors off their hinges if you need to. Open kitchen cabinets and bathroom vanity doors; remove drawers, wipe them clean, and stack them to dry. Open the attic access to let air ﬂow to the attic. Before you open the attic door, make sure nothing will fall on you.
- When electricity is safe to use, use fans and dehumidiﬁers to remove moisture. Do not use fans if mold has already started to grow, because the fans may spread the mold.
5. Clean with water and a detergent. Remove all mold you can see. Dry right away.
6. If you use cleaning products, do not mix cleaning products together. DO NOT mix bleach and ammonia because it can create toxic vapors.
7. Painting or caulking over mold will not prevent mold from growing. Fix the water problem completely and clean up all the mold before you paint or caulk.
8. Throw away items that can’t be cleaned and dried. Throw away anything that was wet with ﬂood water and can’t be cleaned and dried completely within 24 to 48 hours. If you have precious items that you want to preserve, follow these guidelines from the Smithsonian Institute: http://www.si.edu/mci/english/learn_more/taking_care/mnm.html
Safety Tips on Using Portable Generators
If you use a portable generator for electricity use CAUTION to avoid carbon monoxide poisoning and ﬁres.
- Use portable generators OUTSIDE and at least 20 feet away from buildings.
- Do not use portable generators inside your house or garage.
- Do not put portable generators on balconies or near doors, vents, or windows.
- Do not use portable generators near where you or your children are sleeping.
- Never refuel a generator while it is hot.

Am I Done?
If you still see or smell mold, you have more work to do. After a remediation, there should be no signs of water damage or mold growth.
- You may need to ask a mold remediation professional to know whether your mold problem is completely ﬁxed. As noted in the “Should I do this myself?” section, sampling for mold is not usually recommended; instead, a careful inspection of the work area for completion of the cleanup and absence of mold-related odors is usually appropriate.
- If you have health problems that get worse when you return home, like asthma or allergy attacks or skin or eye irritation, you may still have some mold.
