Black Stachybotrys Mold Growth on Sheetrocked Ceiling

Mold Remediation Procedures ::

1) Containment:  We set-up a proper containment area to prevent the spreading of mold spores from the contaminated work area to non-target areas. Then, a heppa filtered air scrubbing machine is installed to remove air-born mold spores during the mold removal procedures. This is most important when performing basement mold remediation, or when performing mold remediation to inside living areas of the house.

2) Removing the Mold Contaminated Materials:  Removing the Mold Contaminated Materials: We then remove and dispose of all porous, contaminated materials. I.E. Sheetrock, wall and ceiling insulation and carpeting.
Note: A common place we perform mold remediation, other than to an attic ceiling
or bathroom, is to a basement for grey or black mold removal. Black mold growth found in a wet basement is frequently the most toxic type of mold we remediate. Its called stachybotrys mold. Its usually a solid black color and needs very high moisture levels (like a past flood) to get established.

It prefers to grow on cellulose materials that got wet; i.e. sheetrock walls.
Another common basement mold is called aspergillus. Its found in damp basements with a humidity level above 60% growing on walls, ceilings and stored items on, or near the floor. Aspergillus mold growth can look either white, grey or charcoal colored. This is usually a medium toxicity type of mold.
 

3) Killing and Cleaning the Mold:  Then, our Mold Remediation Technology is applied by trained, professional technicians. We'll clean the mold with an EPA registered moldicide/cleaner/sanitizer/ disinfectant specifically formulated for mold remediation that will kill all surface molds. We then perform an additional 3 steps that many mold remediation companies skip.

4) Removing the Mold Stains:  We'll apply a very specialized mold stain remover that will remove the remaining deep mold stains.  This is most important when performing mold remediation to exposed attic ceiling wood. To read why, see our Attic Mold Page.

5) Fungicide:  We'll then treat the wall and or, ceiling materials with an environmentally friendly solution from the mineral family that is designed to penetrate deeper into the wood to kill the mold roots (hyphae) and prevent mold re-growth. 

6) Sealer:  A long lasting anti-microbial encapsulant sealant can also be applied. We use different types of mold remediation sealers for various areas and materials. After the application of our sealer we can warranty the treated materials against future mold re-growth.

                    

          
Note:  We use a clear anti-microbial sealer 99% of the time. Before we can use a clear sealer, we need to get the cleaned and treated  wood surfaces looking clean & mold free. Some companies routinely apply a white sealer to cover up a poorly cleaned attic ceiling. When they do this the white sealer will start peeling within a few years where it was applied over the remaining moldy areas. This leads to a very difficult and expensive redo. Also, the white sealer on the attic ceiling sends out a red flag to any future home inspectors.

Note: We also offer CO2 dry-ice blast cleaning for mold removal. This is a preferred method for mold remediation around chemically sensitive occupants. It is also often used during the cold winter periods because there is no need to wait for the initial treatments to dry before applying any sealers.

See - Dry-Ice Blasting Page

Note: Mold remediation is very case specific. Our treatments are tailored to the unique situation of each property. Sometimes elderly or sick people can't leave the premises. Some basements have flooding or moisture problems. Some attics have ventilation problems or ice dams. All these conditions will need to be considered before a proper mold remediation plan can be written.

Post-Testing ::

Is it gone?   How do I know?   After a mold remediation job has been completed, our company can perform additional mold testing to the treated areas in the environment where the risks were identified and a mold removal procedure was performed. These can be either indoor air testing or direct sample re-testing of remediated materials. All samples are sent to an independent 3rd party laboratory for analysis. Data analysis from these new culture surveys is made available to the client on a confidential basis. At that point we can provide a scientific-based before and after evaluation of our work to demonstrate and to provide assurance that the building is safe.

Prevention ::

How can I stop mold from returning after I have had a mold remediation treatment performed?   Find the water intrusion source(s) and correct them.

          

          If the mold problem was in the basement:

 

Make sure gutters take roof water at least 8 ft. away from exterior foundation

        Seal any foundation or basement floor cracks

Cover dirt crawlspaces with poly

        Run a de-humidifier set at 50% or lower

If the mold problem was in the attic:

        Check the attic roof for leaks after a heavy rain
        Prevent winter ice dams on roof
        Make sure upstairs bathroom is venting outside - not inside attic
        Check to see if there is adequate lower soffit vent openings
        Make sure the soffit vents are not covered with floor insulation
        Homes should have proper ridge venting on the attic peak
