Mold Remediation Mold Remediation Process Professional mold remediation entails several procedures

When you call SERVPRO of Lexington-Bedford to clean your mold, you can trust that you will be advised by experienced crews. Our technicians are trained and certified to follow the Institute of Inspection Cleaning and Restoration Certification (IICRC) S520 Standard for Professional Mold Remediation.

Mold Remediation Process

There are several steps in the mold remediation process. Not all steps will be necessary in every situation because each outbreak is unique and the response must be tailored to the job.

Asbestos Test

If a mold remediation job will require demolition and removal of materials, we will bring in an asbestos testing company to test materials in accordance with Massachusetts DEP law 310 CMR 7:15 (4). We cannot begin the job until we get the results from this testing.


Depending on the extent of the outbreak, we may need to isolate parts of the building to prevent cross-contamination. Heavy plastic sheeting with zippered closures creates a moisture barrier, and a negative air machine keeps air from escaping the containment zone.

We also have our technicians put on personal protective equipment like gloves, googles, body suits, and masks. This protects them from exposure to the contaminants.


Not all mold jobs will require demolition. However, when porous materials like drywall and carpet are contaminated, they cannot be disinfected and must be removed and discarded. As mentioned above, asbestos testing will be performed before this step to determine the proper handling and disposal of the contaminated building materials.

Microbe Removal

We use a HEPA-filtered vacuum to remove visible microbial growth from structural elements like rafters and support beams and non-porous materials like concrete. Depending on the extent of contamination, we may apply an anti-microbial solution to kill any living mold and then vacuum again to remove dead and decomposing microbes.


We usually finish by applying a botanical anti-microbial product that will discourage future mold growth on all surfaces. We then run a HEPA-filtered air filter machine for a day or two to cycle all the air inside the containment zone through the filter several times and remove as many spores and particulates as possible.

Dry If Needed

If necessary, we set up fans and dehumidifiers to dry the area. Fans speed up the process of pulling water out of building materials into the air, and the dehumidifiers extract the water vapor from the air.

Final Rinse

Some jobs require a final pressure washing of the floors before we leave. We pack up all our machines, clean up behind ourselves and wash the floors if appropriate.

Many Steps

As you can see, there are many steps in the mold remediation process. Not all are necessary for every job, but our production managers are familiar with the protocols and can explain how we plan to complete the job and why we have chosen a particular course of action.

When you find a mold outbreak in your home, consult a professional mold remediation specialist as soon as possible. The sooner we begin removing and remediating, the sooner everyone in the building will be breathing easier. Call 781-861-0500 for a free estimate and let us make it “Like it never even happened.”
