About Same Day Mold Testing

Same Day Mold Testing (SDMT) is an indoor environmental testing company that specializes in mold inspections, testing and consulting. We have the privilege of a 4-star rating on Yelp.

SDMT has been in business since June 2005.

Common Questions

Yes. SDMT inspectors are certified to perform mold inspections by the American Council for Accredited Certification (ACAC). ACAC is a nationally recognized certification organization for the indoor air quality industry. Mold inspectors are not regulated by state or local government. Therefore, licensure is not required in California.

Yes. SDMT carries worker’s compensation and professional liability insurance policies. SDMT liability is limited to the fee for service.

We do not offer ‘ERMI’ Testing. Here’s what the EPA has to say about it: Should I test or sample for mold in my home using the Environmental Relative Moldiness Index, or ERMI? No. The Environmental Relative Moldiness Index, or ERMI, developed by U.S. Environmental Protection Agency researchers, is a research tool and is not recommended for use except as a research tool.

Close doors and windows several hours prior to the inspection. Turn off air purifiers. To ensure indoor air quality is not diluted by outdoor air or ‘cleaned’ with mechanical air purifiers. Remove contents from below sinks to enable viewing of the back wall and cabinetry floorboard.

The average cost of an inspection is $400. Example: Scheduled Initial Inspection and 4 samples with standard rate results: $400 + $400 (4 samples @ $100/ea.): Total: $800.

SDMT provides services for those located in Southern California, spanning from Los Angeles to Palm Springs, San Diego, Santa Barbara and the Antelope Valley. We’ve been as far as Bakersfield too! Contact us to see if we can serve you!

There are several tasks involved with generating a report. These tasks could take an hour or more, and are largely contingent upon the momentum of the inspector while performing office duty. Here’s what’s involved: Photo Review (necessary after the passage of time from the date of inspection), Review Job Notes (specific issues related to the job), Photo Selection (identifying the best photos taken during the inspection, which could total dozens!), Report Prep (data entry, report writing), Insert Photos (mark up photos with captions and labels), Draft Review (ensure completeness and accuracy), Final Draft (Save as PDF File), Email Delivery (lab results and report). NOTE: If any portion of your balance is unpaid, no inspection report will be generated.

Delivery of report depends on turnaround time of lab results. If no samples are collected, we can usually deliver the report same day or next day. It can take up to 10 business days for a written report with standard lab results depending on the field workload and the demands of a ‘same day’ brand. Holidays, weekends, training, illness, termination, technical difficulties, emergency, social constraints and jury duty are excluded from delivery time frames. We recognize the report is an important document and want to get it to you as soon as possible.

There are several types of samples that we can collect. The most frequently collected sample types for mold testing include air, surface, and cavities. Lesser type samples for mold are carpet, bulk materials and personal contents. We can collect paint chip samples to be analyzed for lead hazard. We can also collect bulk samples like acoustic ‘popcorn’ ceiling, insulation material, and other suspected asbestos containing materials.

Samples are collected from the air, wall cavities, bulk material, or from the surface depending on the level of validation sought from the analytical component of the assessment. The per sample testing charge is in addition to the inspection fee. Each job presents its own set of variables that will influence the number of samples recommended. The customer has the discretion to accept or decline sampling recommendations. The lab provides a report of findings. Lab turnaround time starts when the samples are received by the lab. Verbal notification satisfies lab turnaround commitment, which includes call attempted, voice mail, text message and/or email. If the lab is the reason for the delay in communicating lab results, there is no refund of the service fee. Periodically, the lab has to ship out samples to other locations in which case the timer doesn’t begin until the next lab logs the samples for analysis. But they do not discount the cost of sampling because of this inconvenience. Consequently, we do not discount the lab fees.

Our Company Policy is that only the customer/client that paid for the inspection is given documentation or specifics about the inspection. We encourage other interested parties to contact the paying customer or client to obtain specifics about an inspection and/or lab results.
