The young lady I spoke to on the phone was extremely kind and informative. Any question I had she could answer. She represents the company extremely well! We need more people like her.

Very disappointed with how 5 micron left my walls and building agree inspection Usually a company would take carpet up in the corner of the room they did it right in the middle 47 cuts and slashes Gave them a chance to make repairs - they refused Be careful when using them and always have someone who knows what they are doing onsite Refused to fix any of it Costing me thousands- they said the building was going to be completely renovated - reason for sloppy job but I never told them that

5 microns was so easy to work with. Absolutely loved Carole! She was so through and educating, a true pleasure to work. I was happy to give them a call and request her to come back for mold clearance.

On time smart great explanations. These folks know their stuff. Kind and don't make you feel stupid. General inspector and real estate agent very impressed as well. Can't go wrong with these guys. Bit expensive but you get what you pay for here.

⭐️⭐️⭐️⭐️⭐️ I had some concerns for mold in my office after gone through some water damage a year back, and I contacted 5 microns, and they came in the following day and ran all the necessary tests. A couple days later they emailed my results with the breakdown of everything I needed to know and how to take care of my concerns! Pascal was also very professional! Highly recommend!

Pascal was very professional and attentive to our needs. He was also empathetic to our situation. He took quite a bit of time explaining things to us. The report is very detailed and professional too. Thanks 5 Microns
mold testing near me

Get mold testing and inspection for your home or business. Professional experts perform them, and free estimates and results are available within 24 hours.

Don’t put yourself and your loved ones at risk of mold exposure, and save yourselves the trip to a lab; let our experts come to you and perform all the work. We have the right equipment, tools, and expertise to complete all the actions at an affordable price. Our job is guaranteed, and we provide a comprehensive service report.

Home mold testing

Mold in building materials can sometimes be seen or smelled. Using a Bio-Pump Plus, our inspectors will conduct an indoor and outdoor test for comparison. The inspector will also collect a tape lift sample for visible mold and perform a moisture level test. Our inspector takes photographs, documents each sample he receives, and completes a chain of custody form. The inspector will draw a map indicating where the samples were collected and return the samples with the chain of custody form to the lab for evaluation.

Results take anywhere from 24 hours to five business days to deliver to you, and it takes anywhere from half an hour to one hour to complete the mold inspection of a home.

Mold air testing

5 Microns Inc. offers mold air testing using a mechanical or electric pump with an attached mold trap. Air testing using the above devices allows us to gather more information about the types and species of mold spores and their levels.

Mold Testing Cost

Residential: Mold Testing And Inspection:

The limited mold service call is from $551 (for up to two rooms) and from $725 for a complete mold inspection (checking every room, including the crawl space, attic, as well as the exterior of the home). *Any inspection of a crawl space requires the presence of an individual who will be present directly outside of the crawl space during the entire inspection by the inspector entering the area to provide help in case of an emergency. Each plan includes three samples, an inspection, and a full report. Each additional sample is $70, whether a surface or air sample. Please note that in cases where we take air samples, one air sample is required on the exterior for the baseline. A baseline is needed because mold spores are not visible and are part of our ecosystem. Still, mold spores enter your building, and a baseline sample is required to compare the interior levels to the exterior. The final cost will be determined based on your location from our office. The number and type of additional samples you will need will be determined during the inspection, and the inspector will advise you and get your permission before taking more samples.

Our inspector will visually inspect using a moisture reader, an infrared camera, and a relative humidity meter. Our inspector will look for conditions conducive to mold, such as water damage and intrusion, among other causes of mold growth.

You will be billed by email once the data is ready. The information will be available in 3-5 business days(not including weekends). The invoice will have payment options for you to choose from. Our office will forward your report after we’ve received payment.

*NOTE: When shopping for mold testing and inspection services, please beware of the free services that mold remediation contractors typically offer. Mold remediation contractors are mainly trained to remove mold from your building; their inspection focuses on finding and remediating visually apparent mold growth. Still, they are not trained to perform comprehensive mold and air quality inspections, which is essential to ascertain the source of the problem and overall conditions. The mold inspection and testing should be performed by a professional (IEP) indoor environment professional who will produce a report that will aid and guide the remediation team in resolving the problem and preventing the issue from returning. Mold remediation contractors and mold inspectors (aka indoor environment professionals) perform entirely different disciplines but often work together on fungal growth problems to achieve the desired results for the client.

*Please note: The final cost will be determined based on your location from our office.

Prices are subject to change without notice, and bids are valid for 30 days from receipt. All prices include complete reports.

Timing for mold testing

The standard turnaround time for results is 3-5 business days (not including Saturday and Sunday) if delivered to the lab by 2:00 pm; otherwise, the clock starts the next day. We offer next-day service.

Same-day mold testing

Samples must be received by 9 am for same-day mold testing results. Call for a quote for same-day results.

Payment

We accept all major credit cards and ACH through your bank account. Once your report is ready, you will be billed via email, and your information will be delivered by email after payment.
