"I called Alpha Environmental Services on 5/14 to schedule an inspection of my attic for mold. After paying $150 inspection fee, the appointment was made for 5/17. I received an appointment reminder e-mail on 5/16 asking for confirmation that appointment will be kept. Chris arrived on-time on 5/17 and performed the inspection which took about 30-45 minutes. Later that day, Chris forwarded me an e-mail with pictures of attic problem area and bid describing the work to be performed. Chris identified the source of the problem which another mold remediation contractor failed to identify the previous day during that contractor's inspection. I approved the bid and work was scheduled for the following week. A technician arrived on time and completed the repair and remediation within 2 hours. The technician performing the work was friendly, answered all questions posed to him, and cleaned up the work area. I received the final invoice with a post action report detailing what remediation was performed, including pictures of the treated areas via e-mail including Alpha's statement of guarantee the following day. Overall the process was super smooth, very professional and most importantly hassle free. I will be hiring Alpha Environmental Services for all my future mold remediation needs."

"These crawlspace guys showed up and took care of a problem I didn't have any guts to do. My wife smelled a dead animal under the house. We thought it was in the ducting, but the co-owner of the company Dillon came through, crawled in, and after a lot of searching, found the dead rat hiding just above it. He cleared everything out, got everything sealed up again and gave several excellent options to move forward. I can't recommend the crawlspace crew enough if you find you need crawlspace remediation in Portland, Oregon or the surrounding areas."

Biohazard Remediation FAQs, answered by experts

Fumigation performed by licensed exterminators is safer and more effective than store-bought foggers. That’s because there are a lot of harmful substances and risky techniques used during such a service, and using or doing them without sufficient knowledge can put both you and your home in harm’s way. When in doubt, let a pro take care of tasks like this. 

Yes, it is generally unhealthy and can be dangerous to live in a damp basement. The damp air can negatively affect your breathing and lungs, and the moisture promotes mold growth and pest infestations. Inhaling mold spores or waste particles from insects and rodents attracted to the moisture can be hazardous. This damp, moldy air can also circulate into your main living area. It is crucial to resolve any moisture problems and implement preventative measures before using your basement as a living space.

Professionals are trained in identifying hazardous materials and utilize industry-approved methods for safe handling and disposal. They adhere to regulatory frameworks to protect health and the environment, ensuring all materials are disposed of safely and responsibly.

If you notice water accumulating in your vent due to a roof or plumbing leak above your ductwork, it's essential to promptly identify the source of the leak and undertake any required repairs without delay. Such leaks have the potential to swiftly result in water damage within your home, ultimately leading to mold and mildew concerns.

The negatives of a humidifier are the potential for mold growth due to high humidity levels, the up-front cost, and the energy requirements to run it. Depending on the state of humidity in your home, you may not actually see lower utility bills due to the humidifier running on a near-constant basis.
