"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."

"We had a leak in our tub that caused significant damage to everything around it. Kevin came out and did a thorough inspection, walked us through what the process was going to look like, and started demo a couple days later. Chris and Garrett primarily worked on our project and had great attitudes, always friendly, and communicated every step of the way. Our bathroom is now put back together and looks great."

"I researched mold inspection companies and read excellent reviews on Craig Cooper the local Mold Inspection Sciences inspector. I met Craig I told him he had a great reputation and I expected him to live up to it. He did and far more. Craig's pre-remediation inspection identified the type of mold. But Craig went beyond that. He is a great teacher and he educated me on the probable cause of the mold, various methods of mold removal, and provided the information I needed to select a remediation company. Brad of the MIS staff was also extremely helpful. I selected a firm that used a remediation method that Craig and Brad had recommended. The work was completed in a timely manner and passed with flying colors."

"I was not able to view the final work as the house had changed ownership by the time the work was completed. But I can say that the technicians that I met were sympathetic regarding the situation, professional, and timely. First of all, compliments to Michael who volunteered to work on his Friday off in an attempt to get work done before the change in ownership took place. Thank you! The remediation took longer than anticipated because additional damage was discovered with the removal of debris and the ownership changed in the interval. But the crew kept to the schedule and successfully worked thru the change of ownership. You are appreciated. Thank you."

"We had an old octopus furnace, covered in asbestos abated, and then removed so a new furnace could be installed. Everyone from the secretary, Diana to Daniel, who supervised the crew, were absolutely the best to work with. Always prompt, always friendly, and answered all of my questions. I highly recommend them!"

Biohazard Remediation questions, answered by experts

Yes, you can save moldy wood furniture by removing the mold as soon as you notice it. Mold can penetrate and damage porous wood, though, so waiting to clean it could lead to significant damage. If a large coverage area of mold grows over several months, you may want to ask a professional to try to save the piece. If the damage is bad enough, though, even a pro might not be able to save it.

While water in your basement is unlikely to make you sick unless it’s coming from a sewage backup, mold is likely to start to grow in wet areas within 24 hours, and mold can make you sick. According to the Centers for Disease Control and Prevention (CDC), inhaling mold spores can cause allergy symptoms, including runny nose, itchy eyes, difficulty breathing, wheezing, and itchy skin. Individuals with pre-existing respiratory issues like asthma and immunocompromised individuals are at an elevated risk of symptoms when inhaling mold spores.

Includes cleaning, removal of contaminated materials, and air filtration.

It is not advisable to shower in a bathroom contaminated with black mold due to the potential health hazards it poses. Inhaling mold spores during showering can trigger allergic reactions, respiratory issues, and skin irritations, especially for individuals with pre-existing allergies or respiratory conditions. Prolonged exposure to black mold can result in severe health complications. It is crucial to eliminate any black mold problems in your bathroom before continuing with showering to ensure a safe and healthy environment.

Mold is a blight on your home but over time, can be an extreme health risk, especially for immunocompromised individuals. Depending on the type of mold you’re dealing with, you could even experience neurological symptoms, or in extreme cases, you can be hospitalized. Even a tiny speck of toxigenic mold can cause a whole slew of very serious health issues. Deal with any mold issues immediately.
