"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."

"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, many professional cleaning services include mold and mildew removal using safe, non-toxic solutions.

Disposing of old paint, bleach, oil, and fertilizer should be handled by a company that specializes in this kind of waste. Many private junk removal companies do not dispose of these items. Because these materials are hazardous to the environment and dangerous to handle or dispose of improperly, you should confirm with your local municipality about places to take hazardous materials for safe disposal. 

Bleach will kill green and black types of mold, but isn't always the best choice. Vinegar can be a more effective mold killer, as it can penetrate surfaces, killing mold beneath. If you have a large area of mold, it's best to hire a mold remediation company to take on mold removal.

Yes, outside leaks can easily cause damage to your home if you don’t have waterproofing measures in place. Regularly check your property for signs of a leak, ensure your home’s landscaping is at least at a 5% slope, your basement windows are sealed, and you have an aligned gutter system to catch rainwater.

If you find black residue in your toilet tank, chances are it’s caused by manganese deposits from hard water and not mold growth. You can prevent these deposits from damaging your toilet by installing a water softener in your home, which also might improve the quality of your drinking water. You can also remove the deposits inside your toilet tank once every six months or so to prevent them from causing problems with toilet functionality.
