"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."

"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."

"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

Dead trees are dangerous for several reasons. They are structurally compromised and prone to branch or trunk failure, which can pose a significant safety risk to people, vehicles, and nearby structures. Dead trees can also harbor pests like termites, which may spread to other trees or your home. If a tree died from a disease, it could spread the illness to healthy trees. Additionally, the dry wood is highly flammable, increasing fire risk.

Mildew and mold are not different—mildew is a specific type of mold and yes, it can become dangerous if left untreated. It would be amazing if we were all biochemists but because we most likely aren’t, it isn’t wise to assume any mold is mildew on sight alone. Harmless mold and toxigenic mold (which can be deadly) look very similar, so if you see any new mold that looks even a little suspect, call a mold professional immediately.

Mold thrives in high-moisture environments, whether that’s steady leaks or just high condensation. Around the house, common causes of mold include leaky pipes, a leaking roof, high humidity, poor ventilation, a damp basement, rotting food in the fridge, wet clothing and towels not hung properly for drying, a leaking foundation, and a leaky air conditioner.

And, of course, if your home suffers from flood damage, you stand the risk of developing mold in the aftermath. That’s why it’s important to act quickly at the first sign of mold.

Yes. Black stains are more than an eyesore. Some black stains can pose health concerns, especially for those with asthma, allergies, or other respiratory conditions. Some stains can also damage the brick’s structural integrity, harming the mortar and resulting in more expensive repairs.

Eliminating mold from wood permanently poses a challenge as the mold spores have the ability to deeply penetrate the porous wood surface. While surface mold can be effectively eradicated with proper cleaning and preventative measures, it's difficult to guarantee its non-recurrence under favorable conditions. To prevent mold from reappearing, it is important to identify and resolve the root cause of the moisture that triggered mold growth initially.

Ensuring appropriate ventilation and a dry environment, or consider applying protective finishes such as sealant, varnish, or paint to prevent future moisture penetration and mold growth. Consistently inspect and maintain the area to keep the wood free from mold in the long term.
