"This is my first time leaving a review for a company as I've never felt the need to, but using Pacific Environmental I feel I should share with my home owners. My husband and I bought out first home which we love but a room had acoustic ceiling. I reach out to PEAS, which everyone in the office was very helpful and patient on guiding me through this experience. Their scheduling was amazing as I was dealing with Closing Escrow and moving my family in. Once they arrived, they informed me on the scope of work and what they would be doing and what to expect, this being my 8-year-old son room so I was a bit worried on hazardous material that was being removed and used. CONTAINMENT WAS AMAZING! I was so happy and felt so safe on how they kept the area and the protection they took to take care of my family and themselves. My kids thought the crew looked pretty cool too, haha. CLEANING WAS AMAZING! Work was conducted upstairs and they went the extra mile and cleaned everything they touched, I really appreciate that, as it again made me feel secure and safe. PEAS left a memorial memory our kids still talk about. I strongly recommend them and would use them again."

Mold Testing and Remediation questions, answered by experts

Several factors contribute to the persistent growth of mold in vents, with excess moisture being the most common culprit. Consistent mold formation in vents indicates an ongoing moisture problem within the HVAC system or its surroundings, likely caused by condensation on cool surfaces in areas with high humidity. Moisture accumulation can also result from leaks in ductwork, inadequate ventilation, or insufficient insulation, creating an environment favorable for mold growth. Regular inspections, addressing potential sources of moisture, maintaining proper ventilation, and routine HVAC maintenance can help prevent the recurrence of mold in vents. If the issue persists, seek professional assistance to identify and rectify the underlying problems.

Inhaling black mold spores, even from behind walls, can cause people to have a wide variety of potential health issues. Some people may only notice a few breathing problems, while others can become quite sick with symptoms related to severe allergies. Constant exposure to mold spores can lead to lung infections and other long-term health problems. If you believe you have black mold inside your walls, you will want to reach out to a pro for an inspection and for advice on how to take care of the problem before it causes severe illness.

Toxic mold doesn't have a specific color; instead, toxicity depends on the type of mold and the mycotoxins it produces. Stachybotrys chartarum (also known as black mold) is notorious for its potential toxicity. However, not all molds appearing black are Stachybotrys chartarum. Mold species that appear in various colors, such as green, gray, brown, or black, can also produce mycotoxins. Therefore, it's essential to focus on identifying the type of mold through professional testing rather than relying solely on color to determine its toxicity.

The four types of hazardous waste are toxic, corrosive, flammable, and reactive. These four types fall under the EPA’s designation of characteristic hazardous waste. The EPA also categorizes hazardous wastes as listed, which includes specific byproducts or unused chemicals from manufacturing and industrial processes, universal waste, including bulbs, mercury, pesticides, batteries, and various other common substances, and mixed waste containing radioactive material.

Several factors affect the color of mold, including humidity levels, age of the mold, and amount of light it receives. A patch of mold that starts out green may darken and turn black as it ages. A species of mold may be green if growing in one environment, but be black in another environment. Color usually isn't a reliable way to determine mold species or risk.
