"All work was completed on time with exceptionally high-quality work. All workers were introduced to me, making me comfortable with strangers in my home. All workers wore masks and used all health recommendations. I was brought into every step of the process and the process was explained. The total cost was as estimated. The price was about half of the estimate of other contractors. I was very satisfied. I recommend this business."

"Larry answered my call and explained why we have no need to remediate what was safe in its present condition, notwithstanding the re-roofing we are about to perform on the house. In other words, although he could have suggested we engage him for some remediation work for which I apparently would have had no need, he was honest and talked me out of paying for something I did not need. Class act."

"We discovered we had mold in our home after we had a leak. Matt and his team tested our home for mold, then we completed the dry fog remediation treatment. They gave me post tests to show the mold has all been killed. They were very thorough everything went just as planned. Excellent job, I am very impressed!"

"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

Mold in HVAC ducts is a relatively common issue that homeowners struggle with—especially in humid climates or homes with poor ventilation. Moisture from condensation, combined with dust and organic debris, creates the perfect environment for mold growth. Homes with high humidity, leaky ducts, or clogged drains are more prone to this issue. Regular inspections and proper HVAC maintenance significantly reduce the risk of mold developing in your ducts.

If you’re wondering which is more toxic, laminate vs.vinyl flooring, you might be surprised to learn that both can include toxic chemicals. Depending on the specific brand and the manufacturing process, both are likely made from synthetic materials that can emit volatile organic compounds, or VOCs, into the air. However, since laminate has a wood core, it is more sustainable and less polluting than vinyl, which is entirely synthetic and almost always emits more VOCs than laminate flooring. If you’re concerned about indoor air quality, choose a low-chemical flooring manufacturer or, better yet, choose flooring that doesn’t off-gas VOCs.

Black mold and wood rot are both types of fungi that thrive in damp areas, but they are distinct issues with different consequences. Wood rot specifically refers to the decay of wood caused by fungi, which compromises the wood's structural integrity. Black mold, on the other hand, is a fungus that grows on the surface of materials, including both rotting and non-rotting wood. The primary difference is their impact: wood rot affects the wood's structure, while toxic black mold is a health hazard. Inhaling black mold spores can cause severe respiratory issues, whereas wood rot spores are generally not harmful to people. Because mold can grow on rotting wood, the two issues can be interconnected, but they are not the same.

Services test for allergens, mold, VOCs, and carbon monoxide levels to ensure a healthy indoor environment.

Mildew is a type of mold that forms in areas of excessive moisture and poor ventilation. Although it commonly exists in household air, it can’t take hold and spread if a surface is clean and dry. Generally, if you have any mildew or mold issues, it’s because the humidity in either your house, room, cabinet, or cupboard is above 50 percent. Common areas where you’ll find mildew are around water sources, which is why it’s commonly found near showers and in kitchen sinks.
