"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."

"Ongoing water intrusion from our windows over the years led to mold issues throughout several rooms in the house. After bringing out three different companies to evaluate the situation, Steven and the team at Nexgen Property Restoration stood out right away. They were fair on pricing and offered a non insurance discount since we chose to handle everything out of pocket. With multiple areas needing to be opened up, that savings really helped. The remediation process was handled professionally from start to finish and the quality of work gave us the confidence to move forward with them for reconstruction as well. Having one company manage everything made the process a lot easier. The final result came out great and their warranty gives us peace of mind moving forward. Definitely recommend Nexgen if you?re dealing with paying out of pocket"

"SavOn/Ivan came out immediately and tested the area in question. I had mold in my dining room ceiling, not airborne thank God; but mold none the less needing remediation. SavOn completed the remediation in about 4 days and were very thorough, professional and attentive. Taylor in the office and Ivan in the field provided excellent service. SavOn was a little pricey but not as astronomical as the other companies. My project is not yet completed due to a lack of funds on my part but the cosmetic repairs will be completed soon and I'll keep you posted on the progress. Angel A"

Hiring a professional for mold and toxic material testing ensures precise identification of harmful substances within a home. Professionals utilize specialized equipment and techniques, providing accurate results that inform proper removal strategies, safeguarding occupant health.

It is safe to remove old linoleum, but it may require the help of a specialist due to the risk of asbestos in the material. Before you cut into linoleum or try to peel it up, have it tested for asbestos. If it tests positive, professionals will need to remove it to prevent the risk of health issues from airborne toxic particles. If it’s asbestos-free, DIY removal is possible and safe.

Black discoloration on your attic insulation may be caused by buildup from soot, dust, or dirt, which does not come with dampness or a musty odor. However, another cause of black discoloration on attic insulation is black mold, which has a musty smell and other signs of damage. If you’re unsure what black stuff you’re looking at, consult a pro to be safe.

White mold is generally considered less harmful than black mold, which can be more toxic due to the mycotoxins it produces. However, white mold can still be harmful, particularly for individuals with mold allergies, asthma, or other respiratory conditions. Exposure can cause symptoms like nasal stuffiness, throat irritation, coughing, or skin irritation, and it can exacerbate existing health issues. Because any type of mold can pose health risks, all mold infestations should be treated seriously. Prompt remediation is necessary, and you should take proper precautions, such as wearing protective gear and using appropriate cleaning agents, when dealing with it.

Yes, mold under silicone caulk can potentially cause health issues, which may be more noticeable in people with asthma, allergies, or other respiratory conditions.
