"We were happy to find Tommy and his crew. We had some water damage in the lower level of our home after the heavy rains this year. We had mold in the carpet and water coming in through the porous tile. Tommy gave us a fair quote and their staff handled the process professionally. There were no surprise charges and the crew showed up on time and the office quickly responded to our emails. They did the build back after the mold remediation and we could not be happier with the way it turned out. They did a beautiful job. I highly recommend Pure Restoration if you are dealing with a mold takeover in in your home!"

"On a referral we contacted Baldwin Builders to do asbestos abatement and removal of old air ducts from the attic. Not only were they professional, efficient, and reasonable, but the job was done promptly and they were immaculately clean in the house. I would definitely recommend this company. Hallie was always very helpful."

"We had severe water damage in our home that affected the kitchen, dining room, bathroom, and pantry. Jose and his team came to the rescue and did an exceptional job restoring everything. They worked quickly, stayed organized, and kept the area spotless every day. Jose is incredibly reliable, honest, and easy to communicate with. He always showed up on time, kept his promises, and made sure every part of the job was done right. His crew is skilled, professional, and worked efficiently together. I got three estimates before starting, and Jose not only offered the best price but also finished the job faster than anyone else. The results are clean and beautiful — you’d never know there was any water damage! They truly went above and beyond. Highly recommend Jose and his team!"

"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."

Biohazard Remediation FAQs, 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.

While fiberglass dust is not generally considered toxic, inhaling the fibers can cause irritation to the respiratory system, eyes, and skin. Short-term exposure may lead to temporary discomfort, including coughing, throat irritation, and shortness of breath. However, prolonged or chronic exposure can result in more severe respiratory problems. Unlike asbestos, fiberglass is not associated with life-threatening illnesses. To minimize health risks when working with fiberglass materials, it is essential to use proper safety measures, such as wearing protective equipment like masks and goggles.

Rust in your bathtub occurs when iron in the water or on metal components in your tub are exposed to oxygen, but while it’s unsightly, it won’t make bathing dangerous. However, if the rust appears under or around your tub spout or shower head, it could indicate that you have high levels of iron in your water. Drinking water with small amounts of iron in it usually doesn’t pose a health risk, but you might want to consider installing a water softener. The presence of iron could indicate that you have hard water, which can create some plumbing issues.

Yes, carpet mold can spread if not addressed properly or quickly. Mold can spread to underneath the carpet, impacting the subfloor or attached walls. Mold and mildew can spread within the first 72 hours, so it is important to address the problem quickly and remove any affected carpet. 

The Environmental Protection Agency (EPA) only recommends removing mold yourself if the area covers less than 10 square feet. Beyond that, you should hire a local mold remediation company for testing and removal. These companies are trained for the specific task of handling mold and removing it safely and responsibly. The mold removal experts will also be familiar with the different types of mold and the best ways to handle each one.
