"Eran and his team were great. I had agreed to remodel my bathroom before moving in to my new house. It turned into quite an adventure once structural problems were identified during demo. Eran worked with me on trying to keep the bathroom timeline on track as I worked to get other contractors in to fix the other problems.  And they worked above and beyond in motivating me when the other contractors were late. We did run in to a slowdown at the end of the project and better communication would have been recognized - the problem was with a supplier outside of Eranâ s control. The end result was a slip at the end date for the project. Once everything worked out, I was very happy with the end result."

"James was referred by his friend to add an ADU. It's taken several months and this is how it looks. He refused to complete and fix what was already done. I am dissatisfied with James's work. He sent a family member, Roni run the job. Sadly, everything Roni touched was not done correctly. They did ask for money up front. Unfortunately I gave it to them. They didn't complete the job and refused to reimburse me for the errors made. He came to the site and few times and made all kinds of empty promises. He collected $53,000 up front. Now I have someone else who is fixing all of Roni's mistakes, which I will have to pay for again. He took advantage of me. That tells me he is dishonest. This is taking months to complete. I moved here from Florida and have seen whole houses go up in less time. James is dishonest, took money up front, didn't do the work correctly, and refused to reimburse me for what he didn't complete. Now I'm paying someone else to complete the job. Don't use this company"

"I called David to have a inspection of my garage since I was in the process of refinancing and the inspector wanted a letter from a professional mold company stating that there was no longer mold in my garage, since she saw some. I called 4 different companies, Dave was the only one who understood my need and did not try to sell me anything. He came the same day and after few hours he sent me the letter that I needed. Very reasonable priced, great customer service, fast and reliable. If I would ever need any other work for mold problem this is the Company I would call. Efficiency is very important for me."

"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."

FAQs for mold & toxic material test projects in Winnetka, CA

Some companies offer a no‑cost phone or video consultation that screens for red flags. If the discussion points to a real issue, the pro will recommend a paid on‑site inspection. The complimentary call clarifies whether you need full testing, but it isn’t a substitute for samples, lab work, or a written report. Always confirm what the free service covers before you schedule.

A standard inspection, which includes basic air and surface samples, takes an average of two hours. If the pro needs to probe hidden spaces, such as wall cavities or ductwork, plan on up to six hours. Extra time allows the inspector to reach tight areas, collect additional samples, and document findings. Lab analysis is a separate process and often adds several business days to the overall timeframe before you receive the full report.

Mold thrives where moisture lingers and air flow is poor. Common hotspots include bathroom walls, kitchen backsplashes, window sills, HVAC vents, fireplaces, crawl spaces, and enclosed attics. Check these areas regularly—especially after leaks or high‑humidity weather—to catch growth early and avoid costly repairs.

Unchecked mold can knock 20% to 37% off a home’s market value because buyers worry about hidden damage and health risks. Even after remediation, visible staining or a history of major moisture issues can still lower offers and prolong the time on the market. Addressing mold quickly protects both your property’s structural integrity and its resale appeal.
