"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."

"I priced a number of companies for asbestos testing of a structure. Kurtis responded promptly and was able to conduct the test within just a couple of days of my call. They followed up with a call to let me know my results as soon as they were ready, the promptly mailed and emailed the final report. Very nice and total pros and the price is among the best in the biz."

"One of the paint estimators that I used mentioned that he thought I had mold on the ceiling. I wanted to make sure that there was no mold before I began the painting work. So I called The Mold Detective. I have never had an experience with calling a mold company before because I didn?t suspect we had it. They were very good, and I had good results with them. They gave me a certificate to show for sure that I had no mold. He was very thorough in all the work that he did and answered all my questions. He gave me a thorough report that I am comfortable to show if anyone asks for it. The price was a little stiff. They actually didn?t do any work other than check, and that did not take long. What I paid for maybe was for the report. I really thought that the price was pretty high. I would use them again in the future if necessary."

"Mold was found behind the walls in our master bathroom during demolition for a remodel. We contacted 3 companies for mold remediation estimates. Circle Vision wasn't the cheapest, but their review of the site and estimate was the most thorough, and they made us confident that they would do their best to reduce the amount of additional repairs that would be required after remediation was over. Carlos was the lead for our project and he did a great job explaining every step of the work and was very easy to get ahold of for scheduling. Gus Jr. and Gus Sr. conducted the remediation at our house for 2 days. They arrived on time each day, protected the floor with paper, vaccumed and swept at the end of each day, and left the house cleaner than when they left. They were very professional and answered any questions we had. They left an air scrubber at the house for a few days to make sure all traces of mold were gone. They left the dining room wall covered with plastic so our toddler and cats wouldn't get in to the unfinished bathroom. When the inspector returned, he found everything was done to the letter and we passed inspection with no problems.

FAQs for toxic lead testing projects in Diamond Bar, CA

If your home was built before 1978, there’s a strong chance it contains lead-based paint. Many pre-1980 houses also contain lead in their plumbing and decorative materials, so age alone is a significant red flag. Older homes near industrial areas face an even higher risk. Because you can’t confirm lead by sight, scheduling a test is the safest way to protect your family.

In older houses, lead can lurk in painted trim, window sashes, soil around the foundation, plumbing pipes, and even vintage hardware. The metal is toxic, and children and pregnant women are most at risk. Exposure can trigger developmental delays, learning problems, and organ damage. Because the EPA links even low levels to serious health effects, test every suspected surface and address any hazards right away.

A positive test means lead is present somewhere you can touch, breathe, or disturb. The next step is a full risk assessment to map exactly where the hazard lies and outline the safest fix: encapsulation, enclosure, or full removal. Repairs start at $1,000 but can exceed $10,000 for complete elimination, so act quickly and hire certified pros to keep your family safe.

EPA lead certification proves that inspectors, risk assessors, and abatement contractors follow federal safety rules under the Renovation, Repair, and Painting (RRP) Program. The credential costs an average of $300, and certified professionals can legally test, contain, or remove lead hazards. Hiring a certified pro protects you from fines and ensures the work meets strict health standards.

Lead-based paint looks no different from any other paint, so you can’t identify it by color or sheen. Even flawless walls may hide it. If paint starts chipping, flaking, or peeling, schedule a professional test right away. Only laboratory-grade testing confirms lead and guides the safest fix for your home.
