    Hello, my name is Haeil. Our tenants requested to test some old tiles for radon. They are located in Alhambra. Is it possible to get some information? Thank you

    Hi, thanks for the question! I don't do any testing for radon at this time. That may change in the future, so any potential clients that are seeing this - feel free to ask again when your next project comes up!

    Steve was patient, fair and very knowledgeable as I was trying to navigate testing for lead after the LA fires.

Alexis came to collect samples and called to confirm before arriving early. He did a very thorough test and was very respectful of my place. When I mentioned my home is shoe-free, he kindly put on shoe covers without hesitation. Fantastic team! Hopefully I won't need their services again, but if I do, I'll definitely return.

    This is the second time I've used JLM and I'd still recommend them. I'll list the pros and cons of…read moremy experience. Positives: Friendly customer service. Good communication and quick scheduling. I was able to have a technician come out the same day I called to schedule. The technician was extremely friendly and helpful. He answered all my questions while he was concentrating on the testing, set up etc. He was careful with his words meaning he didn't cause any unnecessary stress or anxiety. He wasn't pushy and was conscious of the cost while also recommending what samples are needed or suggested. He was clean and careful. Cons: Expensive compared to other mold testing companies. The invoice can quickly add up. I originally planned for about $800 ($500 base fee plus $75 for 4 samples). I added on asbestos test and that brought my bill to over $1300. In some ways I see this as a positive though because you get what you pay for (I hope and can't compare to any other company). My whole house wasn't moisture mapped as I was told it would be. The tech said they only focus on the reported areas of concern. Not a big deal but would've been nice to know. I kept getting rescheduled by 15 minutes. The tech was running late then running early so that was a little confusing. I jokingly asked them if I get compensation for the changed appt time since I signed the contract already (they charge $150 for any changes). They said no. The report is a bit confusing as it was the first time. The most annoying is that in the asbestos report they suggested further testing. Likely costing another $1000 or more. I thought I was already paying for the best testing. This feels a bit like a trick in some ways. Overall I'd go to JLM again. I suggest to do some research beforehand though to know exactly what you need done (AND WHY meaning are you renovating or just wanting to know for health reasons etc) so you don't get unneeded tests or costs.

    Outstanding responsiveness and professionalism. I reached out to Marshall GeoScience through Yelp…read more Marshall (the principal engineer) replied quickly--even continuing the conversation well after business hours and offering to jump on a call. I wasn't exactly sure what I needed at first, and he was incredibly patient while I tried to explain the situation. Rather than guessing, he took the time to understand my goals, clarified that a firm estimate would require a defined scope of work, and laid out what that scope should look like so I could move forward confidently. What stood out most was his clear communication, transparency, and willingness to help without any pressure. I'd contacted a few other firms before him and had mixed results. Marshall was by far the most responsive and helpful. If you need a geotechnical engineer who is prompt, thoughtful, and genuinely focused on setting you up for success, I highly recommend Marshall GeoScience.

I contacted a substantial number of other soil engineers who: -Didn't understand the request. -Said it was too small for them. -Were too busy. -Never responded. -Insisted on doing a massive (EXPENSIVE) report. One firm - Marshall - responded immediately, took the time to review the plans in detail, called the city, and got specific needs. He immediately came out, did the site inspection and within a week had a full report. And at a very reasonable cost. I cannot recommend Marshall GeoScience more highly -- exceptionally professional and willing to go the extra mile!

I have met numerous industrial hygienists on sewage, pollutant, trauma/bodily fluid, smoke and fire damage claims. Too many hygienists talk a good game but fail to deliver when it counts. Sol Environmental is better. Sol was recommended to me by a senior entertainment attorney overseeing a large legal team, and that endorsement proved accurate. When I first met with Raul and Nick at Sol Environmental, I immediately recognized their technical depth and concern for the clients. They discussed testing protocols for contaminants that most hygienists overlook or simply don't understand--particularly the volatile organic compounds and particulate matter that pose serious health risks in post-fire environments. When other hygients test for lead and asbestos, Sol is testing for everything: mercuty, silica, arsenic, dioxins, cadmium, barium lithium, you name it in addition to the lead and asbestos. What sets Sol apart is their background as specialty remediation contractors. They don't just identify contamination--they understand the actual remediation process, which makes their protocols far more comprehensive and defensible than what I typically see from competitors. Their protocols meet the standard of care, which is rare in this field. Sometimes I just need good sampling and lab results. But if i need a defensible step by step protocol, Sol is great. More importantly, they're willing to stand their ground when insurance carriers bring in questionable experts pushing junk science to minimize scope and deny proper remediation. Sol backs up their findings with solid scientific evidence and proper testing methodology. In claims where bad faith is already an issue, having a hygienist who won't fold under pressure is invaluable. I've referred Sol Environmental to multiple clients, and they've consistently helped secure the proper remediation my clients deserve. They do difficult work in contentious situations, and they do it well. I recommend them without reservation. Leland Coontz, Public Adjuster license #2B53445 (714) 724 1767

I got the testing done, it came back positive for asbestos. I panicked. I called Pacific Environmental for an estimate on the job. Armando and Arturo came out to assess the job and provide with me with a quote. To my surprise, the price was only slightly higher than the regular remediation company. I was pleasantly surprised by the affordability. Additionally, they promised me the job would be completed in 1 day! WOW! This would be best case scenario. The office staff was also very kind and helpful with prompt estimate and response time. Today was the day of the job, I was very anxious and worried due to the fact that my parent's house is very old. The job supervisor, two workers and Arturo came out to ensure that everything would be okay! They did a superior job, kept everything clean, taped off all areas and did a great job with containment! I am so grateful to the PEAS team, now I can breathe easy and I am so relieved! I highly recommend this company for any abatement project. Great price, great customer service and great quality work! They listened to everything I asked for and delivered above and beyond! Thank you to the entire PEAS team!
