Dealing with mold can be a very scary and nerve-wracking experience, but he was able to effectively dispel all the misleading myths and was able to frame the discussion in a manner that was both comprehensible and calming. Honest - based on his observation, he informed us which tests were necessary without trying to upsell; he made sure to inform us of all the cost/benefits of each test requested. Definitely would recommend LA Mold, especially when dealing with such a misunderstood, intimidating issue as mold.

Sean is the BEST!…read more Other companies have come and done the bare minimum, and so their air tests said there was no mold here (despite the strong stench in my bathroom that clearly indicates the present of mold). My health is suffering because of this mold, and even though I shared that with the previous mold inspectors, they didn't seem to care. Sean cared though. He is super knowledgeable and used his skills and gear and was able to prove that there is mold here. So now I can finally get it remediated. Thank you, Sean! So grateful for you!

So when a recent energy audit turned up some potential asbestos - I couldn't be more grateful for the referral that I received for A5 environmental. The response was unbelievably quick! During the phone call, Alan, talked me through the procedures, potentials, and really heard my concerns. A5 was our to our property quickly and the entire inspection was thorough and efficient. The report was back to me in record time. Having friends that have gone through this process with other companies and hearing about the headaches that can come from this situation - I was really anxious.

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.
