I had floor tile and mastic removed by an abatement company. I chose to hire Ryan and the Hazardous Materials Assessment to make sure there was no issues with air quality after the removal. Ryan was very thorough, answered all my questions, and provided additional information about the abatement process / contract that was very valuable. He handled the visual inspection, submitted the sample to a lab, and prepared the final report certifying the air quality results. Highly recommend Ryan and Hazardous Materials Assessment. read more

Great, local alternative to allow homeowners to test before doing DIY work. We have used them twice. First was years ago to before removing popcorn ceiling texture to make sure no asbestos. Recently to check for lead in paint before Home Depot would install new flooring. read more

Like someone else said, this was a pleasant experience. Not a headache. I literally dropped off the samples on the drop box and received my results in a few days. I had a few questions regarding asbestos exposure and they were extremely helpful. read more

I was very fortunate to work with Ryan Compton who helped me through a stressful incident. It is rare to find professionals that are so direct and honest about everything. I won't go in to all the details here but from the moment I spoke with Ryan I got the information I needed. He helped me with my asbestos issues at a rental house with tenants. He helped provide me with knowledge that calmed me down and also provided with the proper knowledge to help remedy a situation that was discovered. I am truly thankful for Ryan and his services. His honestly and candor were a breath of fresh air. read more

We had Ryan out to do some testing and what a professional! Our site has many challenges to access and rules that can be tough to follow. Ryan followed every rule to the letter, and was on time not only in his arrival, but in his estimate for completion. Add to that a fantastic customer service attitude and what else could you ask for from a family owned and operated local business? read more

Called this company and they were offering very helpful advice even before we had discussed if I would be doing business with them. They were super helpful and in the end I dropped off some samples for testing. The turn around time was quick and couldn't be happier. Will definitely go back to them if I have any more testing or mitigation needs on a future project. read more

Ryan was very responsive and knowledgeable. He took the time to talk to me, and he answered all of my questions. Thank you!

I can't thank Ryan enough for his helpfulness, integrity and honesty, I had an asbestos scare in my HVAC closet and after reaching out to many specialists, Ryan spent over 30 minutes on the phone with me helping me assess potential issues with the pictures I was sharing. It turns out a simple fix with metallic tape took care of the solution, but he was the ONLY provider I reached out to who was willing to assess the situation first over the phone so as to avoid an expensive in-home visit and assessment. Whereas many would have pushed for the ~$500 (and many providers indeed did) in person fee to assess and collect samples, Ryan was willing to spend time pro bono to give the most pertinent advice. THANK YOU and I will hire Ryan for any future projects read more

I called prior to their opening hours, expecting a voicemail, but was pleasantly greeted by Scott. I explained my situation and he basically told me that it didn't sound like I needed their services. I told him about a couple of reports that I had and he offered to look a them for me. Scott took the time to explain the documents and told me that I already had everything that I needed. Rather than simply taking my business because I called, he was straightforward and honest about the situation and he answered all of my questions. If you are still trying to figure out which company to go with, you can end your search. Go with HMA! Thank you Scott!!! read more

When I first called HMA for pricing on testing our popcorn ceiling for asbestos, I really appreciate that their immediate question was: Do you want to do this the cheap way or the expensive way? They then explained in great detail exactly how to do it the cheap way, while reassuring us that it was safe. We were therefore able to save money, which is great when you're about to spend thousands of dollars to remove all that popcorn! They were also very responsive to our inquiries; they were able to give us an estimated time frame when we called for an update, and then called to let us know the results as soon as they could. I hope I don't ever have to test for hazardous materials again, but at least I know who to contact if I do! read more

My fianceé and I were in need of asbestos testing for old ceiling tiles we wanted to remove in our newly purchased home. Unfortunately, we were in such a time crunch because we had to be out of our apartment the following week. I contacted Ryan the manager via Yelp, and received a response within minutes. He provided me with all the formation I needed to get the testing done ASAP. I was able to drop off samples the following day right when they opened and received the results the next day before closing. Results typically take 48 hours to process but luckily their testing moved quicker than we all expected. We are so pleased with the communication and professionalism we received from Hazardous Assessment. I reached out to multiple testing companies who did not get back to me timely. (It's 3 weeks later and some are STILL contacting me smh). My fiancé and I thought the tiles themselves needed testing but we came to find out that, Yes there was asbestos but it was in the underlying paint the tiles were attached too. Ohhh brother! Thankfully my fiancé took the extra step to chip off a piece of that junk. We were able to safely remove the tiles without disturbing the paint and now have smooth ceilings! We will definitely be back for more testing with Ryan and Hazardous Assessment. It's almost time to tackle to popcorn ceilings in the family room! Thanks again! read more

Ryan was awesome! I had a small sample of Sheetrock that I needed checked for asbestos before remolding . Ryan had me drop off the sample and sent me a report 2 days later. All for 35.00. Incredible service. Thanks again Ryan read more

I dropped off some samples to test for asbestos on a Thursday, and got the results in email the next Tuesday. The written report was received in the mail a couple of days later. I also spoke with Scott about the results and he answered my concerns. Very smooth and professional experience. Will definitely recommend them. read more

Ryan was helpful over the phone, explaining what needed to be done to have my house tested for possible asbestos. He was very courteous and patient with my questions. He showed up on time for the inspection and was extremely thorough. I would highly recommend him and his business. read more

Called and asked about testing for asbestos in popcorn ceiling. They walked us through getting small sample and I did a drop off at their Hayward office. Got a email with lab results within 2 days and a paper report in mail the day after. Highly efficient, good pricing, courteous and easy to do. Highly recommend! read more

HMA was recommended by our architect so we just went with them. I never thought an asbestos assessment could be such a pleasant experience. Ryan is the nicest guy ever. Look no further if you need this kind of service for residential, commercial or anything! read more

Ryan was helpful, informative, and friendly. If you're unsure about your hazardous material and want expert advise, this is your place. Thanks Ryan. read more

If you are looking for someone to test for environmental hazards in your home such as asbestos and lead, I truly can't recommend HMA enough. Ryan with HMA was incredibly patient and kind in explaining how dangerous (or not) various materials could be, doing a walk through of my entire home and identifying potential hazards as well as recommending what materials to test, and then spending a lot of time afterwards answering my multiple phone calls and emails with tons of questions. When we discovered some asbestos tape in our boot registers, Ryan also talked me through what I needed to do about it, and even got on the phone with an abatement contractor to tell them what needed to be done. I am a first time home owner of a very old home, so Ryan gave my husband and I a lot of peace of mind in knowing exactly how to remove or manage the hazardous materials in our home. While the lab tests are a little expensive, I think it was well worth it to know what I'm up against in our home. And also, Ryan is extremely kind and great to work with. read more

Very helpful, responsive, clear, informative, and professional! It was great to be able to have both mold and asbestos testing done. Ryan kindly and patiently answered our questions and provided guidance about next steps. Highly recommended. read more

Scott and Ryan were extremely helpful as they took me through the testing process. They taught me to take popcorn ceiling samples in a safe way and answered my many questions with great patience - really saved some headache. I appreciate their expertise and would highly recommend this business. read more

I needed some tiles from my kitchen tested for asbestos. I had some samples and did not feel like hassling with mailing them. I found these guys by dinking around on the web. I called and was able to deliver the samples directly. They were very patient with me (I got lost trying to find them - it's in an odd location) and very pleasant in squiring me to their office. Normally, they do building inspections for hazardous materials. (I noticed blueprints for larger buildings on a table. ) However, they also accept samples from members of the public for testing for a fee. Because they send in so many samples to the labs, they get a discount on testing, and will pass that savings along. I paid 70 bucks to have two samples analysed. (I just did this today, btw.) I thought it was really nice of them to do that for random folks. Bonus is that the guy who runs the place is a Terry Pratchett fan. I give these guys an approving "OOK" and five bananas up. read more

Ryan came to our house to inspect potentially asbestos containing material. He was not only very knowledge but also very patient and answered all our questions. Having done quite some research online, I was still able to learn a lot from his consultation and he was very responsible, giving us advice on how to proceed with our home improvement projects based on inspection and lab test results. If you have concerns about asbestos in your home and need professional advice, look no further. read more

HMA was extremely easy to work with. They communicated with us immediately to assess our bathroom tiles for asbestos. Thankfully we didn't have any and they provided the test results in a timely manner. I would recommend HMA to anyone that needs this service. read more

Outstanding service from this well-established, family owned company when I needed asbestos inspection required for demolition of our old garage. They got back to me quickly, were precise about the pricing: a base figure plus $35. per test, arrived promptly at the scheduled time, were efficient and personable, and sent the written report within a day or two. Highly recommend. read more

I recently put out bids to redo my attic insulation and one of the three contractors that put in a bid advised I needed to get my old insulation tested for vermiculite asbestos. I thought it was odd that only 1 of the 3 was concerned about it, especially since in my opinion the material in my attic looked nothing like the photos of vermiculite I saw online. I decided to consult with Ryan who was upfront, honest, and very communicative. Based on my description he was pretty sure it wasn't vermiculite, but had me send over some photos to double check. He confirmed that the photos I sent looked nothing like vermiculite and that testing was unnecessary. This saved me hundreds of dollars of unnecessary testing fees, and despite Ryan not making one penny of this consultation, his honesty and straightforwardness spoke for itself. Operating with integrity is the gold standard for any business, and should I ever need asbestos testing or inspection services in the future I won't hesitate to use this company. read more

I can't imagine that there are any hazardous materials experts out there who are more skilled, conscientious, thorough and trustworthy than Ryan and Scott Compton. I called HMA last year when I was hoping to find someone who could do a complete assessment of the status of the asbestos-wrapped heating ducts in my home's basement. I was pretty sure that all was going to be OK, but I wanted the final word and lab testing from the experts before I made some big home-improvement decisions. Not only did Ryan and Scott immediately put me at ease with their clear explanation of the air and dust sample testing process, but they also listened and answered patiently when I pelted them with question after question, never condescending or making me feel like I was overly concerned. When the lab samples came back showing that everything was fine and there had been no contamination at all in the house, they called me immediately with the good news. I really felt like I had received warm, generous and highly personalized service. I highly recommend HMA and know that you, too, will be impressed with their depth of knowledge in the field and their extraordinary service. read more

Glad I used these guys. Very professional and communication was on point. Very knowledgeable and got my samples back quickly so I could find out about my asbestos results. Thanks guys! read more

This is the guy you want in your corner when you are trying to manage the sometimes scary experience of asbestos remediation in your home! Having him as an unbiased player when I was in tense discussion/negotiations with an environmental remediation companies was immensely reassuring. He helped me make the best informed decision to keep my home and family safe. We hired Ryan to test our house and crawlspace for asbestos. We were in the midst of a very confusing and scary time trying to remediate old asbestos from the ducting in our crawlspace that had been partially destroyed and degraded over time. Ryan's technical knowledge and thourough approach to reviewing our house was top notch. He also did not require air sampling tests (some testing companies have minimum of 3 TEM tests per visit and ~200 a pop, that adds up). Ryan said that we really only needed one to rule out a problem and if we failed that test, we might need more. He also explained a lot of how the remediation industry works, contractors, regulators, testers the whole shabang, so that I could understand why contractors were acting in ways that did not make sense to me at all! Most importantly, he helped me understand where any health risks could exist for our family and helped us map out the potential actions we could pursue to address/eliminate the risks. read more

I was very impressed with the high quality of HMA's asbestos inspection and follow-up report. The report provided my family with important information that we needed. We really appreciated Scott Compton's expertise. I highly recommend HMA's asbestos inspection services. read more

Really good experience. Ryan was easy to work with, arrived on time, and explained everything to me. Best part - I found out I have no asbestos risk in my apartment (confirmed with visual inspection and an air sample)! read more

Ryan provided me with excellent professional help from the very beginning phone call. He explains the different types of test thoroughly and patiently before I paid him a dime. He even sent me a list of service providers before I hire him. After many comparisons I decided to hire Ryan for asbestos air testing after my popcorn ceiling was removed. He was punctual and trustworthy-- he rushed my test to the lab and the result came out earlier than he said, thus saving me hotel stays and subsequent remodeling tasks. I learned so much about asbestos from him. What touched the most was his sincere demeanor and superb customer service attitude. Ryan is a joy to work with. Highest quality of service I have ever found! BTW, his price is also the best in Bay Area!!! read more

As mentioned in the previous review these guys do sample testing at a very reasonable rate. I had some building materials tested and and also an evaluation of my home done and I am very pleased with the work. Very friendly and good down to earth guys who I recommend very highly! read more
