Great service and honesty. Came to inspect quickly but it did take an extra day to receive our results.

To say I had a great experience with Rarefied would be an understatement. My wife & I were remodeling a nursery room for our firstborn, when we noticed popcorn ceiling dust scrape off crown moulding. We're young and had no idea what we were doing in dealing with asbestos! I called Bruce early in the morning and explained what happened - he was thorough in his explanation, helpful, and expedient in getting me scheduled. No pressure, just incredibly helpful. Rory was also outstanding. He was concise in explaining asbestos, valid concerns, and the policy surrounding it. He came within an hour, took air & material samples, and I received the lab results same-day. It was exactly the service I asked for. We were safe! Given their prices are already some of the most affordable, and their results are so quick, I would recommend EVERYONE start w/ Rarefied. Their team is kind, responsive, and got me everything I needed for peace of mind for our new baby's nursery. Thank you Bruce, Rory, and Yumi. I appreciate you guys very, very much read more

I have worked with Bruce and Rarefied Air many, many times over the years. The reason why? They are THE best at what they do. Plain and simple. And, Bruce is the most knowledgeable person in his field you can find. Highly recommend using them. read more

This company is top notch! Lori and Hans know are kind, professional, experienced and knowledgeable. They made the whole process seem a little less overwhelming and spent more time than they needed to with me and explained what needed to be done and how a potential asbestos problem could affect my family and how to handle my household if a positive test occurred. I cannot recommend them enough! They took a very stressful situation and provided me with some peace of mind. read more

I would strongly recommend avoiding this company. My insurance adjuster told me I did not need asbestos testing, but my contractor refused to begin work without it and connected me with Rarefied Air. That should have been the first red flag. When I spoke to Rarefied Air, I asked them if we needed to get preapproval from my insurance company, and they told me there was no need and they would take care of it. Now the job is done, insurance won't pay and I'm left with the bill. For me, it's the principle of the thing: If they tell me I don't need preapproval, they should be prepared to stand behind that. I took their word for it and it cost me. I'm giving two stars rather than one only because they did give me a 20% discount. I shouldn't have had to pay at all - and based on what my insurance company told me, I likely had my arm twisted into unnecessary testing. read more

I have been using Rarefied for several years on jobs that my company works on that need asbestos and/or lead testing. They are flexible and easy to work with and will accommodate my customers' scheduling requests even when it is last minute stuff. Matt and Bruce, the owners, are good people and are excellent at what they do. Thank you for all your assistance. read more

Quick and professional. Found out that Home Depot requires a certificate of Clean for asbestos on linoleum floor replacement for houses built before 1992. Surprise! Called up Bruce at Rarefield and they were able to come, sample, take to their lab and provide results/certificate the next day. Quick, excellent and efficient. Rarefield is the gold standard place to go in San Diego for environmental testing. read more

I just want to say that, after 30 years in the restoration world. I have yet to meet or work with a company such as that I am proud to send out to meet my customers, Profession, Polite, Commutative and always on time, Everyone Loves, Bruce, Matt Hans, and Yumi. I know we do! read more

Fast and reliable service, very easy to work with them. They are professionals I highly recommend them. read more

Bruce was a word of mouth referral. His prices are reasonable, his professionalism is on point and his team is attentive and courteous. I can sum up my experience with Rarefied Air Environmental with three words: peace of mind. He walked me through the process of collecting asbestos samples from my home, he gave me a quote over the phone and delivered on his word. His office team (Maria) and field rep (Gabe) have great customer service and do things right the first time. As a business owner myself, Bruce and his team treat clients just like I treat mine. I'll be sure to refer this business to friends and family. read more

I can't begin to thank Rarefied Air for the help they provided in a recent mold issue we had. They came highly recommended from our restoration company and I'm so happy that we were introduced to them. Matt and Rory were so knowledgeable in answering all the questions I had throughout the process. We had a tricky situation with a subterrain home and Matt was able to guide the restoration company to uncover the last part of the mold issue. They were responsive scheduling was a breeze. I appreciate all their help!! read more

Had to get an asbestos test for a remodel last minute and Rarefied was able to send a sampler out within two days. Hans was super nice, professional and on time. Really appreciate how speedy and easy everything was, will definitely recommend! read more

Bruce and his team are 100% industry leading. From my first conversation with Bruce about possible asbestos in my condo he was a professional and clearly explained what to look out for. I would absolutely trust Bruce and Rarefield to handle my next property. 100/100 read more

Very professional, friendly and accommodating mold testing service! I run a property management company and Rarefied was able to schedule mold inspections right away with results the same day or a day later for a reasonable fee. They also provided very detailed reports including advice on how to treat the mold that was discovered. All the questions from myself and the tenants were answered right away by the friendly inspectors who visited the unit. Matthew, the owner of the company and lead inspector would always answer the phone or return a voicemail promptly if I had any additional questions about the mold reports. I fully recommend Rarefied for any mold testing or mold analysis of your home or rental property! read more

Very quick and painless experience, fair price, explained the process well. Digital-friendly with contracts, reminders, emailing results. I'd definitely recommend this company to a friend and use them again myself if needed. read more

I worked with Rarefied in July and they were very professional and friendly. They answered my phone calls promptly and were patient in answering my questions. They ensured that I had the proper information I needed for asbestos testing. I would highly recommend their services. Other companies were not as responsive and tried to rush me into booking with them. Dealing with home hazards can be incredibly stressful and I feel glad that went with Rarefied. Don't hesitate to give them a call! read more

As a service business owner I believe I have a keen sense of whether a company understands my needs as a customer and is looking our for my best interests (not to just line their pockets). We all expect to pay for the best service we can get for the money and with Rarefied I can tell you that's just what you will get. Bruce will explain the problem, the solution and help point you in the direction of the right, qualified abatement or remediation company to complete your job in a manner that will leave you with the peace of mind your looking for. No one necessarily wants to be in a position to have to need this service, but when you do, believe me you are getting a great team to help get to the right solution. read more

Very reliable company; we used them to test for asbestos throughout our new residence and they came out in a timely manner, provided complete report, for reasonable price. Then, we asked them to come test for clearance, after abatement, which they again did in a very timely manner and reasonable cost. I would recommend them for anyone who is looking for environmental testing services. read more

We were prospective house buyers with a tight deadline and wasn't sure if some popcorn ceiling material might have asbestos. The President of Rarefield Air immediately responded to my request for a quote on a weekend day & scheduled his team to take samples by that Monday morning. Their prices are reasonable as I had gotten 2-3 other quotes. Their team was professional and I was so glad that I scheduled an asbestos inspection because two areas came back positive. This information was critical in our decision to buy this home and the possible health implications. Thank you again to Bruce and team, I'll certainly be a repeat customer! read more

Easy 5 stars. I called needing quick input and Bruce was excellent. 87,000 surveys worth of experience makes him a true expert in my book and a go to partner for air quality challenges in your home. I agree with the prior "peace of mind" comments in the reviews - don't hesitate to make this call - it's a sure thing. read more

I had the pleasure of working with Bruce & team when I needed asbestos and lead testing for a job at my house. A technician came out right away, performed the work very quickly and respectfully, and then I got the results overnight. It was important to get someone onsite fast since contractors were waiting to open up certain areas, but wanted to have the go ahead that there were no risks. Bruce was an excellent communicator, and he helped me along the way with the process. He was also aware of the financials of the situation given limited insurance, and worked with me to get the work done within a very reasonable budget. I'd use Rarefied Air again because of the professionalism and customer care offered to me, and I know others would have a good experience working with Bruce & team! read more

We got quotes from a couple of companies for asbestos testing at our house as it seems some parts containing asbestos was disturbed in our home in the renovation before home sale and chose Rarefied Air and it was a good decision. Aaron who came to our house for testing is very knowledgeable and helpful. Though testing was done in the landing area, he went to the attic to check about the disturbed part and took some clarifying pictures to show us what was going on. I would go back to them in future if I need some testing. read more

Thank you Bruce for the years of support and great service. Our staff and our clients appreciate all you've done for us. Keep up the good work. read more

I called Rarefied Air Environmental to perform some mold testing for me at one of my San Diego properties. I spoke with Yumi at the office and scheduled an appointment for the same day. Bruce was able to get someone out the same day and get me results by the following day. Yumi and Bruce were very patient, polite, and informative. I recommend Rarefied Air to anyone that needs any type of environmental testing (mold, lead, asbestos, bacteria, etc.). I will definitely be calling them again if I ever need testing at my properties. read more

I was told that I might have asbestos under my tile. The flooring guys packed up and said you need to get it tested before we can come back. I was very stressed and a friend gave me the number to Rarefied Air Environmental. I called and spoke to Araceli and I explained my situation. She was more than fantastic! She got someone out that day and I received my results the next day. She even called to check how things were going. I have not come across such fantastic customer service in such a long time. A bonus is the price I paid was less than the estimate. I will refer everyone that needs this service to this company! read more

Great job overall...came fast, tech here x 1 hour, great report at end, fair priced @ $395. for small Kitchen area mold analysis. Would recommend. read more

Bruce from Rarified Air Environmental is knowledgeable and patient in sharing information about asbestos testing. He has very competitive and fair prices. He spent time with me and explained the process of asbestos testing for my individual home owners situation. He was encouraging in finding other resources beyond his business' realm that I needed. I felt much more confident after talking with him, about the situation. read more

Bruce and his team are an absolutely phenomenal company to work with. They are responsive, thorough, and very professional. Everyone I have interacted with at the company has been wonderful. read more

I would give this company 10 stars if I could. Of all the professionals we dealt with during an asbestos problem in our home, the team at Rarefied air were hands down the very best. Hans provided detailed education to me when he came out to that helped to set my mind at ease. Tom came for the air clearance test and was on time, professional, and also helped me understand the process. And the cherry on top is Bruce, the owner, who took the time to discuss the issue with me at length and help to ease my (significant!) anxiety. This team is the absolute best! read more

During Covid and the Holidays, I really wanted to do my part and support a local business especially one in my neighborhood. Found this place while searching throughout san diego.

If you are are looking for honest people to work with, these are your guys. read more

Bruce and the guys at Rarefied are the absolute best in San Diego at what they do. Their turnaround time for testing and results is unmatched. They have amazing customer service and can make tenants, business owners, homeowners, anyone, super comfortable with the process and with the purpose of what they are doing. Mold and asbestos can be scary and obviously a lot of cost can get attached to them. Rarefied is extremely low-cost compared to their competition because they do things right the first time. They provide clear written explanations of their results and do not leave you hanging. read more

Rarefied Air was contracted by the HOA to do inspection and testing for mold after it was discovered during our home inspection. They were scheduled and arrived the next day. Hans did the testing, and he was very helpful in talking to me for 30min afterwards to go over everything! Wouldn't hesitate to use them. read more

Excellent company! They're quick, affordable, and very professional. We give mad props to Bruce for keeping it real when it comes to questions of concern. He took the time to explain the process, the results, etc. His customer/people skills are top notch and such a relief in this days market. Rarefied Air Environmental is the right choice, has the right people and leaves you with a good feeling that exemplifies exceptional customer service and high quality work. read more

We accidentally disturbed some of our popcorn ceiling, which we knew contained asbestos, and wasn't sure how to safely clean up the small amount of debris that was scattered on the floor or if we should get the air tested. I called Bruce, who gave me a safe and easy solution that would not end up costing hundreds or thousands of dollars (which would have been the cost if we had brought in an asbestos abatement company). He made no money at all on this so I'm posting this review in thanks. I would definitely recommend contacting him if you need the services that he provides. read more

I can't thank Bruce enough for his expertise and assistance. He took the time to discuss my laundry room issue and walk me through the best way to move forward to keep my family safe. If you are looking for an honest company and person please contact Bruce at Rarefied Air Environmental. read more
