Learn What Sets Us Apart

Our Services

We provide comprehensive environmental testing and assessment services to keep homes, businesses, and properties safe and compliant. Licensed experts handle everything from mold and asbestos to specialized chemical and allergen testing, delivering accurate results you can rely on.

Asbestos Testing

Our DOSH-certified technicians are state-licensed to perform asbestos survey and generate a formal written report that will indicate what materials contain asbestos at varying levels or the absence of asbestos.

Mold Testing

We offer the most technologically advanced and comprehensive mold testing available. Our technicians can identify the source of mold and prepare a full scope for remediation.

Lead Testing

Our technicians utilize XRF technology to detect not only lead-based paint on the surface but all layers of paint that may be present under the other layers of paint and deliver instantaneous results.

Bacteria/Sewage Backup

We can test sewage water, flood water or other degraded water contamination to ensure cleanup, disinfection and testing are successful so the living environment is free of contamination from microbes.

Fire & Smoke Damage Assessments

We offer professional fire and smoke-damage assessments, performing soot, VOC, and particulate testing with detailed analysis and pre- and post-remediation evaluations to identify hazards and ensure a safe, healthy property environment.

VOC & Formaldehyde Air Sampling

We offer VOC air sampling to analyze for any chemical compounds that may be present in your air and be cause for health complaints.

Methamphetamine & Fentanyl Testing

We provide on-site Methamphetamine & Fentanyl testing using surface-by-surface wipe sampling and advanced analysis to deliver fast, accurate results that identify harmful residues and guide proper cleanup to ensure a safe living environment.

Allergen Screening & Nuisance Dust Testing

We use the Total Particle Analysis to detect the presence of particles collected from the air or surface. Once analyzed, we determine possible causes of the excess dust accumulation so that corrective actions may be taken.

I need to review this company. This company is the kind of company you definitely want to do business with. I have had to use them personally and professionally. The multiple times we have needed a company for testing, they have not only met, but exceeded all my expectations. From the time you make your first call all the way through the end of your process, they have excelled like no other. In this day and age when you're looking for real customer service, these guys have it dialed in. If you need any testing at all, I highly recommend that you make the call to Rarefied Air. You won't be disappointed by any means.. Thank you so much "RAE". Job(s) well done!!!

We’ve had a great experience working with Rarefied for our testing needs. Their process is thorough, efficient, and dependable, which makes a big difference for us in the restoration industry where time and accuracy matter.

A special mention goes to Bruce, who has been fantastic to work with. He’s knowledgeable, responsive, and always willing to go the extra mile to make sure everything is done right.

We really value the partnership with Rarefied and the outstanding support Bruce any his team provides.

Dear Rarefied Air Environmental Team,

I am writing to express my sincere appreciation for the exceptional service your company provided. Your team is Quick, Accurate, Friendly and Clean!

In the past, we have worked with other testing companies for projects requiring testing and clearances. However, none have matched the superior level of service we received from Rarefied Air.

I highly recommend Rarefied Air Environmental, Inc. for your testing needs!

Sincerely,
Marko

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.

I've been using ( RAREFIED AIR ) for the past 10 years. I like their communication style. I get regular updates through email. When they have a question once they're on site they always call me for direction. What I'm saying is the job gets done right the first time. As a restoration contractor i find that insurance companies like to use their own people which can sometimes slow down the progcess. If you want things done fast within 24 hours call (Rarefied Air Environmental) Now I saved the B E S T for last. If you were to call around on pricing you would quickly discover that Rarefied has some of the best prices for environmental testing in San Diego. Cheers
