    I have a long history with this company, and I feel I can rely on them for thorough and honest…read moretesting and reporting. As far back as 1995, we hired former owner and founder Peter Sierck to do a thorough assessment of our home in West Torrace. We had large patches of black mold in closets, behind furniture, condensation on the inside of windows into the late afternoon and damp carpets. Our home was built on a slab and when El Nino 94-95 slammed us with water. We had standing water wicking into the wall cavities, ET&T helped us find out. They drilled a hole in the slab to see if there was water pressure, took air samples and mold cultures from all affected areas, and provided detailed reports and candid advice. One thing I really like about this company is they do not do any remediation. That allows them to deliver an honest report whether test results are good, bad or indifferent. In 2022, I was smelling some strange odors in my current house and called ET&T to to a thorough test. Even though I now live in Menifee, over an hour from Encinitas where ET&T is based, they were able to serve my needs. This time around, Andrew, the current owner who was trained by Peter, and hs associate Brad came out to do the inspection. The test was free of any mold issues, thankfully. Once again, they were very thorough and provided detailed reports. Last update, I noticed last week (March 2023) that my engineered hardwood floors were black and starting to warp in a small area in one of the bedrooms. Even though I didn't have a current job with them, Andrew took my call late on a Friday afternnon, and made time to look at the photos I shared, and also donated his time to recommend what I needed to do, and didn't ask for a fee. If you have any mold you want tested, these guys are the best. Don't put your health at risk with an untrained plumber or worse yet, handyman, both of whom will have a vested interest in signing you up for remediation when there might not be a need.

    If you need mold testing in San Diego I highly recommend this company. They are mold experts and…read morehandle everything in a very professional manner. My husband and I recently found what we thought would be our dream home. We were about to finalize the sale until the inspector found some strange looking growth in the crawl space above the garage. He wasn't a mold expert but he said he was 90% sure it was mold. We spoke with the owner of the home and they were willing to pay for the mold testing if we were able to find a good company. I asked around and a few people recommended ET&T. I gave them a call and explained our situation. They reassured me that they would definitely be able to determine if it was mold growing and also told us that they knew a few reputable mold removal companies who could take care of fixing the mold damage if the tests came back positive. We were in a rush so they were able to send a testing specialist out that same day. 48 hours later the test results came back, positive. They gave us the number of a mold remediation company who was able to get rid of all the mold so that we could proceed with the home purchase. We just moved into the home and I feel so much better knowing that our dream home is mold free!
