Mold Inspection Sciences Client Review
Five stars for Xander and Mold Inspection Sciences. Very efficient, professional, and informative
Brett C. Venice, CA, 4/28/2026

Erwin was great. He really walked us through the process and identified potential areas for concern and where we shouldn't be as concerned. We tried 3 other service providers, and they tried to sell you everything. We could tell they were not sincere in their evaluation. Erwin was the exact opposite. Very experienced, thoughtful, and helpful. He helped us choose where we needed additional testing. I would absolutely use Mold Inspection Sciences again since they keep people like Erwin on st...

I had an outstanding experience with Mold Inspection Sciences from start to finish. I was referred by a friend who had previously used their services, and they absolutely lived up to the recommendation.

From the very first phone call, their customer service was impeccable-- friendly, responsive, and informative. The inspection itself was incredibly thorough. Xander, the expert who came out, was professional, detail-oriented, and communicated everything clearly throughout the process....

Tim was great to work with. He was very personable, knowledgeable and provided us good information while doing his test. He was fair in his visual assessment of tests that we should do and those we should consider in giving us pros and cons for our decisions. I would highly recommend him and Mold Inspection Sciences for mold assessments.

Xander was one of the most professional workers that I've ever had. So unlike most kids his age.he was delightful fun respectful smart clean explained everything couldn't have been better in any way ....and I can be kind of annoying so he informed me about a lot and was very understandable and that was very nice compared to many people. Who are confusing and hard to read.

Vishal Redondo, CA, 3/11/2026

The team at Mold Inspection Sciences was extremely helpful. I emailed and called them desperate for an inspection and explained my situation. They were empathetic, and even though they were fully booked (weeks in advance), they still tried to fit me in. Both Sarita and, Kristian, went above and beyond to try to help me resolve my situation quickly. I was eventually able to get a same day mold inspection company so didn't end up using Mold Inspection sciences, but their empathy to my situat...

Irwin was so kind, knowledgable, and professional. He did a great job and was so efficient with timing. He was also super kind to my pup, who couldn't get enough pets from him! I would definitely request Irwin again.

If you need a mold inspector, look no further than Xander. He did a fantastic job. He was prompt, wildly knowledgeable, and incredibly thorough with his inspection. He took the time to explain everything clearly and made the whole process completely stress-free.
