Massachusetts Mold Dog is built around one distinctive tool: Theodora, a trained detection dog who can find hidden mold that moisture meters and thermal imaging alone would miss. Founder Brianna, a longtime police K9 trainer, started the company after dealing with health issues from mold hidden in her own home, and the operation is NORMI certified as both a mold remediator and an IAQ/mold assessor, serving Boston, the South Shore, Quincy, Braintree and Weymouth. The five reviews on file, all from 2026, describe a consistent process: Brianna walks through the inspection first, explaining what she's checking and why, then brings in Theodora to search spaces — tight crawl spaces, ceilings — that would be hard to inspect visually. In one review, Theodora alerted to a ceiling spot that turned out to be mold from an old roof leak; another reviewer said the response was nearly immediate, with Brianna and Theodora on-site the next morning and finding mold near a washer that was cleaned up right after the inspection. Reviewers consistently mention Brianna's own experience with mold health issues coming through in how she talks with families, and her patience answering questions is a recurring thread. With five reviews all landing in a single spring, it's a young track record — worth confirming what happens after Theodora flags a spot, since the reviews describe detection and some spot-cleaning but not full remediation scope.

I cannot say enough good things about Brianna and Theodora. From the first conversation, Brianna was professional, knowledgeable, and genuinely passionate about helping families identify potential mold issues in their homes. She took the time to explain the entire process clearly, answered every question, and made what could have been a stressful situation feel much more manageable. Then watching Theodora work was incredible. Her focus, training, and ability to search areas that would be hard to inspect visually was extremely impressive. What stood out most was how thorough they were. Theodora was able to detect potential problem areas quickly and accurately, giving us a much clearer picture of where hidden mold concerns may exist. Brianna’s experience, honesty, and attention to detail gave us real peace of mind. If you are dealing with possible mold, water damage, musty smells, or just want confidence that your home is safe, I highly recommend Brianna and Theodora. They are professional, reliable, and clearly care about helping people. Truly an excellent service.

Brianna and her K9 partner were great. Brianna came in without her dog first, explained the process and was very thorough with every explanation. She then brought her dog in and watching them work was great. Her K9 alerted to a spot in my ceiling that ended up being mold from an older roof leak. Her dog alerted on the ceiling from the floor, which was extremely impressive. Also, some mold was detected around the washer and was quickly cleaned after the inspection. Very happy with the service and quality of the dogs skills.
I cannot say enough good things about Massachusetts Mold Dog. I reached out to them and the response was nearly immediate. Brianna and her dog, Theodora were at my house the next morning! They showed up on time, professional, and well prepared. Theodora was able to crawl into tight and narrow spaces and did not miss a beat. She hit on numerous spots in my home and was eager to keep her search going. Brianna shared her personal experiences dealing with mold with me and my family. It is clear that the mission that drives Massachusetts Mold Dog is genuine and comes from a place of experience and trust. I highly recommend Massachusetts Mold Dog to anyone looking for accuracy and a company that can be trusted!
