Highlights
- Dog-based detection — reviewers describe Theodora accurately pinpointing hidden mold
- Fast scheduling — one customer had an inspection booked for the next morning
- Clear walkthroughs — reviewers cite thorough explanation of the process
Massachusetts Mold Dog is a South Shore business built around one specialized job: sending a trained detection dog, Theodora, through a house to sniff out hidden mold before anyone starts guessing where to open a wall. It's run by Brianna, a longtime police K9 trainer who says she got into this after dealing with an undiagnosed mold problem in her own home; she holds NORMI certifications as an IAQ/Mold Assessor and a Mold Remediator. The company says it covers Boston, Quincy, Braintree, Weymouth, and the rest of the South Shore. Every review posted so far — five of them, all five stars, all from this spring — describes the same visit: Brianna walks the property and explains the process, then brings Theodora in to alert on specific spots. One homeowner said the dog alerted on a ceiling that turned out to be hiding mold from an old roof leak, and near a washer, both confirmed on the spot. Another said they called and had someone at the house the next morning. The praise is consistent and specific, but it's still a short list — all five reviews landed within a few months of each other on Google, with no longer track record yet and no listing found on BBB, Houzz, Thumbtack, or Angi to cross-check against. This is a detection-and-verification service, not a remediation crew: expect an inspection, a canine alert if something turns up, moisture or thermal confirmation, and guidance on next steps rather than someone tearing out drywall that day. That fits anyone who suspects hidden mold behind a wall or ceiling and wants to know exactly where to point a contractor before opening anything up. Given how new the review history still is, it's reasonable to ask how her Mold Remediator certification factors in versus bringing in a separate remediation company for any actual removal work.

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.

From the moment they arrived, Brianna was incredibly professional, knowledgeable, thorough, and compassionate. She took the time to explain the entire inspection process, answered every question with patience and expertise, and made what could have been a stressful situation feel much more reassuring and manageable. Watching Theodora work was absolutely amazing — her training, focus, and accuracy were beyond impressive. It was clear this team is highly skilled and dedicated to what they do. What stood out most was Brianna’s honesty, attention to detail, and genuine care for helping us ensure our home is safe and healthy. You can truly tell she is passionate about her work and committed to providing exceptional service. I would highly recommend Brianna and Theodora to anyone in need of mold detection services. Their professionalism, expertise, and compassion exceeded every expectation, and I am incredibly grateful for the peace of mind they provided.

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!
