I had this weird musty smell in my house mostly when I had the AC on. I had someone come look at the AC unit and they said it was fine. The smell wasn't going away so I thought maybe it was mold. I called Frank and Sonia and they were able to schedule an inspection for the same. Frank came and sent a little robot camera under the house and was able to find the smell that has been driving me crazy for almost two months now. The main sewer line is leaking and there's sewage just sitting beneath my house. Frank was great he even recommended a company to come and clean the soil from bacteria. So glad this mystery smell was finally solved. read more

Original review (2/9/23, one star): "Since we do not perform mold abatement and removal...there is no conflict of interest for our valued clients." Which is precisely why I eagerly called Hidatsa for mold testing, and even mentioned this Yelp quote yesterday when I made the appointment with Sonia. But when Frank came out this morning to check two separate areas, he told me he could take a large sample of the area I was most concerned with, but their tests on that specific area would most likely return "inconclusive." So.....he suggested calling a mold abatement/remediation company to have THEM test that area. Seriously?! Don't worry, Hidatsa: you'll still get paid your $445 ($395 = service call, $95 = sample from the other area), but you certainly won't get any referrals from me. Not the best use of my time and money. Update (3/24/23, three stars): Almost thirty days after payment, and still no word from Sonia or Frank. I contacted Sonia on 3/16/23 and asked where the test results were. She said she'd contact Frank immediately (mentioning to me about some sort of "personal emergency" Frank was having) and ask him about them. She called back a short time later and said they'd refund my entire payment and forego the test results. In exchange, she asked if I'd "reconsider" my Yelp review. I told her I would after I received my refund. (Still unsure about their explanation for "inconclusive." Sonia said on 3/16 they didn't want me to "waste my money" testing an area that most likely would come back positive -- frankly, I'd rather spend the money and have the result in writing. Also hoping Frank's month-long "personal emergency" has been resolved.) Refund finally received yesterday (3/23/23), review amended to reflect. Yelp officially discourages removing reviews after receiving refunds, but review updates aren't possible after 30 days. So you're welcome, Hidatsa, for removing the original one star review. read more

My mom once told me if there isn't anything good to say rather say nothing. She was wrong about a lot of other things as well, so here goes: I had a leak and the tenant said there is mold. My tenant was manufacturing reasons to get out of the lease early (pertinent later). I did see some mold though, and I'm planning to sell, so I want to do the right thing. I called Hidatsa to get a quote for a mold test to start the process. Sonia tells me that it'll be a $400 inspection fee, and $95 for an air sample. I say fine and make an appointment with my tenant. She sends me a meeting invite with the wrong address. I email her back, saying they have the wrong address. The day comes, and I get a call from Frank saying he can't find the house. Sigh. He eventually gets there, and phones me back almost immediately, and says yes there is mold. Ok, I knew that much already. Now that he's earned the $400 inspection fee, he asks me what type of sample I want. I say I ordered an air sample. He then tells me that I will also need another air sample to compare the laundry room sample to (taken outside), otherwise the air sample in the laundry room is useless. That'll be another $95, but if I don't like the air sample idea I can also get a surface sample for $95 (I do like the air sample idea, but I'm pissed that I wasn't informed that it will cost another $95 for it to be useful). If I want all of the samples, it'll be $685. Then, if I need remediation they will have to come back and test it again (at full price). After some discussion (which involved a teleconference with Sonia who just listened) I decide on the surface sample, as it will tell me what type of mold it is, and how much of it there is. Frank goes ahead and earns his living for another 5 mins before leaving. When Sonia phones me for payment I ask her how long before I get the report, she tells me 2-3 days. Based on this I phone my contractor to find out his availability. Because I use him a lot, he makes space for me in his schedule for 4 days hence (which is when I'll have the report for sure.) On day 2 I call Sonia and leave a message. She doesn't return my call. Repeat for day 3. On day 4 my contractor is there, but what isn't there is the report in my inbox. I finally get hold of Sonia mid-morning, and she unapologetically and indifferently informs me that Frank isn't ready with the report. I ask to speak to Frank. He says he'll have it for me by the next day. I protest a bit, saying Sonia told me 2-3 days. He says well he's the inspector and it'll be 5 days. Ok, but only because he's the inspector (!?) He finally relented and said he'll get the report to me by 4pm. I get it, and it says (amongst other very badly written things): "During the inspection process the tenant showed me the areas that were of concern which were in the kitchen , dining room, middle bedroom and in the master bedroom. Inspector indicates mold was found in each of the rooms except for the dining room. This is due to moisture intrusion through the doors and windows. Remediation will be necessary in order to abate the molds properly." Erm, WHAT? I phone my tenant and ask him (in a barely controlled rage sort of way) why he told the inspector that there was mold in these areas when they weren't even a concern, and where is this mold anyway because there are no signs of it. Needless to say, with tensions already running high, this conversation did not go well, but my tenant swears up and down that he didn't say anything to the inspector aside from showing him the mold in the laundry room. So I phone Hidatsa. Again. I speak to Frank, read the passages to him and he starts to.... laugh! Yes, laugh! Like this is the funniest thing ever! Oh no, he says, he forgot to change the boiler plate text, and that's not actually accurate. Apparently, normal people just jump to the photos, and why don't I just look at the photos instead? Plus, amazingly, I am the first person to spot these mistakes, and they've been in there for YEARS. While this impressed me about my own reading and comprehension abilities, it really did not impress me about his attention to detail. I told him as much, but he protested in his own defense that I asked him to complete the report in a timely fashion, which lead to the mistakes. So not only is it my fault for spotting the mistakes nobody has spotted in years, it is also my fault that he made those mistakes... years ago? Gaslight much, Frank? I finally receive the final report after 3 tries, each time finding more mistakes and talking to long-suffering Frank each time, whose attitude is that I'm being a totally unreasonable Karen. In summary: They're overpriced for what's being provided, slow, inept, disrespectful of their customer's time, plus they'll gaslight you into thinking you're at fault. So unless you have cash to burn, not in a hurry while trying to treat your mold situation, and prefer inaccurate reports, avoid. read more

Frank is great, super easy mold test and quick results. Would use again but hopefully I won't have to.

Frank is not only professional, thorough, and amazing at his work, he is also such a kind person who you want to work with. He clearly cares about his customers and doing right by them. I can't say enough good things about this company! Don't look any further, you must choose Frank and Hidatsa Testing . read more

Great guy. Came quick. Explained it all. Sent a follow ip email very quickly. Very responsible.

I was so impressed with Frank's knowledge and I felt assured by knowing that he only does the testing (not the mold remediation) so there's no conflict of interest. Frank actually pointed us in the right direction with figuring out the source of the odor in our bathroom even though it tested negative for mold. It turned out to be a cracked vent pipe inside the wall. He went above and beyond and was a huge help. read more

I have been using Hidatsa Testing Frank Colbert since 2013. I have found them to be the best in the business for their honesty and commitment to their craft. There is nothing worse than discovering an environmental issue that can affect the safe habitability of your home; there is nothing better than finding a vendor that can help navigate understanding where the issue came from and how to remedy it. Frank successfully removed cat urine from the slab of a 3,000 sq. ft. home when no other vendor could; he has assisted mold issues and was instrumental in helping identify a pipe burst in a slab foundation. Very professional, completely prepared and always presents a well thought out approach to remediation. Experienced with buyer investigations during an escrow, seller pre-listing inspections and insurance claims. I hope I don't need environmental services moving forward, but if I do Hidatsa is my first call. read more

Frank is a straight shooter, and very thorough. Would use him again and would recommend him to friends. He is communicative, and did a great job finding all the places we needed to work on to remediate mold. Very competent inspector. Also, reasonably priced - didn't overcharge or try to get us to do testing we didn't need. read more

I did some flooring work I probably should not have been doing and decided to have my flooring tested for asbestos before I go any further. I called Hidatsa testing and spoke with Frank and was able to setup an appointment for that day. Frank's prices are competitive and he knows his stuff. Not only that, he seems to really care about his clients. He gladly spent the time to answer all of my questions and convince me that I probably wasn't going to die anytime soon just because I took out asbestos tile in a couple of rooms. No unnecessary services or upsells here. Just great, straightforward service. I hopefully won't need to do mold or asbestos testing anytime soon, but if so I'll call Frank again. read more

Frank was fantastic. I called him during the inspection phase of my house buying process. He was out there the next day, and had results back in two days, rushing it because he was going out of town. He was knowledgable and professional. Frank did asbestos and lead testing, and during his sampling, noted that he didn't see any signs of mold and that a mold inspection was unnecessary - great! I highly recommend Frank for your testing needs. read more

Frank is awesome! He showed up on time, did a great job and was very knowledgeable. I was having some construction done on my house and there was a concern of asbestos under my floor tiles. He tested the floors and suggested that we test the walls as well since my is so old. The reports came back very quickly and I now have peace of mind that my home is free of asbestos. I highly recommend Hidatsa Testing and Frank for any asbestos concerns. read more

After unrelenting health issues and suspected mold in our rental unit, Frank came to the rescue. In all our interaction, he was very prompt, responsive, knowledgeable, professional, and caring. He inspected our rental home and recommended we report our concerns to the landlord. We are so thankful that Frank chose to not charge us for that initial inspection. I highly recommend him as a mold inspector. read more

Frank is a knowledgeable professional. He showed up not only on-time but 10 mins earlier than our appointment. He provided professional recommendation and inspection. He did not try to sell me any unnecessary service. He listened patently to our concerns and responded professionally. His service cost is very affordable. I would highly recommend his service to my friends. read more

Frank was so helpful and knowledgeable. I was concerned that I had mold in a bathroom vanity cabinet. He was able to assess it quickly and to my relief, we're mold free. If I needed a test done I would definitely use their service and will recommend them!!! read more

Frank was very knowledgeable and answered all my questions. I was concerned I might have mold in my room, but after examining my room Frank was very honest and assured me there was none. He did however find mold in areas where there was previous water damage. I would've liked to have gotten some air samples, but they were definitely out of my budget. read more

Frank knows mold and standard procedures for remediation. He will work with the remediation company but is not afraid to fail an inspection that does not meet current industry standards. I feel he really represented my interests and kept my home safe without demanding extreme remediation measures. read more
