"Overall was good for what the service is. The technician was a postal worker and home inspector. So mold test company appears to be brokers. Their pricing was competitive from other quotes I received but I honestly think it was pricey for time spent and what they do. But like I said the price was pretty standard from the companies I called, in my opinion. But the technician was attentive and knowledgeable, and friendly."

"I hired Restoration Services to inspect an odor issue in my basement. They tested the air and surfaces and determined that we had mold. They remediated the mold and then performed post testing to confirm. The mold was completely completely gone. I feel very comfortable that our mold issue has been resolved."

"Jeremiah came out and tested the air and moisture and other items to determine if I had mold in my basement. After getting the test results there was evidence of mold and he recommended a company that provides a do it yourself kit for mold remediation. (Not cheap). After getting the items and realizing that there was more work, it would have been better for me to let my insurance company handle this as I do have coverage for mold/fungi. Though having a professional do the work is expensive, from what Jeremiah mentioned, it does not guarantee that the work will be complete or the source of the problem taken care of. He mentioned most companies will take care of the mold but not necessarily the cause of the mold. For this I would have to contact another company."

"Smart Environmental has excellent customer service and incredibly honest people. They saved us thousands of dollars by stressing the importance of testing our old vermiculite insulation rather than assuming it had asbestos. While another company took a look at our attic and gave us a quote for over $3,000 of asbestos remediation, Pony described that many inspectors see old insulation and assume it is asbestos, but that is not always the case. Pony took a sample from our attic, got it tested for us, and promptly sent us the negative test results the next day. We could not be more grateful for Ponys honesty and the diligence he took in actually testing our insulation instead of just assuming we needed a costly remediation."

"I cannot thank Spencer enough! He was very patient with me, as I have been suffering terribly. I knew I had toxic mold in my apartment. Spencer did lot's of test. He spent 2.5 hours working, testing air, taking samples and answering my questions. He listened to me. He was so compassionate about what I have been going through for the past couple years. I was asking allot of questions and he was not rushing me, to just get in and get out. I really needed to understand and clarify lot's of things. Spencer was that clarity I have been looking for. He really helped me understand how bad water damage toxic mold can be. I really wasn't crazy! I'll tell you, I have reached out to quite a few mold inspection companies and I knew the minute I first spoke to him, he was the guy I needed to do my testing. Spencer came highly recommended from allot of friends on Facebook. If you want integrity, honesty, direction, clarity, understanding, a very thorough inspection and just a great guy, give him a call. I thank God, that I found him. What a blessing Thank you Spencer"

Mold Testing and Remediation FAQs, answered by experts

Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. The chances of mold developing depend on several factors, including the severity of the damage and how quickly the area is cleaned and dried. To prevent mold, you must act quickly—ideally within the first 24 hours. Clean up all water and thoroughly dry the affected area. If the damage is extensive, you were unable to address it immediately, or you suspect mold has already started to grow, it is best to assume it is present and hire a professional mold inspector or removal expert to assess the situation.

Mold doesn’t take long to form, especially in dark, isolated areas like under the floorboards, where you’re less likely to know it’s wet in the first place. Mold can take root and proliferate in just 24 to 48 hours, but it can be up to a week before you start to notice funky smells. 

According to the EPA, mold grows within 24 to 48 hours if left untreated after a water leak. So unless you notice the leak and stop it right away, you only have a day or so before mold is a real concern. If you don’t notice the leak, it can take about three weeks for the mold spores to become visible. That means you’ve likely had an active mold infection for a few weeks by the time you notice discoloration.

Professionals suggest through ventilation, source removal, or filtration systems.

There are different types of mold, and not all humans are the same. For example, a more toxic type of mold may have less of an effect on a healthy person than a less toxic mold in the home of someone who is immunocompromised. If you recognize any symptoms of mold poisoning—sinus issues, brain fog, respiratory distress, constraint cough, migraines, or any others—call your doctor or go to the hospital before you attempt any removal.
