"The crew of four did an excellent job, they were very polite and professional and cleaned up all debris before leaving. The project manager Guy was onsite to insure all went well. It was a very good experience that took only about 4 hours to complete and I highly recommend this company. Guy issued me documentation the following week that the mold remediation was completed and that the attic ecology was back to normal."

"Extremely well. I hired Impresair to remove a layer of asbestos shingles from the exterior of my house. But, as the asbestos shingles were gradually removed, we discovered that the house also had a second layer of asphalt shingles under the asbestos shingle layer that was visible. This meant that a second, and unexpected, layer of siding also needed to be removed and hauled away. No problem for Impresair. They just brought in additional workers to complete the extra removal work on schedule...and finished the work on a day when we were experiencing showers for the entire day. They simply worked through the showers. Impresair is a very professional company and I strongly recommend them to anyone who is interested in removing asbestos shingles from an old house. They arrived on time and the crew worked very diligently for three long days. When the siding was all off, they cleaned up the job site very well and made every attempt to locate any stray nails that might have been overlooked during the clean up work. A week later, they sent me a number of official documents for my retention that serve to substantiate that asbestos had been remediated successfully at my address. I am truly delighted with the results and would definitely hire them again for any future asbestos removal work that I might need."

"Fantastic service. Had high mold counts for my Dads house. Other companies were 2-3 times higher and we had to vacate the house for 5 days. Rey came in treated the house and we were back the next day. Had an independent mold tester come in after remediation and the results were well below acceptable levels. My Dads health has improved dramatically and has changed his quality of life: Thank you Rey!"

"Jason came out to determine if we had mold in our attic based on some black marks we were seeing on our plywood, a contractor doing some work mentioned that it may be mold and that we should have it checked. We had another mold inspection company come out, confirm on visual inspection it was mold, comment they did not need to do an air test as there was no question, took some samples of the mold itself and our air ducts and said they would be in touch the next day with results. In the meantime, they sent their remediation person to give us a proposal for remediating it. We then never heard from them with the results and also had wanted to get another opinion and proposal to compare cost of proposals. This other company also charged us $ upon inspection and did not deliver the results. Therefore, we called up indoor environment (we were also looking for a "greener" option). Jason came out the next day to take a look at our mold to provide a remediation proposal. He stated the inspection for remediation is no charge unless he does air quality tests and then clearly explained what the charge would be for a single test and the control test. He arrived on time and took a look in our attic and said that we did not have a mold problem that it was just water staining. He was very confident about this and confirmed that we did not have a mold problem. He was very detailed in his explanations and did not rush out given that he no longer had a "job" to remediate. He spent a good deal of time with us answering all of our questions. If you need somebody you can trust, please call Indoor Environmental, we feel that they are in the business for the right reasons and very trustworthy. It was refreshing after what we had been though to feel that there are folks out there you can rely on during a vulnerable and stressful time."

Biohazard Remediation FAQs, answered by experts

Usually, when you have mold, you will notice that your indoor air quality isn’t what it should be. You might notice dank odors, for instance, coming from your carpet, and it may feel damp or spongy. Or you may find that your family members are showing more allergy symptoms than usual, from coughing and sneezing to itchy, watery eyes.

And, of course, if you’ve recently experienced flooding or you live in a particularly humid environment, that’s a good sign you’re at risk for mold growth.

Several factors contribute to the persistent growth of mold in vents, with excess moisture being the most common culprit. Consistent mold formation in vents indicates an ongoing moisture problem within the HVAC system or its surroundings, likely caused by condensation on cool surfaces in areas with high humidity. Moisture accumulation can also result from leaks in ductwork, inadequate ventilation, or insufficient insulation, creating an environment favorable for mold growth. Regular inspections, addressing potential sources of moisture, maintaining proper ventilation, and routine HVAC maintenance can help prevent the recurrence of mold in vents. If the issue persists, seek professional assistance to identify and rectify the underlying problems.

Yes, a one-time water leak can cause mold. Depending on the conditions, mold can begin to grow within 12 to 48 hours. The risk increases with the severity of the leak, high humidity, and when water soaks into absorbent materials like drywall. To prevent mold growth, stop the leak immediately and ensure the area is dried completely; running a blower fan for 24 hours is recommended. If you do notice mold, it's best to call a mold removal specialist to address the situation.

Many types of mold spores and fungi spores are constantly present in the air, but they need a friendly surface and moisture to grow. Should some of these spores land on paper or wood with significant moisture present—such as drywall with a paper cover that is soaking up water from a leak—mold or fungi could begin growing. Dampness from leaky pipes, condensation on windows, leaks in a roof, flooding in a basement, or high, prolonged humidity in a small area all can create the excess moisture that mold and fungi need to grow in your home.

Usually several days, depending on the extent of contamination.
