"Charles Schwartz was available immediately for us when we called. We met him the next day, and he did an extremely thorough mold inspection/assessment of the house we were planning to buy. He tested the surfaces and the air for mold. We were able to determine what type of mold it was, where it was located, the extent of the problem, the cause of the problem and a plan to remediate. He was highly professional and scientific. He was patient with us, available to answer our questions, and thorough in his report. We felt very much able to trust his advice, and now have a plan in terms of moving forward with what we will need the seller to do in order to properly remediate the problem. We would definitely highly recommend his services."

"No one wants to find mold in their home (or in our case, the home we were buying), but everyone wants to find good, reliable, knowledgeable people to help them, and Johnnie definitely fits the bill. We were referred to Johnnie and got him on-site the very next day he was very accommodating. He spent a ton of time not only carefully working in the house, but gave generously of his time to explain things to us thoroughly. He was very honest, gave us his unfiltered assessment based on his expertise (which we appreciated), and we can not recommend him enough. If you are looking for someone who is personable, reliable, reasonably priced, and really good at their job, hire him, you will not be disappointed."

"I was concerned about a mold problem and sent pictures to Tal after reading reviews on Home Advisor. He studied the situation and got back to me right away, reassuring me that it was not necessary for me to spend money on testing because it did not appear to be a serious problem. I am very impressed by his honesty and integrity. If we ever do need cleaning and restoration services, I would go with Ace for sure."

"I used AAA lead professional for asbestos testing and remediation. Josephs company was professional and demonstrated a lot of experience. AAA tested my home, found asbestos and did the remediation as quoted in a timely fashion. I highly recommend Joseph and his team at AAA."

"Project: Remove damaged kitchen cabinets and sheet rock caused by water damage. They came in with a crew of workers and removed the cabinets and drywall and insulation. Performed Mold Remediation where needed. Set up blowers to dry everything out. Very professional and reliable. They cleaned every thing up and left the area spotless. Would highly recommend."

"When I initially discovered I might have had asbestos in my cracked flooring, I was very anxious and scared. I got connected with Christian the same night the discovery happened. He answered a lot of my panicked questions with calm and patience. As frantic as I was he was very understanding and helpful. My experience with Christian was great and I definitely would recommend him. I contacted another asbestos tester before reaching Christian, and they treated me with disrespect and could not care less. If you want someone who is understanding and attentive to your situation, dont look anywhere else! Thanks again Christian!"

Mold Testing and Remediation FAQs, answered by experts

Yes. You should use this product in a well-ventilated area because the fumes can be harmful. In addition, the product is poisonous if swallowed, so keep it out of reach of children. Wood finishing products that are oil based can cause irritation to your skin, so you should always wear gloves when handling it.

A stain from a water leak will usually be brown and concentrated in a single area where the water is originating from. You may find it under a damaged section of roof, under an upstairs bathroom, or beneath your HVAC system. Stains from condensation are more likely to be widespread since they don’t come from a single point of water intrusion. Condensation stains also look blotchy and may smell musty, and they won’t be concentrated in a single area on your ceiling.

Running an air conditioner with mold is not safe because it can spread harmful mold spores throughout your home. Exposure to these spores can trigger various health problems, including respiratory issues, allergies, coughing, wheezing, sneezing, itchy eyes, and a sore throat. It may also aggravate asthma in household members. Continued exposure can increase the risk of more serious illnesses like sinus infections, pneumonia, and bronchitis. If you suspect mold in your air conditioner, you should stop using the system until it has been properly cleaned to avoid health risks and further contamination.

The cost for mold remediation typically ranges from $1,125 to $3,350, with a national average of around $2,400. The final price depends on various factors, including the location and square footage of the affected area, the type of mold, and local labor costs.

Additional factors that influence the total cost include:

  • Extent of Damage: The overall price can increase significantly if extensive repairs are needed after mold removal, such as replacing large sections of drywall. Removing mold from a small area of drywall might cost between $300 and $825, but full wall replacement is more expensive.

  • Health Risks: The cost is also justified by the health risks associated with toxic mold, which can cause respiratory distress, act as carcinogens, or even damage the nervous system.

  • Comprehensive Service: Remediation involves not only removing the mold but also addressing the moisture issues that caused it to prevent future growth.

  • Testing and Air Quality: The need for safety testing and measures to improve indoor air quality can also add to the cost.

For an accurate estimate, it is best to consult a mold removal specialist who can assess the specifics of your situation.

Removing mold yourself can be dangerous. Always wear protective gear to cover your skin, face, and eyes, and wear a respiratory mask to protect your lungs. It is most recommended to only remove small areas of mold on your own and leave large mold growth to professionals. Mold growth can also be persistent. Without addressing the root cause, DIY surface cleaning can be ineffective and temporary.
