"Thomas Candella did a great job identifying the source of the mold issue, managing and remediating the mold - this was my first experience with mold and Tom was very patient with all my questions. He was professional at all times - from the first call to Robert Kye, the owner to the last visit, putting up the drywall, painting and providing pictures for submission to the insurance - I highly recommend Certified Mold Removal, Inc for all your mold issues. Mold in the home is not healthy."

"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!"

"I just got done speaking to Spencer on the phone who was very generous with his time running through all the potential contaminant issues, breakdown of Oasis services, and was very candid on whether i should even proceed with any testing. If i do proceed I will certainly pick this company."

"I saw NAL East Environmental, read their Profile & was extremely impressed. Their Inspectors’ are Highly Educated Professionals. Words can’t describe how Grateful I am for Mark Stern & Joe Chairmonte. Testing was explained with Professionalism, Knowledge & Compassion. Mark is a Genuine Professional. He was Respectful & Kind as he explained and knew what should be tested. Joe was already set up. They were extremely thorough. After testing, Mark said, “Please call with any questions,” He was true to his word. After finding Acute Mold issues in Our Rental Home of 17+!years. Mark showed much care for Our well-being. It’s RARE to find a Co. with such Caring Inspectors w/High Moral Values, Yet, here they are!! I hired Mark & Joe again for Surface Testing. I’ve since referred Mark & Joe to Family. NAL East is The BEST! Thank you & Many Blessings to Mark & Joe. You are Amazing Assets to NAL Eastern & Our Community!! Jacqueline W., Yardley, PA"

Mold Testing and Remediation FAQs, answered by experts

In most cases, it is safe to return home after mold remediation is complete. You should follow your mold remediation technician’s recommendations, but most pros request that homeowners wait one day after the process is complete to move back in.

After returning home, be sure to carefully inspect the exposed areas for any remaining signs of mold spores. Contact the mold remediation company if you detect any lingering mold.

While an air purifier can trap mold spores and stop them from spreading around your home, it’s not the most effective solution for tackling the problem. Mold is caused by excess moisture and humidity, so there’s a good chance you have an issue somewhere else in your HVAC system that needs to be addressed.

Drywall can be toxic to the environment and to humans in some cases. As drywall breaks down in a landfill and comes in contact with other organic chemicals, it can create hydrogen sulfide gas or leach into the groundwater. Additionally, the CDC recommends methods for controlling the inhalation of drywall dust when handled. While the common ingredients of drywall—gypsum, silica, and mica—are naturally occurring, they can cause irritation in some humans.

Mold grows in areas with humidity levels above 60%, but ideal conditions for mold growth occur when humidity is between 70% and 90%, especially in poorly ventilated areas. To prevent mold growth, aim to maintain indoor humidity levels between 30% and 50% using dehumidifiers, proper ventilation, and temperature control. Regularly check your home's humidity with a hygrometer to help you monitor and avoid conditions conducive to mold.

It’s possible that installing solar panels can lead to mold on the roof. The panels themselves are not the issue. Problems caused by improper installation—such as roof leaks and mounts that aren’t sealed properly—can cause mold. Another potential cause of mold is debris accumulation under panels, which can trap moisture. If you live somewhere with extreme snow, rain, or hail, your home could be more prone to mold.
