NorthStar Solutions LLC's website says its water and mold damage tear-outs cut away only what is needed, keeping unaffected materials intact for the rebuild. A recent customer said Daniel came out to the property the same week they called, provided a free estimate and had the mold remediated within a week. That customer said he made sure everything was properly ventilated and that their animals were safe from what he was using to kill the mold. A recent customer who needed mold remediation said they thoroughly treated the space and were fair with their rates. A 2023 customer said Daniel and the team had mold in their basement remediated within a week of calling. A 2023 customer said the business was hired to remove mold from a shed. A 2024 customer said Dan showed before and after pictures because the area had been bombed as a final step. A 2022 customer said the company used natural and non-toxic products and offered a 1-year transferable warranty. A 2022 customer with mold in the basement said he came out within a day, came back within 2 days and took care of the mold problems in the house.

If you need mold remediation, this is the company to call. They did an amazing job thoroughly treating our space. Not only are they great at what they do, but they are also exceptionally nice and fair with their rates. After comparing them to a few other companies, I can confidently say they are the absolute best choice around.

After calling multiple mold companies and speaking with receptionists, I knew I had a winner when the owner of Mazyck Mold Services answered the phone. Daniel was very knowledgable, he came out to my property the same week I called him and provided me with a free estimate. Within a week I had an estimate and my mold remediated, no mess, no hassle, no cleanup for me. He made sure everything was properly ventilated and took the time to make sure our animals were in good spots and safe from anything he was using to kill our mold. I cannot recommend Daniel enough. He made our project feel absolutely painless, not to mention the warranty he provides for his service to give us peace of mind. Thank you so much Dan!

Dan was so pleasant to work with. He responded quickly, never left me hanging. Arrived right on time. I had some other estimates and his pricing was super. The process did not take vert long and he showed me before and after pictures because the area had been “bombed” as a final step and the product was dissipating.
