"Ongoing water intrusion from our windows over the years led to mold issues throughout several rooms in the house. After bringing out three different companies to evaluate the situation, Steven and the team at Nexgen Property Restoration stood out right away. They were fair on pricing and offered a non insurance discount since we chose to handle everything out of pocket. With multiple areas needing to be opened up, that savings really helped. The remediation process was handled professionally from start to finish and the quality of work gave us the confidence to move forward with them for reconstruction as well. Having one company manage everything made the process a lot easier. The final result came out great and their warranty gives us peace of mind moving forward. Definitely recommend Nexgen if you?re dealing with paying out of pocket"

Prompt removal and prevention measures are essential, regardless of mold type, to maintain a healthy indoor environment.

While surface mold can be effectively eradicated with proper cleaning and preventative measures, it's difficult to guarantee its non-recurrence under favorable conditions. To prevent mold from reappearing, it is important to identify and resolve the root cause of the moisture that triggered mold growth initially.

Ensuring appropriate ventilation and a dry environment, or consider applying protective finishes such as sealant, varnish, or paint to prevent future moisture penetration and mold growth. Consistently inspect and maintain the area to keep the wood free from mold in the long term.
