Radon Mitigation Before & After Photos

During a real estate transaction - an inspection turns up what needs to be fixed with a property. This crawlspace was affected by a flood caused by a drywall screw in the pumbing in the bathroom above. The existing Radon System was not properly inslalled - the fan was in the crawlsapce (potential for radon to leak from the fan), the liner was sealed over the drywall and studs (trapping moisture and creating conditions conducive to microbial growth/structural damage), and the exteriror Radon vent pipe was only terminated 2' above the ground next to a window (potential for back drafting Radon into the home). We removed the moldy drywall firewall & insulation, cleaned and dried the wooden structural elements, installed a proper Radon/moisture mitigation system - replacing the liner and sealing it to the concrete, moving the fan to the exteriror of the structure, and running the vent stack to terminate above the roof. We replaced the fire wall with 5/8" drywall, closed the vent and air sealed the perimeter rim assembly, and reinsulated the subfloor. We also installed a SmartDrain with a WaterWatch alarm to notify the future homowners of a plumbing leak. We were able to solve all these issues, which allowed the buyer and seller to close on the propery.
