Mold Prevention

TruRenu uses non-toxic mold-resistant sealants to pretreat building materials during construction of wood frame structures. These products help to protect the investment in your home and your family's health. The sealants are backed by a 25-year transferable manufacturer's warranty. 


Our professional staff works with homeowners and builders to proactively address challenging spaces such as kitchens, baths, laundry rooms, basements, and other areas at risk for mold. TruRenu can develop strategies for both preventing and controlling the environmental conditions that promote mold growth and the resultant unhealthy air.


Builder Programs

TruRenu offers a builder program to apply Structure Guard, a professional-grade, fast-drying polymeric wood paint and sealer designed to prevent mold and mildew growth from forming on wood surfaces. It can also be used on framing lumber, engineered lumber, trusses, millwork, pallets, decks, and other above-ground applications. When Structure Guard has cured, the treated surfaces are resistant to both mold and mildew.

​When treating either residential or commercial buildings under construction, Structure Guard is best applied just after the dried-in stage and before mechanicals, doors, windows, and insulation are installed.

The best prevention strategies control moisture and address specific structural issues while being cost effective. TruRenu services include:

  • Structural pretreatments, such as Structure Guard

  • Commercial sump pump installations

  • Encapsulation of crawlspaces

  • Dehumidifier installation

  • Exhaust ventilators

  • Modifications to gutters and drains
