Sto Certified Craftsmanship. Extended Coverage. 

Sto Corp. is proud to collaborate with the Association of the Walls and Ceiling Industry (AWCI) to enhance quality assurance in EIFS (Exterior Insulation and Finish Systems) applications. As of July 2025, qualified EIFSmart applicators installing StoTherm® systems are eligible for a two-year extension on Sto’s system warranty, along with limited labour coverage.

This program helps contractors differentiate themselves through certified craftsmanship while offering architects and owners added confidence in the systems they specify. This partnership reinforces Sto’s ongoing commitment to quality, accountability, and higher industry standards.
