Mirasol Phase 1 Deck Remediations

Phase 1 Mirasol Senior Community in Loveland, CO had severe moisture intrusion issues in all of their decks from improper waterproofing when the building was originally developed. Signs of such problems were investigated and after partial demolition, it was found that the OSB/framing was destroyed in places from moisture and was deemed unsafe for future use. Because of this all of the decks needed to be removed completely and re-built from scratch.

Materials installed by Monarch Stucco Inc in the re-construction of these decks.
