How can water get behind the EIFS barrier?
Water can intrude behind EFIS through windows, where windows and EIFS meet, where EIFS and roof lines meet, through intrusions in the EIFS for gas lines, electrical conduits and fixtures, where doors meet EIFS and where decks meet EIFS. Although good building practice calls for application of sealants and flashings to stop water from intruding through these pathways, sometimes contractors fail to properly install these building facets.
