Absolutely stunning casement windows, they completely changed the look and feel of our living room. The crew was respectful, tidy, and done ahead of schedule.

Had them out to service my windows and doors installed 15 years ago. Service tech was excellent, very knowledgeable. EPIC stands behind their work long term, and that says everything about a company.

Best home investment we've made in 10 years. EPIC was honest about what we needed (and what we didn't). That kind of integrity is rare. Will absolutely use them again.

Our energy bill went down $80 the first month after the new windows. The team was in and out in one day. Best decision we made this year.
