Estates Windows was founded in 1977 by respected Highwood mason contractor Reno Fabbri. Ultimately, ownership passed to the family’s equally service-oriented next generation, led by Dennis Valentini.

Estates Windows opted to supply the best product possible and opened a Marvin Windows and Door Dealership in 1992. The dealership’s customer base evolved into a list of who’s who of Chicagoland architects, builders, and homeowners. Realizing the need for something even more special, Estates Windows launched the 2007 opening of Chicagoland’s only Marvin Design Gallery.
