Our History

Commercial Storefront Services started in 1994 and has since grown into a full service custom fabrication and contract glazing company. Owner Ken Jeski launched the company in his home town of South Windsor, Connecticut, in a 900 square foot space with Ken as the sole employee.

Just one year later, Ken outgrew the original facility and moved to a larger facility in town with the capability of future expansion.

As time progressed, more and more contractors gravitated towards Commercial Storefronts due to its reputation and success, and the business started to really grow. After a number of expansions, Ken drew up plans for a brand new state-of-the-art 8,500 sq ft facility, still remaining in South Windsor.

In December of 2013, CSSI moved into its brand new state-of-the-art fabrication facility with seven full time fabricators. This was in addition to the already thriving business of commercial glazing and installation, with seven full time employees there as well.

Still in South Windsor and with even more space to grow, Ken has continued to expand his operations to handle the increasing demand from major commercial clients requiring the superior quality and work ethic of Commercial Storefront Services.
