Get Started


Marc Cowan, who started The Highland Window Company in 2002, has built his exterior renovation business on a solid foundation of the highest quality materials, excellent workmanship, and extremely competitive pricing. Highland’s window replacements, siding, and entry doors, installed with a full lifetime transferrable warranty (details available upon request) have been delighting customers for years. As a result, The Highland Window Company has established itself as one of the premier home improvement companies in Connecticut, with a long roster of satisfied clients.

One of the things that sets the Highland Window Company apart from other home-improvement companies is the personal attention given to customers. Marc takes the time to learn about the customers and then, using his extensive experience, makes appropriate recommendations.

Fully licensed and insured, Highland covers the entire state of Connecticut, providing no-obligation estimates and in-home demonstrations seven days a week. Their professional team of installers offers completely reliable and expert workmanship while treating every home with respect. No job is considered finished unless the customer is completely satisfied.

An accredited business with the Better Business Bureau, The Highland Window Company offers discounts to first time buyers and senior citizens, and also has full financing available.
