Lifetime Windows and Siding began as a partnership between Jason Lewis and Peter Svedin in 2009. Combining the high quality product and service standards Jason learned from his family window business, and Peter’s extensive sales and customer service experience, and adding in an even higher lifetime service and labor guarantee, the two entrepreneurs knew they had a winning formula. Working out of a one bedroom apartment, armed with a detailed knowledge of the business and an unshakable belief that people CAN receive the best service at the best price, Jason and Peter hit the streets, learn more. They did anything they could to promote their new business for more website, like knocking on doors around job sites to let people know about the quality they provided.

Due to their their eagerness to learn, utilise the latest innovations, exceptional customer service, quality installations, and tireless promotion; Lifetime Windows and Siding has grown into one of the largest and most reputable Denver windows companies. By 2016 Lifetime had grown to a $15 million corporation with 30 employees, but it still retains its core value of quality before quantity.
