Lifetime Window Siding Replacement & Installation Company in Denver.

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. They did anything they could to promote their new business, like knocking on doors around job sites to let people know about the quality they provided.
