Our Story
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.

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.

Quality before Quantity has always been the mission of Lifetime Windows and Siding. We want each of our customers to be completely satisfied with the products and services they have purchased from us, which is why we offer a lifetime warranty on everything we sell. We are committed to making your home more energy efficient; all of our products meet the government backed ENERGY STAR rating, which qualify products that meet the highest energy efficiency standards.

We are proud of our commitment to supporting local business, all of our products are built in the US by a partnership of reliable manufacturers and installed by our team of factory trained craftsmen.

Peter Svedin, Founder and CEO
Peter has extensive experience in sales and customer service that he combined with an entrepreneurial spirit that came from owning his first business at the age of 20. He immigrated to the US in 2001 from Sweden, and after completing his marketing degree from Hawaii Pacific University, he relocated to Denver. Peter got into the home-improvement industry by accident, but learned quickly by working for companies specializing in windows and siding. He soon realized that the industry was lacking customer service, quality installation and ways to market products. He partnered with Jason Lewis in 2009 and formed Lifetime Windows and Siding LLC out of his apartment, with the slogan “quality before quantity.”

Jason Lewis, Founder and COO
A native to Colorado, Jason has been involved in the window and siding business most of his life. His family owned a Denver window company established in 1986. He still remembers being 10 years old and his dad bringing home a heat lamp to show the family the amazing new glass coating called Soft Coat Low E. He started working with his dad in 2005 doing sales, installations and learning everything about the industry. When his father retired in 2009, Jason decided to start his own company with Peter Svedin.
