Lifetime Windows & Siding was started in a one-bedroom Denver apartment in 2009 by Peter Svedin. He had a Discover card with a credit line of $7,000. Given his limited resources, he began selling windows door-to-door.

Today, Lifetime has an office in Denver and Phoenix, employs over 100 people, and is on track to generate $70 million in revenue this year.

Our recent accolades include:

  • #1 Infinity from Marvin window and door dealer in the U.S.
  • #1 James Hardie siding dealer in the Western U.S.
  • Recognized by ColoradoBIZ magazine as a Top Colorado company in 2019
  • Ranked #85 on Remodeler Magazine’s Top 500 list in 2019
  • Recognized by the Denver Business Journal as one of Colorado’s fastest growing companies in 2018

Helping the Community

Lifetime has been supporting the local community since we opened our doors in 2009.

Stout Street Foundation

Life is tough for residents when they enter Stout Street. Lifetime provides an opportunity to get them back on track with employment that helps pay for their stay at the facility.

Food Bank of the Rockies

Our newest partner, Food Bank of the Rockies, distributes over 56 million meals each year to people in need. When the pandemic hit 30% of their food recipients had never needed the food bank’s help before. So, Lifetime stepped in to help out.
