Our Story

Why Five Seasons?

We all know the big four: Winter. Spring. Summer. Fall. But what about that other season? The one that’s a little less predictable: Snow in May. Hail in August. A freak windstorm or merciless heatwave. That’s the fifth season - The unexpected weather we’ve come to expect.

When it comes to your home, it’s paramount to have specific windows for all seasons. Windows that are: 


  • Strong enough to protect your home.
  • Beautiful enough to increase its value.
  • Easy to open and close.
  • Energy-efficient and affordable.


We’ll worry about the ins and out’s of providing expert service, so you can focus on things that make you happy -like enjoying Colorado weather. But don’t forget, prepare for the unpredictable - the fifth season!

Meet the Owner

John Kroeger, Founder of Five Seasons Windows & Doors

John Kroeger — Founder & Business Owner

John Kroeger founded Five Seasons Windows & Doors to bring honesty, craftsmanship, and genuine care back to the home improvement industry. The name “Five Seasons” reflects Colorado’s unpredictable weather — and John’s mission to prepare homes to withstand all of it.

Even as the company has grown, John still visits job sites, meets with customers, and personally responds to every review — good or bad. His philosophy is simple: never use gimmicks, always provide the best quote the first time, and let the quality of the work speak for itself.

Under John’s leadership, the team does more than replace windows. They protect home value, comfort, and energy efficiency while specializing in Marvin, Anlin, and other premium brands. Five Seasons Windows and Doors also provides expert James Hardie siding upgrades, delivering lasting results across Colorado’s Front Range and mountain towns.

Outside of work, John is a husband, a proud dad to a toddler, and a dog-dad to Penny. In 2025, the Denver Broncos recognized his company as their Official Broncos Small Business Partner, a distinction that affirmed what John has built: a company that Colorado homeowners can trust.
