Full Window Replacement

Drafty, foggy or hard-to-open windows? It’s time.

Colorado puts windows through a lot — intense sun, hail, snow and big temperature swings. We replace tired builder-grade windows with high-performance units sized and specced for the Front Range — installed by certified crews from a Pella Platinum Certified Contractor.

  • Lower energy bills & real comfort — fewer drafts in winter, less heat gain in summer.
  • Built for the hail corridor — glazing and framing chosen for Front Range weather.
  • Honest recommendations — sometimes just new glass will do, and we’ll tell you.
  • Clean, on-schedule installs — we show up when we say we will and clean up after.
What We Do

Everything your home’s openings need.

From a single cracked pane to every window in the house — plus doors, storm repair and exterior painting to finish the job.

Earned distinction

Pella Platinum Certified Contractor. Earned, not claimed.

KV Windows worked hard to earn Pella Platinum Certified Contractor status — Pella’s top contractor tier. Per Pella, Platinum status requires annual certification and qualifying Pella product purchases. Contractors at Certified level and above must also pass a background check, provide insurance, meet local licensing and employment requirements, and complete annual certification training plus local installation training or an audit.

For homeowners, that means a Pella Platinum Certified Contractor with certified installers — held to Pella’s certification standards, not just selling a brand name. Pella describes its Platinum Contractor Summit as representing the top 1% of contractors nationwide.

I had several window companies look at replacing a broken window at my house and ultimately went with Matt at KV Windows because he was the most knowledgeable and responsive… I 100% recommend Matt and KV Windows to anyone looking for a knowledgeable and fair window company.

We had a wonderful experience with KV Windows. The team was organized, easy to work with, and very knowledgeable. They helped me select the perfect replacement window for my room!

Our master bedroom windows were cloudy, fading and we were afraid that replacing them was the only option. KV windows came out and gave us a price to replace just the glass… After they were done the windows look brand new again.

Very happy with the window and screen installation process. They were very professional and considerate. I really appreciated how well they cleaned up after the work too. I love my new window, it is perfect!
