Window Replacement vs. Repair in Denver & Colorado Springs

For most of us in Denver and El Paso counties, a broken window is a big problem because we have extremes in weather. Some days it feels like the sun is perched atop our roofs. Other days we wonder how much more deep-freeze we can take.

A broken window expense includes the energy loss we’re paying for every month. When cost is a factor, is it better to repair or replace a window?

You can repair a window if you have cracked or broken single-pane glass. Repairing a single-pane glass window “is a serious time commitment,” says one glass pro. Without being defeatist, if you have single-pane windows in Colorado, you’re already losing money.

Replacement is necessary if:

  • The window mullions (vertical wood strips separating glass panes) are letting air in/out and are fake.
  • The window was poorly installed.
  • The windows have a major water leak.
  • The windows have visible condensation or are foggy.
  • There are structural problems:
    • Difficulty opening/closing
    • Drafts
    • Frames shrinking, bent/warped
    • Locks/latches don’t work
    • Rotten/pest-infested wood

Window replacement offers a better long-term solution and long-term savings. Stopping the costly energy loss will save on monthly bills. And Zen Windows Denver’s most economical window replacement features double-pane, high-performance glass that qualifies for federal energy tax credits.

Our Replacement Windows Are Made for High Altitude

The elevation in Denver requires a special type of window. Higher elevation can weaken window seals, create efficiency issues, and make it harder for the window to stay in its spot. Zen Windows Denver understands this, and we offer replacement windows specifically designed for high altitudes.

Our windows have quality vinyl and excellent seals to withstand the demands of our local environment. We use multiple panes of glass to ensure enough room for expansion, even in the cold Colorado winters, so your heated air stays safely inside your home.

Window Replacement FAQ

Do you have questions about replacement windows? Check out these common questions and answers from the team at Zen Windows Denver.

What are some benefits of window replacement?

Replacing your windows can help lower your energy bills and improve your home’s curb appeal. It can also give you an easier-to-maintain option for your home, and it may increase your home’s resale value.

What factors impact the cost of replacement windows?

The cost of replacement windows is affected by the window style, the glass you choose, and the frame material. The size of the window also impacts its cost. Zen Windows Denver will help you select windows that meet your goals for your home and reduce your potential energy costs while also fitting into your budget.

Should I replace all of my windows at the same time?

This depends on your needs, as sometimes you have just one or two windows that aren’t serving you well or are broken, and in this case, a single window replacement makes sense. Replacing all the windows simultaneously can improve your home’s efficiency, but it will cost more initially.

How long does window replacement usually take?

It takes about an hour to replace one window. The length of time for window replacement will depend on how many windows you’re having installed.

How should I prepare my house for window replacement?

Prepare the walls around the window by taking off window treatments and artwork hanging on them. Cover furnishings with blankets to protect them from dust. Ensure the floor space around each window is cleared of furniture so the window installers can access the window.
