Window Replacement for Colorado Homes

Old windows let in drafts, fog between the panes and fade in the high-altitude sun. Blue Peaks Roofing replaces windows for Front Range homeowners and can coordinate the work with your roof or siding project.

We start with a free consultation, measure your openings and walk you through the options that fit your home and budget.

Signs your windows need replacing

  • Fog or moisture between the panes, which usually means a failed seal
  • Drafts you can feel on a cold day, or rooms that never stay comfortable
  • Sashes that stick, will not lock or will not stay open
  • Cracked glass or damaged frames after a hail storm
  • Soft, rotted or warped frames and sills
  • Faded, chalky or cracked frames from years of sun

Built for the Front Range

Colorado considerations for new windows

Sun and UV

Strong sun at altitude fades and breaks down frame finishes and interior furnishings. Low-E glass coatings help limit heat gain and UV coming through the glass.

Temperature swings

Big swings between day and night make frames expand and contract. Frame material and a careful installation with proper sealing help windows hold up.

Hail

Hail can crack glass, tear screens and dent exterior cladding. After a storm, windows are worth checking along with the roof and gutters.

Energy efficiency

Look at the NFRC label, which lists ratings such as U-factor and solar heat gain coefficient, and ENERGY STAR certification for your climate region.

Know your choices

Frame materials and installation types

Vinyl

Usually the most budget-friendly choice. Low maintenance, with limited color options on some product lines.

Fiberglass

Strong and stable through temperature swings, and can be painted. Typically costs more than vinyl.

Wood and clad wood

A traditional look inside, with exterior cladding to cut down on maintenance. Usually the highest cost.

Insert replacement

The new window fits inside the existing frame. Faster and less disruptive when the old frame is sound.

Full-frame replacement

The old window comes out down to the rough opening. The right call when frames are rotted or you want to change size or style.

Plan the whole exterior

Replacing windows during a roof or siding project

If you are planning a new roof or new siding, it can make sense to look at windows at the same time so flashing and trim tie together cleanly and you deal with one coordinated schedule. Read when to replace windows during a reroof and siding options for the Colorado climate.

Permit requirements for window replacement vary by city and county. We will tell you what applies to your project. See all of our windows and siding services.

How it works

Our window replacement process

  1. Free consultation. We look at your current windows, talk through what is bothering you and note any frame damage.
  2. Measure and options. We measure each opening and explain frame, glass and installation options with written pricing.
  3. Order. Windows are made to size, so there is a lead time between ordering and installation.
  4. Installation. Old units come out, openings are checked, and new windows are set, sealed, insulated and trimmed.
  5. Walkthrough. We check operation and locks with you and clean up before we leave.
Common questions

Window replacement FAQ

How long does window installation take?

It depends on the number of windows and the installation type. Insert replacements go faster than full-frame work. We give you a schedule with your estimate.

Can you replace just a few windows?

Yes. Some homeowners start with the worst windows and replace the rest later.

Should I replace windows before or after a new roof?

It depends on the condition of both. Our guide on replacing windows during a reroof walks through the trade-offs.

Is the consultation free?

Yes. We measure, explain the options and give you written pricing with no obligation.
