Replacement Windows and Doors

We have been building outdoor living spaces for Colorado families for four generations. This month we are adding something new: windows and doors.

It is a natural fit. We are already the crew homeowners call when the exterior of their house needs to survive Colorado, and windows and doors are the single biggest weak point in most Front Range homes. If you have ever stood next to a window in January and felt the cold pouring off it, you already know.

Here is what we have learned matters most — and what most homeowners never get told.

Colorado Is Genuinely Hard on Windows

This is not sales talk. Our climate stacks four different stresses on top of each other:

• Altitude. Colorado Springs sits at roughly 6,035 feet. Thinner air outside means a real pressure difference across a sealed window.
• UV exposure. More intense sunlight at elevation chalks vinyl, fades finishes and breaks down cheap seals faster than it would at sea level.
• Freeze-thaw swings. A 40-degree change in a single day is normal here. Everything expands and contracts, over and over.
• Hail and wind. We are in the middle of Hail Alley, and Monument and Black Forest see wind loads that flat-landers do not plan for.

The Altitude Detail Almost Nobody Explains

This is the one worth reading twice.

Most double- and triple-pane windows are sealed insulating glass units, and most are built at or near sea level. When that sealed unit gets trucked up to 6,000 feet, the gas trapped between the panes is now at higher pressure than the thin air around it — so it pushes outward. Hard. The industry rule of thumb is that a 2,000-foot elevation gain creates about one PSI of pressure difference, which on a standard window adds up to over a thousand pounds of outward force.

Left alone, that shows up as bowed glass, warped-looking reflections, stressed seals, and eventually fogging between the panes.

The fix is a tiny capillary tube — sometimes called a breather tube — built into the glass unit so the pressure can equalize. Industry guidance calls for these at roughly 5,000 feet and up, which covers every home we serve, from Briargate to Castle Rock.

If a window company quotes your house without ever mentioning high-altitude glass, that is your signal to ask more questions.

What the Label Should Actually Say

Skip the brochure adjectives. Every legitimate window carries an NFRC label with real numbers on it:

• U-factor. How well it resists heat loss. Lower is better. Colorado has a statewide efficiency standard for windows sold here, so make sure whatever you are quoted meets the current requirement.
• SHGC (Solar Heat Gain Coefficient). How much solar heat comes through. In our climate you generally want some winter solar gain, not zero — this is a balance, not a “lower is always better” number.
• Climate zone certification. Colorado requires the Northern Climate Zone qualification. A window certified only for a milder zone does not cut it here, even if it sounds efficient.

About That Federal Tax Credit

You may still see ads promising a federal tax credit on new windows. Be careful — the federal Energy Efficient Home Improvement Credit expired at the end of 2025. If your windows were installed by December 31, 2025, you may still be able to claim it on that year’s return, but a project installed in 2026 does not qualify.

We would rather tell you that up front than let you find out at tax time. Talk to your tax professional about your own situation, and check with your utility — local rebate programs sometimes still exist even when the federal credit does not.

Doors Are Half the Equation

An entry door is the first thing a guest touches and one of the largest single openings in your wall. A patio door is often the widest. Both are worth doing well:

• Entry doors — fiberglass and steel handle our UV and temperature swings better than most solid wood, and a properly built jamb and threshold matter as much as the slab itself.
• Patio and slider doors — the natural companion to a new deck or patio. If you are already planning a deck or patio project, replacing the door at the same time is far cheaper than doing it twice.

Installation Beats Brand Name

We will say the unglamorous thing out loud: a mid-tier window installed correctly will outperform a premium window installed badly, every single time. Flashing, sill pans, proper shimming, insulation and sealing at the rough opening — that is where leaks, drafts and rot actually come from.

That is the part we have spent four generations getting right on decks and structures, and it is exactly why we are comfortable adding windows and doors.
