Centennial became a city in 2001, but the houses are much older than that. Most of this area was built out between the early 1970s and the late 1990s, which puts a very large share of Centennial's windows squarely in the failure window right now.
We're independent. No manufacturer sets our quotas, so we can tell you what your house actually needs, including when the answer is a repair.
Early 1970s. The oldest of the built-out neighborhoods, including the areas near Southglenn and along the older Arapahoe Road corridor. First-generation double-pane units here are now around fifty years old, and essentially all of them are past seal life. If you're seeing fog between the panes on most of the house, that's why, and it isn't a defect — it's age.
Mid 1970s through the 1980s. The largest share of Centennial's housing. Two-story homes with high window counts, which is the specific situation where whole-home quotes get large fast. This is also the stock where first-generation double-pane is failing in bulk rather than one unit at a time.
1990s. The eastern and southeastern build-out. Builder-grade vinyl on homes now twenty-five to thirty-five years old. Some are fine. Many are arriving at the end of seal life in a second wave, and homeowners are surprised because the windows aren't original to a 1970s house — they're original to a 1990s one.
2000s and newer. Mostly too new for replacement, occasionally in scope for noise or isolated failures on hard-exposed elevations.
Our numbers, from our own jobs:
Centennial runs high on window count. The two-story stock built here through the seventies and eighties frequently carries twenty-five to thirty-five openings, and that's exactly where independence does real work — a thirty-window house quoted on a premium line lands in a very different place than the same house on a value line, and we can show you both instead of pushing you toward financing on the only line we're allowed to sell.
On a house with thirty openings, replacing everything at once is one option, not the only one.
Phasing works well here. Do the west and south elevations first — those take the hardest sun load and fail first — and the north elevation in a later phase. You get the comfort improvement where it actually matters and you spread the cost.
Most companies won't propose this, because the incentive runs the other way. We'll tell you which windows are genuinely worst, and that assessment is free whether or not you hire us.
Centennial's newer subdivisions tend toward large west-facing glass, and the Colorado afternoon load on those elevations is brutal.
Solar heat gain coefficient should vary by wall orientation — low on the west, a judgment call on the south, close to irrelevant on the north where U-factor is the number that matters. Almost every quote specifies one glass package for the whole house because it's easier to order. It costs no more in product to do it right.

We repair windows. Most companies in this market don't.
On Centennial's 1970s and 1980s stock the answer is often mixed, and on a thirty-window house the difference between "replace everything" and "replace the twenty that are failing" is real money.
Centennial requires permits for most window replacement work, and definitely for full-frame replacement, any change in opening size, and egress work. We pull them where they're required.

Window count is the deciding factor here more than anything else. On a high-count house the per-window price difference between lines compounds into a large number, which is exactly why seeing two options side by side matters.
Three financing paths, including a Colorado on-bill program we're an authorized contractor for. Worth knowing there's a program cap per meter, which matters on larger projects — we'll tell you where you land.
Entry, patio, and storm doors, installed by the same crew to the same standard. Patio sliders on this housing stock are frequently the same age as the windows and failing the same way.
We can source dozens of manufacturers. These are the five we know cold.

Not necessarily all at once. Phasing by elevation is a legitimate strategy on a high-count house and we'll help you sequence it.
Probably approaching it. Builder-grade vinyl from the nineties is at or near the end of its seal life now.
Afternoon solar load, and frequently a glass package specified identically for the whole house. Orientation should change the spec.
Retrofit keeps the existing frame and is faster and cheaper. Full frame is the right call when the frame itself is failing. Close to a two-times cost difference.
Yes. Entry, patio, and storm doors.
