Westminster is a split-level city, and that is not a figure of speech. A very large share of the housing here went up through the 1960s, 70s and 80s as the corridor between Denver and Boulder filled in, and the split-level and tri-level plans of that era came with wide aluminum-framed glass on the stair landings and living rooms. Those are the coldest surfaces in the house on a 19-degree January night.
Standley Lake and Cotton Creek are that era. Legacy Ridge and Bradburn are newer, Bradburn built as a walkable new-urbanist neighborhood. The city has also spent years turning the old Westminster Mall site into a new downtown, so the housing mix keeps shifting. What does not shift is the Front Range combination of intense sun, hard cold, and hail.
In-house background-checked crews, and tall split-level stairwell work is routine for them.
Written line-item pricing, with the large stairwell units costed separately rather than averaged in.
We file with the City of Westminster Building Division and confirm the adopted energy code edition.
Our workmanship is covered for life, and the manufacturer warranty stands behind glass and hardware.
Every style, built for Westminster's climate.
Two sashes that slide vertically, the standard bedroom replacement in these split-level plans.
Cranks outward on a side hinge and seals firmly, a solid choice on an exposed upper level.
Glides horizontally on a track, the usual swap for a wide living-room opening in a tri-level.
One large fixed pane, the best-insulated option and the right unit for a tall stairwell wall.
Multi-panel windows that project outward, adding depth to a plain 1970s brick and siding frontage.
Awnings vent from the top in a storm, and garden windows add a bright shelf above the kitchen sink.
For Westminster's cold climate we most often install vinyl or fiberglass frames with high-solar-gain Low-E 180 glass.

Westminster sits in climate zone 5B between Denver and Boulder, cold and dry with strong high-altitude sun and an active hail season. Retaining heat while capturing winter sun is the priority. This is the assembly we install on Westminster homes:
| Spec | Recommended for Westminster | Why |
|---|---|---|
| Glass coating | high-solar-gain Low-E 180 | maximum winter insulation + solar gain |
| Frame material | Vinyl or fiberglass | harsh winters near 19°F, no warping, tight seal |
| Gas fill | Argon | argon (krypton optional) for deep-winter insulation |
| U-factor target | ≤ 0.27 | exceeds the Colorado energy code requirement for zone 5B |
| SHGC target | higher = better | captures free solar heat (no code cap in cold zones) |
On a split-level the stairwell glass is where the money leaks. Those tall runs of single-glazed aluminum sit right where warm air collects, so they lose heat faster than any other opening in the house. A high-solar-gain Low-E 180 coating with a U-factor near 0.27 turns that wall from a liability into something that actually contributes on a sunny winter afternoon. Power runs about 17 cents per kilowatt-hour.
Window installation in Westminster typically runs $550 to $950 per installed window, or $11,000 to $20,000 for a full home. Split-level and tri-level homes have a quirk worth knowing: the tall stairwell openings are large units and often need scaffolding or interior staging, so they price above a standard bedroom window. Newer Legacy Ridge and Bradburn homes are simpler. With local home values near $540,000, we quote fixed and itemized.

We measure each opening on site, including the tall stairwell runs, and plan the access before quoting.
Your units are built to those exact openings with a coating chosen to capture winter sun.
Most Westminster homes install in a day, and we file with the Building Division beforehand.
We protect the floors, take the old aluminum out, and register your warranty before the crew leaves.
Westminster requires a building permit for window replacement, filed with the City of Westminster Building Division. Expect a closer look when you resize an opening, alter a bedroom window subject to egress rules, or modify a header, which on a split-level stairwell wall is a real structural question. Colorado sets no statewide residential energy code, so cities adopt their own, and Denver metro jurisdictions have generally moved to the 2021 IECC with a 0.30 maximum U-factor in zone 5. We confirm Westminster's current adopted edition when your installer pulls the permit rather than assuming it.

Yes. The City of Westminster Building Division requires a building permit for window replacement. Your installer files it, confirms the adopted energy code, and books the inspection.
For zone 5B Front Range conditions, we recommend high-solar-gain Low-E 180 glass with argon fill in vinyl or fiberglass frames at a U-factor of 0.27 or lower, so winter sun helps heat the house.
Most Westminster jobs run $550 to $950 per installed window, or $11,000 to $20,000 for a full home. Tall split-level stairwell openings are large units and price above a standard window.
Electricity runs about 17 cents per kilowatt-hour. On a typical Westminster home, efficient windows save about $568 a year on the ENERGY STAR published figure for this climate zone, or about $282 if you are replacing older double pane.
Yes, and it is usually the single highest-value opening in the house. Those runs of aluminum-framed glass sit where the warmest air in the home collects, so they lose the most heat. We assess access and whether the header carries the span before quoting the unit.
Yes. Every installer we match you with is licensed, bonded and insured in Colorado, and their work carries a lifetime workmanship warranty from your installer alongside the manufacturer's warranty on the windows. We arrange your quote and the introduction; your installation contract is with the installer who does the work.
