Job types, priced apart in both frames
| Frame | Job-type line, as published | 2026 band |
|---|---|---|
| Frame A | garden window installation, per window | $1,200-$3,650 |
| Frame A | new or larger opening, added | $2,000-$3,000 |
| Frame B | garden window, installed | $1,000-$4,000 |
| Frame B | new installation, against replacement | up to 50% more |
Every figure here is a published line inside its own frame and job type, never folded into the other. One frame prices the job-type gap as a dollar adder; the other prices it as a relation on a single band. The project whole prices on the garden window hub; the size and material layer on the size and material guide.
Replacement in place, as reported
| Replacement line | Frame | 2026 band |
|---|---|---|
| Installation band, average $2,500 | Frame A | $1,200-$3,650 |
| Installed band, replacements below new | Frame B | $1,000-$4,000 |
A replacement sets a new garden unit into an opening that already holds one, and both frames read that job as the lower-priced job type. Frame B prints the relation in words: replacements cost less than new installations on that frame, because the opening is already in place. Frame A prints its installation band with the new-opening adder apart from it, so the band itself is the replacement reading.
First-time installation, as reported
| New-installation line | Frame | 2026 band |
|---|---|---|
| New installation, against replacement | Frame B | up to 50% more |
| Creating a new opening, prep line | Frame A | about 50% more |
A first-time installation puts a garden window where a flat window, or no window, sat before. Frame B prints new installations at up to 50% more than replacements. Frame A prints a prep line of about 50% more for creating a new opening. The relations agree in size and stay apart in frame.
A new or larger opening, as reported
| Opening line | Frame | 2026 band |
|---|---|---|
| New or larger opening, added to the project | Frame A | $2,000-$3,000 |
| Enlarging an existing window | Frame A | $2,000-$3,000 |
| Separate opening band | Frame B | no separate band |
The opening is the one job-type line Frame A prices in dollars of its own: a new or larger opening adds $2,000 to $3,000 to the project, and enlarging an existing window prints at the same $2,000 to $3,000 on that frame. Frame B prints no separate opening band on the lines carried here; its opening reading lives inside the up-to-50%-more relation between its two job types. That absence prints as published.
Reading the job-type gap, by frame
The question a buyer brings is whether the existing-opening job prices apart from the new-opening job. Frame A answers in dollars: one installation band, one opening adder. Frame B answers in relation: one installed band, replacements below new installations, new work up to 50% more. The two voices name the same gap and price it apart, with nothing averaged between them.
- Job type named beside every band: replacement, first-time, or new opening
- Opening adders read as Frame A lines only, wherever they appear
- Replacement readings never read as new-installation readings
- Installed totals read whole, on their own frame
Frequently asked questions
Does replacing a garden window cost less than a new installation, as published?
Yes, on Frame B's printed relation: replacements cost less than new installations on that frame, and new installations print at up to 50% more. Frame A prints its band at $1,200 to $3,650 per window with the opening adder apart.
What does a new or larger opening add, as published?
Frame A prints a new or larger opening as an adder of $2,000 to $3,000, and enlarging an existing window at the same $2,000 to $3,000. Frame B prints no separate opening band; its opening reading sits inside its up-to-50%-more relation.
What does a replacement garden window print at, as published?
Frame A prints the installation band a replacement is checked against at $1,200 to $3,650 per window, average $2,500. Frame B prints one installed band of $1,000 to $4,000, with replacements priced below new installations inside it.
Why do the frames price the job-type gap differently?
Frame A prices the gap in dollars, as an opening adder on its installation band. Frame B prices the same gap as a relation on one installed band. Each reading stays on its own frame's lines, never blended.
Can the replacement and new-installation readings be averaged into one job band?
No. The two job types print apart inside each frame -- an adder apart from a band in Frame A, a relation apart inside a band in Frame B -- and the frames themselves are never blended either.
