One Second-Story Window
The one bad window is the one you cannot reach: over the garage roof, above the porch, or twenty feet up the back wall.

To replace one upstairs window, JMB Builders sizes the access to the one opening: an extension ladder, roof brackets on a porch or garage roof below it, or setting the window from inside when the style allows. The old window comes out, the new one is set, flashed and trimmed. One second-story window is a welcome job across the Twin Cities metro, priced per window, window included.

- One upstairs window is a welcome job
- Priced per window, window included
- Access by ladder, roof brackets or from inside

A second-story window is the same window as one downstairs with one extra line: getting to it. On a whole-house job the ladders and brackets are already on site. For one upstairs window, access is the main thing that sets the price beyond the window itself, so we look at the outside wall in your photos first and plan how the one opening will be reached.
Most upstairs windows are reached with an extension ladder and a standoff that holds it off the siding. A window above a porch or garage roof is worked from roof brackets and planks on that roof. Some windows, especially inserts, can be set from inside the room with the exterior finished from a ladder afterward. A lift is the last choice and only when the wall or the ground calls for it.
The window itself is in stock when a common size in white vinyl fits the opening, or custom ordered when it has to match a color or grille pattern or is an odd size, with the lead time written on the quote. An upstairs bedroom window still has to meet egress when it is replaced, so the opening size is checked at the measure. Trim inside and out is matched and primed; painting is quoted as a separate line.

How it is priced: per window
Quoted in writing from your photos, with a reply within one business day. What moves the number:
- Access: ladder from the ground, roof brackets on a lower roof, set from inside, or a lift
- What is under the window: lawn, a deck, a steep grade or a walkout drop
- Size and style of the window, and in-stock white vs. a custom ordered color or match
- Insert into a sound frame vs. full frame when the sill is soft
- Exterior finish on the upper wall: capping, trim or siding patched
- Interior trim kept, matched or replaced
The wide shot of the outside wall is what lets us quote the access. Include the ground and anything under the window.
How long it takes
Most single upstairs windows take half a day to a day on site, including setting up and taking down the access. An in-stock window is picked up for the install; a custom ordered one has its lead time on the quote.

Situations and options
Ladder from the ground
An extension ladder with a standoff against the wall. The usual way to reach one upstairs window over lawn or driveway, with the window set and trimmed from the ladder.
Roof brackets on a lower roof
For a window above a porch, garage or bump-out roof. Brackets and a plank sit on that roof so the window can be set and flashed without a lift.
Set from inside
An insert window that fits into the old frame can be set from the room. The exterior capping and sealant are finished from a ladder afterward.
One Second-Story Window: questions, answered
Can you replace just one upstairs window?
Yes. One second-story window is a welcome job for JMB Builders. We plan the access for that one opening, replace the window, flash and trim it, and leave the rest of the house alone. Send photos and we reply within one business day, or book a free in-home estimate.
Does one second-story window cost more than one window on the first floor?
Usually somewhat more, because reaching it takes a ladder with a standoff, roof brackets or a lift, and setting that up is part of the day. The window itself and the install are priced the same. The quote shows the access as part of the per-window line so you can see it.
Do you need a lift to replace one window on the second floor?
Rarely. Most upstairs windows are reached with an extension ladder or from roof brackets on a lower roof. A lift is used when the wall is unusually tall, the ground drops away under the window, or there is nowhere safe to set a ladder. If a lift is needed, it is a line on the quote.
Can one upstairs window be replaced from inside the house?
Sometimes. An insert that fits inside the sound old frame can be set from the room, and the exterior capping and sealant finished from a ladder. A full-frame replacement is worked from outside. We tell you which at the measure.
Does an upstairs bedroom window have to meet egress when just one is replaced?
Yes, the replacement bedroom window still has to provide an opening large enough to get out through. We check the opening size at the measure and order a style that meets it, such as a casement in a narrow opening where a slider would not.
Is the upstairs window in stock or custom ordered?
Either. A common size in white vinyl is often in stock at our supplier and picked up for the install. A matched color, grille pattern or odd size is custom ordered to your opening with the lead time written on the quote.
