A quote to replace 20 windows from JMB Builders is priced per window: each of the twenty listed with its style, size, insert or full frame, glass and trim, so you can see what each one costs and compare. We cover the Twin Cities metro and north to St. Cloud. Send a labeled photo of each window for a reply within one business day, or book a free in-home estimate; every opening is measured in person before ordering.
- Priced per window, all 20 listed
- Every window measured in person first

Most people searching for a 20-window price have already counted. The count matters less than what each window is. Twenty double-hungs of two sizes, set as inserts in sound frames, is one job. Twenty windows that include a bay, two tall stair units, a few casements upstairs and rot under three sills is another. Same count, very different quote.
So we price per window and list all twenty. Each line says what the window is, how it goes in, what glass it gets and what trim is done around it. The total is the sum of the lines, which means you can see why it is what it is, drop a line, or move a few windows to a second phase without re-quoting the house.
There are no dollar figures on this site. What we can tell you is what moves the number, below, and that the setup cost of one measure, one order and one set of install days is spread over twenty windows instead of three.

What you supply
- A photo of each window from inside, labeled by room, and a few from outside
- Rough window sizes if you have them (not required; we measure)
- Brand, color and glass choices, or a request to quote two options
- Your paint or stain color — Painting is quoted as a separate line — or leave it primed and caulked and paint it yourself.
What JMB supplies
- A per-window quote listing all 15 to 25 openings
- One in-person measure of every window before ordering
- All windows on one order so color and glass match
- Removal, sill pan, flashing, foam and sealant at each opening
- Interior trim and exterior capping or trim as quoted
- Haul-away of the old windows and photos in your job folder
How it is priced: per window
Quoted in writing from your photos, with a reply within one business day. What moves the number:
- The mix: how many standard double-hungs or sliders vs. casements, bays or specialty shapes
- Insert or full frame, window by window
- Brand, frame material, glass package and grilles
- Upstairs and over-roof windows that need more access
- Siding, stucco or brick around the openings
- Interior trim: new stops only, new casing, or drywall returns
- Rot or framing repair found when windows come out
Label each photo by room (Kitchen 1, Kitchen 2, Bed 3) so the first quote lines up with the measure.
How long it takes
Lead time depends on the brand and is written on the quote. Twenty inserts usually install in about a working week; full frame with exterior trim takes longer.

We walk the finished work with you. If anything is not right, we fix it before we call the job done. Then one invoice, paid by check or direct deposit — no card fees, no payment links.
Situations and options
All 20 on one order
One measure, one delivery, one set of install days. Color and glass match on every window, and the house is disrupted once.
Two quotes, two brands
The same twenty lines priced in two brands or two glass packages, side by side, so the difference is the product and not the scope.
15 now, the rest later
Each window is its own line, so you can move the five best ones to a second phase. The brand, series and color are written on the quote so they match later.
Quote to Replace 20 Windows — How 15 to 25 Windows Are Priced: questions, answered
How much does it cost to replace 20 windows?
It depends on what the twenty windows are, not just the count, and this site does not publish dollar figures. JMB Builders prices each window on its own line: style, size, insert or full frame, glass and trim. Send a labeled photo of each one and we reply within one business day, or book a free in-home estimate.
Is it cheaper per window to replace 20 at once?
Usually the per-window share of the fixed costs is lower, because one measure, one order and one set of install days cover twenty windows instead of a few. The window itself costs what it costs. The quote lists each window so you can see the difference if you phase it.
Why are two quotes for 20 windows so different?
Most of the time the scope is different: one bid is inserts with stops only, the other full frame with new trim, or the glass packages differ. Put the quotes side by side window by window. If a quote is one number for the house with no list, ask for the list.
Can you quote 20 windows from photos?
Yes, for a first number. Send one photo of each window from inside, labeled by room, and a few of the outside walls. Nothing is ordered until every window is measured in person, which is when hidden rot or odd sizes show up and the quote is firmed.
How long does it take to install 20 windows?
Twenty insert windows usually take about a working week once the windows are on site. Full frame installs with new exterior trim take longer. The window lead time depends on the brand and is written on the quote.
Should all 20 windows be the same brand?
Yes, if you want frame color and glass to match from room to room. Style can still change by room: casements where you want air, sliders where a sash cannot swing. Mixing brands on one house is where color and sightlines stop lining up.
