MI 1650 double-hung replacement windows are MI's vinyl double-hung built as a pocket insert: it is made to the size of your existing frame, so the old jambs and interior trim stay and both new sashes tilt in. JMB Builders measures each opening, orders the 1650 through ABC Supply and installs it across the Twin Cities metro. Priced per window. Send photos and we reply within one business day, or book a free in-home estimate.
- Priced per window, 1650 double-hung included
- Made to the size of your existing frame
- Both sashes tilt in for cleaning
The 1650 is the double-hung most people mean when they say MI replacement window. It is a vinyl pocket window: no nailing fin, a frame sized to the inside of your existing jambs, and a sloped sill adapter that sits on your old sill. The old window's sashes, stops and weights come out; the jambs, casing and stool stay. Both new sashes tilt in so the outside glass is cleaned from inside.
White is the standard color. Other exterior colors and interior finishes depend on the plant the window ships from, so we confirm the list for your order before the quote is final. Grilles go between the glass, flat or sculptured, in the common patterns. Glass is dual-pane Low-E with argon, with a triple-pane option on the double-hung if you want it on the north or west side. Tempered and obscure glass are available where a bathroom or a stair landing calls for them.
Every 1650 is built to the size we send. We measure width and height in three places and take the smallest, check the sill for slope and rot, and write the size on the quote. The order goes through ABC Supply, our supplier, and we install it: old sashes out, pocket cleaned and sealed, the new unit set, shimmed, foamed and trimmed. We are the installer; options such as MI, Silver Line and ProVia are all ordered the same way.

How it is priced: per window
Quoted in writing from your photos, with a reply within one business day. What moves the number:
- Window size and the number of openings on the order
- White vinyl vs. another exterior color or interior finish
- Dual-pane Low-E argon vs. the triple-pane option
- Grilles between the glass and screen type
- Condition of the old frame and sill: a soft sill is repaired before the insert goes in
- Second-story windows that need a ladder or lift inside and out
- Interior stops only vs. new casing or a new stool
Send one photo of each window from inside with the sash open, and one of the sill. If the old frame is out of square or rotted, we tell you before the order whether a full-frame window is the better fit.
How long it takes
Lead time depends on the order and is written on the quote. Once the windows are here, 1650 inserts usually install at several per day, each opening closed the same day.

Situations and options
1650 in your old wood frames
The common case. The old sashes come out, the pocket is cleaned, and the 1650 slides in. Interior casing and stool stay. New stops cover the joint and the outside gets sealant at the blind stop or new capping over the old brickmould.
1650 over an existing vinyl or aluminum window
An older vinyl or aluminum replacement can come out entirely and the 1650 goes into the frame it left. We check that the opening is square and that the sill under the old unit is dry first.
Triple-pane on the cold side
MI offers triple-pane on the 1650. Many owners order it on bedrooms and the north and west walls and keep dual-pane elsewhere. Both can go on the same order in the same color.
MI 1650 Double-Hung Replacement Windows: questions, answered
Is the MI 1650 an insert or a full-frame window?
The 1650 is MI's replacement double-hung, built as a pocket insert with no nailing fin. It is sized to the inside of your existing frame and sits on a sill adapter. When a frame is rotted or badly out of square, we quote a full-frame MI window with a fin instead, and we tell you which at the measure.
What colors does the MI 1650 come in?
White is standard. Other exterior colors and interior finishes depend on which MI plant builds the order, so we confirm the choices for your order with ABC Supply before the quote is final. If you want a dark exterior or a woodgrain interior, we can price another line, options such as ProVia Endure, next to it.
Can the MI 1650 be ordered with grilles?
Yes. Grilles go between the glass panes, flat or sculptured, in patterns such as colonial, prairie and top-sash only. Because they are between the glass there is nothing to clean around. The pattern is written on each line of the quote so the windows match.
Does the MI 1650 come in triple-pane?
MI offers a triple-pane glass option on the 1650 double-hung. It makes the window heavier and the sash a little thicker, but the frame size is the same, so dual-pane and triple-pane units can go on one order and look alike from outside.
Will the 1650 fit my old window frames?
It is built to the size we measure, so it fits any square, sound frame. We measure width and height in three places and order to the smallest. If a frame is more than a little out of square, the gap at one corner shows and we recommend a full-frame window for that opening.
Who orders and installs the MI 1650?
We do both. The 1650 is ordered through ABC Supply, our supplier, to the sizes from our measure, and our crew installs it. If you already bought MI windows yourself, we install those too, priced as labor only.
