MI 3500 casement replacement windows means a crank-out ordered to match a house of MI 3500 windows: the 3500 itself is MI's single-hung, so the casement comes from MI's casement line in the same color and grille pattern, with a nailing fin or finless as an insert. JMB Builders measures, orders through ABC Supply and installs across the Twin Cities metro. Send photos and we reply within one business day, or book a free in-home estimate.
- Priced per window, casement included
- Matched to MI 3500 series windows on the house
- Fin frame or insert, decided at the measure
The MI 3500 is a new-construction single-hung: a vinyl window with a nailing fin that builders put in by the hundreds in Twin Cities houses from the late 1990s on. It is not a casement. When a 3500 house needs a crank-out, over a sink, in a bedroom that needs egress a single-hung cannot give, or where a stuck sash has worn out its welcome, we order MI's casement in the same color and grille pattern so it sits beside the 3500s without looking added on.
A casement opens like a door on a crank and seals against the frame when it closes, which is why owners pick it for the kitchen and the windy side of the house. MI's casement comes in white as standard, with the same between-the-glass grille profiles as the rest of its vinyl line, dual-pane Low-E argon glass and a full screen on the inside. It is built to the size we measure, in a fin frame for an open wall or finless to go into the existing frame.
The order goes through ABC Supply, our supplier, and we install it: old single-hung out, sill pan and flashing when the fin version goes in, foam, sealant and trim inside and out. We are the installer. Options such as MI, Silver Line and ProVia casements are all ordered the same way, so if the 3500 color is no longer made we show you the closest match before anything is ordered.

What you supply
- Photos of the opening inside and out, and of a 3500 window next to it for color and grille matching
- Hinge side: left or right as seen from inside, or a pair that opens from the middle
- Whether the wall will be open (siding job or addition) or the casement goes into the existing frame
- Paint or stain color for new trim: Painting is quoted as a separate line — or leave it primed and caulked and paint it yourself.
What JMB supplies
- In-person measure, with a check of the 3500 frame color and grille pattern beside the opening
- The MI casement, ordered through ABC Supply to your size, hinge side and color
- Removal of the old window and haul-away
- Sill pan, flashing tape and fin fastening on an open wall; sill adapter and sealant on an insert
- Low-expansion foam, backer rod and sealant inside and out
- Interior stops or casing and exterior capping or J-channel work to match the 3500s
- Crank, hinges, lock and screen adjusted so the sash closes tight
- Photos of the finished window 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:
- Casement size and whether it is a single sash or a pair
- Fin frame on an open wall vs. finless insert into the existing frame
- Color beyond standard white, if the house has colored 3500s
- Grilles between the glass and glass upgrades
- Egress requirement in a bedroom that may change the size
- Siding cut back and patched around a fin install
- Rot at the sill or framing once the old window is out
A casement over a sink or in a bedroom is usually one or two openings on a quote. If other 3500s are failing, adding them to the same order shares the measure and the trip.
How long it takes
Lead time depends on the order and is written on the quote. One or two casements install in a day; a fin install with siding work takes longer.

Situations and options
Casement over the kitchen sink
The most common request. A single-hung over a sink means leaning across the counter to lift it. A casement cranks open from the handle at the bottom and the screen is inside, out of the weather.
Casement pair for a bedroom egress
A casement opens its full width, so a pair can meet the egress size a single-hung of the same frame cannot. We check the clear opening the code calls for before the order goes in.
Casement in a 3500 house getting new siding
With the siding off, the casement goes in with a nailing fin, sill pan and flashing, the same way the 3500s were set. Any other windows being replaced go on the same order.
MI 3500 Casement Replacement Windows: questions, answered
Does MI make a 3500 casement?
The MI 3500 is a single-hung window. When a house of 3500 windows needs a casement, we order MI's casement from its vinyl line in the same color and grille pattern. It is a different model, but it comes from the same maker and matches the frame finish.
Will a casement look right next to MI 3500 single-hungs?
From outside, yes, in the same color and grille pattern. A casement has one sash where a single-hung has two, so the glass is one piece with no meeting rail. Most owners like that; we point it out before ordering.
Should I get a left-hinge or right-hinge casement?
Hinge it so the open sash does not block a walkway or a deck door, and so the crank is on the side you can reach. Over a sink, hinge it on the side away from the faucet. Looking from inside, left or right is written on the quote.
Can a casement be put in without taking off the siding?
Yes, as a finless insert into the existing frame, if that frame is square and sound. The fin version needs the siding cut back so the fin can be fastened and flashed, and it is the better install when the siding is coming off anyway.
Can you match the color of my MI 3500 windows?
If your 3500s are white, yes. If they are a color, we confirm with ABC Supply that the casement is offered in it. If the shade is no longer made, we show you the nearest current color and let you decide before the order.
Who supplies and installs the MI casement?
We do both. The casement is ordered through ABC Supply to the size, hinge side and color from our measure, and our crew installs it. If you already have an MI casement in the garage, we install it labor only.
