The oak trim stays, the old casements go. You want a crank-out with real wood inside that matches it.
Reply within one business day. Or call / text 763-250-3621.
Andersen 400 Series casement replacement puts in Andersen's wood casement: a pine interior to stain or paint, a low-upkeep exterior in seven colors, a folding crank, and Low-E4 glass with SmartSun or HeatLock options. It is the casement for a house with stained trim that wants wood inside and no painting outside. JMB Builders measures, orders through ABC Supply and installs across the Twin Cities. Send photos and we reply within one business day, or book a free in-home estimate.
- Priced per window, 400 Series casement included
- Pine interior, seven exterior colors
- Full frame or insert, decided at the measure
The 400 Series casement is a wood window. Inside, the frame and sash are pine, left unfinished for your stain or paint, or factory finished in white and a few other colors. Outside, Andersen's cladding comes in White, Sandtone, Canvas, Terratone, Forest Green, Dark Bronze and Black. The sash swings out on hinges and pulls tight when the folding crank is turned home. A screen sits inside the sash.
Casements are the window of the Twin Cities house built from the 1970s on, often in pairs or flanking a picture unit, and often with stained oak trim. The 400 Series casement matches that trim in a way a vinyl window never quite does. Grilles can be full divided light, simulated divided light, Finelight between the glass, or removable interior grilles. Glass is Low-E4 with argon, with SmartSun for sun and HeatLock as a room-side upgrade; some sizes can be ordered triple-pane where Andersen offers it.
Most 400 casements go in full frame, since the old casement frames in a 1970s or 1980s house are usually not worth keeping. We measure each opening, check egress in bedrooms, order through ABC Supply, our supplier, and install. We are the installer. Options such as ProVia Aeris and the Andersen 100 Series casement are measured and ordered the same way if you want a comparison on the quote.

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 single vs. pair vs. casement-and-picture set
- Full frame vs. insert
- Exterior color and interior finish
- Grille style: full divided light costs more than between-the-glass
- Glass option, and triple-pane where offered
- Rot at the sill or framing once the old casement is out
- Staining or painting the interior, quoted as a separate line
Send a photo of your interior trim. If the casing is stained oak or pine, say whether you want the new window stained to match or the casing replaced.
How long it takes
Lead time depends on the order and is written on the quote. Full-frame casements install at a few per day; a casement-and-picture set is usually a day.

Situations and options
Casements to match oak trim
Unfinished pine inside, stained to match the oak casing, or the casing replaced in oak as a separate line. The crank and hinges in a finish that suits the room.
Casement and picture set
A fixed 400 Series picture unit with a casement on each side, mulled at the factory or joined on site. The usual replacement for a 1970s living-room front.
400 casements in black
Black outside, with a black or white interior. The cladding carries the color, and the exterior trim is matched. One order keeps the shade the same on every window.
Andersen 400 Series Casement Replacement: questions, answered
Is the Andersen 400 Series casement a wood window?
Yes. The frame and sash are pine inside, left unfinished for stain or paint or factory finished, with Andersen's low-upkeep cladding outside in seven colors. It opens on a folding crank with a screen inside the sash.
Can the 400 Series casement match my stained oak trim?
Closely. Order the pine interior unfinished and stain it to the trim, or have the casing replaced in oak at the same time. Pine and oak take stain differently, so we show you a sample before the whole house is finished. Staining is a separate line on the quote.
Should 400 Series casements go in full frame or as inserts?
Usually full frame. The casement frames in a 1970s or 1980s house are often rotted at the sill or too narrow to insert into without losing glass. Full frame means the old frame comes out, a sill pan goes down and the new unit is flashed to the sheathing. We decide per opening at the measure.
What colors does the Andersen 400 Series casement come in?
White, Sandtone, Canvas, Terratone, Forest Green, Dark Bronze and Black outside. Inside is unfinished pine or a factory finish such as white, with black available on some units. Hardware comes in several finishes.
Can the Andersen 400 casement be triple-pane?
Andersen offers triple-pane on some 400 Series windows in some markets. Whether it can be ordered for your casements is confirmed with ABC Supply before the quote is final. Low-E4 with HeatLock is the usual dual-pane choice for a cold wall.
Who orders and installs the Andersen 400 casement?
We do. Each opening is measured in person, the casements are ordered through ABC Supply to those sizes and hinge sides, and our crew installs them. If you already bought Andersen casements, we install those labor only.
