Silver Line 70 Series casement replacement is for the builder-grade vinyl casements in Twin Cities houses of the 1990s and 2000s: the cranks strip, the seals fog and Silver Line no longer sells the 70 Series by that name. The replacement is a current casement sized to the same opening, options such as Silver Line V3. JMB Builders measures, orders through ABC Supply and installs. Send photos and we reply within one business day, or book a free in-home estimate.
- Priced per window, new casement included
- 70 Series is a builder line no longer sold by that name
- Current casement sized to the same opening
Series 70 was Silver Line's builder-grade new-construction designation, and a lot of it went into Twin Cities subdivisions built from the mid-1990s on, casements included. Twenty-plus years later the pattern is familiar: fogged glass from failed seals, crank operators that spin without moving the sash, hinge arms that let the sash sag, and weatherstrip that has gone flat. Parts for a discontinued builder line are hit and miss, and a casement with two of those problems is a replacement, not a repair.
Silver Line regrouped its windows into the V1 and V3 series, and the 70 Series name is gone. A casement today comes from the V3 series, white or with a Dark Bronze or Black exterior, Low-E argon glass, grilles between the glass, with a full screen inside. It goes in with a nailing flange when the siding is open, which is how the originals were set, or as a finless unit into the existing frame when the siding stays.
We measure each opening, check the frame for rot where the old sill met the siding, order through ABC Supply, our supplier, and install. We are the installer. If you would rather not stay with Silver Line, options such as MI, Andersen 100 Series and ProVia casements are measured and ordered the same way, and we can put two on one quote.

Three photos and a sentence is enough: a reply within one business day, or ask for a free in-home estimate. Or text the photos to 763-250-3621.
What you supply
- Photos of each casement from inside with the sash open, and one of the outside wall
- A photo of the label on the frame or glass spacer if you can find it
- Hinge side for each casement, or keep what is there
- Exterior color and grille pattern, and whether the siding is staying
- Paint 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 of every opening, with a check for rot where the old flange met the siding
- The new casement, ordered through ABC Supply to your sizes and hinge sides
- A line-item quote by opening, with a second line such as MI or Andersen 100 beside it if you ask
- Removal of the old casements and haul-away
- Flange install with sill pan and flashing tape in an open wall, or finless install with sealant
- Low-expansion foam, backer rod and sealant inside and out
- Interior stops or casing and exterior trim or J-channel to suit the siding
- Crank, hinges, lock and screen adjusted on every sash, 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:
- How many casements are being replaced, and whether the rest of the house comes along
- Finless insert into the existing frame vs. flange install with the siding cut back
- White vs. a dark exterior, grilles and screen type
- Single casements vs. pairs and casement-plus-picture sets
- Rot at the sill or sheathing found when the old flange comes off
- Second-story openings that need a lift or scaffold
- Interior trim: keep, new stops or new casing
If only some casements have failed, we can replace those now and write the color and grille on the quote so the rest match later. Replacing the whole set at once shares the measure and trip.
How long it takes
Lead time depends on the order and is written on the quote. Casement inserts install at several per day; flange installs with siding work take longer.

Situations and options
Replace the failed casements only
The fogged or stripped units come out and current casements go in, matched in white and grille pattern to the rest. The remaining 70 Series windows stay until they fail, with the order written down so the next batch matches.
Whole house of 70 Series windows
When most of the house is the same builder line and the same age, one order for all of it keeps every frame the same shade of white and the grilles the same pattern. Casements, double-hungs and picture units from one series.
Casements with the siding off
If the house is getting new siding, the casements go in with a flange, sill pan and flashing tape to the sheathing, the way the originals were set but with flashing the builder may have skipped.
Silver Line 70 Series Casement Replacement: questions, answered
What is a Silver Line 70 Series window?
Series 70 was the builder-grade new-construction designation Silver Line used for the vinyl windows sold in volume to builders, including casements, in the 1990s and 2000s. The name is no longer used; Silver Line's current windows are the V1 and V3 series.
Can I still get parts for Silver Line 70 Series casements?
Some operators and hinges are generic and can be matched; sashes and glass units are harder. When a casement has fogged glass plus a worn crank or sagging hinge, a new window is usually the better spend. We say which at the measure.
What replaces a Silver Line 70 Series casement?
A current casement sized to the same opening. Staying with Silver Line means the V3 casement, in white or a dark exterior, with Low-E argon glass. Options such as MI, Andersen 100 Series and ProVia casements fit the same opening, and we can price two lines side by side.
Why do the casements fog?
The seal between the two panes failed and moist air got in. On builder-grade windows the seals often go within fifteen to twenty-five years. Once a unit fogs it does not clear, and on a discontinued line a new glass unit may not be worth chasing.
Does the siding have to come off to replace the casements?
No. The new casement can go in finless into the existing frame if the frame is sound. If the siding is coming off anyway, or the old frame is rotted, the flange version goes in with a sill pan and flashing tape, which is the better install.
Who supplies and installs the replacement casements?
We do. Every 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 windows, we install those labor only.
