An Andersen Narroline sash conversion kit install is labor only: you order the conversion kit or replacement sashes from Andersen or a dealer, and the old sashes and liners come out, the new liners and tilt-wash sashes go into your existing frames, and the stops and trim are reset. JMB Builders does it across the Twin Cities. Andersen window sash replacement installer, priced per window, quoted from photos.

  • Priced per window, labor only
  • Narroline kits and Andersen replacement sashes
  • Independent installer, not an Andersen dealer

Andersen's Narroline double hungs went into a lot of Minnesota houses. The frames usually hold up; the sashes and the old jamb liners wear out, the glass fogs, and the sashes do not tilt in for cleaning. Andersen sells conversion kits for these windows: new jamb liners and new tilt-wash sashes that go into the existing frame. The frame, interior trim and exterior stay as they are.

You order the kit or the sashes from Andersen or a dealer by the window's size. We install them. The old sashes and stops come out, the old liners are removed, the new liners go in and are fastened as the kit instructions show, the sashes go in and are adjusted to tilt, lock and seal, and the stops go back. We check each frame before we start, because a rotted sill or a frame out of square will not take a kit well.

To be plain: we are an independent installer, not an Andersen dealer, and we do not speak for the factory. We install what you order, to the instructions in the box, and we will look at your order against your windows before you place it.

Andersen Narroline Sash Conversion Kit Install, Labor Only: questions, answered

Who installs Andersen Narroline sash conversion kits?

We do, labor only, across the Twin Cities. You order the kits from Andersen or a dealer; we install the liners and sashes in your existing frames and reset the stops and trim.

What is in a Narroline conversion kit?

Andersen lists new jamb liners, tilt-wash sashes, balancers, a new lock and installation instructions. That lets the sashes tilt in for cleaning while the existing Narroline frame and trim stay. Andersen notes the kit is not for combination units dated March 1994 or earlier, so we check the window before you order.

Can you replace just one Andersen window sash?

Yes. Andersen sells replacement sashes for many of its windows, ordered from the label or the frame size. We install the single sash and adjust it. If the frame is rotted, we tell you first.

Is a Narroline kit better than a new replacement window?

When the frames are sound, a kit keeps the original frame and trim and costs less work. When the sills are rotted or the frames leak around the outside, an insert or full-frame window is the better fix.

Are you an Andersen dealer?

No. We are an independent installer. You buy the kit or sashes from Andersen or a dealer; we install them to the instructions in the box. We check your order against your windows before you place it.

Do you paint the stops and trim after a sash kit install?

Painting is quoted as a separate line, or leave it and paint it yourself. Stops that break coming off are replaced to match.
