Getting Stuck Marvin Windows to Move

 

11 September 2005

 

 

 

Some number of years ago, we renovated our current home and as part of the renovation installed Marvin, wood-frame, double paned, low E, Argon gas filled windows throughout the house. Marvin makes a nice window. 

 

After all renovations were complete to include the complete painting of all walls, ceilings, trim and all Marvin window wooden-frames, when we moved in, we found that none of the Marvin windows would slide open.  At first I thought that perhaps that the window installer (not Marvin) had somehow jammed the window into too small of an opening in the framing of the house but that really did not make sense as all windows were a custom order for our home.  Then I thought the problem was that because the windows did not have handles on the lower window (guess an option we did not know about or did not choose when ordering), which could be used to life the window with that, that was the problem, so I took the effort to find nice handles and install 2 on each and every window and still the windows, none of the windows would open.

 

Now, we do not open our windows often but after a while, it became the principle of the thing.  Windows should open and open easily and so if it was not that the windows were installed in too tight of a frame (how could all windows have been installed that way?) and it was not that the bottom window lacked handles to pull up on, then the only answer had to be that the wood frame was too tight against the vinyl track on each side of the window.

 

So, I began the process of taking each wooden-frame window out and sanding the wooden edges, which are supposed to slide against a vinyl track installed in the window frame.  But when I took the very first window out, I discovered that when the painters painted the wooden frame of the window, they were not careful about not getting paint on the raw wooden edge of the window, which slides against the vinyl frame.  No wonder the window would not slide or open.  So using a powered sander which had a triangular shaped pad and 100 grit sandpaper, I began removing all paint from the slider side of each window.  With 100 grit sandpaper, it did not take long to remove any traces of paint and then when I replaced the window into the frame it did slide now but still was not as smoothly and easily as I wanted it to be.  So if there was no paint on the window slide edge, what about track itself and sure enough, there was also paint on the vinyl track into which the wooden-frame of the window sits and slides.  Here, a sander could not be used as I did not want to ruff up the surface of the vinyl but rather used a paint scraper and got most, if not all paint off the vinyl side rails.  Now when I installed the window into the vinyl sliders and latched it into place, using my installed handles the window slid up and done easily.  Paint!  Paint on the slide side of the window and vinyl track had been the cause of the windows not opening all along!

 

Finally, as one last step, I went to a craft store and bought a box of paraffin, which comes in sticks and proceeded to wax the raw wood side of each window so that the edge was waxy.  Now when I lifted up on a window handle, the window slid open easily, just like it should.

 

So the bottom line and I suspect that it is true for all windows, is that you cannot have any paint on the slider side of the window or the frame it slides in and that waxing the slider side of the window will help make the window slide more easily.

 

Oh, as a side note, when I took out the lower window in some window frames, I discovered that the sash hardware (spring and small pulley and cord) was broken.  Sash hardware is an assist to lifting heavy windows and also to allow for the latching of a window into a position other than fully open or closed.  In my case, some of the sash pulleys had broken and in other cases, the metal clip to which all associated sash hardware is attached had broken free of the vinyl track at the top of the window.  In all I had about 7 broken window sash units and had to call Marvin to get them replaced.  Marvin was very good about replacing the sash hardware, which was not expensive, and they sent an installer to do the job.
