My home is 24 yrs old and has Marvin wood casement windows. During my
annual window painting exercise, I noticed that all the west facing windows
and a few on the east side have loose joints in the lower half of the window
frames. On a few windows the pins that hold the mortise and tenon joints
together are loose and beginning to protrude above the frame. Almost all
the windows have developed horizontal cracking running with the wood grain
especially where the bottom brick mold meets the brick sill. Scraping
revealed cracks on the exterior of the wood, but nothing on the interiors as
they appear to be fine. Over the years I haven't had to do anything but
paint as they have been faithfully maintained otherwise. In addition to the
wood cracking, I now have one window where the seals have failed and the
glass is foggy so I'm beginning to think this is going to begin happening
regularly due to their age.
I know I can replace the glass in these windows, but my question is whether
24 years is about the expected life expectancy for wood casement windows?
If I need to replace them I know I can get the exact same windows from
Marvin in either wood or vinyl clad, but is the clad window worth the extra
Thanks in advance for any comments.
