[MassHistPres] windows

[Dennis De Witt]

Replacement typically means the cost of a new sash.  You can bet that the manufacturer will charge you more for the replacement sash than the original cost for that sash as part of a new window because you've go nowhere else to go.

Failures can start at 15 years and few warrantees are more than 20 years and are limited in various ways -- like roof and tire warrantees.  In my experience 10 year warranteed water heaters fail like clockwork after about 7 years.  My plumber confirms that.  The replacement one is never warrenteed.  

90% of the installed organically sealed IG is less than 25 years old.  For budgetary purposes, I'd assume a 30 year life for good units, 15 years for cheap ones.

Shockingly here is something picked up at random from a local maker of replacement IG units in Maine.

"Typical life expectancy for an insulated unit is between five and ten year depending greatly on the window design."

Even I don't find that reasonable but that may be all you can expect with the unit not being factory installed in the sash.
