Question DetailsAsked on 3/16/2014

how much does it cost to replace trapezoid windows

they are 3ft wide and 30 inches at higest point and 20 inches at lowest point. Of course the bottom of window is flat. I wasn't sure if I could have the double pane glass replaced or have to get whole new window because the seal's are broken

You can probably be the glass replaced if you want to go that route but you will have a more comprehensive warranty with a full replacement.

They aren't that big but the shape windows are more expensive.

Depending on applications and options, somewhere between $700 - $1,200 per unit is probably median numbers.

For that size, I am sure the numbers WoWHomeSolutions gave you are for a "prime" window - totally new frame and glazing unit. To replace just the glazing unit, unless a very unusual design, that can be done by a glass replacement company. They will come and measure carefully, order the unit made, then come back a few days to a couple of weeks later to install the new sealed glass unit, which is an exterior glazing frame (usually aluminum) containing the 2 or 3 layers of glass and/or interior foil or plastic glazing. Exterior frame and trim remains essentially untouched and is NOT removed.

Odd shape will add just a bit to your cost - not at all an unusual situation, and odd shaped and rounded top and such glass can all be replaced without replacing the external frame in almost all brands of windows. Because they will charge for 3ft x 30 inches, discarding the 10" by 3' scrap from each pane, cost will be a bit more per square foot but not terrible - depending on type of glass, special ultraviolet or heat reflecting surfaces or whatever, might run from $250-500 range for double pane, assuming not above second story. If very high or very hard to get at, or low to floor or next to front door so safety glass is required, then at high end of range.

I was quoting completely new units (full frames)
