As mentioned before the price of a sliding door will depend on the size and the quality of the material used. You can buy yourself a simple piece of glass which will break easily. However, most of the glass purchased for the doors is heavy duty and hard to break. You would need a lot of force to break such glass.
Glass doors may range from $400-$700 in Ontario. This just depends on the kind of material you want. This amount will get you the regular sliding door. By natural we mean the 5 foot to the 6-foot door. This door comes with aluminum frames. You can get the extra-sized doors at 8 feet with the same construction. This door will cost a little more at $1000-$1200.
If you feel that that will just not be enough, then you can go for the 12-foot doors which will come at an even more prominent price. $1500-$3000 is the amount you will have to cough up for this size door. It will obviously have more panels than the regular sized doors due to the size.
It will cost you $400 to $1300 to have the door installed into your home. This is the price you will need to pay the installation company to send over people who need to balance the glass and place it on the frame. Installation of a glass door is not a job for one person.
