Worried about bay window supports

We had bay windows installed in our 1968 bungalow. There have been a number of issues with contractor and we are now concerned that the bay windows might not be supported properly.

Everything is now drywalled over. There are concrete supports that are shimmed with pieces of metal.

It seems that the window frame is what's supporting the window, since the concrete supports were not added until months after the windows were installed.

Just wondering if there is a way to tell if they are supported correctly. Where would we look for signs of stress. It's been about 4 months now...just wondering when we can sleep with assurance that they will not start to sag.

Hi Brian

Depending upon the type of bay window ie a retrofit window, they are typically supported by a cable and turnbuckle system at the top of the window as well as screws through the side jambs.

Hi Brian !

you said you have new bays installed what you did not say is what type of outside wall you have under the bay.

if you have bricks or stones that will support the stress then the bay could be put on beems from inde to out and held with screws to the frames.

If you have sopter material ouside like wood or siding or so then you need to have a "skirt".

a skirt is a lower support that is build like a box under the bay usualy with 2 x 4 and closed with siding.

the skirt can come with an angle so its connected to the far out of the bay and astrait line to a lower point on the wall .or

second way skirt cane be done is going from the outside point direct down and closed back in at the bottom. and again closed with siding so it looks as a piece of the new bay or bow. sorry i can not come to see it but i am in toronto ontario.
