Is this standard protocol for installation of new windows?

Question

I've just had some windows replaced in my house, soon to have all replaced. I was curious though when I saw what they did when the bathroom window wasn't a perfect fit. Below are a couple of images of how the window was put in place. I'm not a carpenter or anything like that, but I do have my doubts that this will last several years without causing implications due to weathering and temperature changes. What do you guys think? Is there anyone out there that does this for a living with some input?

Answer 1

I don't see anything wrong  so far.  Those are shims designed to let the window sit on them, to level the window during installation. They should insulate around the edges and then cover the "gaps" with trim.

Replacement windows are not installed the same as new windows.  With the spray foam insulators available your windows should be weather tight and last for may years to come.   What is actually holding your window in, are the metal brackets on the sides of the window.  Most replacement windows just have 4 screws that go through the side of the window into the jam.  I like the brackets.

Answer 2

Looks like the rough opening wasn't quite the right size. Usually the rough opening is just 1/2" larger on the sides,top,bottom than the window unit.

Other than that, not a bad installation.

They are going to need a large apron under the window to cover the large gap, I hope the top is closer than the bottom is.

Answer 3

Probably should have added another stack of shims in the midlde to prevent the sill from rolling.

I would have added at least another 1x under the unit

Also, foam is`nt typically advisable for use on vinyl units. Check with the manufacturer, use of it may void you warranty.

Answer 4

I am a carpenter.  That's how you level a window.  You use shims on both sides (and the middle if there's a mullion like you have). They used masonry clips on the sides as well which will add to the strength of the installation.  Once they insulate and trim around it, that window will last years.  Hope this helps.
