Fix it: Installing a replacement window

[DarkSkies]

11. After you shimmed it out, and everything is cool, complete the setting of the 4 screws.

Sometimes you will have a pretty large gap on the sides if the measurement is off, or the guy who puinched in your order made a slight mistake. You can and should use fiberglass insulation in these gaps, and should caulk over the end gaps. Caulk is expensive. Sometimes to save on caulk with a huge gap, I'll stuff newspapers in there (sides only). As long as you know moisture won't leak into there (like a shower window), it should be ok and help you get the job done cheaper and quicker.

I use an average of one tube of caulk or less per window, inside, outside, and all the molding gaps. Before I learned this trick I would use 2-3 tubes. That $$ adds up quick when you do 25 windows at a time.


Pellas have a side adjustment screw. Make sure this snugs up to the sides before you put everythiing together, and there is no binding as the window goes up and down.
