Replacement Window install

I'm thinking about tackling a window replacement project myself. I spend several years working as a frame carpenter, so I have new window install down, but never have done a replacement. Is it as simple as remove existing window, plumb, square and level the new window in the opening and install some screws and trim work? (Not that its ever that "simple")

thanks, dan

Provided your window frames are in good shape, yes it's about that simple. The most important thing is ordering the windows correctly, (1/4 smaller than the opening) so that you have room to square the window in the opening. Generally, you don't have to worry about level and plumb, provided the old opening is reasonably straight. The main thing is getting the replacement window square, and making sure that the frame is not spread or twisted in the middle.

If your current windows have a removable interior window stop, then you're home free- easiest installation in the world. If you plan on painting the exterior, your replacement windows will just push up against the blind stop, and you can paint the rest of the trim. If you prefer to wrap the openings with aluminum trim coil, I prefer to do that once the old window is removed. You can do a quality job of wrapping that way.

One of the biggest mistakes I've seen, though, is installers not thinking about flashing the windows. Wrapping windows is a great way to trap water unless the installer is careful to give attention to those details. This is especially true when several other layers of siding have been applied on top of the original sheeting & siding- it makes it very difficult to flash everything properly. If you give attention to these things when you install your windows, you'll be miles ahead of quite a few "professionals".

I agree with sleeper, replacement windows take about 30 min to pop in. Very very easy.
