I applaud your advanced concerns on doing your exterior upgrades in a logical manor. While most people are only concerned with one or the other, not many choose to do them in a proper procedure. Your siding contractor was very proper in telling you to do your windows at the same time. As a matter of fact we're doing a window job this morning that is having the siding replaced as soon as we're done. This is by far the best way to make your home as energy efficient as possible.

Your choice of windows is really up to what you want the look to be. The windows of today have much to offer. You can have real wood interiors, fake wood interiors, vinyl or aluminum. When it comes to energy efficient windows, vinyl windows are really leading the industry. They're cheaper and more economical to the end user. If you can use a white or almond color they're the way to go. You happen to live in an area that is abundant with vinyl window manufacturers. Simonton is probably one of the better of the vinyl window manufacturers here in the Nation and they have plants in your area. I'd definitely check them out.

By replacing your windows before doing the Hardiplank, you can have your windows set properly with the moisture barrier. Make sure the siding contractor works with the window installers to have this done properly together. By removing the old window and installing the house wrap, you get the ultimate installation for your home. If they don't have the chance to work together, have the window installers pre-wrap the openings with house wrap extending out past the nail fins of each window. They can leave the tops unwrapped for the siders but the sides and bottom can be done for the siders to attach their house wrap to.

Good Luck and I hope things go well for you!!!

Wow, guy exterior man -- I'm not the original poster, but I definitely appreciate your explanation. We have a brick home, but there are two areas with cedar siding which needs to be replaced. I also want to replace the windows, but didn't know which should be done first. The only advice I've been able to get is that it doesn't matter, but I knew that it probably could make a big difference. You provided a great explanation which will help me in finding someone to do the work. I love these forums!!!
