Year: 2018

Mostly because they were existing, our master bath will have two full size windows. We’ll probably put plantation shutters or something on them for privacy, but they should bring in a lot of light. Replacing these went very similarly to the previous windows, with the exception that I came up with a better way of doing the exterior rigid foam that I wish I’d done all along. Since we’re putting 2″ of foam on the outside of the house, in two 1″ layers, I’ve been cutting a total of 8 rectangles to put around the windows. With these last two windows, I realized I could cut out the four pieces for the first layer while getting the entire outside layer in one piece. Not only does this reduce seams, tape, and look cleaner, it helps hold everything together better.

Removing Siding

The back window was also an opportunity to finally get the rest of the peeling siding off the house and get it covered in house wrap. Another thing I did differently with this window (though I did it with the attic window as well) was I put the house wrap on first, before I built the jam extensions. Again, that worked better, and I wish I’d done that from the outset. The house wrap probably would have looked better.

Another technique I continued with was putting the temporary tabs on the jam extension to hold the window in place, but still give me room to pull it a bit out of the wall so that I could attach the brackets. If I had all of the windows to do over again, it would be considerably easier, and a better job. That said, it would still be a complete pain, given all the reframing involved.

Really high up

See how much better it looks than the one on the first floor? That’s the first window we did. Oh well, that’s how it goes.

I haven’t posted in forever, so let me start getting things caught up, starting with the wide window that will go over the bath tub in the main bathroom. It’s a 64″ x 16″ picture window situated above head height so it will have the necessary privacy while still bringing in natural light. The existing window was a square of glass block with a louvered glass vent in the center. That was put in place of an original window that was a portrait shape but smaller than the other windows in the house, so this is the third shape/style of window that’s going into this location.

Window removed

As with all of the other windows, removing the existing window took about three minutes with a crowbar. The only difference is that this time I also needed to remove some plywood that had been used to fill the space of the original window. I used the laser level to cast the same top height as the other windows, then measured up for the header and down for the sill. I had to cut out a few studs for this window, given how much wider it is than its predecessors. First I framed in the new header and jack studs, added plywood sheathing to fill in the top and bottom where the old window was, then I used the reciprocating saw to cut back the sheathing in the resultant opening from the inside.

The next step, which proved the most time-consuming part of the process, was removing all of the siding from this section. I had originally assumed this would be fairly easy, given it’s a fairly small window, but there was the added challenge of it being on the side of the house (on the second floor), with very little room to have a ladder at a safe angle. When I previously removed the bump-out, I put up house wrap up to cover the sheathing until we are ready to put up new siding. Since that was only a few feet from the edge of the window, it made sense to remove all the siding between the window and the section already covered in house wrap. I had to move the ladder around a lot to get all of the siding off, chucking the pieces into the hole and making a big messy pile inside.

Eventually I got it cleared down to the boards, got the nails pried out or banged back in, and got the house wrap over the whole area. Unrolling a section of house wrap while up on a ladder, where the house wrap actually has to go behind the ladder, and getting it stapled up evenly, is a bit tricky. Out of maybe a twenty times I’ve put sections of house wrap on this house, I think it’s been windy nineteen of them.

Only then did I realize I’d made a mistake. I’d measured exactly where the bottom sill board should go, then cut back the studs to that height and made the opening accordingly. The problem is, that line was actually supposed to the top of the sill, not the bottom. As a result, I had to remove the sill, re-cut the studs an inch-and-a-half shorter, put the sill back in, then re-cut back the sheathing. Fortunately I didn’t get even further along before realizing what I’d done.

Window installed

Once that was done, the rest of the window went down the same way as the previous ones. I put in the plywood jamb extensions, installed the two inches of rigid poly-iso foam to the outside, taped the drain pan and sides to the foam, then added the temporary wooden brackets to allow the window to be put in from the inside and protrude on the outside an inch or so, which gives me the room I need to clip on the window installation brackets from the outside. Finally, I screwed all the brackets in, securing the window, and taped the edges of the window to the foam. I’ll come back around and put spray foam around all the windows from the inside at the same time, since the cans (or at least the straws) are pretty much one-shot.

From the outside

No rake, old boards under roof deck, window installed temporarily

With my last update, I had gotten as far as one side of the “rake” on the front gable, the frame under the edge of the roof that sticks out from the front of the house. Because I have 10′ boards, the one side wasn’t the whole length of the roof line, since the whole thing is close to 15′. Because of this, I hadn’t gotten the attic window installed, since it needs to have the exterior rigid foam around it first, and I needed the rake to be able to measure and cut the foam properly.

Ladder bracing

Crazy ladder, rake installation

For the second stage of the process I needed to handle the ladder, since the bay is under the one side of the roof, and we’ve recently put a peaked roof on it. It probably would have been smarter to do the rake before the bay roof, but that didn’t happen. Oh well; I never pretended my planning was perfect. I rigged up the ladder at a shallow angle so that it matched the roof line of the bay, screwing boards both behind the edges, over the top of the feet, and as bracing on the bay roof itself so it couldn’t slide off. Finally, I stuck a board under the ladder to account for the top ladder section being a few inches up from the bottom.

I pre-assembled the rakes inside. With that done I cut back the original boards that run perpendicular to the rafters. These needed to be cut back flush to the front wall so that I could fit the rakes tight against the house. I mostly did this with a reciprocating saw, but in a couple of spots I used the oscillating tool. I attached some scrap wood to each rake as a hanger, so that I could get it into position and screw it in without having to hold it up at the same time, especially because they’re heavy, I was standing on a ladder, and I only have two arms.

Both rakes and attic window done

I measured and cut the angled pieces for the ends out of 2×8, since my intention was for the rake to end at the eave with a point with no corner structure. Dean pointed out after the fact that I needed to account for the rigid foam that will go on the sides of the house, which I didn’t do. I’m wondering, since I need to extend the eave structure out two inches as well, if I can’t just transition that. We’ll see; worst case I redo the ends. With the rakes done I cut the foam for the gable peak and around the attic window. Then normal window installation commenced with flashing tape, drain pan, and a ton of frustration getting the installation brackets onto the window, which is also normal.

My next project was the front window of the second story bay. I’d saved it for last since that’s how we’d been getting onto the ceiling of the porch. I yanked out the giant existing window, re-framed, re-sheathed, house wrapped, took a break from window to remove much of the porch ceiling decking and railing we’d put up for the other projects. Bringing 4×8 sheets of plywood in through the window opening is much easier than lowering it down a ladder.

As with the attic, normal window installation took place, with one exception: when it came time to install the window, I installed more scrap wood on the outside of the opening to allow the window to slide beyond the edge of the opening but not fall out. This allowed me to attach the brackets without so much difficulty. It wasn’t crucial to the front window, where I can stand on the porch roof right in front of it, but this technique will help me on the remaining windows, particularly along the side of the house where there isn’t much room to work and I’ll be up a ladder. This way I can put the window in from the inside, then attach the brackets from the outside.

I’ll take down the rest of the railings and ceiling decking soon, when I go to tackle the porch roof itself. For now, I have all the materials I need to install windows, so I’m going to work on that. I’ll need some more lumber for the porch roof, even though I already bought everything a while back. That’s kind of how it goes when you cannibalize your own lumber.
