Wrapping wood trim for replacement windows
Hello, I'll be installing vinyl replacement windows this spring. I've looked at several finished jobs and would like to do it right. My windows are recessed in the brick veneer. I'm trying to figure out a way to make some kind of a "clip" to hold the aluminum in place so I don't have to use as many nails. Does anyone know of a way to fasten the aluminum in some way without nails?? or do they make any type of a thin small edge trim to insert the wrap on the outside edges by the brick? Thanks

I suppose Liquid Nails would work, but you need to be really good with a break to do interlocking seams, far to expensive from a labor viewpoint.

one way is to cut a slot along the window trim and brick with a diamond blade or a FEIN MULITMASTER TOOL, just the thickness of the blade. bend your alum so it goes behind the window parting strip and around into the slot you just made along the brick. then caulk the alum to the brick. I also do the same under the window sill. ( I bend it back under the sill about 3/4") BOB

This is great. I've never belonged to a forum before, these are good suggestions. I attached a picture of the exterior. If you could, take a look and respond. I don't think cutting a slot will work, but let me know what you think. The wood is rounded and there's old caulking between it and the brick. Thanks a lot for responding.

It would require a little more work but....

You could set the windows closer to the face of the brick. Wood jamb extensions could be built on the interior side, which is a cool architectural feature.

I really wanted to use the standard method of installing the replacement window in the 3-1/2" deep opening. I don't know if moving them out toward the brick would look right with my old home?!

yes the slot could be done but like KC states it will take time. then clean up the brick with a wire brush and install the alum capping then caulk, you will have a nice clean appearance.
when you install the alum over the sill , take a hand saw and cut along the bottom of the side casing where it rests against the sill just cut enough so that it is even with the side interior jambs then you can slide the alum. in under the casing tight against the jambs and then you can caulk the sides to the sill. bring the alum all the way up to the interior stool. this way if the window leaks the sill is covered.

OK. I can make the slot between the wood and the brick, but the gap between the two is a lot of old caulk. I could run my reciprical saw blade along the brick to "separate" the old caulk from the brick and then slide the alum edge into it, then new caulk to keep it in place. The sill will be easy, as there's no caulk at the brick edge. Am I on the right track? Thanks again.

yes! a recp. saw might make a mess of the brick. Could you chip the old caulking off with an old chisel. and then keep putting an edge on it with a belt sander to keep it sharp. BOB.

another method you can use after you remove the old caulk is to bend your aluminum trim into a Z shape with a 1/2 flare.Caulk between the wood trim and the brick and install the aluminum over the caulk joint,with the flare bend lapping onto the brick witch will protect the caulk and reduce maintenance.I'm not sure i would i would cut a saw kerf into the brick at the sill

All of the caulk around the windows is silicone and still fairly soft. I think the recip. saw blade will be OK if I use it with a bend in the blade and not let it deface the brick. The same could go for making the slot under the sill.
I'm not sure what the Z bend is? Tell me if I'm staying on course, as this is really helpful.

Correct! I must define my description. make a slot between the brick and the sill. so to slide the alum under the sill and on top of the brick. then caulk along the brick and the alum. sill. Just a slot big enough for the slide into. :thumbsup:

when you bend coil your actually making shapes as viewed from the end.
If you do 1 bend its called an L shape,2 bends going in the same direction is a U shape.2 bends going in opposite directions is a Z.You could also remove old caulk with a wire wheel chucked in your drill, wear eye protection of course

Tom Struble 02-22-2009 01:07 PM

ah yes mr bulletbob that is a nice way to do it:thumbsup:

Sparky 55 02-22-2009 01:17 PM

You guys may have answered this one, but am I correct in starting the wrap for the side jambs from the inner side of the blind stop, bringing it out and around to the brick? which will cover the blind stop? Thanks
