install window w/ old aluminum siding

apiersma's picture

hi all:

I am ordering new construction wood windows w/ aluminum clad (old frames are rusted steel and need to go). I don't want to replace old aluminum siding for a few years.

If the new exterior clad casing extends beyond the point where the old brickmold and old siding meet, is it easy to pull off the old aluminum trim ( J channel, I think its called); then cut back the siding a 1/2 inch or so; then reinstall the old aluminum J channel?

The top of the windows are above the siding so I am not so concerned about them.

I realize that this may not make much sense, so please help me understand the transition from casing to alumunim siding.

it would be difficult to remove the old aluminum J- channel with damaging it. I would rip out the old J- channel, cut your aluminum back where  you need to, then slip in new pieces of vinyl J- channel. You can put aluminum J-channel back but you would have to make that on a brake. Vinyl J-channel you can get at home depot is like $4 for a 12 foot piece. It will look nice, I've done this a million times.........Good Luck

new clad windows and aluminum siding....sounds like 22" spinners on a Kia.

"22" spinners on a Kia"

That's so accurate ... rest assured I will replace the siding in the future. The windows alone are going to kill the budget.

And thanks Craigabooey for the good idea. Now I need to find vinyl J-channel that the wife thinks matches the windows. I assume you can't paint the vinyl J-channel?

I never heard of anyone having any luck painting vinyl J-channel, but you can get in all kinds of colors at siding yards. Good Luck!

So, do you work in the barrio or the getto where such things are more common?

 My office is in one of the Less than desireable neighborhoods in Philadelphia.  Just about once a year someone gets shot or stabbed or otherwise has a bad day on or adjacent to our property.

 The only real draw to being stationed there is that the Housing allowance is $1650 a month plus a $200 a month cost of living adjustment.

  At my last duty station it was a straight $1100 a month.

 This evenig on the way home I saw Lincoln that had been lowered so low, when they tried to pull in for gas it got hung up on the rear Bumper. It had spinners.
