what to use for exterior window trim.

I am installing andersen 400 series windows in my home this spring and I have to cut a 2 inch channel around the old andersen windows so I can tear the old windows out and replace the new ones with the storm flaps. the old siding butts right up to the window. I will need to use some form of brick mould or trim on the 2 inch gap. what is the best material to use for longevity and low maintainence. I was wondering about vinyl brick mould? Is some type of wood a better option? what is your opinion if you were going to do this yourself? thanks

What type siding?
Picture of what you have now would be great.
PVC brick molding is all I ever use any more.
Always best to predrill the holes for the nails, make sure to use a nail set and use galv. finish nails.

No special blade needed.
Cuts the same as wood, just do it a little slower so it does not melt.

You're going to have a hard time properly flashing the windows with only 2" to work with, especially at the head. You may manage on the sides and sill, but may need to remove a row of siding at the head to have room to install the z-flashing. Get the flashing right, and don't skimp, it's the most important part of the install, IMO.

I was looking for flashing the other day and could not find it. the most I could find was colored coil stock. I have used that on doors before, but it would be nice to have preformed flashing. where do you find it and what is the name they use for it. never heard it called z flashing before.

Menards... same aisle as gutters and downspouts. Lowe's / Home Depot have it too, and any other lumber yard worth it's salt.

I figured out how to cut the siding with a real thin cutting wheel. I was also trying to figure out what type of brick mould to use. with the j-channel attached or just pvc or vinyl. what do you use? I was also wondering if you left a 1/4 inch gap around the windows and used backer rod? does the pvc or vinyl need the extra 1/4 inch for expansion and contraction or just butt it up to the window. I normally use silicone caulk for this type of work. is there something better? is one type of silicone better than another? you were right about the 2 inch being not quite enough cutout around the window. probably need 2 1/4 inch.
