The outside trim on my patio door (doublewide) has water damage on the bottom of all trim pieces. I would like to replace it all but not sure how to go about it. I find the brick mold pieces in Lowe's but do not see any of the pieces under the brick mold or the trim that runs between the doors Do I have to make all of this from scratch? Does any place have a "trim kit" that has all the pieces? Any help would be appreciated. Thanks

You Want Find Any Kit With All The Pieces For These Doors. I Assume You Talking About The Jamb That Is Rotten Behind The Brick Molding, On This You'll Have To Either Chisel Out The Rotten And Replace It With Wood Or Use A What I Call Rock Hard Putty And Still Remove The Rotten And Patch With The Puddy, You Can Get It At Lowe's Also. It's a 2 Part Mix, You'll Have About 5minutes To Work With It Till It Gets Hard, Then You Sand, Sand , Sand, So Get It As Smooth As You Can, And It May Take A Few Coats.
As For The Other Pieces I Usually Use Clear Pine And Prime It Really Well And Top Coat With A Exterior Laytex.
Some Else You May Want To Do Is Use Is Pvc Brick Mold, It Will Be Just One Less Thing You'll Have To Replace Again, It Cost I Think A little Less The Wood And It Looks The Same,

Since you have a doublewide, check with a trailor supply place or at a new trailor sales lot. Ihave gotten repair materials for trailors this way several times.Trailor materials are different from reg. building material.
