How to stop sealant bleeding under door window molding?

I have sanded and scrapped previously and sealant returns. Molding is not an "off the shelf" item.

    Hi Charlotte, what sealant did you use? If it's a latex caulk they tend not to dry, which may be what's causing your leakage.

    That is the sealant that is seeping. As the door/window warms up the sealant softens/melts and seeps out. Use a utility knife and cut the paint around the frame both inside and outside.


    Work from the inside. Close the door. Locate the screws that fasten the outer framework of the glass insert to the door. If the screws aren't exposed, use a small screwdriver to pop off the small decorative caps covering them to expose the screw-heads. Save the caps. Remove the screws using the appropriate screwdriver and save the screws. Remove the framework by hand and put it aside it for re-installation. You may need to use a putty knife to pry it off since the sealant melted.


    Have someone on the outside. Push the top of the insert outward with the flat of your hand, and ask your assistant to remove the insert from the outside of the door.


    Remove the all the sealant from the opening in the door and the face of the insert, using a plastic putty knife.


    Place the insert in the door. Set up a caulking gun with a tube of 100% silicone sealant. Cut off the tip of the tube to make a 1/8-inch opening, using the utility knife. Apply a uniform bead of sealant around the outside edges of the insert where it meets the sides, top and bottom of the opening in the door.


    Install the saved framework using the saved screws and the screwdriver. If necessary, reinsert the saved decorative caps over each screw-head.

    This is a factory-installed window. The door was manufactured cir 1997.

      Williams plan will work, but you will need to find the screws that fasten the window. They were probably plugged with a wooden or rubber cap to cover them. If you contact the manufacturer or look at a current model, you might be able to figure out where they are.

    Is this anything like what is seeping out from the window frame?

    If you use clear caulking (or caulking that is white but dries to clear) that would help as well. Then you wouldn't see any at all.

    We have the same thing happening on our sunny exposures French Doors.

    Wiliams idea above sounds like the correct approach.

  • I would keep removing it until it stops bleeding through. I would assume after you trim it off a few times it will stop bleeding (hopefully!).

    Hi, Maybe the wrong sealent was used. If a poly (Shiney finish) it will not take paint. You need to use a Decorators filler suck as Pollyfilla. Then the paint will stay where you put it.

    needs to be caulked

  • You can use a clear caulking one that dries out clear. This can help too.

    Hi Charlotte, you can try sanding then putting a coating of a caulking that will accept paint, right over the existing caulking, then you can repaint and it should stick.

    Agree make sure it is 100% silicone so it will be as water proof as possible.
