Fixing a crumbling window sill is a relatively easy task that can be done by yourself, and can save you money in the long run. The first step is to determine the cause of the crumbling window sill. Is it a result of old age or decay? If it is decaying, then you may need to replace the sill entirely.

If it is due to age, then you may be able to fix it by filling in any cracks and replacing the brick or stone around the sill. If your window sill is crumbling, there are a few things you can do to fix it. First, you can try to patch it with a temporary solution.

How Do You Install A Marble Window Sill?

Window sills can become crumbling over time, causing the window to become unstable and difficult to open. If the sill is crumbling, it can lead to water damage as well as structural issues with the window. Luckily, there are a few steps that can be taken to fix a crumbling window sill.

  1. Place the marble sill temporarily on the window ledge.

If the sill’s edges rub on the sides of the window opening and prevent the sill from fully fitting into place, mark the sides of the opening where the sill’s surface meets the sides and set the sill aside.

  1. Using a utility knife, score each side of the opening from back to front at the marks. Remove a 1/8-inch deep portion below the scored line from front to back on each side of the opening with a wood chisel and hammer. Using a shop vacuum or the vacuum hose on a household vacuum, remove any debris from the window ledge.
  2. Place the marble sill completely on the ledge. Make a mark along the underside of the sill where it meets the face of the wall below.
  3. Flip the marble sill over onto a flat surface, underside up. Insert a silicone adhesive tube into a caulking gun. With the knife, cut a 1/4-inch opening in the tip of the tube.
  4. From end to end, apply 1/4-inch thick circular portions of adhesive every 6 inches between the back edge of the sill and the reference mark. The servings should be about the size of a quarter.
  5. Flip the marble sill over and place it on the window ledge. Apply pressure to the surface of the adhesive.
