You want to make sure that your top crown moulding piece is level. Now it's time to head on over to the window and make sure the top moulding piece is the correct measurement, and start nailing it to the wall. That way you can shave off just hairs of measurements (if you need to.) Remember, your moulding will be cut at an angle, so its always good to measure a little more than you need to. Next, it is time to measure for the top crown moulding. We set some weights in the window sill to help the glue set in well to the sill. We were able to get a pretty good fit, the small gaps between the wall and sill will be caulked. Now it is time to fit the new sill into the window frame.
Pictured below: For our downstairs windows we laid down a cement base to raise up the window sill, and level it. We used Liquid Nails which is an adhesive, and this will give it the secure fit that we need. Since the sill is hollow, we are not able to use a nail gun to set the sill how we like. Here we measured out the custom fit for the window sill. Next, we measured the window sill depth and how far we wanted the sill to come out on both sides of the window. Since we had no use for the old marble sills we ended up donating all the sills to Habitat for Humanity Restore. So the next step is to measure the depth of the sill so that you can determine what size your new sill needs to be. The new window sills are going to consist of wood. Then we used the rubber mallet to slowly pry the marble sill up. First, we used a scraper to remove the caulk around the window sill. (Sorry the picture is so bright- you can still see by the looks of the window that it is nothing special)įirst, you will need to remove the window ledge. Here is the before picture of the window, you can see the marble window sill that will be removed in this photo. Primer (only if you moulding is not primed, ours was).Liquid Nails (for gluing down the wood window sill).
My husband prefers to use the nail gun, because he says my taste will probably change, meaning he will be doing new window trim eventually.
Of course, if you tackle a few windows at once you can cut some costs and buy more wood in bulk and save a little. We priced it out and it can cost anywhere from $40-75 per window, depending on the dimensions and or type of moulding you choose. It is amazing that by adding some custom casing to any window can make a world of difference. For the last 2 years we have been slowly working on giving our windows a beautiful new makeover.
