What Does Replacing Your Exterior Or Interior Window Sill Involve?

When a home or commercial building comes up for sale, the buyers notice worn, damaged sills and take them as a sign of general neglect. One detail in a home or commercial building that is often neglected is the window sill. Blinds or draperies usually cover windows, making it easy to ignore damaged window sills. Replacing worn and damaged wood sills with stylish natural stone trim will add value to any building. Using natural stone sills from Stonexchange assures the best quality and price.

Replacing a window sill is not complicated or even that difficult. It requires a few simple tools and a couple of hours of your time. This job can add many dollars to a contractor’s bottom line in commercial remodeling jobs. It can make quite a bit of money to the resale value of a home. 

Assume that you have a window structure that’s already sagging or eaten away by water. Rot is a widespread problem among those who’ve had to use wooden windowsills in the past. If this is the case, then swapping in a marble one will remove an unsightly piece of history and give the property’s future owners something to enjoy for an extended period.

Steps For Replacing And Installing A New Sill

Where do you start with your old window sill? We go into the basics. Make sure that you have tools on hand for all the steps. 

Remove The Old Window Trim

To replace a window sill:

Start with careful removal of the damaged wood windowsill. You will carefully remove the surrounding trim, if there is any, with a small pry bar.

  1. Save these pieces to reinstall later.
  2. Please make a note about where to place them.

The reason is that even if you haven’t done this in the past, you may not be able to find the way they go back on otherwise! A good rule of thumb is to arrange the trim pieces the same way they went on the wall.

Pry Out Old Nails And Screws With Your Tools

Remove any nails, screws, or other fasteners from the existing window sill. Next, lift the sill out of the window in one piece. Use this old sill as a template for the new window sill. Clean the space where the sill will go thoroughly. You will use adhesive for the new sill, requiring a clean surface. Decide which stone type and color will work best with the room decor. Look for the length, width, and depth closest to the old window sill.

  • Natural Stone window sills from us come in many lengths, including 36″, 56″ and 74″. If you have a natural stone window sill already there, then you might want to measure it first off. Then again, it’s doubtful you’d be replacing a natural stone sill because they tend to have long, useful lifespans.
  • Stone window sills come in 5/8th inch or 3/4th inch thicknesses. 3/4th inch may be in a particular order, however. Even if a special order is involved, StoneXchange can get the right size out to you.
  • Natural Stone window sills come in depths of 3″ to 12″ in one-inch intervals. There might be a trim level of variability in this, but you should be able to get a piece that fits.

If you have windows that require special sizes, you can special order custom sizes if the minimum order quantity is met. You will need to allow a ten-week lead time for special orders. If you have a ceramic or stone saw, you can cut natural stone sills to length after purchasing the closest size. You can also find a professional tile installer with the correct saw and pay them to miss the sill to measure for you. The new window sill should have 1/8″ expansion space on each side.

Forces like humidity and temperature influence even the most durable materials. Stainless steel, after all, contracts and expands the same thing is going to happen to stone as well. Even engineered stone has this issue, so a bit of space will help.

Implement New Screws, Nails, And Adhesive

Once you have the size sill you need for your window, you are ready to install it. Natural stone window sills are installed with silicone adhesive applied in quarter-size dollops every 12 inches. When you have the adhesive on the bottom side of the window sill, place it in the opening and apply enough pressure to ensure contact of the adhesive with the substrate. Reinstall the trim around the window sill and touch up nail holes, and you are done.

What Materials Are Stocked And Used For Natural Stone Window Sills
