What is the Best Method for Installing a Marble Windowsills?

When it comes to installing new marble window sills, the foundation plays an important part. If the foundation of a window frame isn’t correct, then your marble window sills will not be installed properly.

To avoid wasting money on repairs from improper window sill installation, find out what the best method is for installing marble window sills.

Suggestion: Some of the suggested tools that you might find helpful are a margin trowel or a float.

Preparing the Window Sill Installation

For new builds, this will be easy as the entire structure is new and everything is being built from the ground up anyway. But for replacing and old sill with a marble window sill, first thing’s first. You’ll have to do a demolition to the existing window.  After the demo, use a chisel to get rid of any extra residue that’s hanging around after the trim removal. This will help with the base of the window frame.

Making Sure the Surface is Leveled and Smooth

This is where you need to make sure the base surface is perfectly level. Here, a leveling ruler will come in handy. This process might be a bit tedious, but it is also one of the most important steps. It is highly advised that you proceed with patience. Otherwise, rushing this process might result in a faulty installation.

If the base is not completely leveled, then the marble window sill will not be properly secured and can most likely be easily moved. This is something you don’t want. If the base surface is not leveled, you will have to use a leveling mortar to create a flat and even surface. This typically takes about a day for the mortar to dry out. Once it dries, it’s recommended to check your levels again as the settling mortar may have been affected.

Marble is a beautiful stone. It would be a shame to install it with speckles of mortar plastered on it. That is why the edges of the window sill should have a neat look. In order to accomplish this, the base surface should be straight and right angled.

Determining What You’re Working With

First you’ll have to inspect the material around the window sill, and that would be the wall. You need to determine if the walls surrounding the window frame are made of brick, concrete, or timber frames. This is crucial when preparing your window frame for marble window sill installation. If the walls are made of concrete or bricks, then you need to make sure that the base of the surface is completely flat. There can be not any slanting; otherwise the marble window sill will not lay flat. It must be level. As aforementioned, use a leveling measurement to determine if this is so.

To make sure that your marble window sill sticks to the brick or concrete, it is recommended to use a good cement-based adhesive. You can find this at your local home improvement store.

Now, if the walls are made of timber frames, this is handled a bit differently. You’ll need to use different materials. Here, you’ll need to make sure that both the marble sill and the wooden base are perfectly clean. Dust particles and other residue need to be completely removed so they won’t get locked in with the adhesive, because this will weaken the bond between the wood and marble.

Making Sure Your Window Sills are the Right Size

While most marble window sills come in standard sizes, there is a possibility that you may have to adjust the size of yours, depending on the building designer’s architectural choice. If you find that you need to adjust the length of your marble window sill, you’ll need to use a wet saw or a grinder that has a diamond blade. If you don’t the have experience of working with power tools, there are other options. You can either hire professionals to cut it for you or order pre-cut window sills. You could also order custom cut window sills from a wholesale distributor. Keep in mind that some window sill distributors, might require an additional lead time to process special orders.

Determining the Lip on Your Window Sill

Here’s where you can get creative. As marble window sills come in three standard sizes ranging from 36″, 56”, and 74″, the depth of it can be as wide as 3” – 12”. If you are going for a more decorative approach, the 12” would be more eye-catching, but for practical purposes like the windows in a shower stall might benefit from a 3” width.
