Many buyers are under the assumption that since it’s marble and has proven to last for decades, even centuries, that no maintenance is required.

The truth is, if your buyers expect their window sills to look the same way they did the day they bought the dwelling from you, then it’s your responsibility as the builder to educate them on how to properly maintain it. Buyers will appreciate this and are more likely to recommend your business to other developers.

Marble is available in a wide variety finishes.

  • Honed: For a matte finish, the honed type is what you’re looking for. The surface here is buffed just enough to take that high gloss away leaving just enough shine to reveal it’s smooth, yet dull appearance. This kind of window sill finishing is typical for neutral designs where builders are trying to appeal to a wider buying market.
  • Polished: This is the kind that most people are familiar with. Its shiny surface is synonymous with luxury and wealth. As a result, most high-end department stores and boutiques prefer this kind of window sill to present expensive products. Its luminous surface is also great for reflecting light in tight spaces—perfect for showcasing jewelry and other precious mementos.
  • Sandblasted: This kind of finish takes the Bush Hammered look to another level. To achieve this look, the marble sills are subjected to a high-pressure jet of sand that scratches the surface enough to give a refined, yet busy appearance that appears almost neutral.
  • Bush Hammered: For a more rustic looking theme, the bush hammered finish presents a striking appearance with a textured, leather-like look that will pair well with Black Granite sills. It would make perfect framing for a nightclub or exclusive beauty salon. It’s also a good option for rural or country-themed builds.

Quality Products Make Good Business

When building your commercial dwelling, why not include a tiny engraving in your marble window sill? It’s all about making your mark. Most marble sill patterns are quite busy and such a mark wouldn’t make to big of a difference. A nice gesture like this can go a long way! Think of all of the historical buildings that stand today with their name and date on it. Perhaps it could be on the edge of the sill. It doesn’t have to be on the surface. Just don’t let your customers mark up their new window sills educate them on how to properly care for it.

It’s a beautiful product and deserves to be kept up!
