In the above sections, we shared many tips to prevent water damage to stone door sills. However, most customers still wonder if there is any stone material that is not prone to water damage. Here are some options that are resistant to water damage:

Granite

It is a non-porous and dense stone with high moisture resistance. Moreover, it is a low-maintenance material with higher durability. As a result, it is an ideal choice for door sills.

Marble

It has a lower density than granite. However, it is still moisture-resistant when sealed or maintained properly. When using marble, you need to clean it regularly. In other words, it requires maintenance to prevent water damage.

Quartzite

You must note the fact that:

 

“The higher the density of a stone, the lesser the chance of water damage.”

 

Therefore, you should choose a natural stone with high density. Quartzite also has a higher density and is non-porous, making it ideal for door sills.

Travertine

Travertine is also a porous rock. If we do not maintain it properly, there is a higher chance of water damage. Travertine is also prone to mold and mildew.

Limestone

Limestone is a soft and porous rock. Therefore, it also comes with low resistance to mold and mildew. When using limestone for door sills, you need proper maintenance and sealing.
