Dirty, stained grout can make an otherwise clean floor look old and worn.

You'll be so confident in your home after this.

Understanding the cleaning process
After inspecting the grout quality, tile and condition, the tile and grout will be cleaned deeply. We do this all by hand, as steam cleaners risk further damage to tile and often trap more liquid within the grout. Following the cleaning of the tile and grout, we will give expert recommendations for the sealing of the grout. This will depend on your goals and plans for your home, the current color of your grout, and condition of the floors. If recommending sealing, we will guide you on colors that will enhance the beauty of your floors.
Will the grout need to be sealed?
Grout is a porous material and if left unsealed, it will quickly discolor. Whatever is spilled onto the grout, whatever dirt, bacteria or mop water that lands on the floor is now there within your grout. Once the discoloration of grout begins, there is nearly nothing that can remove such stains. Often people are left with the option to completely remove the grout and replace it. If you choose to replace your grout: don't forget to seal it so this doesn't happen again. But STL Grout Works offers a much more affordable and easier option than the replacement of dirty grout!
STL Grout Works proprietary grout sealer penetrates into the grout lines and dries as hard as the tile forming a permanent, protective barrier against stains, discoloration and bacteria. This Color-Sealing process is what you need to be investing in! Color Sealing your grout can completely transform the look of your tile floor.


Can I use a clear sealer on my grout?
There are many clear grout sealers on the market today. The main concern with a clear sealer is how often they need to be re-applied. Most clear sealers will require that the floor be stripped and re-sealed every few years. The clear sealer will cause your grout to begin to yellow. This goes against the very purpose you initially used the sealer!
The other disadvantage to clear sealers is that unless the grout is brand new, you are sealing in stains and discoloration. Because the stains and discoloration have penetrated deep into the grout lines they are unable to be removed by steam or pressure cleaning machines. These machines will be able to remove some of the surface dirt but not the deep stains and grout discoloration.
Why Hire a Professional Grout Cleaner?
Grout lines can be difficult and time-consuming to clean by hand. Professional cleaning provides a deeper, more consistent clean while saving homeowners hours of scrubbing.
STL Grout Works specializes in tile and grout care and can also identify and offer solutions for areas where cleaning alone may not fully address deep discoloration.
