Thomas C - Seattle, WAApril 25, 2026

This was a worst-case scenario. The installation used very expensive white marble from Ann Sacks with white epoxy grout from a company called Laticrete. Unfortunately, I learned the hard way that their white grout can have a tendency to turn yellow over time. I also later learned that many professional tile installers refuse to use Laticrete white epoxy grout because of this issue.

Because epoxy grout cures as hard as cement, the problem was extremely difficult to fix.
To make matters worse, the contractor who originally installed it refused to fix the problem.
I spoke with several professionals and was told that the only options were either to remove and replace all of the tile or use a grinder to remove the yellowed grout, which could chip and damage the marble.

After doing extensive research, including using ChatGPT, Sir Grout was recommended as the best company for the job. There was only one person at Sir Grout who had both the experience to remove Laticrete epoxy grout and the willingness to take on such a challenging project.

His name is David, and he is awesome. Not a single tile was damaged during the process, and he used a different manufacturer's white grout that will not turn yellow. Sir Grout also provides a one-year written guarantee on the grout work.

In addition, the white tile itself had begun to show yellow staining, and Sir Grout was able to remove almost all of those stains as well.
Needless to say, I will be using Sir Grout enthusiastically for any and all future projects involving tile or grout.

Our bathroom looks amazing, definitely refreshed and looking much newer. The technician spent extra time working on the tougher areas, much of this by hand. Happy with the result.

Look. I'm a real estate agent. One of the things I need to do is have a strong list of trusted vendors to do all sorts of different jobs.

Grout cleaning and fixing is a service a lot of people don't realize exits and/or that they need! People generally don't even realize their grout has changed color over the years. Sir Grout will also refinish natural stone surfaces like marble. Also making it look brand new again!!

These guys always do an insanely good job! Every time I've used them the work has been flawless.

And yesterday I was chatting with an employee and he said something incredibly important. He said his boss is one of the nicest people ever and the best boss he's ever had. That means a lot! That is the kind of culture that makes for quality work.

I can't recommend Sir Grout enough. Awesome service. Awesome people.

Jeremy was so easy to work with. He patiently answered my questions and concerns and explained the solutions. The work turned out beautifully. One piece especially. I was sure the hard water stains and scrub marks on the granite would never come out. It looks brand sparkling new!! Thank you.
