Wendy A - Novato, CAJune 03, 2026

Mark and Noah are amazing! They listened to our concerns and observations. Technician Noah is extremely detail-oriented. He updated us at each decision point to verify we're on the same page. The bathroom grout in the shower and floor look brand new, not 30 years old. Also as the hazy marble countertop we just accepted as the best it can be, is now actually shiny. I highly recommend this company.

Ulises was on time thorough in his explanations hard working and I'd have no problem recommending him to others. His workmanship was above par by the time he finished the shower and kitchen sink they looked brand new. I'd have no problem hiring him again.

Working with Sir Grout and their front person Mark along with the staff has been a real joyful experience. They're so professional when they come in analyze the work that needs to be done and they work with you on the price what I got was absolutely perfect work I had grout and things that were impossible to get the calcium out and they got it out of my shower.

They did a beautiful job sealing my deck so I don't have any leaks into my roof. Everything they've done here has been perfect. No other gentleman that comes and does a lot of the work was fabulous. I recommend I'm 100% and I'm very particular.

The tile floors in our kitchen and family room are 20 years old, and the grout was dirty looking and in some places had broken. We had tried other methods to clean the grout with little success until Sir Grout came to our house. Ulises was the tech who did the work. He was amazing and the results exceeded our expectations.

The grout and floors look new again. We are so pleased and will be recommending Sir Grout to our friends. Mark, the owner initially came to our and gave us free estimate and explained the process. Try Sir Grout, you won't be disappointed.

Ulises did a fabulous job and was very professional. Our laundry room tile was dirty and had a weird pet smell from the previous owner. It looks fantastic now.
