Recent Review: This all went very well. Beth came out within a few days after my call and gave me two estimates. The first estimate was for cleaning and sealing the tile and floor in the main bath and cleaning and sealing the tile in the 1/2 bath at a cost of $210.00. The second estimate was for cleaning, sealing and applying a colored sealant in the main bath which would have added $275.00 to the cost. I chose the less expensive one, understanding that due to the age of the tile in the main bath the grout might not come back to full white. The grout in this bathroom was badly stained. It had not been cleaned since the house was built in 1951, and because the previous occupants were heavy smokers, it was heavily stained with nicotine residue. The technician, Brian, arrived on time and went right to work. He worked diligently and completed the work to my satisfaction. Although the grout did not come back to white, it was an acceptable almond color, which was much better than the yucky brown it had been before. I am pleased with the results, and recommend this company highly. I was having an event at my house and hoped that Grout Medic could complete the work before that, which was in a pretty short time frame. Beth told me that they might not be able to do the work in that short time frame, but had a cancellation and she worked me in. Very happy with that!
