Yes, we understand your frustration. Grout lines are the single most frutating part of the cleaning process around the house. Regardless of how hard you try to clean them (even using harsh and toxic chemicals) they just don't end up looking clean.
This is because due to normal structural shiftting, grout lines over time start to crack and little pieces start to come off. Therefore holes start to appear and to the naked eye it would seem as dirt but in reality they are holes that don't relfect light consistency and it gives the apperance of dirt all over the place.
This is why poeple love our Restoration Service. This service includes the detailed and independent treatment for each and every grout line, filling in the holes and cracks and sealing it with a Colour Sealer that best high lights the tiles and gives an over all Brand New Look to your floors!
