RE-GROUTING ON STONE JOBS:Re-Grouting is not always necessary. An assessment by our Estimators or Technicians is a must. We will give you an honest solution. Most of the time a deep cleaning & minor re-grouting will do. Grout can never be 100% color matched but we do the absolute best to blend. If total or minor re-grouting is needed then when getting estimates make sure yours includes the proper prepping for re-grouting your job. Grout does not stick to grout so all existing grout must be removed. Also be aware that this is a very hard & dusty process & if proper technicians are not doing work then more damage than before start can happen.

If there is a lot of cracking in your existing grout you must also know that this is not normal & there may be another problem. An under lament improperly installed can cause movement. Grout is basically cement with no flex. So if Tile has been set directly to wood or Hardi Backer not screwed in properly you will get movement. So re-grouting may in actuality be a waste of money. The cracking will eventually return. The Tile needs to be redone correctly. Re-enforcement from under may be solution if reachable.
