My shower grout between wall and floor tile is coming loose since the chaulking in some areas has peeled away. Should I have someone come in to repair the grout (remove and replace some areas) or do it myself? Area is approx. 4 feet by 4 feet. Do I just scrape off the old, replace with new epoxy grout and rechaulk? Would someone even do a job this small? thanks in advance!

Hi, Cracks in your grout are often caused by Shrinkage , improper grout choice based on joint width and substrate flexibility movement.

Shrinkage normally occurs when too much water is added during the mixing process .Follow the manufacturer instructions carefully when preparing grout. always chose either a sanded or non sanded grout based on joint width.Sanded groups should be used when the joint width is less than 1/8.

Three of the most Common methods to prevent Cracking grout are: Do not use non Sanded grout on joints that are over 1/8thick.

Designed to fill larger joints.

Do not set tile directly over a flexible Surface like Plywood .let tends to distort over time and will cause grout to crack.

We recommended the installation of Wonder Board.

Hello! Definitely the grout needs to be fixed as soon is possible to prevent water from getting under the tiles .Yes, to make room for the new grout usually the old grout needs to be scraped out or at least partially. After grouting wait till it is dry to silicone the perimeter again. This is going to last as long as no mechanical movement happen with the floors or walls of the house. I recommend a professional to do this job , it looks small but it is a detailed one...

The grout cracked for a reason. It would be a good idea to ask a professional to have a look at it to confirm the old tile is ok to regrout or if you are just wasting your time. If the tile was installed wrong in the first place then don't waste your time and money regrouting.
