Hi everyone, i noticed my bathroom tile grout is cracking, planned to have it replaced.

My question is
1) Usually find any contractor can do?
2) What's the cost like labour + material? i have few bathrooms need to fix.

I don't want diy although many youtube videos provide guidance. If it's too expensive then i might diy

got photo to show?

Just buy pye grout, mix with water then fill in the gaps.

Then wait for about 40 min, use wet cloth to wipe away excess grout.

Easy. If want all the grout to be of same color there are those paint pen type with fungicidal formula.

but need to remove the old grout before applying new one right?

Not really. From my experience the pye grout will stick to it quite well.

Oh yea. Better still, can pour in pye krack seal to all the grout places and let the liquid seep in.

Cracking grouts are a sign of old building and likely the waterproof layer also likely to have cracks. The krack seal will flow in and form a waterproof layer. Do this before applying grout as pye grout is waterproof.

My bathroom tile grout is cracking when I washed the floor.
Any views on how to fix the problem? contractors are quoting me RM1.3k-1.5k each toilet for re-grounting using epoxy material.

Will that really solve the problem? Any other cheaper solution? Please~
