How much to fix mould on bathroom tiling?

We've got mould growing in the grout between tiles in the shower enclosure. Some of it looks deep-set. Is this a job for a tiler to re-grout, or does the tile need to come off?

"I would grind out affected areas and re grout or another quicker way is to lightly sand grout when dry to remove layer of mould"

"Hi Minesh. The mould is probably due to poor air circulation in the enclosure. You can remove the grout and regrout but this may not solve the issue. To really get the issue resolved you would need a tiler to come round and investigate. The best scenario would be for a re tile and then use epoxy grout."

"The putty must be taken out and given with anti-mold putty, and the second option washed well with chlorine, and then with special anti-mold solution, and the third option remove the tiles and put another one"

"Generally the mould can be irradiated by spraying with Dettol ‘ mould & mildew’ it comes in a green spray….. spray it on leave for 5mins and then wash off …. Some wiping may be required … repeat if necessary ."

"If it's deep it will need regrouting. If you catch it early I would use HG mould remover. Spray on. Leave around half hour and wash off. I think you can get it at larger Tesco's."
