Start with condition
If the grout is firm, full and only stained, cleaning and recoloring are good options. If it cracks, crumbles or is missing, it should be replaced.
Press a hidden line with a screwdriver. Firm grout is a candidate for recoloring.
Cleaning first
Sometimes grout only looks bad because of soap film and soil. Deep cleaning can restore the original color and costs the least.
If it comes clean, sealing may be all you need.
Recoloring
Recoloring covers permanent stains and mismatched lines with a durable colorant and sealer. It does not repair cracks, and it works best on firm grout.
It is quick, clean and a very good value when it fits.
Regrouting
Regrouting removes the old grout and replaces it entirely. It costs more and takes longer, but it fixes cracks, softness and persistent mildew and lets you choose a new product and color.
It is the best choice when failure is widespread.
Mixed approaches
Many jobs combine methods: regrout the shower, recolor the floor, clean and seal the kitchen. Each surface gets what it needs.
A free inspection tells you what fits each room.
Think about the long run
A cheaper step now may mean another visit in a few years. A stronger fix costs more now and lasts longer. Consider how long you will stay in the home.
Epoxy grout can make sense where you want the longest life.
Clean if it is dirty, recolor if it is stained but sound and regrout if it has failed.
