Subcontractor used wrong grout - best fix?

Hey Guys and Gals -

My wife and I are buying a new house (new construction). The subcontractor used the wrong grout in three areas: (1) Master Bathroom (2) Around the Fireplace (3) in the powder room (1/2 bath). He used the correct grout around the kitchen backsplash.

The grout used is a light gray. The grout he was supposed to use was a dark gray. The tiles are ceramic 12x12s. I have pictures I could email, but I don't have a website for storage yet.

I'm sure the subcontractor would like to use the quickest method of replacing the grout. I think he plans to use some knife to scrape out just a little of the grout and then apply to correct grout over the remaining wrong grout. Is this a standard practice? What are the consequences of such shortcuts?

What are the different methods of replacing grouts? What are the pros and cons of each?

Obviously we want the best quality job, but the subcontractor wants the fastest/cheapest.

Thanks for the help,

They have grout stains, as long as it has not been sealed yet.

Agreed, use a colorant, or remove at least 2/3rds of the grout that is there now and regrout, but this could damage or scratch tile when removing, I have used the colorants and they work fine, they will also seal it all in one step, and yes, like said above, it has to be used over unsealed grout.

Thanks guys.

So I don't have to worry about the grout color fading in 2, 3, 10 years?

Do I need to seal the tile once a year or every 2 years or anything?

If the tile is a glazed porcelain or ceramic, it never needs sealing. The grout colorant, if a good one is used, should stand up to many years of wear.
