" In my current home, I have ceramic tile. I mop weekly with Mrs. Meyers or Mr. Clean. I love it. I am reading you are supposed to clean tile with soapy water? Are streaks a problem? Can cleaning solutions be used?"

Did you mean to type "supposed to clean Concrete with soapy water?" It sounds like you already know how to clean tile.

If you like both concrete and tile, then the decision might come down to which works better for the design of your house and the cost of each.

If you like porcelain, then go with porcelain. If you want concrete then be aware that the FINISH is what takes the abuse. And a concrete finish (the sealer as you put it) comes in MANY levels of finish. From "polish" that lasts only 6 months (very cheap to purchase and apply for the concrete company = excellent price point for the homeowner) right up to a bullet proof clear epoxy that has ++ money and expertise to get into place properly.

Find out what TYPE of finish the concrete finishers are offering. Is it polish (polymere application) is it urethane (2 years worth of finish...that needs maintenance and then eventual refinishing) or is it epoxy (super tough and life-long finish with a high price tag). Find out what type of MAINTENANCE you will be required to do with that finish. Now you can compare apples to apples.

A wood-look porcelain tile will be identical to what you have now. You know what to do with it. You LOVE the tile you have and you LOVE how easy it is to take care of.

Now compare that to a low-grade "polymere" polish on concrete. There are temporary 'sealers' that are more like polish or wax. They last about 6-10 months. At that time, you (the homeowner) will be REQUIRED to reapply the finish. Yep. You need to get a buffing machine and learn how to use it. The good news is you can often reapply to the high-traffic areas (the areas that look dull, lifeless, and that are staining horribly). You will do this every 6-10 months for 2-4 years. At that time you will notice that you have finish 'build up' at the edges of your floor....kinda like a waxy build up (which is exactly what it is). Sigh. That's when you need to STRIP the concrete of all those layers of 'finish/polish'. You will chemically and mechanically strip the floors. Then you start the process all over again - Wax on; wax off grasshopper.

That is the "lower priced" concrete finish. The high-end epoxy finish is a much different animal. It will cost roughly the same price (after all the grinding and microtopping and staining and epoxy + labour) as a laid porcelain tile. The epoxy finishes require very little maintenance...in fact it will be something close to the cleaning requirements of your current tile floors.

That's why I would have a STRONG discussion with the people who offered the concrete quote. I have a sneaking suspicion that the sealant is not the "tough stuff". You are not comparing "toughest to toughest". You are comparing expensive tile with cheap(er) concrete. They are two different animals.
