Our house has stained & scored concrete floors throughout the main areas of the house. The guestrooms have carpet. The master had part carpet, part scored stained concrete. The house was built 10 years ago, and I don't think anyone has re-sealed the floors. There are stains all over the kitchen and cracks here and there. The carpet in the master was ruined by a guest-dog, so we ripped it up to see what was underneath. As you can see from the pictures, there are holes where the carpet was nailed in, and there was bare concrete underneath.
We want to pull up the carpets in the guest rooms as well. We've talked about re-surfacing/scoring where needed, the entire house. We've also toyed around with wood floors for the master. How successful are concrete re-do's? Let me know what you think!
