is there any harm in not having my limestone floor restored right away?

Scratches begat deeper scratches. Think of a spec of dust or dirt as a ball bearing rolling under foot. When it encounters your scratch instead of rolling straight, it diverts to run down the scratch digging it deeper. Marble restoraion times and costs are largely determined by your DEPTH of damage. The deeper the scratch the more time, or number of honing steps needed to remove the scratch, and consequently the greater the expense. As with all things, a proper maintenance program can reduce your total care cost. A good stone craftsman can restore your floor, and provide you guidance on how to care for it with the right cleaners, matting strategies etc. Keeping your floor properly polished not only looks good but helps protect your floor. A quick annual polish can keep your floor looking beautiful for years to come.
