Buff and recoat
There is a test you can do yourself in a minute that tells you whether your floor needs sanding or just a fresh coat.

Call and describe the floor, or send the details and we will come back to you. Either way the first conversation is about working out which job you actually need.
A name, a number and a line about the room is enough. Anything else you add makes the first reply more useful.
With which of the six jobs your floor is likely to need, and what the range depends on. If what you have described sounds like a smaller job than you were expecting, we will say so.
Some things cannot be judged from a photograph. How much wood is left, whether a subfloor is sound, and what a slab reads for moisture all need somebody standing on it.
What the work is, how many days, what has to be moved beforehand, and what it costs. Nothing is booked until you have agreed to all of it.
Photographs are more useful than measurements at the start. The most helpful ones are the worst patch, a wider shot of the whole room, and anything happening at a threshold, near a radiator or under a window.
Rough dimensions are enough. Pacing a room out is fine and nobody needs it to the inch at this stage.
It also helps to know what the floor is now, if you know, and roughly how old it is. If it has been sanded before, that is worth mentioning, because it changes what is still possible.
And say what is bothering you about it. A floor somebody wants to look new again and a floor somebody wants to stop squeaking are different jobs, even when they are the same floor.
We work on floors across Staten Island, from the North Shore neighbourhoods around St. George, Stapleton, West Brighton and Port Richmond, through the Mid-Island around Todt Hill, Dongan Hills and Westerleigh, down the South Shore through New Dorp, Great Kills, Eltingville, Annadale and Tottenville.
If your street is not on that list, it does not mean anything. It is a short way of saying the whole borough.
These two pages answer the question most people are actually asking.
There is a test you can do yourself in a minute that tells you whether your floor needs sanding or just a fresh coat.
What the full job involves, and what actually moves the price.
If something is actively wrong rather than just tired, this is the page that covers it.
