Marietta Wood Flooring has handled wood floor refinishing in Marietta, GA for more than 20 years, serving surrounding cities including Fair Oaks, Holly Springs, Smyrna, Kennesaw and Vinings. We sand worn hardwood down to clean wood, correct the color, and lay down a new finish that is matched to the way your household actually uses the floor.
Most refinishing calls here start with the same floor: red oak installed in a Cobb County subdivision, finished honey or golden, and worn gray in the hallway and kitchen after years of traffic. Some want the color changed, some want the orange tone gone, and some only need the shine brought back. Each of those is a different job, and the right one is decided by what the boards can take.
We measure before we promise. Every refinishing estimate starts with the wood left above the tongue, a moisture reading and a check for old wax or shellac, so the quote reflects a floor that can actually be refinished rather than one we discover is too thin halfway through.
Signs Your Floor Needs a Full Refinish
Gray Traffic Lanes and Bare Wood
When foot traffic wears through the finish, the exposed oak turns gray and starts absorbing dirt and water. Those traffic lanes usually run from the front door to the kitchen and down the main hallway. Once the gray reaches bare wood, no recoat will hide it; the only fix is sanding the whole room back to fresh grain so the color and the new finish match wall to wall.
Leaving bare lanes too long invites water stains and splitting at the board edges, which turns a refinish into a repair job. Catching it while the damage is still in the top layer keeps the cost down.
Deep Scratches, Dents and Sun Fade
Scratches from pets and furniture that go into the wood itself, dents from dropped pans, and sun fade under a south-facing window all sit below the finish. A full sand removes the damaged surface evenly, so the room reads as one color again rather than a patchwork of old and new wood.
Dents in soft species like heart pine may not sand out completely without taking too much wood. We tell you which marks will disappear and which will soften, before we start rather than after.
When a Screen and Recoat Is Enough
If the wear is still in the finish and the wood underneath has not grayed, a screen and recoat may be all you need. It abrades the existing top coat and adds a fresh one without sanding into the wood, for a fraction of the cost and time. We recommend it whenever it will do the job, because every full sanding removes wood that a floor never gets back.
What We Check Before Any Sanding
Wood Left Above the Tongue
A solid hardwood board can only be sanded until the groove is exposed. Builder oak from the 1980s and 1990s in Cobb County has often been refinished once already, and some previous crews took off more than they needed. We look at the board edge at a floor register or threshold to see how much wood remains, then decide whether a full sand, a lighter sand or a recoat is the safe choice.
When the wood is too thin to sand again, we say so plainly. Sanding through into the tongue exposes nail heads and splits along the edges, and at that point the boards need replacing rather than refinishing.
Moisture Readings on Cupped Boards
Cupped boards with raised edges tell us moisture is coming from below, usually a damp crawlspace during a humid summer. A moisture meter shows whether the boards are still wet. If they are, sanding flat now would leave them crowned once they dry, so we find the source, wait for the readings to fall, and only then sand.
Old Wax, Shellac and Build Year
Older homes near Marietta Square may have paste wax or shellac on the floor under a later coat. Modern polyurethane will not bond to either, so we test for them and strip them fully during sanding. We also check the build year, because the EPA RRP Rule reaches homes built before 1978 and changes how we contain dust on those jobs.
A floor with old wax on it often shows the problem before any test: a finish that peels in patches, a surface that stays slightly sticky, or a new coat that fisheyes into small circles. Any of those on a previous refinish tells us the prep was skipped.
Sanding, Stain and Finish Choices
Grit Sequence and Dustless Sanding
We sand with a drum sander on the field of the floor and an edger along the walls, stepping through a grit sequence from coarse to fine so the scratches from each pass are removed by the next. An orbital sander then blends the edges and the field. Our sanders connect to vacuums for dustless sanding, which keeps most of the dust out of the rest of the house.
Skipping a grit to save time leaves swirl marks and chatter that only show once the stain goes on. We check the floor under a raking light between passes, because a flaw found after staining means sanding the whole room again.
Stain Samples and Water Popping
Stain color looks different on every floor, so we lay stain samples directly on your sanded boards before choosing. For darker colors on oak, water popping raises the grain slightly so it takes stain more evenly and more deeply. You approve the sample in your own light, not from a showroom chip.
Maple and pine absorb stain unevenly and can go blotchy. On those floors we often recommend a lighter tone or a clear finish, because the most even color comes from choosing the right stain rather than forcing a dark one.
Waterborne, Oil-Modified or Hardwax Oil
Waterborne polyurethane dries clear and fast, and keeps light oak and white oak from ambering. Oil-modified polyurethane warms the color and builds a thicker coat per pass, which is why older floors often look orange. Hardwax oil soaks into the wood for a low-sheen look that is easy to spot-repair but needs regular upkeep. Clear finishes fall under the varnish category in 40 CFR 59 Subpart D, and we choose products by that category.
Sheen level matters as much as the finish type. Satin and matte hide scratches and dust far better than gloss, which is why most families choose them for busy rooms.
Refinishing the Species Found Around Marietta
Builder-Grade Red Oak
Red oak is the most common floor we refinish, installed in thousands of subdivision homes across Marietta and east Cobb. It takes stain predictably and sands cleanly, which makes it the best candidate for a color change. Orange oak is usually red oak under an oil finish that has ambered; sanding and finishing with a waterborne product brings it back toward natural.
Red oak has open grain with a pink undertone, which shows through gray and white stains more than owners expect. We test those colors on your own boards so the final floor matches what you pictured rather than a sample on a different species.
Heart Pine in Older Homes
Heart pine and other old pine floors are softer than oak, often carry wide gaps and square nail heads, and have darkened naturally over decades. We sand them with a lighter touch, set protruding nails, and choose a finish that keeps their warm amber tone. Gaps are filled only where the boards will not move enough to crack the filler.
White Oak, Maple and Hickory
White oak takes gray, natural and dark finishes well and hides wear better than red oak. Maple is hard and tight grained, and blotches under dark stain. Hickory is one of the hardest domestic species on the Janka hardness scale and shows dramatic color variation. Each needs its own sanding and finish plan, and we adjust grit, stain and finish type to the wood in front of us.
