Marietta Wood Flooring has spent more than 20 years on wood-flooring in Lithia Springs and across the west side of the metro, and a good share of that work starts the same way: a floor that took on water and a homeowner who needs to know what can be saved. We refinish, repair, replace and install hardwood, but the first job in a wet house is an honest read of the boards and the subfloor under them.

Before a single board comes up, we trace where the water went, dry the room, take moisture meter readings and photograph each room so you have a record of what we found. That order matters. A cupped floor sanded flat while it is still wet will crown later, and a floor torn out too soon can mean paying for boards that would have settled back on their own.

This page covers what we look at when creek water or long damp has reached a wood floor, how we decide between restoring and replacing, and what we suggest for owners choosing a new floor in a house that sits low. If you are weighing any of that, we will walk the house with you and put the options in writing.

Sweetwater Creek, the 1904 Gauge and the 2009 Flood

Subfloor being replaced before new wood flooring in a Lithia Springs house.

Lithia Springs is an unincorporated community and census-designated place in northeastern Douglas County, which means Douglas County, not a city hall, handles zoning, permits and code enforcement here. Sweetwater Creek flows through the eastern portion of the community, and Sweetwater Creek State Park borders its southern edge. For anyone who owns a house near that water, the creek’s record is worth knowing before choosing a floor.

A Stream Gauge With More Than a Century of Readings

The federal stream gauge listed as Sweetwater Creek near Austell actually sits in Lithia Springs, and it has operated since 1904. That makes it one of the longer continuous records of how high this creek can climb. When a neighbor says the water has never come up that far before, the gauge is where that claim gets checked.

For floor decisions, a long record is useful because it tells you the creek is not a rare visitor to low ground here. It rises, it recedes and it rises again. We plan floor work on the assumption that a house close to the creek may see water or high humidity again, rather than treating one flood as a freak event.

Beyond the 500-Year Stage

In September 2009, record storms dumped up to 22 inches of rain across northern and western Georgia. On Sweetwater Creek near Austell, just north of Interstate 20, the U.S. Geological Survey found the peak stage was more than 6 feet higher than the estimated peak stage of the 500-year flood. The gauge itself went underwater, and the peak had to be worked out from high-water marks afterward.

FEMA reported that 16,981 Georgia homes were affected by floodwaters across 23 declared counties in that event. Afterward, the Douglasville-Douglas County Water and Sewer Authority used FEMA mitigation grants to buy and demolish 18 floodplain properties in the Sweetwater Creek area. A 500-year label describes odds, not a promise, and 2009 showed how far past it this creek can go.

Woodrow Wilson Park and Helene in 2024

Douglas County’s Woodrow Wilson Park, at 6635 Mt. Vernon Road, lies in the 100-year floodplain of Sweetwater Creek, and the county warns that it can flood with no advance notice. During Helene in 2024, the National Weather Service reported that Sweetwater Creek inundated the park’s athletic fields, and Mt. Vernon Road was closed at the park. Floodwaters also reached homes along Brook Forest Road and Wren Circle.

That was fifteen years after the 2009 flood, and it is a reminder that floodplain maps describe real ground. If your house sits near the creek or its tributaries, it is worth pulling up the county’s flood map before you pick a floor, and it is worth knowing where your floors stood during both events.

When Creek Water Reaches a Wood Floor

Wood is hygroscopic: it takes on moisture from standing water, from wet air and from a damp subfloor, and it swells as it does. What a floor looks like the week after a flood is rarely what it will look like a month later. That is why we measure before we recommend anything.

Cupping, Crowning and Buckling

Cupping shows up when the bottom of each board is wetter than the top, so the edges rise above the center. Crowning is the reverse, and it often appears when a cupped floor was sanded before it dried, leaving the middle high once the wood shrinks back. Buckling is the severe case, where boards lift off the subfloor entirely and the flooring cleats or staples pull loose.

Cupping on its own can relax as the floor dries, which is one reason we do not rush a sander onto a damp floor. Buckling usually means the fasteners and often the boards themselves have to come up. Board gapping after drying is also common, since swollen wood can crush its own edges and then shrink smaller than it started.

Drying, Reading and Recording

We take moisture meter readings in each affected room and compare them with readings from a dry area of the same house, so the target reflects your home rather than a guess. We run a dehumidifier where needed, check the subfloor and joist area where we can reach it, and look for water stains, dark board ends and hollow spots that point to where the water sat longest.

Every room gets photographed and measured as we go. That record helps you see why one room can be sanded and another cannot, and it gives you something concrete to show anyone who asks what the floor looked like before work began. We do not tell you what any policy will pay; we give you an accurate account of the floor.

What Lingers After the Water Is Gone

Floodwater carries silt, and it can leave staining that runs deeper than a sanding pass will reach. Boards that stayed wet for days may also soften at the tongue and groove, which shows up later as squeaks or movement underfoot. We check for both before we promise a refinish.

Damp air after a flood matters too. A house that stays humid for weeks can push moisture into rooms the water never touched, so we read those floors as well rather than assuming only the flooded room needs attention.

Replace or Restore: Deciding After a Flood

Not every flooded floor needs to be torn out, and not every floor that looks fine has come through undamaged. The decision rests on moisture readings, how long the wood sat wet, what the subfloor shows and how much wood remains above the tongue.

When a Floor Can Be Saved

If the boards dry back close to the reference readings, lie reasonably flat and still have enough wear layer above the tongue, we can often sand and refinish. Solid hardwood gives us more room here than an engineered floor, since a thin engineered wear layer may not survive a full sanding. We walk the grit sequence carefully on a floor that has moved, so we are not grinding away wood to chase a ridge that will settle.

Where only part of a room was damaged, we cut out the ruined boards and lace in matching ones, weaving them into the existing run so the repair does not read as a patch. On red oak or white oak, we use stain samples on the new and old wood together before the whole floor is finished.

When It Has to Come Out

Boards that stay buckled after drying, show rot or softness, or have delaminated in the case of engineered flooring are usually past saving. The same goes for a floor whose subfloor stayed wet long enough to swell or break down. Laying new hardwood over a damaged subfloor only moves the problem up a layer.

When a room does need replacing, we remove the old floor, carpet pad or tack strip, confirm the subfloor is dry and sound, and then install. Because houses in Lithia Springs vary widely in age, we also check the build year first. Federal lead-safe rules under the EPA RRP Rule reach homes built before 1978, and that changes how any sanding or demolition is set up.

Water Damage in a Rental

Renters make up a large share of households in Lithia Springs, so we also work for landlords after a flood or leak. We provide itemized floor-damage estimates, room by room, that an owner can set against a move-out inspection or a repair budget. The same measured record we keep for homeowners serves here as well.

Choosing Floors for a House Near the Creek

Most owners here live in detached houses; 87.4 percent of owner households do, according to Census estimates. The 1980s were the largest building decade in the community, at 23.8 percent of housing units, and a lot of those homes now carry floors that are ready for a first or second refinish. If yours sits on low ground near Sweetwater Creek, the choice of material deserves a little more thought.

Solid Hardwood or Engineered

Engineered wood holds its shape better than solid hardwood when humidity swings, because its layered core resists the swelling that makes solid boards cup. For a terrace level, a basement or any floor below grade, engineered is what we recommend, since solid wood does not belong there. A glue-down engineered floor with a proper vapor retarder is a common choice for those rooms.

On upper floors farther from the water, solid hardwood still makes sense and can be sanded many times over its life. Harder species with a higher Janka hardness, such as hickory or white oak, also hide wear well in busy rooms. We will talk through the tradeoffs with the actual room in front of us.

Finishes and Acclimation

New wood needs time to acclimate to the house before installation, and in a home that has been flooded we confirm the air and subfloor have settled first. We keep the expansion gap at the walls so the floor has room to move, and we hide it under quarter round or baseboard. For finishes, we choose clear coats by their federal VOC category and match the sheen level to how the room is used.

Replacing Carpet, Laminate or Vinyl

Many flooded rooms started out as carpet, laminate or luxury vinyl plank, and owners often take the chance to switch to wood. We replace those floors with hardwood, stairs included, and price stair treads and stair risers tread by tread rather than by the square foot. If a room is likely to see water again, we will tell you plainly whether wood is the right call there at all.

Before any project, we also confirm what Douglas County requires for your address, since permits and floodplain rules are the county’s call. Then we put the plan, the materials and the price in writing so you can decide with the facts in hand.
