Humidity Cupping and Board Gapping
Cupping is when board edges rise above the centers because moisture is coming from below, often a damp crawlspace in a humid Georgia summer. We find the moisture source, dry the floor and track readings until it settles. Most cupped floors flatten on their own once dry, which saves you from sanding away wood you still need. Winter gapping is the same movement in reverse and rarely needs more than patience.
Vacant-House Cupping
Houses that sat empty with the HVAC off through a Georgia summer often cup across every room at once. We check the crawlspace, the vapor retarder and the dehumidifier before judging the floor, because the fix for a house that lost climate control is usually drying, not replacing. That distinction matters to sellers and investors pricing a vacant property.
Subterranean Termites and Powderpost Beetles
Subterranean termites leave mud tubes and hollow boards; powderpost beetles leave pinholes and fine frass; the old house borer leaves larger oval exits. We read the damage pattern, wait for treatment, then cut the affected boards back to sound wood and replace them. Floor repair after pest damage is carpentry, not a cosmetic touch-up.
Appliance Leaks and Water Damage
A dishwasher, refrigerator line or supply valve can soak boards for weeks before anyone sees a stain. We trace how far the water traveled, dry the floor and subfloor, and photograph readings room by room before deciding what comes up. Dried boards are often saved; boards left wet too long are replaced and laced in.
Pet Urine Stains Gone Black
Pet urine that sits in oak reacts with the wood and turns it black, and that color goes deeper than any sanding can reach. We sand first to see what remains, then replace the boards that stay dark. Trying to bleach or stain over deep pet urine stains usually leaves a gray shadow that still shows.
Squeaks, Loose Boards and Soft Spots
Squeaks usually mean boards or subfloor moving against fasteners or a joist. We locate the movement from above and, where there is a crawlspace, from below, then refasten or shim it. A soft spot is different, and we check it for rot, termite damage or a failed subfloor before covering anything.
Hollow-Sounding Glue-Down Engineered Floors
Glue-down engineered floors that sound hollow underfoot have lost their bond to the slab or subfloor. We map the hollow spots, inject adhesive where the bond can be restored, and replace boards where it cannot. Left alone, those loose areas crack at the joints and eventually lift.
Swollen Laminate and Vinyl Plank
Laminate swells at the edges when water reaches its core, and floating vinyl plank can pull apart when the room moves or the expansion gap was pinched. Neither can be sanded. We replace the damaged run or, when a homeowner is ready, take the whole floor up and install hardwood in its place.
Deep Scratches, Dents and Traffic Lanes
Traffic lanes turn gray once foot traffic wears through the finish into bare wood. Deep scratches and dents from furniture or pets go into the wood itself. Both need a full sand to the grain; a recoat alone would seal the damage under a fresh, shiny layer.
Peeling, Tacky or Cloudy Finish
A finish that peels, stays tacky or goes cloudy usually failed because of contamination, incompatible coats or moisture. We identify the cause first, whether old wax, a cleaning product or humidity during curing, then strip and refinish so the next coat cures properly.
