Cupping And Buckling In Hardwood After A Leak
Cupping is boards rising at their edges after they take on water from below, and buckling is the floor lifting off the subfloor entirely. We find and stop the water source first, dry the floor while reading it with a moisture meter, and only then decide whether the boards can be flattened and sanded or have to be replaced. Sanding a cupped floor too early leaves it crowned once it finally dries.
Seasonal Cupping And Winter Gaps In Oak Floors
Wood swells in a humid summer and shrinks when the furnace runs, so many floors cup slightly in August and open winter gaps between boards in January. Some of that board gapping is normal movement and needs no repair at all. We tell you which part is seasonal, which part points to a basement or crawlspace moisture problem, and how a dehumidifier or humidifier evens out the swing.
Wood Floors After A Sump Pump Failure Or Burst Pipe
A failed sump pump floods a finished basement from below, and a burst pipe soaks a floor from the room above. We document the damage room by room with moisture readings and photos for the adjuster, dry what can be saved and replace what cannot. The Maryland Insurance Administration notes that a sudden burst pipe is generally covered while a slow leak generally is not, so the record of when the water arrived matters.
Squeaky Floorboards, Nail Pops And Loose Face Nails
Squeaky floorboards usually come from boards rubbing on loose fasteners or a subfloor that has pulled away from a joist. We find the movement, refasten from above or below, and set and fill any face nails working up through the finish. A nail pop standing proud of the surface catches socks and eventually lifts the board beside it.
Pet Urine Stains That Reached The Subfloor
Urine that sits in oak turns the wood black, and once it has soaked through the board it often stains the subfloor and holds its odor. Sanding cannot lift a black stain that deep, so we cut out the affected boards, seal or replace the subfloor underneath, and weave in new boards before refinishing. Gray surface marks sometimes sand out; black ones rarely do.
Powderpost Beetle Holes And Frass In Floorboards
Small round exit holes with fine, flour-like powder called frass beneath them are the sign of wood-boring insects such as the powderpost beetle. We help confirm whether the activity is old or current, send you to a pest professional when it is live, and replace the damaged boards once treatment is done. Patching over active damage only moves the problem to the next board.
Termite Damage Found Under The Floor
Termite damage often shows as boards that feel soft, sink underfoot or break when lifted, with hollowed grain or mud tubes underneath. We open the floor, check the boards, subfloor and joists, and schedule our repair behind the termite treatment rather than ahead of it. Once the structure is sound, we replace and blend the damaged area so it does not read as a patch.
Peeling Polyurethane Over An Old Waxed Floor
Polyurethane will not bond to wax residue, so a fresh coat applied over a floor that was once waxed can peel in sheets within weeks. We test for wax before any recoat and, where it is present, sand the floor to bare wood so the new finish has clean fibers to grip. A quick recoat over wax is one of the most common failed jobs we are asked to fix.
Orange Oak And Ambered Oil-Based Finishes
Red oak under an oil-modified polyurethane ambers with age, which is why so many floors from the 1990s and 2000s now look like orange oak. We sand back to bare wood and choose a new color and finish from samples, often a waterborne polyurethane that stays clearer over time. Toning down orange without a full sanding is rarely possible, and we will not pretend otherwise.
