The Finished Basement on Maple Street
One McCordsville homeowner called us on a Sunday morning after the main line backed up through the basement floor drain. By the time we arrived, roughly two inches of black water sat across 600 square feet of carpeted living space. The carpet was newer, less than three years old, and the homeowner asked if we could extract, sanitize, and save it. We had to say no. Carpet and pad that have been saturated by Category 3 water are not salvageable under IICRC Category 3 protocols, full stop. The fibers trap bacteria, the pad acts like a sponge, and no amount of hot water extraction kills what soaks into the backing.
What we did save: the engineered hardwood transition at the stair landing, because it sat half an inch above the waterline. The drywall came out 24 inches up, which is the standard cut height for contaminated water that has not wicked higher. We tested the bottom plates with a penetrating moisture meter before committing to a number, and the framing read dry enough to clean, treat with an EPA-registered antimicrobial, and leave in place.
The harder loss in that basement was the homeowner's home office setup: a particleboard desk, a bookshelf full of paperbacks that had wicked water up the spines, and a leather sectional whose wood frame had been sitting in the contamination for at least 12 hours. The leather itself looked fine on top, but the underside fabric and the frame told the real story. We documented every item with photos and a written inventory before disposal, which made the insurance conversation cleaner. That documentation step is something McCordsville Metal Roofing crews do on every job, because memory is not evidence and adjusters need paper.
The Townhouse with the Finished Bathroom
A townhouse owner in McCordsville called after a toilet supply line failed while she was at work. The overflow ran for hours and pushed contaminated water under the vanity, into the hallway carpet, and down through the floor into the kitchen ceiling below. This was a textbook case of why toilet overflow events escalate fast. We replaced the vanity (particleboard sides had already started to swell), the baseboards on three walls, and the section of kitchen ceiling drywall directly below the bathroom. The tile floor itself stayed, but every bit of grout in the affected zone was scrubbed, sanitized, and resealed.
The hardwood in the hallway was the hard conversation. The homeowner wanted to save it. We brought in a moisture map, showed her the readings climbing toward the subfloor, and explained that solid hardwood over a contaminated subfloor would cup, crown, and eventually need replacement anyway. She agreed to pull it. The subfloor below was OSB, which we cut out and replaced in the affected area. OSB swells and delaminates once sewage hits it, and gluing new flooring to a compromised substrate is a callback waiting to happen.
The Pattern: What Almost Always Goes
After hundreds of McCordsville sewage jobs, the replacement list rarely surprises us. Porous materials lose, non porous materials win.
- Carpet, pad, and carpet tack strip in the affected area
- Drywall, typically cut 24 inches above the waterline, higher if wicking is measured
- Insulation behind that drywall, batt or blown
- Particleboard cabinetry, vanities, and furniture that touched the water
- Engineered wood flooring and laminate, because the cores swell
- Upholstered furniture, mattresses, and porous decor
What we work hard to save: solid hardwood (case by case), tile and stone with sealed grout, structural framing once dried and treated, solid wood cabinets after removal of toe kicks, and metal fixtures. The decision usually comes down to porosity, dry time, and whether contamination reached the back side of the material.
The Conversation You Should Expect
When a McCordsville Metal Roofing project manager walks a sewage loss with you, the goal is not to maximize demolition. It is to scope an honest line between what can be defensibly saved and what has to go. We bring meters, we bring photos, and we bring the IICRC standard in writing. A homeowner in McCordsville recently asked us why a different company had quoted half the scope. The answer was simple: they were not planning to test the framing, and they were leaving the insulation in place behind walls that had been splashed. That is a callback, a mold claim, and a lawsuit waiting six months out. We would rather have the harder conversation now.
The Commercial Kitchen Backup
A small restaurant in McCordsville had a grease and sewage backup come up through a floor sink during dinner service. The owner closed for the night and called us before midnight. Our crew was on site in most cases within 2 hours, and this one was no exception. Commercial jobs have different stakes: health department inspections, employee safety, and lost revenue every hour the doors stay shut.
What had to be replaced: the lower three feet of FRP wall paneling behind the dish pit, the wood blocking behind it, and a stainless prep table whose particleboard underframe had wicked contamination. What we saved: the quarry tile floor (sealed, non porous, scrubbed and sanitized), the stainless walk in shelving, and most of the lower cabinets after we removed and replaced the kickplates. The owner reopened in four days. A scope that replaced everything in the splash zone would have stretched that to two weeks.
One detail from that job worth sharing: the gaskets on the walk in cooler door were splashed during the backup. Rubber is technically non porous, but the gasket channels trap debris and the foam core behind the rubber is absorbent. We replaced both gaskets rather than try to sanitize them in place. On a residential job that might feel like overkill. In a kitchen that gets inspected, it is the only defensible call.
Why the Cut Heights Matter
A common question from McCordsville homeowners: why are you cutting drywall higher than the water line? Sewage water wicks. Gypsum pulls moisture upward through capillary action, and the contamination rides along with it. We document the readings before we cut, and we will show you the meter so you can see why the line is where it is. For deeper context on how walls get evaluated, our notes on drywall removal after water damage walk through the same logic.
The other reason we cut clean and high: rebuild. Drywall installers tape and float much cleaner against a straight horizontal cut than a jagged one, and your repaint looks better when the seam falls at a logical height.
