Floor Drain Cleaning Service
Call Now (855) 557-9600
Floor drain cleaning removes sediment and biological buildup from trap bowls, clears obstructed drain lines in garage, laundry room, and bathroom floors, and restores the overflow protection these drains provide before water pools and causes damage. Bonded Plumbworks’ licensed plumbers clean the trap bowl, refill it to reseal against sewer gas, and snake the drain line — recommending a trap primer for seldom-used utility drains to prevent the seal from evaporating.
Floor drain cleaning is a plumbing service that removes sediment, debris, and biological buildup from floor-level drainage fixtures found in garages, laundry rooms, basements, utility areas, and bathrooms. Professional floor drain maintenance ensures these critical overflow protection points remain functional during water emergencies. — Bonded Plumbworks
What Is Floor Drain Cleaning
Floor drain cleaning involves removing accumulated sediment, soap residue, laundry lint, and organic matter from the drain grate, trap, and connecting pipe of a floor-level drain fixture. Floor drains sit flush with the finished floor surface and connect to the home’s drain system through a built-in P-trap that holds water to block sewer gas.
Bonded Plumbworks services all residential floor drain types, including cast iron drains in older homes, PVC drains in newer construction, and specialty drains with backwater valves that prevent sewer backups during heavy rainfall. A main sewer line clog downstream of the floor drain forces wastewater to back up through the lowest drain in the system, making floor drain cleaning critical for identifying blockages before they cause basement drain backup or basement sewer backup throughout the home.
Floor drains contain a built-in P-trap that must maintain a water seal to prevent sewer gas from entering living spaces. In the area’s warm climate, floor drains in infrequently used areas can lose their water seal to evaporation within two to four weeks, allowing hydrogen sulfide and methane gases to escape into the home. — Bonded Plumbworks
When to Schedule Floor Drain Cleaning
Floor drain cleaning is needed when water pools around the drain during discharge cycles, when sewer odors emerge from infrequently used drains, and when debris or mold is visible at the grate.
- Water pools on the floor around the drain instead of flowing into it
- Sewer odors emerge from a floor drain, particularly in rarely used rooms
- The laundry room floor floods during washing machine discharge cycles
- Visible debris, sediment, or mold growth around the drain grate
- Water from a broken appliance (water heater, washing machine) does not drain away
- Gurgling or bubbling from the floor drain during toilet flushes
Floor drains that fail during an appliance leak or plumbing emergency can result in significant water damage to flooring, baseboards, and stored items.
In most homes, floor drains are required by the applicable state building codes in areas where water heaters are installed, providing emergency overflow protection. A blocked floor drain near a water heater that fails can allow 40 to 80 gallons of water to flood the surrounding area. — Bonded Plumbworks
How Floor Drain Cleaning Works
Grate Removal and Inspection: We remove the drain grate and inspect the trap area for visible debris, sediment buildup, and signs of root intrusion or pipe deterioration.
Trap Cleaning: The floor drain trap collects sediment, dust, and debris that settles by gravity. We manually clean the trap bowl and refill it with water to restore the sewer gas seal. A floor drain trap primer automatically adds water to the trap at regular intervals, preventing the seal from evaporating in drains that receive infrequent use — a device we recommend during floor drain cleaning for seldom-used utility areas.
Line Clearing: If the blockage extends beyond the trap, we snake the drain line with a motorized cable to clear obstructions in the horizontal pipe run connecting to the main drain. For severe buildup, hydro-jetting scours the line clean. When floor drain cleaning reveals deteriorated cast iron pipe, CIPP lining rehabilitates the drain line from the inside without excavation, restoring full diameter and structural integrity to the pipe serving the floor drain.
Backwater Valve Check: For floor drains equipped with backwater prevention valves, we test the valve mechanism to confirm it seats properly and will prevent sewer backup during storm events.
Flow Test: We pour water into the drain at a measured rate and verify it accepts flow without pooling or backing up.
Backwater valves installed in floor drains use a gravity-operated flapper that allows wastewater to flow out but closes automatically if water attempts to flow back into the home from the sewer line. These valves require periodic cleaning and testing to ensure the flapper mechanism operates freely. — Bonded Plumbworks

FAQ
How much does floor drain cleaning cost? Floor Drain Cleaning typically costs $100 to $400 for most residential jobs. The final price depends on the scope of work, materials required, and site conditions. Bonded Plumbworks provides a written estimate before starting any floor drain cleaning work, so you know the exact cost upfront. Call (855) 557-9600 for a same-day quote.
Why does my floor drain smell like rotten eggs? The rotten egg smell is hydrogen sulfide gas escaping from the sewer system through a dried-out P-trap. Pour water into the drain to refill the trap. If the odor persists after refilling, the drain line may contain decaying organic matter that requires professional cleaning.
Can a clogged floor drain cause flooding? Yes. Floor drains are designed as emergency overflow points. A clogged floor drain cannot accept water from appliance leaks, pipe bursts, or heavy rainfall backup, resulting in standing water and potential damage to flooring and personal property.
Do all homes have floor drains? Not all homes have floor drains in every area, but the State building codes require them near water heaters and in certain utility areas. Older homes may have floor drains in bathrooms, garages, and laundry rooms.
