Drain Backup and Gray Water Cleanup in Marysville, WA

Gray water does not stay gray for long. In Marysville homes, laundry rooms are often off the garage, or upstairs near the bedrooms in some newer two-story houses, and a clogged standpipe can send a full washer drain cycle across the floor and under the wall into a hallway or a room below. Kitchen sink drains in many 1990s and 2000s homes have years of grease buildup in the branch line, and the dishwasher drains straight into that pipe. The water is warm, soapy and full of food or lint, and in a closed-up house during a cool, damp Marysville winter, it sits in the subfloor and drywall where it breeds odor fast.

In the first hour, gray water is mostly on the floor or in the cabinet and can be extracted and cleaned. By 24 hours, it has wicked into the baseboards, the bottom of the drywall and the particleboard under the washer or sink. By 48 hours, gray water left in place is treated as category 3, bacteria and odor have grown and mold can start. After a week, cabinet bases and laminate floors have swollen, the wall cavity smells sour and more material has to be removed than would have been at the start.

Because gray water is category 2 when it is fresh, more can be saved than with sewage if the job starts within a day. Tile, sealed concrete in garages and laundry rooms, and vinyl that water did not get under can be cleaned and dried in place. Solid wood and plywood cabinet boxes usually dry with air blown into the open cabinet and toe kick. Drywall that wicked only a few inches can be cleaned and dried through small holes at the base, and wood framing and subfloor are treated with an antimicrobial and dried with dehumidifiers.

Some materials do not survive gray water. Carpet pad in a laundry room or next to a kitchen is usually removed, and carpet that soaked for more than a day or two may go too. Particleboard under washers, in sink cabinets and in vanity bases swells and is replaced. Laminate flooring that took water at the seams rarely flattens again. If the gray water sat 48 hours or more, it is handled as category 3, and porous materials it touched are removed the same way as after a sewage backup.

Drain backups happen in every Marysville neighborhood. In Cedarcrest, Getchell Hill and Whiskey Ridge, some newer two-story homes have upstairs laundry rooms, so a clogged standpipe can come through a ceiling below. In Smokey Point and Lakewood, many homes have a laundry room off the garage, where gray water runs across the garage slab and soaks stored boxes and the bottom of the drywall. Older homes near Downtown often keep the laundry in a utility room over a crawlspace, where water passes through the floor and onto the insulation.

The same calls come in from nearby towns. In Everett, older homes in north Everett often have kitchen and laundry drains that are decades old. In Mukilteo, many Harbour Pointe homes from the 1980s and 1990s have kitchen and laundry branch lines that may be due for cleaning. In Arlington and Stanwood, a laundry room off the garage is a common place for a backup to show up. One call connects you with a local restoration pro who extracts, cleans and dries.
