24/7 Drain Cleaning & Sewer Service in Renton, WA

Downtown Renton and the older valley neighborhoods near the Cedar River have homes from the early 1900s through the 1940s, many built for coal miners and early factory workers.

The Renton Highlands was built largely during and after World War II as housing for Boeing workers, with small homes from the 1940s and 1950s and side sewers now seventy to eighty years old.

Kennydale, Talbot Hill and parts of the Benson Hill area were built from the 1950s through the 1980s with split-levels, ranches and daylight basements.

Newer developments near The Landing, along the lakefront and on the far east side have PVC drains and modern plumbing.

Renton sits where the Cedar River meets Lake Washington, with steep hills rising on both sides of the valley and a long wet season.

The City of Renton maintains local sewer lines, with King County treating the wastewater at its South Plant, and some outlying areas are served by water and sewer districts. In Renton, the private side sewer from house to main is the homeowner's.

From October through April, rain soaks the hillsides and raises groundwater on the valley floor, and cracked side sewers take in water. Roots grow fastest in spring and summer.

Occasional winter freezes and snow can freeze drains in garages and crawlspaces.

Renton began as a coal mining town in the 1870s, and the old neighborhoods near downtown and along the Cedar River have homes built for miners and early factory workers. Many of those houses have very old side sewers, some without cleanouts. Roots, cracks and offsets are common. The valley floor near the river has high groundwater, which seeps into cracked pipe during the wet season.

When Boeing built its Renton plant during World War II to produce B-29 bombers, thousands of workers arrived, and the government built housing on the Highlands plateau east of downtown. Many of those small homes still stand, along with the postwar houses that filled in around them. Their side sewers were built quickly, and after seventy to eighty years many are cracked, offset or full of roots. Some homes have no cleanout at all.

Because Highlands homes are often small, on modest lots, pipe bursting is a popular way to replace an old side sewer without digging up the whole yard.

Kennydale, on the hill above Lake Washington north of downtown, and Talbot Hill, south of the valley, filled in from the 1950s through the 1980s with split-levels and daylight basement homes. Side sewers there are concrete, clay or early plastic depending on age. Big evergreens and maples planted with the homes have grown tall, and their roots find cracked joints.

Renton's neighborhoods climb steep hills on both sides of the Cedar River valley. Homes above the street have side sewers that drop steeply, while some homes below the street rely on pumps. Steep lines can leave debris behind, and hillside soil can shift pipe over time. A camera inspection shows exactly where problems are.

On a wet January night, a family in a 1944 Highlands home finds the bathtub filling with dirty water when the toilet is flushed. There's no cleanout, so the plumber pulls the toilet and runs a cable, clearing roots and debris about thirty-five feet out. The camera shows a cracked, offset joint and a section that has started to sag. The family adds a cleanout and gets a bid for pipe bursting.

Kennydale and Talbot Hill homes often have a lower level with a bathroom and laundry, and those drains are the lowest in the house. When the side sewer slows, the lower bathroom or laundry standpipe is where water usually shows up first.

The Landing, the lakefront and other newer developments have modern PVC plumbing that rarely lets roots in. Calls there are mostly about grease, wipes and hair. New townhomes tied into older mains can occasionally have connection issues, which a camera can confirm.

Downtown Renton's restaurants, The Landing's dining spots and the corridors along Rainier Avenue and the Benson Highway serve Boeing workers, commuters and families. Commercial kitchens need grease interceptors pumped on schedule and lines jetted to prevent backups.

Renton has many large, diverse and multigenerational households. More people means more showers, more laundry and more cooking through the same side sewer. Most of the clogs plumbers pull out of these homes are cooking grease, hair and flushed wipes. A few simple habits, like scraping plates into the trash and using shower strainers, cut down on calls a great deal.

Renton's hills can get snow when the valley gets rain, and occasional arctic air brings hard freezes. Garage drains and crawlspace pipes freeze first. Shut crawlspace vents during cold snaps, put foam on garage pipes and let a faucet run slowly overnight when temperatures drop into the teens.

A side sewer inspection is essential before buying in the Highlands. Watch for roots, cracks, offsets and sags, and ask whether the home has a cleanout. Budget for a possible replacement if the line is original wartime pipe.

Tell them your neighborhood and the home's age, whether it has a lower level or crawlspace and whether there's a cleanout. Mention big trees near the line, how steep the lot is and whether the trouble started during heavy rain.
