Answers to the most frequently asked sewer and drain questions from Mercer Island property owners.
We use a specialized waterproof camera that is inserted into your sewer line through a cleanout. The camera transmits real-time video that shows us the exact location and nature of any blockage, crack, offset joint, or root intrusion. This lets us recommend the most cost-effective repair for your Mercer Island property without any excavation.
Absolutely. Tree root intrusion is one of the most common causes of sewer line damage in Mercer Island, WA. Roots seek out moisture and can penetrate tiny cracks or joints in sewer pipes, eventually causing blockages and pipe collapse. Our crews remove roots with hydro jetting and can reline pipes to prevent future intrusion.
Sewer line repair costs in Mercer Island typically range from $1,500 to $5,000 for standard residential repairs and $5,000 to $15,000 or more for full replacements. Factors include pipe material, depth, length of damaged section, and whether trenchless methods can be used. We provide free camera inspections with detailed, written estimates before any work begins.
Common warning signs for Mercer Island homeowners include multiple slow drains, gurgling toilets, sewage odors in the yard or basement, soggy patches in the lawn, and recurring drain backups. If you notice any of these, call us for a sewer camera inspection to diagnose the problem before it becomes a costly emergency.
Yes. Our Mercer Island, WA teams are equipped for drain cleaning at any scale — from residential kitchen and bathroom drains to commercial restaurant grease lines, multi-unit buildings, and industrial facilities. We carry equipment rated for pipes from 1.5 inches to 12 inches in diameter.
Most residential drain cleaning jobs in Mercer Island, WA take 30 minutes to 2 hours depending on the severity of the clog and the number of drains affected. Main sewer line cleaning may take longer.

"Our laundry drain kept backing up no matter how many times we used store-bought cleaners. One professional cleaning visit and the problem has not come back in six months. Wish I had called sooner."
"Had multiple drains backing up at the same time. Turned out to be a collapsed section of our sewer line. They found it with the camera, gave us options including trenchless repair, and had it fixed within two days."
