FAQs
How do I know if my main water or sewer line in Kelso needs a full replacement?
Common warning signs include repeated backups, gurgling sounds in toilets or drains, unexplained soggy spots in the yard, a sudden spike in water bills, or visible rust flakes in water. Our technicians can run a camera inspection to determine whether the pipe is merely clogged or has structural damage such as cracks, collapsing sections, or severe corrosion that warrants full replacement.
What are the most frequent causes of main line failure in Kelso homes?
In Kelso, older homes still have many original galvanized or clay pipes that naturally deteriorate over time. Other leading causes are root intrusion from our region’s mature trees, ground shifting due to heavy winter rains, damage from nearby construction, and buildup of grease or scale. Freezing temperatures can also crack weakened pipes, making replacement the safest long-term solution.
Which replacement methods do you offer and how do I know which one is right for my property?
We specialize in both traditional open-trench replacement and trenchless options such as pipe bursting and cured-in-place pipe (CIPP) lining. Open-trench is chosen when the pipe is severely collapsed or mis-aligned, while trenchless methods are ideal for stable soil conditions and when you want to preserve landscaping, driveways, or sidewalks. After our inspection, we explain each option, its cost, and any yard restoration involved so you can make an informed decision.
Will I need a permit for a main line replacement in Kelso, and do you handle that process?
Yes. The City of Kelso requires permits for any work on a service line that connects to the municipal water or sewer system. We take care of permit applications, coordination with city inspectors, and scheduling mandatory inspections. You’ll receive copies of all approved paperwork for your records once the job is complete.
How long does a typical main line replacement take, and will my water be shut off during the work?
Most projects are completed in one to three days, depending on pipe length, depth, and the chosen replacement method. Water is usually shut off for only a few hours during the actual pipe switchover. We always give advance notice, provide temporary water solutions if needed, and restore service as quickly as possible to minimize disruption.
How much does a full main line replacement cost in Kelso, and do you offer financing?
Costs vary based on pipe material, length, depth, and the replacement technique. In Kelso, open-trench replacements average $120-$180 per linear foot, while trenchless options range from $90-$150 per foot. After our inspection, you’ll receive a written, fixed-price quote with no hidden fees. We partner with local lenders to offer low-interest financing and accept major credit cards, ensuring the project fits your budget.
