Our Main Water Service Solutions

  • Main Line Replacement
    When your existing water line is old, corroded, or repeatedly leaking, a full main line replacement is the safest solution. We replace pipes from the city meter to your home or business using durable, long-lasting materials that ensure consistent water flow and prevent future leaks. Our experienced Portland plumbers handle the entire process, including excavation, pipe installation, and testing to guarantee a reliable water supply for years to come.

  • Water Service Upgrades
    If your property struggles with low water pressure or outdated piping, upgrading your main water line can make a dramatic difference. We install appropriately sized pipes to meet the demands of modern households or commercial buildings. This ensures stronger water flow, better performance for appliances, and improved efficiency for everyday use.

  • Leak Detection & Repair
    Hidden leaks in your main water line can cause serious damage and drive up water bills without obvious signs. Our team uses advanced leak detection technology to locate the source quickly and repair it with precision. Whether it’s a minor repair or a section replacement, we restore your system safely and efficiently.

  • Trenchless Water Line Installation
    When traditional excavation isn’t ideal, trenchless water line installation offers a minimally invasive solution. We replace or upgrade your main water line without extensive digging, reducing disruption to your yard, landscaping, or driveway. This method is faster, cleaner, and often more cost-effective while still meeting Portland plumbing codes.

  • Inspection & Testing
    Before and after any replacement or upgrade, we thoroughly inspect and test your main water line to ensure it operates reliably and meets all local code requirements. This includes water pressure checks, leak detection, and system flow testing. Our goal is to provide peace of mind knowing your water supply is safe, efficient, and fully functional.

  • Residential and Commercial Expertise
