Frequently Asked Questions

What should I do if my basement is flooding in Saint Joseph?

Basement flooding in our area is often linked to overwhelmed sewer lines or foundation drainage issues. For immediate safety, shut off power to the affected area if possible. Then, contact us. As a full-service plumbing and excavation company, we can quickly diagnose the source—whether it's a cracked sewer pipe, a failed sump pump, or a blocked exterior drain. Our excavation capabilities allow us to repair or replace damaged underground lines efficiently, helping to prevent future water intrusion and protect your home's foundation.

Do you offer trenchless sewer repair in Saint Joseph?

Yes, we frequently use trenchless excavation methods for sewer repair and replacement in Saint Joseph. This approach allows us to fix or install new sewer lines from your house to the city main with minimal digging. Instead of tearing up your entire driveway or yard, we work through small access points. This saves significant time, reduces restoration costs, and preserves your landscaping. We'll assess your specific situation to determine if trenchless repair is the right, long-lasting solution for your property.

Can you handle both the plumbing and excavation for a new water line?

Absolutely. As a combined plumbing and excavation company, we manage the entire project from start to finish. Our Master Plumber handles all the interior connections, fixture work, and code-compliant piping, while our expert excavator operator manages the trench digging and careful burial of the new line. This single-team approach ensures seamless coordination, prevents delays between contractors, and provides you with one point of accountability for the entire water line installation or replacement.
