Frequently Asked Questions

When do I need to reroute water or waste lines?
Typically during remodels, additions, or when relocating fixtures. It’s also common when lines are damaged or no longer up to code.

Is re-routing more affordable than replacing?
Often, yes—especially if you only need to change the layout. We’ll help you decide the most cost-effective and long-lasting option.

How invasive is the process?
We minimize disruption whenever possible, and we’re experienced in working under floors, in walls, and through crawl spaces to keep your home intact.

Do I need to shut off water to the whole house?
Yes, temporarily. We always coordinate timing to reduce inconvenience and get your water back on as quickly as possible.
