The Challenge
Kristine Holmes, a homeowner in Warren, MI, was dealing with a scenario that most contractors dread: a fully deteriorated cast iron trunk line and both stacks buried beneath her home in an extremely confined crawlspace. Aging cast iron is a recipe for cracked joints, root intrusion, and sewage backups — and left unaddressed, it creates serious long-term structural damage and health risks.
To make matters more demanding, the workspace was barely navigable, requiring technicians with the skill, physical endurance, and professional commitment to see the job through without cutting corners.
The original cast iron trunk line and both stacks had reached end of service life, creating high risk of sewer backups and drain failures throughout the home.
The crawlspace offered minimal clearance to maneuver tools, pipe sections, and debris — making every step of the job more physically demanding and technically complex.
Once the old cast iron was cut out, every piece of pipe, fitting, and debris had to be carefully extracted from the crawlspace and hauled completely off the property — with zero mess left behind for the homeowner to deal with.
The Solution
Bison Plumbing dispatched Rick and his helper to handle the full project scope. Their approach was methodical, professional, and thorough — the kind of execution that turns first-time customers into lifelong clients.
Rick and his helper navigated the confined workspace and safely removed the entire cast iron trunk line from the ground up to the footing of the home — a physically demanding job that required patience, technique, and a genuine commitment to quality workmanship.
Both deteriorating cast iron stacks were fully replaced with modern, corrosion-resistant PVC pipe and fittings — bringing the home's entire below-floor drain system up to current standards. This is the kind of thorough work covered under Bison's residential plumbing repairs service.
Every section of old cast iron pipe and fittings was extracted from the crawlspace and removed entirely from the property. No staging area left behind, no follow-up burden for the homeowner — a clean job site is a non-negotiable Bison standard.
The crew cleaned all debris from the crawlspace and surrounding work areas before leaving — the same standard they uphold on every single job, no matter how demanding the conditions. See why customers consistently praise this in our customer testimonials.
Weeks later, Kristine trusted Bison enough to call them back for a completely separate job. Technician Damani replaced the toilet and performed bathroom drain snaking — leaving everything cleaner than he found it. For homeowners wanting to get ahead of recurring buildup, Bison also offers professional hydrojetting services to flush drain lines completely clear. Flexible financing options are available to make any project budget-friendly.

In Her Own Words
2 weeks ago, Bison Plumbing did a fantastic job replacing our cast iron trunk line and both stacks up to the footing of the home within our very tiny crawlspace. They replaced all our piping with PVC pipes and fittings and hauled everything away. They also did an excellent job cleaning up the debris. Shout out to Rick and helper. They worked their butts off to give me the results I needed. They were very professional throughout, and I would walk them back anytime. Bonus for offering a military discount as well.
Today, I had BISON PLUMBING come back to replace my toilet, and to snake out the drain line in the bathroom. Damani did a fantastic job and after he was done, he cleaned up and made everything look better than before. Damani was very professional and I am happy to have him back to work on our house in the future. Kudos to Bison Plumbing for hiring such experienced and professional staff. The only thing I forgot was to ask for my military discount.
