When your home’s plumbing stack begins to show signs of wear, leaks, or corrosion, it’s not something you can afford to ignore. Your plumbing stack is the heart of your home’s drainage system. It quietly directs wastewater away from your sinks, showers, and toilets every single day. At Castlewood Plumbing, we specialize in stack replacement services in Wildwood, MO, and the surrounding areas, ensuring your plumbing system flows freely and efficiently.

What Is a Plumbing Stack and Why It Matters

Your plumbing stack, sometimes called a drain stack or soil stack, is a vertical pipe that connects all your home’s drain lines to the main sewer line. It also serves as a venting system that balances air pressure in your plumbing, allowing water and waste to flow smoothly.


When your stack starts to fail, you may notice gurgling sounds from your drains, slow drainage, or even unpleasant odors. These issues often mean your stack is corroding, cracked, or blocked, especially if your home is more than 30 years old.



That’s where Castlewood Plumbing comes in. Our experienced plumbers know how to identify the root of the problem and provide reliable stack repair or full replacement that restores your plumbing system to perfect working order.

Signs You May Need Stack Replacement

If you’ve noticed any of the following issues, it’s time to have your plumbing stack inspected:

  • Frequent drain backups or clogs throughout multiple fixtures
  • Sewage smells or damp, musty odors in your basement or walls
  • Visible rust, corrosion, or leaks around the stack
  • Water stains or bubbling paint near your bathroom or kitchen walls
  • Slow drainage in multiple drains at once
  • Old cast-iron stacks, which typically last 50–70 years but corrode from the inside

Ignoring these warning signs can lead to serious water damage, structural issues, or even health hazards due to mold and sewer gas leaks. When you call Castlewood Plumbing, our experts perform a detailed camera inspection to pinpoint the issue and provide a clear, upfront estimate before any work begins.

Our Proven Stack Replacement Process

We treat every stack replacement as a precision job because it is. Here’s how we ensure it’s done right:

1. Inspection and Diagnosis

We start with a comprehensive plumbing inspection, often using camera technology to assess the interior condition of your drain stack. This helps us identify cracks, corrosion, or buildup that may not be visible from the outside.

2. Honest Consultation and Upfront Pricing

We’ll walk you through our findings and explain your options clearly. You’ll get transparent, upfront pricing with no surprises, just honest recommendations based on what’s best for your home.

3. Careful Removal of the Old Stack

Our team removes the old pipe safely and efficiently, protecting your walls, floors, and surrounding plumbing fixtures during the process.

4. Expert Installation of a New Stack

We install a high-quality replacement pipe, typically made of PVC or ABS, designed to last for decades. These modern materials resist corrosion, cracking, and leaks.

5. Final Testing and Cleanup

Before we leave, we thoroughly test your plumbing system to ensure everything drains and vents perfectly. Then we clean up the workspace so it looks like we were never there, except for your brand-new, efficient plumbing stack!
