Sewer Stacks

Comprehensive sewer stack inspection, repairs, and replacement for safer plumbing systems.

Your sewer line is one of the most important parts of your property, but it’s often ignored until there’s a problem.

A cracked stack or failing line can lead to sewage leaks, foul odors, or even a sewer backup in the basement. That’s why regular inspections and fast repairs or replacements are so important. They protect your home or business from expensive (smelly) damage and keep your plumbing system running the way it should.

Our team helps homeowners and business owners alike handle these issues with expert sewer stack replacement and repair services. Whether you’re dealing with older cast iron pipes that are prone to cracking or a more modern system that’s run into issues, our team is here to find the problem and fix it–fast.

Why Sewer Stack Problems Can’t Wait

A damaged sewer stack is a risk to your property and your health. Signs of trouble include:

These are warnings that something deeper is going on inside your plumbing system. Ignoring them could mean water damage, foundation issues, or exposure to harmful sewer gases.

Cast Iron Plumbing Repair and Replacement

Many buildings in the area still rely on cast iron stacks, especially those built before 1980. While the cast iron is strong and durable, nothing lasts forever. Over time, it corrodes from the inside out, restricting flow and weakening the pipe walls.

When that happens, you need cast iron plumbing repairs fast to prevent a catastrophe. In some cases, we can patch or reinforce sections of pipe that are still structurally sound. But if the corrosion has spread, or if the pipe has fully cracked, a full repair or stack replacement may be necessary. Catching these issues early often means you can avoid a complete failure and the sewage mess that follows.

What Happens During a Sewer Stack Replacement?

The process may sound intimidating, but with the right professionals, it’s straightforward. First, we assess the condition of your plumbing system using inspection tools that allow us to see inside the pipes. If we determine that replacement is needed, we remove the damaged area and perform a complete cast iron pipe repair that meets today’s standards for safety and durability.

And because sewer stacks connect to every drain in your home or building, replacing them not only solves current problems but also helps prevent future ones—like slow drains, recurring clogs, or that dreaded sewer backup in the basement.

If the unmistakable acrid smell doesn’t give it away, bubbling or gurgling noises from your drain are another sign that it’s time to proceed with a new soil stack repair or installation. The cost can vary greatly, and it is best to contact a #1 Rated Master Plumber to get your soil stack installation done quickly and correctly.

The standard range of a soil stack replacement or repair is usually $1,225 – $2,869.

A “stack” is the vertical section of a plumbing drainage system of soil, waste, or vent piping rising through one or more stories of a building. The stack is the largest vertical pipe into which all the horizontal pipes drain or vent.

Absolutely! A cracked sewer pipe behind a wall can raise humidity levels to the point where mold can become an issue. If you notice mold growth, musty smells, or sewer odors, you likely have a break in your sewage drain pipes.

Many houses with cast iron plumbing were built before 1980. In some cases, the metal will continue to deteriorate as wastewater runs through it. The cast iron on each side of the pipe can crumble or crack at the weakest point or the thinnest part of the casting where the sections are molded. Schedule an appointment immediately if you need to replace your cast iron plumbing stack.
