Under the sink, behind the tub, or through the walls—pipe replacement costs for small projects run the gamut. Here's what to know.
Plumbing costs depend on your project and location. Check with a local pro for your specific job.
Rerouting a plumbing vent costs $1,500 on average, but your total depends on the materials, repairs, and labor your project requires.
The location of your vent pipe and the extent of wall or roof work needed will determine your final project complexity.
You should also account for the cost of drywall repairs, roofing repairs, and building permits when you create your project budget.
Hiring a local plumbing professional prevents sewage backups and hazardous gas leaks from improper vent pipe installation or incorrect pipe slope.
Vent pipe replacement costs $1,500 on average, though it can range from as little as $500 to as much as $5,000. The piping of a household is a modern miracle, as it utilizes the air flowing throughout the house at any given time to keep your lines moving. A plumbing vent pipe helps keep this process going by maintaining the air pressure throughout the pipes. But if you’re remodeling a bathroom, repiping a home, or even moving a wall, you may need to reroute your plumbing vent. Learn all the factors that contribute to vent pipe replacement costs.
The total cost of rerouting a plumbing vent depends on the materials used, any repairs you’ll need after the move, and overall labor costs.
There are two types of professionals you can hire to tackle this job, either a plumber or a handyperson. Hiring a local licensed plumber will cost anywhere from $45 to $200 per hour. This ensures the job is bonded and warrantied, but you may need to hire a handyperson anyway if there's drywall damage. Contact at least three plumbers for quotes so you can get the best price possible.
The average hourly cost of a handyperson is about $40 to $140 per hour if you choose to opt for a handyperson to take on this project. Not all handypersons are licensed, so warranties on work are not guaranteed. But you wouldn’t likely have to hire someone else to tackle the repairs needed to complete the job.
Shaddai Plumbing team is great! They are very professional, they keep their word, they complete job without delays. Great quality. We had to replace old water pipes across 2-story home and their service was great. We asked to add additional water switches to be able to switch hot/cold water on and off in separate parts of home - and they did it. Now if it will be leak or other problem - we can switch off kitchen area, or second floor without impacting other parts of our home. Highly recommended!
| Repair Types | Cost |
|---|---|
| Hole repair | $300–$900 |
| Roof pipe rerouting | $1,070 |
| Flooring repairs | $200–$600 |
Repairs may be needed if rerouting the pipes means cutting into the floor, roof, or walls. The cost to repair holes in drywall can range anywhere from $300 to $900 or more, depending on the size and severity of the holes. Hiring a handyperson to reroute the plumbing vent may mean that the drywall repair price is included in the project, rather than coming in separately.
If you’re rerouting your plumbing vent pipe on your roof, then you can expect to pay around $1,070 on average for roofing repairs. Patching up a roof requires more material to ensure Mother Nature doesn’t make a surprise visit to your living room one day.
Floor repairs will come down to the flooring material you currently have. The average cost of flooring repairs is around $400 but can range from $200 to $600.

Simple projects that only require a small PVC pipe, a little cement, and a cap will cost significantly less than a larger scope project. Small projects include rerouting an easily accessible plumbing vent underneath a sink or in a basement.
More extensive projects, such as rerouting a plumbing vent to exhaust in a different location of the home, will cause a significant price hike. This type of project includes the cost of drywall repair, roof repair, and much larger amounts of piping.
| Materials | Average Cost |
|---|---|
| CPVC piping | $1 per linear foot |
| Pex piping | $1.15 per linear foot |
| Copper piping | $3 per linear foot |
| Primer | $10–$20 per gallon |
| Cement | $20–$30 per gallon |
| Flux | $5–$15 per 8 oz. |
| Solder | $20–$35 per 8 oz. |
Doing work on the roof may require a building permit. You should ask your local municipality if this is necessary, as it varies from city to city. Minor building permits for this type of project cost anywhere from $50 to $500 on average.

Hiring a local plumber costs $45 to $200 per hour, but it’s not a cost to skimp out on. Replacing a vent pipe is a complex task that requires specialized knowledge, and mistakes can lead to costly repairs or health and injury hazards.
Always hire a professional plumber to do plumbing work in your home, but it’s particularly important for vent pipe replacement. Here’s why:
Improper vent pipe replacement can lead to sewage backups, water damage, or hazardous gas leaks from sewage.
You’ll potentially spend more on water damage repairs due to a DIY mistake than you would on hiring a plumber to swap out your pipe.
Repairs can require cutting into the walls or flooring, and mistakes have the potential to cause costly damage or injury.
Vent pipe installations can require roof work, and pros know how to manage the fall risk and safely utilize tools on a pitched roof.
Vent pipe installation requires specialized knowledge, and a small mistake, such as the incorrect pipe slope, can cause serious issues.
Professional plumbers know how to look out for hidden issues, so they can fix the entire problem and not just part of it.
Plumbers can ensure the job meets plumbing code, which dictates everything from the type of pipe to the distance from fixtures.
Plumbers work more efficiently than DIYers and can complete the job with minimal damage and disruptions.
DIY plumbing work may void your homeowners insurance or manufacturer warranties.
Pro plumbers carry insurance and may offer warranties for their work.
Be prepared to describe your plumbing issues in detail so your plumber can accurately diagnose the problem.
A professional will need to know your plumbing setup, including the number of bathrooms and fixtures, as well as their locations.
Ask how long your plumbing will be out of commission until the vent pipe is replaced.

Positive experience. As previously stated, the replacement/repair could not be completed (no fault of the plumbing tech) b/c misinformation was rec?d by property management maintenance. Thanks to the plumbing tech for your efforts. Appreciate you!
If you want to pay the most exorbitant prices possible for your job, this is the company for you. “By the job” pricing is a rip-off, at least how these people use it. Every job is plugged into a category and prices are set by category. You might have a job that takes half an hour or one that...
Cole has been handling plumbing and general contracting for our four properties over the past three years, and he’s always done a great job. Most recently, he installed a sink and countertop in our retail store where none existed before, and it turned out exactly how we needed. He’s...
Matt is a consummate professional. The work turned out to be far more difficult than expected and rather than turn the job down, Matt rose to the occasion and completed a near impossible task. I can not recommend Greene's Plumbing Service more highly. On a scale of 1-5 I would give Matt a...

The initial quoted price from a walk-through seemed high, but we discussed that the quote represented worst case scenario (re-wiring to two floors) and we were excited about the opportunity to have the work done in a timely manner with closing for fire safety reasons, etc. When the job was...
Initially, I called the Service People to have a leaking garbage disposal replaced. I had purchased a special deal through Angie's List: $79 for $200-worth of plumbing services. <br /> When I went to schedule the work, the earliest date I could get through Angie's List was after the upcoming...
This company did a very good job on the brick wall and it looks just amazing. The staff was always professional and was practically OCD on how the bricks were stacked and how they were laid. Although it took longer than expected, I am willing to sacrifice time over perfection anyday. The...
<p>I am so glad we called Rotor-Rooter. I was hesitant to call them because we usually prefer to give business to local providers. But when we had sewage back up in our basement on a Saturday evening, I had a hard time getting a hold of someone, not to mention the high weekend/evening rate...
