What Does It Cost to Replace Drain Pipes in a House?
The cost to replace drain pipes in a house typically falls between $225 and $1,169, with a national average around $696 for a standard single-room or partial replacement. Full whole-house drain pipe replacement can run significantly higher.
Here's a quick summary of what to expect in 2026:
| Project Scope | Typical Cost Range |
|---|---|
| Minor spot repair | $200 – $1,200 |
| Single room (kitchen or bathroom) | $100 – $500 |
| Basement or crawl space lines | $725 – $6,000 |
| Whole-house drain replacement | $6,000 – $15,000+ |
| Cost per linear foot | $150 – $250 |
These numbers shift depending on pipe material, location, labor rates, and how much of the system needs work. A simple fix under a kitchen sink is a very different job from replacing 50-year-old corroded cast iron throughout an entire home.
Drain pipe problems rarely announce themselves at a convenient time. One homeowner on a popular plumbing forum shared a quote of $12,000 to replace all the drain lines in a standard three-bedroom, two-bathroom house with 50-plus-year-old corroded pipes — and wanted to know if that number was reasonable. (Forum consensus put the fair range closer to $6,000–$10,000 depending on location and house size.) It's a good reminder that knowing the numbers before you call a plumber puts you in a much stronger position.
At All Pro Service Group, our team has been handling drain pipe replacements and plumbing repairs across the Greater Salt Lake Valley since 2008 — giving us a front-row seat to what the cost to replace drain pipes in a house looks like in the real world, not just on paper. In this guide, we'll walk you through everything you need to budget and plan your project with confidence.
Average Cost to Replace Drain Pipes in House in 2026
When calculating the overall budget for your home's drainage upgrade, it helps to look at both the broad national averages and the specific per-foot pricing. According to the Angi 2026 Cost Data, most homeowners pay between $150 and $250 per linear foot for professional drain pipe replacement.
If you are dealing with a localized issue, a single run of pipe might cost you slightly less. In fact, national data reveals that a standard installation for a single drain line run starts around $663 to $810. However, when those small leaks expand into a systemic failure, a whole-house repipe becomes necessary. For a typical 1,500 to 2,000 square foot home, a complete replacement of aging or failing drain pipes can run anywhere from $6,000 to over $15,000.
Below is a breakdown comparing average costs by project scope and pipe material before plumber markups:
| Project Scope / Material | Average Material Cost (Per Foot) | Average Total Installed Cost |
|---|---|---|
| PVC / ABS Plastic | $0.50 – $8.00 | $225 – $1,500 (Standard Run) |
| Cast Iron | $10.00 – $20.00 | $3,000 – $10,000 (Sewer/Main lines) |
| Copper | $2.00 – $10.00 | $1,500 – $8,000 (Branch lines) |
| Galvanized Steel | $3.00 – $8.00 | $2,000 – $9,000 (Older systems) |
| Whole-House Repipe (PEX/PVC) | N/A | $5,500 – $14,000+ |
Minor Repairs vs. Full Cost to Replace Drain Pipes in House
We always recommend using the "50% rule" when deciding whether to repair or replace your home's drainage lines. If the cost of a spot repair exceeds 50% of the cost of a full replacement, it is almost always more financially sound to replace the line.
Minor repairs, such as fixing a single leaking joint or patching a tiny crack, typically range from $100 to $800. Major repairs that require clearing root intrusions or replacing 10 to 15 feet of pipe can quickly climb to between $800 and $8,000. If you are constantly dealing with minor leaks, it is highly likely your pipes are reaching the end of their natural lifespan.
Understanding your material's life expectancy is key to making this decision:
- Galvanized Steel: 40 to 50 years (highly prone to internal rusting and narrowing).
- Cast Iron: 50 to 75 years (vulnerable to channel rotting along the bottom of the pipe).
- Copper: 70 to 80 years (can suffer from pinhole leaks due to acidic water).
- PVC / ABS: 75+ years (practically immune to corrosion, making them the modern standard).
If you suspect a hidden leak in your crawl space or behind your drywall, catching it early is vital. You can read our advice on detecting leaks in pipes to stop structural damage before it starts. If you find a minor drip, we also have a guide on the best way to stop a leaking pipe as a temporary measure while you wait for a professional team to arrive.
Room-by-Room Cost to Replace Drain Pipes in House
The room where your pipes are located plays a massive role in your final invoice. Accessibility is the name of the game here.
- Kitchen Drains ($100 – $500): Kitchen lines are usually easy to access under the sink or through an open basement ceiling. They carry grease, soap scum, and food waste, meaning they corrode faster than bathroom lines, but they are relatively cheap to swap out.
- Bathroom Plumbing ($100 – $10,500): A simple sink drain replacement is cheap, but replacing the drain lines for a toilet, shower, or bathtub can be incredibly expensive. This often requires cutting through drywall, removing tile, or even replacing the entire bathtub or shower unit, which can push costs past $10,000.
- Basement & Crawl Space Lines ($725 – $6,000): While crawl spaces offer open access, they are tight and difficult to work in. If your basement has finished ceilings or if the pipes are buried beneath a concrete slab, costs can easily skyrocket. Concrete slab cutting and repair alone can add $40 to $90 per square foot of affected area.

Key Factors That Determine Drain Replacement Pricing
Understanding the variables behind your plumbing estimate can prevent unpleasant surprises when the final bill arrives. Plumbers don't just pull numbers out of thin air; they look at material costs, accessibility, and local municipal requirements. To better understand how professionals track down the exact location of a broken drain line, you can reference the HomeAdvisor Drain Line Breakage Guide.
Pipe Material Costs and Lifespans
The material you choose affects both the upfront installation price and how long your home remains leak-free.
- PVC and ABS: These plastic pipes are incredibly durable, smooth, and easy to install. They cost between $0.50 and $8.00 per linear foot before plumber markup. Plumbers typically charge up to $7.50 to $14.00 per foot fully installed.
- Cast Iron: Still required by some strict local building codes for soundproofing (it is much quieter than plastic when water runs through it). It costs $10.00 to $20.00 per foot wholesale, but with a standard 25% to 50% plumber markup, expect to pay $12.50 to $30.00 per foot for materials alone.
- Copper: Highly durable but very expensive. Copper runs $2.00 to $10.00 per foot. If you are comparing systemic upgrades, you can use the House Repiping Cost Calculator 2026 | PEX vs Copper Cost to see how different materials scale across your home's square footage.

Labor, Permits, and Regional Cost Variations
Labor is the single largest cost driver in any plumbing project, accounting for roughly 60% to 70% of a residential repiping invoice. Standard hourly rates for a licensed plumber in 2026 range from $45 to $200 per hour.
Here in the Mountain West region—including Salt Lake City, South Jordan, West Jordan, Ogden, Provo, and Park City—labor rates run slightly higher than the national average, carrying a regional multiplier of 1.00 to 1.15x.
Local factors to keep in mind:
- Permits and Inspections: Standard residential plumbing permits cost between $100 and $500 depending on your city. For example, if you live in Ogden, you must comply with specific Sewer Utility Information | Ogden, UT guidelines.
- Local Labor Benchmarks: If you are shopping around in the West Valley area, you can search local directories like Top 10 Best Plumbers in West Jordan, UT | Angi to compare regional rates and find verified local professionals.
- Regional Project Costs: In areas like South Jordan, typical project costs can be reviewed via the Drain Repair in South Jordan, UT - Costs 04 / 2026 - Homeyou index. If you are high up in the mountains, winter weather and steep mountain access can also impact travel fees and overall project timelines.
Trenchless vs. Traditional Sewer and Drain Replacement
If your main drain line or sewer lateral is failing, you have two primary replacement paths: traditional open-trench excavation or modern trenchless technology.
Traditional excavation requires digging a physical trench along the entire path of your sewer line. While the actual PVC pipe material is cheap (about $300 for a 60-foot run), the labor, heavy machinery, and lawn restoration can easily drive costs from $3,000 to $20,000.
Trenchless methods allow us to fix or replace your underground pipes without destroying your yard, driveway, or patio. There are two main types of trenchless technology:
- CIPP (Cured-in-Place Pipe) Lining ($4,000 – $12,000): We insert an epoxy-saturated felt tube into your old pipe, inflate it, and let it cure. This creates a brand-new, jointless pipe inside your old one, reducing the diameter by just a quarter of an inch.
- Pipe Bursting ($4,000 – $15,000): We pull a heavy steel bursting head through your old pipe, breaking it apart while simultaneously pulling a new, highly durable HDPE pipe into place behind it.
To see which method is right for your home, review our detailed guide on trenchless sewer repair. If you are worried about the line running from your foundation to the municipal main, you can read about the cost to repipe the main sewer line to the street to budget accordingly. For a complete national cost comparison of these methods, look at the Sewer Line Replacement Cost 2026: $3,000-$25,000 Guide.
We also highly encourage homeowners to read our Ultimate Sewer Services Guide 2026 and the Sewer Services Salt Lake City Complete Guide to understand how local soil conditions and deep frost lines along the Wasatch Front affect underground pipe lifespans.
Frequently Asked Questions about Drain Replacement
How do I know if my home's drain pipes need to be replaced?
The most common warning signs include slow-draining sinks or tubs across multiple rooms, persistent sewer gas odors, frequent toilet clogs, and water stains on your walls or ceilings. If your home was built before 1970 and still has its original cast iron or galvanized steel lines, visual signs of rust, flaking, or a greenish buildup on copper lines are clear indicators of oxidation.
If you are experiencing constant clogs, we recommend starting with a professional sewer camera inspection. You can learn more about our local services on our Drain Cleaning in Salt Lake City and Plumbing Drain Cleaning pages to see how we pinpoint problems before recommending a full replacement.
Does replacing drain pipes increase my home's value?
Yes! While it isn't as visually exciting as a kitchen remodel, replacing old, failing drain pipes offers an average return on investment (ROI) of 50% to 70%. More importantly, updated plumbing provides prospective buyers with peace of mind and prevents major red flags on your home inspection report. Homes with modern PVC, ABS, or copper plumbing sell faster and are far less likely to suffer from sudden deal-breaking water damage during the closing process.
How long does a typical drain pipe replacement project take?
A localized, single-room drain replacement (such as a kitchen or bathroom sink line) usually takes between 2 to 5 hours. A complete, whole-house drain repipe typically takes 3 to 7 days, depending on the size of your home and how many walls we need to access. Trenchless sewer line replacements are incredibly fast, usually wrapping up in just 1 to 2 days compared to the 3 to 5 days required for traditional open-trench digging.
