Plumbing costs depend on your project and location. Check with a local pro for your specific job.
The cost to repipe a house in Seattle trends above national averages because of elevated labor rates, permitting requirements, and higher operating expenses.
Copper piping is the most expensive option at around $3 to $9 per linear foot, while PEX and CPVC start at around $1 per linear foot.
Permit fees, drywall repairs, mold remediation, and water damage restoration can significantly increase your budget.
Hiring a licensed plumber in Seattle, WA, helps ensure code compliance and reduces risks of leaks, water damage, and failed inspections.
Seattle’s higher labor costs and elevated cost of living push repiping prices above the national average. The average cost to repipe a house in Seattle ranges between $1,667 and $16,665, with most homeowners paying around $8,333, depending on factors like pipe material, home layout, and project complexity. Here’s what to expect when budgeting for a repiping project in Seattle.
These are the main factors that will impact the cost to repipe a house in Seattle, WA.
Large homes have more plumbing fixtures and require longer runs for pipes and drain lines, so they cost more to repipe. Additionally, multistory homes cost more to repipe than single-story homes because you'll need more piping material to reach plumbing fixtures between floors.
There are three main types of plumbing pipe materials: copper, CPVC, and PEX. Costs vary with the material. For instance, copper ranges from around $3 to $9 per linear foot, while CPVC costs around $1 to $2 per linear foot.
Remember that local codes can dictate the types of pipes you can use. Your plumber can recommend the best material for your home.
| Piping Material | Average Cost Range per Linear Foot |
|---|---|
| PEX | $1–$3 |
| CPVC | $1–$2 |
| Copper | $3–$9 |
Proper piping is required for all of your home's fixtures, including toilets, sinks, and showers. The more fixtures you have, the more piping you'll need. Rough-in plumbing for a bathroom is costly, as getting pipes to precise locations is more labor-intensive than running plumbing behind walls. If you’re changing your home’s layout, expect to pay more for the total cost.
| Plumbing Fixture | Average Cost Range |
|---|---|
| Sink | $390–$890 |
| Dishwasher | $445–$890 |
| Washing machine | $390–$1,670 |
| Shower | $670–$1,780 |
| Water heater | $780–$2,000 |
The size, or diameter, of your pipes also affects costs. Pipes used for waste drainage are wider than pipes designed to carry water. For the same type of piping, larger diameters will be more expensive. However, most drain lines consist of PVC, which is less expensive than copper, so drainpipes should still be more affordable than water supply lines.
If your pipes are in a difficult-to-reach location, expect to pay more for repiping your house. For example, pipes under concrete are more difficult to access than pipes behind drywall, so they cost significantly more to remove and replace.
If your municipality requires a permit for repiping, you’ll need an inspection after the work is done to ensure everything is up to code. In most cases, the initial inspection cost is included in the permit fee. However, reinspection costs around $30 to $165 if an issue requires it.
The soil around your home can also affect the cost of repiping. For example, clay soil shifts over time, affecting the surrounding plumbing and leading to more costly installations. This is only a factor if you replace buried lines, like water mains, underground pool lines, and sprinkler lines.
Hiring a professional plumber is essential for this project to ensure everything is installed properly and up to code. These are the factors that impact the labor costs on your final bill.
Plumbers across the U.S. charge between $45 and $200 per hour. Plumbers in Seattle, WA, typically charge from $50 to $225 per hour because of the city’s elevated labor costs and high cost of living.
In most cases, you’ll need a permit from the Seattle Department of Construction & Inspections before repiping your home, unless your project falls below the $6,000 limit. Before work starts, confirm whether permit and inspection costs are included in your plumber’s estimate.
The materials used for your home repiping project are subject to Seattle’s sales tax rate of 10.55%. This will typically be accounted for in your estimate.
Along with a professional plumber, you may need to hire additional contractors to open and repair walls, ceilings, or flooring after the new piping is installed. Also, if there’s water damage or mold, you might need to bring in a water damage restoration or mold remediation specialist.
Here are some common professionals involved in repiping projects and their typical costs:
Water damage repair specialist cost: $1,380–$6,380
Drywall repair contractor cost: $300–$930
Ceiling repair contractor cost: $440–$1,730
Mold remediation specialist cost: $1,220–$3,760
Flooring repair contractor cost: $500–$3,000
General contractor cos: $50–$150 per hour
The ROI of repiping a house won’t likely show up as a higher selling price on the Seattle market, but it can still play a major role in protecting your resale value and helping your home sell faster.
While updated pipes aren’t always noted at first, worn or damaged pipes will often get flagged during home inspections, and this can give buyers leverage to negotiate concessions before closing, ultimately hurting your bottom line. With a modern and functional plumbing pipe system, you’re helping reassure buyers that the home is well-maintained, so you can stay firm on your price and close the deal with minimal issues.
To help homeowners plan their next project, Angi provides readers with carefully researched cost data and upholds strict editorial standards. We start with national average project costs, which we collect by analyzing competitor information, retailer material costs, and input from professional contractors. We then apply local price index data to calculate location-specific estimates that reflect what homeowners typically pay in their local area. To do that, we use data from the U.S. Bureau of Economic Analysis (BEA), including its Regional Price Parities (RPPs), which measure price differences across cities. This helps us account for differences in labor, materials, and overall cost of living, so estimates in higher- or lower-cost areas better reflect real-world local pricing.
Every estimate undergoes a thorough editorial review to verify accuracy, consistency, and alignment with observed market conditions.
