How Much Does It Cost to Repipe a House in Denver, CO? [2026 Data]

Denver’s higher cost of living pushes repiping costs above the national average. The average cost to repipe a house in Denver ranges between $1,587 and $15,870, with most homeowners paying around $7,935, depending on factors like home size, pipe material, and labor requirements. Here’s what to expect when budgeting for repiping in Denver.

House Repiping Cost Factors 

These are the main factors that will impact the cost to repipe a house in Denver, CO. 

Size

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.

Materials

There are three main types of plumbing pipe materials: copper, CPVC, and PEX. Costs vary with the material. For instance, copper ranges from $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.

Number of Plumbing Fixtures

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.

Diameter of Piping 

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.

Accessibility

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.

Inspection Cost

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 $25 to $160 if an issue requires it.

Soil Conditions

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.

Plumbing Pro Costs

Hiring a licensed plumber in Denver, CO, 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.

Local Labor Rates

Plumbers across the U.S. charge between $45 and $200 per hour. In Denver, plumbing labor costs generally range from $45 to $215 per hour due to rising construction demand and moderately higher living costs. 

Permits

Home repiping projects require a permit from the City and County of Denver. Before work starts, confirm whether permit and inspection costs are included in your plumber’s estimate.

Taxes

The materials used for your home repiping project are subject to Denver’s minimum tax rate of 9.15%. These costs will usually be built into your estimate.

Additional Pros to Consider Hiring 

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 cost: $50–$150 per hour 

Does Repiping a House Increase Home Value?

The ROI of repiping a house won’t likely show up as a higher selling price on the Denver market, but it can still play a major role in protecting your resale value and helping your home sell faster. 

Buyers looking at high-priced homes in Denver typically expect plumbing systems to be functional, and worn or damaged pipes can become a red flag on home inspection reports that ultimately hurts your bottom line. By replacing your pipes with a modern, functional system, you’re helping reassure buyers that the home is well-maintained, so you can stay firm on your asking price and sell quicker.

How Angi Gets Its Local Cost Data 

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.
