Plumbing installed in our residential or commercial buildings tends to deteriorate over time. Due to age, they are prone to wear and tear. Some materials, such as PVC, copper, or wrought iron, can withstand the elements for 30 to 50 years if you do that. So, it might be the right time to do that if you have stayed in any place for more than a year and have not inspected or replaced the plumbing system.

It is primarily because the leaky, damaged pipes are a nuisance. If they are left unchecked and unrepaired, they cause detrimental problems. Anything from flooding, structural damage, or popping pipes during freezing weather can happen. This is when re-piping becomes necessary. But how much does it cost to repipe your house?

This blog will discuss factors affecting re-piping costs, piping material types, and a cost range that you should consider before restructuring the plumbing system. Moreover, we will also shed light on whether you should consider doing the replacement yourself or call a professional.


What Does Repining Involve?

Re-piping includes removing old pipe systems and replacing them with new ones. This will give your plumbing system an updated life expectancy for years. However, you might need to set a budget because it is a tedious and hefty investment. Let’s dive into how much does it cost to repipe your house.

Factors that Affect Repipe Costs

Before you know how much it costs to repipe your home, you need to understand that plumbers consider many variables when evaluating a plumbing project and determining its costs. Getting a quote from three or more licensed plumbers will help you better understand what you need for your specific home project.

Size of Home

The cost to repipe the house also depends on the size of the property. Larger houses often require more piping and longer work hours to produce a complete pipe.

Homes under 1,000 square feet are the most expensive, while homes over 3,000 square feet can see prices rise sharply. Rewiring an average 2,500-square-foot home can range from $15,000 to $25,000.

Number of Bathrooms and Water Fixtures

Each bathroom, kitchen sink, laundry tub, outdoor spigot, boiler connection, and other plumbing fixture must be connected to the new water delivery system during a repipe. Expect costs to increase incrementally for each additional fixture beyond the typical 2-3 fixtures in a standard home.

Type of Piping Material

Materials like copper piping and cross-linked polyethylene (PEX) are more expensive than polyvinyl chloride (PVC) or polybutylene pipes. Copper repiping may also require soldering skills and additional soldering supplies, which increase costs. PEX provides flexibility benefits but higher material pricing.

Location of Existing Pipes

Easily accessible basement or crawl space pipes lower labor costs, while externally buried lines or those tucked behind walls/ceilings require considerable extra time and invasiveness to access. External excavation can double repipe pricing.

Home Design and Floorplan

Open floor plans versus multi-story homes or those with finished wall/ceiling interiors provide varying degrees of access difficulty. Tight spaces significantly increase labor time.

Regional Labor Rates

Since labor accounts for 50-70% of total costs, pay rates for licensed plumbers in your specific city/state impact final pricing. Larger metropolitan areas generally have higher hourly costs.


Estimated Repipe Costs

While every home is different, here are some typical cost ranges you can expect for a complete residential repiping project depending on house size:

  1. Partial Repipe: Replacing sections of the plumbing system rather than a full tear-out can save money but generally runs $2,000-$10,000 depending on the linear feet replaced.
  2. Small Home (1,000 sqft): A full repipe for a small, single-story dwelling is estimated to be between $8,000 and $15,000 on average.
  3. Mid-Sized Home (2,000 sqft): For 2,000 square foot, 2-bath homes, budget $12,000-$25,000 for all new piping work.
  4. Large Home (3,000+ sqft): Larger 3,000+ square foot houses with 3+ bathrooms will likely be in the $15,000-$35,000 range.

Additional Cost Factors

  • Permits ($100-$400 depending on municipality)
  • Insulation for pipes in unheated areas (adds $500-$1,000)
  • New fixtures/ connections ($75-$150 each)
  • Oak wood flooring or tile removal & reinstallation (several thousand more)

It’s important to note that these figures serve as general guidelines only. Many unforeseen problems could be uncovered during the repipe process, increasing costs. The cost to repipe your house can be a worthwhile investment. To understand the expenses involved, request quotes from licensed plumbers and compare the estimates for repiping your home.

DIY vs Professional Installation

For some homeowners, tackling an entire home repipe can seem like an appealing money-saving option. However, there are several factors to consider carefully:

  • Potential savings of a DIY project vary widely based on skill level and experience with plumbing work. A professional repipe typically ranges from $10,000 to $30,000, while a DIY can save 30% or more if done correctly.
  • Plumbing work requires permits in most areas that an amateur may not obtain, risking code violations and inspection issues.
  • Proper sizing of pipe diameters, eliminating droops, and ensuring no joints leak over decades require expertise. Mistakes can be expensive to fix.
  • Working in tight spaces like attics and crawlspaces or cutting concrete/tile without proper protection is dangerous for amateurs.
  • Shutting off the main water line and safely draining pipes of residual water needs care. Flood damage from errors would defeat DIY savings.
  • Warranties from licensed plumbers protect against future leakage from faulty joints or material failures, and DIY work may not offer recourse.

Self-installation can be feasible for homeowners who are highly skilled at plumbing. However, for most, ensuring a job is done correctly by experienced professionals will provide long-term peace of mind and avoid potential repair costs. Hiring help for such complex work is usually recommended.

When a Repipe Becomes Necessary

Pipes will deteriorate steadily over decades with age and regular use. However, there are obvious signs a full repipe should be seriously considered:

  • Visible Corrosion: Thinning, rusty, or brittle pipes cannot deliver water pressure reliably and are at risk of bursting. Overly corroded pipes need replacement.
  • Water Leaks: Active leaks anywhere indicate weakened piping that will likely cause more significant leaks or floods if not addressed. One leak often means others will follow.
  • Low Water Pressure: Reduced flow from faucets/showers could mean restrictive mineral deposits, breaking joints, collapse, and narrowing pipe interiors over time.
  • Chronic Plumbing Issues: Repeated repairs like slipping valves, clogged aerators, and shut-off problems at shut-off valves point to old, faulty piping as the root cause.
  • Preventative Measure: A repipe provides fresher components for homes over 50 years old and prevents unexpected downtime from aging. It’s wiser than reactive fixes.
  • Burst Pipes: Frozen pipes that suddenly burst during winter are usually the last straw sign it’s time for all new plumbing before further, costly water damage occurs.


Repiping a home’s plumbing system is undoubtedly a significant undertaking and investment. However, for property owners of older homes showing clear signs of degraded piping, it provides renewed peace of mind against future leaks and system failures for decades.

With the proper budgeting and catching piping issues early before emergencies arise, repiping prevents expensive water damage risks. With new high-quality materials, a repipe renews a home’s entire plumbing infrastructure for reliability well into the coming decades.
