How Much Does it Cost to Repipe a House with PEX?

The average cost to repipe a house is between $3,500 and $11,000. The average cost of the last 500 estimates generated by our Repipe Cost Calculator is $6,785. This is accurate as of June 11, 2024 and is subject to change as material costs increase or decrease from the time of writing this article.

· Size of the Home: As one might expect, the larger the home, the higher the cost. Larger properties require more material (such as more lineal feet of new piping) and are more labor intensive. A 2,200 square foot home may only require 10 drywall openings, while a 6,000 square foot home may require more than 30 drywall openings.

· Type of New Piping Material: While this article focuses on PEX – which is what we recommend to our clients – it’s important to recognize that different materials come with varying costs. Some clients prefer replacing their old piping with copper, which is considerably more expensive in terms of both materials and labor compared to PEX. For example: PEX is a flexible piping system, which allows it to be easily ‘fished’ through joist spaces without extensive drywall removal and repairs. On the flip side, copper piping is not flexible. This means installers are often required to create drywall openings large enough to fit the entire length of each pipe.

· Complexity of the New Installation: Most home repipe projects are straightforward, but some unique circumstances can affect labor and material costs. For instance: In a log home, our plumbers cannot route new PEX piping through the walls as cutting into log walls and repairing them effectively is impractical and almost impossible. In such cases, installers would need to find alternative routes for the PEX piping, which may increase the number of drywall or tile openings that need to be repaired.

· Location: Permitting costs for repiping projects can vary significantly depending on the property’s location. We strongly advise against and do not undertake any pipe replacement projects without obtaining the necessary permits. For example: In El Paso County, Colorado, condominium permitting fees are considerably higher than costs for similar projects in Pueblo County, Colorado. Some building departments have more stringent requirements, such as engineer-stamped building plans, varying amount of departments who are required to approve the permit, or fire rated panel retailed requirements – all of which can increase permitting costs. Counties that are more familiar with repiping needs and may have fewer requirements. Therefore permitting costs can vary based on the specific county building department’s regulations.

· Labor Costs: Professional labor charges are a significant part of the total cost to repipe a house with PEX, and this is where Replumb Specialties Inc. really shines. Many repipe companies use subcontractors for different parts of a project—one for plumbing, another for drywall repairs, and yet another for painting. This practice leads to multiple markups and higher costs for customers. Without naming specific companies, we can say that some with names very similar to Replumb Specialties Inc. follow this approach and charge property owners outrageous prices.

At Replumb Specialties Inc., we handle every part of the repiping project in-house – from permitting to plumbing to painting. This approach eliminates unnecessary markups from multiple contractors, keeping costs more reasonable for our clients. We encourage you to compare our prices with others to see the difference for yourself.
