How Much Does Plumbing Cost for New Construction?

Building a new construction is a complicated endeavor that is compounded by the various elements that each individual task requires, such as the costs for plumbing a home. This is completely separate, the framing of a home or installing tile on floors, and is thus normally bid out separately.

When you’re planning on building a new construction, you’ll want to collect bids from a few different plumbers. Depending on the home’s location. The size of the building and the type of materials used are also some of the most important variables in construction expenses. Plumbing is not the place to go cheap. When things are built right, you can rest easy knowing your plumbing will stand up to daily use.

New Construction Costs:

How Big Is the Home?

Square or linear footage are the baselines for estimates. Prices vary from place to place and according to market fluctuations. The national average for a major plumbing project is about $4.50 per square foot of construction area.

In general, the larger the building the more expensive it is to plumb. Bigger buildings typically require more fixtures and pipes usually need to run farther. As you might expect, the more fixtures you need, the more you should budget for plumbing.

Where your location?

We have always mentioned that plumbing fees differ across states or areas and that’s a fact. Depending on where the new home or establishment will be built, the plumber fees entailed will vary.

Area and excavation equipment

Of course, If there are no nearby connections to the municipal water and sewer lines, then the land will need to be excavated to make way for those installations. Now, this isn’t as simple as using a shovel to dig the ground. With that said, you’ll have to set a budget on average, the cost ranges from $80 to $200 per yard of course, the rate depends on other factors as well.

Pipe Measurement & Supplies

In addition to square footage, the height of the space is another major factor and a costly one. diameter and length of the pipes that will be used for the construction. PVC pipe is apparently the cheapest option but know that the cost will still get bigger if the diameter of the pipe is bigger. Fittings also vary in terms of size and type. Ensure that you’ll seek the advice of a professional when making decisions to avoid plumbing problems in the future.

What Type of Materials Will You Use?

A plumbing contractor generally chooses the pipes and fittings for new plumbing. PEX and copper are the most commonly used materials for pipes.

PEX costs anywhere from $2,000 to $5,000 less to install versus traditional copper plumbing. The size and configuration of your home will greatly affect the final bill.

PEX is a flexible plastic tubing with many benefits:

  • It doesn’t leak or burst from freezing and is corrosion resistant.
  • It’s cheap and easy to install. A great option for replacing current pipes since it can be snaked through walls easily, requiring less holes.
  • It isn’t prone to corrosion.
  • It retains heat well, which conserves energy.

The only two cons are:

  • A short history of use. It hasn’t had time to prove its safety or longevity.
  • Though rare, rats and mice have been known to chew through it.

Chlorinated Polyvinyl Chloride (CPVC)

CPVC costs about the same as PEX at $0.50 to $1 per linear foot. It’s a rigid type of pipe used since the 1960s. It’s time-tested but eventually leaks or bursts completely due to lower-quality manufacturing processes, incorrect installation and improper fittings. When used correctly, it is a cheap alternative to copper piping and doesn’t corrode.

Repiping with Copper

Copper is the most expensive type of pipe to use at $2 to $5 per foot or anywhere between $5,000 to $20,000 for a full repipe. It is expensive and can burst when frozen. However, it is a safe metal that has stood the test of time as a water delivery system.

Replace Galvanized Pipes

Galvanized systems cost the same as any other type of pipe to replace. Some plumbers may encourage you to only replace visible piping in a galvanized system. Though they’re safe, they tend to corrode, creating clogs and lowering water pressure. Eventually they fail. Leaving any corroded pipes, including vertical ones, is a recipe for disaster because they can lead to water damage.

You may need to install new plumbing if your home has old, hazardous piping materials like:

Lead. This toxic metal can leach into your water causing serious health hazards.
Galvanized Steel. Though safe, it can rust from corrosion causing low water pressure.
Polybutylene. Used extensively from the 1970’s to the ’90s, these pipes are extremely fragile and easily broke.

If you don’t know down to the exact letter the ins and outs of plumbing from years of working in the industry, the actual measuring of footage is something best left to a professional, given the complexity of the task. For the best results, at least hire a consultant to help you with the complexities of measuring and estimating so that you can get it right the first time rather than finding out midway through the project that something critical was left out, such as adding vent pipes or figuring the wrong diameter for a drain pipe to a washing machine or dishwasher.
