How Much Does It Cost To Replace Old Pipes In A Home?

Are you on the cusp of a plumbing catastrophe? Or are you just concerned it may happen sometime in the future?

Either way, in a 2-bathroom 1,500 sq ft house, replacing old pipes will set you back an average of $7,000 with costs ranging between $4,000 and $10,000. It requires the cutting open of floors and walls, so you do not want to undertake this before you need too. Here is how you can troubleshoot the status of your plumbing pipes and know when it is time to look for a replacement.

Plumbing Pipes Lifespan

The kind of plumbing you have in your home will determine its life expectancy. Take a look at your home inspection document you received when you made your house purchase and find out what type of pipes are installed in your home – or you can hire a local plumber to perform plumbing inspection.

Supply Lines Lifespan

  • Brass: 80-100 years.
  • Copper: 70-80 years.
  • Galvanized Steel: 80-100 years.

Drain Lines Lifespan

  • Cast iron: 80-100 years.
  • PVC (known as Polyvinyl chloride) 25-40 years.

Just because your pipes may be older it does not always mean they will need to get replaced. Pipes that have been well-maintained might last longer than ones that have been poorly maintained or in places containing hard water (this means the water has a high amount of mineral content) might fail sooner. Regardless of the age of your pipes, they are always worth focusing on to ensure they function correctly.

Remove Polybutylene and Lead

There are 2 kinds of plumbing pipes that need to be replaced immediately regardless of their age:

  • Lead pipes: They were used back in the 1900s and many have lasted over one hundred years but lead can be leached into drinking water, creating a health hazard!
  • Polybutylene pipes: They were used for nearly 30 years (1970s to the end of the 1990s) and are also very susceptible to breakage and should be replaced without delay.

Look For Symptoms Of Issues

When your home is in excess of sixty years old, look on an annual basis for pipe exposure in crawlspaces, utility rooms, and basements. Look at the tubing and see if there are stains, dimpling, discoloration, flaking or pimples, all of which are signs of corrosion. Hire a plumbing company to perform an inspection for you if you find this.

Keep an eye out for leaks as well. Small leaks can be easily repaired but may be a sign the need for a full replacement is close. Remember if they are the original pipes they have been subject to the exact same usage and water patterns for the lifetime of the house.

Similarly, view at the water’s color in the bathtub, especially after, (say) you have been on a vacation and the water has been pooling in the pipes for some time. If your water has yellow or brown, it is rust and a sign that the pipe is decaying on the inside.

Best Time for Pipe Replacement

You will need to hire an honest plumber to let you know if pipe replacement is needed. You really should get a 2nd and 3rd opinion prior to starting a project to replace the pipes, however, there are some ways you can lower the hassle and cost of the job.

Replace Pipes that are Exposed

Consider replacing the pipes that are not buried in walls or behind wood paneling or plaster walls. A fairly simple but larger job would be to replace pipes in a crawlspace, utility room or a basement because your plumber has easy access to the piping. If the configuration and design of your home allow, the plumber may be able to access most of your plumbing system in this manner. For a 1,500 sq ft home, you will pay an average of $4,000 with prices ranging from $2,000 to $6,000 or more just to replace the plumbing that has been exposed.

Replace Pipes When You Remodel

When you renovate a house, make an inspection and if needed, replace the plumbing lines that get exposed when you open up the walls and floors. Included in this is not only the pipes in the bedroom or the kitchen that you’re remodeling but also any pipes passing through any walls that feed the bathrooms upstairs. As the pipes are exposed because of the greater renovation project, the additional cost may only be $250 to around $1,000 – an absolute bargain considering you have eliminated a problem that is tough to reach when you had the initial opportunity.

PEX Limits Demolition

Your plumbing company might be able to lower the amount of wall demolition he would otherwise have to perform by using PEX piping in the form of a plastic hose style pipe to access and replace the inside-the-wall pipes. PEX can be sneaked into walls in a similar manner to the way electrical technicians feed wires behind plaster or wallboard – obviously this is not possible with rigid copper piping. PEX meets most building codes almost everywhere and with a twenty-five-year warranty and takes a small chunk of your budget than copper. To replace a 1,500 sq ft 2 bathroom home with copper piping averages around $9,000 with costs ranging from $8,000 to $10,000.
