The cost to redo plumbing is fairly high when you compare it to other household maintenance costs. However, in many cases, this job is necessary to undertake in order to prevent plumbing disasters. For instance, the pipes in your house are vulnerable to decay, rust, and corrosion, which can lead to leaks. This can potentially inundate your house with water or raw sewage and destroy your home and belongings.
Here is a complete guide on the cost to redo plumbing in a house.
Factors That Influence the Cost to Redo Plumbing in Your House
The cost to redo plumbing in your house depends on the factors listed below:
1. The Size of Your Home and the Extensiveness of the Project
The cost to redo plumbing in your home is directly proportional to the extensiveness of the project. This means that the cost to redo plumbing in an entire structure will be significantly higher than minor fixes.
Additionally, the size of your home will also greatly impact your cost. So, if you have a larger house, you will have to pay more for a plumbing project. A plumbing job in a house with more than one-story can also result in increased costs.
2. Replumbing vs. New Build
The cost of plumbing a new build will be quite different from the cost of replumbing a house. It typically costs less to install similar plumbing material of the same length in a new build than to replumb a house. Replumbing usually involves obstacles like insulation and drywall which cost more in terms of time, effort, and money.
3. Accessibility of the Plumbing
The most accessible plumbing is the one behind the walls and it typically requires fewer hours of work. So, your cost to redo plumbing will be less if your faulty plumbing is situated right behind your walls. Contrarily, your cost to redo plumbing will be higher if it is in inaccessible areas like closets and crawl spaces.
4. Number of Plumbing Fixtures That Needs Replacement
In a lot of cases, the cost to redo plumbing depends on the number of faulty plumbing fixtures. Here is a list of common plumbing fixtures found in homes
- Water heaters
- Washing machines.
Thus, your overall cost to redo plumbing will increase if you have a lot of damaged plumbing fixtures. This is because the plumber will have to replace the incoming lines and secondary drain separately for each fixture. Moreover, replacing the pipes for multiple plumbing fixtures needs more pipe and labor which adds to the cost.
5. Size and Type of Pipe You Use
This is one of the most important factors that influence your cost associated with your plumbing project. Generally, your costs will rise if you use a pipe with a large diameter. This might not seem too much for an individual fixture, however it can contribute to a major cost difference over the entire project.
The type of pipe you use also impacts your cost to redo plumbing in your house. Here is a list of options you have regarding the type of pipe
- Galvanized steel
PEX is the cheapest of all these available options.
6. Labor Costs
You will have to hire a plumber to replumb your house, which will increase your cost. Remember, the more complex the project, the more the cost is going to be.
Note – A low price from a plumbing contractor could indicate that the quality of their work is not up to the mark.
7. Local Permit Fees
Some states such as Florida require you to get a permit before taking up a major plumbing job. This can further increase your cost to redo the plumbing.
