Cost Factors Of A Slab Leak Repair
The cost factors of a slab leak repair depend on the state of your current situation. For example, if your leak is easy to access, the price will be significantly less than a location that’s hard to access.
For an easily accessible slab leak, you can expect to pay about $630. On the other hand, for a complicated location, you may be looking at a price tag of about $4,400 or more.
|Cost Range to Repair a Slab Leak|
|Easily Accessible||National Average||Complicated Access|
There are a variety of other factors that affect the cost as well, such as:
- Leak Detection Costs
- Plumbing Repair Costs
- Any other issues that arise while fixing the leak
- Whether you should hire a contractor or do it yourself
There are a lot more variables that come into the price of this job. We will go through each to ensure you accurately estimate the cost of your slab leak repairs.
The Cost Of Hiring A Contractor To Check For A Slab Leak
The first thing you’ll need to do is check to see if your slab leaks. The best course of action is to hire a professional so they can:
- Tell you if you have a leak.
- Explain where the leak is occurring
- Quote you a price of repair
- Inform you of any additional actions that you need to take
The cost to detect a slab leak on average is $280. However, there is a low-end and high-end price. Your quote highly depends on the person that you hire. Each professional will have different rates that they charge.
The price will ultimately range from around $155 to about $400.
|Cost to Detect a Slab Leak|
A professional will look around your property for signs of a slab leak. Often, if you do have one, you can see the water seeping in through the cracks and seams in your foundation. Although sometimes, it’s not easily detectable.
This step may seem like it’s unnecessary; however, if you do not take care of a leak, it will cause significant damage. An undetected leak can cause your home to become unstable, not to mention the damage to the house as well.
Plumbing Repair Costs
The cause of your slab leak issue is a plumbing problem. When a pipe bursts under the slab, it needs to be repaired as soon as possible.
The price depends on two things:
- How severe is your leak?
- In what location is the leak?
If your issue is not severe and it’s easily accessible, you will pay around $500 to $1,100. Now, if it’s severe, and the location is not easily accessible, you are looking at $3,000 to $5,000.
The price is higher than the standard plumbing repairs because the pipes are under the slab. It takes a significant amount of working hours, and tools to break through the slab to the pipeline.
Other Potential Under-Slab Repair Costs
There are many variations as to what can be wrong with your under-slab issues. In this section, we will take you through the possibilities of problems.
The Cost Of Rerouting Your Under-slab Plumbing
If the pipes under your slab have rotted, you will need to have your plumbing rerouted. Unless you have a background in plumbing, this is not a DIY project. Any mistakes can put you and your loved ones in danger.
The cost to reroute your plumbing for small pipes costs between $200 and $500. However, if the larger pipes are the ones that need to be rerouted, then that will cost around $1,250 to $1,500.
Rerouting can be expensive, although it’s necessary to prevent further damage to your home and your land. If you do not fix the issue now, the damages can end up costing you over $30,000. Not to mention, it will cost you your home as well.
The Cost To Fix A Broken Pipe
This is the best-case scenario you could have! A simple broken pipe will run you around $150 to $350. The job is relatively easy, so that you won’t have a crew at your home for several days.
Keep in mind that this is on a per-pipe basis. For instance, if you have two large broken pipes, the cost will be around $700.
How Much Is It To Fix A Broken Water Line?
This circumstance is a bit trickier. The price that you will pay to fix a broken water line will dramatically vary.
For an average water main repair, it will cost around $840. Although, when it comes to water mains, this pricing quote is not a one-size-fits-all.
Again depending on the severity of the issue, it will cost between $150 to $3,000. However, most individuals will find themselves paying between $345 and $1,400.
How much you will pay depends on the amount of damage. Some of the lines may need to be repaired, while other areas may just need resealing.
The Cost Of Repairing The Slab
Finally, you have the cost of repairing the slab. Since your foundation is an essential part of your home, you must have this fixed.
If the professional gets in there and decides that you need your entire foundation replaced, that will cost between $3,500 and $7,000.
Since plumbers have to break your foundation to get to the leak, you will have to pay for that repair. Usually, it will cost between $1,900 to $4,000. However, you should note that this cost can be as high as $7,000 in extreme cases.
It is important to note that these estimates do not include the cost of repairing pipes or rerouting. Now, if the crack is tiny and it doesn’t affect the structure of your home, it will cost between $200 and $900.
|Cost Factors for Under-slab Work|
|Repair Factor||Price Range||Average Cost|
|Rerouting Plumbing||$200 – $1,500||$850.00|
|Fix a Broken Pipe||$150 – $700 per pipe||$350.00|
|Fix a Broken Water Main||$150 – $3,000||$840.00|
|Slab Repair||$200 – $7,000||$1,900 – $4,000|
|Extreme Damage Repair||$20,000 – $35,000|
As you can see in the table above, even the most extreme repair will be cheaper than repairing the damage to your home. Over time, your foundation will no longer be stable. Once the water rises, it will start to flood your house and threaten the stability of your home.
Instead of paying $20,000 to $35,000 because you were worried about spending $13,000– pay the $13,000! Your under-slab repair costs most likely won’t be that much. On average, you’re looking at $5,000 to $7,000 in total.
Hiring A Professional vs. Doing It Yourself
This is very important. Usually, as DIY advocates, we would typically explain how you can do a project on your own. However, considering this job includes breaking into your home’s foundation, it is not as safe to do on your own.
Now, if you’re an experienced plumber, or have the proper training, then, by all means, do it!
But, because this requires specialized equipment and the necessary knowledge, it is not ideal to do this on your own. There are some things, however, that you can do, such as looking for signs of a slab leak.
What If You Don’t Get The Slab Leak Repaired?
If you don’t get the slab leak repaired, a small issue will eventually turn into a large one. While it might seem daunting to have to pay over $2,000 to fix a slab leak, if you don’t fix it, you’ll find yourself paying over $20,000. You will sustain water damage, and eventually, your home may be deemed ‘unlivable’. Furthermore, you may be responsible for the costs to fix, as well as the costs to find another house to live in while it’s being fixed.
Something else you could do is sell the home as-is and hope someone has the money to buy it and fix it while you buy a new one. So yes, $2,000 is a lot of money, however, $20,000 to over $100,000 is a lot more.
How serious is a slab leak?
A slab leak is severe. It will cause severe damage to your home and foundation if left unattended. Over an extended period, your foundation will begin to shift and crack. Eventually, the shifting will lead to collapsing.
It is best to fix it now before you lose your home, and you are still left with the repair costs.
How do plumbers detect slab leaks?
Plumbers have specialized tools that they use to listen for leaks under your home’s foundation. They can use ground microphones to hear through the thick concrete.
Also, plumbers will be able to pinpoint the area of the leak using the ground microphone. Depending on the area where they find the leak, they can quote you the price to fix it.
How long does it take to repair a slab leak?
It takes about two days to repair a slab leak. However, if the professional needs to open up the foundation then it will take longer. But, more often than not it will only be about two days, depending on the finishing touches.
Fix Your Leak Before It’s too Late
The first course of action is going to be you saying, “Yes. I need to fix this.” While the damage may not be visible to you or anyone else, it will be when it is too late. Remember, the longer you wait to repair your slab leak, the more expensive it is going to cost. Do not risk your home, or in extreme circumstances, your life. We cannot stress enough how important it is to take immediate action.
Be sure to research companies and their prices. Sometimes, they will offer discounts if the job that needs to be done is tremendous or complicated. Your home should be a safe space! Never take this project on yourself, as slab leaks are serious and need to be corrected the right way.
