How Much Does It Cost to Repair Your Pipes?

The costs for pipe repairs depend a lot on the condition of your pipes. If they are old, you are likely going to have to replace them.

Why are the average costs so high? With under-slab pipe repair or replacement, it is usually necessary to use trenching or tunneling in order to get to the pipes in the first place. Trenching is used to replace the lines from the perimeter of the building to the city’s main line. Tunneling is necessary in order to replace either sewer or water lines. Both of these processes can be complex and time-consuming.

Most plumbers charge you a specific amount per foot of pipes, which includes the materials and the pipes themselves. This can range from $40 per foot up to $250 per foot, depending on the type of pipes you have and the replacement products. If you do the work yourself, you should get a plumber to come in and make sure that it was done correctly. That being said, it’s better to trust a professional plumber to do the entire job so that it is done correctly from the very start.
