Why tunnel?
Breaking through a finished floor means removing tile, wood or carpet and patching concrete. Tunneling from outside the house reaches the pipe from below, so the inside of your home stays in use.

Under-Slab Tunneling questions
Is tunneling better than breaking the floor?
It depends on where the break is and what’s on top of it. Tunneling keeps finished floors intact. Call to talk through your options.
Is my family able to stay home during the work?
Because the work happens outside and under the house, the inside of the home usually stays in use. Ask us about your job.
How much does tunneling cost?
It depends on the length of tunnel and the repair. Call (346) 244-6040 for an estimate.
