Frequently Asked Questions

How much does leak detection cost?

Leak detection cost will be made up of several factors, including pipe layout and accessability. We can only give an exact estimate once we come out to your property and have a look at the problem.

Do you repair the leak after you find it?

Yes, we can repair slab, water, and gas leaks after locating them with our equipment. We explain all of your repair options before beginning any work.

How does slab leak detection work?

Slab leak detection devices include thermal imaging, acoustic listening devices, and tracer gas to locate the hidden leak without having to perform any digging.

Do you offer gas leak detection in Sausalito?

We do! We can inspect gas piping as well as install gas leak sensors that can warn you of early signs of a gas leak.

What do I do if I suspect a leak but don’t know for sure?

If you are noticing signs like unexplained water damage, mold growth, or jumps in your water bill, it is best to have a leak detection professional come out and search for a hidden leak. Leaving possible leaks unchecked can lead to massive damage and wasted water.
