Frequently Asked Questions

What types of leaks can you locate?

We are a leak detection plumber cpapable of finding slab leaks, underground water line leaks, gas leaks, radiant heating leaks, and many other hidden plumbing leaks.

Will you need to open my walls or floors?

The goal of our gas and plumbing leak detection company is to accurately pinpoint the leak before any demolition begins by using precise video leak detection equipment. Once the source has been confirmed, we’ll explain what access is needed for the gas or water leak repair.

Can you repair the leak after finding it?

Yes. After identifying the source of the leak, our licensed plumbers can recommend and plumbing leak repair, slab leak repair, or gas leak repair.

Do you work on older and custom homes in Tiburon?

Yes. Our water and gas leak detection services regularly perform work on a wide variety of homes throughout Tiburon and understand the unique plumbing systems often found in established and custom-built properties.

What should I do if I smell natural gas?

Leave the area immediately, avoid creating sparks or flames, and contact your gas utility. Once the area has been made safe, we can inspect your gas piping. Having a professional install gas leak detectors can help prevent future emergencies.

Do you have experience with Eichler homes?

Yes. Our team has extensive experience diagnosing plumbing and radiant heating systems in Eichler homes throughout Marin County. We can perform slab leak detection services, which can help identify hidden water leak under concrete slab, a common problem that can arise.

Why is my water bill suddenly so high if I don’t see a leak?

If you’ve noticed a spike in your water bill, this could be the sign of a hidden leak. Irrigation systems, an underground pipe leak, and toilet flappers can be common places for silent leaks.

Can you locate a water leak under concrete without digging?

Yes! We can use devices like thermal imaging leak detection cameras and acoustic listening devices to find leaks beneath concrete slabs.

What equipment do professional leak detection companies use?

Thermal imaging cameras can locate underground leaks, while acoustic listening devices are used to pick up sounds of otherwise silent leaks that humans can’t detect. We also employ the FAST Aqua M300 that uses acoustic sound, tracer gas leak detection, and pipe location to find leaks.
