Why neighbors call Lutz
We've been doing this in San Francisco since 1929. Over the decades we've learned that the best plumbing service has less to do with clever marketing and more to do with showing up on time, diagnosing honestly, and doing the work right the first time.
Every Tankless Boilers job we take on comes with our craftsmanship warranty, fully licensed technicians, and transparent pricing. If you've been burned by the industry before, we hope we'll be the company that restores your faith in it.

Common questions
How quickly can you get here?
We aim to dispatch within a few hours for emergencies across San Francisco, depending on crew availability. Scheduled service is usually available same-day or next-day.
Do you handle permits?
Yes. Every job that requires a permit is permitted by us, signed off by DBI or SFPUC as appropriate, and the paperwork is handed to you when we're done.
What's your warranty?
Craftsmanship is warrantied for one year. Most manufacturer warranties we'll handle on your behalf if an issue comes up.
