What neighbors say
Rated 5 stars across North County
5.0 average rating
Swift Flow replaced our water heater the same day we called. Clean install, upfront price, and they walked us through the whole thing.
Kitchen line backed up on a Sunday night. They answered, showed up, and cleared it fast without trying to upsell us on anything.
Repiped two bathrooms for our rental. Communication was constant, work passed inspection first try. Easily the most professional plumber we've used.
