What customers say

★★★★★

Sewer backed up into the basement at 11pm on a Saturday. They picked up, showed up in under an hour, and had it cleared and camera-inspected before 1am. Flat price like they said.

Water heater died in January. Straightline had a new one installed by 3 the same afternoon and hauled the old one away. Great communication the whole time.

Third plumber we called for a slow kitchen drain, first one that actually fixed it. Hydro jetting made a huge difference and they showed us the video.
