Copper or PEX

Both pass code and we install both. Copper is rigid and everybody knows it. PEX bends, so there are fewer joints in the wall and less drywall has to come out. Which one is right depends on your house and how the existing lines are laid out.

Questions people ask

When is it time to repipe a house?

Rusty water at the tap, pressure that drops hard when someone else turns on a faucet, and pinhole leaks that keep showing up in different rooms. One leak is a repair. The third one this year in a different room is the house telling you something.

Should I repipe with copper or PEX?

Both pass code and we install both. Copper is rigid and everybody knows it. PEX bends, so there are fewer joints in the wall and less drywall has to come out. Which one is right depends on your house and how the existing lines run.

Will you have to open my walls?

Some, yes. The quote includes the wall openings up front, and we patch the drywall we opened. With PEX, less of it usually has to come out.

Is a whole house repipe inspected?

Yes. The new lines are pressure tested and inspected before we patch the walls.
