Repiping in Boulder, CO

Signs it is time

• Leaks that move from one room to another over a year or two
• Rust-colored water from older taps first thing in the morning
• Weak hot water at more than one fixture
• Patched drywall or plaster from earlier pipe repairs
• Threaded steel pipe or corroded copper visible in the basement

A single leak on otherwise sound pipe calls for a repair. Repeated failures across pipe of the same vintage usually mean the rest will follow.

Boulder conditions that matter

The City of Boulder runs its own water system, treating water at the Betasso and 63rd Street plants and disinfecting with chlorine rather than chloramine. The city also runs a corrosion control program aimed at reducing lead picked up from home plumbing. Its service line inventory found no lead service lines, and the city encourages owners of homes built before 1956 to verify their pipe material on its online service line map. That map covers the buried service line, not the copper or steel inside your walls.

City code makes customers responsible for upkeep of the area between their meter pit and the street, and only city staff may open meter pits. For an after-hours emergency that needs water turned off, the city asks customers to call 303-441-3200.

Boulder Planning and Development Services is clear on where repairs stop and new work begins: fixing a leak or swapping a toilet without moving pipes is exempt, but replacing concealed drain or supply piping needs a plumbing permit. A repipe falls in that second category.

Cost factors

• Size and number of bathrooms
• Construction: plaster walls in older homes take more care to open and patch than drywall
• Basement access, which shortens routing for the main runs
• PEX or copper
• Permit and inspection scheduling through the city

What happens after you call

You will be connected with an independent local plumber who works in Boulder. Mention the build year, what pipe you can see, and where leaks have shown up. The plumber looks at exposed lines and the water heater, then explains whether a section or the whole house makes sense and handles the single-trade plumbing permit with the city at 1101 Arapahoe Avenue.
