Repiping in Denver, CO

Is it time?

• A second or third pinhole leak in a short span
• Brown or orange water when a tap first opens
• Pressure that is weak at several fixtures, not just one
• Exposed pipe that looks crusted, flaking or green at the joints
• A plan to remodel a kitchen or bath with walls already open

Why older Denver homes come up

Denver's median home was built in 1975, and about 55.5% of housing went up before 1980. Houses from earlier decades can still have galvanized steel supply lines, which rust from the inside and narrow over time. Newer homes are less likely to need a full repipe, but a section can still wear out or be undersized for an addition.

Before work begins, it is worth asking about the line from the street. Denver Water says the owner owns the service line into the house, and its Lead Reduction Program replaces lead service lines with copper at no direct cost to the owner. Pairing the inside repipe with a plan for the service line avoids paying twice.

Materials compared

Denver Water uses chloramine as its disinfectant, which matters for filters and aquariums; ask the plumber about material choice for your house rather than relying on online claims.

What the job looks like

A typical repipe runs new lines from the main valve to each fixture, then the old pipe is capped or removed. Walls and ceilings are opened in small sections, so drywall patching follows. Many homes keep water on most nights while the work moves room by room. A basement with an open ceiling makes the job far simpler than a finished one.

Cost and permits

Price depends on the number of fixtures and floors, how much finished space must be opened, the material and who handles drywall repair. Ask the plumber which Denver Community Planning and Development permit the job needs and who will apply for it.
