Leaks, pipes & freezing in Fort Collins, CO

Pipe problems range from a burst line that needs the water shut off right now to slow pinhole leaks that show up as a high water bill. A licensed plumber finds where the water is escaping, repairs or replaces that section, and tells you whether the rest of the piping is likely to follow.

Leaks, pipes & freezing services in Fort Collins

Local conditions

Leaks, pipes & freezing in Fort Collins: what's different

Northern Colorado winters bring long cold spells, and Fort Collins pipes freeze most often along exterior walls, in garages and in crawl spaces. Vacant units near campus over winter break are a classic case: the heat gets turned down and a line splits.

Older homes near Old Town can still have galvanized supply that restricts pressure, while 1970s–90s neighborhoods are reaching the age where copper develops pinhole leaks. Newer east-side homes use PEX, which tolerates freezing better but still fails at fittings.

Fort Collins housing and plumbing

Other Fort Collins conditions that affect plumbing

  • Clay soil movement: Expansive soils can shift slab floors and sewer lines, causing offset joints and cracks that show up on a camera inspection.
  • Rental-heavy wear near campus: Rentals near CSU see heavy use of toilets, disposals and drains, and frequent turnover means problems go unreported until they're bigger.
  • Cold winters: Northern Colorado winters bring long cold spells. Pipes along exterior walls, in garages and in crawl spaces freeze when heat is turned down in vacant units.

Leaks, pipes & freezing questions in Fort Collins

What temperature should I keep a vacant Fort Collins rental at in winter?

Keep the heat at least in the mid-50s °F, open cabinet doors on exterior walls, and shut off and drain outdoor faucets. During long cold spells, check on the unit or shut off the water.

Should I turn off the water if a pipe bursts?

Yes. Close the main shutoff valve first, then open a faucet on the lowest floor to drain the lines. If water is near outlets or the electrical panel, keep clear and switch off power only if you can reach the panel safely.
