80521 and 80524 — Old Town and the west side
These two ZIPs carry the historic core of Fort Collins: the Old Town grid, the neighborhoods around Colorado State University, and the older housing running west toward the foothills.
This is where the late-1800s and early-1900s stock sits — original hardwood, plaster on lath in places, clay sewer laterals under mature street trees, and supply plumbing that ranges from fully updated to entirely original depending on the individual property. A very large share of it is student rental housing.
Spring Creek runs through the western and central part of this area, and the July 1997 flash flood remains the reference event for how quickly a stalled storm over that drainage escalates. The Cache la Poudre runs along the northern edge.
Winter break pipe bursts concentrate here more than anywhere else in the northern Front Range.
80525 and 80526 — central and south
The mid-century and later suburban core of the city. Housing here is largely 1960s through 1990s, with copper supply plumbing, cast iron or ABS drains, and full basements that were finished at some point after construction.
The failure profile shifts toward water heaters and appliances rather than pipes, which means losses are found faster and stay smaller, but they land on finished lower levels with carpet, pad and drywall to absorb them.
80528 and the southeast
Newer development running southeast toward Timnath and the I-25 corridor. Largely 1990s and later with modern plumbing throughout. 80553 is among the additional codes serving the area.
Flat ground with engineered subdivision drainage, which handles ordinary rainfall well and can be overwhelmed by the short intense downpours that northern Colorado summers produce. Sump pump failures during monsoon-season storms are the characteristic loss out here.

Frequently asked questions
Which Fort Collins ZIP codes do you cover?
80521, 80524, 80525, 80526 and 80528 cover the city, with 80553 among the additional codes serving the area. Loveland, Windsor and Timnath are generally workable depending on which contractors are available.
Which areas have the most winter pipe damage?
80521 and 80524, covering Old Town and the campus-adjacent neighborhoods. That is where the oldest housing and the highest concentration of student rentals overlap, and both factors point the same direction during winter break.
Is the newer southeast side lower risk?
For pipe failures, yes — modern supply plumbing fails far less often than century-old plumbing. For water damage overall, not really. Those homes have finished basements under laundries and bathrooms, so an appliance or water heater failure lands somewhere expensive.
