We Know Fort Collins Plumbing — All of It
Fort Collins isn't one kind of city. It never has been. There's a wide range of housing stock here — from Victorian-era homes in Old Town to brand-new builds out near Timberline. That matters for plumbing. Different eras of construction come with completely different pipe materials, layouts, and failure modes. In our experience, knowing the neighborhood before you walk in the door saves everyone time.
Old Town & Historic Neighborhoods
Old Town homes have character. They also have cast iron drain lines and galvanized water supply pipes that were installed decades ago — and are now showing their age. We're used to working in tight crawl spaces, around stone foundations, and under narrow lots where you don't always have room to maneuver.
Pre-1970s construction in neighborhoods like City Park and the streets surrounding downtown often means original galvanized lines. These corrode from the inside out. You'll start to notice lower water pressure, rust-colored water when a tap hasn't been used for a while, or mineral buildup at fixture connections. At some point, it's not a matter of if these lines need replacing — it's when.
Permit complexity is also higher in older areas. Historic districts have their own requirements. We know how to navigate Larimer County and City of Fort Collins permits without surprises.
Newer Developments
Fossil Lake Ranch, Stetson Creek, Rigden Farm — these neighborhoods were built more recently, and most of them use PEX or CPVC throughout. That's generally good news. These materials resist corrosion better than the old galvanized stuff. But they're not problem-free.
PEX fittings can develop slow leaks at connection points, especially in areas with temperature fluctuations — and Fort Collins winters are not gentle. CPVC can become brittle over time, particularly where it runs through uninsulated spaces. We've also seen installation shortcuts in some of the faster-built subdivisions from the mid-2000s that create issues years down the line.
Newer doesn't mean no maintenance. It just means different problems. We know what to look for in these builds and how to address them efficiently.

Fort Collins Is Our Hub — But We Go Further
We're based in Fort Collins, but our service area extends well beyond the city limits. Honestly, that's by design. A lot of the most interesting plumbing work in this region — septic systems, well pumps, rural infrastructure — happens outside the city.
If you're in Laporte, Wellington, or out in Red Feather Lakes, we've worked in your area. Same goes for Loveland, Windsor, Estes Park, Greeley, and Berthoud. Fort Collins may be the center of our coverage map, but it's not the edge of it.

Common Plumbing Issues We See in Fort Collins
Every city has its patterns. Here's what we run into most often in Fort Collins:
Cast Iron Drain Line Corrosion
Older homes — particularly those built before the 1970s — often have cast iron drain lines that have simply worn out. Cast iron is durable, but it doesn't last forever. Once it starts to corrode internally, you'll see recurring drain slowdowns, joint failures, and eventually breaks. In Old Town and City Park, this is a common conversation we have with homeowners.
Aging Water Mains
Some parts of Fort Collins have older water service lines — galvanized steel, older copper, or even lead in the oldest properties. These can fail slowly (pinhole leaks, pressure drops) or quickly (sudden bursts). If your home is more than 40 years old and the water main has never been looked at, it's worth having someone take a look.
Septic Systems on the City Fringe
Fort Collins has grown a lot over the decades. There are neighborhoods that were once well outside city limits — and built with septic systems — that have since been absorbed into or bordered by the city. Some of these properties are still on septic by choice or necessity. Aging septic infrastructure in these areas is something we deal with regularly.
Larimer County Permit Requirements
Plumbing work in Larimer County — and in the City of Fort Collins specifically — comes with permit requirements that not every contractor fully understands. Septic installations and repairs require Larimer County Health Department involvement. Water heater replacements typically need a permit. Major re-piping work does too. We pull the required permits on every job that needs one. This protects you when it comes time to sell or refinance.
Questions About Plumbing Service in Fort Collins
Do you serve all of Fort Collins?
Yes — all of it. From the historic streets of Old Town to the newer subdivisions out east near Timberline and Fossil Lake Ranch, we cover the whole city. We work in City Park, Rigden Farm, Collindale, Maple Hill, Stetson Creek, English Ranch, Observatory Village, and every neighborhood in between. If you're in Fort Collins, we can help.
How fast can you get to Fort Collins?
For planned work and non-urgent jobs, most customers get scheduled within the same week. For urgent situations — an active leak, a well pump that's completely stopped, a septic backup — we do our best to respond as quickly as we can. Call us and explain the situation honestly, and we'll tell you exactly what we can do. We won't string you along.
Do you handle both city-connected homes and septic systems in Fort Collins?
Yes, both. Fort Collins is a mixed environment — most homes in the city core are on municipal water and sewer, while properties on the outskirts and in the surrounding county use private wells and septic systems. We're fully comfortable working on either. We bring the same thoroughness to a city-water re-pipe as we do to a full septic replacement.

We serve Old Town, City Park, Rigden Farm, Fossil Lake Ranch, Timberline Area, Collindale, Maple Hill, Stetson Creek, English Ranch, and Observatory Village — plus every other part of Fort Collins. We also cover surrounding communities including Laporte, Wellington, Red Feather Lakes, Loveland, Windsor, Estes Park, Greeley, and Berthoud.
