Star Plumbing Co. LLC is a locally based plumbing company serving every corner of Fort Collins — from the Victorian-era homes of Old Town with their aging cast iron drains, to the newer PEX-plumbed subdivisions in Fossil Lake Ranch and Observatory Village. We handle everything from a dripping faucet to a full sewer lateral replacement, and we treat every job with the same honesty and craftsmanship. Fort Collins is home — and we work here every day.
Yellow or brown stains on ceilings and walls usually mean a pipe is leaking above. In older Fort Collins homes, galvanized supply pipes corrode from the inside and can weep for months before a visible stain appears.
If pressure has gradually dropped in every fixture, mineral scale from Fort Collins hard water may be narrowing the insides of your supply pipes. This is especially common in homes built before 1980 with galvanized steel lines.
A single slow drain is often a local clog. When multiple drains back up at once — or when the same drain keeps clogging after you clear it — there's typically a bigger problem in the main line, often root intrusion in older neighborhoods.
Fort Collins hard water deposits sediment in water heater tanks, insulating the heating element and causing units to work harder. If you're running out of hot water faster than usual or hearing rumbling from the tank, it's time for service.
A sulfur or sewage smell near drains, in crawl spaces, or in your yard often means a sewer line issue. Old Town clay tile lines crack and separate over decades, and tree roots from mature elms and cottonwoods are a constant threat.
An unexplained jump in your monthly water bill often points to a running toilet, a hidden pipe leak, or a failed irrigation system backflow preventer. We locate and fix the source — not just the symptom.
Tank and tankless water heater service for all brands. We flush sediment, replace anode rods worn by Fort Collins mineral-rich water, repair heating elements, and handle full replacements with City permit and inspection.

Learn MoreFort Collins isn't a one-size-fits-all plumbing market. The city spans nearly a century of construction, from Old Town homes built in the 1880s with original cast iron drain stacks and galvanized supply lines, to neighborhoods like Rigden Farm and Stetson Creek developed in the 2000s with PEX tubing and CPVC. Each era comes with its own failure patterns, material quirks, and repair strategies. A plumber who only works on new construction will miss what's happening in a 1920s Craftsman on Remington Street — and vice versa.
Water quality is a factor that affects every home in Fort Collins, regardless of age. The city sources its water from the Cache la Poudre River watershed, which carries naturally high levels of calcium and magnesium. That mineral load deposits inside water heater tanks, builds scale inside pipes and faucet aerators, and degrades fixture valves faster than in soft-water cities. We account for hard water effects in everything we do — recommending water softeners where appropriate, flushing heater sediment on a regular schedule, and using fittings rated for high-mineral environments.
Permitting is another area where local knowledge matters. Work inside Fort Collins city limits requires permits through the City of Fort Collins Building Services. Properties on the rural edge — out toward Laporte, Bellvue, or along County Road 38E — may fall under Larimer County jurisdiction for septic and well work, which involves the County Health Department. CSU-area rental properties often have deferred maintenance histories, and we're experienced at navigating landlord-tenant repair situations with clear written documentation. Whatever your situation, we handle the paperwork so you don't have to.
"Our water heater died on a Thursday. Star Plumbing had someone out Friday morning, gave us a written estimate before touching anything, and had a new unit installed and permitted by early afternoon. Honest, fast, and fair priced."
"I manage rental properties near CSU and have dealt with a lot of plumbers over the years. Star Plumbing is the only one I call now. They show up when they say they will, explain what they found, and don't upsell work that isn't needed."
"We have a well and a septic system out west of town. Not many plumbers will touch that kind of work, but Star Plumbing came out, diagnosed our pressure tank issue, and fixed it the same week. Great to find a company that actually knows well systems."
Reach us by phone at (970) 672-3282 or through our contact form. Tell us what you're seeing — we'll ask a few quick questions to understand the scope before we schedule.
A licensed plumber visits your Fort Collins home, inspects the problem firsthand, and gives you a clear explanation of what's happening and why. No guesswork, no surprise scope creep.
Before we touch anything, you get a written estimate with itemized costs. We explain the options — including any trade-offs between repair and replacement — and let you make the call.
We complete the work to code, pull required permits through City of Fort Collins or Larimer County as needed, and handle all required inspections. You're protected from day one.
We walk you through the completed work, answer any questions, and make sure everything is running correctly before we leave. You'll have documentation of what was done and any warranty terms.
Yes. Properties in Fort Collins proper connect to the city sewer system, while homes on the rural edges — especially north and west toward Laporte and Bellvue — often have private septic systems. We're experienced with both and know which permits are required for each situation: City of Fort Collins Building Services for sewer work, Larimer County Health Department for septic.
Homes from that era in Fort Collins typically have galvanized steel supply pipes, which corrode from the inside out over 50–70 years. You may notice reduced water pressure, discolored water (especially when first turning on a tap after a period of non-use), or pinhole leaks. Cast iron drain pipes from that period are also common and can crack or corrode at joints. A plumbing inspection can give you a clear picture of where things stand.
Yes. The City of Fort Collins requires a permit for water heater replacement, and the work must be inspected by a city building inspector. We handle permit applications and coordinate inspections as part of every water heater job we do — this is included in our estimate, not an add-on.
Fort Collins water is moderately to highly hard due to mineral content from the Poudre River watershed. Over time, calcium and magnesium deposits build up inside water heater tanks, hot water supply lines, and fixture valves. This reduces flow, stresses the water heater's heating element, shortens the life of appliances like dishwashers and washing machines, and causes fill valves and flappers to fail more frequently. A whole-house water softener or a dedicated softener on the water heater inlet can significantly extend the life of your plumbing system.
Absolutely. We work with both individual landlords and property management companies on CSU-area rentals regularly. Rental homes near campus often have deferred maintenance histories and high-traffic wear on fixtures like toilets, faucets, and garbage disposals. We provide detailed written reports of work completed — useful for your maintenance records and any security deposit documentation.
