Why Star Plumbing
We believe the bar for plumbing companies is honestly pretty low. Most homeowners just want someone who shows up when they say they will, tells the truth about what's wrong, and doesn't make you feel like you're being taken for a ride. We try hard to be that company.
We tell you what's wrong, what it'll cost, and what happens if you wait. If the repair is a bad investment, we'll tell you that too.
We know Old Town's aging cast iron pipes and Fossil Lake Ranch's newer PEX systems. Local knowledge matters when diagnosing fast.
We give you a real two-hour arrival window. We call if something changes. Waiting all day for a plumber with no update — that's not us.
Everything goes in writing before a single tool comes out. What we quote is what you pay. No add-ons at the end of the job.
Septic to water heater to sewer main — we handle it all in-house. No handoffs to three different contractors for one property issue.
We specialize in homes. Our scheduling, pricing, and communication are built around homeowners — not commercial project managers.
Urgent Situations
Burst pipes, sewage backups, and active leaks can't wait. When an urgent line breaks or a basement floods, you need an experienced emergency plumber or on-demand 24 hour plumber. Unsure whether your issue is urgent? Read our guide on what counts as a plumbing emergency. Call us directly at (970) 499-0516 or visit our emergency plumbing page for what to do right now, response times, and what to expect when we arrive.
Emergency Plumbing Details →Our Process
We try to keep it simple and stress-free. Here's what typically happens from your first call to the finished job:
Tell us what's going on. We'll ask a few targeted questions so we come prepared with the right parts and tools — no charge for the call, no obligation.
We offer same-week scheduling for most jobs. You get a confirmed 2-hour arrival window — not "sometime between 8 and 5." We call the day before to confirm.
We perform on-site diagnostic testing, explain what we found in plain English, and hand you a written estimate before touching anything. You decide — zero pressure.
Once you approve, we perform the targeted repair or installation. We keep the area tidy, protect your floors and fixtures, and let you know if anything unexpected turns up — before adding costs.
We walk you through what was done, answer your questions, and make sure everything works before we pack up. You only pay what was quoted.
Local Plumbing Guides
We believe an informed homeowner makes better decisions. Browse our latest guides on maintaining your plumbing, well, and septic systems in Northern Colorado soils and weather conditions.
Before you call us for a well pump repair, check these three common electrical and pressure tank issues that you can safely rule out yourself.
Northern Colorado's clay-heavy soils and freeze-thaw cycles impact drain fields differently. Learn the true lifespan of a local septic system.
Store-bought liquid drain cleaners often damage older cast iron and PVC pipes without removing the actual clog. Here is what we recommend instead.
Specialty Services
In Larimer County, the permitting and soil conditions add complexity that not every plumber knows how to navigate. We do this regularly — site evaluation, county OWTS permits, new system installation, and targeted component repairs. Review our guide on Northern Colorado septic longevity.
Whether you're installing a new system, dealing with a drain field backing up, or replacing a tank at end of life, we walk you through the process step by step in plain English.
Septic System Services
When a well pump stops working, life gets uncomfortable fast. We diagnose most well pump issues on the first visit — check our well pump diagnostic guide. Within an hour we can tell you whether the pump needs to be pulled and replaced, or if it's a simpler fix like a pressure tank bladder or switch. We also provide our comprehensive private water & waste guide for rural property owners.
We'll give you the honest answer even if it means a smaller job for us. Submersible pump pulls require the right equipment — this one is worth calling a professional for. See the full scope of what we cover on our Well Pump Repair service page.
Well Pump ServicesLocal Coverage
We know Fort Collins well — and that's not just a line. Different parts of town genuinely have different plumbing challenges. Older homes in Old Town and City Park commonly have cast iron and galvanized steel lines that corrode from the inside out. Newer builds in Fossil Lake Ranch or Stetson Creek are mostly PEX and CPVC — totally different diagnostic approach. We know what to look for before we even walk in the door.
Not sure if we cover your neighborhood? Give us a quick call — or explore our recent local work portfolio to see projects near you.
A small leak behind a wall can rot framing, breed mold, and damage insulation — turning a $300 repair into a $3,000–$8,000 gut job over months. A septic that "seems fine but smells funny" can fail completely. A well pump that short-cycles eventually burns itself out. These are real calls we get from Fort Collins homeowners who waited.
The job doesn't get smaller on its own. It only gets bigger.
We're not the right fit for everyone. If you want someone to tell you everything is fine so you can put it off another month — call someone else. But if you want an honest answer about what's actually happening with your plumbing, what it'll cost to fix, and how urgent it really is — call us now.
Speak to a real plumber. No call center. No voicemail maze. Get a straight answer today.

What Customers Say
We work hard to earn good reviews — and we don't expect them until we've earned them. Here's the kind of feedback we get:
"Our septic system was backing up and I had no idea where to start. They came out within a day, walked me through what was happening, and gave me options at different price points. No pressure at all. We ended up doing a targeted septic repair instead of full replacement and it's been solid ever since. Honestly appreciated the honesty."
"Hot water heater gave out on a Thursday morning. They fit us in Friday, showed up exactly when they said, and had the new unit fully installed by early afternoon. Pricing was transparent and they explained everything about the new unit. Will definitely use them again — and already referred them to a neighbor."
"We're on a well out near Laporte and our pump was cycling every few minutes and losing pressure. They diagnosed it fast — turned out to be the pressure tank bladder, not the pump, which saved us a significant amount. Quick fix, fair price, and they explained exactly what to watch for going forward. Didn't try to upsell us on anything."
"I'd been smelling something odd in my basement for weeks and assumed it was nothing. Called Star Plumbing on a whim — turns out I had a cracked cleanout cap letting sewer gas into the house. Simple fix, but I wouldn't have found it on my own. They were in and out in under an hour and charged a fair rate. Highly recommend."

Here's Everything You Get When You Call Us
Most plumbing companies charge for an estimate. Show up late. Give you a vague number and pressure you on the spot. Here's what we do differently — and what you get every single time you call:
We come to you, diagnose the problem in person, and give you a written quote before any work begins.
What we quote is what you pay. No "we found some extra stuff" charges after the job. Price changes only happen with your explicit sign-off.
We don't give you an 8-hour window and disappear. You get a 2-hour slot and a call if anything changes. Your time matters.
We explain what's wrong in language you can actually understand — not jargon designed to make you feel like you have no choice but to approve everything.
Where it makes sense, we give you a repair option and a replacement option with honest pros and cons. You decide. We don't decide for you.
For jobs that need Larimer County permits, we handle the paperwork and scheduling. You don't have to navigate the county building department yourself.
Before we leave, we show you exactly what was done, test everything, and answer your questions. You're not left guessing whether it was done right.
If something we did isn't working right, we come back and make it right. This isn't a special warranty program. It's just what we do.
Everything above, on every single job. No asterisks. No fine print. No upsells you didn't ask for.
If we can't fix it, we'll tell you that before you pay us anything. If we don't know the answer, we'll say so and point you to someone who does. We'd rather lose a job than give you bad information. That's not marketing — it's just how we operate.
