Toilet Pull, Flange Repair & Reset: We safely pull the toilet, rebuild damaged flange collars, install heavy-duty reinforced wax seals, and anchor solid.
Chronic Running & Tank Leakage
Constant hissing water fills the overflow pipe, running up hundreds of dollars in water bills annually.
Complete Internal Rebuild: We replace worn flappers, install high-flow anti-siphon fill valves, replace tank-to-bowl gaskets, and calibrate water levels.
Severe Trap & Branch Line Clogs

help_outline Who Do I Call for a Running or Leaking Toilet in Fort Collins?
Call Star Plumbing Co. at (970) 499-0516 for fast, dependable toilet repairs throughout Fort Collins and Northern Colorado. A running toilet can silently waste up to 200 gallons of water per day, causing substantial spikes in your utility bills. Our technicians carry flappers, fill valves, flush canisters, and wax rings to fix your toilet quickly in a single service visit.
help_outline Should I Repair My Toilet or Replace It with a New Model?
If the toilet has a simple mechanical issue like a worn flapper, broken fill valve, or loose handle, a repair is quick and inexpensive. However, if the porcelain is cracked, the bowl constantly clogs due to outdated low-efficiency flushing channels, or the unit is over 20 years old, upgrading to a modern WaterSense-certified toilet delivers superior flushing power and lower water bills. We help you choose the best option for your budget.
help_outline Why Is Water Leaking Around the Base of My Toilet?
Water seeping around the toilet base typically means the wax seal underneath has degraded or the toilet closet bolts have loosened, allowing wastewater to escape each time the toilet flushes. Leaving this unaddressed can rot your bathroom subfloor and damage the ceiling below. A licensed plumber must pull the toilet, inspect the flange for cracks, and install a fresh heavy-duty seal to protect your home.

Toilet Repair & Installation FAQs — Fort Collins, CO
How much does toilet repair cost in Fort Collins?
It depends on what's wrong. A flapper or fill valve replacement is a relatively quick, low-cost repair. A toilet that rocks due to a failed wax ring involves more labor. A cracked tank or bowl that needs full replacement depends on the fixture you choose. We provide free written estimates — you'll know the price before we start.
My toilet runs constantly — does it need to be replaced?
Usually not. A constantly running toilet is almost always a flapper, fill valve, or float adjustment issue — all repairable parts. We assess what's causing the running first and repair it. Replacement is only the recommendation when the toilet itself has a structural issue like a cracked tank or bowl.
Can you install a toilet I already purchased?
Yes. We install customer-supplied toilets. Just let us know what you have when you call so we can confirm the rough-in distance and any fitting considerations before we arrive.
How do I know if my toilet has a wax ring problem?
Signs of a failed wax ring include water pooling at the base of the toilet (especially after flushing), a toilet that rocks or shifts, sewer odor in the bathroom, or soft flooring around the toilet base. If you're seeing any of these, have it inspected promptly to protect your subfloor.
