Toilet Problems That Mean It's Time to Call a Plumber
Not every toilet issue is a quick fix. Some problems point to worn-out parts, failed seals, or damage that gets worse if ignored. If you notice any of the following, it's time to call a professional:
- Water around the base — Could be a failed wax ring, a cracked bowl, or condensation buildup
- Rocks or shifts when you sit down — The flange may be broken, or the bolts have corroded
- Constant running or phantom refills — Usually a flapper or fill valve issue, but sometimes a sign of internal cracks
- Weak or incomplete flushes — Mineral buildup, blocked rim jets, or a failing flush valve
And these are just as important to watch for:
- Frequent clogs — If plunging is a weekly event, something deeper is going on
- Water leaking from the tank, supply line, or shut-off valve — Even slow drips cause damage over time
- Hairline cracks in the tank or bowl — These only get worse and can lead to a sudden failure
- Loose or broken handle — Often a quick fix, but sometimes part of a larger internal problem
- Toilet won't flush at all — Could be a disconnected chain, a blocked trapway, or a failed internal mechanism
How Hidden Toilet Leaks Turn Into Floor Damage
A toilet can leak for weeks — sometimes months — before you notice visible damage. By that point, the subfloor may already be soft, warped, or starting to rot. Here's what we commonly find:
- Broken wax seal — Water seeps out with every flush, running underneath the toilet and into the subfloor
- Flange too high or too low — A flange that doesn't sit flush with the finished floor throws off the seal
- Water coming from somewhere else entirely — Sometimes what looks like a toilet leak is actually a supply line, shut-off valve, or tank condensation issue
- Slow subfloor damage — The floor feels spongy near the toilet, tiles are cracking, or you notice a musty smell — all signs of long-term water exposure
If you're seeing any of these signs, it's worth having a plumber take a look before a small leak turns into a much bigger problem. Our team can identify the source of the leak and recommend the best course of action.
Need help with a major toilet problem?
Sometimes the issue goes beyond the toilet itself. If sludge, grease, or tree roots have worked their way into the sewer line, that backup is going to hit the lowest drain first — and that's usually a toilet. We see this more often than you'd think. If your toilet is bubbling, draining slowly, or backing up regularly, the problem may be in the main line, not the fixture. Our drain cleaning services can clear the blockage and get things flowing again.

Professional Toilet Installation
A new toilet should be installed correctly from the start. Poor installation leads to leaks, rocking, and early failure — problems we fix regularly for homeowners who tried going the DIY route or hired someone who cut corners. Here's what a proper installation includes:
- Removing the old toilet and inspecting the area beneath it
- Inspecting the flange and floor for damage, rot, or improper height
- Installing the correct seal — wax ring or wax-free gasket, depending on the setup
- Checking the supply line and shut-off valve — replacing them if worn or corroded
- Testing flush performance and checking for leaks before we leave
- Cleaning up completely — we leave the bathroom the way we found it
Looking to install a high efficiency unit?
If you're replacing an older toilet, it's worth considering a high-efficiency model. Dual-flush toilets and EPA WaterSense-certified units use significantly less water per flush without sacrificing performance. We can help you choose the right model for your home and handle the full installation.
You're Not a Toilet Expert. You Shouldn't Have to Be.
There's a lot of bad advice floating around online. Here are some of the myths we hear most often — and what's actually going on:
"If there's water at the base, it's always the wax ring."
Not necessarily. It could be condensation, a cracked tank, or a leaking supply line. We check every possibility before replacing anything.
"Just tighten the bolts if the toilet rocks."
Over-tightening can crack the porcelain. If a toilet is rocking, the flange or floor beneath it usually needs attention.
"If it clogs a lot, you need a stronger toilet."
Frequent clogs are often caused by partial blockages in the drain line, not the toilet itself. A new toilet won't fix a blocked pipe.
"It's running? Just jiggle the handle."
That might work once, but a running toilet usually means the flapper, fill valve, or overflow tube needs to be replaced.
"Toilet installation is easy — just set it and caulk it."
There's a lot more to it. A bad installation leads to leaks, sewer gas, and a toilet that shifts over time. It needs to be set on a properly positioned flange with the right seal and hardware.

Toilet Repair & Installation FAQs Answered by Our Toilet Plumbers
My toilet is leaking at the base. Is that always a wax ring problem?
Not always. A wax ring failure is one of the most common causes, but water at the base can also come from a cracked bowl, a loose supply line connection, tank condensation, or even a leaking shut-off valve. We check every potential source before recommending a fix.
Why are my pipes "dry" but the floor keeps getting wet around the toilet?
This is more common than people realize. A few things can cause it:
- Slow tank leak — A hairline crack or failed gasket between the tank and bowl can release small amounts of water during or after flushing
- Tiny base seep during flushing — The wax seal may be partially compromised, only leaking under pressure
- Heavy condensation — In humid weather, cold water in the tank causes moisture to form on the outside and drip down to the floor
My toilet keeps randomly refilling in the middle of the night. What's that?
That's called "phantom flushing" or "ghost flushing." It usually means the flapper at the bottom of the tank isn't sealing properly, so water slowly leaks into the bowl until the fill valve kicks on to refill the tank. It wastes water and can run up your bill. In most cases, replacing the flapper or the entire flush valve assembly solves the problem.
Why does my toilet clog all the time?
Frequent clogs usually come down to one of three things:
- Weak flush mechanics — Older toilets or low-flow models may not generate enough force to clear the trapway consistently
- Partial blockage deeper in the drain line — Buildup, roots, or debris in the pipe slows drainage just enough to cause recurring problems
- Venting issues — If the vent stack is blocked (leaves, debris, bird nests), air can't flow properly and the flush loses suction
When should I stop repairing and just replace the toilet?
If you're calling a plumber more than once or twice a year for the same toilet, or if the porcelain is cracked, the flange is damaged, or the toilet predates the 1.6-gallon federal standard (pre-1994), it's usually more cost-effective to replace it. A new, properly installed toilet will save water, flush better, and give you years of trouble-free use.
How long does toilet installation usually take?
A standard toilet replacement — removing the old unit, inspecting the flange and floor, and installing the new toilet — typically takes about one to two hours. If we find flange damage, subfloor issues, or supply line problems, it may take a bit longer.
