Toilet Flange Repair
A Solid Base for Your Toilet
Toilet rocking, bolts spinning loose or a seal that keeps failing? Our plumbers repair or replace broken, corroded and low toilet flanges so your toilet sits solid and stays sealed.
Toilet Flange Repair for Broken, Corroded and Misaligned Flanges
The toilet flange is the round fitting at the top of the drain pipe where your toilet sits. It does two jobs: it anchors the toilet to the floor with closet bolts, and it provides the sealing surface for the wax ring or foam seal. When a flange cracks, corrodes or sits at the wrong height, the toilet can’t be held firmly or sealed reliably, no matter how many times the wax ring is replaced.
Flanges fail in several ways. Plastic flanges crack at the bolt slots when toilets rock or bolts are overtightened. Cast iron flanges in older homes corrode until the bolt slots break away. Metal rings on plastic flanges rust through. Flanges that were never screwed to the subfloor let the whole assembly shift. And flanges left below a newly raised tile floor create a gap the seal can’t bridge. We identify the exact problem before choosing a repair.

Why Flange Height Matters After New Flooring
A toilet flange is designed to sit on top of the finished floor, or very close to it. When a bathroom is remodeled with thicker tile, a mortar bed or new underlayment, the floor rises, but the flange often stays where it was. The result is a flange recessed below the floor surface. A standard wax ring may not compress enough to seal the gap, leading to leaks, odors and a toilet that rocks on its base.
Stacking two wax rings is a common shortcut, but it’s unreliable and can shift or collapse over time. Better solutions include flange extenders or spacer kits that raise the sealing surface to the correct height, or replacing the flange so it sits properly on the new floor. If you’re planning a bathroom floor project, it’s worth addressing the flange height while the toilet is already removed and the area is open.
Why Homeowners Trust Our Flange Repairs
A toilet is only as solid as its flange, so we don’t cover up damage with extra wax. Our licensed and insured plumbers inspect the flange, drain pipe and subfloor every time a toilet is removed. We choose a repair that restores a solid anchor and correct sealing height, secure the flange to the floor and reset the toilet with a new seal. You’ll know the toilet is firm and leak-free before we leave.

Benefits of Professional Toilet Flange Repair
Repairing a damaged flange stops your toilet from rocking and breaking its seal repeatedly. A secure, properly sealed toilet keeps wastewater and sewer gas from escaping into the bathroom or subfloor. Correct flange height ensures a reliable seal after new flooring. Catching subfloor rot early prevents larger structural repairs. And a firmly anchored toilet feels safer and more comfortable for everyone using it, including young children and older family members.

Signs Your Toilet Flange Is Damaged
Flange problems often show up as other issues first. Recognizing the signs early keeps a small repair from turning into floor damage.
A toilet that rocks even after the bolts are tightened often has a cracked or loose flange underneath. Bolts that spin without tightening, or pull up out of the floor, usually mean the bolt slots have broken. Repeated wax ring failures within a short time point to a flange problem rather than a bad seal.
Water or stains around the base, a soft or spongy floor near the toilet and sewer odors in the bathroom are all warning signs. Since the flange is hidden beneath the toilet, confirming the cause requires removing it, which also lets us check the subfloor.
How Our Toilet Flange Repair Works
Tell us whether the toilet rocks, leaks or keeps losing its seal. We’ll bring repair rings, inserts, extenders and replacement flanges.
Your plumber shuts off the water, removes the toilet and cleans away the old seal. The flange, drain pipe and surrounding subfloor are inspected. You’ll learn what’s damaged, the best repair method and the cost before we begin, including any subfloor repairs that might be needed.
The flange is repaired with a ring or insert, raised with an extender or replaced, then secured firmly to the subfloor. The toilet is reset with a new seal and properly tightened bolts. We test several flushes, check for leaks and confirm the toilet sits solid without rocking.

Toilet Flange Repair Questions Answered
Can a broken toilet flange be repaired?
Often, yes. Repair rings and inserts fix many cracked flanges. Severely damaged or corroded flanges may need to be fully replaced.
Why does my toilet rock after tightening?
The flange may be cracked or loose, or the floor may be uneven. Overtightening bolts can crack the toilet, so have it checked.
Should I use two wax rings?
It’s not recommended. Stacked rings can shift and leak. A flange extender or replacement provides a more reliable seal for low flanges.
Can you repair cast iron flanges?
Yes. We install repair rings or inserts where possible, or replace the corroded flange using fittings designed for cast iron drains.
How long does flange repair take?
Most flange repairs take one to two hours. Subfloor repairs or cast iron replacements can extend the time needed for the job.
