• Toilets that rock or wobble due to improper flange height or subfloor issues

• Cracked porcelain in the tank or bowl

We service all brands including Kohler, Toto, American Standard, Delta, Gerber, Glacier Bay, Moen and Mansfield.

Professional Toilet Installation & Replacement

A toilet installation may look simple, but a correct installation requires proper alignment, sealing, bolt tension, flange height evaluation and supply line integrity. A poor installation leads to leaks, odors, wobbles and long-term subfloor damage.

DFW Plumber installs all toilet types, including:

• Standard two-piece toilets
• One-piece toilets
• Comfort-height (ADA compliant) toilets
• Elongated and round-bowl models
• Duel-flush and ultra high-efficiency toilets
• Low-profile modern toilets
• Wall-mounted toilets (rare but growing in popularity)

If your home is undergoing a remodel or upgrading fixtures, we ensure your new toilet fits your plumbing layout and is installed to meet code.

Clogged Toilet Diagnosis & Clearing

Clogged toilets are among the most common service calls we receive. But not all clogs are equal. Some are caused by simple buildup, while others come from deeper sewer or vent-line problems.

• Augering to break up toilet trapway blockages
• Deeper drain snaking for bathroom branch line clogs
• Main sewer clearing when multiple fixtures back up
• Toilet removal for toys, brushes or foreign items stuck in the trap

If your toilet overflows when you shower or use other drains, the real issue is a sewer line clog, not the toilet itself.

Toilet Leak Detection & Base Repairs

Leaks at the base of a toilet can go unnoticed until flooring becomes soft or begins to discolor. Common leak sources include:

• Failed wax rings
• Loose closet bolts
• Damaged or improperly installed flanges
• Cracked bowls

We correct flange height, replace damaged components, and reset the toilet to create a proper watertight seal.

Toilet Flange Repair & Subfloor Issues

A toilet that wobbles or shifts usually indicates a flange or subfloor issue. DFW Plumber repairs:

• Broken toilet flanges
• Flanges that sit too low or too high
• Rotted or water-damaged subflooring
• Incorrect spacing or alignment

Correcting flange height prevents future leaks and extends the life of the installation.

Toilet Upgrade Options

Many DFW homeowners upgrade their toilets during bathroom renovations or after recurring flushing issues. Popular upgrades include:

• Water-saving dual-flush models
• Comfort-height toilets for improved accessibility
• Pressure-assisted flush toilets for high-performance bathrooms
• Quiet-flush modern units
• Touchless or sensor-activated toilets

Newer toilets use significantly less water while often improving flushing performance.

Common Reasons Toilets Fail

Toilets can fail for various reasons, often related to age, installation or part failure. The most frequent causes include:

• Worn-out flappers causing constant running
• Damaged fill valves causing loud or weak refilling
• Mineral buildup clogging jets and reducing flush power
• P-trap obstructions stuck inside porcelain
• Improper installation causing rocking and leaks
• Cracks in porcelain leading to slow seepage

Early repair prevents bigger issues while extending the lifespan of the fixture.

Frequently Asked Questions

Why does my toilet clog so often?

Frequent clogs usually indicate a partial blockage in the trapway, a low-flow toilet with poor performance, or a deeper issue in the bathroom branch line or sewer line.

Why is my toilet running constantly?

A worn flapper, bad fill valve or failing overflow assembly is usually the cause. These inexpensive parts can waste hundreds of gallons per day.

Is it better to repair or replace an old toilet?

If the toilet is old, inefficient or has recurring issues, replacement is often more cost-effective. New toilets use less water and flush more efficiently.

Why is my toilet leaking at the base?

Base leaks are often caused by a failed wax ring or improper flange height. Leaving it untreated can cause severe subfloor damage.

What if I hear gurgling noises?

Gurgling usually means a venting issue or a partially blocked sewer line—not a toilet problem.

Can you install a toilet I purchased?

Yes. We install all customer-provided toilets and ensure they meet local code.

Do you fix wobbly toilets?

Absolutely. Wobbling usually indicates flange or bolt issues. We secure the toilet properly and fix any underlying structural problems.
