Common Toilet Problems We Solve
Toilets are complex fixtures with several interconnected parts. When one component fails, it can lead to a variety of issues. Our technicians are experts at diagnosing the root cause of the problem and implementing the right fix.

Running Toilets
Is your toilet constantly running, sounding like it's flushing intermittently or always refilling the tank? This common problem wastes a significant amount of water, driving up your utility bills. The cause is usually related to a faulty flapper valve that isn't sealing properly, an incorrectly adjusted fill valve, or a worn-out flush valve. We can quickly identify the component causing the issue and replace it, stopping the water waste.
Leaky Toilets
Toilet leaks aren't always obvious. You might see water pooling around the base, notice a steady drip from the tank, or hear water running continuously. Leaks can originate from various points, including the tank-to-bowl connection, the wax ring seal at the base, or even cracks in the tank or bowl itself. Our Leak Detection + Repair expertise allows us to find the source of the leak, whether it's visible or hidden, and perform the necessary Plumbing Services to seal it, preventing potential water damage and mold growth.
Clogged Toilets
A clogged toilet is one of the most common and frustrating plumbing emergencies. While a plunger can often clear minor blockages, stubborn clogs require professional tools and techniques. Foreign objects, excessive toilet paper, or issues deeper within the drain line can cause severe blockages. We utilize effective methods, including professional snaking and Drain Cleaning, to remove obstructions and restore proper drainage without damaging your pipes.
Weak or Incomplete Flushing
A toilet that doesn't flush completely can be embarrassing and inconvenient. This problem is often linked to issues with the flush valve, the fill valve, or mineral buildup in the rim jets. A weak flush might not clear waste effectively, leading to frequent clogs. We can adjust or replace the faulty components and clean buildup to ensure a powerful, efficient flush.
Wobbly Toilets
A toilet that rocks or wobbles when you sit on it indicates a problem with its installation. This can be caused by loose mounting bolts or an improperly seated base due to a damaged or old wax ring. A wobbly toilet is not only unstable but can also lead to leaks around the base, potentially damaging your floor. We can re-secure the toilet and replace the wax ring if necessary, ensuring it is stable and properly sealed.
Other Issues
From noisy flushing sounds and slow-filling tanks to toilets that don't flush at all, our technicians can troubleshoot and repair a wide range of other toilet-related problems.
Repair or Replace? We Help You Decide
When facing toilet issues, you might wonder if repair is sufficient or if it's time for a full replacement. This decision often depends on several factors, and our technicians can provide expert guidance based on your specific situation. Factors to consider include:
- Age of the Toilet: Older toilets (pre-1994) use significantly more water per flush (up to 3.5 gallons) than modern low-flow models (1.6 gallons or less). Replacing an old toilet can lead to substantial water savings over time.
- Frequency and Cost of Repairs: If you're constantly repairing the same toilet or the cost of a single repair is approaching half the cost of a new toilet, replacement might be the more economical long-term solution.
- Type of Problem: Cracks in the porcelain tank or bowl usually necessitate replacement, as these cannot be reliably repaired and pose a leak risk. Internal component issues are often repairable.
- Water Efficiency: Upgrading to a high-efficiency toilet (HET) or a low-flow model can drastically reduce water usage, saving you money and being environmentally friendly.
- Cosmetic Desires: Sometimes, a toilet replacement is part of a bathroom remodel or simply desired for a more modern look or comfort features (like comfort height).
Benefits of Repairing: Repair is often the faster and less expensive option for fixing isolated issues like a faulty flapper or fill valve.
Benefits of Replacing: Replacement offers the opportunity for a fresh start, eliminates recurring problems, improves water efficiency, and updates the look of your bathroom. It also provides peace of mind knowing you have a new fixture with a warranty.
When Replacement is Recommended: We typically recommend replacement for older, inefficient toilets, those with irreparable cracks, or toilets requiring frequent, costly repairs.

Understanding Toilet Service Costs
The cost of toilet repair or replacement in Castle Hills can vary depending on several factors.

Professional vs. DIY/Handyman
While some minor toilet issues might seem simple to fix yourself or can be attempted by a handyman, relying on a licensed plumber offers significant advantages, especially for persistent problems, leaks around the base, or replacement.
Plumbers have specialized tools, extensive training, and in-depth knowledge of complex plumbing systems and local codes. They can accurately diagnose problems that a handyman might overlook, ensuring the repair is done correctly the first time. For toilet replacement, a licensed plumber ensures the new toilet is installed properly, the wax ring creates a perfect seal, and the connection to the drain line is secure, preventing future leaks and costly damage. Attempting complex repairs or replacements without the right expertise can lead to further damage, more expensive repairs down the line, or even water damage to your home. Trusting a professional plumber provides peace of mind and a reliable, long-lasting solution.
