Common Toilet Problems We Fix
If you’re noticing water waste, odors, or a toilet that won’t flush reliably, it’s usually a repairable issue—especially when addressed early.
Running Toilet
Constant refilling can spike your water bill. We’ll pinpoint whether it’s the flapper, fill valve, chain, or overflow setting.
Recurring Clogs
Frequent clogs can signal a partial blockage, poor flush performance, or a venting issue. We’ll clear it safely and explain why it happened.
Weak Flush
Mineral buildup, worn components, or tank-to-bowl issues can reduce flushing power. We restore performance without guesswork.
Leaks at Base or Tank
Water around the toilet can damage flooring fast. We check the wax ring, bolts, gaskets, and supply line connections.
Rocking Toilet
A loose or uneven toilet can break the wax seal and cause hidden leaks. We stabilize it and address the underlying mounting or flange issue.
Slow Refill / No Refill
Low tank refill can be caused by a failing fill valve, clogged supply, or shutoff problems. We restore proper water flow and reliability.
What Our Toilet Repair Service Includes
We focus on durable fixes—no temporary patches—so you can stop worrying about leaks and repeat clogs.
Flapper & Fill Valve Replacement
Fix running toilets, phantom flushes, and inconsistent tank levels with properly sized, correctly adjusted parts.
Wax Ring & Seal Repairs
If water is pooling at the base, we’ll inspect the seal and reset the toilet as needed to prevent floor damage.
Closet Flange & Mounting Fixes
We address loose toilets and flange problems that can lead to recurring leaks and instability.
Supply Line & Shutoff Valve Help
We correct drips, corrosion, and worn connections to reduce the risk of sudden leaks.
Repair vs. Replace: What We’ll Recommend
We’ll walk you through options and costs so you can make a confident decision—especially if your toilet is older or has recurring issues.
Repair is often best when…
- It’s a single component failure (flapper, fill valve, gasket)
- The bowl and tank are in good condition (no cracks)
- The toilet is stable and the flange is sound
- You want the fastest, most cost-effective fix
Replacement may be smarter when…
- There are repeated clogs or persistent weak flush performance
- The porcelain is cracked or the toilet is heavily worn
- You’re upgrading for water savings and comfort height
- You’re remodeling and want a new look
Installation options: Standard height, comfort height, and efficient models. If you already purchased a toilet, we can install it and verify proper sealing and stability.
Toilet Repair FAQ
Quick answers to common questions we hear from homeowners and property managers in San Francisco.
Do you offer same-day toilet repair?
When scheduling allows, yes. Call +1 650-583-4522 and we’ll confirm the next available window.
What affects the price of a toilet repair?
Pricing typically depends on the cause (simple internal parts vs. resetting the toilet), access/condition of the flange and shutoff, and whether parts need replacement.
Can you replace a toilet I already bought?
Yes. We’ll inspect the rough-in, flange condition, and supply connection, then install and test for leaks and stability.
Why does my toilet keep clogging?
Common causes include partial blockages, low-flow/weak flush toilets, buildup in the trapway, or main drain issues. If plunging doesn’t solve it, we can diagnose and clear it safely.
