Toilet Repair, Installation & Replacement in Paramount, CA
Running · Rocking · Clogged · Leaking, Fixed Right | Kohler, American Standard & Glacier Bay Installed | CSLB #1051553 | Se Habla Español
A toilet problem is never a mystery for long; it is always one of a short list of parts or one conversation about replacement, and the difference between the two is a proper look inside the tank and under the base. Ser Plumbing repairs the fixable ones by name (fill valve, flapper, flange, wax ring) and replaces the rest with models that fit your bathroom, your household, and California’s water rules.
What you will not get is the runaround: a running toilet is usually a modest repair, a rocking one is usually a flange conversation, and we will tell you which yours is before anything gets sold.

The Problem: Why People Call
Six symptoms cover almost every toilet call. Each one points somewhere different, and each one has a named part behind it.
What’s Covered
Toilet repair, with the part named
Fill valves, flappers, floats, flush valves, supply lines, angle stops, closet bolts, and wax rings. You hear which part failed and why before we touch it, and most repairs finish the same visit from truck stock.
Toilet replacement and new installation
Removal, haul-away, new wax seal or waxless gasket, new bolts, and a level, sealed set. We stock and install Kohler, American Standard, and Glacier Bay, in standard and comfort-height, round and elongated, and dual-flush where it fits the household. Cracked porcelain, hairline or otherwise, is the one symptom with no repair aisle: a cracked tank or bowl is a replacement conversation, full stop. Every new unit sold in California is a 1.28 GPF WaterSense-class design; the good ones flush better than the water-hogs they replace, and we will tell you which those are.
Flange repair and replacement
The section the old website never had. Broken plastic flanges, corroded cast iron, concrete-set flanges, and the repair rings, extenders, and full replacements each situation calls for, plus the subfloor conversation when rot has spread: what must be fixed now versus what can wait for the remodel.
Running and clogged toilet service
Diagnosis first: tank parts, bowl jets, or the drain beyond. If the problem is actually the line, you will know, and the drain team takes it from there. Drain cleaning →
Wall-hung and specialty toilets
In-wall carrier systems, wall-hung bowls, and bidet seats (a wildly popular upgrade lately) installed with the electrical and clearance realities explained up front.

Pricing
Toilet work is quoted from what we find, and here is where it typically lands:
What moves the number: the model you choose, what we find at the flange, supply line and angle stop condition, and disposal of the old unit. The written number comes before the work, and if the flange surprise appears mid-job, you see it and approve before anything changes.
Standard labor discounts apply, and free estimates cover replacements and new installations.
Why Ser Plumbing for Toilets
The part gets named
Fill valve, flapper, flange, wax ring: you hear exactly what failed and see it. Vague diagnoses are how small repairs become full replacements.
Flange competence
Anyone can bolt a toilet down. Fixing the corroded cast iron or concrete-set flange underneath it correctly is the actual skill, and it is why our installs do not rock.
Replace only when it earns it
A repair that buys years wins. When replacement genuinely makes sense (age, cracks, water usage), you get model options across three stocked brands and a straight recommendation.
Same-visit resolution
Common repair parts and popular replacement models ride on the truck, so the great majority of toilet calls end with a working bathroom, not a follow-up appointment.
Clean is non-negotiable
Toilet work has every opportunity to be gross. Drop cloths, gloves, haul-away, and a bathroom left cleaner than we found it; the reviews mention it constantly for a reason.

Leave Us a Google Review ↗Toilet FAQs
Fifteen straight answers to the questions we hear on the phone every week.
Ask us directly ↗My toilet keeps running. Is that an easy fix?
Why does my toilet rock back and forth?
Loose closet bolts, if you are lucky; a failing flange if you are not. Do not just caulk it down; rocking grinds the wax seal open and sends water under your flooring where it does quiet damage. It is a same-visit diagnosis.
How much does a toilet installation cost?
Typically, $250 to $950 all-in, driven by the model you choose, the condition of the flange underneath, and haul-away. The written number comes before the work, always.
Is it worth switching to a low-flow toilet?
If your current unit predates the mid-1990s, yes, without much debate: you are flushing three times the water per pull, and modern 1.28 GPF designs flush better than the old water-hogs, not worse. Utility rebate credits sometimes sweeten it further; we will tell you when one applies.
What is a comfort-height toilet, and should I get one?
A bowl two to three inches taller than standard, at chair height. For taller users, older knees, and multi-generational households, it is usually the single most appreciated bathroom upgrade we install, and every brand we stock offers it.
Why is there water around the base after flushing?
Most often, it's a failed wax ring, and the reason it failed matters: a rocking toilet or bad flange kills wax rings on repeat. We replace the seal and fix the cause, or you will be calling someone again next year.
