Sink Repair in Las Vegas, NV
Leaking drain, slow draining sink, water pooling under the cabinet, or a garbage disposal that stopped working — Royalty Plumbing diagnoses and repairs sink problems and all kitchen plumbing issues across the Las Vegas Valley. We fix the actual problem, tell you honestly when replacement makes more sense, and clean up before we leave.
What Does Sink Repair Cost in Las Vegas?
Sink repair in Las Vegas typically costs between $100 and $350 depending on what component has failed and where the sink is located. A p-trap replacement — one of the most common sink repairs we perform — runs $100 to $175. Drain basket and strainer replacement runs $125 to $200. Supply line and shutoff valve replacement at the sink runs $100 to $175. Drain stopper mechanism repair runs $75 to $150. Garbage disposal repair runs $150 to $300 depending on whether the jam can be cleared or a component needs replacement. In Las Vegas, most sink repair failures trace directly back to hard water mineral buildup accelerating corrosion on drain components, p-traps, and supply connections — the repair is almost always fast and the part cost is low. We tell you the exact cost before we start.
The price depends on several factors:
- Which component has failed — p-trap, drain basket, supply line, stopper mechanism, or disposal
- Kitchen, bathroom, outdoor, garage, or utility sink location and access conditions
- Whether supply lines and shutoff valves need replacement alongside the drain repair
- Condition of the drain rough-in connection at the wall — corroded or damaged drain inlets add to the scope
- Whether the problem requires sink replacement rather than repair

Signs Your Sink Needs Professional Repair in Las Vegas
Las Vegas hard water at 280 to 290 PPM attacks sink components from two directions simultaneously — mineral scale builds up inside drain pipes and p-traps, reducing flow and eventually blocking it, while the same minerals accelerate external corrosion on metal drain baskets, p-trap fittings, and supply connections. These are the signs that a repair call is overdue:
- Water pooling inside the cabinet under the sink — the single most urgent sink symptom. Water under the sink means a slow leak has been occurring long enough to accumulate. Every day it is left, the cabinet floor absorbs more water and the risk of mold growth and structural damage increases. The source is almost always the p-trap, a supply line connection, the drain basket seal, or a garbage disposal connection
- Sink drains slowly — partial mineral blockage inside the p-trap or the short drain line between the basket and the p-trap. In Las Vegas, this almost always involves calcium and soap scum combining into a hard mineral deposit that restricts flow progressively. A slow drain that has been slow for more than a few weeks has a buildup that will not clear on its own
- Drain is completely stopped — a full blockage in the p-trap or the drain line behind the wall. If snaking the drain does not clear it, the blockage may be mineral-hardened enough to require p-trap removal and manual clearing
- Foul smell from the drain — a p-trap that has run dry (common on rarely used sinks in Las Vegas's dry desert climate) allows sewer gas to enter the home through the drain. Running water to refill the p-trap resolves it temporarily. A p-trap that keeps losing its seal has a slow drain or ventilation issue that needs professional assessment
- Visible corrosion or mineral crust on the p-trap or drain fittings — white, tan, or green mineral deposits on the exterior of drain fittings and p-traps are visual confirmation that the interior surfaces are scaling as well. A p-trap that is heavily mineral-encrusted on the outside has reduced interior diameter and is often already leaking at the slip joint connections
- Leak at the drain basket where it meets the sink basin — the seal between the drain strainer and the sink basin has failed. In Las Vegas, mineral deposits work their way under the putty or silicone seal over time, breaking the watertight connection. This causes water to leak directly through the sink basin into the cabinet below
- Drain stopper does not work properly — the lift-rod mechanism that operates the pop-up stopper on bathroom sinks corrodes and seizes in Las Vegas's hard water environment. A stopper that will not stay up or will not seal when closed has a failed or mineral-locked pivot rod mechanism — If the issue is at the faucet rather than the drain, see our faucet repair page.
- Garbage disposal leaking, humming without spinning, or completely dead — a humming disposal that does not spin has a jammed impeller plate. A leaking disposal has a failed gasket at the sink flange, a cracked housing, or a loose discharge connection. A disposal that does not respond at all has either a tripped reset button or a failed motor
How Royalty Plumbing Handles Sink Repair in Las Vegas
-
Step 1 — Assess and Locate the Problem
We open the cabinet, inspect every connection under the sink — p-trap, supply lines, drain basket seal, disposal connections, and shutoff valves — and identify exactly where the failure is. We check the drain flow while we are there to confirm whether the issue is isolated to a single component or whether there is a secondary problem contributing. In Las Vegas, what looks like a single leak is often multiple points failing simultaneously because the same hard water mineral damage affects all the components equally over the same period of time.
-
Step 2 — Honest Repair or Replace Assessment
We tell you what is wrong, what the repair costs, and whether the sink itself is worth repairing or whether replacement is the better financial decision. A sink with a failed p-trap on an otherwise sound basin is always worth repairing. A sink with a cracked basin, a permanently stained or pitted surface, and failing drain components is often better served by replacement — which we can schedule and complete at the same visit or a follow-up appointment.
-
Step 3 — Repair Performed
We replace the failed component — p-trap, drain basket and strainer, supply line, pop-up stopper mechanism, disposal gasket, or drain connection — using correct-specification parts for the sink type and plumbing configuration. For PVC p-traps and drain assemblies, we use schedule 40 rated fittings rather than the thin-wall ABS components that corrode faster in Las Vegas's hard water and chemical drain cleaner environment. We also inspect and report the condition of shutoff valves and supply lines while the water is off.
-
Step 4 — Flow Test and Cleanup
We restore water, run the sink, verify drain flow, check every connection under the cabinet for drips, confirm the garbage disposal operates correctly if it was involved in the repair, and clean up the workspace completely. You test it yourself before we leave. If anything is not right, we address it before we pack up.
The Most Common Sink Repairs We Perform in Las Vegas — and Why They Happen Here
Every sink repair on this list is more common in Las Vegas than in most U.S. cities. The reason is consistent: 280 to 290 PPM hard water accelerates every form of corrosion and mineral accumulation that causes these failures in your kitchen plumbing.
P-Trap Replacement
The p-trap is the curved pipe section under the sink
that holds a water seal to block sewer gas from entering the home. It is also the lowest point in the
under-sink drain assembly, which makes it the primary collection point for mineral scale, soap scum, and
debris. In Las Vegas, p-traps accumulate calcium deposits significantly faster than in soft-water markets —
and the exterior of the trap corrodes at the slip joint connections where Las Vegas mineral water repeatedly
wets and dries the fittings. A p-trap that is leaking at the slip joints, blocked with hardened mineral scale,
or visibly corroded needs replacement. We replace with schedule 40 PVC, which resists mineral interaction
better than the thin-wall chrome ABS traps common on older Las Vegas homes.
Best for: Slow or stopped drains that originate under the sink, leaking slip joint
connections, and any p-trap showing visible corrosion or mineral encrustation.
Typical cost: $100 to $175.
Drain Basket and Strainer Replacement
The drain basket — also called the
sink strainer — is the metal fitting that sits in the drain opening of the sink basin and connects to the
drain tailpiece below. The seal between the basket and the sink basin is made with plumber's putty or
silicone, which Las Vegas hard water deposits work under over time, breaking the watertight connection and
creating a leak that drips directly into the cabinet. A corroded, pitted, or loose drain basket that leaks at
the sink surface requires removal, cleaning of the sink opening, and installation of a new basket with a fresh
seal. We match the finish to the existing faucet and hardware where possible.
Best for: Leaks that appear to originate at the drain opening of the sink basin,
baskets that rock or move when touched, and any basket showing significant corrosion around the sink
opening.
Typical cost: $125 to $200.
Supply Line and Shutoff Valve Replacement
Flexible braided supply lines
and angle stop shutoff valves under the sink are a common failure point on Las Vegas homes. The mineral
content of Las Vegas water accelerates corrosion on the internal components of shutoff valves, making them
unreliable when operated after years without use — which is exactly when they are needed most. Supply line
replacement at the time of any sink repair is standard practice for us because the cost is minimal and the
alternative is a supply line failure that causes a cabinet flood. We use stainless braided supply lines rated
for Las Vegas water pressure and temperature conditions.
Best for: Any supply line showing kinks, corrosion at the fittings, or age beyond 7
to 10 years, and any shutoff valve that is difficult to turn or leaks at the packing nut.
Typical cost: $100 to $175 for supply lines and shutoff valve replacement at one sink
location.
Pop-Up Drain Stopper Repair
The pop-up drain stopper in a bathroom sink
is operated by a lift rod behind the faucet that connects to a pivot rod running through the drain body. In
Las Vegas, the pivot rod and the clevis strap it connects to corrode and seize from mineral deposits, causing
the stopper to stop moving, stay stuck in the open or closed position, or lose its seal entirely. Repair
involves removing the p-trap to access the pivot rod, freeing or replacing the corroded mechanism, and
reassembling the linkage. Most bathroom sinks in Las Vegas homes that are more than 5 to 7 years old have a
stopper mechanism that has been compromised by mineral corrosion.
Best for: Drain stoppers that will not stay in the up position, stoppers that will
not seal in the closed position, and lift rods that move without actuating the stopper.
Typical cost: $75 to $150.
Garbage Disposal Repair
We repair garbage
disposals as part of sink repair when the disposal issue is mechanical rather than electrical. A humming
disposal that does not spin has a jammed impeller — cleared by inserting an Allen wrench into the reset port
at the base and manually freeing the plate. A leaking disposal at the sink flange has a failed wax ring or
loose mounting assembly. A leaking disposal at the discharge connection has a failed gasket or loose clamp. A
disposal that does not respond at all has either a tripped reset button at the base of the unit or a failed
motor. We diagnose the specific failure and repair it or recommend replacement when the motor has failed and
repair is not cost-effective.
Best for: Humming disposals that do not spin, leaking disposals at the flange or
discharge connection, and disposals that do not respond to the wall switch.
Typical cost: $150 to $300 depending on the failure type. If the motor has failed and
the unit needs replacement, see our garbage disposal installation page →.
Drain Rough-In Connection Repair
Where the sink drain pipe enters the
wall, the connection to the drain rough-in can corrode, loosen, or develop a leak — particularly in older Las
Vegas homes where the original ABS or galvanized iron connections have been in service for decades. This
repair requires replacing the wall drain connection and re-seating the drain assembly from the p-trap back to
the wall. It is a less common repair but more involved than a simple p-trap swap when it is needed.
Best for: Leaks at the wall drain connection behind the p-trap, drain rough-in
connections showing visible corrosion or damage, and any drain assembly that cannot be made watertight at
the wall fitting.
Typical cost: $175 to $350 depending on access and whether the wall connection requires
modification.

What Affects the Cost of Sink Repair in Las Vegas?
We give you exact pricing before starting any repair. Here is what determines where your job falls in the range. Ask about our financing options:
Which Component Failed
A p-trap replacement or pop-up stopper repair involves inexpensive parts and straightforward labor. A full drain assembly replacement from basket to wall connection involves more components and more time. The specific failed component is the primary driver of cost.
Sink Location and Access
Under-sink repairs in a standard kitchen or bathroom cabinet with reasonable access are fast jobs. Tight utility spaces, outdoor sinks mounted on stucco walls, and garage sinks in awkward corners take more labor time. We account for access in the quote.
Condition of Surrounding Components
When we open the cabinet for a drain repair, we check supply lines, shutoff valves, and the full drain assembly. In Las Vegas, it is common for a single visible failure to exist alongside two or three components that are also near the end of their service life. We report what we find and quote any additional work separately before proceeding. You decide what gets done on this visit.
Whether Repair or Replacement Is the Right Answer
If the sink basin itself is cracked, permanently stained beyond cleaning, or the drain opening has been warped or pitted to the point where a reliable seal cannot be made, repair of the components underneath is a short-term fix on a failing sink. We tell you this honestly and give you the replacement cost alongside the repair cost so you can make an informed decision.
Hard Water Scale Severity
A p-trap that is partially blocked with soft mineral deposits clears quickly. A p-trap with hardened calcium scale that has mineralized solid over several years requires longer to clear and may need full replacement rather than cleaning. The severity of mineral buildup at the time of the repair affects labor time in proportion to how long the maintenance was deferred.

"The bathroom sink started to leak underneath. I tried everything that I know how to do to fix it, to no avail. I called Royalty Plumbing and they were able to have technician here the next day. It was a simple fix but unless you have that knowledge, you just wouldn’t know how to do it. The price was good, and the service man was friendly and quick! No mess left behind! This sink was installed about a year ago by another “plumber,” who didn’t do a very good job."
