Sink Repair in Denver, CO
A sink that drains slowly, a faucet that drips, or water pooling in the cabinet usually has a cause we can find under the basin. We trace it to the trap, the supply, or the faucet, and fix what actually failed.
Service overview
Trap, supply, or faucet: find the fault
Sink repair in Denver is the diagnosis and fix of a kitchen or bathroom sink that drains slowly, leaks under the cabinet, or has a faucet that drips. A slow sink drain usually means buildup in the trap or the line beyond it, and the fix is clearing it at the source. Water in the cabinet usually comes from a trap connection that has worked loose, a supply line that has failed, or a faucet base that is leaking down through the deck. In Denver's older homes, the trap may be original brass or cast iron, the shutoffs may be seized, and the supply lines may be brittle, so we check the whole assembly under the sink rather than the one part that is visibly wet.
! Common warning signs
A sink that drains slowly
Buildup in the trap or the line beyond it slows the drain over months. Clearing it at the source restores the drain without pushing the blockage further down.
Water in the cabinet
A loose trap connection, a failed supply line, or a faucet leaking down through the deck all show up as water in the cabinet. Each has a different fix.
A dripping sink faucet
A kitchen faucet that will not stop running has a worn cartridge or washer inside. It drips around the clock and only stops when the part is replaced.
Scope of work
What a sink repair visit covers
A sink repair starts under the basin: we check the trap, the strainer and the supply connections to find whether the leak or the slow drain is in the fixture or the pipes below it. Here is what the visit covers.
-
01
Drain and trap diagnosis
We trace a slow drain through the trap and the line beyond it, so the blockage is cleared at its source.
-
02
Cabinet leak tracing
Water in the cabinet is traced to the trap, the supply line, or the faucet base, since each has a different fix.
-
03
Faucet testing
The faucet cartridge and seals are tested so a drip is fixed at the part that failed rather than by replacing the whole faucet.
-
04
Supply and shutoff check
The shutoff valves and supply lines under the sink are checked, since seized brass valves and brittle lines are common in older Denver homes.
Repair or replace: how the call is made
Most sink faults are worth repairing: a blocked trap or a worn cartridge is a part swap. A corroded trap and supply assembly, or a basin that has cracked, is a different conversation, and we lay out the replacement option when the diagnosis points that way.
Call (720) 599-7253Tools and methods we use
Drain auger
Clears the trap and the line beyond it so a slow sink drain is fixed at the blockage rather than pushed further down.
Basin wrench
The faucet and trap nuts under the sink are reached with a basin wrench, so the assembly is serviced without taking the sink out.
Leak tracing
Finds whether water comes from the trap, the supply, or the faucet base, since each has a different fix.
Cartridge puller
A seized faucet cartridge is drawn out without damaging the body, so the repair stays a repair.
Local execution
Sink repair in Denver runs into the city's older kitchens and bathrooms. In Baker and Capitol Hill, pre-war homes often still have original brass traps and shutoffs under the sink, and the valves have seized after decades. In Park Hill and Speer, 1920s and 1930s homes mix original plumbing with later replacements, so the assembly under the sink is often a mix of materials that needs care. Denver Water reports hardness of about 89–105 mg/L (5.2–6.1 gpg), and that mineral load clogs aerators and stiffens faucet cartridges across the city.

What to tell us when you call
Sink draining slowly or leaking? Call to book a visit
What to do while you wait
A slow sink drain is an annoyance, but water in the cabinet can damage the cabinet floor and the wall behind it. Call (720) 599-7253, describe the sink and the fault, and we will confirm availability when you call. If water is pooling in the cabinet, shut off the angle stops under the sink and place a bucket beneath the trap.
What to expect from your sink repair
Call and describe the fault
Call (720) 599-7253 and tell us which sink it is and what it does: drains slowly, leaks in the cabinet, or drips. We set a time that fits your day.
On-site diagnosis
We trace the drain, check the trap and supply connections, and test the faucet so the fault is found before any part is replaced.
Repair and testing
Once the blockage is cleared or the worn part replaced, the sink is run and the cabinet checked: the drain must run clear and the cabinet stay dry.
What shapes the cost of sink repair in Denver
The price of a sink repair depends on whether the fault is in the drain, the trap, the supply or the faucet, so no price is published on this site. Call and describe the fault, and we will talk through what decides the price before agreeing to anything.
The fault itself
The scope follows the diagnosis: a blocked trap, a failed supply line and a leak in the cabinet are three different repairs.
Age of the assembly
A recent trap and supply assembly is a straightforward repair. Original brass or cast-iron parts that have corroded take more care to service.
Access under the sink
A sink repair is worked from below the basin, so access decides the visit: a clear cabinet with working shutoffs lets us reach the trap and the supplies, while a packed cabinet with seized valves has to be cleared first.

Frequently asked questions
Why is my sink draining so slowly?
Buildup in the trap or the line beyond it is the usual cause, and it slows the drain over months. We clear the blockage at its source so the drain runs clear again.
What causes water in the cabinet under the sink?
A loose trap connection, a failed supply line, or a faucet leaking down through the deck. We trace the water to its source before replacing anything, because each cause has a different fix.
Why does my sink faucet keep dripping?
Most often a cartridge or washer in the faucet that no longer seals. We identify the faucet first, so the replacement part matches the fixture and the drip stops for good.
Should I repair or replace my sink?
When the fault is a blocked trap or a worn cartridge, repair is usually the right call. When the trap and supply assembly are corroded through, or the basin itself has cracked, replacement enters the conversation — and we lay out both options after the diagnosis.
