Bathroom faucet repair across the Denver metro
Your bathroom faucet drips at night, trickles when you want pressure, or the handle has gotten stiff enough that you brace the counter to turn it. That's almost always one worn part, not a dead faucet. We repair bath faucets across the Denver metro, and we diagnose the actual failure before we quote: a cartridge faucet that drips needs a cartridge, a two-handle compression faucet that drips needs a washer and seat, and the two repairs are not interchangeable. You get a written flat-rate quote before we touch anything, no money down, and Deft Plumbing is licensed, bonded, and insured in Colorado. You know the cost before we pick up a wrench.
Here's what a generic faucet listing won't tell you about a repair in this town: Denver Water runs 12 to 17 grains per gallon, hard enough that the calcium quietly welds itself to the moving parts inside your faucet. After repairing these across the metro, from Wash Park bungalows to the newer builds out past Green Valley Ranch, we've learned the mineral scale is usually the real culprit, not a defective faucet. A weak trickle is often a clogged aerator or a scaled cartridge, not a supply-line pressure problem. We figure out which before we quote, and if a repair won't hold, we'll tell you straight and quote a replacement instead.
Common bath faucet repair issues we fix in Denver
Faucet drips from the spout after you shut it off
On a single-handle faucet that's a worn or scaled cartridge. On a two-handle faucet it's a worn rubber washer or a pitted valve seat. We identify which faucet you have, replace the right part, and on a compression faucet we re-seat or replace the seat too, so it doesn't start dripping again in a month.
Weak or uneven flow from one faucet
Nine times out of ten this is a clogged aerator packed with calcium, or scale narrowing the cartridge ports. We pull and clean or replace the aerator first because it's the cheapest fix. If flow is still weak after that, we check the cartridge and the angle-stop supply valve before assuming you have a bigger pressure issue.
Handle is stiff, stuck, or grinds when you turn it
Mineral buildup binds the cartridge or the stem so the handle fights you. On Denver's hard water this is common past the 10-year mark. We free and lubricate or replace the cartridge. A handle forced for months usually cracks the cartridge, which is why a stiff handle becomes a drip if it's left alone.
Water leaks from the base of the handle
The O-rings or the packing nut seal under the handle have hardened and shrunk. Water seeps up around the handle every time the faucet runs. New O-rings and a fresh cartridge seal stop it. Left alone, that water runs down inside the valve body and into the cabinet.
Pooling water or a smell inside the vanity cabinet
The leak isn't always at the faucet. A weeping angle-stop shutoff or a cracked braided supply line drips into the cabinet and warps the floor. We trace the leak to its source and replace the shutoff and supply line as part of the repair, because reusing a 20-year-old crusted valve is how a clean fix turns into a callback.
Two-handle faucet you can't find parts for
Older Denver bathrooms often have a discontinued compression or cartridge faucet where the manufacturer no longer stocks the guts. We carry universal washers, seats, and common cartridge sizes on the truck. If the body itself is corroded through, we'll tell you honestly that a replacement is the smarter spend.
What to expect, start to finish
1. Phone triage
Call (720) 880-8064 during business hours. We ask whether it's one handle or two, where the leak shows up (spout, base, or cabinet), and roughly how old the fixture is. For most Denver bathrooms we can narrow the cause and quote a repair range over the phone.
2. On-site diagnosis
We confirm the faucet type, pull the handle and inspect the cartridge or washer and seat, check the aerator, and look inside the cabinet for a hidden supply-side leak. We identify the root cause, not just the symptom, before we quote.
3. Written flat-rate quote
You get a written quote covering the part, the labor, a new shutoff and braided supply line if the existing ones are scaled, and any aerator or O-ring work. No money down. No work starts until you sign off. If repair isn't the right call, we quote a replacement in the same visit so you can choose.
4. Repair on the spot when possible
We carry common cartridges, washers, seats, aerators, O-rings, and quarter-turn shutoffs on the truck. Most bath faucet repairs finish in the same visit without a parts run.
5. Descale and reassemble
We clear the calcium from the seat and ports so the new part seats clean, lubricate the moving parts, reset the cartridge or stem, and snug everything to spec without over-torquing the valve body.
6. Test and walkthrough
We run hot and cold, confirm the drip is gone under pressure, check the base and the cabinet for any weep, and verify flow at the aerator. You leave with a written warranty and a faucet that works like it should.
Why Bath Faucets Fail Early in Denver, and When Repair Beats Replacement
Most faucet-repair pages online treat a drip as a random failure. After repairing these across the Denver metro, our conclusion is blunter: the hard water here is almost always the reason. Denver Water and the surrounding Front Range utilities test in the 12 to 17 grains-per-gallon range, with Jefferson County areas often on the high end at 15 to 17. Anything over 7 GPG is officially hard, so we're running roughly double. That calcium and magnesium don't stay in the water. They drop out and crust onto the cartridge, the valve seat, the aerator screen, and the O-rings, which is why a faucet that should run smoothly for fifteen years starts dripping or stiffening at eight or ten in this city.
The repair you need depends entirely on the faucet, and this is where a lot of advice goes wrong. A modern single-handle faucet uses a cartridge, a sealed unit that mixes hot and cold. When it drips or stiffens, you replace the cartridge. A two-handle compression faucet, common in Denver homes built before the 1990s, uses a rubber washer pressed against a brass seat. When that drips, you replace the washer and dress or replace the seat. Putting a new washer in a cartridge faucet does nothing, and swapping a cartridge into a compression body isn't possible. We identify which you have first, because the wrong part is the most common reason a do-it-yourself drip fix fails within a week.
There's a line where repair stops making sense, and we'll name it instead of hiding it. If the faucet is under fifteen years old and the body is sound, a cartridge or a washer-and-seat repair is the right spend, often a fraction of a replacement. But if the valve body is corroded through, the finish is flaking into the water, or it's a discontinued unit where every internal part is failing at once, a repair just buys you a few months before the next leak. In that case we quote a replacement faucet honestly and let you choose. Either way, we replace the angle-stop shutoff and the supply line whenever they're scaled, the same way we do on all our faucet and fixture work. That's not an upsell. It's the part of the job that keeps a crusted 20-year-old valve from becoming your next midnight leak.

"Honest from the first call. They told me my old two-handle faucet just needed washers and a seat dressing instead of selling me a whole new fixture. The drip is gone and it cost a fraction of what I expected."

Denver bath faucet repair questions
Why is my bathroom faucet dripping?
It's a worn internal part, and which part depends on the faucet. A single-handle faucet drips when the cartridge wears out or scales up. A two-handle faucet drips when the rubber washer hardens or the brass valve seat gets pitted. Denver's 12 to 17 grain hard water speeds both up by crusting the moving parts. Replacing the right part stops the drip; replacing the wrong one does nothing, which is why we confirm the faucet type before we quote.
Should I repair or replace my bathroom faucet?
Repair makes sense when the faucet is under about fifteen years old and the body is sound, since a cartridge or a washer-and-seat fix is a fraction of a replacement. Replacement is the right call when the valve body is corroded through, the finish is flaking into the water, or it's a discontinued unit where every internal part is failing at once. We diagnose first and quote both so you choose, rather than defaulting to a replacement to pad the bill.
What's the difference between a cartridge and a washer faucet repair?
A cartridge faucet, common on single-handle models since the 1990s, uses a sealed cartridge to mix and shut off water. When it leaks or stiffens you replace the cartridge. A compression faucet, common on older two-handle Denver fixtures, uses a rubber washer pressed against a brass seat. When it drips you replace the washer and dress or replace the seat. The two repairs aren't interchangeable, so the first step is identifying which faucet you actually have.
Why does my bathroom faucet have low water pressure?
On a single faucet, the most common cause is a clogged aerator packed with mineral scale, which is a quick clean-or-swap fix. Scale narrowing the cartridge ports can do the same. We clean the aerator first because it's the cheapest fix, then check the cartridge and the angle-stop shutoff. Only if flow is still weak across the home do we look at whole-house pressure, since a single trickling faucet is usually a repairable local issue, not a supply problem.
Do you replace the supply line when you repair a faucet?
When the shutoff or supply line is scaled or weeping, yes. On Denver's 12 to 17 grain water, the old multi-turn angle stops crust up and become the next leak waiting to happen. If the valve and line are in good shape we leave them alone. If they're not, we replace the shutoff with a quarter-turn ball valve and run a new braided stainless line as part of the repair. We frame it as doing the job completely, not as an add-on.
Do you need a permit to repair a bathroom faucet in Denver?
No. A faucet repair or a like-for-like fixture swap on existing supply lines doesn't require a permit. Permits come into play only when the work involves relocating the drain or running new supply rough-in, typical in a remodel, and in that case we pull the permit and coordinate the inspection. A straight repair, you're covered without one.
