Real Faucet Work in Duvall
A Duvall homeowner had us out in July to replace a kitchen faucet that had stopped sealing properly. Bradyn pulled the old pull-down unit, checked the supply stops underneath while the sink was clear, and set the new faucet with a side lever.
It's a straightforward job when nothing underneath has corroded — and it's worth checking that while you're in there, because a seized angle stop turns a thirty-minute swap into an afternoon.
If you're in the valley, this is a job we do most weeks. Read about faucet repair in Duvall, or see everything we handle in Duvall, Carnation and Fall City.

Frequently Asked Questions
How much water does a dripping faucet waste?
A faucet dripping once per second wastes more than 3,000 gallons a year. On a metered supply that turns up on your bill every month. On a private well it's quieter but not free — you're running the pump harder than it needs to work, year round.
Should I repair or replace my faucet?
Repair a newer faucet with a simple fault — a worn cartridge or O-ring is quick and cheap. Replace an older one, or any faucet that's already failed twice. Parts for discontinued models get hard to source, and you can spend more chasing them than a new fixture costs.
Can I install a faucet myself?
Plenty of people do, and a straight swap is well within reach when the shut-off valves work and the connections come apart cleanly. Where it goes sideways is a seized angle stop or a corroded supply line. At that point you're not replacing a faucet, you're doing plumbing.
How long does faucet installation take?
Most take between thirty minutes and an hour once we're at the sink. What stretches it is everything underneath — seized shut-offs, corroded supply lines, or a mounting nut that refuses to move. We carry the common parts so those don't turn into a second visit.
Do you provide the faucet or should I buy it?
Either works. Buy the one you want and we'll fit it, or we'll supply one for you. If you're choosing it yourself, check the hole spacing matches your sink and pick a brand whose cartridges you'll still be able to buy in ten years.
Should the angle stops be replaced at the same time?
Often, yes — and it's cheaper to do it while the cabinet is already open. Angle stops seize with age, and a valve that won't shut off turns a simple faucet swap into a whole-house shutdown. We check them on every faucet job and tell you what we find.
Does well water change which faucet I should buy?
It can. Plenty of homes outside the Duvall and Carnation city cores run on private wells, and harder water is rougher on cartridges and aerators. Ceramic-disc cartridges hold up better than older washer designs, and a quality brand matters more than it would in town.
Why is my new faucet leaking?
Usually the installation rather than the faucet itself. The common culprits are an over-tightened or cross-threaded supply connection, a gasket left out, or a cartridge that never seated properly. Occasionally it genuinely is a defective unit. Either way, we'll find it and put it right.
