What you're seeing
Sound familiar?
- A slow drip or a damp cabinet floor under a sink or behind the toilet
- A valve that won't turn, or turns and weeps from the handle stem
- Green or white crust on the valve body
- A supply line that's bulging, kinked, or older than the faucet
What's actually going on
That valve is an angle stop — the shutoff for just that fixture. Older ones are multi-turn valves with a rubber packing that dries out over the years, and on hard Twin Cities water the brass corrodes and the stem seizes. The first time someone turns it in a decade, it either won't move or it weeps. Braided supply lines age the same way, so the two almost always get replaced together.
The visit
What we do — and it's usually one trip
We come out, look at the actual problem, and give you a flat-rate price on the spot. If you approve, we fix it right then — the truck carries the parts this job needs.
Shut the water at the main and confirm the leak is the valve, not the supply line or the faucet connection above it
Replace the old stop with a quarter-turn ball valve — the kind that shuts off with a flick and doesn't have a packing to dry out
Fit new braided stainless supply lines to the faucet or toilet
Pressure the line back up, check every joint dry, and wipe down the cabinet before we leave
When it's more than a small repair
If the valve is soldered to a corroded galvanized stub-out, or the pipe behind the wall is the real leak, that's a slightly bigger repair — and we'll show you exactly what we found and price it in writing before touching anything more. Most of the time, though, it's a valve and two lines, done in under an hour.
If something's not right after we leave, we come back and make it right — no charge, no argument. That's the Loon Promise.
Good to know
Leaking shutoff valve questions, answered straight
Should I turn off my water before you get there?
If it's a steady drip, yes — the main shutoff is usually in the basement near the meter. If it's a slow weep, just put a towel down; there's no need to shut the whole house off before we arrive.
Can you replace just the valve and leave the supply line?
We can, but we'll usually recommend both. A supply line is the cheaper part and the one more likely to fail catastrophically — a burst braided line can flood a kitchen in an hour. Doing both at once is the honest value.
Is this really a one-visit job?
Yes. We come out, look at the actual valve, give you a flat price on the spot, and replace it right then if you approve. The truck carries quarter-turn stops and supply lines in every common size.
