I recently bought a house. Out with their under-sink reverse osmosis system and in with my reverse osmosis system. Problem was that their water in spigot was the type that punctures the copper pipe coming in from the wall. So what happens? Their little spigot with no hose on it decides it won't fully close. If it won't close then it will drip. I can't simply take off the spigot because that spigot has punctured the line. so, I called City Wide.
They cut off the old copper pipe with the puncture in it and welded a new piece on as well as a new quarter-turn shutoff valve. It cost me $174 which seems high for a small amount of work, but I think it was worth it. The copper coming from the wall wasn't that long and the hole was close to the wall meaning not much room to cut the pipe off or to weld a new sleeve on.
Could I have done it myself? Sure, but eff that... I would have cursed myself for 4 hours and had to go back to Lowes 14 times... and I probably would have burned myself doing all this.
On a different note... here lately I've been trying to fix things here and there and been calling people trying to set things up. It seems the trend is that people are hard to get a hold of and if you do they don't call back. This place I called, they said they'd have someone out in an hour and they came and did their job.
