The fixtures in a La Mesa house get used all day, for morning showers, dinner dishes and everything else a busy household does. Wear is natural, and it shows up as a drip in the kitchen, a bathroom handle that gets hard to turn, or a shower that keeps running a little after it's off. The costly part is getting used to it, because a family can stop noticing a worn fixture while the fixture keeps getting worse.
Most of these have simple causes. A drip usually means a cartridge or seal is worn out, which is a small repair, and putting it off shows up on the water bill and on whatever the drip lands on. A handle that's hard to turn has wear reaching the parts inside. A shower that drips while it's off usually has a worn cartridge or seat, and a leak at the valve inside the wall is the same kind of problem in a place you can't see. Hard water can be tough on cartridges, seals and finishes.
The service covers kitchen, bathroom, shower and tub fixtures, with a repair when the fixture has life left and a replacement when it's worn out or you'd like something better. The contractor bases the repair or replace call on the fixture's actual condition and explains it in plain English, and the decision is yours.
