A repair sealed inside a wall is the one kind of work you pay for and can never afterward inspect.

You reach for the shower handle and nothing but cold comes out, or you walk past the utility closet and find a puddle spreading across the floor.

You're driving a screw into the wall to hang a floating shelf. On the last turn, the resistance changes: a soft catch, then a faint squeak that drywall alone doesn't make.

When is a water heater worth fixing, and when is it time to replace it outright?

Your sister-in-law is visiting for the weekend, and she wants an actual bath instead of the five-minute shower everyone in the house has settled into.

Your glasses come out of the dishwasher with a cloudy film no rinse aid fixes.

Two facts about the same house refuse to agree. The ceiling under the bathroom carries a dark line that gets a little longer every week, and the baseboard in the next room goes damp on the same schedule.

The fastest way to understand hydro jetting is to compare it with the tool most people already know: the drain snake.

You're coiling the garden hose against the side of the house when you notice the stucco under the eave has gone dark, a blistered stain trailing down from somewhere near the roofline you can't see from the ground.

A slab leak is a leak in one of the water lines that runs underneath or inside the concrete foundation slab your home sits on.

The recessed box behind a washing machine may be the only plumbing component in a house that gets installed, covered by an appliance, and then never looked at again.

A wet floor next to the water heater rarely means the whole thing has failed.

You have both hands on the shutoff valve where the line enters your house, and you have already turned it as far as it goes; there is no more give in the handle.

Replacing a water heater is a decision most homeowners make once or twice in a lifetime, usually in a hurry after the old unit quits.

The invoice from the irrigation repair is still sitting on the counter, the total circled where you paid it, next to an envelope from the water utility that arrived this week.

A clogged drain and a failing sewer line can start out looking almost identical: a slow flush, a little gurgle, a smell you catch once and then forget.

You crank the handle closed, walk away, and a minute later you hear it: the slow tap of water hitting the basin. The handle is off. The water is off. And the faucet is still leaking. If that has you wondering whether something is broken deep inside the fixture, you are reading the situation correctly. A faucet that drips after you shut it off almost always has one worn internal part that no longer forms a tight seal against the water pressure sitting behind it.

Three weeks in the house, and the billing period printed on the invoice is longer than that.

You crouch down at the same spot on the garage floor you photographed yesterday morning, running a thumb across the concrete to check it's really dry this time.

When one sink drains slowly, you probably have a local clog in that fixture's trap. When the toilet, the tub, and the floor drain all misbehave at the same time, something different is happening. The problem is no longer at any single fixture. It has moved to the pipe they all share.
