A hot pan gets set down without a second thought. A glass of wine sits on the same corner overnight.

Rusty water on the first draw, a shower that quits when a toilet is flushed, water audible inside a wall: those three together point at the supply piping rather than at any one fixture.

The first sign usually shows up in the next room. A dark line along the base of the wall on the other side of the shower, or a strip of wood flooring a few feet from the bathroom door that has cupped and lifted at the seams.

In a test lab, a complete window is mounted into a rigid wall section framed like a house wall: glass, sash, frame, hardware, and fasteners, all as one assembly.

An addition is a second building placed against a first one. The house you already have has finished most of the settling it will ever do and found its position in the soil it sits on.

Rain lands on the roof first. It runs down the slope of the shingles into a gutter, gathers there, and drops out through a downspout at one corner of the house, then another at the opposite corner.

A door at the end of the hall swings open on its own if you let go of the handle.

Neither fiber-cement nor engineered-wood siding usually fails in the middle of a flat, uncut board.

A reach-in closet is a box with one rod across it and one shelf above the rod.

Almost every call that opens with the words backyard shade describes the same structure: posts, beams, evenly spaced slats overhead, the open garden-structure look.

Can I keep my boxes? That is the real question behind almost every cabinet project, and there's a way to answer it without guessing.

Noise crosses a space that once stopped it at a doorway. Cooking smells drift down a hallway they never used to enter.

A privacy fence has two faces, and two different people look at each one. You see the front of your own fence from your own yard.
