Installing a Window on a Second Story

Nothing about an upstairs window installation is the same as the ground floor, and the running record window installation carlsbad madame and me holds shows that most of the difference lies in how the unit is handled. In Carlsbad, CA, many two-story houses near Interstate 5 have upper windows that are reached from inside, ladders being a poor fit for stucco walls and sloped yards.

Working from the inside

For a standard replacement, the old sash and frame are removed from the interior, and the new window is tipped in through the opening. This keeps the installer off a ladder and protects the exterior finish. The weight of a large double hung with insulated glass is manageable by two people when handled this way.

Heavy and oversized units

A big picture window or a wide slider with a double pane weighs enough that a suction cup lifter and a second person are needed. Glass can be removed from the frame first on some units to lighten them. The wrong lift on a clad window can crack the glass seal or twist the frame.

Scaffolding and ladders when needed

When the sill pan and flashing must be reached from outside, a scaffold or an extension ladder with a stabilizer is set on firm ground. Houses on slopes near Agua Hedionda Lagoon often need leveling pads under the legs. The exterior flashing is the one task that cannot be done from inside.

Wind and weather

The afternoon breeze off the coast can catch a large pane like a sail. Work on upper floors waits for calmer hours, and openings are covered before leaving so the marine layer does not wet the room. Temporary covers are screwed to the framing rather than taped to the stucco, and they are checked again before leaving, since a gust overnight can lift a loose cover and let damp air straight into a bedroom.

Egress and safety

An upstairs bedroom window may need to keep its clear opening for emergency exit, so a casement or a single hung is chosen with that in mind. Fall protection and protected floors below keep the job safe for the crew and the household. Lock hardware and screens are tested before the crew moves on, since a stuck lock on an upper floor is much harder to fix once the scaffold is down and the ladder is put away.
