A replacement window is built to the opening it goes into, not pulled off a shelf, so most of the work happens before anyone shows up with tools. The consultation sets the size and the style, a custom unit typically takes a few weeks to build, and installation day itself is often the shortest part of the project. Knowing the sequence makes it easier to tell good work from rushed work while it is happening in your house.
The Consultation Sets Everything Else
The first visit is an assessment of the openings, not a sales call with a tape measure. Each opening gets measured at three points across the width and three down the height, and the smallest number is the one that gets ordered. Openings settle out of square over time, especially in homes built on Georgia's red clay, so the installer also checks the diagonals to see how far the frame has drifted. That reading determines how much shim space the new unit needs.
Because every window is built to those numbers, changing your mind after the order goes in means starting over. Settle the style questions during the consultation, since single-hung, double-hung, casement, awning, and picture units all operate differently once they are in the wall, and the sash configuration is fixed the moment the order ships.
Two Ways A Window Gets Replaced
Which method an opening needs depends on the condition of the existing frame, and it is worth asking which one your quote covers.
- Insert replacement, sometimes called a pocket install. The old sashes and stops come out, the existing frame stays in place, and the new unit fits inside it. Interior and exterior trim are left alone, and the finished window loses a small amount of glass area to the doubled frame.
- Full-frame replacement. The frame comes out down to the rough opening, which exposes the sill and studs and allows new flashing and a sill pan to go in. This is the method a rotted or water-damaged opening requires.
- Openings where the wall has to be opened up either way, such as a window set in brick veneer or one where the sill has failed, are the ones most likely to add a day to the schedule.
Soft wood at the sill, stained interior trim, or a sash that has swelled tight against the frame usually points toward the second method. Those conditions are easier to price before demolition than after, which is why the assessment should include a look at the sill rather than just the numbers.
What The Crew Does At Each Opening
Work runs one opening at a time so the house is never sitting open. Floors and furniture below the window get covered, the interior stops come off, and the old sashes come out. The opening is then cleaned back to bare framing or bare frame, depending on the method.
The new unit is set in dry and checked before anything is fastened. Shims go in at the corners and at the lock points, and a good installer operates the sash at that stage, because a window fastened out of square will bind later even though it looked fine on delivery. Once it is plumb, level, and square, the unit is fastened, the gap around it is filled with low-expansion foam or fiberglass rather than standard spray foam that can bow the frame, and the exterior is sealed.
Sealing Details Worth Watching
The exterior seal is where a Georgia install either holds or fails. Wind-driven rain during a summer storm hits the wall sideways, so the sides and head of the window get a continuous bead while the bottom exterior edge is deliberately left open, or the weep holes in the sill are left clear. Sealing that bottom edge shut looks tidier and traps any water that gets in behind the frame.
Caulk also needs cure time. Applying it to a wall still wet from a morning storm, or in the middle of an August afternoon on a sun-facing elevation, gives a weaker bond than the same work done on a dry, moderate day. Where new siding and exterior painting is part of the same project, the window goes in first so the new courses and the finish coat can be run tight to the finished frame.
The Final Walkthrough
A final walkthrough with the crew before they leave is the last step on any exterior job. Walk each opening and check three things:
- Every sash opens, closes, and locks with the window in its final fastened position, not just before the trim went on.
- The caulk lines are continuous at the sides and head, with the weep holes at the sill clear and unpainted.
- Screens fit their own openings, since screens on a multi-window order are sized per unit and are easy to mix up between rooms.
Interior trim and touch-up paint sometimes follow a day or two later, depending on the method used. Old units and packaging should leave with the crew.
