What to Expect on Window Replacement Day
On window replacement day, the crew protects your floors and furniture, removes the old windows one opening at a time, inspects and prepares each opening, then sets, levels, insulates and seals each new window before trimming it out. They clean up, haul away the old windows, and walk the job with you so you can open, close and lock every window before they leave. Here is each step, and what you can do beforehand to keep the day smooth.
How to Prepare Your Home
A little preparation keeps the crew working on windows instead of moving furniture, and it protects your belongings.
- Clear the sills and the area in front of each window. A few feet of open space inside and out lets the crew work safely.
- Take down blinds, shades and curtains on the windows being replaced, or ask the crew whether they will handle it.
- Move fragile items off nearby walls and shelves. Removing a window can send light vibration through the wall.
- Plan for pets and kids. Openings are briefly exposed, so keep pets in a closed room away from the work.
- Make access easy. Unlock gates, note any alarm sensors on the windows, and park so the crew can reach the work areas.


What Happens at Each Opening
The crew starts by walking through the written scope with you so everyone agrees on which windows are being replaced and how. Then they work one opening at a time, so the house is never open to the weather all at once.
- Protect the area. Drop cloths go down on floors and over nearby furniture.
- Remove the old window. For an insert installation, the old sashes and stops come out and the frame stays. For full-frame, the whole window comes out down to the rough opening. Our guide to full-frame vs. insert replacement explains the difference.
- Inspect and prepare the opening. The crew checks for rot or water damage, cleans the opening, and confirms it is ready for the new window.
- Set the new window. It is placed, leveled and squared so it operates smoothly and seals evenly.
- Insulate and seal. Gaps around the frame are insulated, and the exterior is sealed against water and air.
- Trim and finish. Interior and exterior trim go back on or are replaced, then caulked.
How long does it take?
It depends on how many openings are being replaced, their size and type, and whether they are insert or full-frame. The timing is set in your written scope before the day arrives, so you know what to expect.
Cleanup and the Final Walkthrough
When the last window is in, the crew clears debris and packaging and hauls away the old windows. Then comes the step that matters most: a walkthrough with you.
- Open, close and lock every new window yourself.
- Check that screens are in place and the trim and caulking look finished.
- Point out anything that needs an adjustment so it can be handled before the crew leaves.
What if something comes up after installation?
Call or email the same local team that did the work. Keep your written scope with the product details on file, since it is the reference for any question about the windows or the installation.
The Bottom Line
Window replacement day goes smoothly when the scope is clear beforehand and the home is ready for the crew. New window and door installations are backed by our Lifetime Leak-Free Guarantee and a written lifetime limited warranty, with scope and warranty terms confirmed in writing before work begins. If you are still deciding whether you need new windows at all, start with glass replacement vs. full windows or the five signs to check. When you are ready, see our window replacement service or book an assessment.
Not Sure Which Path Fits Your Home?
