Window installation day goes smoothly when homeowners know what to expect and have prepared their home properly. Here's exactly what to do before, during, and after your window replacement project.
Before Installation Day: Interior Preparation
Clear the Work Area Around Each Window
Move furniture at least 3–4 feet away from each window being replaced. This gives the installation crew room to work safely and protects your furniture from dust and debris. Remove any window treatments — curtains, blinds, shades, and valances — and store them safely. If you have heavy furniture that's difficult to move, let us know when scheduling and we can discuss solutions, but generally the more clearance you can provide, the faster and cleaner the installation will go.
Protect Valuables and Fragile Items
Window installation generates dust and vibration that can affect items near the work area. Remove artwork, photos, and fragile decorative items from walls and shelves near each window. Cover electronics and furniture that can't be moved with drop cloths or plastic sheeting. Our crew will lay protective coverings on floors and work areas, but protecting your valuables in advance gives you peace of mind.
Prepare for Noise and Dust
Window replacement is not a quiet process — expect the sounds of old windows being removed, new windows being fitted, and caulking and trim work being completed. If you work from home, plan to use a room away from the installation areas or schedule calls for times when work won't be happening in adjacent rooms. Dust is minimal with modern installation techniques, but some fine dust is inevitable. Close interior doors to rooms not being worked on to contain dust.
Before Installation Day: Exterior Preparation
Clear the Exterior Work Area
Move patio furniture, potted plants, garden decorations, and any other items away from the exterior of windows being replaced. Trim back any shrubs or plants that are growing close to window frames — this gives the crew access and prevents damage to your landscaping. If you have a gate or fence that restricts access to the back or sides of your home, make sure it will be unlocked on installation day.
Secure Pets and Inform Household Members
Keep pets secured in a room away from the installation areas — open windows and exterior doors create escape opportunities, and the noise and activity can stress animals. Make sure all household members, including children, know that a crew will be working throughout the home. If you have a home security system, disable any sensors on windows being replaced for the day to avoid false alarms.

During and After Installation
What to Expect During the Installation
Our crew will arrive at the scheduled time, introduce themselves, and walk through the project scope with you before beginning work. Installation proceeds window by window — old windows are removed, the opening is inspected and prepared, the new window is set and secured, and exterior and interior trim and caulking are completed before moving to the next window. Most full-home replacements of 10–15 windows are completed in a single day. You're welcome to observe the work, but please give the crew space to work safely.
The Post-Installation Walkthrough
After all windows are installed, we'll conduct a thorough walkthrough with you, demonstrating how to operate each new window, explaining the locking mechanisms, and showing you how to tilt in the sashes for cleaning. This is the time to ask any questions and to note any concerns — we want to address everything before our crew leaves. We'll also explain the warranty coverage and how to contact us if any issues arise after installation.
Curing Time for Caulk and Sealants
The caulk and sealants applied during installation need 24–48 hours to fully cure. During this time, avoid getting the caulk wet (don't wash windows or expose them to rain if possible) and don't paint over the caulk until it's fully cured. After curing, your new windows are ready for normal use. You can reinstall window treatments, replace furniture, and enjoy your new windows immediately after the installation walkthrough.
