TL;DR: Clear a 4-to-6 foot working zone around every window being replaced. Move breakables, cover floors and furniture you cannot relocate, and disconnect any blinds or drapery hardware attached to the frame. Crews work faster and your belongings stay safer when the path from door to window is clear.
Installation day moves quickly. Crews carry large frames, use power tools, and generate dust and debris throughout the work area. A little preparation the day before means fewer interruptions, fewer accidental bumps to your things, and a cleaner result. Here is what to do, room by room.
1. Clear a Working Radius Around Each Window
Measure roughly 4 to 6 feet out from the window sill in every direction. That space needs to be empty of furniture, area rugs, pet beds, plants, and any decorative items sitting on sills or nearby shelves.
Larger windows and sliding glass doors need more clearance because the frames are heavier and may require two or three people to maneuver them. If you have a window replacement involving multiple openings, clear the entire room if possible rather than moving things piecemeal throughout the day.
2. Remove Window Treatments and Hardware Completely
Blinds, shutters, curtains, and drapery rods should come down before the crew arrives. This matters for two reasons. First, installers need unobstructed access to the frame and the rough opening. Second, hardware attached to the frame itself, such as plantation shutter hinges, may be in the exact spot a fastener or trim piece needs to go.
Label your hardware with painter's tape so reinstallation goes smoothly. Store mounting brackets in a zip-lock bag taped to the corresponding curtain panel.
3. Protect Floors Along the Work Path
The path from your front or side entrance to each work area will see heavy foot traffic, tool bags, and possibly a cart or dolly. Hard floors scratch; carpet holds dust and debris long after the crew leaves.
Lay contractor-grade plastic sheeting or heavy canvas drop cloths along the full travel path, not just around the window. Secure the edges with painter's tape so they do not shift underfoot. If you have tile or wood floors that are relatively new, this step is worth spending a few extra dollars on thicker material.
4. Cover or Relocate Furniture That Cannot Be Moved
Large sofas, built-in shelving, or heavy beds that cannot be cleared fully should be covered with plastic sheeting. Impact window installation generates dust from cutting, grinding the existing frame, and applying sealant. That dust travels farther than most homeowners expect.
Electronics, televisions, and audio equipment are especially worth covering or moving to another room. Dust in a TV vent or speaker grille is harder to fix than relocating the unit for a day.
5. Take Down Wall Art and Shelving Near the Opening
Power tools vibrate walls. Any framed art, mirrors, or shelves within 3 to 4 feet of the window should come down and be stored flat in another room. This is especially true on interior walls, where the vibration from a reciprocating saw or hammer drill transmits readily.
If you have tile work or decorative finishes around window sills, photograph the existing condition before the crew arrives. That baseline documentation is useful if any question arises about pre-existing versus installation-related damage.

6. Secure or Move Pets to a Separate Area
Installation creates noise, open exterior wall sections, and multiple people moving in and out of the home. Pets should be confined to a room that is not being worked on, preferably with a door that stays closed all day. Make sure that room has no windows on the installation schedule.
Let the crew lead know where pets are located at the start of the day. This avoids doors being left open inadvertently in a room where an animal is contained.
7. Identify Your Electrical Panel and Any Outlets Near Windows
Some window openings are close to electrical outlets or switches. Installers are not licensed electricians and will work around wiring, but you should know in advance whether any outlet is recessed into the sill area or located in a wall section that may be affected. If you see wiring near any opening being replaced, flag it with the crew lead before work starts.
Also confirm where your electrical panel is in case a breaker needs to be toggled for a tool circuit. Knowing this ahead of time saves a search mid-job.
8. Plan for Dust on HVAC Vents
Installation dust is fine-particle and gets pulled into return air vents. If your HVAC system is running during the installation, consider closing supply and return vents in rooms where work is happening, or changing your filter immediately after the job is complete.
This is not a contractor requirement; it is simply a practical step that reduces how much construction dust circulates through your system. A fresh filter after a multi-window project is a reasonable habit.
9. Confirm Access and Parking Before the Day Starts
Crews often arrive in a truck and a separate vehicle carrying frames and materials. Confirm there is driveway or street parking available for both. In HOA communities, check whether contractor vehicle parking requires a visitor pass or advance notice to the association.
If you have a gate code, provide it in writing when you confirm the appointment. Do not rely on a verbal handoff from a week before.
10. Ask the Crew Lead One Question Before Work Begins
At the start of the day, ask: "Are there any areas you need me to clear that I may have missed?" Experienced installers know within a few minutes of walking a job whether anything is in the way. That one question surfaces small issues, such as a piece of furniture slightly too close or a rug the crew will need to roll back, before they become mid-job delays.
This is also the right moment to confirm how debris and old frames will be handled and where removed material will be staged before disposal.
Bottom Line
Interior prep is a short investment of time that pays off in a smoother, faster installation and fewer risks to your belongings. The core steps are consistent: clear the working zone, remove window treatments, protect floors and furniture, secure pets, and communicate with the crew lead before the first screw turns.

Frequently asked questions
Should I be home during the window installation?
It is generally a good idea to be present, at least at the start and end of the day, so you can answer access questions, confirm scope, and do a walkthrough before the crew leaves. If you cannot be there all day, designate a point of contact who can make decisions on your behalf.
How much dust should I expect from impact window installation?
Fine construction dust from cutting, grinding, and sealant work is common and travels beyond the immediate work area. Covering furniture and electronics in adjacent rooms is a reasonable precaution, and replacing your HVAC filter after a multi-window job helps clear residual dust from the air system.
What happens to my existing window treatments after installation?
Installers remove what is necessary to access the frame, but reinstallation of blinds, shutters, or curtain rods is typically outside the window installation scope. Confirm with your contractor before the job starts what is and is not included, and store your hardware in labeled bags so reinstallation is straightforward.
Do I need to do anything on the exterior of the home as well?
Exterior prep is usually handled by the crew, but clearing patio furniture, potted plants, and decorative items from directly below or in front of the work area helps the team move efficiently and prevents accidental damage to your belongings.
