Window Installation in Montreal: How to Prepare Your Home
Updated: Sep 25

Once your new windows are ordered, the next question is practical: what needs to happen before the installers arrive? Preparing for window installation in Montreal starts with confirming the work area, access arrangements and finishing responsibilities. A few clear decisions can make the installation easier to manage and help everyone understand what a completed project should include.
For households in Montreal and the West Island, that preparation may involve a narrow driveway, a shared entrance, a busy home office or several rooms being renovated at once. This guide explains what to discuss before installation day, how to prepare the rooms and what to review with the installer afterward.
Confirm the Scope Before Moving Anything
Review the accepted estimate and identify every opening included in the project. Use room names that everyone recognizes, such as “front bedroom” or “kitchen over the sink.” If two windows are similar, label them on photographs. This reduces the chance of confusion when several products arrive together.
Confirm what happens to the existing interior and exterior trim, who handles painting, and whether removal and disposal are included. Ask whether any blinds, alarm contacts or other accessories need attention from a separate provider. Selcan’s window installation services provide a useful starting point for reviewing the details of your own project.
Agree on Access and the Work Sequence
Ask which rooms will be worked on first and whether the crew needs access from both inside and outside. Identify the entrance they should use and discuss where tools, new windows and removed materials can be placed. A clear route matters especially where a large unit must pass through a hallway or around a stair landing.
For a shared building, confirm any access arrangements with the responsible person before the appointment. Discuss parking and delivery access without assuming that a public space can be reserved. Give the crew a contact number for someone who can answer project questions during the day, even if the homeowner plans to be elsewhere.
Create Space Around Each Window
Ask the installer how much working clearance is required for your specific windows. Move lightweight furniture, plants, lamps and breakable objects out of that area. Arrange help for heavy furniture rather than assuming the installation team will move it. Leave enough room for workers to carry materials and turn safely.
Remove items from the window ledge and nearby shelves. Consider pictures or mirrors close to the work area that could be disturbed by vibration. Keep displaced belongings away from the route to the door; clearing a window is less useful if the hallway then becomes difficult to navigate. Photograph any existing damage to nearby finishes so its condition is clear before work begins.
Prepare the Exterior Access
Check the outside of each opening as well as the inside. Move portable furniture, planters, hoses and garden decorations from the agreed work zone. Point out fragile landscaping, irrigation components and anything else the crew might not notice immediately. Discuss access to upper-storey windows before installation day.
In colder months, arrange a clear route through snow and slippery areas. In any season, ask who will monitor the forecast and communicate a weather-related schedule change. The installer will determine whether conditions are suitable for the work and materials.
Frequently Asked Questions
Do I need to leave the house during window installation?
Ask the installer. The answer depends on the work area, number of openings and household needs. Even if you remain at home, stay clear of active work zones and keep someone available for decisions.
How long does window replacement take?
There is no reliable single duration for every home. Opening size, access, installation method, finishing and hidden repairs affect the schedule. Request an estimate based on the actual scope and confirm how updates will be communicated.
Can I reuse my existing blinds?
Possibly, if their dimensions and mounting method remain compatible. Check the planned frame and trim changes before relying on reuse. Final measurements should reflect the completed installation.
