Decide the installation sequence
If windows and doors arrive on different schedules, agree how the project is phased and how finish work will be completed. Confirm responsibility for each opening.
Protect daily access
Plan at least one usable entrance and discuss pets, household routines, and temporary security. The provider should explain how the home is secured during work.
Plan for your property
Coordinate window sightlines, door finishes, hardware, and thresholds as a single project. Ask for separate window and door line items so your budget stays clear from the first conversation.
