Windows typically take 1-3 days to install depending on number of windows, home size, and issues like rotted wood frames.
Coastal Windows & Exteriors will let you know if we foresee any problems that may prolong installation. Most full-home projects complete in one day with two days for particularly large homes.
What Massachusetts, Maine, and New Hampshire Homeowners Need to Know:
- Project Size Variables: Installation time depends on the number of windows being replaced and your home size completing full-home replacements. Full-home replacements typically complete in one day while particularly large homes require two days for proper installation. Standard homes with 10-15 windows finish within a single-day.
- Frame Condition Impact: Rotted wood frames or structural issues extend installation timelines as repairs must be completed before new windows. Coastal Windows & Exteriors identifies these problems during initial inspection letting you know if we foresee any problems.
- Pre-Installation Staging: Installer outlines an installation plan based on your specific project, current weather conditions, and other variables.
- Installation Team Approach: One installer works on the outside and one on the inside depending on height and floor of your home. Coordinated two-person teams complete installations efficiently while maintaining quality standards throughout the entire project duration. Windows drop-shipped same day staying at room temperature with matching sealants ensuring proper adhesion and weatherproofing.
- Cold Weather Process: Installers remove one window at a time during cold weather minimizing heat loss inside your home significantly. Large openings like bow, bay, or picture windows may have plastic placed temporarily reducing energy loss.
