Professional Window Installation and Replacement in Portland, OR
Our experienced home window replacement crews are sure to keep your home clean and protected during the installation process. We’ll lay down drop cloths to protect the areas around the removal of each window both inside and outside of your home.
As the crew progresses with the removal of the casings and windows, they’ll assess if there is any damage around the openings left by old defective windows repairing the damage, if necessary before the new window is installed.
To complete the new window replacement, the exterior trim for the window will be mounted and sealed. The trim ensures a close-fitting seal to keep the weather and leaks out. Our window installers will vacuum the area around your windows and clean up your home thoroughly leaving it better than we arrived.

5 Elements of New Windows to Consider
- Energy Efficiency Ratings
- Frame Material (Vinyl, Fiberglass, Wood, Aluminum)
- Functionality
- Dual Pane vs Triple Pane
- Window Style
If your utility bill keeps crawling up season after season that’s a tell-tale sign that your type of windows aren’t energy efficient. Replacing old existing windows with new windows can reduce your monthly bills and keep your home temperature steady.
Window Styles and What They Actually Do for Your Home
Different window styles are designed to solve different functional needs. The best results come from matching each room with the right performance characteristics, not just replacing like-for-like.
Common options include:
- Double-hung windows for flexible airflow and easy maintenance
- Casement windows for tight sealing and strong ventilation control
- Sliding windows for simple operation and modern layouts
- Picture windows for maximizing natural light and outdoor views
- Specialty shapes for architectural design consistency
