How to Choose Replacement Windows
Quick Answer
Work through four decisions in order: frame material (vinyl, fiberglass, or aluminum), window style (picture, casement, sliding, and others), installation type (retrofit vs. new-construction), and finally brand/product line. Getting the order right keeps the process manageable instead of overwhelming.
1. Choose a Frame Material
Start with vinyl, fiberglass, or aluminum. Vinyl is generally the most accessible and low-maintenance; fiberglass offers more structural strength and paintability; aluminum supports the slimmest frames and largest glass areas. See our material comparison guide for detail.
2. Choose a Window Style
Picture, casement, single-hung, double-hung, sliding, awning, and bay/bow windows each suit different rooms and architecture. Larger, more open spaces often favor picture or large architectural windows; bathrooms and kitchens often use casement or awning styles for ventilation.
3. Decide Retrofit or New-Construction
If your existing frames are in good condition and you're not changing the opening size, retrofit installation is typically faster and less invasive. If you're remodeling, adding a room, or changing an opening's size or shape, new-construction installation is generally required.
4. Consider Energy Performance
Glazing options like dual-pane construction and Low-E coatings affect how a window performs in Southern California's sun. See our energy-efficient windows page for more detail.
5. Talk Through Brand & Product Line
Once you know your material, style, and installation type, your consultant can walk you through which brands and product lines are available for your project.
