Window replacement pricing depends on many factors including window type, frame material, glass options, and installation complexity. We provide transparent, no-obligation estimates so you know exactly what to expect.
What Affects Price
Every window replacement project is different. These are the primary factors that determine your total cost.
Single-hung, double-hung, casement, bay, bow, picture, and awning windows each have different material and labor requirements that affect overall cost.
Vinyl frames offer the most affordable option, while wood, fiberglass, and composite frames cost more but provide different aesthetic and performance benefits.
Single-pane, double-pane, triple-pane, Low-E coatings, argon gas fill, and laminated glass all affect the price.
Larger windows require more material and labor. Custom sizes, non-standard shapes, and oversized windows cost more than standard dimensions.
Replacing multiple windows at once typically reduces the per-window cost. Whole-house replacement projects benefit from volume pricing.
Second-story windows, structural modifications, rotted framing repairs, and difficult access all increase installation costs beyond the base window price.
Window Types
Each window type has different material and installation requirements that affect pricing. Contact us for a quote specific to your project.
One fixed sash and one operable sash. The most budget-friendly option for standard window openings.
Budget-conscious replacements where ventilation is needed
Both sashes operate, allowing top and bottom ventilation. Easy to clean from inside. The most popular choice for DMV homes.
Most residential applications, especially upper floors
Hinged on the side, crank-operated to swing outward. Excellent seal and ventilation. Higher price point than hung windows.
Kitchens, bathrooms, and hard-to-reach locations
Project outward from the wall to create space and panoramic views. Complex installation with higher material and labor costs.
Living rooms, dining rooms, and master bedrooms
Fixed, non-operable windows that maximize views and light. Lower cost than operable windows of the same size since there are no moving parts.
Rooms where views and light are priority over ventilation
Horizontal operation with one or both sashes sliding. Good for wide openings where a crank window is impractical.
