Window Blind Installation Cost in 2026: What to Expect

Most contractors and window treatment companies price per window. A standard window runs $100-$300 installed with mid-range treatments. Large windows (over 48 inches wide), french doors, and unusually tall windows cost more because of larger treatment materials and more complex mounting. A typical 10-15 window home project runs $1,000-$4,500 total.

Vinyl mini-blinds run $15-$40 per window for materials. Faux wood or real wood blinds run $60-$200. Cellular shades run $75-$250 per window. Roman shades run $100-$400. Plantation shutters run $250-$600 per window installed. Motorized versions of any treatment add $100-$300 per window for the motor and controls.

Stock sizes from big box stores cost less but rarely fit modern windows perfectly - a 1/2 inch gap on either side is the standard compromise. Custom-cut or made-to-measure blinds and shades cost $30-$100 more per window but fit precisely, look more finished, and provide better light control. Most professional installations use custom-size treatments.

Manual corded or cordless treatments are the baseline. Battery-powered motorized shades add $75-$200 per window. Hardwired motorized systems add $150-$400 per window including electrical work. Smart home integration with voice control or app scheduling adds $50-$150 in smart hub equipment spread across all windows.

Standard inside-mount installation on a wood window frame is the baseline. Outside mount over trim adds minor complexity. Very high windows requiring ladders, skylights, specialty hardware for arched or angled windows, or installations requiring drywall anchors rather than frame screws all add labor time and cost.

“Are you measuring for an inside or outside mount, and what are the tradeoffs for my specific windows?”

Why this matters: Inside mount gives a cleaner look but requires sufficient window depth. Outside mount is more forgiving and provides better light blockage. A knowledgeable installer explains the tradeoffs for your specific window type rather than applying a one-size approach.

“What is the lead time on custom treatments, and do you handle the order directly?”

Why this matters: Custom window treatments take 2-8 weeks from order to installation. Contractors who manage the ordering should be able to give you a realistic timeline and confirm the order status. Delays in this phase are common and delay the whole project.

“What is your policy if a treatment arrives damaged or the wrong size?”

Why this matters: Custom orders occasionally arrive with defects or incorrect dimensions. Knowing whether the contractor or the manufacturer handles replacements - and the timeline - prevents an unpleasant surprise.

“Do the treatments you're recommending have child safety features (cordless or motorized)?”

Why this matters: Corded window treatments are a documented strangulation hazard for young children. Most states and manufacturers have moved to cordless or cord-management systems. If you have children under 6, confirm there are no accessible cords.

“What mounting hardware are you using, and is it appropriate for my wall and window material?”

Why this matters: Hollow drywall between window frames requires different anchoring than wood frames. Contractors who use drywall anchors for heavy treatments or shutters in locations without studs create installations that pull out of the wall over time.
