Tip: Get at least 3 quotes from licensed window installers. Ask about Energy Star rated windows — they qualify for a 30% federal tax credit up to $600 per year.

Replacement: Same-size replacement adds 15% to labor for removing old windows, cleaning the frame, and ensuring a weathertight seal. Existing trim and framing are reused.

How We Calculate

Our window installation calculator estimates project costs based on number of windows, window type, and project type. Material and labor costs are calculated per window, with labor adjusted by a project type multiplier.

How the math works: Material cost = count × material price per window. Labor cost = count × labor rate per window × project type multiplier. Total = material + labor. The multiplier adjusts labor: new construction is 1.0×, replacement (same size) adds 15% (1.15×) for removal and cleanup, and retrofit (resize opening) adds 40% (1.4×) for framing and structural work.

Window Type Comparison

Single-Hung Vinyl ($150–$300 material, $150–$250 labor) has a fixed upper sash and operable lower sash. Most affordable operable window. Good for bedrooms and standard rooms.

Double-Hung Vinyl ($200–$400 material, $150–$300 labor) has two operable sashes that tilt in for easy cleaning. Most popular residential window. Excellent for any room.

Casement ($250–$500 material, $200–$350 labor) cranks open outward for maximum ventilation and the tightest seal. Best energy efficiency of any operable window. Ideal above sinks and counters.

Sliding ($200–$400 material, $150–$300 labor) slides horizontally — good for wide openings and easy operation. Low maintenance with no cranks or springs. Popular for contemporary homes.

Picture / Fixed ($150–$350 material, $100–$200 labor) does not open — lowest cost and best energy efficiency. Creates unobstructed views. Often paired with operable windows on each side.

Additional Cost Factors

Our estimates cover window units and installation labor. Not included: interior trim ($50–$150/window), exterior capping ($75–$200/window), window screens ($25–$50 each), Low-E or triple-pane upgrades ($50–$150/window), custom sizes (20–40% premium), structural headers for new openings ($200–$500), and permit fees ($50–$200).

Frequently Asked Questions

How much does window installation cost? +

Window installation costs $250–$750 per window depending on type. Single-hung vinyl is $300–$550/window, double-hung vinyl $350–$700, casement $450–$850, sliding $350–$700, and picture/fixed $250–$550. A typical 15-window home costs $5,250–$10,500 for new construction.

What type of window is most cost-effective? +

Double-hung vinyl windows at $350–$700/window installed offer the best value. They're affordable, energy-efficient, easy to clean (tilt-in sashes), and widely available. Single-hung vinyl is cheaper ($300–$550) but less convenient to clean.

How many windows does a house need? +

A typical home has 8–15 windows. Small homes (1,000 sq ft) average 6–10 windows. Medium homes (1,500–2,000 sq ft) have 10–18 windows. Large homes (2,500+ sq ft) may have 20–30+ windows. Building codes require egress windows in bedrooms.

Are new windows worth the investment? +

New Energy Star windows save $126–$465 per year on energy bills (EPA estimates). The federal tax credit covers 30% of costs up to $600/year. You'll also gain improved comfort, less noise, and increased home value (70–80% cost recovery at resale).

Should I replace all windows at once? +

Replacing all windows at once saves 10–15% vs. doing them in batches (volume discount, single mobilization). Most contractors offer per-window pricing that decreases with quantity. If budget is limited, prioritize north-facing and oldest windows first.

How long do new windows last? +

Vinyl windows last 20–40 years, wood 30–50+ years, fiberglass 40–50+ years, and aluminum 20–30 years. Double-pane insulated glass units last 15–25 years. Quality installation and proper flashing are key to maximum lifespan.

Can I install windows myself? +

Replacement windows in existing frames are a feasible DIY project for experienced homeowners ($100–$200 savings per window). New construction or retrofit installations require framing and flashing expertise — hire a professional for these. Improper installation voids warranties and causes water damage.
