Window Replacement Cost Estimator
Calculate the cost of replacing your home's windows based on quantity, frame material, and glass type. See potential energy savings and detailed cost breakdowns.
Enter your window details to estimate replacement costs.
How It Works
Our window replacement calculator estimates costs based on the number of windows, frame material, and glass type. We include professional installation, interior and exterior trim work, and disposal of old windows.
Vinyl frames offer the best value with low maintenance. Wood frames provide classic aesthetics but require upkeep. Fiberglass is durable and energy-efficient. Aluminum is strong but conducts heat and cold.
Double-pane windows with Low-E coating are the current standard for energy efficiency. Triple-pane windows offer superior insulation in extreme climates but at higher cost. Energy savings shown assume replacing older single-pane windows.
Frequently Asked Questions
How long do replacement windows last?
Vinyl windows last 20-40 years. Wood windows can last 30+ years with proper maintenance. Fiberglass typically lasts 40+ years. Aluminum frames last indefinitely but seals may fail after 20-30 years. Quality of manufacturing significantly affects lifespan.
Are there tax credits for new windows?
Yes! The Inflation Reduction Act offers tax credits up to $600 for qualifying energy-efficient windows (must meet ENERGY STAR Most Efficient criteria). Many states and utilities offer additional rebates. Keep all receipts and Energy Star certifications.
Should I replace all windows at once?
Replacing all windows at once is more cost-effective—you get volume discounts and reduce labor costs. However, phased replacement is acceptable. Prioritize north-facing windows and those with failed seals (foggy glass) or drafts first.
What is Low-E glass?
Low-E (low emissivity) glass has a microscopic coating that reflects infrared light, keeping heat inside in winter and outside in summer. It reduces UV rays by 75%, protecting furniture from fading. Most double and triple-pane windows include Low-E coating standard.
How do I know if my windows need replacing?
Signs include: condensation between panes (seal failure), drafts even when closed, difficulty opening/closing, visible damage or rot, high energy bills, excessive outside noise. Windows over 20 years old may warrant replacement for energy savings even if functional.
