Question 1

How much does window replacement cost?

Accepted Answer

Window replacement costs $300–$1,200 per window installed, with most homeowners paying $450–$750 per window. A full home replacement (10–15 windows) typically runs $4,500–$12,000. Costs vary by window type (double-hung, casement, bay), frame material (vinyl, wood, fiberglass, aluminum), glass package (double vs. triple pane, Low-E coatings), and window size.

Question 2

What is the most affordable window replacement option?

Accepted Answer

Vinyl double-hung windows are the most affordable option, typically costing $150–$400 per window (before installation). Vinyl is low-maintenance, energy-efficient, and available in many styles. Fiberglass windows are more expensive ($400–$1,200 each) but offer superior durability and insulation. Wood windows are the most expensive ($600–$1,500+ each) but offer the best aesthetics for historic or high-end homes.

Question 3

How long does window replacement take?

Accepted Answer

A professional crew can replace 1–2 windows per hour. A full home replacement of 10–15 windows typically takes 1–2 days. Single window replacement takes 1–3 hours. Custom or large windows (bay, bow, picture) take longer. Most installations are complete in a single day with minimal disruption.

Question 4

Do replacement windows increase home value?

Accepted Answer

Yes. According to Remodeling Magazine's Cost vs. Value report, vinyl window replacement recoups approximately 68–72% of its cost in home value. Beyond resale value, new windows reduce heating and cooling costs by 10–25%, improve comfort, reduce outside noise, and eliminate drafts. Energy Star certified windows may also qualify for a federal tax credit of up to $600.

Question 5

What is the difference between insert and full-frame replacement?

Accepted Answer

Insert replacement (also called pocket replacement) installs a new window into the existing frame. It's faster, less expensive, and causes less disruption — ideal when the existing frame is in good condition. Full-frame replacement removes everything down to the rough opening and installs a completely new window and frame. It's required when frames are rotted, damaged, or when you want to change the window size.

Question 6

How do I know if I need new windows?

Accepted Answer

Key signs you need replacement windows: drafts around the frame even when closed, condensation between glass panes (seal failure), difficulty opening or closing, visible rot or damage to frames, single-pane glass (major energy loss), or windows over 20 years old. A window contractor can assess whether repair or replacement is the better option.
