What you are actually paying for

Find the row that matches your situation. Quotes that differ wildly from each other usually differ in scope, not in price.

ScenarioTypical cost
Vinyl insert, double-hung, standard sizeThe most common residential replacement.$450–$900
Fiberglass or composite insertBetter thermal performance and dimensional stability.$700–$1,400
Full-frame replacement with trimRequired when frames or sills are compromised.$900–$2,000
Wood-clad, custom sizeTypical for historic and architectural applications.$1,400–$3,000
Impact-rated coastal windowRequired by code in many hurricane zones; may reduce insurance premiums.$1,200–$2,800

What moves the price

In descending order of impact. These are also the questions worth asking a contractor whose quote sits outside the range above.

  1. Insert versus full-frame

    An insert fits inside the existing frame and is cheaper and faster. Full-frame replacement removes everything to the rough opening and is required when the frame or sill is rotted.

  2. Frame material

    Vinyl is least expensive, fiberglass and composite sit in the middle, and wood-clad is the most expensive. Aluminum performs poorly thermally in cold climates.

  3. Glazing package

    Double-pane low-E is standard. Triple-pane, laminated and impact-rated glass each add meaningfully, and impact rating is mandatory in many coastal zones.

  4. Size and operation

    Casement and awning windows cost more than double-hung. Large picture windows and anything requiring two installers cost more to set.

  5. Condition behind the trim

    Rot at the sill and rough opening is common in older homes and is only discovered once the old window is out.

Can you do it yourself?

Limited DIY scope

An experienced DIYer can install an insert window on a ground floor. Full-frame replacement involves flashing and water management details where an error causes hidden rot, and most manufacturer warranties require certified installation.

Permits and inspection

A permit is usually required for full-frame replacement or any change in opening size. Bedroom windows must meet egress dimensions, which is an inspected item.

When this cannot wait

  • Failed seals with persistent condensation between panes
  • Rot in the sill or surrounding framing
  • Windows that will not open, a life-safety issue in a bedroom egress window
  • Visible daylight or water intrusion around the frame

Common questions

How much does it cost to replace all the windows in a house?
For a typical home with 15 to 20 windows, $8,000 to $20,000 for vinyl inserts and $18,000 to $45,000 for full-frame wood-clad replacement.
Do new windows pay for themselves in energy savings?
Rarely on energy savings alone — payback periods commonly exceed 20 years. Replace windows when they have failed, when comfort is genuinely poor, or as part of a broader renovation.
