Impact windows usually cost somewhere between $400 and about $1,350 per window installed, with premium brands and large openings running higher. HomeGuide’s 2026 guide puts the typical range at $400 to $1,200 per window, and This Old House reports an average of $1,250.
For a whole house, HomeGuide estimates $6,000 to $24,000 for 15 to 20 impact windows. The spread comes down to frame material, window style, size, glass package and brand.

- Brand lines cost more: HomeGuide lists Pella impact windows at $800 to $2,000 and Andersen at $1,200 to $2,500 installed.
- The main drawbacks are the upfront price and a heavier, more demanding installation.
- They’re easiest to justify on hard-to-reach openings and for homeowners who don’t want to put up shutters before every storm.
What impact windows cost on average
Two national guides give a consistent picture. HomeGuide puts impact windows at $400 to $1,200 per window installed, or $300 to $800 or more for the unit alone.
This Old House reports an average of $1,250 per window, with most installs falling between $1,175 and $1,350. It also gives a wider range of $300 to more than $1,700 once labor is included, depending on design and performance features.
By the square foot, This Old House puts hurricane-rated windows at $30 to $60 before installation. That figure helps when you’re pricing a large picture window or a wall of glass.
How that compares with a standard window
HomeGuide lists standard non-impact replacement at $450 to $1,500 for a fixed window or $300 to $1,500 for a single-hung. In its general window replacement guide, the average non-impact window runs $450 to $1,500 installed.
So the ranges overlap more than you might expect. The gap shows up most on larger openings and in premium product lines, where impact glass and reinforced frames add real cost.
Impact window cost by brand
Most major manufacturers sell one or more impact lines, and the brand has a clear effect on price. HomeGuide lists these installed ranges:
- Pella impact lines: $800 to $2,000 per window. HomeGuide names Defender and Hurricane Shield as Pella’s high-impact lines.
- Andersen impact windows: $1,200 to $2,500 per window. The Stormwatch package upgrades standard Andersen windows to impact protection.
- For comparison: standard non-impact Pella windows run $300 to $3,500 and non-impact Andersen windows $400 to $4,000, depending on size and series.
HomeGuide also notes that well-known brands such as PGT, Andersen and Pella cost more than others and offer higher performance grade ratings than average.
What drives the price up or down
Every quote is built from the same handful of variables. Knowing them helps you see where the money goes.
Frame material
HomeGuide says vinyl, fiberglass and wood frames cost more than aluminum but insulate much better, while aluminum is lighter and a little easier to install. This Old House adds that aluminum is common in coastal areas for its strength, even though it offers less insulation.
| Frame | What This Old House reports | Tradeoff to weigh |
|---|---|---|
| Aluminum | Strongest and cheapest, lifespan of 45 years | Doesn’t insulate as well and is prone to rust and corrosion |
| Vinyl | Middle-ground option lasting 20 to 40 years | Insulates better than aluminum with less maintenance |
| Wood | Superior insulation, up to 30 years with care | More maintenance, and can warp or rot in humid, salty coastal air |
In a hot, humid place like ours, that last row deserves attention. A wood impact window can be the right choice for a historic look, but plan for the upkeep.
Window style and size
This Old House explains that operable windows cost more because they need tighter sealing and more precise installation to keep their impact resistance. Casement windows, for example, carry extra hardware that raises the price.
Size matters just as much. Larger openings need more material and labor, and This Old House notes they may need extra anchoring or structural reinforcement, especially in older homes or high-wind zones.
Glass package
HomeGuide says low-E glass costs 10 to 25 percent more than standard glass, and tempered glass costs more than standard glass but is stronger. This Old House notes that hurricane-rated windows often combine low-E coatings with impact-resistant glass to meet performance requirements while improving efficiency.
Labor, access and permits
HomeGuide puts installation labor at $100 to $400 per window, or $30 to $65 per hour, and building permits at $50 to $200, usually pulled by the installer. Second-floor and hard-to-reach windows cost more to install.
This Old House adds that retrofit installations are typically less expensive, while full-frame replacements and masonry openings take more time and specialized labor. In high-wind regions, permits often include inspections to verify anchoring, which can affect the timeline as well as the cost.
Add-ons that show up on quotes
HomeGuide lists several extras you may see as separate lines:
- Weather stripping at $5 to $10 per window
- Stabilizer bars at $20 to $40 per window
- Ventilation stops at $10 to $50 per window
- Interior trim at $100 to $250 per window
Building a whole-house budget
You can rough out a budget from the published ranges before anyone visits. Count your windows, sort them by size, and multiply by the range that fits each group.
Here’s a worked example using HomeGuide’s $400 to $1,200 per window installed:
- Count the openings. Say the house has 12
