Short answer: published 2026 industry data puts a standard vinyl replacement window in Washington at roughly $600 to $1,300 installed per opening, with Seattle-area labor toward the top of that band. That is a regional average, not a quote. The number that matters is the one we give you after measuring your openings. This page is here so that number is not a surprise.
What you are paying for
Four things move the bid:
- Scope. What each opening needs changes labor and finish work more than most product upgrades.
- Material and line. Vinyl is the Washington workhorse. Fiberglass costs more and can be the right call on larger or darker-colored units. Within either material, moving up a window line, such as from Cascade to Milgard, adds cost per opening for the same installation labor.
- Glass. Double-pane low-E is the baseline. Triple-pane, specialty sizes, and tempered glass add cost because they add performance or are required by code.
- Access. A first-floor slider is a very different job from a third-story picture window over a roof.
Permits, if the city requires them for the scope, sit on top of that.
Ranges, not quotes
That per-opening figure is a starting point, not a ceiling. A handful of windows can land in the low thousands once scope and access are added. A mid-size house is often a five-figure project. Bay windows, sliding and French doors, and openings that need extra work cost well above a typical opening built around a standard vinyl window in a sound opening.
Your openings, your trim, and the work each opening needs will move the number, which is what a measure is for.
How to think about value
Replacement is not just about the utility bill. The usual reasons it pays off are mixed:
- Rooms that are comfortable to sit in during winter
- Glass you can see through
- A dry sill instead of a slow leak
- Less work for the heating system over a long gray winter
If someone promises a two-year payback from energy alone, ask them to show the math for your existing glass. Going from single-pane glass to a modern window is a different story from going from already-decent double-pane.
Rebates in 2026
The federal 25C window credit is over for new 2026 installs. Some utilities in Washington still rebate qualifying U-factors, especially when you are replacing single-pane or very poor metal-frame units. Programs differ by city and fuel. We will not print a rebate on an estimate unless it still exists for your meter.
Comparing two bids that don’t match
The most common reason one quote is double another is not markup. It is scope. Before comparing numbers, check that both bids include the same:
- Approach per opening. Two quotes for the same window are not the same job if they assume different work at the opening, even at the same price.
- Glass package. Double-pane Low-E and triple-pane are not interchangeable line items.
- Haul-away and disposal. Some bids leave it out.
- Permits, if the scope needs one. A lower bid that skips a required permit is not actually lower.
Ask each bidder to list the approach and the glass for each opening, not just a total. That is the only way to compare two numbers.
What an estimate from us includes
- Approach per opening
- Product and glass
- Labor, haul-away, and basic finish
- Lead time
- Anything we will not do (hidden rot, paint, etc.)
You do not need an exact window count to start. A few photos of each side of the house and a walkthrough are enough.
Price makes more sense when you can see what is actually being changed. The same window count can represent very different scopes.
CLEARVIEW JOB PHOTOWhat to look for
The price follows the scope, not the window count alone.
Use the photo to orient yourself, then use the numbered notes to decide what matters at your own opening.
Size, style, material, and glass package change the unit cost.
Different openings need different amounts of labor and finish work.
Rot, out-of-square framing, or repairs can expand the scope.
Height, siding, trim, disposal, and other site conditions affect the finished job.
Common questions
How much does one window cost in Washington?
Public 2026 guides often put a typical installed vinyl unit in the mid hundreds to low thousands, depending on size, glass, and how much work the opening needs. A measure beats any average.
Is there still a federal tax credit for windows?
The Section 25C energy-efficient home improvement credit ended for property placed in service after December 31, 2025. Do not count on it for a 2026 install. Some Washington utilities still offer window rebates. Those change by fuel type and U-factor, so we check your utility at estimate time.
Why is a whole-house price so wide?
Ten small windows in a ranch is a different job from fifteen larger units on a two-story with custom sizes and openings that need work. Count, scope, material, and access swing the total more than the brand name on the glass.
