    Learn About Siding Installation

    Priced per window,
    and what changes it.

    The number per window

    Replacement windows from 2FL run from about $700 to $2,500 per window. That is our own range rather than a national average, and where a window lands in it comes down to two things: the window itself, and how it goes into your wall.

    The window

    We install vinyl, composite and wood windows. Size and style matter too: a large picture window or a casement costs more than a standard slider, and the glass package changes it again.

    How it is installed

    There are three ways a window goes in, and they are priced differently. A retrofit fits the new window inside the existing frame, which works where the old frame and sill are sound. A fin set installs a new window with a nailing fin, fastened and flashed into the wall itself. And the Rain Jacket Flashing System, the installation method 2FL developed and patented, integrates the new window with the existing building paper, so it can be done without replacing your siding. Your estimate names which one each opening gets.

    A whole house

    A whole-house price is built opening by opening, so the way to estimate it is the per window range times the number of windows you are replacing. Houses with more large or specialty openings land higher.

    Timing, rebates and paying

    Most products take 4 to 6 weeks from signing to installation, because the windows are built to your measurements. If Puget Sound Energy supplies your home, replacing older single or double pane windows may qualify for a rebate: we send you the documents and you file online, and our rebates page has the current terms. You can also spread the cost through our financing partner, Hearth.

    FAQ

    WINDOW REPLACEMENT COST - WHAT PEOPLE ACTUALLY ASK

    A replacement window from 2FL runs from about $700 to $2,500, depending on the window you choose and how it is installed. A firm price needs someone to measure and look at each opening, because the frame, the sill and the wall around them decide which install method fits.

    Because each one is priced on its own size, style, glass and install method. A large picture window, a casement or an opening with a rotten sill will cost more than a standard slider in a sound frame, even in the same room.

    In general, vinyl costs the least, wood the most, and composite falls between them. Vinyl is low maintenance, wood has the look many older houses were built with, and composite gives you some of that look with less upkeep. The frame material is one of the two things that move a window across our range.

    A retrofit, where the new window fits inside the existing frame, is the simplest. A fin set window is fastened and flashed into the wall itself, which means more work around the opening. The Rain Jacket Flashing System, our patented method, seals the new window into the existing building paper without replacing your siding. We tell you which one each opening needs, and why, before you sign.

    Multiply the per window range by the number of windows you are replacing, then expect larger and specialty openings to push it up. That gets you a ballpark. The real number comes from measuring every opening, which we do at the estimate, free.

    Low-E coatings and gas-filled panes raise the price of each window and cut the heat that escapes through it. They also matter for the Puget Sound Energy rebate, which asks for replacement windows rated at a U-factor of .30 or better.

    You do, and we make it simple. If Puget Sound Energy supplies your home and you are replacing older single or double pane windows, we send you the documents the rebate needs and you file them online. The current amounts and who qualifies are on our rebates page.

    Yes. Buy three energy-efficient vinyl windows and get the fourth free, with installation included, and a Puget Sound Energy rebate can apply on top where you qualify. Ask about it at the estimate.
